Q: Can you build a deck and not attach it to the house?

• <div><p>Yes. Freestanding or floating decks are exactly what the name implies&mdash;structures with their own support beams. You can <a href="https://www.angi.com/articles/how-to-build-a-deck.htm">build a deck yourself</a> and place it next to a house for the illusion of a connected deck without the hassle. Or you can construct it in a separate part of your yard for a dedicated outdoor entertainment space. For the purpose of removing a freestanding deck, the steps are the same as an attached deck, but you don&rsquo;t have to cut the deck away from the home. </p></div>

Q: What is the life expectancy of a PVC deck?

• <div><p>A quality, well-maintained PVC decking can last 30 to 50 years. It&rsquo;s known for being one of the most durable <a href="https://www.angi.com/articles/types-of-decks.htm">types of decking</a> materials, with composite decking having a 25- to 30-year average lifespan and some softwood deckings only lasting 10 to 15 years. Luxury hardwood decks like Ipe may last longer than PVC decking, but they can cost more and require more maintenance.</p></div>

Q: Is it necessary to skirt a deck?

• <div><p>No, it isn&rsquo;t necessary to skirt a deck, but investing in the cost to install deck skirting can bring more value to your home. Not only does deck skirting make the deck look more complete, but it can also turn otherwise unused space beneath the deck into useful storage space.</p></div>

Q: Is pressure-treated decking worth it?

• <div><p>Pressure-treated decking may be worth it if you want a natural, insect- and rot-resistant decking material that will last for decades with proper maintenance. As such, it&rsquo;s a much better option than untreated pine. Alternative wood decking materials like cedar and redwood tend to be less durable and more expensive. Some homeowners prefer <a href="https://www.angi.com/articles/which-best-decking-material-wood-or-composite.htm">composite decking</a>, which is a low-maintenance alternative to wood but is also more costly.</p></div>
