Insulation Company in Citrus, CA
Blown in insulation is the work we do most in Citrus, and for good reason: the mid-century ranches and tract homes around 91702 were built when attic insulation was an afterthought, and now those vented attics under low-pitch roofs are losing cooled air through settled, degraded material. We’re Hometown Insulation Co, an insulation-only company, and we’ve served Citrus since 2013. If your summer AC bill feels like it’s running away from you, call (877) 265-9918 for a straight diagnosis.
Why Citrus Homes Are Different
Citrus sits in the hot, dry San Gabriel Valley just below the Angeles National Forest foothills. That location shapes every insulation job we take here. Summers routinely push above 90°F, and the intense sun bakes low-slope and low-pitch composition roofs all afternoon. The real insulation battle in Citrus is attic radiant heat and cooling load, not winter cold. That means the highest-return work in this city is almost always in the attic, not the walls, and often includes a radiant barrier alongside a blown-in top-off.
The housing stock tells the same story. Citrus is dominated by single-story tract and ranch homes from the 1950s through the 1970s. Many still have their original thin attic insulation, now settled, dusty, and compressed to a fraction of its rated R-value. We regularly measure attics in Citrus that have barely R-10 coverage. On those older tracts below the foothills, the fix is rarely a wall retrofit. It’s a dense blown-in upgrade across the attic floor, and in many cases a radiant barrier under the roof deck to cut the heat that’s radiating down into the living space.
One more thing about Citrus: the dry climate works in your favor. Moisture and vapor-barrier concerns that complicate jobs in coastal cities are lighter here, which means cleaner installations and fewer surprises when we open the attic access.
Our Main Citrus Services
The two calls we get most from Citrus homeowners are for attic insulation and spray foam. Both address the same core problem, uneven room temperatures and high cooling bills, but they solve it differently depending on the home.
Attic Insulation in Citrus
In Citrus, attic insulation typically means either a blown-in top-off over old settled material or a full removal and fresh install when the existing layer has been compromised. We’ll assess the depth, check for gaps around can lights and plumbing penetrations, and recommend the right R-value for a San Gabriel Valley attic. For the full breakdown of how we handle this in Citrus, see our Attic Insulation in Citrus page.
Spray Foam Insulation in Citrus
Spray foam makes sense in Citrus when homeowners want to seal the attic against superheated air intrusion, especially in homes where the attic houses ductwork or HVAC equipment. We install open-cell and closed-cell systems from Icynene and Demilec, products built for performance envelopes, not entry-level coverage. For specifics on closed-cell versus open-cell in Citrus attics, see our Spray Foam Insulation in Citrus page.

Blown In Insulation in Citrus
Blown in insulation in Citrus usually means topping off an attic in a 1950s-to-1970s ranch home where the original fiberglass has settled to a thin, dusty layer under the low-pitch roof. With summer attic temperatures climbing well past 120°F, the goal is dense, even coverage across the attic floor so cooled air stops escaping upward and radiant heat stops pressing down. We carry several material options, including GreenFiber cellulose and fiberglass from Owens Corning and Johns Manville, so we can match the material to your home rather than installing whatever’s on the truck. Learn more about the service itself on our Blown In Insulation hub.
Cellulose Insulation
Signs you need it
Your attic insulation sits below the top of the joists, looks dusty and compacted, or you can see the attic floor through it.
What it costs in Citrus
Blown-in cellulose for a typical Citrus attic runs about $1.00 to $2.80 per square foot installed, depending on depth and whether we’re topping off or starting fresh.
How we do it
We air-seal bypasses, run a hose to the attic, and blow GreenFiber cellulose to a consistent depth across the full attic floor, checking coverage with depth markers as we go.
Blown In Attic Insulation
Signs you need it
Rooms near the ceiling feel noticeably warmer than the rest of the house, or your AC runs for hours on hot afternoons without hitting the thermostat setting.
What it costs in Citrus
Attic blow-in work in Citrus typically runs $1.00 to $3.75 per square foot installed; smaller attics land near the top of that range on a per-square-foot basis because of setup time.
How we do it
We set up the blower at the truck, run the hose through the attic access or a gable vent, and blow fiberglass or cellulose evenly across the attic floor to the agreed R-value.
Blown In Fiberglass Insulation
Signs you need it
You want the same thermal performance as cellulose but prefer fiberglass, or your contractor specified fiberglass for a particular attic configuration.
What it costs in Citrus
Blown-in fiberglass in Citrus runs $0.80 to $2.60 per square foot installed, making it a strong value when you’re topping off an attic that already has some coverage.
How we do it
We use Owens Corning or Johns Manville fiberglass, blown through specialized equipment that fluffs the material and spreads it evenly without the settling problems older installations had.
Loose Fill Insulation
Signs you need it
You have an irregular attic floor with lots of gaps, odd framing, or penetrations that make batts impractical.
What it costs in Citrus
Loose fill in Citrus ranges from $0.80 to $3.75 per square foot installed, varying with the material you choose, the depth required, and the accessibility of the attic.
How we do it
We fill gaps and odd cavities with loose material, blowing it into place so it conforms to the attic’s shape and leaves no uninsulated pockets.
What Blown In Insulation Costs in Citrus
| Item | Typical range in Citrus |
|---|---|
| Blown-in fiberglass | $0.80 – $2.60 per sq ft installed |
| Blown-in cellulose | $1.00 – $2.80 per sq ft installed |
| Attic blow-in (all materials) | $1.00 – $3.75 per sq ft installed |
Is blown in insulation worth it in Citrus?
Yes. With Citrus attic temperatures routinely above 120°F in summer, a top-off from R-10 to R-38 or R-49 cuts the heat load on your AC and shows up directly in lower cooling bills. We quote the job up front, so call us for exact numbers.
How long does blown in insulation last in Citrus?
Fiberglass can last decades but settles over time, while GreenFiber cellulose holds its depth better and resists settling. In Citrus’s dry climate, both materials hold up well in a sealed attic. Call (877) 265-9918 for an attic assessment.
Brands We Service in Citrus
We install products from Owens Corning, Johns Manville, GreenFiber, and Demilec in Citrus attics, keeping the common parts and materials stocked locally for fast turnaround. Most of what we need for a typical Citrus job is on the truck or at our nearby yard, so start dates don’t slip. See our brands for the full lineup and what each material does best.

FAQs About Insulation Company in Citrus
We can usually schedule a Citrus attic assessment within a day or two. The city is compact and our crews are in the San Gabriel Valley every week. Installation dates depend on scope, but most Citrus blow-in jobs go from quote to done within 1 to 2 weeks.
For most attic top-offs and blown-in insulation in Citrus, no permit is required. If your project involves air sealing, duct sealing, or spray foam in certain configurations, local building codes may require one. We’ll tell you during the quote if your job needs anything beyond the standard install.
Can you match the insulation in my existing Citrus home if only part of the attic needs work?
Yes. We carry fiberglass, cellulose, and spray foam in a range of R-values, so we can match what’s already in your attic rather than tearing everything out. In Citrus’s older ranches, we often blend GreenFiber cellulose over older fiberglass to hit the target depth without a full removal. Call (877) 265-9918 and we’ll take a look.

What Citrus Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Daniel Lawson"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
— Steven Kim"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."
