Insulation Company in Boyle Heights, CA
Blown in insulation is the workhorse retrofit for Boyle Heights homes, and it’s what we do most often in the 90023 ZIP code. The neighborhood’s 1910s and 1920s bungalows and duplexes rarely have any insulation in their walls, and attics that do have coverage usually carry a thin, settled layer that stopped doing its job a decade ago. We blow cellulose or fiberglass into enclosed cavities, floors, and attics so the house finally holds its cool air in summer and stays warmer on winter nights. If your energy bills spike in August and the upstairs rooms never quite cool down, call us at (844) 241-0737. We work across Boyle Heights from the flats near Soto Street up to the hills east of Lorena.
Why Boyle Heights Homes Are Different
Boyle Heights sits inland-adjacent, just east of downtown Los Angeles, which means it catches the warm basin air that lingers well after sunset. Summers here run hot through the evening, and the shallow, uninsulated attics typical of the area turn that heat into a radiator over every bedroom ceiling. The homes themselves are another factor. Most of the housing stock dates to before 1940: wood-frame bungalows, duplexes, and small apartment courts with plaster-and-lath walls instead of drywall. Drilling into those walls for blown in insulation takes a careful hand, and crews that only know new construction tend to struggle the first time they meet an original lath strip.
What surprises most homeowners is how small the attic access usually is. In many of these pre-war bungalows around 90023, the attic hatch sits inside a hallway or bedroom closet, and the attic itself may be only three or four feet at the peak. A technician often works on knees or back, moving slowly around original framing. Many attics still have knob-and-tube wiring in place, and any insulation work has to keep clear of it rather than burying it under a fresh layer. That detail alone changes how a retrofit gets planned, and it’s why Boyle Heights jobs reward crews who have worked on older Los Angeles housing stock before.
Our Main Boyle Heights Services
Boyle Heights homeowners call about three things most often: attics that bake the rooms below them, walls with no insulation at all, and floors that leak cold air in winter. These two services cover nearly all of those calls.
Attic Insulation in Boyle Heights
Attic work in Boyle Heights usually means working around shallow framing, closet hatches, and original wiring that needs to stay visible. We air-seal the attic floor first, then add insulation to the depth that makes sense for the home’s age and roofline. Most 90023 attics have far less coverage than current recommendations, especially in homes that still carry their original ceiling joists. Bringing the R-value up changes how the whole house holds its temperature. Learn what the process looks like on our dedicated Attic Insulation in Boyle Heights page.

Spray Foam Insulation in Boyle Heights
Spray foam tackles what blown in cannot: odd-shaped crawl spaces, exposed basement rim joists, knee walls, and framing cavities that are too irregular for loose fill. Boyle Heights homes built into the hillsides often have a raised foundation on one side and slab on the other, and foam seals those transition points better than anything else. Our installers work with Icynene and Demilec systems, both open-cell and closed-cell, depending on the zone. See where foam fits in a Boyle Heights house on the Spray Foam Insulation in Boyle Heights page.

Blown In Insulation in Boyle Heights
Blown in insulation is the most practical retrofit for pre-1940 Boyle Heights homes, and we recommend it constantly. The walls in these bungalows and duplexes sit empty, and drilling small access holes to blow loose fill into each stud bay is far less invasive than opening up plaster walls. In attics, a thick blown in blanket over the existing layer restores performance fast. The Blown In Insulation method works with either cellulose or fiberglass, and we match the material to the home rather than defaulting to one product for every job.
Cellulose Insulation
Signs you need it
Rooms above unconditioned space run five to ten degrees hotter than the rest of the house in summer, and you can feel drafts near baseboards in winter.
What it costs in Boyle Heights
Expect $1.50 to $3.50 per square foot for dense-packed cellulose in walls, depending on access and cavity condition.
How we do it
We drill small holes through plaster or siding at each stud bay, blow GreenFiber cellulose to the right density, then patch and touch up the access points so they disappear.
Blown In Attic Insulation
Signs you need it
The current attic insulation sits below the tops of the joists, or it has compressed, darkened, and settled into thin patches over the years.
What it costs in Boyle Heights
Most Boyle Heights attics run $1.80 to $3.00 per square foot for a fresh blown in layer, and smaller attic hatches add a modest access charge.
How we do it
We air-seal the attic floor penetrations first, then blow loose fill to a consistent depth across the whole attic, working around existing framing and keeping clear of any active wiring.
Blown In Cellulose Insulation
Signs you need it
Your home has settled fiberglass in the attic but still feels drafty in winter, and you want a denser material with better air-blocking behavior.
What it costs in Boyle Heights
Blown in cellulose for an existing attic starts around $2.00 per square foot and rises with depth and prep work, particularly where access is tight.
How we do it
We run a hose from the truck to the attic, blow GreenFiber cellulose to the specified depth, and level it in sections so coverage stays even from eaves to peak.
Blown In Fiberglass Insulation
Signs you need it
The attic has old batts that no longer fill the joist bays, or you want a lighter loose fill option without cellulose settle-in behavior.
What it costs in Boyle Heights
Loose fill fiberglass runs about $1.20 to $2.60 per square foot for a standard open attic, with tighter spaces quoted after we see the access.
How we do it
We blow fiberglass to the required density, fluff it to the target depth, and install baffles at the eaves so vents stay open and airflow keeps working.
What Blown In Insulation Costs in Boyle Heights
| Item | Typical range in Boyle Heights |
|---|---|
| Blown in attic insulation | $1.80 – $3.00 per sq ft |
| Dense-packed wall insulation | $1.50 – $3.50 per sq ft |
| Cellulose attic retrofit | $2.00 – $3.50 per sq ft |
Does blown in insulation settle in Boyle Heights attics?
Cellulose settles slightly after installation, which we account for by blowing to the settled depth printed on the bag. Fiberglass settles less, but both hold their R-value when installed correctly.
Is blown in insulation safe around old wiring?
We treat knob-and-tube wiring as a work-around condition, never covering it. Cellulose and fiberglass are non-conductive, but the heat generated by old wiring means clearance comes first. Call (844) 241-0737 if you suspect your attic has original wiring.
