We had such a fantastic experience working with O’Keefe Built on the rebuild of our old, sagging front porch. It was really important to us to maintain the original charm of our house, and the O’Keefe team completely respected that. They worked closely with us to stay within our budget and incorporate the materials and features we wanted, and we’re so thrilled with the final result! The new enclosed space feels like it was always meant to be part of the home.

From start to finish, every person we worked with was professional, communicative, and truly cared about the quality of the work. Pat helped us develop a clear quote and scope that aligned with our budget. Chuck was so patient and thoughtful as we honed the design together. Robert, our project manager, kept us updated every step of the way and was incredibly organized and responsive. Sergio and his construction team did an amazing job navigating the quirks of our older home and handled every unexpected challenge with skill. And Karcy’s follow-up after the project wrapped up was such a kind touch and made us feel truly valued.

O’Keefe Built exceeded our expectations not only in the quality of the finished project but especially in communication and professionalism throughout. We would absolutely work with them again when it’s time for our next exterior remodeling project!

I cannot recommend O'Keefe more highly to anyone. From the minute I put in an online inquiry for a quote, to the first follow-up call, to the on-site measurements, to the communication leading up to the project, to the absolute quality of every employee on-site and back office, to the installation of our new deck, to the clean up of the project, everything EXCEEDED our hopes and expectations. I have never had a smoother, more high quality project start to finish.
When I researched companies to bid out a new deck on our house, I invited 3 to give final bids, O'Keefe's bid was inline with the other bids, but the attention to detail and follow through during the bid process is what stood out and got us to choose them. The choice to use them was without even knowing how excellent the installation process would be as well as the incredible communication software they use between customer and project rep to keep everyone in the loop.
Everything was absolutely top notch.

We had a wonderful experience with the crew of O’Keefe Built. From the first meeting until the last, the team was exceptional. We loved how easy and yet detailed they made the process. The quote was easy to understand and vary depending on your choices. It was very transparent with no hidden surprises. The ongoing communication was second to none with the customer able to easily see notes, updates and daily logs in their tracking system. Our project manager and the construction crew were amazing, kind, respectful and very responsive. We cannot recommend O’Keefe enough. We are so happy with our new deck!

O’Keefe Built expanded our front porch and put a beautiful roof over it. We are extremely happy with the end result. The communication throughout the project and timeliness and dedication of the construction workers were top notch. We look forward to our next project with them.

I had a complex and extensive project that my original contractor severely mishandled. After being turned down by several other deck companies, Pat, the owner of O'Keefe Built, confidently took on the challenge. I could not be more thrilled with the results. The craftsmanship is stunning, truly a work of art. From the very beginning, the entire team maintained clear and consistent communication, keeping me informed every step of the way. Even when unexpected challenges arose, they handled everything with professionalism and ease. Without a doubt, this is a ten out of ten experience. I would hire them again without hesitation.

I love my new deck and am so appreciative of the O’Keefe team that built it. What a professional, skilled group of caring, dependable and knowledgable people! What impressed me the most when choosing a deck builder was that they responded to my call immediately and listened to my wishes. They designed and drew up plans, working with me to stay within my budget. The deck was finished in two weeks because the crew arrived everyday on time and some days even stayed until dark. They use quality materials and pay attention to detail so the deck looks beautiful and we are now enjoying and relaxing on our new outdoor space. Thank you everyone at O’Keefe Built!

I really can't say enough good things about our experience with O'Keefe. They gave us a detailed plan and explained the different phases for the project. They documented every step so we knew what to expect and kept us updated so we always knew where we were at in the process. They listened well to us, going above and beyond to get us the best final product possible. For example, we had researched materials and were interested in a deck material that was different than what they had suggested. Instead of trying to talk us out of it, Derek took the time to look into the material we had found. Another example -- we had a tricky downspout to deal with. Chad completed the original plan but decided he could do better. So he came back, redid that piece and brought in a gutter company to complete the finish touches. All of their team members were professional and polite. They cleaned up the site every day. Everything about our experience with O'Keefe was positive. Their craftsmanship is top-notch and we're thrilled with our new deck. If we ever move and need another deck, they'll be the only company we call!

