Q: How do I know if my crawl space needs insulation?

• <div><p>Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they&rsquo;re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.</p></div>

Q: Do you need to insulate your basement?

• <div><p>Depending on where you live and the conditions of your basement, you may not need to insulate your basement. Your best bet is to talk to a basement remodeling company to find out what they recommend doing.</p><p>Insulating your basement can help improve your home's energy efficiency, but it will also increase the cost of your basement remodel project. The average cost of installing <a href="https://www.angi.com/articles/basement-insulation-options-and-costs.htm">basement insulation</a> is <b>$2,400</b>.</p></div>

Q: Can you put insulation on top of ductwork?

• <div><p>Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.</p></div>
