"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"

"The representative was very knowledgable about the scope of work. I called him for the replacement of the attic insulation due for rats. I had pest control guy tell me my attic insulation had to be replaced. The rep, Guy, told me that wasn't what I needed. He told me that replacement the attic insulation would not solve my rats. He gave me names of good pest controls. Guy said to contact them before spending thousands of dollars for rats in my attic. Thank you Guy."

"I can't thank these guys enough! They gave us a great deal and went above and beyond what we had hired them to do. They are going to come back out and take care of a few other things that they can do besides insulation. I can't recommend them enough. They are very punctual, professional, and very friendly. Even our dogs approve of them! Even before they were finished, I already noticed a VERY big difference in the temperature in the house. Instead of the AC running all day and it being 6-10 warmer than I prefer, it stays at the temperature I want it. The AC runs 1/4 of the time instead of running all day."

FAQs for insulation service projects in Duncanville, 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.
