"Owner, Jim Mass, responded promptly to set up a personal visit to explain the process and options to myself and my wife. Once the work was scheduled; crew arrived on time and work, including total clean up, was completed within the estimated time of less than day. All was completed within 1 week of the owner's initial visit. I would definately recommend Insulation Specialists to friends, which I have done."

"Thermal Comfort exceeded my expectations for scheduling my project, and the quality of their work is excellent. They did a great job of protecting everything prior to application, and the cleanup was done well. As a retired architect and professional engineer, I expect and watch for quality, and was very pleased with this company. I recommend this company to anyone requiring a foam insulation project of fine quality and a good value."

"These guys came out right away, gave me a fair price and did the job great ! The toughest part was removing old insulation, getting it out of my house and cleaning it all up. They did all that and sealed up my basement tight ! Using their foam insulation they filled in all gaps. And they did it in one day ! We now notice our house stays a little warmer and no more mice ! Kyle and his crew were fantastic and I recommend them highly. -- Alan B - Sun Prairie"

Insulation questions, answered by experts

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

If you have blown-in insulation, using an insulation vacuum will quickly and easily suck up all the insulation. Many come with built-in HEPA filters for added safety. While some people suggest breaking up large batts and feeding them into the vacuum, this can expose you to more fiberglass fibers. With batts and rolls, carefully removing them and placing them into garbage bags is a better process.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.
