Insulation Company in Irwindale, CA
Blown in insulation in Irwindale solves the core problem most homeowners here deal with: attics that hit 150°F in summer while the living space below struggles to stay comfortable. Older homes built between the 1950s and 1970s in the 91722 ZIP often have compacted fiberglass batts that stopped working years ago. North Tustin Insulation matches the material to your home, not the other way around. We carry Owens Corning, GreenFiber, Demilec, and Johns Manville products so the recommendation fits your walls and attic, not whatever happens to be on the truck. Call (877) 265-5712 for a free estimate.
Why Irwindale Homes Are Different
Irwindale sits in a part of the San Gabriel Valley that traps heat and airborne particles. Summer temperatures regularly cross 100°F, and the mountains to the north block the coastal breeze that cools other parts of Los Angeles County. That means attics here routinely exceed 150°F, which accelerates how fast fiberglass batts degrade and settle. We see it constantly: a home built in 1965 still has its original R-11 batts, compressed to maybe R-4 in spots, and the homeowner is running the AC nonstop from June through October.
Air quality is another factor specific to Irwindale. Proximity to industrial operations and the valley’s inversion layer means dust, smog, and pollen hang around longer than they do in coastal cities. Loose-fill insulation, when installed at the right density, reduces air infiltration through the attic floor and exterior walls. That’s the difference between a house that feels sealed and one where you can smell the outside air every time the wind shifts. Older single-family homes dominate the housing stock here, with minimal original insulation and often no air sealing at all. Newer infill construction and industrial buildings have their own needs, usually temperature control and noise reduction, which call for different materials and methods.
Our Main Irwindale Services
Most Irwindale homeowners call us about two things: an attic that’s either empty or under-insulated, and a desire for the highest-performing seal possible. Both are covered in more detail on their own pages.
Attic Insulation in Irwindale
Attic insulation is the highest-impact upgrade for most Irwindale houses because heat rises and the attic is where the battle is won or lost. We inspect what’s already up there, measure settled depth, and recommend either a full removal or a top-up depending on condition. Homes in the 91722 ZIP with original 1960s batts usually need more than a top-up; they need the old material out and a clean start. In summer, this is the difference between an upstairs hallway that’s tolerable and one you avoid. See Attic Insulation in Irwindale for specifics on methods and materials.
Spray Foam Insulation in Irwindale
Spray foam earns its cost in Irwindale when homeowners want air sealing and insulation in one step. Closed-cell foam adds structural rigidity and acts as a vapor barrier, which matters in the valley’s dry, dusty conditions. We install Demilec and Icynene systems, both open-cell and closed-cell, depending on the assembly. For attached garages, rim joists, and vaulted ceilings, spray foam fills gaps that batts and loose fill simply can’t reach. Read the full breakdown at Spray Foam Insulation in Irwindale.

Blown In Insulation in Irwindale
Blown in insulation is the most common service we perform in Irwindale because it’s the fastest way to bring an older home up to modern standards without tearing out drywall. Most houses here have attic access through a small ceiling hatch, and loose-fill material goes in quickly through a hose, filling every gap and cavity in a couple of hours. We’re an insulation-only contractor, and our Blown In Insulation work covers cellulose, fiberglass, and loose-fill applications matched to the home’s framing and the valley’s heat demands. Call (877) 265-5712 to schedule an attic inspection.
Cellulose Insulation
Signs you need it
Your attic insulation is settled, dusty, or barely covers the ceiling joists, and your AC runs constantly from May through October.
What it costs in Irwindale
Blown-in cellulose retrofit work typically runs $1.20 – $4.60 per square foot depending on existing material that must be removed first.
How we do it
We air-seal the attic floor penetrations, then dense-pack or loose-fill GreenFiber cellulose to the R-value Irwindale’s climate calls for.
Blown In Attic Insulation
Signs you need it
Rooms below the attic are 8 – 12°F hotter than the rest of the house, and you can feel heat radiating through the ceiling on summer afternoons.
What it costs in Irwindale
An attic blow-in job in Irwindale generally lands between $2,800 and $7,500 for a typical 1,500-square-foot house.
How we do it
We remove or level existing material, install baffles at the eaves, and blow loose-fill fiberglass or cellulose to a uniform, measured depth.
What Blown In Insulation Costs in Irwindale
| Item | Typical range in Irwindale |
|---|---|
| Blown-in cellulose (full attic, existing material present) | $1.20 – $4.60 per sq ft |
| Blown-in attic insulation (typical 1,500 sq ft home) | $2,800 – $7,500 |
| Blown-in fiberglass retrofit (attic) | $1.00 – $3.80 per sq ft |
Can blown in insulation be added over old insulation in Irwindale?
It depends on the condition of the old material. Crushed, water-stained, or pest-damaged insulation should come out first. If the existing batts are dry and intact, blowing new material over them works and saves money. Call (877) 265-5712 for an attic inspection.
How long does a blown in insulation job take in Irwindale?
A typical 1,000 to 1,800 square foot attic takes three to five hours from setup through cleanup. More time is needed if we’re removing old insulation first or air-sealing extensively. Estimates are free.
