"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 sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Costs depend on insulation material, labor, accessibility, and whether existing insulation requires removal.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.
