Insulation Company in Citrus, CA
Blown in insulation is the most common request we field from Citrus homeowners, and the reason is straightforward: most houses in the 91702 ZIP were built between the 1950s and 1970s, when attic insulation was either thin fiberglass batts or, in a surprising number of cases, nothing at all. Those attics now bake under San Gabriel Valley sun that pushes summer temperatures past 100°F, transferring heat straight down into living spaces and forcing air conditioners to run constantly. At Rock Solid Insulation, we solve that with blown in cellulose and fiberglass installed to current Title 24 standards. If your cooling bills feel out of control, call us at (855) 798-0822 for a free estimate.
Why Citrus Homes Are Different
Citrus sits directly against the San Gabriel Mountain foothills, which changes the insulation math compared to coastal Los Angeles or even nearby flatland communities. The valley floor already runs hot in summer, but foothill-edge homes in Citrus catch an extra layer of afternoon sun exposure that drives attic temperatures to extremes. A poorly insulated attic here can reach temperatures well above 140°F on a 100°F day, and that heat load pours down through ceilings all evening. The work we do in Citrus is weighted heavily toward cooling-season performance: higher R-values in the attic plane, air sealing around penetrations, and materials that resist heat transfer rather than simply slowing it.
The housing stock adds another layer. Postwar tract homes in Citrus typically have low-slope or hip roofs with limited attic access, and many still carry original insulation that has settled, compressed, or broken down over 50-plus years of heat cycling. Some older attics contain vermiculite-era material that must be identified and handled carefully before any new insulation goes in. Newer infill homes, by contrast, often meet older energy codes that have since been superseded. Both situations benefit from a fresh look at what is actually in the attic now, not what was put there decades ago.
Brushfire-zone ventilation constraints also apply to foothill-adjacent streets. Attic vents in some Citrus homes must balance heat rejection against ember intrusion risk, which affects how we approach air sealing and vent baffles before blowing in new material. It is a detail general contractors often miss, but it matters here.
Our Main Citrus Services
The two services Citrus homeowners ask us about most are attic insulation and spray foam insulation. Each addresses a different set of problems, and the right choice depends on your home’s construction, roof design, and how you use the space.
Attic Insulation in Citrus
Attic insulation is the first thing we evaluate on any Citrus home with high cooling bills, because the attic is where most heat enters a house in this climate. We inspect what is currently up there, measure settled depth, check for gaps around can lights and duct chases, and then recommend either a top-up or a full removal and replacement. Older Citrus tract homes often need air sealing first; newer homes may only need a depth increase. Either way, the goal is the same: keep attic heat from bleeding into living space. Read the full breakdown on our Attic Insulation in Citrus page.
Spray Foam Insulation in Citrus
Spray foam works differently from blown in insulation, and for certain Citrus homes it is the better tool. Open-cell foam excels at air sealing irregular attic geometries, while closed-cell foam adds structural rigidity and moisture resistance that can matter on low-slope roofs. Foothill-adjacent homes with unvented attic designs or rooms over garages are common candidates. Because we carry both Icynene and Demilec systems, we can match the foam chemistry to the specific roof and ventilation situation rather than forcing one product onto every job. Details are on our Spray Foam Insulation in Citrus page.

Blown In Insulation in Citrus
Blown in insulation is the workhorse fix for Citrus attics, especially in those 1950s-70s tract homes where the existing material has settled to a fraction of its original depth. Loose fill cellulose or fiberglass gets blown into every corner, around trusses, and over irregular surfaces in a way batt insulation simply cannot match. That full coverage is what stops the superheated attic air from pressing down into bedrooms and hallways all afternoon and evening. For most Citrus homes, it is the fastest, most cost-effective way to cut cooling costs. You can read more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the ceiling joists, or your upstairs rooms stay hot well after sunset even with the AC running.
What it costs in Citrus
Blown in cellulose in Citrus typically runs $1.20 – $2.25 per square foot depending on depth, access, and whether old material must be removed first.
How we do it
We air seal penetrations, install vent baffles where needed, then blow GreenFiber cellulose to the target R-value using calibrated equipment that ensures consistent density across the entire attic floor.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic are noticeably warmer than the rest of the house, or you can see bare drywall and exposed joists when you look into the attic.
What it costs in Citrus
Full blown in attic insulation in Citrus generally lands between $1,800 and $3,400 depending on square footage, target R-value, and access difficulty.
How we do it
We remove any compromised old material, seal air leaks at top plates and penetrations, mark target depth with attic rulers, and blow loose fill uniformly to the specified R-value.
What Blown In Insulation Costs in Citrus
| Item | Typical range in Citrus |
|---|---|
| Blown in cellulose (attic, R-38) | $1.20 – $2.25 per sq ft |
| Blown in fiberglass (attic, R-38) | $1.10 – $2.00 per sq ft |
| Full attic removal and re-blow | $1,800 – $3,400 |
Is blown in insulation worth it in Citrus?
Yes. In a climate where attic heat is the dominant energy load, bringing settled insulation up to R-38 or higher cuts cooling costs measurably and evens out room temperatures. We see the biggest payoff in pre-1980s tract homes. Call (855) 798-0822 for a site assessment.
How long does blown in insulation last in Citrus?
Cellulose and fiberglass both hold their R-value for decades, but high attic heat and occasional Santa Ana winds can accelerate settling in poorly installed jobs. Properly dense-packed, blown in insulation in this climate should perform for 20 to 30 years. We check depth on every estimate.
Brands We Service in Citrus
We carry Owens Corning, Johns Manville, Knauf, and Rockwool products for Citrus jobs, with fiberglass and mineral wool batts stocked locally for quick turnaround. Our brands page lists the full lineup and what each material does best.

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."
— Dev Patel"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Sami Mansour"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
