Services in South Florida
Illustration Blown-in attic insulation
Loose fill blown across the attic floor. The usual fix for a thin layer in a dry, open attic.
Illustration Spray foam attic insulation
Foam on the roof deck that seals the attic. It costs more and fits homes with ducts in the attic.
Attic insulation removal
Takes out wet, soiled or old insulation so new insulation starts on a clean floor.
Radiant barrier
Reflective foil that turns roof heat back. It helps most where attic insulation is thin.
How to size up your attic
- Take the Attic Heat Score. Answer a few questions about your home. You get a score and the reasons behind it. It is a starting point, and the Attic Heat Score page shows what it is based on.
- Know what a good check covers. A good attic check records the type of insulation, its depth in inches and photos of problem spots. Use that list when you talk to any installer.
- Ask for a written price. Ask for the scope, the product, the installed R-value and the price in writing. Nothing should start until you say yes.
- Compare and decide. Use the cost guide to compare quotes. If your attic already has enough insulation, you may not need work.
- See the finished job. Ask for photos and a depth reading after the work, so you can see the result.
Cities we cover in South Florida
Which service fits your attic?
Start with what you see and feel. Many homes need one of these, and some need a mix.
- Hot upstairs, thin or patchy insulation, open attic floor. Start with blown-in insulation.
- Ducts or an air handler in the attic, or you want a sealed attic. Price spray foam.
- Wet, stained or soiled insulation. Start with attic insulation removal, then add new insulation.
- Some insulation already, and the roof bakes the attic. Ask about a radiant barrier.
- Not sure. Take the Attic Heat Score.
Why a measured attic comes first
The right job depends on what is in your attic today: the type, the depth, the moisture and the roof above it. Home age is a clue, not proof. We found no survey of real attic R-values by year built, so we do not guess.
Start by finding out what you have. Then ask for a written price, so you can decide with the numbers in front of you.
Rules, rebates and prices
Each service page explains the Florida energy code, permits and the FPL rebate rules that touch that job, with the source next to every figure.
For prices side by side, see the cost guide. Ranges there come from named national guides, not South Florida quotes.

Questions people ask
Which attic service should I start with?
For most homes with a thin layer and an open floor, start with blown-in insulation. If you are unsure, run the Attic Heat Score and find your depth in inches.
Who handles asbestos or vermiculite insulation?
A licensed asbestos professional. If you think your attic has vermiculite or asbestos, stop and do not disturb it. That is licensed abatement work, and none of these services cover it. See the attic insulation removal page.
Can I combine services?
Yes. Removal followed by new insulation is common. Some homes add a radiant barrier to a thin layer. Ask for one written scope that covers the whole job.
