My deck had been rotting from the bottom and I didn't know what to do. It wasn't safe for my kids and dog to play on a deck with so much rotting wood. I would often get slivers just walking to the bbq. I hered the Deck Doctors to come and replace a few sections and to restain the deck, with waterproofing. The deck looks amazing now and I feel as though it's life has now been prolonged. I would reccomend these guys to anyone with deck issues.
