How Demilec Products Fail - and How We Fix Them

We’ve pulled apart enough Demilec installations across Burbank to know exactly what goes wrong. Here are the five failure patterns we see most often:

• Heatlok HFO shrinkage at the rim joist. Heatlok HFO is Demilec’s closed-cell workhorse, but in Burbank’s older hillside and Magnolia Park homes, we regularly find it pulling away from rim joists where the wood framing was never cleaned properly before application. The foam looks fine from the living space, but cold air sneaks through the gap all winter. Our fix is cutting back the lifted edge, treating the substrate, and re-foaming the seam rather than demolishing the whole band.
• Sealection 500 open-cell density issues in attic rooflines. Sealection 500 is a half-pound open-cell foam that performs well until an installer shoots it too cold or too fast. The symptom is a crumbly, almost brittle texture instead of a resilient sponge. In Burbank attics, we see this on roof decks where the substrate sat under 140-degree shingles before application. We test density with a core sample and remove the underperforming section before re-spraying at the correct temperature.
• Heatlok Soya off-gassing complaints shortly after install. Heatlok Soya, Demilec’s soy-based line, is popular with Burbank owners who want a greener product, but some report a lingering odor for weeks after installation, especially in tight attic spaces with poor ventilation. The cause is usually an off-ratio mix at the gun, not the product itself. We flush the line, verify the A/B ratio with a test patch, and re-spray the affected area. The odor clears once the chemistry is correct.
• Polar Flash lift gaps on garage ceiling assemblies. Polar Flash is Demilec’s answer for air-sealing garage ceilings and bonus rooms, but in Burbank homes built before 1980, the old lath and plaster doesn’t always bond with the foam. Homeowners notice foam pulling away around recessed can lights. We remove the loose sections, prime the surface, and re-apply with a slower-rising formulation so the foam grips instead of fighting the substrate.
• GacoOnePass coating delamination on exposed foam roofs. On flat-roof Burbank additions where Demilec foam is left exposed to direct sun, the protective GacoOnePass coating sometimes delaminates if it was applied over dirty or damp foam. UV then breaks down the underlying foam within two summers. We strip the failed coating, sand the foam surface, and recoat with a properly prepped base layer. This is one of the most common Demilec issues we see in Burbank’s sunnier south-facing homes.

Key Takeaways

• Most Demilec spray foam failures in Burbank come from installation errors, not product defects.
• We diagnose first, then repair only what’s failing - no unnecessary full removal.
• Every Demilec repair we complete is backed by the 90-Day Done Right Promise.

Our Demilec Spray Foam Insulation Process

Here’s exactly what happens when you call us about Demilec spray foam insulation in Burbank:

1. 1
   Call and talk to a live person. You call (747) 837-5834 and describe what you’re seeing. We ask about the age of the home, where the foam is, and whether you’ve noticed drafts, dampness, or rising utility bills. You get a real conversation, not a voicemail.
2. 2
   We inspect the existing installation. A background-checked, uniformed technician arrives and examines the Demilec foam in place. We check for shrinkage, density inconsistencies, odor, and coating failures. We also look at the surrounding air-sealing because in Burbank’s older homes, the foam is rarely the whole story.
3. 3
   We make an OEM-vs-aftermarket parts decision. For Demilec-specific repairs, we source Demilec-compatible foam and coatings when the warranty is still active or when the homeowner wants exact brand continuity. When the warranty has expired, we may recommend a quality aftermarket equivalent that performs identically for less money. We’ll tell you the trade-off honestly.
4. 4
   We complete the repair in one visit. Most Demilec spray foam jobs, from rim joist repairs to full attic roof decks, are done in a single trip. We mask off the work area, apply the foam at the correct temperature and ratio, and clean up before we leave.
5. 5
   We test and document. We check the foam’s adhesion, density, and coverage before we call the job done. You get a written summary of what we found and what we did.
6. 6
   The 90-Day Done Right Promise covers everything. If anything isn’t right within 90 days, we make it right. Neil Ashford built this company on that standard, and it applies to every Demilec job we take.

What Demilec Spray Foam Insulation Costs in Burbank

Demilec spray foam insulation costs in Burbank depend on the scope, the product line, and whether we’re repairing or doing a fresh installation. Here’s what we typically see:

• Rim joist spray foam (Heatlok HFO or equivalent): $1,200 to $2,800 for a typical Burbank crawl space or basement band.
• Attic roof deck with Sealection 500 (open-cell): $3,500 to $7,500 for a standard 1,500 to 2,000 square foot attic.
• Garage ceiling spray foam (Polar Flash): $900 to $2,200 depending on square footage and access.
• Small repair or section re-spray: $450 to $1,500 for localized shrinkage, delamination, or odor correction.

What moves the price is access (crawl spaces and tight attics cost more in labor), the condition of the substrate (old plaster, dirty framing, or previous failed coatings need prep), and whether we’re using open-cell or closed-cell foam. You’ll get upfront pricing before any work begins, and most jobs are completed in a single visit. Call (747) 837-5834 for a free estimate, and ask about the $50 Off Any Repair Over $250 or the permanent 5% Senior & Veteran discount if either applies.

Why Burbank Homeowners Call Warmline Insulation Co. for Demilec Work

We’ve been serving Burbank since 2011, which means we’ve watched this city’s housing stock change and we know exactly how Demilec foam behaves in homes from the 1940s bungalows near Chandler Boulevard to the newer builds up in the Verdugo foothills. Our technicians understand Demilec’s product lines because we’ve worked with them for over a decade, not because we took a weekend training course. We’re also a full-spectrum insulation contractor, so if the real problem turns out to be a failed radiant barrier or a vent that bypasses the foam entirely, we fix the actual issue. And while Demilec is a product line we trust, we also service installations from other brands, including Reflectix, so we’re never trying to force a product you don’t need. When you call us, a live person answers. When we finish, the job is right, or we make it right within 90 days. Neil Ashford started Warmline Insulation Co. with that promise, and it’s the same one we make on every Demilec job in Burbank.
