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.

Spoke with someone a day before to receive a quote. My appointment was scheduled from 9-10 am. Received text asking if 10-11 am would be okay. I agreed. At 10:30 am received a call from a guy stating that he was given an address in Atlanta and I live in Gwinnett County. Off work waiting for the technician. Who is a no show. The office calls within minutes to say there was a glitch in their system. No thank you!

My home has been needing help with foundation lifting- this company never reached out nor attempted to get back to me after several messages. Be aware of their lack in communication.
