"I've used Thermal Comfort a few times in the past to insulate entire homes, but this time I had a small job. Although this was a small job, they didn't treat it as one. From the start, I called Dason and he came to my property right away to look at the scope of work. I told him I'd like to get the work done ASAP. Although they were busy he squeezed me in, I was on his schedule within a week. The two techs, Randy and Walt were professional and got the job done in a timely manner. I will continue to use Thermal Comfort for my spray foam needs."

"Oscar was extremely responsive, professional and was able to complete the job in a timely manner. He was open and honest about the product he used. He removed the old rolled fiberglass insulation for us as well. I would recommend DeAndas to anyone looking to have spray foam insulation installed!!"

"Tyler was the first to respond to an Angi List search, came the next day, and told me that my attic insulation, while not perfect, wasn't in need of adding more. I appreciated his honesty, even at the cost of losing a contract. I recommend this company based on honesty."

"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"

"My whole experience with Thermal Comfort was wonderful. Normally I'm one of those people who build or repair something myself. I was very comfortable with Dason Schultz. He is very courtious and through. I felt his company would give me the bang for my bucks. His quote was by far the most affordable. When his employees showed up (ON TIME :) ) they immediately asked me what I wanted done and where. They worked as a team and were Great! Actually they went out of their way to do a Tremendous Job! Already two of my friends are looking into using Thermal Comfort as their Insulation Specialist."

Customers say: Quick response

"Specific project was attic, dense pack, and foam insulation. Very clean, friendly, and professional crew. Took the time to explain what they were doing, why, and what was wrong with what they found. Did a Focus on Energy assessment along with this work, recommended by Premier North, to make sure we let the science dictate the work. Very impressed with my overall experience."

FAQs for insulation service projects in Germantown, WI

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
