Insulation in Burbank, CA
Spray foam insulation in Burbank solves a problem that matters more here than almost anywhere else in the Los Angeles basin: attic temperatures that climb past 150°F in July and August, radiating heat into living spaces all evening. Most Burbank homes were built in the 1940s through 1960s with wall cavities and attics that were never designed for this kind of sustained heat load. If your cooling bills keep climbing and your upstairs rooms never reach the thermostat setting, call Warmline Insulation Co. at (747) 837-5834 for a free estimate and a straight answer about what your home actually needs.
Why Burbank Homes Are Different
Burbank sits in a San Fernando Valley heat pocket where summer highs routinely exceed 105°F, and without the marine-layer cooling that moderates neighborhoods west of the Hollywood Hills, the city gets hit with 15 to 20 degrees more attic heat than areas just a few miles away. That means the insulation in a Burbank attic works harder than the same material in coastal Los Angeles, and old or compressed insulation fails faster here. Most of the housing stock in Magnolia Park and the Rancho District is post-WWII bungalows and ranch-style homes built with 2×4 stud framing, limited wall-cavity depth, and often no wall insulation at all. Original fiberglass batts in these attics have typically settled well below the Title 24 R-38 minimum, leaving large sections of ceiling with almost no thermal barrier. Critically, Burbank residents are served by Burbank Water and Power (BWP), a municipal utility with its own insulation rebate program entirely separate from SoCal Edison, a detail that trips up out-of-area contractors and gives local specialists an immediate credibility advantage. Seismic cripple-wall retrofit work, common on Burbank’s raised-foundation homes, also opens wall cavities that create a direct opportunity for simultaneous insulation upgrades.
Our Main Burbank Services
Two problems generate more calls to Warmline than any other in Burbank: under-insulated attics from the post-war building era, and damp, vented crawl spaces beneath raised foundations. Here’s what each involves in this city.
Attic Insulation in Burbank
Burbank attics routinely hit 130°F to 150°F in summer, and old fiberglass batts that have compressed to R-19 or less do almost nothing to stop that heat from pushing into living spaces. We remove or top up whatever is up there and bring the attic to current R-38 standards using blown-in fiberglass from Johns Manville or Knauf, then verify coverage with depth markers before we leave. Most jobs in Burbank are completed in a single visit, and the 90-Day Done Right Promise applies to every attic we insulate. For a full breakdown of this service, see Attic Insulation in Burbank.
Crawl Space Encapsulation & Vapor Barrier in Burbank
Raised foundations are standard across Burbank’s older neighborhoods, and the vented crawl spaces beneath them pull hot, moist outside air directly against the floor structure all summer. We seal vents, install a heavy-duty vapor barrier across the ground, and insulate the perimeter so the crawl space stops driving humidity into the home. Homeowners in the Rancho District regularly tell us the difference is noticeable within days. Learn more about options and local rebates on our Crawl Space Encapsulation & Vapor Barrier in Burbank page.

Spray Foam Insulation in Burbank
Closed-cell spray foam is the most effective single answer to Burbank’s sustained triple-digit summer heat, because it creates an air barrier and an R-value upgrade in one application. In 1940s and 1950s ranch homes with open attic rafter bays, spray foam applied to the roof deck can drop attic temperatures by 40 degrees or more, taking pressure off the HVAC system from the hottest part of the house down. Homeowners who have fought uneven room temperatures for years see the biggest change. Call (747) 837-5834 to ask us about a closed-cell roof deck application for your Burbank home.
Open-Cell Spray Foam
Signs you need it
Your Burbank home has interior noise transfer between rooms, or the attic floor has dense-packed insulation but no air sealing at the top plates.
What it costs in Burbank
Open-cell spray foam typically runs $1.50-$3.50 per board foot in Burbank, depending on depth and access.
How we do it
We mask the work area, spray the foam to the specified depth, let it cure, then trim and verify coverage with a depth gauge before cleanup.
