"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"I had Javier check to see if I needed new underbelly insulation on our mobile home. I could not crawl under the trailer to see if this work was needed. He could have taken advantage of the situation, but said all I needed was two patches and ground cover. They actually installed three patches with no additional cost. Honesty, integrity and professionalism are key to this business."

"I can?t say enough good things about PeakPro Insulation! Before they came out, my attic wasn?t insulated at all and my house constantly fluctuated in temperature. When their team arrived, they introduced me to solar radiant barrier insulation. The difference was noticeable immediately. After the job was done, every room in my house finally felt consistent in temperature, and even my attic felt cooler while they were working up there. On top of that, they left the attic looking beautiful and clean. Highly recommend"

"It was great; they took only a weekend to do my living room, kitchen, dining, library and stairwells. They were covering some dark custom colors so it took multiple coats. I liked them so much I hired them again to paint my kitchen cabinets too. Will definitely recommend and use them again!"

Insulation questions, answered by experts

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.
