Client Reviews

Landslide Repair for Homeowner in Colorado

I would like this to be a letter of appreciation and gratitude on a job well done. Our house was first threatened by a landslide back in June, 2017 and it has been a journey that has been both stressful and scary. And yet, every cloud has a silver lining and in this case the support, encouragement and character of everyone we met from GSI has indeed been a gift throughout this journey.

GSI was recommended by Steve Pawlak and we met Nathan Thompson early on. Nathan is a person who inspires trust and our first impression was verified throughout the process that led to a retaining system that has saved our house. As with everyone, and I mean everyone we met, we felt we had a group of people who were on our side.

There were challenges that were overcome; the patience needed along with several visits to get the project underway, a renegotiated plan and bid when the insurance settlement squeezed the payment amount, and a time crunch that led to a change in plans where the panels were poured on the hillside, that allowed for the project to be started as quickly as possible.

The crew that showed up to do the work was respectful, always ready to explain what was happening and was also timely, hard working and ready to go the extra mile. A great group of people with positive attitudes who seemed to genuinely work well together.

Watching Spike work on that excavator was awe inspiring. One of my favorite moments was filming him on my phone to show my office secretaries at the Elementary School. I recorded a "holy shit" without knowing it when he pulled off an amazing stunt coming off a ledge and then being horrified when that came out while I was sharing the video at school. I was able to laugh later.

Thank you again and if I can ever serve as a reference, please let me know.

Transformative Project for Homeowner in Minnesota

Just wanted to say that somehow your workers/artists took an ugly and scarred piece of this earth and turned it into a very pleasing and contoured piece of this earth. It looks incredible!! The fellows were all so nice and just wonderful to us. They worked so hard and were always hear early…….no goofing off…. just working. My husband suffered a traumatic brain injury in early 2012 and it has been a rough couple of years. He is almost completely healed. There were many tears and a lot of frustration. Seeing this project and the amazing workmanship put into it has really put a smile on our face. We thank your fathers for getting this company up and running. We thank you and Tim for keeping it running. Your company made a difference in our life and one we will not soon forget. It is easy to say thanks…it is hard to put into words.... but know that our thank you comes from the heart!!!

Foundation Grouting and Structural Repair for Homeowner

I wanted to drop you a quick note. Late last year I had Tom Szynakiewicz come by and advise me as to what I needed to do to fix my house structure. Tom and GSI were great to work with to find a solution for my structure issues. GSI did an excellent job for us and got us on the right track with the work that was performed. We just sold the home last week, and disclosed the work that was done. We had zero issues with selling the home because it was fixed by GSI. I am very thankful I called and got you guys involved! Thanks again for steering me in the right direction Wayne!
