Wall insulation in Hollister CA - warmer rooms without tearing out your walls
Rooms that run cold along the outside walls usually have empty walls. We fill them through small holes, so the room holds its heat.
I look at your walls myself
I come out to look at the job myself, so whoever prices your walls has actually seen them. If a wall isn't worth filling, I'll tell you that instead of selling it to you.
Finding the problems first, since 2017
I was crawling attics on a summer crew before I could drive myself to the job. We're best known for the dull part, finding gaps and problems before any insulation goes in, because I don't want anything unsafe buried in your walls.
Fully licensed and insured
You can ask to see proof of our insurance before we drill the first hole. Satisfaction guaranteed on every job. When you're ready, call (831) 245-4007 or use the form to set up a visit.
Wall insulation for Hollister homes
Wall insulation fills the empty spaces inside your outside walls, so less heat gets through them. In a house that's already built, we drill small holes and fill each wall space, which helps anyone with drafty rooms or a high power bill from walls that were never insulated.
Usually it's a drafty room that won't stay comfortable, along the outside walls of a house built with little or nothing in them. The price moves with how much wall there is, what's on the outside and what has to be fixed before we fill. The schedule turns on those same repairs and on any permit, which I check for your address. Your own number comes from the estimate, after I've seen the walls.
Two choices shape the job. Foam is usually the most expensive way to fill a wall that's already closed up, so for most houses I'd point you to blown-in insulation, loose fill blown through a hose. The other is whether we work from inside or out, which the questions below cover. House age matters too, and if yours was built before 1978, the EPA's guide to lead-safe renovation is worth a read before work starts.
Wall insulation and the sealing around it
Small holes, from inside when we can
I'd rather fill walls from inside when we can, because the siding stays whole and a small hole in drywall or plaster is easy to patch. We drill near the top of each wall space between the studs and blow insulation in until it's full. Inside work makes dust, so we cover the floor under each wall and clean up as we go, and it's fair to ask any crew how they'll keep dust from spreading through your house.
Packing walls tight so they stay full
Dense-packing blows the insulation in tight, under pressure, instead of letting it fall loosely into the wall. Packed that hard, it slows heat better, settles less over the years and lets less air move through the wall. It needs walls that are well sealed and strong enough to take the push, so whether yours qualify is one of the first things I check. If a wall isn't a good candidate, I'll say so and tell you what it would take to get it there.
Sealing the leaks around the walls
Filling a wall doesn't stop air sneaking in around outlets, window trim and where the wall meets the floor, so those gaps are worth closing with our air sealing services while we're there. Cold floors are often the next complaint once the walls are done, and over a basement, basement insulation is usually the fix. On the visit I'll tell you which of these is worth doing now and which can wait, so you're not paying for work that won't change much.

(831) 245-4007How a wall insulation job goes
You call, I come look
You call or send the form, and we get back to you. I come out myself to look at the walls, and you get a written estimate that lists what needs fixing first and what we'd do about it.
Permits sorted before we start
We sort out any permit with the right office before work starts. Where your address falls to the county, the San Benito County Building Division reviews the application and plans first, so we schedule once that's done.
Crew fills, I check it
Our crew drills, fills and patches, then I check the work before we call it done. We walk through the rooms with you so you can see the patches and ask anything while we're still there.
Wall insulation questions from Hollister homeowners
Should wall insulation go in from inside or outside my house?
From inside, when we can get to the walls, because drilling from outside breaks the drainage plane, if your wall has one. That's the layer behind your siding that sheds water, and it then needs patching or replacing. From outside, small pieces of siding may come off, and patches can show unless new siding or trim covers them.
How much does blown-in wall insulation cost in Hollister?
Across the US, installing blown-in wall insulation usually costs about $4 to $4.50 per square foot. That's what the market charges nationally, not our price, and repairs, old wiring and outside patching all change what a given house costs. I'll look at your walls on site and put your own number in writing.
Who is allowed to install wall insulation in California?
A licensed contractor, and the license that covers insulation in California is the C-2 Insulation and Acoustical license from the state licensing board, for installing any insulation used for temperature or sound control. The state lets someone unlicensed take jobs up to $1,000, but only when the work needs no permit and that person employs no one.
What happens to my walls before you fill them with insulation?
We check them for moisture and damage first, and any moisture problem gets found and fixed before we fill, because packing a damp wall buries it. Cracked plaster gets repaired, since dense-packing can make weak spots worse. If your house has knob and tube, an early kind of wiring, one guide reads the electrical code as barring insulation around it.
