"They came on time, did the job, cleaned up, and left. They knew we had an attic door in the doctor's exam room so they entered thru the garage attic door but when they blew the insulation in, they didn't cover or protect the other attic door. Insulation fell in thru the cracks all over the technician who was working with the doctor. Since they knew the door was there I wish they had kept insulation from flying in. Otherwise I think they did a great job. It certainly made a difference in the temperature of the building on hot days."

"Omar and team did great work. Old insulation was removed and ceiling penetrations sealed on the first day with the new insulation installed on the second day. Omar was onsite the entire time and actually did the new insulation install. I was pleased with the quality of work and recommend."

"Everyone from sales to installation is great to work with. Friendly, professional, and genuinely interested in doing what was right for our home. Chris and his crew removed old insulation, sealed around vents, and installed new MILO insulation. We had 2500 square feet of attic space that the job took 2.5 days to complete. The entire team was respectful of our property, everything was cleaned up after each day. Chris was excellent to make sure everything was completed properly, any concerns he took care of them. Highly recommend Milo Insulation."

"My experience with Energy Attic USA went really well. They were very good price wise. They did a good job and they’re the only company that I find that would do a reading and barrier that actually use a metallic foil reading barrier that they would put in instead of spray. That’s what I wanted. It’s supposed to be much better. It’s all under insulation."

"The folks at DFW Home Insulation were great from start to finish. Allison handled all the scheduling and was very responsive. Jeremy came out for an estimate on Thursday, was prompt and professional, and had a quote ready right away. It was a very competitive so I signed up and they were able to come out and install my new attic insulation 2 days later. The day of the install they were were very prompt. The install took a little longer than expected because my house required some additional prep work, but they communicated with me about the extra time needed. Overall very pleased with the process and would absolutely recommend this company to anyone looking to have extra insulation added to their attic."

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.
