Insulation Company in Westwood, CA
Blown in insulation solves the two problems Westwood homeowners deal with every single winter: heat escaping through old, settled attic material and cold air finding its way through every gap in a 1960s-era frame wall. At East Los Angeles Insulation Co, we’ve been insulating homes at 5,000 feet since 2018, and we know that loose fill done right means the difference between a $400 heating bill and a $200 one. That’s why we carry GreenFiber cellulose and CertainTeed fiberglass, not whatever one brand happens to be on the truck. Call (866) 566-0304 when you’re ready to talk about your attic, your walls, or that crawlspace you’ve been avoiding.
Why Westwood Homes Are Different
Westwood sits in Lassen County at roughly 5,000 feet, which means the insulation math here is different from the coast or the valley. Older mountain homes and cabins, most built between the 1950s and 1980s, were framed for a different era. Builders stuffed in whatever was cheap, often thin fiberglass batts that have since slumped, been chewed through by rodents, or soaked through by ice dams. Single-pane windows and uninsulated crawlspaces are common. The ridge above town holds snow well into May, and when it melts, it finds the weak spots.
Wildfire hardening adds another layer here. Westwood’s position in a high-elevation Sierra timber town means exterior foam and mineral wool details have to meet WUI ignition-zone rules. That’s not a suggestion. When we blow insulation into exterior walls or add material under a reroof, we’re thinking about the code requirements that come with living in a wildfire-prone forest. Then there’s the cold side of the equation: freezing nights start early and hang around late. A home here needs insulation that handles both extremes, not one or the other.
Our Main Westwood Services
Westwood homeowners usually call us about two things: attic insulation that’s failed or never been adequate, and spray foam for the hard-to-reach gaps that make old cabins so drafty. Here’s what each job looks like in town.
Attic Insulation in Westwood
Attics in Westwood take a beating. Snow loads sit on the roof for months, and when warm interior air leaks up, it melts snow at the deck, refreezes at the eaves, and soaks the insulation below. We routinely find wet or compacted batts in cabins where nobody has looked in years. The fix starts with ventilation, then air sealing, then fresh coverage matched to the home’s age and construction. Attic Insulation in Westwood gets into how we handle the snow and ice problem specifically.
Spray Foam Insulation in Westwood
Closed-cell foam matters in Westwood because rim joists and crawlspace walls leak heat all winter long. Open-cell works in interior walls where you want sound control and air sealing. We install Icynene and Demilec, two brands with field performance records in cold climates. In an older cabin with a vented crawlspace, foam can transform the floor temperature. Spray Foam Insulation in Westwood covers the full scope.
Blown In Insulation in Westwood
Blown in insulation is the most practical retrofit for Westwood’s older cabins. Most 1950s-to-1980s wood frame homes here were built with batts that have settled to half their original R-value, and blowing in loose fill over or around them restores performance without tearing out walls. We install GreenFiber cellulose, which is made from recycled paper and packs tightly to resist airflow, and CertainTeed fiberglass, which holds its loft for decades. Both go in fast, usually in a single morning, so you’re not living through a long construction project in the middle of snow season. For the full picture on how we approach this material, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation looks flat and dusty rather than fluffy, or your upstairs rooms are colder than the main floor by 5 degrees or more.
What it costs in Westwood
Blown cellulose in a Westwood attic typically runs $1,500 to $3,800 depending on square footage and how much old material needs to come out first.
How we do it
We air seal the major bypasses with foam, then blow GreenFiber cellulose to the target R-value, checking depth markers as we go and keeping soffit vents clear.
Blown In Attic Insulation
Signs you need it
Snow melts unevenly on your roof, with bare patches over living space while snow lingers at the eaves, a classic ice-damming signal that attic heat is escaping.
What it costs in Westwood
Most Westwood attic blow-ins run $1,700 to $4,200 when we’re removing compacted batts, air sealing, and adding ventilation before the new material goes in.
How we do it
We inspect the deck for moisture, address any ice-dam damage, install baffles at the eaves for airflow, then blow to the depth required for your target R-value.
Blown In Fiberglass Insulation
Signs you need it
Your existing fiberglass batts are compressed under boxes, split at the seams, or hosting rodents, all of which kill the material’s ability to slow heat flow.
What it costs in Westwood
Blown fiberglass over existing batts in Westwood typically lands between $1,500 and $3,600, with the lower end for simple top-offs and the upper end for full removal.
How we do it
We remove any contaminated material, seal gaps with spray foam, then blow CertainTeed fiberglass to an even depth, fluffing as we go so it holds its stated R-value.
Loose Fill Insulation
Signs you need it
Your attic has thin or missing coverage in the corners and around the perimeter, where hand-placed batts often leave gaps that add up to real heat loss.
What it costs in Westwood
Loose fill in a Westwood attic runs $1,600 to $3,900 on average, depending on whether we’re filling bare joist bays or topping up material that’s still sound.
How we do it
We run a hose into the attic and blow loose material at controlled density, using a leveling tool to hit consistent depth across the whole floor, including the edges.
What Blown In Insulation Costs in Westwood
| Item | Typical range in Westwood |

| Blown cellulose attic insulation | $1,500 – $3,800 |
| Blown fiberglass attic insulation | $1,500 – $3,600 |

How long does blown in insulation last in Westwood’s climate?
Cellulose and fiberglass loose fill hold their R-value for 20 to 30 years here if mice stay out and the roof doesn’t leak. Wet snow years are the big variable, so we check for moisture before adding anything new. Call (866) 566-0304 for an attic inspection – it’s free.
Should I remove old insulation before blowing in new material in Westwood?
If the existing material is wet from ice damming or full of rodent droppings, yes, it has to come out. If it’s just settled but dry and clean, we can blow right over it and save you the removal cost.

What pushes prices up in Westwood is the age of the house. If we’re pulling out 40-year-old batts that are soaked through from ice damming or full of squirrel nests, that’s labor and disposal cost. If the attic is tall and open, the blow-in goes fast and the price stays at the lower end. Every quote here is fixed before we start, no surprise add-ons at the end.

FAQs About Insulation Company in Westwood
Most Westwood jobs happen within one to three days of your call. Attic inspections and estimates are free and can often be scheduled same-day during spring and fall. In deep winter, snow on the access roads can push us a day.
Most insulation retrofits in Westwood don’t require a permit, but if your job involves wildfire-hardening assembly changes under WUI rules, Lassen County may want a plan review. We’ll tell you upfront if your project crosses that line.
Yes, and that’s the standard here. Exterior foam and mineral wool details under WUI ignition-zone rules have to work alongside deep-cold insulation. We plan for both at the same time instead of doing one and hoping the other holds up.

What Westwood Customers Say
"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
- Jason Walsh"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
- Rosa Martinez"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
