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: How much does a 12x20-foot (240-square-foot) deck cost?

• <div><p>For a 12x20-foot (240-square-foot) deck, you can expect to pay between $7,200 and $14,400. This cost is based on a general price of $30 to $60 per square foot. The final price will depend on factors such as the decking material, design complexity, deck type, location, and local labor costs. Keep in mind that add-ons will increase the total; for example, adding an under-deck drainage system to a deck of this size could cost an additional $7,700.</p></div>

Q: What is the standard spacing for railing spindles or balusters?

• <div><p>Most building codes require that railing spindles (also known as balusters) on decks or stairs be spaced no more than four inches apart. This safety standard is often called the '4-inch sphere rule,' which means a sphere with a 4-inch diameter should not be able to pass through the opening between balusters. This rule is in place to prevent small children and pets from slipping through the railing. For the same reason, the space between the bottom rail and the deck or floor surface should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is essential to check your local building codes to ensure compliance before starting your project.</p></div>

Q: Do I need to sand a deck before repainting?

• <div><p>Always sand a deck before repainting so the wood is smooth and ready for paint. While you do not need to fully remove paint before repainting, sanding helps remove any areas with weather and sun damage. Sanding also helps remove chipped or flaking paint and opens the wood pores to improve paint adhesion.</p></div>

Q: Will regular maintenance stop decks from warping?

• <div><p>Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.</p></div>
