Q: Do I need to seal the underside of a deck?

• <div><p>Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.</p></div>

Q: Can I build a pool deck myself?

• <div><p>Yes, you can build a pool deck yourself, but it takes precision, a lot of time, and many specific tools. You&rsquo;ll need to create a deck plan, be careful with measurements, cut each piece of wood, secure the pieces properly, and ensure the deck meets building codes. Building a deck around a pool is a rewarding DIY, but it&rsquo;s time- and labor-intensive, so thoughtfully consider your abilities and the time you have before embarking on this DIY.</p></div>

Q: Is Trex decking an eco-friendly material?

• <div><p>Trex states that its <a href="https://www.angi.com/articles/what-is-trex-decking.htm">Trex decking</a> is an eco-friendly composite material made of 95% recycled or reclaimed materials (including plastic and wood), making it a sustainable brand of choice. According to the company, Trex is one of the largest plastic bag recyclers in the U.S., with each 500-square-foot Trex deck containing about 140,000 recycled plastic bags.</p></div>

Q: Should deck boards be spaced or tight?

• <div><p>Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation. </p></div>

Q: Should deck boards be nailed or screwed?

• <div><p>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.</p></div>
