We were referred to the Basement Guys by friends who had water problems successfully repaired. We hired them to repair a wall crack which was complicated by a finished wall in the basement and interlocking outside. The Basement Guys repaired the crack from the outside. They returned the patio to better than it's original state. They also took a number of photos of the repair. We have had many heavy rainfalls with no issues. Completely satisfied and highly recommend them.
