JK Contractors

JK Contractors were professional for the beginning to the end. I highly recommend them. They did my roof and excised my expectations. They were very clean and fast. I couldn’t even tell they were here when they completed the job.

I am a retired Builder, jk did my entire house of windows,did my daughter's house after a hail storm, I recommend him to a home owner I built for 30 years ago, and did work for our home owners association. Jk's family and workers are the best, all the workers have been with them for over 20 years,They go way beyond standard of the industry, you would be lucky to get them. Thanks Jk.

This is a great company! They did our entire house - roof - siding - soffits - gutters. It looks amazing! The attention to detail the by the team working on our house was impressive! I would highly recommend them if you need any exterior work on your home!

JK Contractors did an amazing job. They communicated very well with us and were super efficient. Every night they cleaned the worksite and asked us to look at their work and tell them if there were any changes we wanted to make. My wife and I were extremely happy with the final results of the project. Mitchell and Spencer were unbelievably amazing. Their crew worked hard and were very polite. The whole experience was smooth and easy. Extremely Happy.

WARNING: CAUTION HIRING JK CONTRACTORS

JK Contractors were hired for a comprehensive project including roof replacement due to water leaks, damage, mold, adding vents, replacing insulation and gutters, as well as adding additional structural supports. Initially, Jeff, the contractor, communicated effectively and professionally during the consultation and contract signing phases.

Unfortunately, after the contract was signed and the deposit given, delays in scheduling arose. It took weeks to schedule the actual work, causing inconvenience as arrangements had been made to accommodate the crew’s arrival.

The crew worked quickly but with little regard for property care, trampling the landscaping in the front yard and leaving the skylight covered in debris from the roof tear-off. Post-completion clean-up was subpar, with multiple pieces of shingles, nails, and insulation left strewn around the yard.

During the project, Jeff’s presence was minimal. The crew lead, who struggled with English, made real-time communication challenging, often directing us to contact Jeff via phone for any issues as he was limited in his ability to make decisions. This caused frustration and delays in addressing problems effectively.

Midway through the project, it was discovered that the crew began laying shingles on the old roof without replacing the OSB sheeting as agreed. Despite lengthy arguments, only the untouched half of the roof received the new sheeting.

We paid for mold treatment and insulation, but the crew failed to replace some of the old insulation, leading to the discovery of black mold remaining underneath. Continuous calls to Jeff during the project's duration were draining and time-consuming, highlighting a significant oversight and lack of thoroughness.

Additional ventilation installation to the bathroom was poorly executed. Long nails blocked the fan motor, rendering it inoperable. Furthermore, a metal sheet left over the fan prevented air from venting properly. After persistent disputes, Jeff returned to fix the issues, but the fan motor remained dead, which we had to replace ourselves.

The shingle installation, especially at the corners, was poorly done, indicating a lack of attention to detail and craftsmanship.

Based on our experience, we strongly urge potential customers to be cautious when considering JK Contractors. Despite initial good communication, the project was marred by delays, poor workmanship, communication challenges, and substandard practices. The constant supervision required and the need for follow-up on various issues were exhausting and unprofessional.

All work was paid in full but I will never recommend JK Contractors to anyone. Photos were taken of all of the issues noted above when they occurred.

Jeff and his team are awesome. I met him while he was doing a friend's house who met him.because the contractors doing her house had messed it up. Jeff was an amazing resource the eventually earned her trust as well as that job.
He then did my friends daughters house and then mine.
He is a cool confident partner. I would highly recommend him for any of the services he offers. The work is top notch, great communication, great workmen and workmanship. 10s all around!!!

JK Contractors is the worst contractor we ever hired. They were paid to replace our roof, INCLUDING all the OSB wood sheeting because of extensive mold. They tried to leave the worse part of the roof unchanged, and when I finally argued by phone with the owner Jeff he said it would do it on the remainder of the roof but wouldn't go back and replace the large section already neglected and shingled (and still covered in black mold). There was other very poor work done (installed fewer vents than we paid for, and very very poor spraying of mold killer they were paid to do. (which now had spread to the new sheeting from that lumber holding the roof up) We had to pay NARI $1,500 to take Jeff to arbitration. We settled before that before it got to the arbitrator. JC Cont. was forced to come back and remedy these and could not even do that right!! Jeff himself was here. He put in additional vents, but he never cut the hole if the roof for the vents! I believe that was a malicious act. Today, the roof has re-grown the mold. What a horrible experience. Really.... you can do better, avoid them like the plague!

