What attic insulation costs in Brevard County
Four things set the number, and only one of them is square footage. Here is what a Brevard attic job is priced on, and the $220 rebate that comes off the top.

Why nobody can price this over the phone
Any contractor who quotes you a firm number before seeing your attic is guessing at four things at once, and three of them are invisible from the driveway.
Attic square footage is the easy one. The other three are what actually move the price: the R-value you are starting from, the R-value you need to reach, and whether the material already up there has to come out before anything new goes in.
That last one is the difference between a routine job and a two-stage one. Insulation that is wet, compacted, or contaminated by rodents cannot be topped over. It has to be removed first, and removal is its own line.
The R-value your Brevard attic is supposed to hit
Brevard County is Climate Zone 2A in the Florida Building Code, Energy Conservation, which is the warm-humid designation the state applies to most of peninsular Florida.
For Zone 2, ENERGY STAR recommends R49 for an attic with no insulation, and R38 where there is already three to four inches up there. Those figures come from the 2021 International Energy Conservation Code, Table R402.1.3.
This is the single biggest driver of your number. Going from R19 to R38 is a different job from going from R30 to R38, in the same attic, on the same day.
What comes back off the number
Two things reduce the real cost, and both are documented rather than estimated.
Florida Power & Light pays a $220 rebate per installation on ceiling insulation. It is not applied to every home: FPL requires an active residential account, whole-house central electric air conditioning and heating, and a verified existing ceiling R-value below R-8. The work also has to be done by a contractor enrolled in FPL's program. We cover exactly who qualifies in the rebate guide.
Then there is the bill itself. ENERGY STAR estimates that air sealing and insulating attics, crawl space floors and rim joists saves an average of 15% on heating and cooling costs, or about 11% of total energy costs. In a Brevard house running the AC eight months a year, cooling is most of the bill.
Why we do not publish a price list
We measure your attic and write the number in front of you, on site, for free. No deposit, no obligation, no coming back with a revised figure.
We could publish a per-square-foot rate. It would be wrong for most houses, because the three variables above swamp square footage, and a number that is wrong on your house is worse than no number at all.
What we will tell you on the phone is the honest version: what we need to see, and how long it takes to see it.
