Service matters, GSI Foundations assisted me with an urgent matter that helped keep a deal together. Their professional staff worked to have an evaluation performed and provided an honest assessment that made all the difference. Awesome company, I highly recommend!

Absolutely wonderful company to work with! This is an industry that has many bad players, this is not one of them. They were Honest, Accommodating, Fair and Professional. I do home improvements and property management as a side job and would 100% recommend GSI. When my tenant had a water issue and needed this work done ASAP, GSI did everything to get the job done and without predatory change order fees. THANK YOU!!

Thank you GSI for solving my basement water problems. The staff made the process as easy and stress free as possible. Tony, the Project Manager, did a great job keeping me up to date on the process. Tony even took time to call and see if my basement was dry after a heavy rainfall. Good work GSI.

As a realtor, it is important to me that I am able to refer quality contractors for my clients, and that is exactly what I found in GSI Foundations. Not only were they far and above the best quote, but they were also incredibly thorough, responsive, and helpful. I cannot say enough good things about this company--I had to reach out several times to May and Tony and was always met with patience and they were happy to explain things and provide my clients with everything they needed. From the initial quote to the final inspection, I felt as though we were a priority. My client was blown away by the quality of the work and I will certainly be adding them to my referral list! Thank you, GSI!

GSI did a fantastic job installing a drain tile system in my basement. They were more affordable than other foundation companies, and completed the job timely. The drain tile work provided me with the peace of mind to move forward on a total basement remodel. A+

GSI was very professional and personal from the time we contacted them until they finished the job. We had new drain tiles installed on three walls, with one wall needing reinforcement due to deflection. Brian was very knowledgeable and informative in explaining the problem and necessary corrections. During the project, the entire crew was timely, efficient, careful, and neat. They provided covering for our belongings that weren’t already covered, and cleaned up after completion. We were in constant contact with Tony, the project manager, who made sure all tasks were completed to our expectations. Strongly recommend GSI.

They installed new drain tile and a sump pump in my basement about 4 years ago. Since then it has worked well and kept my basement dry! I would recommend GSI to anyone looking to have new drain tile installed.

Matt came out to my house to look at an issue I was having with a basement wall. He was professional and knowledgeable and not once did he try to sell me something that wasn't required.I will recommend GSI to everyone and will definetely call them on my next project.

Amazing experience! Brian and Tony were incredible all around- including their crew. They explained everything upfront and as they went with the project so there were no surprises. They showed up on time and went out of their way to help us. We renovate houses so we will absolutely be using them again!

Can’t say enough good things about GSI foundations. Originally put down a down payment with a different company, my daughter thought I should just get one more estimate. Am I glad I did! The owner himself came out and spent almost an hour checking and measuring everything completely. Found out the first foundation company I was going to hire had missed a lot of things, which would have caused us problems down the road. Tony, Freddy and the rest of the crew were dependable and professional. They showed up when they said they would and did an excellent job at a fair price. In today’s market that’s hard to find. If I could I would give them six stars!! Have foundation issues? Only need to make one phone call to GSI foundations, I highly recommend them!

Very appreciative of Dave and his team. From the initial contact, site evaluation all the way through the process, everyone was professional, prompt and easy to work with. I would highly recommend GSI for any of your basement or foundation issues.

From the initial inspection to the execution and completion, GSI was fantastic to work with! They excavated 35’ of our foundation to push it back where it needed to be. It was nearly 3” out from plumb! They installed all new drain tiles and 49 beams as well. It was a fairly big project and they handled it very well! We highly recommend them for all your foundation needs!

Dave’s crew installed drain tile and sump pump in August on our home. His crew showed up on time and were all very respectful. The work was completed timely and was cleaned up each day. Tony ensured work was completed correctly and answered any questions along the way. Overall I am very impressed with my experience working with GSI and would highly recommend them to anyone needing foundation work. Thanks Dave, Tony, and Crew!

