"The insulation was installed as promised on the appropriate date, we are satisfied with the insulation. The problem was the work crew was extremely careless. There was foam insulation over the front door, front windows, they have to take off your siding in different areas, I am still picking up hundreds of screws. Foam insulation is still being picked up in my front mulch. Tarps were supposed to be laid and were not put down. My basement was another problem, it is finished with the Dow Corning type system, again, tarps were not used. There is foam insulation in three different areas that do not come off the cloth walls. When we started to point out these issues, they seem very concerned. The crew came back out and power washed the front of my house. The foam did not come off. They used our water for their power washer, left it running which created an ice dam in our back yard. On several occasions, we have tried to get some form of compensation for the basement and they are always looking into it; We are satisfied with the insulation, but everything was such a mess it was not worth it. I would look at other companies."

Insulation FAQs, answered by experts

You can buy pipe insulation materials in your local hardware store or in major home improvement stores. You can also shop for insulation online, where you may be able to more easily buy in bulk. When shopping, make sure you know your pipe's dimensions so you can buy the correct size of pipe insulation materials for your pipes.

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.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures.
