Blown-in insulation in Evansville IN - an attic that holds heat and still breathes
Hot upstairs in summer, drafty in winter, and a power bill that keeps climbing? We seal the gaps, then blow in an even layer.

Does my attic need blown-in insulation?
In Evansville, blown-in insulation is loose cellulose or fiberglass blown through a hose across your attic floor to fill a thin or empty attic, so less heat slips out through the ceiling in winter and less pours down on you in summer.
If the upstairs bakes all summer, the room over the garage never warms up, or the power bill looks like a car payment, the attic is the first place I look. I own A&B Evansville Insulation Services, and we work in Evansville and across the area, including Henderson, Mount Vernon, Boonville, Princeton and other cities nearby. The price mostly comes down to the size of the attic, how many inches are already up there, how many gaps need sealing first, and whether the old stuff has to come out. The schedule turns on what has to be fixed before we start, like a roof leak or old wiring. Your own number comes from the estimate, after I've been up there.
How we do blown-in insulation, in order
I go up first and look at what's there, how deep it is, and whether anything is wet, chewed or lying on old wiring. Then our crew does the air sealing, closing the gaps around can lights, pipes, wires and the attic hatch, because insulation laid over a draft just gets blown through. Next we put baffles in at the eaves, short chutes that hold an air path open from the soffit vents, so the attic can still breathe and the new insulation stays where it belongs instead of spilling into the eaves. We keep it off recessed lights that aren't rated to be buried, since those run hot. Then we blow it in at an even depth all the way out to the top of the walls, packed dense enough that it won't settle into thin spots, because a lot of attics I climb into are deep in the middle and bare at the edges, which is exactly backward.
Sometimes the attic isn't ready for more. If the old layer is soaked or full of droppings, we pull it out with insulation removal first, because fresh material on top just hides the mess. Foam costs more and seals while it insulates, but sealing the gaps and topping up with loose fill usually wins, unless your ductwork runs through the attic, and then spray foam is worth a look. When the cold floors and drafts go past the attic, we look at the rest of the house as part of our home insulation work.
Why Evansville homeowners call us for blown-in insulation
The owner climbs into your attic
I come out, go up in your attic and write the estimate myself, and I'm on most jobs with our own crew. The person who saw the problem is the one standing up there when it gets fixed.
Sealing first, since 2023
I learned this trade on another outfit's crew, spent some years away, and came back in 2023 to start this business. What jumped out was how often the leaks got skipped and the insulation got piled on top, so we seal first and blow second.
Straight answers on older homes
Most of our calls come from older homes in and around Evansville, where an attic can hide a roof leak or wiring that's older than the homeowner. If that's what's up there, I'll tell you to fix it first rather than sell you insulation that won't help.
Covered before anyone climbs up
We're fully licensed and insured, and I'm glad to show you the paperwork at the estimate. Our work is backed by our satisfaction guarantee.
On this job the order matters more than the depth. Call (812) 205-2872 or send us a note, and tell us your home's age, how you get into the attic, and any recessed lights, old wiring or vermiculite you've spotted up there.

What a good attic looks like
What people ask about blown-in insulation
How much does blown-in insulation cost in Evansville?
Attic insulation in Evansville usually costs about $1,400 to $4,800 per job, and that's the going rate around here, not our quote. A small attic that only needs topping up tends to sit toward the low end, and one that needs heavy sealing or the old material pulled out sits higher.
What happens before blown-in insulation goes in?
The attic gets checked first for roof leaks, moisture, and pest or structural damage, and you get a list of what needs fixing so you can plan and budget for it before the insulation. Insulation only goes over knob and tube wiring, the old wires strung on porcelain knobs, once that wiring has been replaced or properly boxed. If the old insulation is vermiculite, a pebbly gray-brown fill that may contain asbestos, the work stops until that's dealt with. Then come the sealing and baffles described above.
Do I need a permit for blown-in insulation in Evansville?
The Building Commission oversees the codes for any home alteration or repair in Vanderburgh County, so that's the office to ask. Each city and county around here has its own building office, so we check with the one that covers your address before work starts, and when the job calls for a permit, we handle it. If you're doing the work on the house you live in, the commission may issue the permit to you or your immediate family without the license a contractor would otherwise need. Where a local license applies, contractors pass a written exam and an experience check and show proof of insurance, bond and workers' comp.
How long does cellulose insulation last?
Properly installed cellulose can keep working well for decades. What usually cuts that short is a roof leak, critters, or an install so loose it settles and leaves holes, which is why the prep and the packing matter more than the brand on the bag.
How do I know if my attic needs more insulation?
Go up with a flashlight, stay on the framing, and if you can see the tops of the ceiling joists, the wood the ceiling hangs from, it's thin. Many older homes started with little or nothing up there, and a hot upstairs, drafty rooms or a cold room over the garage are the usual signs. Tell us how many inches you see when you call.
Do I have to leave the house while you blow in insulation?
Usually not. The blowing happens up in the attic with a hose run in from outside, so the dust mostly stays up there, and you just keep kids and pets away from the hatch and the hose until we're done. Re-entry time, the wait before you can come back inside, is a spray foam thing, not a blown-in one.
Work that often goes with it
- Insulation removal
When what's in the attic now is wet, chewed or full of droppings, it has to go before anything new can do its job.
- Home insulation
If the drafts and cold floors don't stop at the ceiling, a look at the whole house finds where the rest of the heat is going.
