Fast, Reliable Spray Foam Insulation Across Burbank
Spray foam insulation in Burbank typically costs $2,800 to $7,500 for a full attic job, with flat-roof addition work running higher because of the access work involved. We get calls from Magnolia Park, the hillside pockets above 91501, and the post-war tracts off Victory every week, usually from homeowners whose upstairs rooms won’t drop below 90°F in August. Hollywood Insulation Co has been working in Burbank long enough to know that most of these homes were built between 1940 and 1955, and most left the factory, so to speak, with little or nothing between the living space and that Valley sun. Call (866) 605-6949 and we’ll give you an honest read on what’s actually going on in your attic.
Why Hollywood Insulation Co Is Burbank’s Preferred Spray Foam Insulation Company
Burbank homeowners call us because we’re a dedicated insulation shop, not a general contractor who happens to carry a foam rig. Every technician on our crew does one thing: insulating homes. That focus shows up fast in Burbank’s older housing stock, where the job is rarely simple. We’ve worked in enough 1940s Lockheed-era bungalows and 1950s stucco boxes to know what’s waiting behind the drywall and above the ceiling.
Our reputation in the city has been built the slow way: showing up on time, diagnosing the real problem, and fixing it without overselling. Burbank homeowners tend to do their homework before calling, and they usually know roughly what they’re looking for. What they don’t always know is whether open-cell or closed-cell foam is right for their specific roof pitch, attic access, or wall assembly. That’s the conversation we have every day.
We respond to most Burbank estimates within one business day, and because we carry both Icynene and Demilec spray foam systems, we’re not steering you toward whatever’s loaded on the truck. The recommendation is matched to your house. Noel Camacho runs our shop with a simple rule: install the right material for the structure, not the most convenient one.
Spray Foam Attic Insulation in Burbank
Spray Foam Attic Insulation in Burbank usually costs between $2,800 and $6,900 depending on square footage, roof pitch, and whether the attic has standard pull-down access or needs a hatch cut. In most of Burbank’s 1920s-to-1950s homes, we’re dealing with attics that hit 140°F to 160°F by mid-afternoon from late May through October. The foam’s job here is not winter warmth. It’s stopping radiant heat from baking through the ceiling into the bedrooms below.
The typical Burbank attic we see has R-0 to R-9 of old compressed fiberglass, if anything at all. Ducts run through that same superheated space, so the air coming out of your registers is fighting a losing battle before it reaches the room. We address this by air-sealing first, then applying the foam. Sealing the top plates, wire penetrations, and chase openings before spraying is the difference between a foam job that works and one that just hides the problem under a layer of plastic.
Flat-Roof Addition Attics
The flat-roof additions common off Magnolia Boulevard and Olive Avenue hide something most other Valley cities don’t deal with: zero attic access. There’s no pull-down stair, no scuttle, often no void big enough to crawl into at all. When a homeowner tells us the back bedroom is 10 to 15 degrees hotter than the front of the house, that flat roof is usually the culprit. We cut a roof hatch or work through a gable cut, then spray closed-cell foam directly against the underside of the roof deck to insulate and stop the radiant bake in one pass.
R-0 Attic Cap-Over
In the original 1940s and 1950s sections of Burbank homes, the attic floor often has no real insulation at all. We’re simply capping a scorched space. Our crews have measured attic floors at 150°F while the ceiling below was radiating heat like a low oven. Open-cell Icynene is a common choice here because it fills the irregular joist bays of older construction and air-seals as it expands.
Spray Foam Wall Insulation in Burbank
Spray Foam Wall Insulation in Burbank typically runs $3,200 to $8,400 for a whole-home retrofit, with individual wall cavities or rim joist sections priced much lower. Burbank’s older stucco bungalows have uninsulated wall cavities in most cases. The stucco itself is a thermal mass, which helps a little, but once the sun has been on that west-facing wall all afternoon, the interior surface is hot to the touch by 6 p.m. Closed-cell foam inside those 2×4 cavities makes a measurable difference in how hot the wall gets and how hard your AC works.
Wall work in Burbank is rarely a tear-out job. We usually access the cavities either from the exterior by removing a band of stucco, or from the interior by cutting small access points between studs. The latter is more common on the hillside homes in 91501 where exterior access is tight and the wall assemblies are original. We foam, patch, and leave the wall ready for paint.
Rim Joist and Band Board Sealing
The rim joist area, where the floor framing meets the foundation, is a major air leak in almost every older Burbank home. In the flat lots of 91501 and 91502, we frequently find rim joists that were never sealed at all. Closed-cell foam injected along the band board stops that stack-effect draft and keeps conditioned air from escaping through the floor edges.