The staff at GSI were very personal and helped me with my basement problems..It was a 2 family, the staff kept me informed of the time line so I could inform the tenants and they cleaned up everything . The basement issues went smoothly. I used them yrs ago with great success and I would use them again. Good job.

Dave at GSI Foundations is incredibly knowledgeable and an expert in his field. He was easy to work with and excellent at explaining the work that needed to be done for our basement project. The work was efficiently and effectively completed, and within weeks of completion, held up perfectly to significant "once a decade" rainfall without issue. I am incredibly pleased with both his management of the project and the finished product. Highly recommend!!

Water came rushing into our basement from the floor! Brian from GSI called us back over the weekend, came out immediately and identified the issue within minutes. He fixed it the same day! Before Brian, we had 6000 gallons of water in the basement. By the time he left the flooding had stopped and the water was completely drained. I cannot say enough good things about Brian and GSI. They are amazing!!!

We called for help when we had water in our basement. Brian responded to our call the sameday. Discussed our problem and scheduled to come out within days not weeks. When Brian arrived he spoke to us in language we understood and was clear about the fix we would need. After that short meeting with him we could tell he would be someone we could work with.

The GSI experience was terrific. Work was done both professionally and efficiently. Great care was taken to preserve the existing landscaping in the work areas. Clean up of the job site and the end results were excellent. Explanation of what needed to be done and communication during the work could not have been better. Nobody wants to deal with foundation issues but GSI made it painless. Highly recommended.

GSI assessed all issues in my basement quickly and accurately. They were prompt and completed the job in a timely and professional manner. Even after they were done with the job. They still stopped by and checked on things and helped me pinpoint a separate unrelated issue I was having. I will be using them again in the future and highly recommend them. Thank you for all of your help!

GSI Foundations was great to work with! Of course with my company name you know how important a good foundation is :) Team was responsive, great value and helped educate me along the process which was really important for me. They were able to complete drain tile and bracing in a timely fashion, took care of permits and made sure the job site was cleaned up.

As a real estate broker, it is a privilege to recommend GSI Foundations/Solutions to clients and customers knowing the work will be done right and at a good value. As a recent customer of GSI myself, I can say the recommendations I have made over the years are 100% backed up by my experience. Top notch, well done work at extremely competitive pricing.

Given the fact that no homeowner ever really wants to hear that they have foundation issues, GSI provided a professional, reliable and quality service in completing the job at my residence. They reinforced all four walls in my home with steel beams and installed interior drain tiles. They always showed up on time and were available to answer all of my questions and concerns. The work performed was done correctly and to the highest level. I would recommend to anyone needing foundation/ basement wall work to use GSI.

Excellent, professional experience. As an Architect, I have dealt with many contractors, and GSI hit all the right attributes of a good contractor. He did what he said he would do, at the cost he quoted, in the time table he promised and communicated well. Can't ask for more than that!

I hired these guys to repair a foundation and install drain tile/sump pump on a house. Dave was great to work with. Very responsive, got the job done on time, and did great work. I'm really happy I hired them to do this work!

I'm giving this company another 5 star review because they deserve it! They went above and beyond on my last basement project in Bayview. I renovate homes and GSI Foundations is the only company I will use - professional, they stick to deadlines, and they get the job done correctly. You will not be disappointed!

I first met Dave during his basement presentation at our local REIA meeting. He provided a simple, comprehensive method for assessing basements. Even offered to look at the assessment and provide feedback. I was so impressed that I hired him to install drain tiles at my rehab. His crew and foreman were on the job, working efficiently, meeting contracted work standards and delivering a superior product neatly installed, leaving the area clean and neat. I will be sure to hire Dave again and recommend him to others.Dorothy WilkinsonBlue Fox Homes llc

Dave and his crew wenty above and beyond. Dave’s crew worked tirelesssly to do a new drain tile for a 100+ year old home in waukesha. His prices were much more reasonable than other quotes we got, and we thought the value for the price was well worth it! I would recommend Dave and his crew to anyone!!
