Deck Repair in Mercer Island

Why Mercer Island Homeowners Choose Deck Repair

We repair decks across King County — board replacement, ledger reinforcement, post base repair, and structural rebuilds. Our repair process starts with a structural assessment: if the frame passes, resurfacing makes financial sense. If it doesn't, we tell you before you spend money on surface repairs that won't hold.

Pacific Northwest deck failures follow a pattern: surface boards look rough, but the real problem is the ledger connection and post bases. Forty-inch annual rainfall plus freeze-thaw cycling degrades wood at connection points faster than at the surface. A deck that looks like it needs new boards often has hidden structural decay that makes resurfacing a false economy. We check the frame first, every time.