The O'Keefe team built the balcony with underlying patio to look like it was always a part of the home just as I envisioned. They were also responsive to modification requests as the project unfolded. I recommend them for your balcony or deck build.

I chose O'keefe Built for my backyard renovation project. The project involved the design and build of a custom patio and pergola with surrounding fencing. The project also involved working with another landscaping contractor.
I was impressed in general with how the project was organized. They incorporated useful web tools to keep everyone updated on what was going on. There were a lot of logistical issues to deal with that benefitted from this approach.
I was also impressed with how they accommodated change requests that I made during the project including the addition of downspout drains underneath the concrete patio.
The attention to detail was evident in all aspects of the project including the fence construction, pergola, drains, and patio.
In the end I was pleased with the result and would recommend O'keefe Built Inc for your next home improvement project.

We had an exceptional experience with O'Keefe Built for our extensive outdoor project. The job involved constructing a large, mineral-based composite deck, covered by a gable roof on one side and a flat roof on the other. The flat roof features a section with louvers that open, while the gable side boasts beautiful skylights. A remarkable design element includes the curved deck boards that seamlessly flow down the stairs onto the paver patio, adding a unique touch to the overall aesthetic.

This was a significant project that we had been planning for years. After interviewing several contractors, we finally chose O’Keefe Built, and we couldn't be happier with our decision.

We were thoroughly impressed with the quality of work, craftsmanship, and unwavering commitment to excellence. On the rare occasion that something didn’t meet our expectations, our project manager, Chad, promptly addressed and resolved the issue. Chad's attention to detail, ability to bring our vision to life, and his friendly, calm demeanor were greatly appreciated. The crew was hardworking, respectful, and highly experienced, reflecting the high standards of the entire O’Keefe team. We wholeheartedly recommend them from start to finish.

We are absolutely thrilled with the final result and are thoroughly enjoying our new covered deck and patio. We highly recommend O’Keefe Built to friends and neighbors who want to enhance their outdoor space and work with a top-notch contractor.

Thank you, O’Keefe Built, for transforming our previously hot and unusable backyard into a wonderful extension of our home, one that we will enjoy for years to come!

We had a very positive experience working with O’Keefe Built. Friendly and responsive people/crews who really cared about getting our project done well. They maintained high standards for the work and made sure we were happy with the finished product. Two thumbs up.

O‘keefe did a great job of communicating and designing our new front porch. Felipe Gomez did the entire build and we couldn’t be happier. He has a very high attention to detail and makes sure that everything looks perfect. I highly recommend anyone looking for an outdoor remodel to contact O’Keefe.

O'Keefe Built replaced our ancient tiny "deck" with a beautiful new covered one, tied in perfectly with our existing roof. They also replaced an old cracked concrete pad next to the deck with a nice new one made of tinted stamped concrete. The entire team was a pleasure to work with, and Chad (the project manager) was very responsive. I don't think I ever waited more than an hour for a response to a question, and he accommodated many little tweaks and requests along the way. The work crews were great as well, and their progress was astonishingly quick. We couldn't be happier with the result! Definitely will be in touch with O'Keefe Built for any additional projects we come up with.

I cannot say enough good things about O’Keefe Built. Starting with the staff…especially Derek and Chad, the folks behind the scenes, and the carpenters…our pergola is beautiful! From the basic build to the finish stain they all were outstanding. We love it! I highly recommend their services.

Projects like this overwhelm me and I’m so happy to say that working with O’Keefe was the perfect way to handle that. Excellent, responsive and proactive communication, super nice people and my yard looks amazing. There were small typical bumps in the road (as there always are) and things were handled quickly and completely all while continuously assuring me that I wasn’t being a pain in the butt. They are genuine people and are great at what they do. I’ll be using them again!!

We have had several projects completed by O'Keefe Built over the last few years, with which we have been extremely happy. A few years ago, O'Keefe rebuilt our front steps with landing and railing. After that, they replaced our upper and lower decks. Finally, this past winter, our old wooden fence (that surrounded our front patio) has been replaced with a beautiful and fire-resistant Hardie Board enclosure! For each of these projects, we chose O'Keefe over other bids because we have been so pleased with the high quality of their work and their consistent professionalism and communication through all phases of the projects.

