We hired CNW for a sheetrock repair and had such a positive experience later called them back to help us with a total kitchen remodel. An amazing and talented crew; thoughtful, timely, solid construction, creative with building solutions, easy to work with, and always left the site tidy at the end of the day. Highly recommend!

Read and his team are fantastic—great to work with and deliver high quality work. They built a stair, added a new railing and water drainage system onto our deck in 2 weeks—just in time for our party where they got good use. Several folx have commented on the high quality of their work when seeing the deck. Highly recommend this company for deck projects!

This is a great crew to work with. They remodeled many areas of our home and impressively did so without subcontractors.
They are very tidy and they returned their working area to a cleaned state at the end of each day, including the exterior. It is a skilled group that is flexible and communicative. There was no wasted time - they reliably work according to a schedule.
Before and after photos are included of the facade remodel.

We are really pleased with the work Read and his crew did on our house. They are professional, kind, and very communicative. I knew what was going on every step of the process and they worked fastly and efficiently. I felt I could really count on them to get the job done well and to show up every day bright and early ready to go. They were also open to feedback and last minute changes that came up. They handled any surprise complications with ease. This is so different from our prior experiences with other contractors. Definitely get in touch for your home project, you won’t be disappointed! Thank you Read, Geri, Miguel, and Andrew!

Read and his crew did a great job on our siding project. When they found there was no sheathing underneath our damaged siding, they engineered a solution that wouldn't affect the look of the house and worked with me to find ways to limit the extra cost. I'd work with them again.

Read and his team did a great job on our basement bathroom. They communicated clearly throughout the project, so we always knew what to expect. Overall, we’re very happy with how everything turned out!

We had a great experience working with Read and his team on our basement bathroom. They were easy to work with and the workmanship was great. We’re thrilled with how they brought our vision to life!

We're so happy with Constant Northwest Construction Services, we remodeled down from the studs in our split home, the basement had a flood from our water heater. The crew's work was amazing, they were very responsive to our needs, was easy to work with, and each and every day we saw progress. We've heard horror stories from other construction companies, but Read's team is amazing and he did great coordination with the plumbers and electricians. Read's crew does everything in including drywall, floor install, bathroom remodel. They do practically every renovation with exceptional work, I recommend them with your future renovations.

Last spring, our hot water tank failed, leading to our entire basement being flooded. The basement had to be gutted, giving us a blank slate to work with. I had a vision of what I wanted, and Read and his team brought it to life. Read made my various ideas a reality and even handled electrical and plumbing work that would typically be subcontracted.

A big shoutout to the team for their amazing work! They are professional, detail oriented, and easy to work with. The craftsmanship is top-notch, and I’m thrilled with the finished product!

Read, Andrew and Gerry were great guys to work with. I had them out to repair some rodent trim damage too high for me to reach along with an another decaying fascia board. Read gave me a clear and fair estimate, the guys showed up on time, we talked through the project, and they had it done quickly. Look forward to having these guys out in the future!

Please be cautious with this company. They attempted to overcharge us by tens of thousands of dollars and only after vigorously pushing back and providing proof of our own records did they back down admitting their bad accounting practices. At the end they did not complete the work but haggled over final payment. Read was incredibly nonresponsive and rarely present at the job site leaving much of the project management to us as the homeowners. This means that significant errors were made requiring re-work and additional expense and time for the project. Also, his team took advantage that I worked from home interrupting my work day constantly with questions that he should have handled / managed. The experience was very poor and I would not recommend this company.

We had an great experience with Read Constant rebuilding our deck. He was incredibly easy to work with, an excellent communicator, worked with us to stay in a budget that was comfortable for us and just made the whole process smooth!

My pipes burst last winter and did extensive damage to my home. Reed and Team did a wonderful job repairing and renovating. They are very trustworthy. His tile guys do amazing quality work. I highly recommend him.

I recently hired Read and his team for a home remodel, and the results exceeded my expectations. They expertly removed popcorn ceilings, installed luxury vinyl plank flooring, and transformed the staircase with beautiful stair treads and crisp white risers. They also completed a partial kitchen remodel, adding a gorgeous backsplash, butcher block countertops, and a modern sink. The project was topped off with fresh paint, new light fixtures, and curtain rods, perfectly bringing my vision to life.

Despite encountering more significant challenges, like a cracked floor, Read managed the entire project smoothly and finished within the estimated time. He communicated thoroughly at each stage, kept me informed on progress and any updates, and honored our agreed-upon budget.

I highly recommend Read and his team for any renovation needs—they’re skilled, reliable, and truly professional. I look forward to working with them again on future projects!

Read and team helped us restart our stalled kitchen remodel. We had the "easy" stuff done (holes in walls, tile removed, etc.) and we were ready to patch everything up and install the finishing touches. Except "we" couldn't do it, so we got professionals.
Read got his team lined out and every single task came in on time and on budget.
Plus it looks great!
We were putting together a list of our remaining projects and asked Read if he could do any of them. "Of course we can do that" to almost every item. And if he can't, he'll help find the right people for the job.
Constant North West construction really helped us out, and we look forward to working with them in the future.

