I had a persistent basement leak and an even greater leak if we got alot of rain . I had a couple companies look at it and could find no suitable solution. I was given David's name from an old friend I had spoken to so at that point I figured what is there to lose? It turns out it was one of the best decisions I ever made to call. David came by and performed his testing and diagnosis while clearly explaining to me the problem at the same time. David did some crack injections ( new to me) from the inside and that was it for the water. I haven't gotten any water since David left and I also have a lifetime warranty ! Thank you David you literally saved my families home ! I wish I could give 6 stars to David !
