Insulation Company in Citrus, CA
Blown in insulation is the most common retrofit we handle in Citrus, because so many homes here were built between the 1950s and 1970s with barely enough attic insulation to pass code at the time – and code then was nothing like what the San Gabriel Valley foothill heat demands now. We’re Birch Insulation, and we’ve served Citrus since 2015 matching older attics to the right material, whether that’s cellulose fill, fiberglass, or a spray foam upgrade. If your upstairs rooms bake in August and your AC never cycles off, call (866) 511-7592 and we’ll tell you exactly what’s in your attic now and what it would take to fix it.
Why Citrus Homes Are Different
Citrus sits right against the Angeles National Forest edge, and that changes insulation work in ways a contractor from the flatlands won’t always account for. Summer days here routinely cross 100°F, and when the Santa Ana winds kick up in fall, they push dry, abrasive dust down the canyon and into any gap in your building envelope. Old attics in Citrus aren’t just under-insulated – they’re often sun-baked to the point where original fiberglass batts have compressed, darkened, and lost most of their R-value. Add in the wildlife and dust that come through soffit vents exposed to the forest edge, and a standard “blow more on top” approach misses half the problem. Citrus attics need air-sealing plus radiant-heat rejection, and the material has to hold up under wind-driven dust. Most of the mid-century tract homes and stucco-on-wood-frame ranch houses you see throughout the 91702 area have the same original attic layout: shallow ceilings, low-slope roofs, and no exterior vent baffles worth the name. That means we’re usually rebuilding the attic’s ventilation story at the same time we’re adding insulation, because one doesn’t work without the other here.
Our Main Citrus Services
Two jobs account for most of the insulation calls we run in Citrus: attic retrofits for older homes losing conditioned air through degraded insulation, and spray foam when homeowners want air sealing and the highest R-value per inch in one pass.
Attic Insulation in Citrus
Most Citrus attics we open up have original blown glass or thin batt insulation that settled decades ago, often down to R-11 or less in homes that should be carrying R-38 to R-49 given the foothill summer load. The work involves sealing bypasses around recessed lights, top plates, and vent penetrations, then installing fresh material across the full floor. On a 1950s tract home or 1970s ranch, this is the single highest-return upgrade you can make for upper-floor comfort and cooling cost. Full details and local pricing are on our Attic Insulation in Citrus page.
Spray Foam Insulation in Citrus
Spray foam makes particular sense in Citrus attics where the roof deck gets baked by direct foothill sun and dust intrusion through gable and soffit vents is a recurring nuisance. Closed-cell foam on the roofline converts the attic to conditioned space and blocks wind-driven particulate from the forest edge, while open-cell Icynene is often a better value for interior walls and sound control. We install both Icynene and Demilec, so the recommendation follows the house, not our inventory. See Spray Foam Insulation in Citrus for costs and methods.

Blown In Insulation in Citrus
Blown in insulation is the workhorse retrofit for Citrus’s older housing stock: it’s fast, it fills the odd cavities and shallow pitches common in 1950s and 1960s construction, and it can push an under-insulated attic from R-11 to R-49 in a single day. Our team handles blown in insulation with cellulose and fiberglass, and we match the material to what your attic actually needs – because a wind-dusty Citrus attic with open soffit vents needs different treatment than a sealed attic in a newer development.
Cellulose Insulation
Signs you need it
Your attic’s existing insulation looks thin, settled, or dusty, and your cooling bills climb every summer while upstairs rooms stay hot.
What it costs in Citrus
Blown-in cellulose in Citrus typically runs $1,400 to $3,100 for a full 1,200 to 1,800 sq ft attic upgrade, including the prep we do on older stucco homes.
How we do it
We air-seal the big bypasses first, then dense-pack or loose-blow GreenFiber cellulose to spec across the attic floor or into wall cavities.
Blown In Attic Insulation
Signs you need it
Rooms directly under the roof get 10 to 15 degrees hotter than the rest of the house, and your attic floor shows bare decking between old batts.
What it costs in Citrus
An attic blow-in on a typical Citrus ranch home runs $1,200 to $2,800 for the full floor, with final price set by access, depth, and whether we’re removing old material first.
How we do it
We stabilize or remove degraded old insulation as needed, install vent baffles at the eaves, seal bypasses, then blow Owens Corning fiberglass or GreenFiber cellulose to R-38 or R-49.
Blown In Cellulose Insulation
Signs you need it
You want a recycled-content option that slows air movement better than fiberglass, and your attic has irregular bays or odd framing that needs dense coverage.
What it costs in Citrus
Budget $1,400 to $3,100 on a Citrus attic, and we’ll adjust the depth and density based on your roofline and the forest-edge dust exposure.
How we do it
We run GreenFiber cellulose through our blower rig to the precise R-value your attic plan calls for, then top-dress problem areas near vents and baffles.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old fiberglass batts that have fallen or compressed, and you want a fresh, consistent layer that won’t settle like the original install.
What it costs in Citrus
Blown fiberglass in Citrus typically runs $1,200 to $2,800, similar to cellulose, though depth and existing-material removal move that number.
How we do it
We remove or stabilize the old material, seal attic bypasses, and blow Johns Manville or Owens Corning fiberglass to a consistent depth across the floor.
Loose Fill Insulation
Signs you need it
Your attic has shallow joists, lots of cross-bracing, or hard-to-reach corners that batts can’t fit without gaps and voids.
What it costs in Citrus
Loose fill in Citrus attics falls in the $1,200 to $3,100 band, with the lower end for simple top-offs and the higher end for full removal and reseal work.
How we do it
We blow loose cellulose or fiberglass across the entire attic floor, then use a thermal check to confirm even coverage and no bare spots.

How much does blown in insulation cost in Citrus?
Most Citrus homes fall between $1,200 and $3,100 for a blown-in attic job. The spread is driven by existing-material removal, attic access, and whether vent baffles and air sealing are included. Call (866) 511-7592 for a square-footage quote on your home.
Can you remove old insulation before blowing in new material in Citrus?
Yes, and on many Citrus attics built in the 1950s and 60s it’s the right call – old material is often dust-loaded and compressed. We’ll tell you plainly if removal is warranted or if a clean top-off is enough. Call (866) 511-7592 to set up an attic check.

What pushes a Citrus attic toward the top of those ranges? Foothill dust and decades of wildlife traffic make old-material removal common, and on stucco-on-wood-frame homes the bypass sealing takes longer than on newer construction. We give every Citrus project an upfront, line-item quote before work starts – you’ll know the price before we put a single hose in the attic.

FAQs About Insulation Company in Citrus
We schedule most Citrus estimates within one to two business days, and on emergency work where an attic is open to the elements or spray foam just cured wrong, we’ll run same-week. Call (866) 511-7592 before noon and there’s a good chance we can get eyes on your attic by the next afternoon.
Most Citrus HOAs don’t regulate interior attic work beyond requiring contractors to have proper insurance and to keep materials out of common areas. Attic retrofits inside the shell of the home typically don’t need architectural review, but if your HOA has specific rules, we’ll work within them and keep the site clean during install. If your board needs a material spec sheet, we can provide one from any of the brands we carry.

For your home, call (866) 511-7592 and we’ll give you a straight answer on material and cost.

What Citrus Customers Say
"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."
— Neil Hayes"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."
— Allen Kim"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Katie Whitaker
