Insulation Company in Covina, CA
Blown in insulation is the workhorse retrofit for Covina’s older homes, and it’s what most homeowners here call us about first. The 1940s-1960s ranch and tract houses that make up most of 91722 and 91723 were built when attic insulation was an afterthought, often just a thin layer of the original material or nothing at all. On a July afternoon, those attics routinely hit 140°F or higher, and that heat doesn’t stay up there. It pushes straight down into the living space. Call us at (833) 390-3099 if your upstairs rooms bake while the thermostat says 78.
Why Covina Homes Are Different
Covina sits in the San Gabriel Valley foothills, and the insulation math here is inverted compared to what homes closer to the coast need. Summer heat regularly pushes past 100°F, and the Santa Ana winds that rake the 91722 and 91724 edges dry everything out and drive dust through every leak in the envelope. We’re not chasing cold-climate R-value the way a contractor in the mountains would. We’re solving for attic heat gain and radiant-heat rejection, because that’s what actually moves the needle on comfort and summer electric bills in Covina.
The housing stock makes this even more specific. The core of Covina, the 91722 and 91723 ZIP codes, is dominated by post-WWII single-story tract and ranch homes. Many still have their original attic insulation, and plenty have effectively none. We regularly open attics in Covina that have a single gable vent and no soffit venting at all. That’s not just an insulation problem; it’s a ventilation problem that has to be solved in the same pass, or the new insulation settles early and traps heat. The 91724 foothill side is different, with 1980s-2000s construction and more varied attic layouts, but even those homes often fall short of today’s Title 24 energy standards.
Our Main Covina Services
Most Covina homeowners reach out to us about two specific jobs, and both get their own dedicated pages because they’re big enough topics to deserve them.
Attic Insulation in Covina
Attic work in Covina almost always means dealing with what’s already up there before adding anything new. The older homes in 91723 rarely have enough ventilation to keep a properly insulated attic healthy, so the job usually includes air sealing, vent correction, and then the insulation itself. We match the material to the attic, not the other way around, and in Covina that often means blown-in fiberglass or cellulose over air-sealed floors. For the full breakdown of how we handle Covina attics, see Attic Insulation in Covina.
Spray Foam Insulation in Covina
Spray foam earns its keep in Covina on the homes where air leakage is the real enemy. The dry foothill air and Santa Ana winds push dust and hot air through every crack in an older home’s framing, and open-cell or closed-cell foam seals those gaps while insulating in one step. We install Icynene and Demilec spray foam, two brands most general insulation contractors in the area don’t carry. Read the full Covina breakdown at Spray Foam Insulation in Covina.

Blown In Insulation in Covina
Blown in insulation is the most common retrofit we do in Covina because it’s the fastest way to fix an under-insulated attic without tearing out ceilings or rebuilding roof lines. The older homes in 91722 and 91723 were built when R-value standards barely existed, so a 1950s ranch with an original thin layer of insulation is losing an enormous amount of conditioned air straight through the attic floor. Blown-in material gets into the corners, around the odd framing, and over the existing insulation where batts would leave gaps. We recommend Blown In Insulation for most Covina attics because it fills irregular joist bays and old, settled spaces better than anything else short of spray foam.
Cellulose Insulation
Signs you need it
Your attic has less than 6 inches of loose material, or the existing insulation has settled and left bare patches around the eaves.
What it costs in Covina
Cellulose insulation in Covina typically runs $1.10 to $1.70 per square foot installed, depending on depth and access.
How we do it
We air-seal the attic floor first, then blow GreenFiber or similar recycled-content cellulose to the target depth using a two-person hose-and-machine setup.
Loose Fill Insulation
Signs you need it
Your attic has old, compressed fiberglass or mineral wool that’s no longer holding its loft, or there are bare spots you can see from the hatch.
What it costs in Covina
Loose fill insulation in Covina generally costs $0.98 to $1.55 per square foot installed, with the final number tied to the depth needed.
How we do it
We run a blower hose into the attic, install depth markers, and fill evenly across the entire floor, including over the top plate and around obstacles.
What Blown In Insulation Costs in Covina
| Item | Typical range in Covina |
|---|---|
| Attic insulation removal | $1.10 – $2.40 per sq ft |
| Blown in attic insulation (new work) | $1.75 – $3.30 per sq ft |
| Blown in attic insulation (over existing) | $1.75 – $3.30 per sq ft |
Is blown in insulation worth it in Covina’s heat?
Yes. In Covina’s 95-105°F summers, a properly insulated attic keeps the living space 10-15°F cooler without touching the thermostat. The payback on summer cooling alone usually covers the job within a few years.
Can you blow insulation over old material in a Covina attic?
Usually yes, but only after we check the old material for rodent damage, moisture, and settling. Blowing new material over compromised old insulation traps problems. Call (833) 390-3099 and we’ll assess yours honestly.
Brands We Service in Covina
We stock and install across a focused set of manufacturers rather than pushing a single product. In Covina, that means jobs finished with Rockwool mineral wool batts, CertainTeed blown-in fiberglass, Icynene open-cell foam, and Demilec closed-cell foam, depending on the house. Parts and materials are staged locally, so most Covina jobs start within a few days of the estimate. See our brands for the full lineup.

In Covina, the biggest price driver is attic access and condition. Older 1950s homes with low-pitch roofs, narrow hatches, and existing knob-and-tube wiring take longer and push labor costs up. Whatever the number, we quote it upfront before any work starts.

Most retrofit insulation jobs in Covina don’t require a city permit, but there are exceptions for roofline spray foam and some whole-home remodels. We’ll tell you upfront if your job falls into that category and handle the paperwork if it does.
Yes, and it’s common in the 1940s-1950s homes in 91722 and 91723. We inspect the attic first and adjust the material and method so insulation never covers live wiring in a way that creates a fire risk. Safety comes before scope on every job.

What Covina Customers Say
"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."
— Carmen Reyes"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
