Erica and her team found the actual source of my basement leak after two other companies gave up. Fixed it in one day and backed it with a lifetime warranty. Couldn't be happier.

Professional, honest, and fairly priced. They installed a new sump pump with battery backup before the spring storms hit. Slept well through every rainstorm this year.

Got three quotes for crack repair. Seepage Seal wasn't the cheapest but explained everything clearly and gave a lifetime warranty the others didn't. Worth every penny.