All members of their staff, from the administrators and supervisors to their outstanding skilled workers, have been a pleasure to work with. And we are delighted with how each of the projects has turned out.

From the initial bid to the final product, O’Keefe Built has been a pleasure to work with. Jerry made several changes and suggestions on the original bid, and Chad & Sergio were extremely communicative and great to work with on the deck project.

We used O’Keefe for both the design and construction of our deck. It was clear that their staff is very experienced with many types of decking product products. We appreciated being able to evaluate different systems and pick the one that best fit our project. Our deck was a large and 12 feet above the ground and included the stairs. It was a challenging project, but we are very pleased with the final product. We would use O’Keefe again.

We were extremely impressed with O’Keefe Built. Our deck wasn’t a run of the mill project. O’Keefe worked with us to design and construct a stunning deck and pergola within the difficult constraints of our lot and HOA requirements.

Working with honest, kind people is of paramount importance to us and you won’t find better people than the team Pat O’Keefe has assembled. From inception through completion, communication was excellent. Everyone was professional, informative, and genuinely kind.

We couldn’t have asked for a better project manager than Chad. He kept us informed each step of the way and ensured we understood each part of the process. He went out of his way to introduce himself to our neighbors and let them know to contact him if they had any questions about our construction project.

Our project was completed on time and the crew was outstanding. At the end of each work day the site was cleaned, swept and their tools and materials were carefully stowed.

We only wish they did basement finishing! We can’t recommend O’Keefe Built highly enough.

From start to finish, we enjoyed working with the O'Keefe team for our backyard project. Jerry helped get our vision in motion of removing our old deck and replacing it with a beautiful patio with pavers and retaining wall. The video he created was super helpful in explaining the products and scope of the project. He suggested Low Voltage Lighting to finish the look and provide necessary lighting for evening patio use. Chad managed the project and communicated with us well throughout.
Jorge and the construction team paid attention to detail, asking for our input as needed to ensure the final product was to our liking. My favorite part of the patio are the waterfall style steps out the door. It's a gorgeous transition from the house down to the patio. The project took just over 2 weeks as anticipated. We are thrilled with the patio and have been loving spending time in our new outdoor space and look forward to many more years of enjoying our outdoor space. (Just need new furniture next!)

After a rainstorm my 30+ year old 2nd floor deck started to sink. It was time to replace it.

I selected O'Keefe after getting four other bids. They were the most professional and were able to explain how the construction would make the deck safe.

They did encounter some weird issues during construction. Apparently the previous owner poured cement over an existing cement pad. That meant more work for the crew, but the additional charge was reasonable. Also, they discovered why the deck sank after the rainstorm. The previous support had been wet set into the concrete and over the years had succumbed to dry rot. They showed me how the new setting for the support would not be subject to that in the future.

There were a couple of minor issues with the fit and finish of some of the fascia and with some exposed sharp screws, but O'Keefe came right out and took care of them.

When the city came out to inspect the deck, the inspector remarked on the quality of the build and the sturdiness of the construction. That is what I want to hear from an inspector.

A week after construction (and the final payment) the powder-coated steel railing started to rust. O'Keefe got with their supplier and within a week or two the supplier had come out and replaced the railing. They even came back a second time since the railing they had installed had been damaged prior to installation. This showed me that O'Keefe is not looking to make their money and run, but that they stand behind their work.

O'Keefe was not the cheapest bid, but my experience has shown that the cheapest bid in the short term is often the more expensive one in the long term. I am confident that O'Keefe will stand by their work if anything should come up in the future and that the deck they built will last for decades to come.

