We first had an estimate from TC Hafford about 5 years ago, but didn’t do anything until this month. We shouldn’t have waited! They have done an excellent job in our basement and crawl space. Our house was built in 1892 and sits on ledge with a hand dug “cellar” that was always wet. Whenever it rained the water flowed over the ledge and into the cellar portion. TC Hafford has completely sealed the crawl space, drilled and installed a sump pump, and poured a new cement floor. What a difference! The whole basement is clean, bright, and most importantly, completely dry. We can’t say enough about the service we received or the results!
