"Rich, owner of RAP, and his dedicated crew did an awesome job in power washing our house, storage shed, deck, and brick walkways … everything is clean, bright, and frankly looking like new again! Rich is knowledgeable, responsive, punctual, professional, and an absolute pleasure to work with. He and his crew were meticulous in their work taking their time to do a job that well exceeded expectations and were conscientious in their clean-up efforts afterwards. It is indeed rare these days to see extraordinary focus on customer delight and pride in their work. I highly recommend Rich and look forward to working with him again in the future!"

"John and Lou were very professional and did a great job on power washing, sanding, and staining my large deck. They went out of their way to make sure everything worked out. The deck looks amazing now, it's the best I've seen it look in many years. John had great recommendations to make based on his expertise such as the stain type and color to use as well using great methods to ensure the final product came out excellent. Would hire again and recommend their services to anyone."

"Sandro and his team did excellent work, professional and great customer service. He wanted us to be more than satisfied with the work. I was very happy with the results. I thought my deck was beyond repair with the dirt and mold but with a thorough cleaning, light resurfacing and stain of my choice it is as good new."

Deck Maintenance FAQs, answered by experts

You typically don’t need a railing and handrails on a deck that’s less than 30 inches from the ground. However, consider adding them regardless. Railings provide additional safety for you and your guests who use your deck—plus, railings give the deck a more finished look than it would have without them.

Because adding a deck will yield a higher property value, you may have higher insurance costs. It’s important to follow the codes and regulations set by your local and state governments, so your insurance rates can be properly calculated. You may need an insurance revaluation after your deck is completed. The best course of action is to speak with an insurance professional to understand how adding a deck will impact your home’s insurance costs before you begin.

In most cases, your deck will need some form of deck footing to hold it in place, preventing moisture from rotting your wood and decreasing your deck’s lifespan. Concrete deck blocks are the most common type of footing for floating decks. Some homeowners use ground-level deck footings. For added security, consider digging and laying your ground-level footings below ground.

It is recommended to clean your deck once or twice a year to prevent the accumulation of dirt, debris, mold, and mildew. The ideal times for cleaning are in the spring and fall. A spring cleaning removes grime that has built up over the winter, preparing your deck for summer use. A fall cleaning washes away messes from summer activities, preventing them from setting into the wood over the winter. The exact frequency can depend on factors such as how often the deck is used, its exposure to pollen, and whether salt was used on it during the winter. Regular cleaning helps protect the wood and its finish from damage.

Composite decking requires a solid foundation or substructure for support. This base is typically a frame composed of posts, beams, joists, and footings. The frame can be built from various materials, such as composite, plastic, timber, or metal, depending on your budget, deck type, and environmental conditions. For maximum stability, a professional deck builder may recommend installing this frame on top of a solid concrete base. It is best to discuss the most suitable substructure design and materials for your specific project with a professional.
