"Excellent experience! Had blown-in insulation added above an attached garage. Attic Fanatics has competitive pricing, quick response and lead time, and even allows payment via credit card. They even stayed after the job to help me put some boxes back up in the attic. Highly recommended!"

"We previously had Top Gun Attic Pros replace the fiberglass insulation in our house attic. The work was incredible, the product was perfect and they were great people to work with. We were so impressed that we told our contractor that we would select our own spray foam installers (of course it was Top Gun Attic Pros) for the barn we were building. Once again John and Top Gun exceeded our expectations. One thing I didn't mention was that their pricing was VERY competitive, but I would have paid a premium for their quality of work."

"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."

"S.R. Insulation was great from start to finish. They are the only one from Angies List to actually come out to see the project and ask questions before providing me a solid quote. They were at the job site the day & time they first suggested (a rarity it seems these days). Then they said they could turn around the project within a week, and they showed up on the date/time again and did the work. Had great work ethic and care, cleaned up after themselves, etc. Would highly recommend them for spray foam insulation jobs. English is a little rough but keep trying - they are worth it."

"I am extremely pleased with MILEX (MILO insulation). Work was done June 7 & 8, 2021. I have noticed a significant improvement in my home. Very professional, on time, worked nonstop except for a lunch break the first day (removing all old insulation- it was a MESS!). Worked nonstop the 2nd day - blowing in the insulation. I donâ  t hesitate to recommend to anyone and everyone"

"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."

"Iâ m so glad I chose J & E for my underfloor insulation project. Jesse was quick to respond, quick to provide an estimate, a great communicator and patient with my questions. He spent all day working in tight spaces but made sure the job was done properly - and even gave me more insulation in some areas. And they are family owned. I would use them again. Thanks J & E."

"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."

FAQs for insulation service projects in Decatur, 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.
