Construction Company reviews in Tonawanda, New York

I needed to raise a corner on my front porch. Called JMK and they were prompt with scheduling the project. Staff was very easy to communicate with. Most importantly, my house looks great. Very, very happy with their work. I will definitely be a return customer for any project big/small.

We had a small bathroom that needed redone. JMK took the job and I’m so glad they did. The quality of work was outstanding. This is JMK’s second job for us. The first was our porch. Again, remarkable workmanship. I would bring them in again when something else needs dome. JMK will be my only call!

It has been raining for 4 days straight and my garage is desert status. These guys are by no means the cheapest and it takes a while from booking to actual work. And that's OK. They're busy because they're good. 5 stars. Hell, 10 stars.

JMK replaced my front sidewalk and driveway apron- they were prompt, professional and did an amazing job! I decided to have JMK do the concrete work over other contractors because they were reasonably priced and I felt comfortable to speak with the owner and crew about any concerns. I just ended up not having any concerns! 👍

I have had JMK complete 2 projects and are scheduling a third due to the high level of satisfaction I have with this company. Work is done at a fair price and with a high level of craftsmanship.

JMK fixed the drainage in our yard and were a pleasure to do business with every step of the way. John has a fantastic team! Because of new construction, they had to work in stages. We were impressed that they were able to fit us in with very short notice to get us through the first phase. Adam and his crew went above and beyond, were friendly and efficient!! And when they were finished, the yard was left in great shape with clean, neat lines where the pipe was laid. These guys are the best. I am going to call JMK for all of our future projects.

This company is without a doubt, the best to work with It’s so nice to have the peace of mind that my sump pump won’t back up anymore. I wish I could give this company 10 stars they made everything quick and easy

JMK showed up when they said they would, started and completed a porch and sidewalk tear out and replacement in 3 consecutive days! The crew was polite, friendly, and clean. Highly recommended.

They did a great job repairing the drainage issue from a previous driveway install (the drain problem was not JMK but a different company). The workers were all so polite and were very tidy after the work was complete. I highly recommend JMK, and I will definatley be a repeat customer when needs arise. Thank you for the great work!

Edward and Murnita Bennett we just had our driveway done by JMK what a beautiful job great customer service. We had black top changed to concrete. We are so happy with the results of a professional job . The came when they said they would and finished on time .

JMK is amazing! From the owner John making sure he was detailed with the plan and having the crew here when he said. The crew was also amazing. Adam ran his crew great. They were here everyday working hard letting me know each morning the goal for the day and hitting that or exceeding the goal. They were all very professional and nice!! The workmanship was top notch!! I would highly recommend JMK for all yours needs. They did my basement, putting in drain tile and a sump pump. Couldn’t be happier!!!!

John and his crew at JMK Construction were a pleasure the work with. They did an excellent job replacing our garage pad and front and side concrete steps. The crew worked hard, cleaned up every day, and clearly take pride in their work. John communicated clearly and promptly throughout the project.

JMK has done several concrete and drain tile projects for me, and every time they crush it. On time, professional, and flawless work that lasts. No shortcuts, no hassle—just the best results. If you want the best, you call JMK.

3 words. Worth. The. Wait.

John and his team did a phenomenal job on this massive driveway/patio project for me. I truly could not be happier with these results. Not only was their craftsmanship top notch but so was the customer service. John picked up on the first ring or texted me back immediately any time I reached out with questions. I'll definitely be calling these guys for any future projects!

I highly recommend JMK construction. John and his crew are all top notch people. I had my front porch redone, all new concrete walkway, stairs, pad and vinyl railings and could not be happier. Went from a front porch that was ugly and unsafe to something that looks A+. John is very responsive and will keep you informed at every step of the project. When John says his guys will be there at a specific date and time, they are there. He is always available for any questions or concerns you might have as well. His employees are very skilled and friendly, and I enjoyed talking with them every day they were here. At the end of the project they made sure to clean everything up beyond what even my expectations were, without me even asking. It’s hard to find a reputable contractor, but I’m sure glad I’ve found JMK 👍🏻

Thank you so much to John and his team. They removed our porch and walkway then replaced it with a new stoop and walkway They were very polite, professional and neat throughout the whole process, they were even done way ahead of schedule. I would highly recommend using them for your next project.

I have worked with JMK on four projects (front door stairs, driveway, downstairs bathroom/laundry room, and drainage throughout my house). They are without question the best construction team I have ever worked with.
John, the owner, is honest and thoughtful with his designs for the projects. There is no upselling or pressure. Just honesty and integrity.
I have interacted with several of his crews and project managers (Jordan-driveway, Adam-drainage, Nick-bathroom/laundry). They are hardworking and proud of the work they do (and they should be). Every crew member is friendly and skilled at what they do.

They are careful of your home and want to leave it in the best condition.
And the final result speaks for itself. JMK has made our house truly beautiful and I would recommend them to anyone who is thinking about a project.

We just had a new patio installed, and working with JMK has been a wonderful experience. The entire team is very knowledgeable and pleasant to work with. They had us come out and check all the forms while they set up to make sure everything was perfect. Follow up was great - John made sure the outcome was as we expected and answered all of our questions along the way. We highly recommend JMK!

Couldn't have asked for a better job and crew for our new drainage and bubbler system! The guys were hardworking, respectful and took care of my property like it was their own. It was neat even when they had it torn up! The new system works great and can already tell our water problems are solved! I highly recommend JMK for whatever you need!
Thanks again for the great work guys!

I worked with John Keller and his team to replace my blacktop driveway with concrete. It was a big project as I have quite a bit of driveway. I was nervous but I needn't have been. The professionalism and talent of John's team was above and beyond anything I could have hoped for. It was fascinating to watch this group of individuals make magic happen. Precision, knowledge, talent, instinct, and timing is needed in order to produce a beautiful finished product and these guys have a tremendous amount of each one. I highly recommend this team to anyone contemplating concrete work.

Choosing JMK Construction for our deck and driveway replacement needs was a very wise decision. In a time when you hear so many horror stories about various contractors not fulfilling their obligations, we were a little apprehensive. However, John put our minds at ease after our initial consultation; answering ALL our questions and addressing ALL our concerns.

He stayed in contact with us through the time leading up to the job and when it finally came time to do the work, the entire crew were punctual and professional every day and their work was immaculate, as evidenced by these before and after pix. We're so pleased with the end results and cannot recommend them enough to anyone looking to have work done.
