Deck Maintenance FAQs, answered by experts

Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won’t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn’t look as natural. Keep in mind that you’ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

No, you don’t need a permit to repair and replace a few boards on an existing deck. However, if you’re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor who builds decks for advice.

Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it’ll cost you much more if you’re caught.

Wood decks need to be replaced every 10 to 15 years on average. Natural wood is highly vulnerable to infiltration and damage from moisture, which can occur rapidly due to exposure to outdoor elements. You can protect your deck and maximize its lifespan by sealing it every year or two.