Closed-Cell Spray Foam
Signs you need it
Your roof deck radiates heat into the attic all summer, and your second-floor rooms never cool down even after the AC runs for hours.
What it costs in Burbank
Closed-cell spray foam costs $2.00-$4.50 per board foot in Burbank, with roof deck applications at the higher end because of the added heat exposure.
How we do it
We apply closed-cell foam directly to the underside of the roof sheathing, creating a sealed, insulated barrier that turns the attic into conditioned space.
What Spray Foam Insulation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Open-cell spray foam (per board foot) | $1.50-$3.50 |
| Closed-cell spray foam (per board foot) | $2.00-$4.50 |
| Spray foam attic roof deck (full attic) | $4,500-$9,800 |
Is spray foam worth the cost in Burbank’s climate?
For homes with attic temperatures over 140°F in summer, closed-cell spray foam on the roof deck often cuts cooling costs by 20 to 30 percent, and the air-sealing benefit makes every other upgrade more effective.
Does spray foam work on Burbank’s older stud walls?
Yes. Injection or drill-and-fill spray foam compresses into 2×4 wall cavities cleanly, and it outperforms fiberglass because it fills the irregular gaps left by 70-year-old framing. Call (747) 837-5834 for an exact quote.
We work with Icynene and Demilec closed-cell and open-cell products. For a full description of our spray foam methods, visit our Spray Foam Insulation hub page.
Blown-In Insulation in Burbank
We blow fiberglass or cellulose over existing attic batts to bring Burbank’s post-war homes back up to current code, and the material cost is almost always lower than tearing out and replacing everything. Blown-in fiberglass at R-38 is the workhorse for the city’s flat and low-slope ranch roofs, because it fills completely around the odd framing and electrical junction boxes common in older attics. The job usually takes half a day.
Blown-In Cellulose
Signs you need it
Your attic batts are compressed and dusty, and you want a dense, recycled-material barrier that slows heat gain from Burbank’s hot roof deck.
What it costs in Burbank
Blown-in cellulose in Burbank runs $1.20-$2.80 per square foot, with GreenFiber as our standard product.
How we do it
We prep the attic, blow the cellulose to the specified depth, fluff it to reach the target R-value, and verify depth with markers.
Blown-In Fiberglass
Signs you need it
Your attic has old, settled batts that measure R-19 or less, and you want a stable, fire-resistant material that won’t compress over time.
What it costs in Burbank
Blown-in fiberglass in Burbank runs $1.10-$2.50 per square foot, using Johns Manville or Knauf material.
How we do it
We remove anything blocking air flow, install baffles at the eaves, and blow fiberglass to a consistent R-38 depth across the entire attic floor.
What Blown-In Insulation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Blown-in cellulose (per sq ft) | $1.20-$2.80 |
| Blown-in fiberglass (per sq ft) | $1.10-$2.50 |
| Blown-in top-up over existing batts | $900-$1,800 |
Can you blow insulation over my old attic batts?
In most Burbank attics, yes. We inspect for moisture or rodent damage first, then blow fiberglass directly over the existing batts to bring the total depth to R-38. Call (747) 837-5834 to schedule an inspection.
How thick should blown-in insulation be in Burbank?
R-38 fiberglass should sit at about 14 to 16 inches after settling. Most Burbank attics currently hold 4 to 8 inches, which is why cooling loads in this city run so high.
See the full range of blown-in options on our Blown-In Insulation hub page.
Radiant Barrier Installation in Burbank
A radiant barrier stapled to the underside of Burbank roof rafters reflects the heat that radiates from a 150°F roof deck back out through the roof, and it is one of the lowest-cost upgrades for a hot attic. In the San Fernando Valley heat pocket, a radiant barrier can drop attic temperatures by 15 to 25 degrees on the hottest afternoons, and it works alongside whatever insulation sits on the attic floor. For Burbank homes built in the 1940s and 1950s with minimal roof sheathing insulation, this is frequently the first upgrade we recommend.
