Wall Insulation in Sun Valley NV - filled walls without tearing them open
Cold outside walls or a drafty room that never warms up? We fill the closed wall cavities through small holes and patch them after.
Straight talk on what comes first
I'm usually the one who comes out to look at your walls. If insulating them isn't where your money does the most good yet, I'll tell you that, along with what I'd fix first and what can wait.
In business since 2023
I learned insulation on job sites working beside experienced installers, then started this company in 2023. Before that I ran a small business of my own, so I know what it means to watch every dollar.

Wall insulation for Sun Valley homes
Wall insulation in Sun Valley, NV usually means filling the closed walls of a house that's already built. We drill small holes near the top of each stud cavity, blow in loose cellulose or fiberglass through a hose, and patch the holes, so drafty rooms stop losing heat through the walls.
Most wall calls start with a room that feels drafty or a floor that stays cold along an outside wall, in a house whose walls were closed up with little or nothing inside them. Before anything gets drilled, I want to know how old the house is, what's on the outside and whether you're planning new siding, because those answers decide how we get into the walls and what has to happen first.
The price mostly follows how many square feet of wall need filling, whether we work from inside or outside, and how much patching and prep comes with it, like bathroom tile or old wiring that has to be dealt with first. The schedule turns on the same things, plus any permit and, if you're re-siding, when that job lands. My estimate tells you what I'd do first and puts it in writing.
Wall insulation, from first hole to final patch
Inside or outside, chosen together
We decide with you whether to get into the walls from inside or outside, and it comes down to access and the shape the wall is in. Going in from outside cuts through the drainage plane, the layer behind the siding that sheds water, if your house has one, so that layer has to be patched or replaced, and the patches can show unless new siding or trim goes over them. Going in from inside leaves that layer alone. Either way, we patch the holes when we're done.
Packing each cavity full
Blown-in insulation only works as well as it's packed, because the density of the fiber sets the R-value, which is how well it slows heat. Dense pack, blown in tight, raises that, settles less and cuts the air leaking through the wall. It needs walls that are well sealed and strong enough for the pressure, so I check yours before we choose it. Ask any installer how they make sure every cavity fills completely at the right density, because getting that right takes training.
Siding, foam and the rest of the house
If siding is coming off an empty wood-frame wall anyway, that's the time to insulate, because we can drill the sheathing and blow the cavities full before the new siding covers the holes. Spray foam can fill stud cavities and seal air in one step, but it costs much more than fiber and heat still moves through the studs, so for most walls I'd rather put that money into air sealing services for the gaps. Walls below ground are a different job, covered under basement insulation.
Get a written wall insulation estimate
We reply within one business day, then I come to your home, look at the walls with you and follow up with a written estimate, free and with no obligation. Having your home's age and any siding plans handy helps.

We look at your walls
After you call (775) 447-1132 or send the form, we set a time for me to come out. We walk the rooms with the cold or drafty walls, I tell you right there what I'd do first, and the written estimate follows.
Setting the date and permit
Once you say go, we set the date and take care of any permit the work calls for. If something has to happen before we drill, like old wiring being dealt with or tile coming off, we schedule around it.
Fill, patch and walk through
Our install crew does the work with a lead installer on site, drilling, filling each cavity and patching the holes. They clean up before we walk through the rooms together, so you can see the patches and ask questions.
Wall insulation questions from Sun Valley
How much does wall insulation cost in Sun Valley, NV?
Installing blown-in wall insulation usually costs about $4 to $4.50 per square foot across the US. That's a national figure for the work, not a quote from us, so use it as a rough guide. The estimate I write after looking at your walls gives you your own number.
Do I need a permit to insulate walls in Washoe County?
You need one unless the work is on Washoe County's list of construction and repairs that are exempt from a building permit. We check which office covers your address and take care of the permit when your job calls for one. You can read the county's list of what requires a permit or call its building program at (775) 328-2020.
What should I know before insulating walls in an older house?
Check two things first, lead and wiring. Guidance for houses built before 1980 says owners should be aware of lead safety rules when walls get disturbed, and the national electrical code doesn't allow insulation on or around knob and tube wiring, so that wiring gets dealt with first. We check for old wiring before we drill.
What should I move before the crew insulates my walls?
Mostly furniture and anything hanging on the outside walls, because the crew drills above door headers, above and below windows, and into the cavities behind cabinets on those walls. In a bathroom on an outside wall, some tile may have to come off before we drill, and I'll point out those spots during the estimate.
