Insulation Company in Westwood, CA
Blown in insulation is the most common upgrade we install in Westwood homes, and for good reason. The town’s mill-era houses and cabins, most built between 1910 and 1960, have shallow attics and uninsulated floors over crawlspaces that leak heat straight through the roof and into the frozen ground. At 5,000 feet in the Sierra Nevada, that means furnace runtimes measured in hours, not minutes, and rooms that never quite get warm. We only do insulation, which means we do it better.

Why Westwood Homes Are Different
Westwood sits in Lassen County at roughly 5,000 feet, where winter nights routinely drop below zero and the wind coming off the mountains finds every gap in a building’s envelope. The housing stock here is not like the track-built suburbs down the hill. These are early- to mid-20th-century wood-frame homes and cabins built during the lumber-mill boom, with shallow attics that leave little room for insulation, floors suspended over open crawlspaces, and single-pane windows that frost over on the inside. Most of these houses were built when firewood was cheap and thermal performance was an afterthought.
That changes what we do on nearly every Westwood job. Attic access often comes through a small scuttle hole cut into a closet ceiling, not a pull-down stair. Some crawlspaces are barely 18 inches high, which means crews work on their backs in cold, damp soil. And the knob-and-tube wiring we regularly find buried under old attic insulation in mill-era homes means any insulation upgrade often triggers a wiring inspection before we blow in new material. If you do not know what knob-and-tube is, that is fine. We check for it on every retro we quote in Westwood, because catching it first is the difference between a clean install and a fire hazard that was hidden for decades.
Snow load matters too. A roof that holds three feet of Sierra snow needs an attic that handles moisture correctly. If insulation blocks the eave vents, ice dams form, and water backs up under the shingles. The right material in the right place, installed the right way, keeps the attic cold in winter and dry all year. That is the standard we work to in Westwood, and it is why we do not treat this town like any other mountain ZIP code.
Our Main Westwood Services
The two services Westwood homeowners call about most are attic insulation and spray foam insulation. Both solve different problems in different parts of the house, and the right choice depends on the home itself, not a generic recommendation.
Attic Insulation in Westwood
Attics are the single biggest energy-loss zone in Westwood homes, and most of the attics we see here are under-insulated by 60 to 80 percent. A mill-era home might have three or four inches of settled fiberglass from the 1970s, which is nowhere near enough for sub-zero winter nights. We remove what is there, air-seal the attic floor, and install the right material at the right depth for this climate. Knob-and-tube wiring shows up often enough in Westwood that we check for it on every attic quote before any work begins. Learn more about Attic Insulation in Westwood.
Spray Foam Insulation in Westwood
Spray foam earns its keep in Westwood crawlspaces and rim joists, where cold air pours in under the house and freezes pipes. Closed-cell foam seals and insulates in one pass, and it holds up to the moisture and temperature swings of a high-elevation mountain climate. Open-cell foam works well for attic rooflines in homes where the attic is part of the conditioned space. We carry both Demilec and Icynene products, so the foam we recommend is the one that fits the job, not the one we happen to stock. See Spray Foam Insulation in Westwood for details.

Blown In Insulation in Westwood
Blown in insulation is the workhorse retrofit for Westwood’s older wood-frame homes and cabins. Loose material flows into irregular cavities, settles around odd framing, and covers attic floors evenly at depths that batt insulation simply cannot match in a shallow attic. For a mill-era Westwood house with a cramped scuttle access and settled 1960s insulation, blowing in new material is usually the fastest, cleanest, and most effective fix. The catch is that Westwood’s sub-zero winter nights demand deeper coverage than coastal California code minimums, and knob-and-tube wiring hidden under old insulation must be addressed before any new material goes down. If you have high energy bills and cold floors, Blown In Insulation is where we start the conversation. We only do insulation, which means we do it better, and the right material for your home, not the easiest one for us to install.
Cellulose Insulation
Signs you need it
Rooms directly under the attic feel several degrees colder than the rest of the house, and existing insulation has settled into compacted, ineffective layers.
What it costs in Westwood
Cellulose insulation in Westwood typically runs 11% to 16% less than fiberglass for the same R-value, with attic coverage in the 1,000-square-foot range often priced for this product at standard regional rates.
How we do it
We check for knob-and-tube wiring, route any needed air sealing, then blow the cellulose to the target density and depth with a calibrated machine so coverage is uniform wall to wall.
Blown In Attic Insulation
Signs you need it
Snow melts unevenly off the roof while neighboring homes stay uniformly covered, which usually means heat is escaping through the attic.
What it costs in Westwood
Blown in attic insulation in Westwood is generally the most cost-effective attic upgrade, with the material and labor priced at standard regional figures for this application.
How we do it
We remove or manage the old material, seal the attic floor penetrations, then blow the loose fill to the uniform depth the climate demands, keeping eave vents clear for snow-melt season.
Loose Fill Insulation
Signs you need it
You can see the tops of the ceiling joists through the existing insulation, and ice dams form along the roof edges after every heavy snow.
What it costs in Westwood
Loose fill insulation in Westwood is our most common retrofit approach for older homes, and the total job cost falls in the standard regional range for this method in Lassen County.
How we do it
We probe the existing depth, confirm what is already there, then blow the new material over or in place of it to hit the target R-value without burying vents or wiring.
What Blown In Insulation Costs in Westwood
| Item | Typical range in Westwood |
|---|---|
| Cellulose insulation | 11% – 16% less than fiberglass for equivalent R-value |
| Blown in attic insulation | Most cost-effective attic upgrade method |
| Loose fill insulation | Standard regional rates for Lassen County retrofit work |
Is blown in insulation effective in Westwood’s sub-zero winters?
Yes, when installed to the right depth. Westwood’s climate requires higher R-values than lower-elevation areas, and blown in material achieves that depth in shallow, irregular attic cavities far better than batts. Call us for a calculation specific to your home.
Can you blow insulation over existing attic material in Westwood?
Sometimes. If the old material is dry, settled fiberglass, we can often blow over it. But if it is compressed, pest-damaged, or hiding knob-and-tube wiring, it needs removal or a wiring inspection first. We will tell you which applies before quoting.

Two things push pricing up in Westwood more than anywhere else down the hill. The first is access: scuttle holes in closet ceilings, crawlspaces under 18 inches, and attic framing that was never designed for insulation depth all slow the work and add labor. The second is the knob-and-tube wiring we find in so many mill-era homes; when it is present, a wiring inspection has to happen before we blow in material, and that adds a step, not a surprise charge from us. We quote upfront with the full scope, and the price you approve is the price you pay.

What Westwood Customers Say
"Told me the crawlspace didn't need doing and only the attic did. Half the job, half the money."
— Miguel Flores"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
— Nia Robinson"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Mark Schaefer