J&k contractors are a must for any home renovations. Their diligent and thorough work is unmatched. The crew found ways to improve additional aspects of our house such as installing our ring doorbell in more visibility pleasing way. We are so happy and grateful for their hard work!!!!

SAVE YOURSELF THE TROUBLE! The one star reviews on here explain exactly everything we went through. Once we signed the contract, it took weeks before the job was done. Communication only exists if you are reaching out about money. Besides that, he’ll give you short response with no action step. At times, he just straight up did not respond. Very unreliable! He also did my gutter, which is leaking now. I have reached out but now he’s ghosted me. Roof looks okay, siding looks fine. But in the process of doing my roof, they broke through my ceiling, which took another 1.5 weeks before they came in to do anything about it. The repair job was very amateur and I am now having to repair it myself. Took out our deck and left a mess a nails for us to find. There were nails from the deck as big as your thumb in my backyard. Seriously… save yourself the headache and move along. You’ve been warned.

Jeff and his crew has done several jobs for use . We have always been in communication with them and never surprised by any thing Great good guys once again.

Dukes Roofing

Fantastic experience having new siding installed. The crew was very professional and worked so hard - most days they didn’t leave until dark and the first week they worked 11 hours days Monday thru Saturday!! The house looks beautiful. Highly recommend JK Contractors.

Jeff is great. They helped us replace our dated cedar roof with a great new roof and gutters. We continue to be complimented by neighbors and would recommend Jeff for all home exterior projects. Also a great referral by Neu’s Hardware.
Thanks again, Dan

From beginning to end working with JK Contractors was exceptional! Jeff and his son's, Mitchell and Spencer are incredibly knowledgeable and have an extreme sense of pride in their work. They take the time to stay educated on the materials they use to ensure the job is done correctly and to perfection. Their attention to detail was so greatly appreciated. They completed all aspects of the job with meticulous care, from the start of the job through clean-up. They tore off our old aluminum siding, gutters, facia and soffits and replaced with LP siding, new gutters, facia and soffits. Their crew was wonderful to work with and we cannot recommend them enough!

It’s been 1 year since JK contractors completed our siding and windows and we are extremely satisfied with the outcome. Jeff is not an insurance storm chaser looking for easy insurance money, he is a craftsman who has perfected his craft. He came in quick (when we were having troubles with a different contractor) and gave us an old school hand written estimate. Just a short time later (after they had all the materials) they came in and completed the job within two weeks. Awesome crew and awesome work! Thanks again Jeff!

JK Contractors just put a new roof and gutters on our home. They were very responsive to all of our questions. They got us on their calendar quickly and I was blown away by how quickly they completed the job. They didn't bat an eye when unexpected rot was discovered where our old gutters had failed. Our property was clean when they left. We had follow up questions after the job was complete and they immediately got back to us. I highly recommend JK Contractors.

We hired JK Contractors to replace the siding and gutters on our home. The crews that did the work did a great job. They were professional and have a great work ethic. The communication and any questions for the office and Jeff were always answered promptly. You won’t be disappointed!!!

JK Contractors were hired to replace our roof. We were able to get a quote and a start date established quickly which was great since the roof of our house we had just bought was in bad shape. They not only replaced our roof but also ended up replacing our gutters as well. They did a great job on both tasks. The crew was able to complete the job in one day and left the property clean and safe. We are incredibly satisfied with their work and will be reaching out in the future for any other repairs we might need. Thanks to Jeff and his team!

Kudos to Jeff and his crew,,,, they did an impeccable job for me. I had 16 windows installed and they did it expeditiously and cleaned up after, I didn't even know they were there.They went above and beyond including but not limited to putting my window air conditioners back in place and their pricing was better than fair,,,,they were heaven sent. Donna

JK did an amazing job on my house after it had severe damage from a hail storm. It took longer than I liked, but that was due to material delays, and was not their fault. I pretty much had the entire exterior of my home redone and I couldn’t be happier with the quality of their work. I would recommend them to anyone.

