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.

It depends on the type of wood. The average cost to build a deck out of pressure-treated lumber is $15 to $25 per square foot, but more affordable varieties such as bamboo and cedar cost less at around $3 to $10 per square foot. However, when comparing the cost of vinyl decking versus wood decking, it’s important to also consider ongoing maintenance costs. For example, most woods require regular sealing to keep them protected against weather and rot.

The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.

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.
