"On really hot summer days my attic temperature can exceed 110°+ with no problem. But that heat was being transferred to the bedrooms below and just about making the HVAC in the attic ineffectual. Home Advisor recommended Dixie's Insulation. I spoke to Mr. Magadon, and got a more than reasonable quote. Dixie's crew showed up early and within three hours were done. The thermostat temperature would normally read anywhere from 83° to 100° But after Dixieâ s Insulation, LLC. finished, I get readings in the 70° range. Dixie's got my wife and daughter to complain about it being cold. I would recommend Dixie's Insulation to anyone."

"These guys took time from their busy schedule came to my residence on Easter Sunday to give me a price on repairing insulation mess left by previous contractor. They arrived next day and completed the insulation work and did an excellent job at an excellent price. My thanks to Sagittarius air seal thanks again, Michael Duffy."

"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"I'll start off by saying that Right Way originally installed an interior french drain for us in 2003. Soon after we had our basement finished. From that time on we never had to worry about a flooded basement. It was a big job and they were awesome! When our sump pump started making noises last week, I called in the morning and Al came out that day. He fixed our issue then had another installer came back out the following day to install a new backup system. I would highly recommended these guys!

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.
