Demilec Wall Insulation in Burbank: What to Know First
We provide independent Demilec wall insulation service in Burbank, typically turning residential jobs around in one to two days from the initial assessment. Most Demilec injection foam and drill-and-fill wall jobs in Burbank homes run between $2,800 and $5,400 depending on wall square footage, existing cavity conditions, and whether we need to address settled or degraded foam first. We are not affiliated with or authorized by Demilec - we are an independent service provider who works on what Burbank homeowners actually have in their walls.
This page is for owners of Demilec-insulated homes in Burbank, especially those in Magnolia Park, the hillside streets above Verdugo Mountains, and the ranch-style tracts near the studios where Demilec open-cell and closed-cell products were specified during 2010s energy retrofits. If your walls are underperforming, drafty, or were insulated with Demilec foam that has degraded, call (213) 816-1699. We answer live, 24/7.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO High Lift shrinkage in Burbank’s temperature swings. The HFO blowing agent in newer Heatlok formulations can contract more than legacy HFC-blown foam when Burbank’s 105°F August afternoons crash into 55°F same-night lows. We see this as gaps between stud bays and foam, visible with thermal imaging. Our fix: remove the degraded section, re-establish the air barrier with targeted injection, and verify with blower-door subtraction testing - a zone-by-zone pressurization reading that isolates the wall cavity from the rest of the envelope.
- Demilec SEALECTION 500 water absorption in north-facing Burbank walls. SEALECTION 500 is an open-cell water-blown foam. In Burbank homes where winter storms drive rain against unflashed or poorly caulked stucco, we’ve pulled samples showing 15-20% moisture content by weight - well above the 12% threshold where mold risk becomes real. We don’t just dry and patch. We cut back to sound substrate, address the water entry path, then reinstall with a closed-cell alternative or a hybrid system depending on the cavity depth.
- Demilec Agribalance settling in drill-and-fill retrofits. Agribalance, the soy-based open-cell line, was marketed heavily to green builders in the mid-2010s. In Burbank’s older 2×4 walls with irregular stud spacing - common in the 1950s-60s ranch stock near Magnolia Park - the lower density can settle 10-15% over five to seven years, leaving a thermal bypass at the top plate. We diagnose this with borescope inspection and fix it with dense-pack cellulose top-off or re-injection, depending on whether the original foam is salvageable.
- Demilec Heatlok XT off-gassing and odor complaints. Heatlok XT, the closed-cell product with a high bio-content claim, can emit trace amines if the A-B component ratio drifts during original installation. Burbank homeowners in tightly sealed newer construction - the in-fill condos near downtown, especially - notice it first because there’s less natural dilution. We don’t mask odors. We identify the affected bays, remove the foam mechanically, ventilate the cavity to below 500 µg/m³ total VOC, then reinstall with a specified alternative, typically Johns Manville Corbond or a Knauf closed-cell equivalent.
- Demilec foam-to-drywall adhesion failure from Burbank’s clay-heavy soil movement. Burbank sits on a mix of alluvial fan deposits and compacted clay that shifts seasonally. That movement transmits through framing, and we’ve seen Demilec closed-cell foam delaminate from drywall or sheathing in homes within two blocks of the Verdugo fault trace. The foam itself is intact, but the air seal is broken. We repair by cutting access, re-bonding with compatible adhesive where possible, or transitioning to a mechanically secured insulation system where the structure won’t stabilize.
Our Demilec Wall Insulation Process
- 1
Call and scheduling. A live person answers. We book a 90-minute assessment window, send a text when our technician is en route, and name the technician you’ll meet. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
- 2
On-site diagnostic. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. For Demilec jobs, we follow with thermal imaging and targeted borescope inspection of suspect wall cavities. Wes Okafor and his crew have worked enough Burbank attics and walls to know where Demilec foam from the 2010s retrofit boom tends to hide its failures.
- 3
Written scope and price. Before any work starts, you receive a flat price, written scope, and written warranty. Haven Standard Clause 1, no exceptions. If you have a competing estimate, we provide a Free Second Opinion - we’ll read it with you line by line.
