Insulation Company in Highgrove, CA
Blown in insulation solves the single most expensive problem in Highgrove homes: heat gain through attics that bake under Inland Empire sun. When attic temperatures push past 140°F in July and August, under-insulated ceilings transfer that heat straight into living spaces, forcing air conditioners to run constantly. East Los Angeles Insulation Co has served Highgrove since 2018, and we specialize in retrofitting mid-century ranch homes and older stucco houses with insulation that actually holds up to sustained triple-digit heat.

Why Highgrove Homes Are Different
Highgrove’s housing stock skews toward 1950s through 1970s ranch homes and single-story stucco construction, and most of those houses still carry whatever insulation the original builder decided was “good enough” decades ago. Our technicians regularly find attic insulation in Highgrove flattened to two or three inches, compressed by time and heat, with dusty gaps around recessed light cans and rodent tunnels cutting through what little coverage remains. The exterior stucco walls in these homes usually have no cavity insulation at all, which means the attic is doing all the thermal work, and it’s not doing much.
Unlike coastal Southern California cities where insulation gets sold as winter weatherization, Highgrove’s insulation equation runs in reverse. Long summers with sustained triple-digit temperatures and dry air mean the attic absorbs enormous solar load every single day. Blown-in fiberglass degrades and settles faster in this heat, so what was installed in 1962 is nowhere near what the label claimed. The real wins in Highgrove come from air-sealing the attic floor first, then adding blown-in cover over the old deteriorated layer to build R-value back up. That combination is what actually moves the needle on cooling bills here, not just adding more material on top of leaks.
Our Main Highgrove Services
Highgrove homeowners call us most often about two jobs: attic insulation upgrades and spray foam applications. Both address the same underlying issue, relentless attic heat, but they solve it differently.
Attic Insulation in Highgrove
Most Highgrove attics we inspect have settled fiberglass batts or thin blown-in material that’s lost its loft. Attic insulation here means removing and replacing degraded material, air-sealing penetrations like can lights and plumbing vents, and bringing the attic up to a level that actually resists radiant heat from the roof deck. The difference shows up immediately on the next utility bill. We carry multiple product lines so we’re not forcing one brand into every home. Learn more on our Attic Insulation in Highgrove page.
Spray Foam Insulation in Highgrove
For Highgrove homes with unvented attics, ductwork running through hot zones, or stubborn air leaks around the attic perimeter, spray foam is often the right call. Closed-cell foam adds structural rigidity and an air barrier in one pass, while open-cell works well for sound control and interior applications. We install Icynene and Demilec products, both with established field performance records in hot climates. See the Spray Foam Insulation in Highgrove page for specifics.
Blown In Insulation in Highgrove
Blown in insulation is the most common retrofit we perform in Highgrove, and for good reason. Older ranch homes and stucco houses in ZIP 92313 rarely have adequate attic coverage, and blown-in material can be added directly over existing insulation without tearing out ceilings or walls. In Highgrove’s heat, fiberglass degrades and settles faster than homeowners expect, so our approach starts with air-sealing the attic floor to stop conditioned air from escaping, then blowing fresh material to the correct depth for our climate zone. We install GreenFiber cellulose and fiberglass options depending on the application, and we’re one of the few contractors in the Highgrove area offering both. For detailed product information, see our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Highgrove homes built before 1980 with thin or settled attic insulation and rising summer cooling bills are prime candidates for dense-packed cellulose.
What it costs in Highgrove
Cellulose insulation in Highgrove typically runs $1.50 to $3.50 per square foot installed, depending on depth and whether we’re topping up or starting fresh.
How we do it
We air-seal the attic floor first, then blow GreenFiber cellulose to the target R-value using calibrated equipment, paying special attention to eaves and can-light clearances.
Blown In Attic Insulation
Signs you need it
If your Highgrove attic has original insulation that’s settled below the joist tops, or you can feel heat radiating through ceilings on summer afternoons, the attic needs attention.
What it costs in Highgrove
Blown in attic insulation in Highgrove usually falls between $1,800 and $4,200 for a typical 1,200 to 1,800 square foot ranch home, including air-sealing.
How we do it
We remove or repair damaged areas, seal penetrations and top plates, install baffles at soffit vents, and blow insulation to code depth with an even, consistent coverage.
Blown In Cellulose Insulation
Signs you need it
Homeowners in Highgrove who want a recycled-content, low-VOC option with better heat-resistance per inch than fiberglass often ask us about blown in cellulose specifically.
What it costs in Highgrove
Blown in cellulose runs $1.50 to $3.50 per square foot in Highgrove, with most attic jobs landing between $1,200 and $3,800 depending on existing conditions.
How we do it
We use GreenFiber cellulose, which includes a borate treatment for fire and pest resistance, blown to the manufacturer’s specified density for our climate zone.
Blown In Fiberglass Insulation
Signs you need it
If your Highgrove home has old, compressed fiberglass batts that have lost their R-value, blowing loose-fill fiberglass over the top is a fast, economical fix.
What it costs in Highgrove
Blown in fiberglass insulation in Highgrove typically costs $1.00 to $2.80 per square foot, with full attic retrofits averaging $1,500 to $3,500.
How we do it
We blow loose-fill fiberglass to the correct depth using a machine calibrated for consistent density, making sure coverage is even across the entire attic floor.
Loose Fill Insulation
Signs you need it
Highgrove attics with irregular joist spacing, lots of cross-bracing, or hard-to-reach corners are ideal for loose fill insulation that flows around obstacles.
What it costs in Highgrove
Loose fill insulation in Highgrove ranges from $1.00 to $3.50 per square foot depending on material choice, with most attic jobs between $1,200 and $4,000.
How we do it
We choose the right material for your attic layout, then blow it to the specified depth using laser-guided depth markers to ensure consistent R-value everywhere.

In Highgrove, two factors push prices up more than anything else: attic accessibility and how much old insulation has to be removed before new material goes in. The heat itself doesn’t change material costs, but homes with tight attic hatches, low clearance, or rodent-damaged insulation take longer to prep. Every quote we give is upfront and covers the full job, no hourly surprises.

What Highgrove 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."
- Jason Walsh"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
- Rosa Martinez"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
