Wall insulation in Menifee CA - walls filled full and dense, top to bottom
Rooms that run hot in summer and drafty in winter often have hollow walls. We fill them through small holes and pack each cavity tight.

I come out and do the estimate
Nobody gets sent out with a price sheet. I walk the house myself and look at the walls from both sides before I quote anything. Our installers do the work, with me or a lead installer running the job.
Started in 2017 after years in HVAC
I spent years running duct in attics before I started this business in 2017, and I kept finding insulation done wrong. That's why we fix problems first and fill second, so you don't pay twice.
Fully licensed and insured on every job
We're fully licensed and insured, and our work is backed by our satisfaction guarantee. If you want your walls filled right the first time, call (951) 430-8005 or send us the form and I'll come take a look.
Wall insulation in Menifee, done in order
Wall insulation in Menifee means filling the hollow spaces inside your exterior walls, usually by drilling small holes near the top of each cavity and blowing insulation in. It helps when rooms run hot in summer, feel drafty in winter or the power bill keeps climbing.
Most wall calls start with a room that won't stay comfortable, hot all afternoon in summer or drafty on a winter night. When the attic's already been done and that room still won't hold temperature, the exterior walls are often hollow or only partly filled, and you can't see that from inside. I check by looking into the wall at an outlet or a small test hole before I quote anything.
What moves the price is how much wall we're filling, which side we drill from and how much prep an older house needs before we start. The schedule mostly turns on that prep and on whether your job needs a permit. The estimate gives you your price, with the scope in writing so you can see what we're doing and why. In California, this work falls under the state's C-2 insulation contractor license, which covers installing any kind of insulation.
How we handle wall insulation
Every cavity packed full and dense
We fill closed walls through small holes near the top of each cavity instead of tearing out wall. Blown-in insulation, loose fill pushed through a hose, can work into odd-shaped bays and around pipes, wires and blocking, but only when it goes in tight, because a loose cavity settles and leaves an empty band at the top. So we pack each one full and dense. The cellulose trade group says properly installed cellulose can work well for decades, with sound control and fire protection along with it.
Drilling from inside or outside
Which side we drill from matters more than most people expect. Going in from the outside breaks through the wall's drainage plane, the layer that keeps rain from getting behind the outside finish, and it then has to be patched or replaced. Filling from the inside leaves that layer alone, so I usually lean that way and talk it through with you at the estimate. Where we find gaps at outlets and pipes, we close them first with our air sealing services, so the insulation isn't fighting a draft.
Older houses and old wiring first
In an older house, I ask about the build year and the wiring before anything else, because both change how much wall we open. Homes built before 1980 come under lead safety rules, depending on how much of the wall the work disturbs on either side. Knob and tube wiring, the old style run on porcelain knobs, can't have insulation on or around it under the electrical code, so it needs a plan before any wall is filled. Walls below ground are a different job, which we handle as basement insulation.

You call, I come look
Call (951) 430-8005, use the form or email service@menifeeinsulationcompany.com to set a time. I come out, look at the walls inside and out, point out anything that needs fixing first and send you a written scope with the estimate.
We sort out permit and prep
Once you say go, we sort out the permit question with the right office, so you don't have to chase it. Then we cover the floors and clear space along the walls we're drilling.
We fill, patch and walk through
Our installers drill, fill each cavity and close up the holes. If the city issued a permit, its inspections at key stages each have to pass before the final one, and I walk you through the finished work when we're done.
Wall insulation questions in Menifee
What does blown-in wall insulation usually cost?
Installing blown-in wall insulation usually costs about $4 to $4.50 per square foot across the US, and that's a national figure, not a Menifee quote. What you'd pay depends on what I find in your walls, and the estimate gives you your price with the scope in writing.
Can we stay home while our walls are being insulated?
Usually, yes, if your walls are getting blown-in insulation. One contractor writes that people can go about their lives while walls are dense-packed. Spray foam is different, since the whole work area has to be cleared, so you, the kids and the pets would stay out until the re-entry time, when it's safe to come back, has passed.
Who issues building permits for a house in Menifee?
The City of Menifee issues building permits for construction, alterations and repairs through its permit portal, with fees due when the application goes in. Since we work all over this part of Riverside County, we check whether your address is under a city or the county, then ask that office what your job needs and pull the permit when one's required.
Is there help paying for insulation in Riverside County?
There may be, if your household meets the income guidelines. Riverside County residents who qualify may get help through the CAP Weatherization Program, which helps lower-income families lower their energy bills by making their homes more energy efficient. It's worth checking the program's guidelines before you decide how much work to take on.
