FAQ
How do you know when to repair a deck versus replacing it entirely?
You can safely repair a deck when damage remains confined to surface planks, loose balusters, or isolated framing hardware while the primary structural ledger, joists, and posts remain sound. If more than 30 to 40 percent of the substructure exhibits deep wood rot, or if structural footings have failed beyond simple releveling, full replacement proves more cost-effective and structurally dependable.
Can you repair a loose ledger board yourself?
You can tighten existing lag screws or install additional code-approved structural fasteners yourself if the underlying house rim joist and deck ledger remain structurally sound. However, if the ledger board has detached significantly, if flashing is missing, or if severe rot penetrates the home framing, hire a licensed general contractor to ensure building code compliance and structural safety.
How often should you perform a comprehensive deck safety inspection?
Conduct a thorough hands-on safety inspection at least once every year, ideally during early spring before heavy seasonal use. You should also inspect your deck immediately following severe winter storms, heavy snowfall events, or seismic activity that could shift support posts and loosen critical structural connections.
What is the most common cause of catastrophic deck collapse?
The vast majority of catastrophic deck failures occur when the ledger board pulls away from the primary residence due to improper nail fastening, missing flashing, or water-induced wood rot. Railing failures represent the second most common structural accident, occurring when dynamic weight forces push unreinforced guardrails outward.
