"Jonnie was very nice and did a nice repair on my parent’s black chain link fence that a tree had fallen on. He ended up driving A LOT further to find the parts needed for the repair, but he did not increase his original quote. Thank you, very much! Sorry I didn’t take after photos but it looks fine."

"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

He got here on time and got the job down in an excellent manner. He was professional in every aspect of the work and made sure I was happy with the job he did before he left. I would use him for future work and will definitely recommend him to others."

FAQs for spray foam insulation projects in Mars Hill, NC

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.
