We had an incredible experience with CGS this year. We had a tree fall on our house at the beginning of the year in a bad storm and CGS came in and worked directly with our insurance company to help us receive the proper amount from insurance to repair the damage. They then did a fantastic and fast job of fixing our house back to its original state. The CGS team is really great to work with, produce high-quality work, and are fast at what they do. We will definitely use CGS for future renovations!

The entire experience with CGS was top notch from the initial inspection and quote to the final finished job. Joel came out to review the job and give me a quote, which was extremely reasonable. He explained the process in detail and assured me that the crew was excellent and would not disappoint. I made several change requests before scheduling the work and they were quickly incorporated into my quote. This was a full dig 10 plus feet deep to expose my foundation exterior with lots of buried plumbing in the front of my house so we were very concerned about the stack stone border wall and flagstone walk and plumbing. The crew was extremely careful and respectful of our property. You will never find a harder working crew they were truly impressive. They were on time and done in 2 days. When they left you would never have known they were there aside from the fact that I no longer had water intruding into my home and the tree I had them remove that was in the way was no longer there. If you want a great job, hard workers, and a price no one will beat then this is your only choice. Thank you CGS.

Jay from CGS did our initial visit and Pierre followed up after a week to complete the job. They repaired my foundation wall in my basement and installed a system to prevent this issue in the future. They did excellent quality work and a great price.
