Blown-In Insulation in Bradenton, FL

Blown-in insulation is loose cellulose or fiberglass that a machine blows through a hose across the attic floor. It settles around trusses, wires and pipes without the gaps that batts leave, and it is one of the least expensive ways to raise an attic to R-38 or more. For many Bradenton homes with an open, walkable attic, blown-in over a well-sealed ceiling gives you most of the comfort gain at a fraction of the cost of foam.

Cellulose or fiberglass

Cellulose is made mostly from recycled paper treated with fire retardant. It is dense, fills gaps well and resists air movement better than loose fiberglass. Loose-fill fiberglass is lighter, does not absorb water as readily and does not settle as much. Both work. We recommend one or the other based on your attic, any existing material and your preference, and we install to a stated depth, not just a number of bags.

What we do before blowing

Air sealing comes first. Blowing insulation over open gaps leaves the hot attic air leaking into the house. We seal around the top plates, lights, fans and the hatch, and we install baffles at the eaves so the new insulation does not block the soffit vents. Florida attics depend on that intake air to carry heat out.

Local prices

Homeyou's Bradenton cost page lists an average blown-in job of $1,164 to $1,499, with a wider range of $606 to $2,526. National guides from HomeGuide and Fixr run higher on larger attics. The true figure depends on attic size, the depth you want and how much sealing is needed.

Walls

Dense-pack cellulose can be blown into closed wood-frame walls through small holes. Most Bradenton homes have concrete block exterior walls with furring strips, so this is more common for frame additions, older wood houses and interior walls between living space and the garage.
