Q: What’s the average cost to replace a 20-by-20-foot deck?

• <div><p>Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.</p></div>

Q: Can a deck be turned into a room?

• <div><p>Yes, transforming a deck into a sunroom is an absolute possibility. <a href="https://www.angi.com/articles/how-much-does-sunroom-cost.htm">Building a sunroom</a> involves framing in the deck area with walls, adding windows, and affixing a roof. This project is not an easy task, but it does provide a stylish addition to your house. Not all deck designs support this type of renovation project, so consult a professional deck builder before beginning. </p></div>

Q: What is the best decking material for pool decks?

• <div><p>The &ldquo;best&rdquo; material is in the eye of the beholder, as each common decking material boasts its pros and cons. Poured concrete is the best budget-friendly option, but composite wood brings high-grade aesthetics without breaking the bank. Wood is the most traditional material, but it requires more maintenance than some other materials. In other words, do your research before settling on a deck material to find the one that&rsquo;s best for your pool. </p></div>

Q: What kind of base or foundation is required for composite decking?

• <div><p>Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.</p></div>

Q: What is the proper and most comfortable height for a stair riser or deck step?

• <div><p>The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.</p></div>

"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it. Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "
