"After contacting Jace, he came and did an assessment. He sat down and gave us a very fair bid on adding blown in insulation to our attic. We accepted the bid and he and his partner were back in a week’s time. They were very timely on arriving and were finished in their estimated time. They cleaned up the area very good. I highly recommend this company for any insulation needs."

"The consultation went fine. He was very thorough and looked at everything and talked us out of things that we did not need. I thought he was fair and honest. He did provide the consultation for free. He contacted us right away and got together with us in a day or two. The quote was quick and he followed up a month later. I have no complaints. We are not going to be doing anything this year but would consider him in the future."

"Butch was prompt on coming to our home and getting us an estimate before he left. They arrived on time, got their work done and did a nice job of cleaning up. It's too early to grade how the new insulation is doing as far as comfort and energy efficiency."

Insulation FAQs, answered by experts

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

Vapor barriers in attics are a bit outdated and most areas no longer recommend them for attic spaces. For vented attics, the best method is usually to install drywall and cover it with latex paint before attaching insulation fiberglass, cellulose, or foam insulation. When renovating an attic to use as a living space, a contractor can guide you on the best way to cover insulation.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

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.
