Why blown-in

Your attic is where the heat gets in

In South Florida, the sun bakes your roof all day and that heat pushes down into your home. A thick, even layer of blown-in insulation slows that heat before it reaches your ceilings, so your AC can keep up.

Loose-fill insulation is blown in with a hose, so it settles around wiring, pipes and framing where batts leave gaps. Whether you need a top-off or a full new layer, we'll bring your attic up to the right depth.

  • Quick install, usually in a few hours
  • Fills gaps around pipes, wires and framing
  • Lower cooling costs and a quieter home
  • Great value for older or under-insulated attics

FAQ

Common questions

How much does blown-in insulation cost?

Typically about $1 to $3 per square foot, or roughly $1,000 to $3,000 for a 1,000 sq ft attic, depending on the material, depth and whether old insulation needs to come out. Read our blown-in insulation cost guide for the full breakdown, or get an exact price with a free inspection.

Can you add insulation on top of what I have?

Often, yes. If your existing insulation is dry and in good shape, we can top it off. If it's damaged or contaminated, we'll recommend removing it first.

How long does it take?

Most attic jobs are finished in a few hours to a day.

Will it make a mess in my house?

No. We work from the attic, protect your home, and clean up when we're done.
