Local knowledge that protects your investment

King City homes and lots have their own quirks — grade changes, mature trees, walkouts and older foundations all affect how a deck should be framed and footed. We size footings for our region's frost depth, plan around drainage and existing landscaping, and design to suit the architecture of the home rather than dropping in a generic rectangle. Getting these fundamentals right is what separates a deck that still looks and feels solid in fifteen years from one that heaves, sags or pulls away from the house after a couple of hard winters.

Permits & approvals

Most decks more than 24 inches (600 mm) above grade, or attached to the house, need a building permit and must respect local zoning setbacks. Deck Master Inc. prepares the drawings and manages the permit process for King City projects so everything passes inspection and is fully code-compliant — you never have to chase paperwork with the municipality.
