"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!"

"Paul and Laura were fantastic to work with. They really listened to what we wanted to accomplish with our project and which plants we wanted to save in our old beds. They went with me to the nursery to discuss what kinds of plants I liked and create the style I was looking for, using their knowledge of what would grow well in my area and be deer resistant. They were very willing to work within our budget and then went above and beyond to give us the best experience. We were so happy with the garden renovation that we have now hired them to do all of our weekly mowing, weeding and maintenance."

"I would recommend this company to others. They are professionals that go above and beyond expectations. There are few roofing companies willing to come out to clean gutters on an old house. Their workman was quick and efficient while being respectful and friendly. I am so glad to find a company with great customer service"

Deck Maintenance FAQs, answered by experts

Yes, it is possible to add an under-deck drainage system to an existing deck by retrofitting it to the structure. This process may require some prep work. For example, many drainage systems are installed on top of the deck joists, which would require you to remove the decking boards and railings first. To avoid this, you could opt for a below-the-joist drainage system. For best results and to ensure proper installation, it is recommended to consult a professional. A pro can inspect your deck, make any necessary repairs, and then install the drainage system correctly.

It is definitely worth sanding a deck to ensure the wood absorbs new stain. Sanding a deck removes the outer layers of aging wood, allowing the stain to penetrate. It also gives a fresh look to the entire surface as part of the deck refinishing process. Without sanding, your stain or sealant is less likely to absorb into the wood. While sanding a deck is a time-intensive project, the rewards are noticeable and long-lasting.

Hangers are one way of attaching stair stringers to a deck. These metal hangers are usually adjustable, allowing you to find the ideal angle for a secure installation. They’re the best choice for installing longer staircases, such as one on a two-story deck, to reduce the load on the deck frame while keeping the stairs stable.

When deciding if you should use 2x6 or 2x8 deck joists, consider the size of the deck, joist spacing, and materials. Larger decks, larger-spaced joists, and weaker wood all require more support, meaning they need larger joists. For example, 2x8 redwood joists spaced 16 inches apart can only safely span up to 10 feet and 7 inches. On the other hand, 2x10 southern pine joists spaced 12 inches apart can be as big as 16 feet and 2 inches. If you aren’t sure what size joist is best for your project, speak with your deck builder.

Yes, you can build a deck around a fire pit, as long as it is safely enclosed, meets code requirements, and is at least 15 feet away from your home. You’ll want to ensure you have a heat-resistant barrier between the fire pit and your deck to prevent any structural damage and fires. A galvanized ring surrounded by pavers, brick, or stone makes for a beautiful, safe, and sturdy design.
