Deck Cleaning questions, answered by experts

Building a deck isn't too hard if you’re handy with carpentry, have the necessary tools, and are willing to put effort into it. However, other factors, such as plans, permits, and design, can be hard if you don’t have experience in those areas.

Note: You’ll need another person to help you build the deck (especially for framing and setting the beams). Building a deck yourself will be very difficult if you don’t have an extra set of hands to help.

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

There are several methods for attaching stair stringers to a deck. The best way is to bolt the stringers to the deck joists using three carriage bolts in a triangular pattern. This method offers the sturdiest fit for stairs that won’t budge. Alternatively, attach the stringers to the deck rims using lag bolts or to the posts using adjustable slope hangers.

Pressure-treated decking may be worth it if you want a natural, insect- and rot-resistant decking material that will last for decades with proper maintenance. As such, it’s a much better option than untreated pine. Alternative wood decking materials like cedar and redwood tend to be less durable and more expensive. Some homeowners prefer composite decking, which is a low-maintenance alternative to wood but is also more costly.

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.