Attic Radiant Barrier
Signs you need it
Your attic is 140°F or hotter on summer afternoons, and your AC runs almost continuously from mid-July through September.
What it costs in Burbank
Attic radiant barrier installation in Burbank runs $0.90-$2.00 per square foot of attic floor area.
How we do it
We staple a double-sided foil barrier to the underside of the roof rafters, keeping a 1-inch air gap for reflectivity, and trim around vents and framing.
Radiant Barrier Roof Deck
Signs you need it
Your roof sheathing gets too hot to touch in summer, and you want to stop heat at the source before it ever enters the attic air.
What it costs in Burbank
Roof deck radiant barrier runs $1.10-$2.40 per square foot in Burbank, including the air gap battens we install first.
How we do it
We attach battens to the roof deck, then staple the radiant barrier across them so the reflective face sits against the air gap.
What Radiant Barrier Installation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Attic floor-area radiant barrier (per sq ft) | $0.90-$2.00 |
| Roof deck radiant barrier (per sq ft) | $1.10-$2.40 |
| Radiant barrier + attic ventilation package | $2,200-$4,500 |
Does a radiant barrier replace attic insulation in Burbank?
No. A radiant barrier reflects radiant heat, but it does nothing for conductive or convective heat transfer. It works best when paired with R-38 attic insulation. Call (747) 837-5834 to discuss a combined package.
Will a radiant barrier damage my roof in Burbank’s heat?
No. When installed with the required air gap, a radiant barrier actually lowers the roof deck temperature slightly by reducing heat absorbed into the sheathing. Our 90-Day Done Right Promise covers every installation.
More details are on our Radiant Barrier Installation hub page.
Insulation Removal & Replacement in Burbank
Older Burbank homes harbor insulation that has been compromised by decades of heat, dust, and in many cases roof rats, which are common in the city’s mature tree canopy. When batts have compressed to R-11 or less, or when rodent contamination has made the attic a health hazard, removal and replacement is the only responsible fix. We do the full job in one visit and haul away everything we remove.
Attic Insulation Removal
Signs you need it
Your attic insulation is compressed, discolored, or visible from the ceiling plane, and your energy bills have climbed steadily over the last few summers.
What it costs in Burbank
Attic insulation removal in Burbank runs $1.00-$2.50 per square foot, including bagging and haul-away.
How we do it
We use commercial HEPA-filtered vacuums to extract the old insulation, bag it, and remove it from the attic through the access point.
Contaminated Insulation Removal
Signs you need it
You see rodent droppings, urine stains, or nesting material in the attic, or you smell a persistent musty odor near the ceiling or light fixtures.
What it costs in Burbank
Contaminated insulation removal in Burbank runs $1.50-$3.00 per square foot, with sanitizing included in the base removal price.
How we do it
We remove all contaminated material, sanitize the attic with an antimicrobial treatment, and prep the space for fresh insulation the same day.
What Insulation Removal & Replacement Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Attic insulation removal (per sq ft) | $1.00-$2.50 |
| Contaminated insulation removal (per sq ft) | $1.50-$3.00 |
| Full removal + R-38 replacement | $3,500-$7,500 |
Do I need to remove old insulation before adding new?
Not always. If the existing material is dry, uncompressed, and uncontaminated, we can often blow new insulation over it. We’ll tell you honestly which route makes sense after an inspection. Call (747) 837-5834 to book one.
How long does a full removal and replacement take in Burbank?
Most single-story Burbank homes are done in one day. Larger attics or heavy contamination may take a second day, but we’ll confirm the timeline before we start.
Our Insulation Removal & Replacement hub page covers the full process.
Attic Air Sealing in Burbank
Hot air from a Burbank attic pushes into living spaces through every unsealed top plate, can light, and duct boot, and no amount of insulation stops that convective heat transfer. Air sealing is the first step in any thermal upgrade in this city, because Burbank’s 105°F summer afternoons turn every tiny gap into a heat pathway. Homes in the Rancho District with original 1950s can lights and unsealed attic hatches typically leak 20 to 30 percent of their conditioned air.
