"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!"

"Experienced Landscape Design did a fantastic job for us trimming 3 large overgrown hedges, yew, forsythia, and privet, and clearing weeds from planting beds. We anticipated a good outcome from the moment we met owner Paul, because of his evident love for this work, enthusiasm, and energy. He assessed our property, answered questions, and pointed out areas we might want to include in the service either now or later. We received a very fair estimate next day, and the job was completed the day after that. The crew worked for 7 hours with care and thoroughness, shaping the hedges artfully, exceeding my expectations. I was so delighted with the result I think I applauded. This company is a keeper, and we look forward to working with them in the future."

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

Deck Maintenance questions, 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.

While you can use various materials like sand or even just soil, gravel is widely considered the best option to put under a deck. It provides excellent drainage and is resistant to water, fire, and pests. Gravel also helps anchor the soil to prevent erosion during heavy rain and acts as a built-in weed blocker, reducing regular upkeep. Furthermore, it is simple to spread, available in various textures and tones, and adds a polished look that complements any deck design.

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.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems. 

In the majority of cases, you don’t need regulatory permission or permits to remove decking components and materials. However, the exception is if you live in or near a wildlife conservation area, which could require permits and consent prior to beginning the demolition. Check with a local regulatory agency for more information.