We used O'Keefe Built to replace our old rotten deck. They were excellent at keeping in touch and I never had to worry that they were ripping us off. Felipe Gomez was the main man onsite and he was amazing. His work is wonderful and he is so easy to talk to and doesn't mind answering questions at all. I'm looking forward to hanging out on our new deck when our new furniture shows up! ;D

The entire O'Keefe Built experience from initial quote to finished product was top notch. Extremely professional operation with careful consideration for customer care and quality. Pat O'Keefe and his entire team helped us determine the best options for our new TimberTek deck, from size, elevation, and finishes. We had timely updates with the BuilderTrend app and from Chad, all questions were answered right away in great detail. The construction crew were fantastic, they kept the site very clean. Karcy even came out post build to make sure we were completely satisfied. We highly recommend O'Keefe Built and will use them in the future for our covered deck.

We recently completed an overhaul of our outdoor landscape at our home in Boulder, CO. We worked with O'Keefe Built to build a new fence and install decking near the pool. Pat and his team at O'Keefe Built completed these two elements of the project expertly and extremely efficiently even when battling weather elements during the winter. The quality of the fence and deck are of the highest standards and we could not be happier with the finished product. Even more importantly, Pat was excellent to work with and is extremely knowledgeable and professional. He's running a very organized business/operation. The project team of Chad, Mike, and Dayne was outstanding. They were extremely respectful of the space and very responsive to questions or concerns throughout the duration of the project. Their professionalism and craftsmanship were outstanding. I could not give a higher recommendation to O'Keefe Built and their entire team/organization.

O'Keefe did a really terrific job on building our deck! The previous one was old and dangerous and the one they put up looks incredible and is safe and solid. The whole process happened quickly and all the folks who worked on the job were super friendly and professional. They even helped me pull my truck out one day when I got it stuck in the snow! Really great company!

We worked with Pat O'Keefe to design and his team to construct an outdoor kitchen space. We kept the design simple with room for future expansion. Once the design was completed the work began. This is a completely custom build from the ground up. The team of folks who did the work were all professional, skilled friendly and technically proficient. Anytime there were questions they engaged quickly to resolve them. What impressed me most was the attention to detail. During each step of the construction the components dry fit to ensure everything fit as expected. There were no surprises at all during the build. I knew what to expect during the entire process. Thanks to Pat, Mike, Dayne, Caleb, Jerry and the others for a great job.

We had a great experience working with O'Keefe when we replaced our rickety wood deck with a composite deck. Pat was so helpful at the initial consult walking me through various products and how they hold up with Colorado weather. Everyone one on the team - Derek, Chad, Felipe, and Mike- were professional and friendly. They took the time to answer our questions and walk us through the process if anything arose. We love our new deck and highly recommend O'Keefe.

O’Keefe Built was so great to work with. After doing an extensive search for a deck contractor via NextDoor, Google, and other locations, we reached out to O’Keefe to provide a bid for our deck replacement project along with three other contractors. Although their bid was one of the highest that we received and their schedule was the farthest out, their professionalism, expertise, and responsiveness outweighed everything else and we decided to go with O’Keefe. These traits extended through the pre-construction and construction processes. Once construction started, the crew was super efficient (minus some weather and sickness-related delays which are understandable for a construction project scheduled in winter) and we were continually in awe of the high level of craftsmanship. They were super accommodating with our requests to impact our neighbors as little as possible regarding parking, the portapotty location, length of time the dumpster was on site, and removing their work trailer from the street when possible. Our new front and back decks are so structurally sound and look amazing. We cannot wait to use them when the weather warms up! Thank you for all of your hard work, O’Keefe Built!

We recently have a deck build and like the workmanship on it. The crew (Chris/Bailey), PM (Chad), Project (Pat) and sales (Derek) team are easy to work with and allows us the project to finish in time. With warranty of 2 DL/25 years Material and a solidly build deck, we feel satisfied.

Wow, we love our new O'Keefe Built back deck and front porch! They turned out even better than expected and the deck has changed the way we use our backyard. With the added privacy, we now use our new deck several times a week for dinner, instead of once a year. And our matching front porch completely modernizes the curb-appeal of our home. In fact, we only decided to add the front porch after seeing the quality of the back deck as it was being built.

If you are looking for a great value in decks, rather than the cheapest in town, O'Keefe is a great place to start shopping. What you get for a little extra money: 1) Engineered wood for the framing that starts straight and stays straight, unlike pressure-treated pine, 2) Top-level materials, with no shortcuts on hangers, flashings, railings, etc., and 3) Absolutely bomber construction, with 12” on-center joists, double and triple beams, etc., etc.