Never had a contractor that communicated as well as Reed did. Great job on the exterior painting job, including fixing rot and replacing siding and making paint recommendations. His crew got the job done on-time, adjusted on the fly when needed, and they were neat and tidy. Highly recommend Constant NW.

Read’s painter did a great job on our deck, on time and as expected. The stain they selected seems perfect for a deck, water beads up on the surface nicely. Very happy.

Our small upstairs deck re-do turned into a much more extensive project when Read discovered water damage and rot due to poor drainage from the old deck. That entire corner of the house needed to be torn apart and rebuilt, with frequent consultation and careful planning. Read’s team showed up early, worked hard, and were always considerate. We’re delighted with the results!

Read and his team were wonderful to work with as we remodeled after water damage. They were prompt, paid amazing attention to detail, had great communication, and delivered top-notch work. I highly recommend them for any remodel work you may have.

From start to finish Reid and his team are great to work with!
Professional, easy to work with, clear and timely communication, dependable, quality workmanship; he definitely takes pride in his work and his team is so nice to work with.
Great problem solving skills as well.
They started on time, finished on time and I’m thrilled with the project!
I would not hesitate to recommend them!

Constant Northwest did an amazing job on our kitchen remodel! Read walked us through each step and explained to us what needed to be done and why. Read and his team were very professional, communicative, reliable and well priced in comparison to other contractors we received quotes from. We are so happy with the results and definitely recommend Read for any remodel needs! Our building’s
HOA President already reached out to them for a bathroom remodel :)

Also, we had an issue almost 2 months after completion and Read came by the same day and sorted it out quickly. Turns out we just needed a new dishwasher but Read was available to help and answer our questions. Wonderful customer service during and after our project!! We can’t recommend Read and his team enough!!

Two of my neighbors highly recommended Constant Northwest and, after completing two bathroom and 1 deck remodels, I fully agree with their recommendations. Read and his brother listened, worked through the project details with me, made adjustments I requested as the projects progressed , completed the projects on time and within budget, and I’m very happy with the results.

Read and his team were fantastic.

We had a challenging problem with a gutter, fascia, and roof repair on a section of an older house that a few contractors could not do or recommended replacing the entire roof unnecessarily. His proposed solution worked elegantly.

Great work, work ethic, and came in under budget(!).

All-around top-notch experience end to end. Read was referred to me from a neighborhood site. I required a GC to bid on work incorrectly performed and not completed by a previous GC. Read is knowledgeable, fair, provided a reasonable estimate and adjusted for unidentified issues as the job progressed. His team is professional and quick yet precise and efficient. Read kept me informed the entire project and final charge was below estimated quote. I plan to hire Read for additional work on my home.

Rick Nelson

I had a really ugly splotch on the ceiling of my garage. It looked gross and expensive and appeared to be growing.

Read stopped over and looked at it and proposed a plan. What had to be done was surprising, but Read was in charge and had the problem resolved quite quicky and expertly.

Read is a pleasure to work with and I cannot thank him enough for his planning, communications, and great work ethic. I cannot recommend his company more and will definitely use them for future projects.

Constant Construction finished our basement for us in March 2024, and I cannot recommend them highly enough! Read and his team were incredibly quick, thorough, and did a beautiful job, down to the finishing touches. Read always put our preferences first, but he was also consultative throughout the entire process to ensure we understood costs, timelines, etc. and would be happy with the final result. We were very satisfied with the overall cost of the project, especially because their work exceeded our expectations. We’re sincerely grateful to Read and his team for making our old little house even better for our family! They will be the first people we call if we have another house project to complete.

Read and his team crushed our full kitchen remodel. They were very fairly priced and communication was awesome. They even went the extra mile and did some extra electric work. Couldn’t be happier with our new kitchen.

Read did a terrific job for our house. He has worked on two different projects for us, six months apart: remodeling our master bathroom down to the studs and a lighter remodel on our kitchen. The bathroom project involved demo, drywall, plumbing, waterproofing for a new walk-in shower, tiling, and electrical. The kitchen involved repainting cabinets, plumbing, electrical, HVAC (new range hood), tiling, and regrouting (and tons of other skills I'm probably forgetting). There wasn't any task that Read wasn't capable of providing.

For both jobs, Read and his team were professional, high-quality, reliable, friendly, communicative, and reasonably priced. We were provided with detailed quotes that were spot on, and timelines that were fair given the complexity of the jobs. His work is top quality and beautiful, and we are extremely happy with the finished products. Highly recommended!

What was once a useless and unfinished outdoor storage area off our bedroom became a beautiful, fully finished walk in closet.
Our bedroom was in desperate need of a way to organize and store clothes and shoes and we are SO pleased with the results. Constant Construction was consultative, communicative and reasonably priced. Read and Luke really listened to what we wanted and made recommendations on how to make the most of the space. Their work was well done and they patiently explained each step of what they were doing. They were also prompt and finished the work quickly but maintained high quality in everything they did. Ciara was a fantastic resource to run ideas off of - paint color, flooring and organization ideas. Would highly recommend them and will definitely use again when we need other work done!

Constant NW did a fence and gate for us. Fantastic job, fast and reliable. Read worked with us on the design too.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
