"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.

Yes, and in some cases, frozen ground may improve the digging process for footings due to sturdier conditions. It’s easier than working in muddy conditions, which are more common in the spring. Contractors may use machinery that makes this step a breeze, so harder ground shouldn’t affect the building process.

A cedar deck can increase your home's value if the project is executed well. The value added by a deck is influenced by factors such as location, materials, and craftsmanship. In regions with warmer climates, decks are particularly desirable, enhancing outdoor living spaces.

The key to getting the most value out of your investment, both in terms of home value and personal enjoyment, is to make sure your deck is built to exacting standards. You should consult with a professional deck builder to get the best results and the highest ROI.

Local building codes don’t specify the number of steps a deck can have before a railing is required, mainly because stair height varies widely. Most areas require decks 30 inches or higher to have a railing. While not exact, that roughly equates to four to seven steps.

Unless you’re using a 2-in-1 formula or painting over an existing coat of paint, it pays to apply a coat of primer ahead of your new paint. Decks see a lot of footfall and exposure to extreme and sudden temperature changes and moisture levels. The primer promotes better paint adhesion, moisture repellency, and a smoother finish, which means you’ll often need fewer coats of paint.
