Insulation Company in Los Angeles, CA
Woolsey Insulation is an attic and spray foam insulation company serving Los Angeles, CA. We focus on two things: keeping hot air out of your attic in summer and giving you a written price before we touch anything. Los Angeles homes run hot. The San Fernando Valley regularly sees attic temperatures above 140°F, and South LA bungalows from the 1920s often have nothing but a few inches of dust between the ceiling and the roof. If your upstairs rooms bake by 2 p.m., the fix usually starts above your head. Call us at (213) 232-7269 and we’ll walk you through what your attic actually needs.
Why Los Angeles Homes Are Different
Los Angeles has three housing generations, and each one fails in its own way. The Craftsman and Spanish Revival homes built before 1940 in neighborhoods like Highland Park, West Adams, and Echo Park have charming bones and almost no attic insulation. Many were built with open soffits and no air sealing at all. The mid-century stucco tract houses across the Valley and Westchester got a thin blanket of fiberglass in the 1950s and 60s, now compacted and doing very little. Then there are the newer builds and remodels, which have to meet Title 24 energy code: R-38 attic insulation minimum. That’s roughly 12 to 14 inches of blown-in fiberglass or cellulose, and it’s the standard we work to even on older homes because Los Angeles cooling costs make it pay for itself fast.
The climate does something specific here: cooling loads dominate. Attic insulation in Los Angeles is mostly about stopping radiant heat from the roof deck pushing down into your living space. We don’t deal with frozen pipes or frost heave like cold-climate contractors do. We deal with attics that hit 140°F by mid-morning in Woodland Hills and bedrooms that never cool down at night in Baldwin Hills. Crews regularly schedule attic work before 10 a.m. from June through September because an unconditioned attic after noon is dangerous to work in. That heat is exactly what we’re insulating against.
Our Main Los Angeles Services
Most Los Angeles homeowners call us for one of two jobs. Each has its own dedicated page with full details and pricing.
Attic Insulation in Los Angeles
Attic insulation is the workhorse retrofit for older Los Angeles homes. We remove or level out what’s there, air seal the gaps around can lights, wiring penetrations, and the attic hatch, then blow in fresh material to the correct depth. In a 1920s Spanish Revival in Mid-City or a 1960s Valley ranch, this is typically a one-day job. The local twist is access: many older attics have tight hatches and low clearances, and the heat timing matters. We quote it honestly, tell you what depth you’ll get based on your framing, and put the number in writing before we start. See Attic Insulation in Los Angeles for full local pricing and job details.
Spray Foam Insulation in Los Angeles
Spray foam insulation is a two-part liquid that expands on contact and seals gaps airtight. In Los Angeles it’s often the right call for homes with cathedral ceilings, additions, or attics with ductwork up there, where the roof deck itself needs to be sealed and insulated. The material works differently than blown-in: it forms a continuous air barrier, not just a heat barrier. On hot August afternoons in neighborhoods like Sherman Oaks or Eagle Rock, that air seal is what keeps upstairs rooms from drifting up five degrees by dinnertime. We work with open-cell and closed-cell foams from trusted brands and quote every job with a written price. See Spray Foam Insulation in Los Angeles for how we handle this in L.A.’s older framing.

Brands We Service in Los Angeles
We install and service insulation from Owens Corning, Johns Manville, Knauf, and Rockwool. The right material depends on your attic’s framing, venting, and what’s already up there. Our crews stock the common blown-in and batt products locally, so most jobs don’t wait on a material order. You can see the full range on our brands page.
Pricing for Insulation Company in Los Angeles, CA
| Service | Typical range in Los Angeles |
|---|---|
| Attic insulation retrofit, 1,200 – 1,500 sq ft home | $1,800 – $3,200 |
| Air sealing + blown-in fiberglass, older bungalow | $1,400 – $2,400 |
| Spray foam attic, open-cell, 1,000 sq ft | $4,500 – $7,500 |

What pushes price up in Los Angeles is attic access: cramped hatches, low-pitch roofs, and the summer heat that shortens the safe work window all add labor. Homes with vermiculite or rodent-damaged insulation also need removal first, which is its own line item. Every Los Angeles job gets a written price before work starts. That number doesn’t change at the door. It’s the Kingswell way, and it’s been our standing rule as long as we’ve been in business.
Neighborhoods We Serve in Los Angeles
We work across the city, from the Valley to the Westside to South LA and the Eastside. Each neighborhood brings its own housing stock, so here’s a sense of where we’re regularly crawling into attics:
- Sherman Oaks and Studio City: mid-century ranch homes with compacted fiberglass
- Echo Park and Silver Lake: Craftsman-era hillside homes with minimal original insulation
- Mid-City and West Adams: Spanish Revival and bungalow stock with attic access quirks
- Woodland Hills and Tarzana: Valley heat makes attic work urgent and early-morning
- South LA: pre-1980 rentals and family homes where cooling bills spike in summer
Typical response for a Los Angeles estimate visit is same-week, with earlier slots available for urgent jobs like exposed wiring or a failed attic hatch. Call (213) 232-7269 and a live person will get you scheduled.

In most cases, adding or replacing attic insulation doesn’t require a city permit. If your project is part of a larger remodel that already has permits pulled, insulation is covered under that scope. We’ll flag it if anything about your job looks like it needs LADBS sign-off.

What Los Angeles Customers Say
"Spray foam in the crawlspace and new attic insulation. They wrote up the whole price and the two jobs came in exactly as quoted. Floors upstairs aren't freezing in the morning anymore."
- Nathan Pruitt"The guy didn't try to sell me on foaming the whole house. He said the attic was where I'd actually feel it and left it at that. Honest, and he was right, our bills dropped."
- Angela Ruiz"Drafty old house that never felt comfortable. After the attic and some air sealing it's a different place. On time, clean, and the quote didn't change. Wish I'd done it years ago."
- Dmitri Kozlov
