Frequently asked questions
Is composite decking worth the extra cost?
Over a ten to fifteen year horizon, usually yes. Composite costs roughly 40 to 80 percent more up front than pressure treated wood but requires no sanding, staining or sealing. In coastal Orange County, where sun and salt air accelerate wood weathering, that maintenance difference is significant.
Do I need a permit for a deck?
In most Orange County cities, yes, if the deck surface is more than 30 inches above grade, or if it attaches to the house. Detached ground level platforms below that height are frequently exempt. Your city building department gives the definitive answer.
What causes decks to fail?
Improper ledger attachment is the leading cause. The ledger is the board fastening the deck to the house, and if it is nailed rather than through-bolted, or if flashing is missing, water gets behind it and rots the rim joist. This is not the place to economize.
How long does a deck take to build?
A straightforward 300 square foot deck typically takes one to two weeks of construction once materials arrive. Permitting adds two to six weeks before that. Elevated or multi level decks with complex railing take longer, as do designs needing engineered footings.
