I've had negative experiences with other foundation companies, warranty calls, cracks that still leak, etc. Craig explained their process, walked me through options, and I ultimately decided on a crack repiar + waterproofing system with sump.

Brandon came out first and did the crack repairs. A big.." says Scott on Google

"Matt Wittman came out to inspect an existing egree window. Matt gave us several contacts to get the window addressed with conservative treatment rather than jumping straight into new window installation. It’s extremely rare to have a company recommend cheaper options rather than wasting homeowners money on services they don’t need. I would recommend Matt and his company to anyone. We will definitely be using them in the.." says Jon on Google

We contacted Stratum and received a quick response and met with Keven Welch for an estimate. Very knowledgeable and responsive to all our concerns and needs. He promptly sent us an estimate that was much less.." says Jean on Google