Felipe built our deck and porch by himself, and he’s one of the best craftsmen whom I’ve ever met. His work is impeccable and a joy to watch. From digging the first footer to mounting the final handrail, he clearly had everything planned from the start. He is truly a master deck builder and meticulous about the details. Everything was dead level and lined up perfectly. If you get Felipe assigned to your job, consider yourself especially fortunate.

Communications with Pat (the owner) and Chad and Derek (the project managers) were good from start to finish. All promises and expectations were delivered on, with no surprises.

Bottom line, we paid a little extra with O’Keefe and are really glad that we did. We have a beautiful deck and porch that will be a joy for years to come.

Our experience working with O'Keefe Built, which installed our new front steps and porch, couldn't have been more positive. When we first started working with Pat, he helped us narrow the selection down to exactly what would work best and look best for our space, making the process easy for us. Once the materials were selected and ordered, the project manager communicated regularly and professionally with us, to let us know the status and timing of the installation, and to take additional measurements. All steps that O'Keefe Built took were helpfully noted in the BuilderTrend app, for reference. The actual installation was on time, and expertly and efficiently done. We were extremely pleased with the detailed care and attention that the workmen and the project manager gave to the project: the project manager inspected the work after completion to make sure that it was done properly and that we were completely happy with it, and the carpenter himself wanted to fine-tune one or two details. We'll gladly work with O'Keefe Built again.

We were very pleased with all aspects of our project from bid to final product. As we were often away, having excellent communication with our project manager was essential to success. Very quickly we learned that we could trust the O’Keefe team to provide excellent advice and quality workmanship.

Jeff Simons

Working with Pat, Chad and the O'Keefe Built team was a real pleasure and the result is simply outstanding. They are true craftsman and they build to a level of detail that insured every aspect of our deck and patio was just perfect...absolutely no shortcuts. The construction site was cleaned at the end of each day and everyone we met was friendly and courteous. Communication was excellent and working through design changes along the way were easy. Their advice was always spot on. The entire project was well documented and finished right on budget - no surprises! I think the best recommendation is how many of our neighbors have admired and commented on our finished project and asked for Pat's contact information.

We have a small yard, and the builder left all the houses in the neighborhood with severe grading problems and accumulations of the residue from watering from houses "up the street." We had managed to fix some of that. Still, putting in a deck was going to have to deal with issues. We wanted a classy deck with some height and warmth (good materials and quality railings) to make the yard stand out, and give us an organization point to finish putting in shrubs and trees. Chad, the crew leader noted that our original choice for a stairs to the yard ended up hitting the lowest water coagulation point. He suggested several changes that added only a small cost, and ended up giving us a view to coordinating the yard better than what we first planned. Okeefbuilt was out to give us great looking, distinctive deck, one both the builder and we could be proud of. PS: Our neighbors were impressed that Chad introduced himself and explained what was intended when they started on the job and we were away. The phrase they used: "What a polite crew!"

I had Pat and his crew replace my old front deck. I've had work done on my place before and always cringed when watching the way some contractors did their work, knowing it was the quick and easy way - not the "correct" way. My back deck was recently replaced by the HOA and the stairs are already warping (6 months later) and it was a sloppy job all around. The front deck O`Keefe built is absolutely perfect and solid as a rock! I watched Pat's crew, Mike Lampp in particular, meticulously measure and re-measure every little angle and corner. I was so relieved to have chosen a company that cares about the quality of their work and has such an incredible work ethic. All of the guys on the crew were polite, extremely hard working, skilled and kept the work area neat and clean. I can't recommend them enough.
Thank you Pat, Mike, and the rest of the crew!!!

We are very happy with the work done by the O'Keefe crew. They were cheerful, responsive to our questions and needs, attentive, and COVID aware. The detailed work with the stairs was remarkable. The project manager was easy to work with and showed up on a regular basis to check on the work and our needs. The work took about a week or so. The deck looks very good.