Garage-Adjacent Wall Cavities
Bedrooms that share a wall with a garage are common in Burbank’s post-war tracts. That wall is rarely insulated and the garage hits 120°F in summer, turning the bedroom against it into an oven. We can inject foam into those cavities without opening the whole wall, and the temperature difference in the bedroom is usually noticeable the same week.
Trusted Brands We Service in Burbank
We install Icynene and Demilec spray foam systems in Burbank because they’re two of the most specified spray polyurethane foam brands in North America. Each covers a different application: Icynene’s open-cell foam is excellent for attic floors and air-sealing irregular older framing, while Demilec’s closed-cell line handles flat roofs, rim joists, and anywhere moisture or structural strength matters. We keep the local supply chain tight so Burbank jobs don’t stall waiting on material. Spray Foam Insulation is what our technicians do every day, which means we can quote accurately and install without surprises.
Common Spray Foam Insulation Problems We See in Burbank Homes
- Foam sprayed over knob-and-tube-era wiring without air-sealing first. The original 1950s homes often still have old wiring penetrations and single-pane aluminum slider gaps. Foam hides those bypasses without closing them, and the attic keeps baking the house. We always seal the actual holes and plates before spraying.
- Closed-cell foam applied to a flat roof deck with no moisture plan. A low-pitch or flat roof over a 1950s stucco assembly traps moisture if the foam goes on without accounting for how the roof sheds water. Done wrong, this rots the deck. Done right, closed-cell foam acts as both insulation and a secondary water control layer.
- Quoting a standard pull-down-stair job on a Magnolia or Olive flat-roof addition. These additions commonly have zero attic access. A crew that arrives expecting a standard stair will have no hatch, no gable-cut plan, and a homeowner left waiting. We verify access before we quote.
- Foam covering active ceiling leaks or roof damage. In Burbank’s older flat-roof and low-pitch homes, water intrusion from aging roofing is common. Spray foam will not fix a leaky roof, and it will hide the damage until it’s worse. We inspect the roof condition before recommending foam on any deck application.
Pricing for Spray Foam Insulation in Burbank, CA
Here are honest numbers for the Burbank market. A standard open-cell attic spray job in a 1,200 to 1,800 square-foot bungalow runs $2,800 to $5,200. A flat-roof addition with no existing access runs $4,500 to $8,500 because the hatch cut, air-sealing, and closed-cell foam against the deck add real labor and material. Wall cavity injection runs $12 to $22 per square foot of wall area depending on wall depth and access. Rim joist sealing runs $1,100 to $2,400 for a typical Burbank crawlspace perimeter. These are not quotes, they’re ranges from jobs we’ve actually done in 91501, 91502, 91523, and the streets around the studios. Call (866) 605-6949 and we’ll give you a firm number, free.

FAQs About Spray Foam Insulation in Burbank
Yes. We do this regularly in the flat-roof additions off Olive and Magnolia. If there’s no pull-down stair or scuttle, we cut a roof hatch or work through a gable cut, air-seal the top plates and penetrations, then spray closed-cell foam against the underside of the roof deck. This is not a problem for our crew; it’s a routine part of working in Burbank’s older housing stock. Call (866) 605-6949 and we’ll confirm your specific access situation before quoting.
In most Burbank homes, spray foam alone fixes the problem because the heat source is radiant gain through an uninsulated attic. On a 1951 stucco bungalow off Magnolia Boulevard near Magnolia Park, our crew found a flat-roof rear addition with no attic access at all. The upstairs room held steady at 95°F. We cut a roof hatch, air-sealed the top plates, and sprayed two inches of closed-cell Icynene against the flat roof deck. The room dropped into the low 80s within days. Radiant barriers help on vented attics, but foam both insulates and air-seals, which radiant barrier does not.
Spray foam should not go directly over active knob-and-tube wiring, and any competent Burbank insulation contractor will tell you the same. We inspect for old wiring before spraying and we either work around it or recommend an electrician address it first. The bigger issue is usually the air leaks around those old wiring penetrations, which we seal properly before any foam goes in. Skipping that step is what causes foam jobs to underperform in these older homes.
It depends on the attic and the roof. In vented attics over the original 1940s-to-1950s Burbank sections, we typically use open-cell Icynene to fill the irregular joist bays and air-seal the ceiling plane. On flat-roof additions and areas where a roof deck needs direct application, we use closed-cell Demilec, which adds structural strength and controls moisture. We carry both systems and choose based on your specific house, not on what we happen to have loaded.
Installing spray foam in your attic or walls does not void most builder warranties, but you should check your specific warranty language before scheduling. We can walk you through what we’re doing, where we’re doing it, and document the installation for your records. Most Burbank homeowners with builder-grade homes find the comfort improvement is worth any warranty paperwork. Call (866) 605-6949 and we’ll go over your specific situation.
