My experience with Matvey was 5 star from start to finish. They are very professional with the estimate process. I chose them over cement slur injection. From start to finish, they were on time and did a very professional job. The office support was outstanding. The Poly-Fill injection system was almost invisible. My exposed rock concrete front porch and side walk repair is perfect. I'll use them again if needed.

It was a small, but difficult job, handled professionally. The crew was on time,no nonsense, and cleaned up before leaving.. Significantly more reasonable than the other bid I got.

I was very pleased with their level of professionalism and competence. They were prompt for both the estimate and work appointments. They left the work area as clean as they found it. All at half the cost of the next bid!

I had Lots of major cracks on two large slabs and parts were sinking, they came out a did a wonderful job leveling both, I saved alot of money by filling the cracks myself, a near impossible job done well. I will use them again this summer to fix my front retaining walls, Matvey is a very customer oriented and easy to work with. and thier prices are better than most other services out there.

Price looked good so I hired them. The "crew" showed up an hour late having no idea what they were supposed to do. I showed them around and explained the footing drain they were supposed to install. 2 hrs later they called and said they were done for the day and would finish up tomorrow. They had dug an 8" trench (quoted 24-36") not even close to what a footing drain needs to be. Clearly they had no idea what they were doing, luckily I knew better. 1 full star since they refunded my money...

I was extremely satisfied with the work that Matvey Construction did to stabilize a portion of the foundation of my home. The workers were courteous, efficient, and extremely hardworking getting the job and clean up done in less time than I had expected. I feel confident that my foundation is now secure and would highly recommend the company and its product to anyone needing similar repairs.