JK Contractors delivers fantastic service and quality results! Our house received a complete update with siding, roofing, fascia, soffit and gutters. Mitchell worked with us and talked about our project as passionately as it was his own. His eye for the details that go into a project such as this are excellent and we were lucky to have him work on our house. The whole team at JK worked hard on our home and we could not be happier with how it turned out!

I was quoted and signed for a small $1600 repair job at my house in December '22 with JK Contractors. I was told 4 separate times that the work would be done within the next couple weeks. I ultimately canceled my work with them in June '23 since they never showed up to do the work.

From the time of the consultation to the finish of the job 8 days later, it was a pleasure working with JK Contractors. A highly professional team that worked fast and worked hard. Communication was constant and responsive. I will utilize this company for all of my needs from here on out. 5 Star Service!!!!

I called JK Contractors for a patio door installation. I "worked" with them for 9 weeks, starting in February. Communication was terrible, but given the demand in the industry, we gave him the benefit of the doubt (our mistake). We never got a door ordered or an installation date. Such a waste of time.

Jeff came over twice, once for the initial consultation and once to get a us a sketch to pull a permit - that was March 2022. Still have not heard a word from them (currently mid May). Mind you, he had sent an estimate prior to the second visit and wanted $1500 down with no secured permit.

On that initial consultation, he told us we had to move an air duct and an outlet would have to be moved. Within 2 weeks, we had the duct moved. The outlet he told me not to worry about even getting anyone in prior to install as they wouldn't be able to tell us anything until they're in the wall. Then during the second visit for the sketch permit, right when walking in the door and upon seeing the new air duct, the first thing Jeff says is, "I wouldn't have put it there." He gave us no insight or no indication of where to put it prior nor had his own subcontractor to coordinate the plan, so I trusted our HVAC professionals to make that assessment. Then he proceeds to ask, "who's your electrician, that outlet needs to be moved before we can do anything." As stated above, that is not what he initially told us. He treated us as if we knew what we were doing and then belittled us for not knowing the ins and outs or removing an exterior wall and putting in a door. If we knew anything about this project, we wouldn't be hiring you for $5k+ to do it.

From start to finish, communication was lacking, what he did tell us was contradicting, and he was just flat out rude. Don't waste your time or money. Given the lead times on these projects, I'd have my project done by now had I started the process with someone else.

Replaced my garage roof and some rotted sheathing. Also covered all trim with aluminum. Great crew did a great job. This is why I’m a repeat customer.

We used JK for new windows, gutters and siding. We were very pleased with the professionalism from the staff and the final result. Highly recommend.

Rock stars! We recently had our roof, gutters and siding replaced by JK Contractors and could not be happier. They were professional, timely, knowledgeable and patient with us. Their attention to detail was above and beyond and the finished work far exceeded our expectations. We would definitely recommend JK Contractors.

Jeff and his entire team were amazing! I cannot say enough good things. They were hard working, efficient, detailed, great people and very importantly …considerate of my flower beds. They went above and beyond paying attention to every detail that could make our roof look as fantastic as possible! And it does!

Came in discussed what they could do,. Luckily were able to come in and get the job of residing my home's rear wall in a single day for a fair price.

JK contractors replaced 9 basement windows in our 100 year old home. The glass block replacements look beautiful. His crew was timely, efficient and a pleasure to work with. The job site was cleaned up nicely. This company definitely deserves a 5 star rating.

Roof, siding, porch, insulation and new windows were installed by the JK team, including tear off of old materials. About a dozen homes in our neighborhood have used them, and everyone sings their praises. We, too, could not have been happier. This team worked fast, were tidy, quiet and and professional- project managers on site working with the crew every day were quick to update us on progress and address questions that arose.

They book out quite a ways, and are not as quick as others to return initial outreach, but once your scheduled and your work begins, they are extremely attentive to your project and needs. Worth every penny, have recommended them to others, and would absolutely use them again.

Siding, trim, facia and soffit replaced. New gutters and sky light. Superior workmanship with attention to detail. Job completed timely and thorough cleanup each day after completion. Well organized and promises kept. Highly recommended--

Installed all new windows on my house. All questions were answered and the crew was timely and professional. Could not have asked for a better product or service.

