"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."

"My son recently purchased an older home that had very little attic insulation. After Rob's team finished adding fiberglass insulation the A/C turned off almost immediately and the home remained at 74 degrees even though it was over 100 that day. I was very impressed and plan to have them come inspect my attic next !"

"It was great! Jorge & his partner were very prompt, courteous, and efficient. I don’t have a really large attic but 3 other big companies quoted over $4000 to install insulation in my attic. North Tx Insulation did 13 inches of new blown in insulation for $1000.00. They were neat & in and out within an hour. I would highly recommend them!"

"They had a cancellation and moved my appointment up a day; that pleased me as we had a cold front blow in and temps were in mid-30's. Before they were finished I noticed my house was noticeably quieter. They worked for 1.5 hours and were finished with the cleanup. Since then I have been able to lower my thermostat 6 degrees and it's warmer than before. Thank you"

"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."

Insulation FAQs, answered by experts

Yes. Bathroom insulation requires a vapor barrier. As a matter of fact, bathrooms and kitchens are the two areas of the home that should always get a vapor barrier because of the excess moisture. If you don’t have a vapor barrier in place in these rooms, the moisture will build up and eventually lead to mold and bacteria, not to mention the destruction of the insulation.

Insulating a stone house is an expensive and involved process because it requires building a double-walled house. The walls don’t need to be the same thickness, but they both need to be thick enough to handle any structural demands and meet fire and safety standards. The insulation (usually foam or fiberglass) is then installed between the two stone walls.

Also known as sound-dampening blankets, acoustic blankets reduce echo in a room. They come in different thicknesses and materials, and they can be nailed or glued to walls.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.
