What Attic Insulation Costs in Broward County (2026)
Straight answers with real numbers — per square foot, by job type, and what actually moves the price up or down. No "call for pricing" games.
The Short Answer
Most Broward County attic insulation top-up jobs land between $1,500 and $3,000. Bigger homes, higher target R-values, and jobs that need old insulation removed first cost more. Here's the full breakdown so you can sanity-check any quote you get — including ours.
Blown-In Top-Up
$1–$2 per sq ft
Typical 1,500 sq ft attic: $1,500–$3,000. The most common job in Broward — adding insulation over what you have to reach R-30–R-38.
Removal + Replace
Removal adds $1–$1.50 per sq ft
Full removal-and-replace typically runs $3,000–$5,000. Needed when old insulation is wet, moldy, or rodent-contaminated.
Air Sealing Add-On
Usually a few hundred dollars when done during the insulation job. Sealing gaps around fixtures and pipes before blowing — the step that makes the insulation work at full strength.
What Actually Drives the Price
- Attic size — the single biggest factor. Insulation is priced per square foot of attic floor, so a 2,400 sq ft ranch costs more to insulate than a 2,400 sq ft two-story (which might only have 1,200 sq ft of attic).
- How much insulation you already have — a home with 5" of existing insulation needs less new material to reach R-38 than one that's nearly bare. This is why the inspection matters: you only pay for what your attic actually needs.
- Target R-value — South Florida homes should have R-30 to R-38 (about 10–14 inches of blown-in). Going from R-10 to R-38 costs more material than topping up from R-19.
- Material choice — blown-in fiberglass and cellulose are similarly priced for most Broward jobs; we'll recommend what fits your attic.
- Attic complexity — steep pitches, tight clearances, lots of ductwork or recessed lights add labor time. Simple open attics price at the low end.
- Old insulation condition — if it's dry and clean, we blow right over it (cheaper). If rodents nested in it or a roof leak soaked it, removal comes first.
Is It Worth It? The Payback Math
The EPA estimates that air sealing plus proper insulation saves homeowners about 15% on heating and cooling costs. In South Florida, cooling isn't a season — it's 10–12 months a year, and it's most of your FPL bill.
Run your own numbers: if your summer FPL bills run $350–450/month, cooling is likely $250–350 of that. A 15% cooling saving is roughly $450–$650 per year — which pays back a typical $2,000 top-up in 3–4 years, and everything after that is savings. On top of that, industry data consistently shows attic insulation among the best home improvements for resale value recovery.
And there's the part the math doesn't capture: bedrooms that actually cool down at night, and an AC that isn't running itself to death at 4 PM every day.

Demand a per-square-foot breakdown
A quote should state your attic's square footage, the current insulation level, and the target R-value. "Whole job: $X" with no details makes comparison impossible — that's the point of writing it that way.
Ask what R-value you're getting
Some low quotes reach their price by blowing 4 inches instead of 10. Insist the target R-value is on the quote in writing — R-30 minimum for South Florida, R-38 better.
Ask if air sealing is included
Insulation over leaky gaps is like a blanket with holes. Cheap quotes usually skip this step entirely.
