"⭐⭐⭐⭐⭐ Outstanding Blown-In Insulation Installation I had an excellent experience with National Energy Solutions for a blown-in insulation installation in my garage. From start to finish, the process was professional, efficient, and stress-free. The team arrived on time, clearly explained the work they were doing, and completed the installation with great attention to detail. The blown-in insulation was installed evenly and thoroughly, and they made sure everything was clean and orderly before leaving. You can immediately tell they take pride in their work. What stood out most was their customer service. They were respectful, knowledgeable, and patient in answering my questions. The improvement in temperature control in my garage was noticeable right away, and I feel confident the insulation will make a long-term difference in comfort and energy efficiency. I highly recommend National Energy Solutions to anyone looking for quality insulation work done right the first time. Professional"

"We recently purchased a home that had an attic that had been infested by mice. Grant and his team did an excellent job of removing the soiled insulation, sterilizing the area, and adding new formaldehyde-free insulation. What particularly impressed me was that Grant noticed that we had a bad situation with an exhaust fan that was exhausting into the attic and came up with an excellent fix on the spot. We paid a fair price and the work was done in a timely manner. I would highly recommend Atlanta's Best Insulation."

"The crew did a great job. They were very courteous and hard-working. I had always been reluctant to get my vents cleaned because I feared that there would be dust everywhere afterwards. That was not the case at all. It really was a beautiful job and they even cleaned my dryer vent! I have noticed that my power bills have gone down some because of the more efficient airflow that I am getting. I can’t say enough good about these folks."

FAQs for insulation service projects in Dunwoody, GA

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.
