Insulation Company in West Covina, CA
Blown in insulation is the fastest way to fix the thin, settled attic insulation we find in most West Covina homes built between 1950 and 1975. Homeward Insulation Co has served West Covina since 2012, and the pattern is consistent: original fiberglass batts compressed to half their install depth, attic hatches leaking air, and summer cooling bills that climb every time the San Gabriel Valley heat spikes past 100°F. If your upstairs rooms feel ten degrees hotter than downstairs, call us at (855) 473-6516 for a free estimate.
Why West Covina Homes Are Different
West Covina sits in the eastern San Gabriel Valley, where summer temperatures routinely exceed 95°F and occasionally top 105°F, while winter nights can dip into the 40s. That swing means attics bake during the day and homes lose heat quickly after sunset. The housing stock makes it worse. Most of West Covina’s single-story and two-story tract homes went up in the 1950s and 60s during the postwar boom, and builders met the insulation codes of that era, not this one. We regularly find R-11 fiberglass batts in attics where R-38 to R-60 is what actually works here.
There’s another West Covina-specific detail we look for on every job: knob-and-tube wiring. Some of the older neighborhoods still have it, and loose-fill or spray foam cannot be installed over or around it safely. We identify it before any work starts and flag it for a qualified electrician first. The attic access hatch is another recurring problem. In many West Covina tract homes, it’s a simple plywood scuttle in a hallway closet with zero insulation on the back. That hatch can leak as much air as a small open window, and we seal it as part of most attic jobs.
Our Main West Covina Services
Attic insulation and spray foam are the two calls we get most often from West Covina homeowners, and they address different problems. Here’s what each one looks like in this city.
Attic Insulation in West Covina
For most West Covina homes, attic insulation is the single highest-impact efficiency fix available. The original fiberglass in these 1950s and 60s tract homes has settled, compressed, and in many cases been disturbed by decades of wiring and plumbing work. We remove what’s failing, air-seal the attic floor, and install fresh material rated for the San Gabriel Valley’s heat. One thing to note: finished attics are common in West Covina, and those need a different approach than open attics. See the full scope at Attic Insulation in West Covina.
Spray Foam Insulation in West Covina
Spray foam solves a problem West Covina’s older homes share: air movement through gaps and cracks that fiberglass can’t stop. When we spray open-cell foam in a West Covina attic, it seals the air leaks while insulating, which matters when outdoor temps swing from 45°F nights to 105°F afternoons. We work with both Icynene and Demilec formulations, so open-cell and closed-cell are both on the table. The right choice depends on your roofline, venting, and whether the attic is finished.

Blown In Insulation in West Covina
Blown in insulation is the most practical upgrade for West Covina’s tract homes because it fills the entire attic cavity evenly, including the odd corners and shallow spots where batts never fit right. We blow loose-fill fiberglass or cellulose across existing attic floors, bringing R-values up without tearing out drywall. West Covina homeowners choose this route when their original attic fiberglass has settled to less than half its install depth and they want the job done in a single day. Learn more about the method at Blown In Insulation. We pull from GreenFiber for cellulose and CertainTeed for fiberglass, matching the material to your ceiling type and budget.
Blown In Attic Insulation
Signs you need it
Your upstairs rooms won’t hold temperature, your attic insulation looks thin or settled, or your summer SCE bills keep climbing while the AC runs nonstop.
What it costs in West Covina
Blown in attic insulation in West Covina typically runs $1.50 to $3.50 per square foot installed, depending on target R-value and material.
How we do it
We air-seal the attic floor, set depth markers, blow loose-fill to the specified R-value, and finish by sealing the attic hatch and checking airflow around soffits.
Blown In Cellulose Insulation
Signs you need it
You want recycled material with higher density than fiberglass, or your existing attic insulation has settled so much that you can see the ceiling joists from above.
What it costs in West Covina
Blown in cellulose in West Covina runs $1.25 to $2.50 per square foot installed, with the material itself accounting for roughly $0.30 to $0.65 per square foot.
How we do it
We load GreenFiber cellulose into the hopper, blow it to the target depth using a hose run from the truck, and level it for consistent R-value across the attic floor.
Loose Fill Insulation
Signs you need it
Your attic has irregular joist spacing, low-clearance areas, or existing batts that have degraded but are still in place and just need a topping layer.
What it costs in West Covina
Loose fill insulation in West Covina runs $1.00 to $3.00 per square foot for the material, with labor typically adding another $40 to $75 per hour.
How we do it
We blow loose-fill material over the existing insulation where it’s clean and dry, or remove the old layer first if it’s compacted, rodent-damaged, or damp.

Does blown in insulation settle over time in West Covina?
Quality blown in insulation installed at the correct density settles minimally, usually losing less than 5% of its depth over 20 years. Most West Covina homes with severe settling are dealing with 60-year-old original material. Call (855) 473-6516 to have us measure what’s in your attic.

Most West Covina attics take one day, including air-sealing and hatch work. Larger two-story homes with multiple attic zones may take a second morning. We schedule around your calendar and clean up before we leave. Call (855) 473-6516 for a specific timeline.
