    Posted by Richard E.on 06/30/2022

    Stratum repaired a crack in our basement wall that water was leaking through. It was a crack that had been repaired by another company with a â lifetime warrantyâ . However, the â lifetime warrantyâ was not honored due to a reason that the company stated. So, I used Stratum who repaired the crack correctly and it has not leaked since. The Stratum personnel were very professional in their work, doing it the right way and cleaning up throughly after the job was complete.