Attic Floor Air Sealing
Signs you need it
Your upstairs rooms are 5 to 8 degrees warmer than the rest of the house, and you feel warm air near ceiling light fixtures or the attic hatch.
What it costs in Burbank
Attic floor air sealing in Burbank runs $0.80-$2.00 per square foot, depending on how many penetrations need treatment.
How we do it
We clear insulation from each penetration, seal the gaps with foam or caulk, then restore and re-level the insulation over the sealed floor.
Can Light & Duct Boot Sealing
Signs you need it
Your recessed lights feel warm to the touch, or you see dust streaks on the ceiling around can lights and supply registers.
What it costs in Burbank
Can light and duct boot sealing in Burbank runs $25-$60 per fixture depending on access and housing type.
How we do it
We install rated covers over non-IC can lights, seal duct boots with mastic and foam, and verify the seal with a smoke pencil.
What Attic Air Sealing Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Attic floor air sealing (per sq ft) | $0.80-$2.00 |
| Can light sealing (per fixture) | $25-$60 |
| Whole-attic air sealing package | $1,400-$3,200 |
Does air sealing really make a difference in Burbank?
Yes. When outdoor air is 105°F and your attic is 140°F, sealing the attic floor stops hot air from being pulled into the house every time the AC kicks on. Many Burbank homeowners notice a difference within a week.
Should I air seal before or after adding insulation?
Always before. Sealing the attic floor is impossible once new insulation covers the penetrations. We always seal first, then blow insulation. Call (747) 837-5834 to schedule a combined job.
See our Attic Air Sealing hub page for more on the process.
Wall Insulation in Burbank
Most Burbank homes built from the 1940s through the 1960s have 2×4 exterior walls with either no insulation or a thin layer that has settled to uselessness. In a city where afternoon heat soaks through sun-facing walls for six months of the year, retrofitting those cavities is often the single most effective comfort upgrade. Injection foam works especially well here because it fills the irregular cavities and old electrical penetrations common in post-war construction.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls feel warm to the touch in the late afternoon, and rooms along western and southern exposures never stay cool.
What it costs in Burbank
Drill and fill wall insulation in Burbank runs $3.50-$6.50 per square foot of wall area, including patching and paint-ready repairs.
How we do it
We drill small access holes through the siding or drywall, blow insulation into each stud cavity, then patch the holes to a smooth finish.
Injection Foam Wall Insulation
Signs you need it
Your walls have no insulation at all, and you want the highest R-value per inch available for a 2×4 cavity in Burbank’s heat.
What it costs in Burbank
Injection foam in Burbank runs $4.00-$7.00 per square foot of wall area, using slow-rise foam that fills every gap.
How we do it
We inject slow-rise foam through small ports into each cavity, monitoring the fill to ensure complete coverage without over-pressuring the walls.
What Wall Insulation Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Drill and fill wall insulation (per sq ft) | $3.50-$6.50 |
| Injection foam wall insulation (per sq ft) | $4.00-$7.00 |
| Full exterior wall retrofit (typical Burbank home) | $4,800-$9,500 |
Can you insulate walls from the outside without tearing out drywall?
Yes. We can drill through stucco or wood siding on the exterior, fill each cavity, and patch the holes. For many Burbank ranchers, exterior access is actually faster than interior work. Call (747) 837-5834 to discuss your home’s layout.
How much difference does wall insulation make in Burbank?
For homes with empty 2×4 wall cavities, filling them typically cuts wall heat gain by 40 to 60 percent. Rooms on the west and south sides are the ones that change the most.
Our Wall Insulation hub page explains every method in detail.
Attic Cleaning & Rodent Proofing in Burbank
Burbank’s mature street trees and warm attics create ideal conditions for roof rats, and most older homes in the city have at least one entry point around the roofline or venting. Rodent activity damages insulation, chews wiring, and leaves droppings that compromise indoor air quality. We clean everything out, sanitize the space, and seal every entry point so the problem doesn’t return.
