Insulation Company in Citrus, CA
Blown in insulation is the most common request we get from Citrus homeowners, and for good reason. The 1950s and 1960s tract homes across the 91702 ZIP have original attic insulation that’s often R-11 or less, which means cooling costs spike every summer when attic temperatures climb past 150°F. Fountain Valley Insulation matches the material to the job rather than selling one product to every house. Call (833) 390-3099 for a free estimate.
Why Citrus Homes Are Different
Citrus sits in a genuine heat pocket of the San Gabriel Valley. Summer afternoons regularly push past 95°F, and 100°F+ days aren’t unusual. Attic temperatures in these conditions routinely exceed 150°F, which is brutal on insulation that was installed when these homes were built. Most post-war tract homes in Citrus use wood-frame construction on slab foundations, and the original attic insulation was usually R-11 fiberglass batts at best. That’s not enough for today’s cooling loads.
What makes Citrus unique is the combination of that heat with older roof systems. Many homes near Citrus College and along the older streets off Foothill Blvd still have original 2×4 rafters and minimal attic venting. When you add insulation to a poorly vented attic, you can actually trap heat and accelerate shingle failure. We look at ventilation first because the housing stock here demands it. Homes in Citrus aren’t just under-insulated; they’re under-vented, and the two problems have to be solved together. That’s why our approach for this area always starts with understanding how the attic breathes, not just how much material we can blow in.
Our Main Citrus Services
Most Citrus homeowners call us about one of two things: upgrading attic insulation in an older home, or sealing the building envelope with spray foam. Both address the cooling-dominant climate here, but they work differently.
Attic Insulation in Citrus
Attic insulation is the highest-impact upgrade for most Citrus homes because heat gain through the roof drives summer cooling costs. In a 1960s tract home with original R-11 batts, bringing attic insulation up to current R-30 or R-38 standards can change how the whole house feels by late afternoon. The key for Citrus attics is pairing the new insulation with proper ventilation so you don’t turn the attic into a heat trap. We work with blown-in fiberglass, blown-in cellulose, and mineral wool options depending on the attic layout and existing conditions. Learn more about our Attic Insulation in Citrus approach.
Spray Foam Insulation in Citrus
Spray foam earns its keep in Citrus when homeowners want air sealing along with insulation. The older wood-frame construction in this area has plenty of gaps around top plates, plumbing penetrations, and recessed light housings that let conditioned air escape. Closed-cell spray foam seals those gaps while adding R-value, which is valuable when summer temperatures climb and cooling loads dominate. We install spray foam through Icynene and Demilec, two brands most general insulation contractors don’t carry. See how Spray Foam Insulation in Citrus works for open attics, hard-to-reach ceiling cavities, and full envelope upgrades.

Blown In Insulation in Citrus
Blown in insulation is the most practical upgrade for most Citrus attics because it fills the irregular cavities and shallow rafter bays common in 1950s and 1960s tract homes. In Citrus, where attic temperatures regularly exceed 150°F, upgrading from original R-11 fiberglass to a full R-38 blown-in layer typically cuts cooling costs more than any other single improvement. We work with both fiberglass and cellulose blown-in products, and the right choice depends on your attic’s venting, your roof condition, and whether you want recycled-content material. This is the heart of our Blown In Insulation service.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, settled, or barely covers the tops of the ceiling joists.
What it costs in Citrus
Blown-in cellulose insulation in Citrus typically costs $1.00 to $1.70 per square foot installed, depending on depth and prep work.
How we do it
We air-seal the major penetrations first, then blow GreenFiber or similar cellulose to the target R-value, working around existing wiring and fixtures.
Blown In Attic Insulation
Signs you need it
Upstairs rooms get noticeably hotter than the rest of the house by mid-afternoon, even with the AC running.
What it costs in Citrus
A typical 1,200-square-foot attic in Citrus runs $1,200 to $2,100 for blown-in insulation to reach R-38, based on our standard per-square-foot and attic-size pricing.
How we do it
We remove or flatten any damaged existing batts, check the venting, then blow insulation to a consistent depth across the full attic floor, keeping soffit vents clear.
Blown In Fiberglass Insulation
Signs you need it
You want a non-settling, mold-resistant insulation option that performs well in Citrus’s dry, high-heat attics.
What it costs in Citrus
Blown-in fiberglass in Citrus typically costs $1.50 to $2.30 per square foot installed, which works out to $1,800 to $2,760 for a 1,200-square-foot attic.

What Blown In Insulation Costs in Citrus
| Item | Typical range in Citrus |
|---|---|
| Blown-in cellulose (attic, R-38) | $1.00 – $1.70 per sq ft |
| Blown-in fiberglass (attic, R-38) | $1.50 – $2.30 per sq ft |
| Air sealing (attic penetrations, typical) | $400 – $900 depending on attic layout |
Prices in Citrus move up when we need to remove old, settled insulation first, when attic access is tight, or when venting has to be added before new insulation goes in. Our quotes are line-item and fixed before any work starts.
Does blown in insulation really lower cooling bills in Citrus?
Yes. Citrus attics hit 150°F regularly in summer, and upgrading from R-11 to R-38 blown-in insulation reduces heat transfer into living spaces. Most homeowners notice the difference the first heat wave. Call (833) 390-3099 for a specific estimate for your attic.
How long does a Citrus attic insulation job take?
A standard 1,200-square-foot attic takes one day of work in most cases. Prep, air sealing, and cleanup are all included. Larger attics or jobs requiring old-insulation removal may run two days.

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."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
