"My wife and I were very pleased with the team that came out to install the MILO Insulation at our home. We found them to be very professional and courteous. They worked quickly and quietly to install the MILEX insulation and cleaned up after themselves. Overall it was a fine job. We would highly recommend MILO Insulation of Texas â Denton."

"The team at NxT Level Insulation did an exceptional job with our attic insulation. Dillon was incredibly helpful in explaining the process and the crew he led was efficient and professional. We're noticing the difference already - the temperature is more consistent throughout the house, and our HVAC is running much better."

"I had my attic areas sprayed with foam insulation by Southern Twist Spray Foam. The owner, Marc, was incredibly helpful in explaining the process and offered fair pricing. He was easy to work with and down to earth, making the entire experience smooth and stress-free. Since the installation, I've noticed a decrease in my electric bill during the summer months. I am a very happy and satisfied customer and highly recommend Southern Twisted Foam Spray for anyone looking to improve their home's insulation. I know they offer other services such as lifting driveways etc with foam, but we didn?t need that service yet. Thank you, Marc, for your excellent service!"

"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."

"Great job, thoroughly cleaned both plenums (in and out), reattached ducts after cleaning (from plenum down and from duct grills up), duccts repositioned in the attic, blower disconnected and taken down for thorough cleaning. All furniture and stuff was vinyl-sheet covered. Vents were repositioned correctly. House smells fresh now. Fast, clean, efficient. Reasonable also, easy to work with. Would not hesitate to recommend this company. Thanks a lot"

FAQs for insulation service projects in Greenville, TX

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.
