"I love this company! Garrett came to my home and assessed how efficient our current insulation, etc was. He was very informative and friendly — explained what we needed and how they could help. At the time, I decided to hold off and he never pushed the sale. When I was ready, he was quick to accommodate my schedule. His team: Angel, Luis, Tommy and TJ were great! They arrived early, were professional, courteous, kind, very helpful with my questions and were above and beyond to help fix things that I wasn’t even aware of. They also were more than happy to help with small problems that I had no idea how to fix. They worked quickly and cleaned up afterwards. You could tell they cared about their work which makes me feel confident that the job was done right. They were also fun to have around — my Great Dane loved them too! Garrett and Dave checked in with me during and afterwards to make sure things were going well and if I had any questions. I highly recommend Eagle Shield."

"When Insulation Alliance came, they were very professional. They laid down plastic everywhere in the hallway and the bedroom. They cleaned out the whole attic. They took out the old insulation and put in the new Insulation which was R 44. They cleaned up everything and everything was clean when they left. They also sanitized the attic. You will not be disappointed that you hired."

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.
