"We had Stratum come out and give us a bid on some hydrostatic water issues we were having in our basement. From the initial bid to the finished job, we were very impressed with the team. They worked with us in terms of communication, scheduling the job to completing the job and cleanup . They put a water diversion system in place and I’m happy to say the recent heavy rains proved that the issue was fixed." says Sharon on Google

"I can't recommend Stratum Structural Systems highly enough. When I called them out to look at a large void under my front porch and a sunken sidewalk, they easily could have sold me on a costly repair. Instead, they took the time to walk me through the underlying issues in detail, recommended a different approach, and turned down the job altogether. It's rare to find a contractor with this kind of integrity." says Barbara on BBB
