"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."

The craftsmanship is outstanding—the railing looks amazing and feels extremely solid and well-built. You can tell they take pride in their work. I highly recommend Prescion Home Repair to anyone looking for reliable, high-quality home improvement work!"

Deck Maintenance questions, answered by experts

The proper and most comfortable height for a deck stair riser, also called a step, is between four and seven inches. A height of seven inches is often considered ideal for a strain-free step that minimizes the risk of trips and falls. While it is possible to have risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. For optimal safety and comfort, pair a seven-inch riser with a tread depth (or run) of at least 10 to 12 inches. Always check your local building codes, as they may have specific requirements that differ from these general recommendations.

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.

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. 

The best time to paint your deck is when temperatures are neither too cold (below 60 degrees) nor too hot (above 85 degrees). Always paint your deck when there’s no risk of rain. For fast-drying paint like acrylic or latex, ensure your deck can dry for at least four hours. Oil-based paints take longer to dry and may require 48 hours to completely cure.

It is possible to pressure wash your deck, but it’s usually best to leave the work to a professional for two main reasons. First, power washers are expensive, and you can avoid high upfront costs by hiring a deck washing pro instead. Second, you must be careful to use the correct setting to avoid damaging your deck material. You can only clean soft woods like pine with a wide spray and a low pressure; otherwise, the water will leave unpleasant marks on your deck. Hard woods, composite material, and metal can stand up to increasingly higher water pressures.
