Q: Can I use fiberglass insulation to soundproof a room?

• <div><p>We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that&rsquo;s part of your living space. <a href="https://www.angi.com/articles/diy-dangers-fiberglass-insulation-hazards.htm">Fiberglass insulation is dangerous</a>, and the installation process is hazardous. It is also harmful to the environment. When there are so many newer, healthier non-fiberglass alternatives in the market, the lower cost of fiberglass insulation simply doesn&rsquo;t justify the harm and danger it poses.</p></div>

Q: Can I insulate my walls without removing drywall?

• <div><p>It is possible to insulate your walls without removing drywall, but it&rsquo;s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there&rsquo;s insulation in your wall already that can remain in place. <a href="https://www.angi.com/articles/spray-foam-insulation-cost.htm">Spray foam insulation costs</a> more and isn&rsquo;t always a viable option, but it&rsquo;s a better insulator. Call in an expert to help decide which is right for you.</p></div>

Q: What’s the most cost-effective way to insulate windows?

• <div><p>If you have bubble wrap lying around the house and you don&rsquo;t care about the odd look, taping bubble wrap over a window is a very affordable way to insulate it. Another inexpensive option for insulating windows is to add new caulk around the glass. This step quickly cuts down on air drafts for older windows, and a tube of caulk only costs a few dollars. Adding plastic shrink film around the glass is another cost-effective option. You can purchase a kit of plastic film for a few dollars per window.</p></div>

Q: Does plaster insulate better than drywall?

• <div><p>Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.</p></div>

Q: Should I remove old cellulose insulation before installing new insulation?

• <div><p>Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there&rsquo;s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you&rsquo;re unsure how to assess the presence of mold or mildew, talk to a <a href="https://www.angi.com/companylist/mold-testing-and-remediation.htm">mold remediation specialist near you</a>.</p></div>

"Through Angie's List, I was pleased to discover Comfort Pro's was having a three day special so I called and was able to get service within hours! The tech arrived on time - actually 15 minutes earlier which worked out great for me. He showed up in a clean company rig and presented himself well in his clean company uniform (yes, outward appearance is important to me; shows pride and commitment toward quality work). He asked questions regarding the usage of the units and from there I was able to communicate my concerns or rather my confession that my A/C had not been serviced in years! He did a great job of explaining how the units work and what to do to keep it running efficiently (regular scheduled maintenance, cover A/C unit in winter, etc.). By the time he completed the work, his uniform carried much of the furnance and a/c units dust and dirt:-) He was thorough and professional. I'll be scheduling my next service with Comfort Pro's for sure=D

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."
