"Sheldon and his team were everything you could want in a painter. Prompt communication, fair price, good advice and excellent work. They went above an beyond to fix the little things that they found. No extra cost. They even moved the wood pile away from the deck and restacked it. High marks across the board."

Deck Repair FAQs, answered by experts

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. 

Yes, deck pier blocks can be used as an alternative to traditional deck footings, especially for smaller or low-to-the-ground decks. Unlike poured concrete and buried post footings, deck blocks do not require digging or pouring. However, their use is dependent on local building codes. Some areas, particularly those prone to high winds, earthquakes, or hurricanes, may not permit the use of deck pier blocks. It is essential to consult your local building codes before choosing them for your deck project.

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.

Applying too much sealer to a deck might seem like extra protection, but it can cause more harm than good. Wood is a porous material with a limited capacity to absorb liquids. When you go overboard with sealer, the excess can't soak in and instead forms a film on the surface. This leftover layer is prone to peeling, cracking, and trapping moisture, ultimately defeating the purpose of sealing in the first place. 

Floating decks are a cost-effective and versatile option, but they come with some compromises. Since they sit on smaller footings instead of being deeply anchored, they’re more likely to shift over time, especially in areas with heavy rainfall or freeze-thaw conditions. Their low-to-the-ground design makes them more susceptible to moisture buildup and potential water damage.