- 4
Air sealing first, then insulation. We seal every penetration, top plate gap, and electrical box before adding or replacing insulation. The R-value is what the label says. The performance is what the blower-door test says. We care about the second number.
- 5
Installation with documentation. For Demilec replacement, we select from our multi-brand inventory - Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - based on what your wall cavity and budget actually need, not what we have a preference for. No proprietary lock-in.
- 6
Post-work verification and closeout. We run a second blower-door test, provide before-and-after numbers, deliver a Documented Photo Record of the completed work, and leave you with the written warranty. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
Before
AfterWhat Demilec Wall Insulation Costs in Burbank
Most Demilec wall insulation jobs in Burbank fall into these ranges:
| Job Type | Typical Range | What Moves the Price |
|---|---|---|
| Drill-and-fill injection foam (single-story, 1,200 sq ft walls) | $2,800 - $4,200 | Cavity access, existing foam removal, stucco repair |
| Demilec removal + replacement with closed-cell | $4,000 - $6,800 | Extent of degradation, disposal fees, sheathing repair |
| Interior wall soundproofing (open-cell Demilec or Rockwool) | $3,200 - $5,400 | Number of walls, finish repair, STC rating target |
| Exterior wall insulation (access from outside) | $3,800 - $6,200 | Siding type, scaffolding, weather barrier replacement |
Factors that push toward the high end: homes with original Demilec foam requiring full cavity evacuation, stucco-sided homes needing access hole patching, and multi-story jobs where interior finish repair is extensive. We don’t guess at your price. Every estimate is free, written, and delivered before any work starts. Call (213) 816-1699 to schedule.

We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. In Burbank specifically, we know the building stock: the 1960s ranches with their odd stud spacing, the hillside homes with their thermal bridging at cantilevers, the studio-area condos built tight enough that any insulation off-gassing becomes immediate and obvious.
Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7 - no voicemail loops, no callback windows measured in business days. We carry Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, plus Reflectix for radiant barrier applications where that’s the right supplement to wall insulation. If your Demilec product can’t be salvaged, we have alternatives that match your performance target without locking you into a single brand.
The 365-Day Done Right Promise backs every job. The before-and-after blower-door numbers prove it.
FAQs
No - Demilec’s original installation warranty was with the contractor who applied the foam, and those terms typically ran 1-5 years from application. As an independent Demilec service provider, we don’t extend Demilec’s original warranty, but our 365-Day Done Right Promise and written scope provide coverage for the work we perform. If your original installer is gone or unresponsive, which we see frequently with 2010s Burbank retrofits, our documentation gives you a clear record for any future claim or resale disclosure. Call (213) 816-1699 and we’ll review what you have.
We can source current Demilec formulations through our supplier network, but we don’t default to them. For many Burbank wall cavities, especially the 2×4 construction common in Magnolia Park, a Knauf or Johns Manville closed-cell product at a higher density-per-inch delivers better R-value in the available depth. We specify based on your cavity, your budget, and the blower-door target, not on brand loyalty. You’ll see the alternatives and the price difference in your written scope before we start.
Repair is viable when the foam is intact but the air seal is compromised at discrete points - top plates, electrical boxes, or settled areas under 20% of the cavity. Replacement is necessary when we find moisture damage, significant shrinkage gaps, or off-gassing that won’t ventilate below acceptable thresholds. We determine this with borescope inspection and cavity moisture readings, not guesswork. The assessment is free, and we’ll show you the images. Call (213) 816-1699 to book.
Most residential Demilec wall jobs in Burbank are completed in one to two working days from our arrival. Single-story drill-and-fill jobs with no removal required often finish same-day. Jobs requiring full cavity evacuation, sheathing repair, or exterior access with stucco patching typically run two days. We don’t schedule faster than we can execute correctly - the written scope defines the timeline, and we hit it. Call (213) 816-1699 for availability.
You receive four items: a written invoice with line-item breakdown, a Documented Photo Record of the completed work, your written warranty under the 365-Day Done Right Promise, and on applicable jobs, before-and-after blower-door readings showing the actual air-leakage reduction. This is standard on every job, not available on request. We believe a customer who understands what they paid for is easier to work with than one who just trusts the brochure.
