Insulation Company in West Covina, CA
Blown in insulation is the most common fix we perform in West Covina, where 1960s-era attics with settled fiberglass batts let conditioned air escape straight through the ceiling. Even Air Insulation has served West Covina since 2018, and the calls we get follow a pattern: rooms that won’t hold temperature, upstairs bedrooms ten degrees warmer than downstairs, and cooling bills that spike every July. We’re a multi-method insulation specialist, which means we start with what the house actually needs, not what’s easiest to install. Call (855) 362-0195 for a free estimate and we’ll tell you straight what’s going on up there.
Why West Covina Homes Are Different
West Covina’s housing stock does not age evenly. The 91790 and 91791 ZIP codes hold thousands of 1950s and 60s ranch-style tract homes built when R-11 attic insulation was standard practice, if insulation went in at all. Six decades later, that fiberglass has settled, compressed, and in many cases been trampled flat by tradespeople running cable and ductwork. The result is what we see constantly in attics across the 91791 ZIP: original batts that measure an inch and a half thick, leaving bare patches of drywall directly under a broiling roof deck. Meanwhile, the 91792 and 91793 ZIP codes skew toward 1980s and 90s two-story developments where the insulation was often adequate for the era but no longer meets what utility programs and modern comfort expectations ask for.
The San Gabriel Valley climate adds pressure. Summer days over 95°F are not exceptional here, and attic temperatures in uninsulated or under-insulated homes regularly climb past 140°F. That heat radiates down through ceilings for hours after sunset, keeping air conditioners running long into the evening. Winters are mild but not negligible, and the same attics that overheat in August leak warmth in January. The right insulation strategy for a West Covina home almost always starts with the attic because that’s where the physics of heat gain and heat loss concentrate first.
Our Main West Covina Services
Most West Covina homeowners call us about one of two things: an attic that is not doing its job, or a specific room or wall cavity that needs a more targeted approach. Both services have their own dedicated pages for this area.
Attic Insulation in West Covina
In older West Covina ranch homes, attic insulation is typically the highest-return energy upgrade available. We see attics where the original insulation has degraded to the point of being decorative rather than functional, and the fix is often more straightforward than homeowners expect. The work involves assessing existing material, air-sealing the attic floor where practical, and bringing the space to current recommended R-values for the San Gabriel Valley’s hot-summer climate. For details on how we approach attics in West Covina specifically, including what different areas of the house need, see our Attic Insulation in West Covina page.
Spray Foam Insulation in West Covina
Spray foam is not always the right answer, but West Covina homes built on hillsides or with complicated rooflines often have cavities and knee walls that batts simply cannot treat. With access to both Icynene and Demilec product lines, we can offer open-cell and closed-cell formulations matched to the moisture and structural requirements of the specific space. The 1980s and 90s homes in the 91792 ZIP, for example, frequently have bonus rooms over garages with uninsulated floor cavities that respond well to foam.

Blown In Insulation in West Covina
Blown in insulation is the most practical retrofit option for most West Covina attics, particularly in 1960s tract homes where the original fiberglass has compressed to a fraction of its intended depth. Blowing new material over the top, or removing the degraded batts entirely and starting fresh, restores even coverage across the whole attic floor and eliminates the hot and cold spots that drive West Covina homeowners to pick up the phone. Even Air Insulation carries Blown In Insulation products from GreenFiber and Johns Manville, so the material choice is driven by what your attic actually needs. On a Ranch-style home in the 91791 ZIP, that usually means a dense layer of cellulose that fills every corner where batts left gaps.
Cellulose Insulation
Signs you need it
Your attic has old fiberglass batts that look flat, dirty, or uneven, and your upstairs rooms struggle to hold temperature in summer.
What it costs in West Covina
Blown-in cellulose for a typical West Covina attic runs $1,500 to $3,500 depending on square footage and whether old material needs removal first.
How we do it
We air-seal the obvious bypasses, then blow GreenFiber cellulose to an even depth that hits the R-value target for the San Gabriel Valley climate.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic are noticeably hotter than the rest of the house in summer and colder in winter, and your cooling bills keep climbing year over year.
What it costs in West Covina
Full blown-in attic insulation on a 1,200 to 1,800 square foot West Covina home typically lands between $1,800 and $4,200.
How we do it
We remove or top the existing material, seal the attic floor penetrations, and blow the new insulation to a consistent depth across the entire attic.
Loose Fill Insulation
Signs you need it
You can see bare drywall patches in your attic, or the existing insulation is so shallow you can count the ceiling joists from the access hatch.
What it costs in West Covina
Loose fill insulation jobs in West Covina range from $1,200 to $4,000 based on attic area, access difficulty, and the depth required.
How we do it
We run a hose from the truck to the attic, blow the material into every corner and around every truss, and level it to the specified depth.
What Blown In Insulation Costs in West Covina
| Item | Typical range in West Covina |
|---|---|
| Blown-in cellulose attic (1,200 – 1,800 sq ft) | $1,500 – $3,500 |
| Full blown-in attic insulation | $1,800 – $4,200 |
| Loose fill insulation | $1,200 – $4,000 |
How long does blown in insulation last in West Covina?
Cellulose blown in insulation lasts 20 to 30 years in West Covina attics before it settles enough to matter. Fiberglass loose fill settles less, but still loses effectiveness if disturbed by roof work or pest activity.
Can you blow insulation over existing insulation in my West Covina attic?
Yes, if the existing material is dry and not compressed, we can often blow new insulation directly over it. We check for moisture and rodent damage first because covering those problems makes them worse. Call (855) 362-0195 for an inspection.

What West Covina 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."
— Emily Gallagher"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Luis Garcia"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Andres Vargas
