"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

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.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.

A random orbital sander is best for sanding a deck because it is easier to handle than other power sanders and is less likely to damage the wood. Most decks are made of types of softwood, so a gentler sanding process is essential to prevent permanent blemishes. For example, belt sanders can gouge softwoods.

It's okay to walk on a newly painted deck after about four to six hours as long as the weather has been dry. Be sure to wait at least 24 hours before you place any outdoor furniture or grills on a freshly painted deck, though.
