Get matched with top deck cleaning pros in Hanover Park, IL

When building a deck, #2 grade lumber is a go-to for several reasons. It’s strong, budget-friendly, and works well for most framing and decking needs. But upgrading to #1 or Appearance Grade can give your deck that extra visual edge if you're after a cleaner, more polished look for high-visibility spots.

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.

Footings for ground-level decks need to be at least 12 inches deep, and some areas require them to be even deeper. A standard range for deck footings is anywhere from 12 to 48 inches. The minimum footing depth is determined by an area’s frost line and soil conditions. If you’re unsure how deep to install deck footings, check local building codes to find the minimum footing depth in your area. 

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.
