Deck Cleaning FAQs, answered by experts

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.

Always sand a deck before repainting so the wood is smooth and ready for paint. While you do not need to fully remove paint before repainting, sanding helps remove any areas with weather and sun damage. Sanding also helps remove chipped or flaking paint and opens the wood pores to improve paint adhesion.

The cost to build a second-story deck averages $4,800, though the actual price could range as low as $420 to upwards of $16,000. While labor costs range between 35% and 50% of the total project cost, the materials and complexity of design will ultimately lead you to save or spend more money on this home addition.

A quality, well-maintained PVC decking can last 30 to 50 years. It’s known for being one of the most durable types of decking materials, with composite decking having a 25- to 30-year average lifespan and some softwood deckings only lasting 10 to 15 years. Luxury hardwood decks like Ipe may last longer than PVC decking, but they can cost more and require more maintenance.

PVC decking tends to be cooler than composite because the material is less dense and absorbs less heat. However, it depends on the deck’s color. A dark-colored PVC deck may run hotter than a light-colored composite deck. If you’re concerned about your deck getting too hot, it’s best to stick to a light color such as beige or gray.
