"Tim was prompt, professional & listened to my questions and answered my questions patiently. His knowledge of materials and costs helped me get this project done well & in my spending plan too. My decks are now in great shape, look better than they have for some time, since Dominion’s very skilled crew replaced worn decking and stained the deck and railings. Our family can really enjoy this special part of our home for years to come now!"

"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. My deck looks brand new. I did not think the deck would come out looking like I just had it installed. I am very happy with the results. Rich gave me a fair price and got the job done in a timely fashion. Thanks Rich. I will surely call on you in the future."

"We had water damage in a room when we were out of town. I hired Joseph and Sons to do the repairs because the pricing was fair. He showed up on time, communicated well and was easy to work with. Angelo worked with me on getting information to my insurance company and found solutions to some ongoing issues we found as the demo started. He also did exterior waterproofing repairs to ensure future water issues would not happen. I had a few extra small requests and he did not nickel and dime us. His workers were very professional and cleaned up at the end of each day. We are very happy with the work and will use on future project."

"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

Yes, deck pier blocks can be used as an alternative to traditional deck footings, particularly for small or low-to-the-ground decks. Unlike poured concrete and buried post footings, deck blocks don’t require digging or pouring. However, their use is regulated by local building codes, and they may not be permitted in areas prone to high winds, earthquakes, or hurricanes. Always consult your local building codes before choosing them for your deck project.

Coping is the material that lines the perimeter of a pool and seals the transition between the top of the pool wall and the water. Decking surrounds the poolscape and extends far beyond the water's edge to provide a safe walking and lounging area. In short, coping is the border between the decking and the pool itself.

The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Yes, you can attach a deck to a mobile home, but it’s important that the work be done correctly to avoid the potential for major damage to your home. Many building codes require that any additions to mobile homes—including decks—be either freestanding or have their own support structures. Getting permits may require submitting the home's original floor plan, the proposed floor plan, framing details, and more. 

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.