We used JK Contractors for siding, roof and gutter replacement. The entire crew was professional and courteous and their craftsmanship was exceptional. We would highly recommend their services!

JK has done roofing for me, gutters, trim, and even cut in a skylight. Outstanding service and workmanship and above all very neat and clean. Highly recommended

We had our windows replaced and they did a wonderful job! So nice and friendly. They even worked in the rain and got everything done quickly.
Highly recommend! Will use again for other projects!

J&K did a fantastic job on my roof, gutters, and siding! Great attention to detail and quality was outstanding. The house looks better than new. They are very conscientious about cleaning up too. No regets going thru J&K.

Hired to replace my siding. After signing the contract it took another 8 months to start the project. I understood the material delays etc so waited patiently. Well just found out the left my air conditioner wires exposed and sides over the drain pipe for the unit. I informed Jeff and his response was well my apologies. Horrible experience!

I called once and didn't receive a professional response. No 'JK Construction, how can I help you?' or anything along those lines. I told him what kind of work I was looking for and he responded he is busy, can he call back in 5 minutes and asked would i be available.
I told him I was and I never received a call.

I've already dealt with someone like that at another construction company for another project and didn't receive the best experience or finished product. I'm not going through that again. If they don't have the time to call me back and be professional, they won't give my project the time or professional care.

I may be strong on this issue, but my money is too valuable to waste.

Great company to work with. I called them for a repair for my front fascia that was ripped off in a wind storm, and they were at my house within a few hours of calling.

Looks great, and no problem since with the high wind in my area.

Highly recommended!

Do not take the risk - hire another contractor!

JK Contractors destroyed my near new roof when they installed gutters, cracking or tearing every shingle on the roof perimeter, often going up several shingles.

Instead of cutting off the old gutters (per contract) they were torn/ripped off, taking the ice and water shield with them. Many times before and on the day of installation I asked and owner Jeff confirmed absolutely no harm would come to my roof - he lied - repeatedly.

It’s hard for the untrained eye to see, though a roofing contractor and owner of a 41-year company would have recognized it immediately, my roofer confirmed.

He knew, did nothing about it, and a year passed before I noticed - I’ve been living in a now likely water damaged home for a year! I may have been exposed to the mycotoxins from mold - a carcinogen! The house smells like wet wood.

Within just three hours of posting on NextDoor to see if others had similar experiences, three responded with nightmare stories: flooded homes, rotted wood, leaks, water damage, mold - in all those cases as in mine, he never responded to their calls and emails for him to correct a major problem or reimburse for expenses and loss/damages.

I have filed a claim directly with his insurance, Frankenmuth, and recommend others who have similar problems do the same. I am also preparing a lawsuit to file for damages the insurance company doesn’t cover.

Save yourself the time and misery. Find someone else! Perhaps he does better work on occasion, maybe for larger jobs, but several homeowners Had a horrible experience.

We used JK contractors for a new roof, siding, facia, soffit, gutters and insulation. Eric our salesman was very helpful explaining each material option and answering all our questions. The entire crew was very professional . They went above and beyond our expectations. We would highly recommend using them for you exterior project.

We were not familiar with JK Contractors until this summer when we saw them do a roof on a home on our street. The roof was completed in one day with a great crew. We met with Jeff who went all around our house and even looked into the attic to see our insulation. We were impressed with his thorough proposal for the roof and because we felt so comfortable that he would do a great job, were decided to replace our siding as well. And as long as we were making our house maintenance free, we asked him to redo our decks. Jeff has a team of craftsmen who really care about their work. We were amazed at all they did. They created a beautiful pillar for our porch and designed a decorative post for the front of our house. They worked hard even in the hottest days of this summer. They are a crew who are knowledgeable , friendly and professional. The roof, insulation, soffits, rain gutters, siding, downspouts, and the decks were completed in 8 days.They did a fantastic job!! There many features we were not expecting which added so much to the appearance of the house. The work they did really far exceeded our expectations!!Jeff and his crew went above and beyond! We love our "new house"> We have received so many compliments about how beautiful our house looks. We highly recommend JKContractors!!!
We would give them 6 stars if we could!!!!

