There are plenty of books out there on building decks. But you probably already have a deck. This aims to fill that gap, dealing with refinishing and repairs. Written by “The Summit Deck Doctor,” whose company has worked on over 450 deks over 10 years, this deals with the process of getting your deck back into shape. It helps you decide between doing nothing and getting it refinished, and doing it yourself and hiring a contractor. All proceeds go to the Loma Prieta Education Fund of Los Gatos (Northern California). Most decks are worth $20,000 and up. Can you afford not to spend $10?
