Great service at affordable prices
I am an investor and have used GSI multiple times. I am always extremely happy with them. They have really helped my rehab business and I never shy away from rough basements when looking for properties knowing they can handle it. Thanks again guys!
They came highly recommended to me and I was very satisfied. The scope of work was explained very well to me and I felt confident in what they needed to do. I will definitely recommend them to others.
Super job. Wow these guys work hard. Thanks!
"As a real estate broker, it is a privilege to recommend GSI Foundations 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."
"I've known Dave and his crew for a few years and have used them several times as well as have referred them to multiple customers. I wouldn't hesitate to continue doing the same moving forward. The best customer service and quality on the street!"
I had a drain tile system put in my home by GSI. They were very prompt, & very professional! I was quite impressed at the quality of work done, how fast it was completed & the cost was under what I expected for a job this involved. Thanks again GSI!
"Great company, needed the job done quick and Dave and his team were able to accommodate. Job quality was topnotch. Dave went above and beyond to make sure I was satisfied."
GSI was great to work with for our foundation repair. They got things done quickly and did an excellent job!
GSI foundations did a wonderful job on bracing a basement wall for me. They were prompt and provided a free estimate on the work.. The braces are custom made and were installed in a day.
"I have worked with GSI many times and have had nothing but a great experience. GSI has always been a company that will fix what needs to be fixed not just try to sell you more. Great people, Great workmanship at a Great price! I highly recommend them!"
I am so impressed with the quality of work that you guys did in my basement. When I was looking for estimates I didn't fully understand what they wanted to do with my basement until GSI came and took the time with simple words for me to understand what they were going to do. I recommend you using GSI if you have any problems.
"Great price, great service, and their turnaround time was incredible. I will definitely use them again for any future projects."
"Excellent work. Their pricing beat out all the competition. Professional and they cleaned up after themselves. A++++++"
"I cannot say enough good things about this company. Incredible service and quality and they are always the least expensive out of all the quotes we get. They clean up after they are done too. I am so impressed by the way this company operates. Keep up the outstanding work!"
“I've worked with Dave Graf and GSI Foundations on many basement projects and they always come through without a doubt. Being a real estate investor we are always looking for the best people to work with and their timeliness, quality, and pricing are second to none. If you are having any basement issues, whether it's water in your basement, cracks in the walls, sump pump issues, or any other basement problems these are the guys to call. I recommend them to everyone I know.”
"I highly recommend GSI Foundations! Dave, the owner, is accommodating to your schedule, quick, efficient, honest, reliable and his workers do a great job! Totally satisfied."
Dave and his crew went above and beyond. Dave’s crew worked tirelessly 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!!
Dave is my go-to basement contractor every time! You won't find better work or a better price! Highly recommended!
"Very professional, great communication, well done work."
"GSI did an awesome job , cleaned up after themselves great job at a great price . I am very pleased with their work and I would recommend them very highly."
"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!"
"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 Foundations was recommended to us. Called them to come and check out the basement and they came the next day. Within a week, the work was done! The workers were very friendly and always cleaned up afterwards. Highly recommend GSI Foundations"
"GSI did a great job fixing our basement. The team was on time everyday, they were fast, clean and most importantly the bill matched the quote and they fixed the underlying problems."
I called David with what I thought were foundation issues. He was extremely helpful and gave me some excellent advice with regard to my water issues. During both of my calls he was very informative and patient with my questions. Based on how he handled my situation, he would be the first one I would call if I needed work to be done. Thanks David.
"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 Wilkinson Blue Fox Homes llc"
"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!"
"We are local realtors and refer all our clients to GSI. Very professional and all our clients are very pleased . Thank you!"
"We needed our job handled quickly to allow for our closing to happen on a certain date, they not only came in took care of us and got it done on time they also did it at an affordable price! I also referred them to a friend and the friend sent me a thank you card, she said they had a great experience as well"
"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."
"Dave and his team are a pleasure to work with. Great communication, they make the repairs easy to understand and make the jobs run smoothly even if tenants are involved. Always my number one recommendation for basement and foundation work."
"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!"
