★ 5★ 4★ 3★ 2★ 1I have been working with GSI for over a decade and will be sticking with Dave, Jodi, Matt, Toni, May and the team for a great while to come! We do 6-8 basements with GSI every year in our home rehabbing business and we really feel like its about the easiest contractor decision on every project. The work quality is awesome and reliable - they tailor each project to exactly what we need and pricing is always very fair. Everyone communicates very well and the work is always completed lightning fast so we can carry on with the rest of the project. Highly recommend GSI Foundations!
May 13, 2025 · Craig KonkleI’m a realtor and have used GSI multiple times for clients over the years. Every experience has been positive with my clients thanking me for the referral. I’d recommend them to anyone needing foundation work. Reliable, honest, and competitively priced!
Aug 01, 2025 · blake retzerGSI solutions/ Foundations did a drain tile installed in 2016. Over the years had flooding in my basement that I couldn't figure out why. Finally called a Foundation company was informed that there was some work done to my basement and to check with the city to see if any permits where pulled. Called the city. Got copies of the permits. Found out GSI solutions at that time did was the name of the company installed 109 liner footage of drainage tile, support beams and patched out some walls. Reach out to GSI solutions/ Foundation. Had Tony from GSI come out. Was informed that there is nothing wrong with my drainage tile. It's my downspouts and grading. Did some deeper research by getting a plummer to video my drainage tile. Come to find out8 ft from the crock pot where the sum pump is the perforated tile turned into cray tile on one side of the house and the other side had some built up debree and clay. Reach out to GSI solutions/ Foundation regarding this matter. Tony from GSI Solutions/Foundation stated he would reach out to his manager. Have not heard back in weeks. Hired an attorney. Was advised to do a drainage tile test and was informed that GSI would reimburse the cost. The drainage tile from Bob independent drain tile test company did the test. Stated there is nothing wrong with my drainage tile which I disagree because the plumber that camera the tile stated otherwise. Then I was informed that they wanted to do another drainage tile test through Reeds Drainage tile company because it wasn't sufficient enough evidence which was to cut drywall down and flooring every few feet. Was told that I as a home owner would be held liable to fix the drywall and the flooring and any preparation that would cause this test to get performed. I didnt see the need to do another drainage tile test one was already done and the camera showed that the drainage tile was installed incorrectly. Them I was told that the water that I have in my basement is because of the cracked foundation. Based on my research and having other basement Foundation company's assess the issue. If you have water coming from the top and you don't have the drainage tile installed correctly it will cause Foundation walls to crack because of the moisture that causes the walls to expand and crack. The attorney that I hired to help me with this issue he is a piece of work himself. He wanted me to tear down the basement walls and flooring and make me liable for something that GSI foundations/solutions installed incorrectly. The isn't enough weep holes where the drainage tile is installed, nor there is not enough perforated tile installed Based on the permits pulled because it turns into clay tile that was originally installed when the house was built, the support beams show rust on the sides. Which rust comes from moisture. I see that there is alot of good reviews by this company. I wish I could say the same, unfortunately this has been a nightmare for me and one expense that I didn't expect to have. A good structure of a house is so important to have with proper drainage tile installed otherwise it cause many problems to a home owners. Im very disappointed matter. I dont wish this upon any home owner.
Jan 23, 2025 · Monika ChudzikFantastic company. Best price I could find, and the best workers I may have ever seen. The GSI team reinforced my entire basement over a 2 day period.... during a snow blizzard. I do not know if the team even took a break. I would highly recommend GSI for any basement/foundation needs. The end product has held up perfectly and they kept me in the loop step by step the entire process. 5 stars for sure!!
Jan 27, 2025 · michael williamsHad a great experience with GSI. They were very prompt in responding to my call and arrived on time. The team was thorough, inspecting both the inside and outside, and provided a clear, fair estimate. Their professionalism and attention to detail were impressive. I highly recommend GSI
