How do I flatten a cupped deck board?

• <div><p>To flatten a cupped deck board, start by ensuring it’s dry. Then, try flipping the board over so the cupped side faces down and reattach it. If that’s not possible, you can use screws to pull it tighter to the joists or plane the edges slightly to reduce the cup. It’s best to replace severely cupped boards.</p></div>

Q: How do I divert water from under my deck?

• <div><p>To maximize the utility of space under a deck, it&rsquo;s important to keep this area dry and clean. One way to prevent the area from becoming too wet is to install an under-deck draining system. This affordable home upgrade channels water away from the deck and provides usable space for storage or a functional area below a second-story deck. Not only will this be a useful maintenance upgrade, it can boost your home&rsquo;s property value.</p></div>

Q: How long does it take for composite decking to warp?

• <div><p>Composite decking may never warp, or it may warp quickly. Several factors can influence the rate of warping, including the material's quality, installation method, and installation location. Generally speaking, high-quality materials that have been installed properly are drastically less prone to warping. </p></div>

Q: What grit sandpaper is best for sanding a deck?

• <div><p>Start with a 60- or 80-grit sandpaper when sanding a deck, though this could change depending on the type of wood that comprises the deck and how smooth you want the overall finish. If you prioritize a smooth final finish, progress to a finer grit like 120 or 150. Avoid ultra-fine grits for traditional sanding, as it could close up the wood pores and make it harder to apply a finish down the line.</p></div>

Q: Do you need a permit to repair deck boards?

• <div><p>No, you don&rsquo;t need a permit to repair and replace a few boards on an existing deck. However, if you&rsquo;re making structural changes to the deck or tearing down the old one and building a new one, you will likely need a permit. Check with your local municipality for the regulations and rules in your area, or ask a local contractor <a href="https://www.angi.com/articles/how-hire-deck-building-contractor.htm">who builds decks</a> for advice.</p></div>

Great alex went above and beyond to make sure the job got frozen and we were happy with it even though there were more than a couple hiccups with unknown problems popping up during the install process. He knew what to do and worked through them with us. Would happily hire again and recommend!
