The AquaProof crew was very knowledgeable and efficient. They carefully excavated and installed over 80 feet of drain line around our rear patio, cut through a sidewalk and installed an additional three foot long drain grate, installed the external sump and pump, and also excavated and installed about another 100 feet of drain pipe to tie into the curb at the street. They were very careful to not damage our telephone and TV cables in their excavations, and did a really good job cleaning up all of the excess dirt and debris from the work-site and restoring our lawn with seed/straw. I was very pleased with their attention to detail and care in their work, which was not easy in mid-November. I waited to write this review until after several heavy local rains, where the new drain system had a real workout. Following the recent heavy rains, there was absolutely no water back-up on our patio or around the workshop doors, as the sump pump efficiently pushed the excess water to the street. I have been very pleased that I no longer have to worry about water in my work-shop, at least as long as we have electricity. This company really knows what it is doing and is worth the price.
