"Troy from Kuuma Insulation was absolutely fantastic! He came to my home to give me an insulation quote on his way home from vacation. He was very kind, professional, & honest. He gave me a straightforward quote, no fluff, and came in with a lower price than anyone else could offer. He also completed some additional insulation work for me and he was still cheaper than competitors! I highly recommend Troy & team for your insulation needs! 👍🏼👍🏼"

"We initially had them add attic insulation up to current new construction code as well as seal the perimeter. This year we added insulation in our crawl spaces and sealed the basement using spray foam. Our 35 year old home is now about as efficient and tight as a new house. We got the owner to evaluate our conditions, get a detailed written estimate before the work was done. The crew was thoughtful, detailed work and great cleanup. They took time to answer all my questions."

FAQs for spray foam insulation projects in Harrisburg, 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.
