Insulation Company in Boyle Heights, CA
Blown in insulation is the most common call we get from Boyle Heights homeowners, and for good reason. The neighborhood’s early-1900s bungalows and Spanish Colonial Revival cottages were built when insulation was an afterthought, leaving attics and walls that bake in summer and leak conditioned air year-round. Laguna Hills Insulation has served Boyle Heights since 2014, retrofitting older homes with blown in cellulose and fiberglass where access is tight and lath-and-plaster walls demand a lighter touch.

Why Boyle Heights Homes Are Different
Boyle Heights sits in the semi-arid LA basin, and the numbers tell the story: long dry summers pushing attic temperatures past 140°F, mild winters that barely dip into heating territory, and smoke days that make air sealing a health consideration, not just an energy one. The housing stock ranges from 1900s-1940s Craftsman bungalows and Spanish Colonial Revival cottages to postwar stucco apartments, many with rear additions and converted garages serving as living space or casitas. That means we’re almost never working on code-driven new construction. We’re retrofitting homes where the original build had no insulation at all, where knob-and-tube wiring limits what can be blown where, and where old lath-and-plaster requires a careful hand. Flat-roofed garage conversions along streets like 1st Street absorb heat all afternoon, and tight shared lots leave almost no staging room. Spanish-speaking crews make a real difference on Boyle Heights jobs; family referrals drive most of the work here, and we staff bilingual installers as a matter of course.
Our Main Boyle Heights Services
Most Boyle Heights homeowners reaching out to us are comparing two approaches for their older homes: attic insulation to stop radiant heat pouring down from sun-baked roof decks, or spray foam when gaps, cracks, and air leakage are the bigger problem. Both are installed in-house.
Attic Insulation in Boyle Heights
In the flat-roof and low-pitch attics common across 90023, the attic acts like a solar oven. By mid-afternoon, the air up there can exceed 140°F, and that heat radiates straight through uninsulated ceilings into the rooms below. We blow in fiberglass or cellulose over the attic floor in the typical Boyle Heights bungalow, seal the gaps where wiring and framing break the air barrier, and make sure the old ventilation is actually doing its job. Attic Insulation in Boyle Heights covers what we see on these jobs and how long retrofits typically take.
Spray Foam Insulation in Boyle Heights
Converted garages and rear additions in Boyle Heights often have wall cavities that are too shallow or too irregular for batts, and a roofline that leaks air through every seam. Closed-cell spray foam solves both at once: it air-seals and insulates in a single pass, which matters when a casita shares a wall with a neighbor’s lot line and there’s no attic to treat. We install Icynene and Demilec open- and closed-cell systems for these tighter, less forgiving spaces. Spray Foam Insulation in Boyle Heights explains the options and where each foam type fits best.

Blown In Insulation in Boyle Heights
Blown in insulation is the workhorse retrofit for the 1900s-1940s homes that define Boyle Heights. Most of these bungalows left the factory, so to speak, with empty wall and ceiling cavities, and the drill-and-fill approach lets us insulate finished walls without tearing out original lath-and-plaster. We install Blown In Insulation in attics, sidewall cavities, and the awkward framing bays common to rear additions and converted garages across 90023.
Cellulose Insulation
Signs you need it
Rooms stay hot long after sunset and your cooling bills climb all summer, even though the attic above has some batts that were probably installed decades ago.
What it costs in Boyle Heights
Dense-packed cellulose for walls and attics in Boyle Heights typically runs $1.50 to $3.50 per square foot installed, depending on cavity depth and access.
How we do it
We drill access holes through exterior stucco or interior plaster, blow GreenFiber or Johns Manville cellulose to the target density with a high-pressure hose, then patch and match the surface.
Blown In Attic Insulation
Signs you need it
The second floor or ceiling plane feels noticeably warmer than the living space below by early afternoon, and the attic above is either bare or carries a thin, settled layer of old fiberglass.
What it costs in Boyle Heights
Blown in attic insulation over the attic floor in Boyle Heights generally runs $1,000 to $2,400 for a typical 1,200-square-foot bungalow roof footprint.
How we do it
We air-seal the attic floor penetrations, set depth markers, and blow loose-fill fiberglass or cellulose to the R-value the house needs for LA basin cooling loads.
Blown In Cellulose Insulation
Signs you need it
Your existing attic insulation has compacted to a fraction of its original depth, and you notice drafts around old recessed light fixtures and ceiling junction boxes.
What it costs in Boyle Heights
Blown in cellulose to top off or fully re-insulate a Boyle Heights attic typically ranges from $1.20 to $2.80 per square foot installed.
How we do it
We remove or work around damaged material, then blow cellulose to a uniform depth that corrects the settle-and-sag pattern common in 1920s ceiling assemblies.
Loose Fill Insulation
Signs you need it
Temperature swings between rooms suggest uneven coverage, and you can see bare spots or low troughs in the existing loose fill from the attic hatch.
What it costs in Boyle Heights
Loose fill fiberglass in Boyle Heights attic cavities typically costs $0.80 to $2.00 per square foot, with denser applications at the higher end.
How we do it
We calculate the open volume, confirm ventilation is clear, and blow loose fill in a controlled pass that keeps the soffit vents unblocked.

FAQs About Insulation Company in Boyle Heights
Most blown in attic jobs finish in a single day, and wall or spray foam retrofits usually take one to two days. We schedule Boyle Heights estimates within the week and can often start within seven to ten days of a signed proposal.
For straightforward attic and wall insulation retrofits, no permit is typically required in Boyle Heights. If we’re adding insulation as part of a larger remodel or a converted garage legalization, the city may ask for plans, and we’ll flag that before any work starts.
Yes, regularly. Boyle Heights has a high proportion of converted garages and unpermitted rear additions, and we treat each one as its own retrofit: checking the existing roof assembly, air sealing what we can, and recommending insulation that won’t trap moisture in the older framing.
