"Painters arrived exactly on time and accomplished all tasks the same day. The manually stripped the deck and applied two coats of stain. They carefully cleaned and then painted the foundation concrete as it had got dirty over the years. They also scraped, caulked and painted a large bump-out window off our living room.

Deck Cleaning FAQs, answered by experts

The problems with composite decking include a high rate of expansion and contraction from temperature swings. This characteristic can cause boards to split, delaminate, or peel. In addition, significant movement can cause shrinking, warping, twisting, and bending. For this reason, you should minimize moisture and ensure proper airflow below your deck.

Composite decking is the best material for individuals living with disabilities who want to age in place. The material is anti-slip, which increases safety throughout the year. It’s also highly durable and requires minimal maintenance, so it doesn’t add another item to the individual’s to-do list. It’s also a good option for improving wheelchair accessibility at home, as it can easily manage a wheelchair ramp.

What goes under your floating deck depends on your preferences. Some homeowners put landscaping fabric underneath their decks to prevent weeds from popping up through the boards. Others choose to build a floating deck over grass or gravel. However, it’s best not to set your deck directly on the ground. Instead, set your deck on blocks to keep it elevated enough to prevent moisture from rotting the wood.

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.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.
