"This whole experience has been nothing but a pleasure with all that have come out to put a new roof and gutters on and to also install insulation in my attic. The two gentlemen (Mike and Ethan) who did the insulation were outstanding. Curteous and very very nice young men and a pleasure to talk to. They did an outstanding job and I would HIGHLY recommend this company when it comes to having any home exterior jobs done. If I could give them a 100 stars I would!!!!"

"JOB: Install Blown-In Insulation into an un-insulated attic space. The job was estimated, appointment made and kept. Job was re-evaluated on install date to provide additional insulation on (1) interior wall. Job completed on appointment date. Workers were conscientious: placed covering on floor for "path" to upstairs attic to walk on, and removed when complete. Work was performed timely. Completed Job: The insulation has made a tremendous difference. My upstairs area of the house is now livable! I'm very happy with the entire job! Would definitely rehire Thermal Comfort to do any future insulation jobs."

FAQs for spray foam insulation projects in Altoona, PA

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.
