"Robert and his crew were great! They were very thorough and professional in completing my deck repair. They offered insight while completing the job to enhance the final appearance. Robert extended his time and completed tasks not included in the original contract without additional compensation. Everyone was very personal, polite and cooperative. I would very highly recommend New - Gen Construction for any deck related projects."

"Mandi and his assistant did a great job on our deck. He replaced the flooring, support post, and other elements that needed repair. He then sealed and stained, two coats each. All work was completed in 3 days! Mandi's professionalism and expert craftsmanship were evident in the final product. We especially appreciated how Mandi discussed details and consulted us about our preferences when changes to the original plan were needed. I highly recommend hiring Mandi."

"Excellent job. The team was meticulous in preparing the deck prior to stain application. They took extra care in removing years worth of debris between planks (and painted over). Also, an excellent job in power washing the house and front walkway. They were courteous and professional."

"Ivan and his team from Top Quality Home Renovation did excellent work on my home. His team did multiple projects for me. They replaced my asphalt shingle roof, repairs my cracked chimney, updated and painted my deck and wood shed. They painted my cement walkways and reset my paver stones. His prices are very reasonable and his work ethic is phenomenal. They pay very close attention to details and always aim to please the client. I will definitely recommend them for any roofing or deck projects."

Deck Repair FAQs, answered by experts

A deck that isn’t attached to a house is called a floating or freestanding deck. These standalone decks are built near ground level, so they usually don’t need deck stairs. Some don’t even require permits. Generally speaking, building a floating deck is faster and more DIY-friendly than constructing one that’s connected to your home.

You can build an outdoor kitchen on a deck, but you should choose composite decking since it's more heat-resistant. Metal deck materials like steel and aluminum are also good choices because they're less flammable than wood. You should also consider the weight of the kitchen—make sure your deck can support it and any appliances you plan to use. You should consult a structural engineer to confirm exactly how much weight your deck can safely support when building an outdoor kitchen. 

Your deck may look or feel fuzzy after pressure washing because the high-pressure spray tears some wood fibers as it removes the outer layer of dead and discolored wood. This fuzzy effect is a normal part of the pressure-washing process and will go away on its own in a few weeks. You can opt to spot-sand your deck if you’d like to remove it more quickly.

Choices include wood, composite, and hardwoods, each with unique benefits.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.
