We had successfully used Terra Firma about 10 years ago, so when we had a water incursion this year in a different part of the house we naturally turned to them again. To address water coming through a wall in our daylight basement, they installed their Water Guard and Vapor Lock products, plus a sump pump system. The result looks solid and neat. Haven’t yet had a chance to test it in a downpour, but I’m very confident that if there’s an issue, TF will make it right. I know that because some of our rickety plumbing got dislodged during this process and started to leak. TF stepped up and sent 2 high-quality plumbers, and they found every issue and fixed them all. The install crew themselves were super-courteous and tidy, and they worked overtime to get the job done timely. Kudos to Antonio Rodriguez, Jacob Rodriguez, Rico Aguilar, and Jonathan Heredia.
