"I called Austin Insulation after checking with a few other local competitors. I figured since my name is Austin, these guys HAVE to be the best around. Rob was able to get the job done today within days of my initial call which was HUGE because everyone else was weeks to months out. I think people are passing Austin Insulation because of the small amount of Google reviews; don't make that mistake. They had the best price and fantastic service, please give them your business"

"I hired Thermal Solutions to spray foam insulate my pole barn and they did an excellent job. I got 4 quotes and theirs was the cheapest. They say never go with the cheapest, but I did because I wanted to support a veteran owned, local business, and after talking with Niko, I felt confident the job would be done right. I'm really glad that I did because they came when they said they would, they did it just the way that I wanted, and they did a great job of cleaning up when they were done. I highly recommend them for open and closed cell spray foam insulation jobs!"

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.
