"Recently we had Supreme Painting and Maintenance come to paint our two decks. Their work from the beginning to the end was nothing less than perfection. They scrapped, sanded, primed and finished the job in short order and it was a pleasure to watch these old decks look brand new again. There is no question that their work has added value to our home and for that, we thank them. We wholeheartedly recommend them!"

"He offered to powerwash my house, gutter edges, concrete floor of front porch for $250. He also wanted to show me how my deck would look if he powerwashed it, too, and actually powerwashed the entire thing. I asked him how much did it cost to powerwash the deck and he said, no worry, if I wanted to add something it was up to me. He was alone doing this all himself and stopped only to change nozzles and attachments. He powerwashed my house, trim, the porch floor, a plastic shed that had green algae on it, my deck, walk, and another concrete pad that I put my trash cans on. He also got on my roof and removed some fallen limbs and leaves that collected in recesses. I wrote him a check for $400 and still wasn't sure I gave him what he earned, he did that great a job. I plan to hire him again."

"Matt and his crew built the front porch last year. Like before they were clean, friendly and did superb work on the deck. I’m just sorry we don’t have another deck to rebuild! This deck will outlast us and I highly recommend them for future work!"

Deck Maintenance FAQs, answered by experts

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. 

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.

When installing deck boards, screws are generally a better option than nails. Screws offer superior holding strength over time, keeping the boards securely in place. In contrast, nails are more likely to pop out, which can create a tripping hazard. While you can use either, we recommend using 3-inch galvanized deck screws. To minimize the risk of cracking the wood, it's a good practice to drill small pilot holes before driving the screws into the deck joists.

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.

Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions.
