Deck repairs cost around $800 to $3,500. However, your cost depends on the type and severity of the repair, as well as the type of decking material you have. Other factors, like location and labor costs, impact the price, too. Boards and railings are the priciest parts of a deck to repair, while loose stairs are less expensive to fix.

Building codes vary by location, and you should always consult local codes before planning construction. Generally speaking, however, railing requirements stipulate that decks more than 30 inches off the ground need railings for safety purposes. These railings usually need to be at least 36 inches tall, although California and Washington require rails to be 42 inches or taller.

Rotten deck boards can sometimes be repaired, but only if the damage is minor. Repairing small patches of rot involves strengthening the damaged area with wood hardener, filler, or epoxy. More substantial damage requires replacing the boards or rebuilding the entire structure in extreme cases. If the rot extends to the joists, posts, or beams, have a contractor evaluate the damage to ensure it is still structurally sound.

While the chemical, copper-based coating on pressure-treated wood offers protection from rot and pests, it’s not a silver bullet. An added sealant will help protect the wood further, though sometimes the wood is treated in a way that causes premature failure, and this is largely out of your control. It’s simply a case of bad luck. Regularly inspect all your house’s wood to look for any cracks or signs of mold and mildew. Getting ahead of the problem is the key to ensuring it doesn’t grow out of control.
