Deck Maintenance questions, answered by experts

Composite decking might cost more upfront, but it delivers value in terms of durability. Unlike wood, composite material resists common deck problems such as rotting, fading, warping, and all the other things you don’t want a deck to do. The extra processes lead to a higher price tag, but you’ll save big in maintenance costs down the road.

Before installing any materials under the deck for removing moisture, you should perform some prep work on the ground. Work the dirt under the deck to create a grade away from the home. A grade of at least six inches for every 10 feet works well. Do not leave a gap between the dirt and the home’s foundation where water could pool. Once you or a contractor regrades the dirt under the deck, you then can add materials over the top.

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

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.

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.
