Why does my deck pop and not my neighbor’s?

• <div><p>Your deck may pop, and your neighbor’s deck may not for a number of reasons. Whether or not a deck pops will depend on how it was made, the conditions it’s exposed to, and the materials. Improper spacing is a common reason for increased pressure between deck boards. Moisture penetration is another. </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: Should there be a gap between the house and the deck?

• <div><p>In most cases, there should be a small gap between the house and the deck, usually no more than &frac12; to &frac34; of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the <a href="https://www.angi.com/articles/5-common-deck-problems-and-solutions.htm">most common issues with decks</a>.</p></div>

Q: Why does my deck pop and not my neighbor’s?

• <div><p>Your deck may pop, and your neighbor&rsquo;s deck may not for a number of reasons. Whether or not a deck pops will depend on how it was made, the conditions it&rsquo;s exposed to, and the materials. Improper spacing is a common reason for increased pressure between deck boards. Moisture penetration is another. </p></div>

Q: What happens if you build a deck without a permit?

• <div><p>Building a deck without a permit could lead to fines for both the homeowner and the contractor. The exact penalties will depend on your state and municipal building laws. You might also be required to remove the deck and apply for a permit before you can build another. While it might be tempting to skip the permit to save a few bucks, it&rsquo;ll cost you much more if you&rsquo;re caught.</p></div>

Q: How long do you have to stay off a deck after sealing?

• <div><p>For the best results, stay off of your deck for at least 48 hours after sealing it. Giving the sealant at least two full days to cure ensures it can fully penetrate the wood, giving you the most protection from sun and weather damage later on. Walking on the deck too soon can prevent it from properly curing and cause your deck to weather prematurely.</p></div>

Deck Cleaning questions, answered by experts

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.

In most cases, there should be a small gap between the house and the deck, usually no more than ½ to ¾ of an inch. This space allows water and moisture to flow through instead of pooling against the side of your house. It also lets flashing protect your siding from runoff, which is one of the most common issues with decks.
