Q: How much does it cost to fix a sinking deck?

• <div><p>The <a href="https://www.angi.com/articles/how-much-does-it-cost-repair-deck.htm">cost to repair a deck</a> is between <b>$900 and $3,500</b>, depending on the cause and extent of the damage. For example, fixing a sinking deck caused by pest damage can cost between $200 and $600, while replacing sinking boards costs between $500 and $4,000.</p></div>

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: Is it worth it to install a deck?

• <div><p><a href="https://www.angi.com/articles/how-to-build-a-deck.htm">Building a deck</a> is often worth the investment, not only because it provides more utility to your yard and gives you more space to entertain but also because decks tend to add value to your home. Keep in mind that second-story decks often require concrete footings, which means they will bump up your property taxes, while decks built on the first story generally don&rsquo;t require a permanent foundation and won&rsquo;t affect your taxes. Even with the tax increase, decks are usually a good investment in the long run.</p></div>

Q: What is the best grade of lumber for a deck?

• <div><p>When building a deck, #2 grade lumber is a go-to for several reasons. It&rsquo;s strong, budget-friendly, and works well for most framing and decking needs. But upgrading to #1 or Appearance Grade can give your deck that extra visual edge if you're after a cleaner, more polished look for high-visibility spots.</p></div>
