"We hired USA Insulation to blow insulation into the ceiling above our garage. Their customer service team was very responsive, had great communication regarding visits, and provided a quote onsite after viewing the job. The job was completed as promised and all the workers were professional and courteous. I also liked the insulating material they used which did not give off fumes like some foam insulation, and was not itchy like fiberglass insulation."

"Our primary bedroom is above the garage and even though we have a newer home, you can feel cold air coming thru the floor. It's the coldest room in the house by far. Ed's team came in and placed foam insulation in the garage ceiling. He gave us $100 off for Angies list discount which was nice. They cleaned up well when done. Now that it's warm out I can't grade the quality of the work until winter again because I won't know till then if its helping with the problem. I will come back and update then. We had been quoted over $6000 by another company to do the work so hopefully this works and comes in far cheaper.

"Project: Seal leaks in attic, install radiant board on a sloped ceiling, and blow in insulation where needed in attic. It was a pleasure dealing with Geoff. He is the ultimate professional - knows how best to insulate an attic, is punctual and honest, is reasonably priced, gives a 10-year guarantee on his work, while in our home he adjusted door sills to ensure there were no gaps under our doors, he is most respectful of ones home and does a fabulous job cleaning up. I can't say enough about Geoff and highly recommend him."

"I felt that AGL did a good job completing the spray open cell insulation. I have noticed that the attic is definately cooler. The winter will be a tell tale sign if the insullation project did the trick to keep the house warmer."
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.
