"My only issue with the blown insulation was that the company blew the insulation over the few items in the attic. My daughter was at the house when it was done and said they didn't ask if it should be moved. They installed measuring tape in different places throughout the attic to ensure the proper depth was achieved and pointed these out when done. They also installed the air vents on the angles to ensure the air flow was proper."

"Matthew did a thorough quote at my house shortly before Thanksgiving. Matthew was very professional, on-time and friendly. The technology was impressive as you could see the ?cold spots? around my attic space. I plan to execute the job after the holidays. I highly recommend Matthew and Insulation Commandos if you need any insulation related work."

"Eddie fully explained the benefit of the planned level of insulation for our attic, uses quality Owen's Corning fiberglass blown in insulation and recommended adding an roof vent attic fan to remove heat/moisture in the summer and moisture in the winter. Currently, we have passive eve vents and roof ridge vent. Cooling inside of the roof with air flow should help extend the life of the shingles by removing stagnant hot air. We chose an electric roof vent fan rather than solar because of the # of cloudy days in our area and humidity. Everything was done quickly on scheduled time, all contacts were professional, kept our home as clean as possible and swept up loose insulation. Pricing was very competitive plus we qualified for TVA energy rebate."

"James and his crew did a phenomenal job with the insulation job! His communication was great. Very honest and upfront about what can and can’t be done. No trying to finesse an upsale or anything like that. I'm very glad we went with James and I'd highly recommend him to anyone looking."

"The Moore brothers were great. They satisfied my Home Owners' Association with a detailed proposal within an hour of inspecting the job. They itemized and described the work, which included cleaning off the mold, replacing insulation, repairing joists, encapsulating the crawlspace, and creating a French Drain on the exterior of my unit to redirect the rain. They also set up my dehumidifier in the space with a wireless meter I can read from inside . Their price was in line and they did everything they promised in good order, good humor, and respect. Three other companies bid and were not even close... in promptness, plan, OR price. I highly recommend Jon and Danny Moore."

FAQs for insulation service projects in Harriman, 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.
