It&rsquo;s important to follow the codes and regulations set by your local and state governments, so your insurance rates can be properly calculated. You may need an insurance revaluation after your deck is completed. The best course of action is to speak with an insurance professional to understand how adding a deck will impact your home&rsquo;s insurance costs before you begin.</p></div>

Q: What is the best material or fill to put under a deck?

• <div><p>While you can use various materials like sand or even just soil, gravel is widely considered the best option to put under a deck. It provides excellent drainage and is resistant to water, fire, and pests. Gravel also helps anchor the soil to prevent erosion during heavy rain and acts as a built-in weed blocker, reducing regular upkeep. Furthermore, it is simple to spread, available in various textures and tones, and adds a polished look that complements any deck design.</p></div>

Q: Do composite decking warranties cover warping?

• <div><p>Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals. </p></div>

Q: How many footings do you need for your deck?

• <div><p>In general, you need a footing at each corner of your deck, and within 8 feet of each other. So, how many you need depends on the size and shape of your deck, plus any local building codes. It also depends on factors like the load capacity of your soil and the weight of your deck. You can find a footing calculator online or contact a pro for support. </p></div>
