Wall insulation in Bozeman MT - warm rooms without tearing out your walls
Cold outside walls and a room that won't warm up? We fill the hollow walls and plug the holes so they look like before.
Can you insulate the walls of a house that's already built?
For a house people already live in, wall insulation in Bozeman, MT usually means blowing loose insulation into the hollow spaces between your studs through holes we drill and then plug, so the room warms up and the walls look the same as before.
Most wall calls I get start with one room that never warms up, or an outside wall that feels cold to the hand in January. A lot of the time those walls were built hollow and nobody ever filled them, and the attic has been taking the blame for years.
The price moves with how much wall you have, what's already inside it, what kind of siding you have and how easy it is to work around, and anything I find that has to be fixed before it gets covered. The schedule turns on the same things, plus whether a permit is needed, and your written estimate lays out what we'd do, in what order, and what it costs.
- Fits wood stud walls with empty hollow spaces, since some brick and cement walls have nothing to fill.
- Most of the work happens outside, so your rooms and inside walls are left alone.
- We get in by lifting part of the siding or drilling through it, then plug every hole.

I check what's in your walls

(406) 414-0411Questions about wall insulation in Bozeman
These are the questions I hear most from someone standing in a cold room wondering what's behind the drywall. If yours isn't here, ask me when I come out.
Can my walls be insulated without tearing them open?
Yes, most hollow walls can be insulated without tearing them open. Blowing insulation in is the most economical and least disruptive way to do it, because you don't need new drywall or new siding.
How much does blown-in wall insulation cost in Bozeman?
Across the US, installing blown-in wall insulation usually costs about $3.90 to $4.60 per square foot of wall. That's a national figure, not our price, and yours comes on the written estimate after I've looked at your wall area, what's inside and your siding.
What if my walls already have some insulation in them?
Adding more to walls that already hold insulation is often too hard to do or not worth the money. Empty wood stud walls are the ones that pay off, so if yours are already filled, I'll say so and point you to where your money does more good.
What causes moisture problems when insulating walls?
One known cause is putting stiff foam boards over wood walls that are poorly insulated inside, because the boards hold water vapor in and it can build up inside the wall. The usual advice is against it, and I'd rather fill a hollow wall than wrap over it.
Who is allowed to do insulation work in Montana?
All construction contractors in Montana now have to be licensed with the Montana Department of Labor & Industry, so ask any installer about theirs before they start. We're fully licensed and insured.
How do I decide which walls to insulate first?
Start with the walls above ground, which is the usual advice for Montana homes. Below-grade walls come after, and your estimate will say which rooms I'd do first and why.
