Q: How do I flatten a cupped deck board?

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

Q: Can you add an under-deck drainage system to an existing deck?

• <div><p>Yes, it is possible to add an under-deck drainage system to an existing deck by retrofitting it to the structure. This process may require some prep work. For example, many drainage systems are installed on top of the deck joists, which would require you to remove the decking boards and railings first. To avoid this, you could opt for a below-the-joist drainage system. For best results and to ensure proper installation, it is recommended to consult a professional. A pro can inspect your deck, make any necessary repairs, and then install the drainage system correctly.</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>

Q: Do you need a permit to build a deck?

• <div><p>Whether you need a permit depends on the deck design and local regulations. Most areas mandate a building permit if the deck is over a specific height or if it's attached to a pre-existing structure. Shorter, freestanding decks may not require a permit, but you should check with local zoning ordinances and your homeowners association for specifics.</p></div>

Q: What inspections are needed when building a deck?

• <div><p>Decks require several inspections during and after the building process, but the specifics vary depending on where you live. Most areas mandate that decks comply with local building codes and safety regulations for the foundation, framing, and structure. Some pros recommend a footing inspection, which verifies the depth, width, and location of the various footings to ensure they offer enough foundational support. </p></div>
