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: What’s the difference between pressure-treated decking and other decking types?

• <div><p>Pressure-treated wood contains preservatives that give the material internal protection from rot and pests. Untreated lumber won&rsquo;t last more than a few years unless you choose a more expensive wood, like cedar, that naturally stands up well to moisture. Composite decking can outlast wood but is more expensive and doesn&rsquo;t look as natural. Keep in mind that you&rsquo;ll need to seal any exterior wood product to protect it from the elements and other forms of external damage.</p></div>

Q: Is composite decking better than real wood?

• <div><p>Whether composite decking is better than wood depends on your priorities, especially regarding budget and maintenance. Composite decking offers superior longevity (30 to 50 years) and durability, and it is low-maintenance, requiring no sanding, staining, or sealing. In contrast, wood decks typically last 10 to 30 years and need refinishing every few years. While the upfront cost of composite is higher than wood, the reduced maintenance can lead to long-term savings. If a lower initial cost is the primary factor, wood is the more affordable choice.</p></div>

Q: Does a deck have to be perfectly level?

• <div><p>A deck doesn&rsquo;t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems. </p></div>
