Insulation Company in Citrus, CA
Blown in insulation is the workhorse upgrade for Citrus homes, and for good reason. Most houses here were built between the 1940s and 1970s, when attic insulation was an afterthought – a thin layer of fiberglass that’s now compressed, dusty, and barely doing its job. Combine that with San Gabriel Valley summers that push attic temperatures past 140°F, and you get upstairs bedrooms that never cool down and AC units that run nonstop from June through October. Laguna Hills Insulation has served Citrus since 2014, and we’ll tell you straight: the fix is usually more attic insulation, properly installed, not a bigger AC unit.

Why Citrus Homes Are Different
Citrus sits in the San Gabriel Valley foothills, which means two things for insulation work: intense, dry summer sun and older housing stock that was never built for it. Most of the homes here are post-war and mid-century tract builds – single story, low-slope or shallow-pitch roofs, and attics with clearance so tight you sometimes have to crawl on your stomach to reach the far corners. That changes the job. Blowing in insulation in a 1960s Citrus attic isn’t like working in the wide open attics of newer Glendora or Covina subdivisions. The access hatches are smaller, the framing is tighter, and the original insulation – if it hasn’t been replaced – is usually a half-inch of matted fiberglass that’s been baking for fifty years.
What matters most in Citrus is attic heat gain. Warm air rises, and in July and August your attic becomes an oven that radiates heat down into the living space all night. Proper attic insulation – combined with good ventilation – is the single most effective upgrade for cutting AC bills here. Wall insulation matters less in this climate than attic insulation, simply because heat comes from above, not through the walls.

Our Main Citrus Services
Citrus homeowners contact us most often about two insulation jobs: attic retrofits and spray foam applications. Here’s what each involves locally.
Attic Insulation in Citrus
In Citrus, attic insulation work is almost always a retrofit, not new construction. Houses here have low-clearance attics where original insulation was installed decades ago and has settled, compressed, or been disturbed by rodents and roof work. We assess what’s up there, remove or top up what’s failing, and install new material at the R-value that makes sense for the San Gabriel Valley climate. Many Citrus jobs include radiant barrier work because the sun is the real enemy here. See the full breakdown on our Attic Insulation in Citrus page.

Spray Foam Insulation in Citrus
Spray foam in Citrus is a different conversation than attic insulation. It’s for homeowners dealing with specific problems: rooms that stay hot even after attic insulation was improved, air leaks around can lights and top plates, or crawlspace humidity. Closed-cell foam from Icynene or Demilec creates an air barrier and a thermal barrier in a single application, which matters when your attic gets as hot as Citrus attics do. It’s a more involved installation, but sometimes it’s the right call. Details and pricing are on our Spray Foam Insulation in Citrus page.

Blown In Insulation in Citrus
Blown in insulation is the most common job we perform in Citrus because it’s the most practical fix for what these homes actually need. Most Citrus attics have either no insulation left that’s worth keeping or a thin, settled layer of original fiberglass that does almost nothing against San Gabriel Valley heat. Blown In Insulation means loose fill material – fiberglass, cellulose, or a mix – blown into the attic cavity to create a deep, even thermal layer. It’s faster and more complete than batts, and it gets into the tight corners and shallow eaves that define so many Citrus attics.
For Citrus specifically, the material choice matters. Cellulose (recycled paper treated with fire retardant) is denser and blocks airflow better than fiberglass, which helps in attics that get scorching hot. Fiberglass is lighter and less dusty. We’ll tell you which fits your attic – even if it’s not the most expensive option.
Cellulose Insulation
Signs you need it
Your attic insulation has settled to below the top of the ceiling joists, or your upstairs rooms won’t cool below 80°F on summer afternoons.
What it costs in Citrus
Blown in cellulose for a typical Citrus attic runs $1,800 to $3,400 depending on square footage and existing insulation removal.
How we do it
We seal air leaks around top plates and penetrations, then blow cellulose to a consistent depth that meets your target R-value, leveling as we go.
Blown In Attic Insulation
Signs you need it
Your energy bills spike every summer, and the attic feels like a furnace even after sunset, radiating heat into bedrooms below.
What it costs in Citrus
Blown in attic insulation in Citrus typically costs $1,500 to $3,200 for a standard tract home, with low-clearance attics adding labor time.
How we do it
We remove or top up failing insulation, install baffles to keep soffit vents clear, and blow new material to an even, code-exceeding depth.
Blown In Fiberglass Insulation
Signs you need it
The existing fiberglass batts are matted, mouse-damaged, or barely an inch thick, and you want a lightweight replacement.
What it costs in Citrus
Loose fill fiberglass for a Citrus attic runs $1,600 to $3,000, slightly less than cellulose on average.
How we do it
We blow fiberglass at a controlled density to the specified R-value, working around ductwork and recessed fixtures without compressing the material.
Loose Fill Insulation
Signs you need it
Your attic has bare spots, scattered old batts, or uneven coverage from a previous partial install that left gaps.
What it costs in Citrus
Loose fill attic insulation across Citrus runs $1,500 to $3,400, with disposal of old material adding $400 to $800 when needed.
How we do it
We assess the existing layer, decide whether to remove or top up, and blow loose fill material to a uniform depth across the entire attic floor.
