"They were wonderful guys, respectful, friendly, hard working and got the job done. When Matt first came to my house to see the job, he was thorough and explained everything to me. He took pictures in the attic to show me what he was saying. It was scheduled during that artic weather and they still worked and got the job done even though they had to be in that cold all morning. Matt wanted to make sure it was right. Made sure they protected my home and cleaned up after. Really great company !!"

"Reeds reinsulated our attic of 70 years. The former insulation had settled well below the rafters. The work crew vacuumed out the old, sealed around all openings to lights, fans, etc and then blew brand new fiberglass insulation to knee depth. We now have lofty, R-40 rated protection in a 2600 sq' house that heats evenly through out. Reeds will return to encapsulate our crawl space in one month!"

FAQs for insulation service projects in Johnson City, TN

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.
