Attic Insulation FAQ

Most residential attic insulation jobs in Central and Northern Florida fall between roughly $1,500 and $3,500, depending on attic square footage, the depth needed to hit R-30 to R-38, and whether old material has to be removed first. We give a real price over the phone — no obligation, no site visit required for most quotes.

No. The vast majority of our quotes are completed over the phone. We'll ask about your home's square footage, attic access, and what's currently up there. That's usually enough to give you an accurate number on the spot.

Radiant barrier is a reflective foil installed to the underside of your roof rafters — it's like putting your house in the shade — it reflects 97% of radiant heat back out of the attic. Blown-in fiberglass sits on top of your ceiling joists and slows conductive heat transfer between the attic and your living space. Attic insulation keeps the hot and cold in the house. These products serve two totally different functions: radiant barrier reflects heat, keeping the attic cooler, and blown insulation insulates to keep the A/C in the house. Radiant barrier is so important because it plays a vital role in keeping the attic itself much cooler. They solve different problems, and Florida homes benefit most when you install both.

Most residential blown-in fiberglass jobs take 2-4 hours, while radiant barrier takes 4-6 hours start to finish. Larger homes or combined installs can run into a second day. Insulation removal adds a few hours depending on volume and contamination.

Yes — Florida homeowners commonly see noticeable summer A/C savings within the first billing cycle after a proper radiant barrier and R-38 blown-in install. The exact percentage depends on your starting insulation, A/C efficiency, and how cool you keep your home, but the savings are real and consistent.

Only when it makes sense. If your existing insulation is contaminated by rodents, water-damaged, or just badly degraded, removal is the only honest path forward. If it's clean and structurally sound, we can often add new material directly on top to reach the right R-value.