We couldn't be happier with the way our project with O'Keefe Built turned out! We wanted a sturdy pergola that would be built to last for years to come to add shade and aesthetics to our backyard patio, and they certainly delivered. The entire team, from Pat (the owner) to the project manager, the carpenters, and the finishers were excellent to work with, communicated effectively, met deadlines, and were considerate to COVID precautions. We can't say enough great things about these guys!

Susan Traylor

I LOVE our new deck. As the deck was being built, I wanted to change the stairs and they did so without any problem. The crew was fantastic, very covid conscious, and they cleaned up after themselves every day. I would definitely recommend O'Keefe Built to anyone interested in adding a high quality deck to their home.

O'Keefe Built, Inc is an exceptionally fine resource for deck building, replacement and reconstruction. Patrick has complete integrity about the work, the costs for down payment and final payment. The carpenter he had on my job, Micah, built everything with consideration for aesthetics, safety, quality and durability. For example, all the nail or screw holes are perfectly aligned. Patrick and Micah were completely up too date on building codes, extremely helpful when we encountered problems that were outside their scope of work and gave me great support in dealing with those repairs. I can't make a higher recommendation than I do for O'Keefe built.

Through estimates and accurate schedules. Communicates well when there are possible increases in costs and provides options to stay on budget.

Pat and company replaced our deck and did an exceptional job. I especially appreciated how attentive and responsive he was. He took a lot of extra time and effort to make sure I understood the different materials and options, and that I was happy with the results. Any problems that came up he solved creatively and effectively. When I had called the references that he gave me, each one said something like, "Oh I give him eight stars out of five!" Add me to this eight stars category!

Patrick was very accommodating in helping my husband and I find an economical way to have a Trex deck built. He and his team were very courteous and went the extra mile to build a quality deck!

Pat worked with us on a tear down and expanded rebuild of our deck. Excellent to work with during planning and extremely pleased with the finished product.

The owner Pat is great to deal with. High quality work and takes the time to discuss many options and styles. Highly recommended if you're looking for a reputable company to expand your outdoor living with a deck and outdoor kitchen!

Terrible contractor. Bid a deck rebuilt for me. Refused to let my concrete guy pour the caissons. He did the caissons way under grade made a huge mess on the side of our house. Cut the steps off our deck. Then stopped answering my text and calls. When I threatened him with legal action he emailed my wife and said he wouldn't be back to finish the job cause he felt threatened. He did give me most of my deposit back minus $2600 for Caissons that I had to pay another contractor $2000 to redo them. Now he won't answer any calls or emails. He will ask for half down and 25% more if the job takes longer then 2 weeks. I checked at the home center and he never ordered our materials after 3 weeks. He quit the week he was suppose to start the project. I should of ran away when he told me a lady rated him low cause she didn't like the price. He will talk a big game how he does quality work and has integrity. BEWARE!!

So you won't warranty a caisson done by someone else but you will take direction from him? Sounds like a pretty weak excuse for bad work. I said they would pour the caissons for cheaper because they were already going to have a pump back there. The demo part was to move work along since i had no steps on my back door. Funny you never addressed taking money and never ordering supplies. Guess you overlooked that part. Why won't you be a man and call me back or answer a text? You have no integrity. You just use that to rip people off. FACE IT YOU GOT SPOOKED WHEN I SAID I WOULD SUE YOU FOR MY $11K BACK!

The best home improvement experience I’ve had. Excellent communication and work quality. I wish they did more as I have more projects I need done.

The O'Keefe crew rebuilt my front porch and back deck on my 1930's bungalow. Their craftsmanship is a thing of beauty. They were great to work with and I got exactly what I wanted. I would definitely recommend them.

I have used O'Keefe Built for 5 projects, some small and some larger. These folks are absolutely the best. First, they use an estimating tool and, unless I ask for extras, they are always spot on. I had a fantastic studio built for my craft business and it is beautiful! we had remodeling done on two different houses (bedrooms, and in one case the entire downstairs) and they turned out great! I have them working on another project right now which I am highly confident will be perfect. They do what they say and keep you informed as the projects go along. Having been a project/program manager for 25 years, I highly recommend them!!
