"Everything went great. We were told about N&Z by a friend. And omgggg. Thank you with all the rain we have had our roof literally was garbage. They tore off all our old roofing cleaned up Everything from that mess. And put a whole new roof on our 2200sq roof. They did it fast and let me just say their prices cannot be beat. I also hired them to do a weekly cleaning in my house. Which so far has been the best and biggest help. Highly recommended"

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.

That depends on the condition of your deck. An older deck that looks drab, worn, or has multiple damaged boards might be worth replacing before selling. However, if your deck is in good condition, you can simply clean, repaint, or stain it.

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

It is possible to pressure wash your deck, but it’s usually best to leave the work to a professional for two main reasons. First, power washers are expensive, and you can avoid high upfront costs by hiring a deck washing pro instead. Second, you must be careful to use the correct setting to avoid damaging your deck material. You can only clean soft woods like pine with a wide spray and a low pressure; otherwise, the water will leave unpleasant marks on your deck. Hard woods, composite material, and metal can stand up to increasingly higher water pressures.

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.
