Wall insulation in Evansville IN - warmer rooms without redoing your walls
Cold, drafty rooms along the outside walls every winter? We fill the walls the way your house is built, so rooms hold heat.
Can you insulate the walls of a house that's already built?
Most existing houses in Evansville can get wall insulation without tearing anything out. Usually that means blowing loose insulation through a hose into the hollow spaces inside your outside walls. It can also go on the outside before new siding, or on the inside under new sheetrock, which is mostly how unfinished basement walls get done. Done right, the rooms along those walls stop feeling cold and drafty.
Most of these calls come from older houses around Evansville where the outside walls feel cold to the touch, the room over the garage never warms up, or the power bill jumps every winter. The price mostly turns on how much wall there is, what the walls are made of and how we have to get into them. The schedule turns on the same things, plus whether new siding is coming, because that changes the best way in. Cold walls often come with a thin attic too, so I'll tell you if attic insulation would do more for you. You get your own number once I've looked at the house. If the job needs a permit, we check with the building office that covers your address and handle it before we start.
How our wall insulation work goes
I start by finding out what your walls are, because a wood-frame wall with open cavities gets a different plan than a brick wall or a block wall. Where there are cavities, we check that the inside walls can take the pressure of packed insulation and aren't hiding water damage, since a wall stuffed with insulation over a wet spot is just a nicer-looking wet spot. Then we close up the leaks, fill each cavity all the way from top to bottom, patch our holes and clean up before we go. If new siding is in your plans, tell me at the start, because that can change how we get into the wall.
Insulation slows heat, but it does very little against air pushing through gaps around outlets, windows and the spot where the house sits on its foundation. That's why we usually pair this job with air sealing services, which means closing those gaps before the insulation goes in. If the walls bothering you are below ground, that's basement insulation, and it's a different job with its own plan.
Why Evansville homeowners call A&B Evansville Insulation Services for their walls
The owner writes your estimate
I come out to look at your walls and write the estimate myself, and our own crew does the work with me on most jobs. The person who promised you something is usually standing there when it gets done.
Licensed for Evansville building work
Evansville and Vanderburgh County require licensed contractors for work on buildings, and getting that license means passing a written exam, an experience check and showing proof of insurance. We're fully licensed and insured, so you're not taking a chance on whoever had a free week.
Leaks sealed before walls get filled
I started this business in 2023 after years on another outfit's crew and some time away, and coming back I saw how often the leaks got skipped and the insulation just went in on top. We seal first, because insulation can't do its job while a draft keeps blowing right past it.
Straight answers about your walls
If your walls have a moisture problem or a roof leak above them, I'll tell you to fix that first instead of selling you insulation that won't help. Every job is backed by our satisfaction guarantee.
On wall work, the order of the steps matters more than the material. Call (812) 205-2872 or send us your project with your wall type, any siding plans and a rough square footage of wall, and I'll take it from there.

Wall insulation, start to finish
Questions before you book wall insulation
What is the best way to insulate existing walls in Evansville?
For most wood-frame houses, blowing insulation into the wall cavities is the best way, because it's the cheapest method and the least disruptive, with no new siding or inside refinishing needed. It only works if the walls have cavities, and some brick and cement walls don't, so I look at yours before suggesting anything.
How much does blown-in wall insulation cost?
Across the US, installing blown-in wall insulation usually costs about $4 to $4.50 per square foot, and that's a national figure, not an Evansville quote. Your number moves with how much wall there is, whether we can work from outside or have to go in from inside, and any leaks or damage that need fixing first. Have a rough square footage of wall in mind when you call, and the estimate gives you your own price.
Should I add insulation when I replace my siding?
Usually yes, because adding continuous insulation on the outside while the old siding is off costs only a little more than the siding by itself. The energy savings often take 5 to 10 years to pay it back, but the house feels more comfortable and quieter right away. The catch is that rigid foam board isn't recommended over wood-frame walls with little insulation inside, because it traps water vapor in the wall, so we look at what's in there before we pick what goes on the outside.
Who issues building permits in Evansville?
The city's Building Commission issues building permits in Evansville, and you need one before work on any structure or its parts. Its list names siding and drywall but not wall insulation, so we ask the office that covers your address before we start, and when the job calls for a permit, we handle it. If you're doing the work yourself on the house you live in, you or your immediate family can get a permit without a contractor license.
Do I have to leave my house while my walls get insulated?
Usually not, because most blown-in wall work happens outside, where the crew takes off some siding and drills through the board layer behind it to fill each cavity. That keeps the mess out of your living space. If the walls have to be filled from inside, installer guidance calls for covering the floor and closing off the work area so the dust stays put.
How do I get help paying for wall insulation in Indiana?
Indiana's Weatherization Program can serve households with incomes up to 200% of the federal poverty level, or households that qualify for the Energy Assistance Program. The house also has to be safe to weatherize, and the program decides that, so check with them before you plan around it.
Other work that pairs with wall insulation
- Air sealing services
If your rooms still feel drafty with the walls filled, the air is probably getting in around outlets, windows and the foundation, and sealing those gaps is the fix.
- Basement insulation
Cold floors upstairs often start with bare basement walls, and those get insulated from the inside on their own plan.