Attic Cleanout
Signs you need it
You hear scratching or scurrying in the attic at dawn or dusk, or you see droppings and nesting material around the attic access.
What it costs in Burbank
Attic cleanout in Burbank runs $600-$1,500 depending on attic size and the amount of debris.
How we do it
We remove all contaminated insulation and debris, vacuum the entire attic, and haul everything away the same day.
Rodent Proofing & Exclusion
Signs you need it
You see gnaw marks on roof edges or vent screens, or you have had a rodent problem recur after a previous cleanup.
What it costs in Burbank
Rodent proofing and exclusion in Burbank runs $450-$1,200 for a typical single-story home, depending on how many entry points we find.
How we do it
We inspect the entire roofline and foundation, seal every gap and vent with steel mesh and foam, and document the work with photos.
What Attic Cleaning & Rodent Proofing Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Attic cleanout (typical Burbank attic) | $600-$1,500 |
| Rodent proofing & exclusion | $450-$1,200 |
| Full cleanout + sanitizing + exclusion + new insulation | $3,800-$8,200 |
Do I need to replace insulation after rodent removal in Burbank?
In most cases, yes. Rodents compress and contaminate insulation beyond salvage, and replacing it is the only way to restore thermal performance and air quality. We can quote the full package after an inspection.
How quickly can you respond to a rodent problem in Burbank?
We schedule Burbank attic cleanouts within 2 to 3 business days, and emergency cases can often be handled sooner. Call (747) 837-5834 and a live person will answer.
Our Attic Cleaning & Rodent Proofing hub page covers the full sequence.
Home Energy Audit in Burbank
A home energy audit is the diagnostic step that tells us exactly where your Burbank home is losing conditioned air, and it ensures you spend money on the fix that actually matters. In a city where BWP rebates are tied to verified performance, an audit also creates the documentation you need to claim every available incentive. We treat the audit as the starting point, not an upsell.
Blower Door Test
Signs you need it
Your energy bills are high but you are not sure where the leaks are, or you want a verified air-leakage number before and after air sealing work.
What it costs in Burbank
A blower door test in Burbank runs $250-$450 as part of a full audit.
How we do it
We mount the blower door in an exterior door frame, depressurize the house, and measure total air leakage in CFM at a standard pressure.
Thermal Imaging Inspection
Signs you need it
You have cold or hot spots in specific rooms, or you want visual proof of exactly where wall and ceiling insulation is missing or failed.
What it costs in Burbank
A thermal imaging inspection in Burbank runs $200-$400 when bundled with a full home energy audit.
How we do it
We scan every wall, ceiling, and floor with an infrared camera, documenting temperature anomalies that indicate missing insulation or air leaks.
What Home Energy Audit Costs in Burbank
| Item | Typical range in Burbank |
|---|---|
| Blower door test (standalone) | $250-$450 |
| Full home energy audit with thermal imaging | $450-$800 |
| Audit + duct leakage test package | $650-$1,100 |
Does BWP require an energy audit for insulation rebates?
Burbank Water and Power rebates for attic insulation are typically tied to verified R-value improvements, and an audit provides the documentation the program requires. We handle the paperwork for you. Call (747) 837-5834 to ask about your address.
How long does a home energy audit take in Burbank?
Most single-family Burbank homes take two to three hours, including the blower door test, thermal scan, and attic inspection. We send you the full report within 48 hours.
Our Home Energy Audit hub page explains what we measure and why it matters.

What Burbank Customers Say
"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"Radiant barrier stapled to the rafters plus new baffles at the soffits. Attic temperature dropped enough that the AC runs noticeably less in the afternoon. Crew was in and out in a day and left the garage cleaner than they found it."
- Sam Kessler"They did the energy audit first - blower door and thermal camera - and showed me exactly where the house was leaking before selling me anything. The fix ended up being air sealing plus a modest attic top-up, not the full replacement another company pushed."
- Grace Nakamura