JK Contractors replaced the siding on my house with HardiePlank. The whole process with Jeff was professional from the initial walk around to the quote to getting the job scheduled after the siding arrived from the factory. The installation crew was exceptional, highly skilled, friendly, and professional. The entire project was completed in 2 days. The siding looks great. My concrete foundation is exposed above the grade about a foot. Jeff suggested to cover the exposed foundation with aluminum trim that matched the siding. Mitch did an awesome job doing the actual work. The result makes house look a million times better.

Thankful and grateful JK Contractors could get our roof project completed...after getting the run around from other company’s we reached out to JK and the work was done quickly, efficiently and very cleanly! Their crew was professional, on time and our new roof and gutters are beautiful and exactly what we ordered/expected. Would encourage others to use JK Contractors!

We had a fantastic experience with JK contractors. Jeff and crew are knowledgeable, honest, and reasonably priced. We had full a roof tear off and replace and all new gutters installed. We received quality product and installation,; both of which are backed by substantial warranties. Communication with Jeff was fantastic both before and during the project. The crew was hardworking, pleasant, conscientious around the landscaping, and the clean up was absolutely impressive. We are so glad with went with JK after talking with another "roofing" company that was more concerned with insurance checks than with providing us with a quality product/install. We highly recommend JK and will be using them again for siding in the future. Thank you!

JK Contractors tore off our old roof and gutters and put a new roof and new gutters on in one day. They used quality Owens Corning shingles. It looks so much nicer that the old roof. Jeff told me that the venting in our attic was not good, so his team also installed ridge vents to extend the roof life mold growing in a few spots on our ceiling in the winter. They also sealed very well around our chimney and skylights. I am very pleased with their work!

I chose JK Contractors to replace the roof on my house for several reasons. First, the price. I got quality materials and installation at a fair price. Second, they are a member of NARI which indicates a certain level of professionalism. And third, they send an efficient crew of men who were able to tear off, replace, and clean up in one day. I highly recommend JK Contractors!

JK Contractors conducted a thorough roof inspection on our investment property and got us a quote in less than 48 hours at a fair price. JK Contractors came highly recommended from our home inspector for their professionalism and work quality. I will definitely be using JK contractors in the future.

JK Contractors did an excellent job with our new roof , gutters, and Hardie siding. The work crews were courteous, good tradesmen, and left our property immaculate. We received a lot of compliments about how nice our house looks, and the speed and efficiency of the crews. They were also very well supervised. We waited 15 months until JK was available, and I'm glad that we were patient. It was worth the wait. JK Contractors is head and shoulders above their competition. Excellent!

Our new roof looks great! The crew was super conscientious about our stuff and the clean up was stellar. The showed up on time and worked hard to finish in 1.5 days. Great communication on any issues or questions as the roof was being put on. We love to support local companies and JK Contractors is one we will call on again if the need arises. Thank you!

Karl Norris in JK Contractors replaced a couple of rubber boots on the roof and it was a very pleasant experience for me. Highly recommended!

New gutters & soffit. Replaced original (30 + year old). Well done, thorough attention to detail, efficicient, well executed process.

Noticed a roof leak last night, called in the morning and it was fixed by 12:30pm. Couldn't be more thankful. Call JK for your roof!

Working with JK Contractors was nothing short of phenomenal from start to finish. I called to set up an estimate, and within a 24 hr span, I had someone come out, give my home a thorough inspection and estimate, and a signed contract for work. Although they had a lot of work lined up, they were able to prioritize my job, being that I had a hole in my roof leaking into my attic. When they started, they tore off 2 layers of old roofing and installed a brand new roof in ONE DAY. My roof is approximately 2,100 square feet with multiple levels, so I was extremely impressed in their quick work, and also maintaining an extremely high-quality appearance. They were respectful, prompt, and responsive from start to finish in the process. I would absolutely recommend JK Contractors for anyone needing work done on their home.

JK Contractors replaced a leaking rubber roof and installed a new Azek deck and railing. Provided a prompt estimate and completed the project in 3 days. Arrived on time and cleaned up the site after each day’s work. Did everything as promised. Very professional job and timely responses to all questions.

