"They had good communication, prompt and easy scheduling, showed up on time and did a great job. I've let my neighbors know that I would recommend North Florida Insulation to update their home's insulation, also. I am hopeful the results will now begin showing up in our electric bills. Thanks!"

"Mr Herring was professional and on time to give me a quote. He was exceptional to point out a malfunction at the A/C duct at my home. He recommended I fix the issue before insulation installation. After several quotes, Mr Herring has the best pricing and was hired a week later. He arrived on time and provided the service with a smile and was pleasant to talk to. The team cleaned up after the installation and I went on with my day. I would like to recommend Precision Fiberglass Insulation."

"I had innovation spray foam come out and do some blown insulation in the attic. It is a family business run by a bunch of brothers all were very nice. Pete was the man I initially talked to he made sure I got what I was looking for and his twin brother Betuel came by and knocked out the work in 1 day! Very happy with the work!"
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.
