"This work was performed in Groveland, FL, 34736. Capstone Insulation was great. The VP came out, went through the attic, and described the work to be done. This included thermal imaging to find air transfer locations, air sealing between the attic and living spaces, installing baffles over the inside soffit vents, installing and air sealing recessed lighting covers (for fire safety), installing new insulation, and pre- and post-insulation air flow testing. The installation crew was very competent and friendly. They performed the initial air flow test and all the pre-insulation work on day 1. They came back the next day to install the insulation and perform the final air flow test. The VP provided me with a video of the Day 1 work and a video of the final outcome. All of this work was done at a price point that I thought was reasonable (about $2/sq. ft.)."

"They came out to inspect my property. They told me I didn’t need their services and my house was insulated more than enough. They could’ve sold me the world, instead they were extremely honest and polite. Their prompt and professionalism is unsurpassed and I would recommend them with all my heart"

"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

Insulation FAQs, answered by experts

Actually, condensation can mean that your windows are more energy efficient because the seal keeps cold air out and warm air in. In some cases, windows with poor seals can lead to more condensation, but they may allow the cold and warm air to mix and reduce condensation. If you’re worried about whether or not your windows are properly insulated, have a pro assess them.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

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.

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.