Highly recommend Jeff and his crew. They were timely with providing a quote for our roofing and gutter needs, as well as scheduling the work once we made our final decisions. We will definitely be using them again for future home repairs!

I highly recommend JK Contractors. I had my siding replaced with Hardie Board and they did a fantastic job. I cannot say enough about working with Jeff and his Crew. They were amazing; each and every one of them were friendly and very hard workers. The job site was clean every night before they left. Also, after meeting with multiple contractors, Jeff was the only one that took the time to ask questions about my house and offered solutions to improve it. Awesome job Jeff and Crew! Thanks for everything!!!

They completed an estimate but never came to do the work. I called repeatedly to get a date on the calendar and couldn't. They didn't return messages and stopped answering my calls. We got another company to do the work. If it's not a huge dollar job they won't do it!

Jeff and everyone at JK Contractors did an awesome job on our roof, soffit, facia, and gutters. They wanted the job to be done right and did fixes for reasonable prices. Support your local small/family business and go with JK Contractors!

Professional, prompt, knowledgeable- JK Contractors carefully restored our home (removed siding, wrapped and insulated, re-sided and put on a new flat roof) in under two weeks. The crew members are fast and clean with positive and proactive attitudes.
I recommend JK Contractors without reservation.

JK Contractors did an amazing job.
They were able to identify the issue, provide recommendation on how to correct the problem and completed all work in one day. I can’t express how happy and pleased we were with the result.

We recently used JK to replace our gutters and add aluminum soffits. The crew was on-time, very professional and did a great job with the install. The foreman walked around the house with me before and after the job and answered all questions. Jeff then contacted us that night to ensure that everything went well. The cleanup was very thorough and complete. I would use or recommend them in the future.

Jeff and his crew just finished siding our home in Menomonee Falls. His team (14 people on site) were all respectful and professional. Jeff, himself, was on site everyday.

JK exceeded our expectations. He framed the windows in a wider trim than we expected, just like those in the new homes. We have a gas line that runs on the exterior. They painted the pipe the exact same color as the trim. It virtually disappeared from view. After the old
siding was torn off, the crew temporarily reconnected the cable line so we would have internet for the night. We did not ask them to do this. When the job was done, they had permanently hid the cable under the siding.

These are all indicators Jeff and his team care about our homes. We highly recommend these guys.

Oh, they were must lower costs than the national companies advertising on TV.

Jeff convinced us to go with the hardie board (cement fiber). Very high quality.

Thanks JK.

Professional and personable from estimate to completion. The crew was on time and took great care in protecting my property and that of my neighbors. The clean up afterwards was amazing. I even requested an estimate for a additional project that was also completed with great satisfaction. Love my new roof and siding!
Thanks JK!

I shopped around for awhile, once I got a quote from JK Contractors it was on the lower end and from step one till the end they stayed in touch, were extremely professional and got the job done a day early, which I’m sure was not easy with a whole new roof and sideing. Keep up the good work guys!

We badly needed new gutters. I am so happy we went this this company. I actually looked forward to the rain and April snow (not really). It's great to have no more worries about water drainage or ineffective gutters and downspouts. They addressed every corner of the house and did the work efficiently. It's nice coming home to a house I'm proud to look at. Money well spent.

We were Impressed with the remarkable efficiency and skill with which JK Contactors replaced our roof. Although our home is quite large, the entire job, including gutter replacement, took less than a week to complete. The new roof looks great. Plus, the owner of JK Contractors is honest, fair and great to work with I highly recommend JK Contractors.

JK Contrators just installed a new roof on my home. They were fabulous. The crew was very professional with quality work. They cleaned up the whole area better than when they came. On a scale of 1 to 10 they are a 10.5. I highly recommend this whole crew.

Thanks for making it out here right after the horrendous winds, and thank you to the crew for taking on the work in the cold weather with a smile. Jeff explained everything and followed up afterwards. They know their stuff and gave us huge peace of mind

JK CONTRACTORS , CREW AND OWNER JEFF KURZ .Did a beautiful job on our house and garage roofs total tear -off .with excellent clean-up the color on the shingles match perfectly with our brick home.we will definitely hire Jk contractors in the future for another project.
