"Needed a solution for a room above a garage that was hotter than the rest of the upstairs. It was recommended to add insulation to the garage ceiling, air seal the attic, and add additional insulation to the attic. Since then, the room above the garage has been the same temperature as the downstairs. Great work and wonderful solution. Price point came in on average $1000 less than most quotes we received."

"Behr was fantastic! Nick and Dakota were extremely professional and provided a fair quote. They removed the old insulation, installed new insulation in my attic, and sealed all the gaps to help improve my heating efficiency. I have nothing but positive things to say about their work."

"My wife and I were so pleased with Chris and his team from the work on our crawl space that we hired them to remove and install new insulation in our entire house. Due to a previous leak in the roof the insulation wasn't effective. All About Energy Solutions came in and removed all of the old insulation and put new insulation in. They also added a radiant barrier. Chris is extremely knowledgable and passionate about what he does and wants to teach you about the benefits of the solutions they provide. This has been the second job we have hired Chris for and wouldn't hesitate to hire him or recommend him. Chris continues to go above and beyond for us."

"Ralph Bertrand from Home Genius Exteriors came out to thoroughly examine our roof. Ralph showed us many photos & a video of our roof, outside & inside. Ralph took the time to answer any questions we had. He explained the various products used & levels of warranty available. We really appreciated the time Ralph spent explaining everything to us, all without pressure to buy. The day of install arrived & the team was on time & ready to work! One thing we liked was that there was someone there from Home Genius Exteriors during the whole time of install. Richard Bowan, the Install Manager, was there to oversee everything & he did an amazing job. They placed large tarps over all our landscaping & got right to work. Rich kept us updated on progress throughout the day & answered any questions we had. In addition to the new roof, we also had new gutters with leaf guards & downspouts installed. When the work was completed, we walked around the house with Rich. Everything was completely cleaned up; there was nothing left behind or out of place. Our home looks amazing. The new roof, gutters & downspouts really look beautiful. We loved our experience with Home Genius Exteriors, especially working with both Ralph & Rich. They were so professional & knowledgeable. We would recommend them to others & if we needed additional work, we would definitely call Home Genius Exteriors."

Insulation FAQs, answered by experts

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’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’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

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.

Spray foam insulation can last between 80 and 100 years, depending on the type. Closed-cell spray foam is more durable, while open-cell foam is more susceptible to moisture damage and deterioration. It's important to consult a professional installer to understand which type of foam will be used and its specific longevity. Additionally, be aware that some spray foams can damage plastic piping, so if you have PVC or CPVC pipes, discuss this with your installer.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.
