"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

To maximize the utility of space under a deck, it’s important to keep this area dry and clean. One way to prevent the area from becoming too wet is to install an under-deck draining system. This affordable home upgrade channels water away from the deck and provides usable space for storage or a functional area below a second-story deck. Not only will this be a useful maintenance upgrade, it can boost your home’s property value.

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.

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.

The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.

Ultimately, overapplication of stain can compromise the deck's appearance, durability, and longevity. It may result in an uneven finish, with excess stain pooling, dripping, or drying into thick patches. It can also obscure the wood's natural grain and texture, detracting from the desired aesthetic. Moreover, excessive staining may not fully penetrate the wood, leading to poor adhesion and premature wear. Additionally, thick layers of stain are prone to peeling, cracking, and blistering as they struggle to bond with the surface.
