"Prodent Homes did an excellent job with our attic remediation. They removed the old insulation, sanitized and re-insulated the entire attic. The owner David was easy to communicate. The crew lead Jose was very experienced and communicated well. The job was done professionally. We are happy with the results and will use them again if we have another insulation job."

"Comfenergy was very professional thorough from the in-person estimate thru installation. Even though we didnt have a full energy audit, they still go over your entire home and tell you what should and what needs to be done. Some of the little things we did ourselves, or had our handyman. Then Comfenergy did the big part, seal and insulate the attic. We still had late 80's insulation and never a sealing done. It ended up being over an 8 hour project. They were not the cheapest estimate, but definitely the most in-depth review and recommendations provided. The two man team that did the actual work were very professional, showed us the work as the progressed, and good clean up job after all was done."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"I had multiple estimates and Fifth Fuel was the most professional and reasonable. Josh came to my house, took pictures of my attic and explained the different choices of insulating the attic. He provided an estimate in writing the same evening. The installers arrived on time, sent me photos of the before and after. They left the house clean with no debris. The result is a huge improvement in the temperature between the upstairs and down. I couldn’t be happier with them! Outstanding!! Thank you!"

"From the start of the estimate with Jon to the insulation project with the Team Leader Carlos, the project went well as expected. Jon was very professional and knowledgeable. He did not try to up-sale services I did not need, and I appreciate his honesty. Jon went over the appropriate insulation for the attic and the garage ceiling to bring our home to a comfortable level. Carlos and his crew did a great job communicating with me while performing the insulation. Carlos immediately notified me of a leak he discovered from the attic fan and temporarily paused the work on the attic and moved to the garage ceiling insulation while I addressed the leak. As a customer, the only comments/suggestions I would give to the crew is: (1) make sure they keep their tools and materials off the lawn (2) make sure the plastic wraps from the materials they use and trash does not get blown away to the neighbor's yard/driveway, and finally, (3) ask the homeowner which bathroom the crew can use while on-site. Overall, I am very happy with Comfenergy and their service. In fact, I have already recommended them to a curious neighbor."

"When my Dominion Home Energy Report showed that I â used 101% more electricity than average homes,â I knew it was time to do something! I read reviews and then reached out to several companies for an estimate to replace my attic insulation. Capital Insulation provided an itemized quote that was the best value. I was happy every step of the process from working with Karl on the estimate to scheduling the installation with Lisa and communication with the crew while they did the work. The installation was completed quickly, they cleaned up when done, and payment via bank transfer was simple through QuickBooks. I will gladly recommend Capital Insulation to friends and family."

"Kelvin, the owner of the business, did a fantastic job with my project. He answered my call, was able to come by to look at the project promptly, knew exactly what I needed done, and made this process very easy with a reasonable quote as well. I had plywood flooring down and he and his guys unscrewed it, moved my attic items around to get full access in stages and sucked out all the old insulation, while covering my stairs and hallways with drop cloths. They were clean, respectful, efficient, showed me what was happening along the way, and did a stellar job. They added foam insulation and blown-in insulation, reinstalled my flooring and left the job in very good condition. I am very happy to recommend them!"

Insulation FAQs, answered by experts

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

We do not recommend fiberglass insulation for soundproofing purposes, especially if you are working on a room that’s part of your living space. Fiberglass insulation is dangerous, 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’t justify the harm and danger it poses.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

When looking for a company who installs insulation, your best bet is usually to work with an insulation contractor or professional insulation company. If you can't find a local insulation company, working with a general contractor can be another option. No matter who you hire, always confirm that they have experience.
