Insulation Company in Burbank, CA
Blown in insulation solves the two problems Burbank homeowners complain about most: rooms that bake in the eastern Valley heat and houses that never really get quiet. Burbank’s mix of 1920s bungalows, 1950s tract ranches, and newer infill townhomes means most homes were built for an era before insulation standards existed or under codes that are now decades out of date. Porch Light Insulation has served Burbank since 2014, matching the right material to each house rather than installing whatever is on the truck. Call us at (877) 521-4987 for a free estimate.
Why Burbank Homes Are Different
Burbank sits in the hot, smoggy eastern San Fernando Valley, where summer highs routinely push past 100°F and the valley traps heat well after sundown. That means attic insulation here pays off faster than in coastal LA, because the temperature delta between a 110°F attic and a 75°F living room works against your air conditioner for months at a time. Winter cold snaps matter too, and the Valley’s wide temperature swings mean draft sealing and air movement control are just as important as R-value.
The housing stock complicates things. Magnolia Park and the Rancho Equestrian district are full of 1920s to 1940s Spanish Revival homes and bungalows that often have nothing in the walls and thin, degraded batts in the attic. Many mid-century additions on the north side have flat-roof or low-pitch sections that make traditional vented attic assumptions dangerous. And the big one: Burbank sits directly under the Hollywood Burbank Airport flight corridor and adjacent to Warner Bros., Disney, and NBC soundstages. A large share of our Burbank jobs are as much about acoustic isolation as thermal performance. Contractors who do not understand that distinction miss what Burbank clients actually want.
Our Main Burbank Services
Most Burbank homeowners call us about two things: attic insulation that is either missing or shot, and spray foam for the tricky spots where air leaks and noise come through. Here is what each involves.
Attic Insulation in Burbank
Burbank attics are where most thermal loss happens, especially in older homes where original insulation has settled to a fraction of its rated value. We inspect what is up there, remove anything compromised, air-seal the gaps, and install material matched to your roof pitch and venting situation. Flat-roof and low-pitch sections on mid-century additions need special care so we do not trap moisture where venting is limited. See more on Attic Insulation in Burbank.
Spray Foam Insulation in Burbank
Spray foam is the answer for Burbank homes where air leaks and noise are the real problem. Closed-cell foam air-seals and insulates in one step, which matters in older walls with no cavity insulation and in crawlspaces that pull hot air from the ground. Open-cell foam works well for interior walls when sound from the flight corridor or a busy street keeps you up. We install both, and we will tell you honestly which fits your house.

Blown In Insulation in Burbank
Blown in insulation is the most common fix we install in Burbank attics, because it is the fastest way to bring an older home up to a useful R-value without tearing into walls or rebuilding the roof plane. In Magnolia Park bungalows and 1950s ranches alike, loose-fill fiberglass or cellulose can be blown over existing batts or into empty cavities, filling the odd-shaped voids and shallow rafter bays that make Burbank’s older attics so inefficient. For homes under the airport flight path, a dense-packed wall cavity also cuts the low-frequency rumble that batt insulation never touches. We blow it loose in attics and dense-pack it in walls, depending on what the house needs. Learn more about the method on our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation has settled below the top of the joists, or your upstairs rooms swing from hot to cold with the furnace and AC.
What it costs in Burbank
Blown-in cellulose in a typical Burbank attic runs $1,200 – $3,100, depending on square footage and the depth needed to hit R-38.
How we do it
We seal bypasses and penetrations first, then blow GreenFiber cellulose to the target depth, raking it level so the R-value is consistent wall to wall.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old, thin fiberglass batts that are compressed or stained, and you want a fast, affordable bump in coverage without removing everything.
What it costs in Burbank
Blown-in fiberglass over an existing attic floor typically costs $1,100 – $2,900 in Burbank, based on depth and attic size.
How we do it
We can blow loose-fill fiberglass directly over existing batts after checking for moisture and air leaks, bringing the whole attic to a uniform R-value in one visit.
What Blown In Insulation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Blown-in cellulose attic (full coverage) | $1,200 – $3,100 |
| Blown-in fiberglass attic (over existing) | $1,100 – $2,900 |
| Dense-pack wall cavity fill | $2,800 – $6,500 |
Will blown in insulation lower my Burbank energy bill?
Yes. Attic insulation upgrade in Burbank typically cuts cooling costs 10 – 25% by keeping valley heat from radiating through your ceiling all afternoon. Exact savings depend on existing R-value and your AC usage. Call (877) 521-4987 for a real estimate.
Can you blow insulation into my existing walls without tearing them open?
Yes, we dense-pack walls through small exterior holes that are patched afterward. This works well in Burbank bungalows with empty wall cavities. Call (877) 521-4987 to ask about your specific walls.
