Demilec Insulation Removal & Replacement in Burbank: What to Know First
We provide independent Demilec insulation removal and replacement in Burbank, typically completing most jobs in one to two days depending on contamination level and attic access. Most Demilec removal and replacement projects in Burbank homes run between $2,800 and $6,400 for a standard 1,200-square-foot attic, with written pricing delivered before any work starts. This page is for homeowners who have Demilec open-cell or closed-cell spray foam in their attic or walls and are dealing with off-gassing, moisture trapping, or rodent contamination that requires full removal and replacement with a better-suited material. If you’re seeing sagging foam, persistent chemical odors, or water stains on drywall beneath insulated cavities, we can diagnose it and give you a written price. Call (213) 816-1699 - a live person answers, 24/7.
How Demilec Products Fail - and How We Fix Them
- Demilec Heatlok HFO High Lift off-gassing in Burbank’s heat. The HFO blowing agent in this closed-cell series can produce a sweet, chemical odor that intensifies when attic temperatures climb past 140°F, which happens regularly in Burbank’s Magnolia Park and Rancho Adjacent neighborhoods from June through October. We remove the affected Heatlok HFO completely and replace it with a mineral wool or fiberglass system that doesn’t off-gas at temperature, documenting pre- and post-removal air quality with photo evidence.
- Demilec Sealection 500 moisture trapping in older Burbank roof assemblies. This open-cell foam is vapor-permeable, which sounds good until it’s sprayed against original 1960s roof decking without a proper vent channel - a common shortcut we see in Burbank ranch remodels. The foam wicks roof leaks inward instead of letting them show, rotting the sheathing from the inside. We remove the Sealection 500, repair or replace damaged decking, install proper vent baffles, then replace with a vented assembly that actually dries.
- Demilec Heatlok Soy 200 degradation from rodent activity. Soy-based content in this closed-cell line makes it attractive to nesting rodents; we’ve pulled Heatlok Soy 200 from Burbank attics where squirrels have tunneled straight through it, leaving compressive voids and biohazard contamination. Full removal is non-negotiable - we bag it as contaminated insulation, sanitize the substrate, and replace with a rodent-resistant material backed by our 365-Day Done Right Promise.
- Demilec Agribalance shrinkage at top plates and rim joists. This open-cell formula can shrink 3-5% as it cures, pulling away from framing members and creating thermal bypasses - air pathways that bypass the insulation entirely. In Burbank’s 1970s tract homes near the airport flight path, we’ve found Agribalance gaps wide enough to slide a putty knife through. We remove the shrunken material, seal every top plate and penetration with acoustic sealant and rigid foam, then install a replacement system that maintains contact.
- Demilec Heatlok XT improper density in retrofit applications. Specified at 2.0 lbs/ft³ for closed-cell performance, we’ve encountered Burbank jobs where previous installers sprayed Heatlok XT too thin or at variable density, creating a vapor barrier that doesn’t actually block vapor and an R-value that doesn’t match the label. We density-test suspect areas during removal, strip it all if it’s inconsistent, and replace with a material whose performance we can verify with a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing.
Our Demilec Insulation Removal & Replacement Process
- 1
Call and scheduling. A live person answers (213) 816-1699 24/7. We book a site visit, usually within 48 hours for Burbank addresses.
- 2
Attic inspection and contamination assessment. We identify your Demilec product line by visual inspection and density testing where needed. We document rodent damage, moisture staining, and off-gassing severity with photos you’ll receive in your record.
- 3
Written price before any work starts. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
- 4
Removal and substrate remediation. We mechanically remove the Demilec foam, bag contaminated material per local disposal requirements, and treat the substrate for odors, mold, or rodent waste. This is where most contractors cut corners; we don’t.
- 5
Air sealing and replacement installation. Every penetration, top plate, and can light gets sealed before new insulation goes in. The R-value is what the label says. The performance is what the blower-door test says. We care about the second number.
- 6
Documentation and sign-off. You receive a Documented Photo Record, depth-and-coverage report, and where applicable, before-and-after blower-door readings. The 365-Day Done Right Promise begins at sign-off.

These are real Burbank numbers based on jobs we’ve completed in neighborhoods from Magnolia Park to the hillside homes near Verdugo Mountains. Your exact price depends on what we find when we look. Call (213) 816-1699 for a free estimate - written pricing delivered before any work starts, always.
Why Burbank Homeowners Call Topside Attic Insulation Burbank for Demilec Work
We’ve been working Burbank attics since 2016, and Wes Okafor has spent the better part of two decades applying trade fundamentals he learned at Kennedy-King College across California homes. We know where Demilec was specified correctly and where it was installed as a one-size-fits-all solution that didn’t fit Burbank’s climate or your particular roof assembly. As an independent Demilec service provider, we have no brand loyalty forcing us to reinstall a product that failed you - we also work with Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, and GreenFiber, plus Reflectix for radiant barrier applications where they make sense. Every job gets a named technician, a text when they’re en route, and documentation you can actually use. The 365-Day Done Right Promise is in writing before we start. That’s Haven Standard.
FAQs
Demilec’s product warranty covers defects in material itself, not installation errors or environmental damage - and it doesn’t prevent you from hiring an independent contractor for removal. We document the foam’s condition during removal with photos, so if there was a material defect, you have evidence for a claim. Call (213) 816-1699 and we’ll review your original paperwork with you at no charge.
Yes - and often improve it. Demilec closed-cell runs about R-6.5 per inch; we can achieve equivalent or better thermal performance with mineral wool or high-density fiberglass at competitive thickness, plus superior moisture management and no off-gassing. The blower-door test confirms the real-world result, not just the labeled R-value.
Most residential jobs finish in one to two days. If you’re dealing with active rodent contamination or extensive moisture damage, remediation adds a day. We don’t rush the drying or sanitizing phase - Haven Standard requires the substrate to be clean before new insulation goes in. Call (213) 816-1699 for scheduling; we typically book within 48 hours.
Spot repairs on spray foam rarely work well - the new foam doesn’t bond chemically to cured Demilec, creating delamination risks and thermal gaps. In our experience across Burbank homes, partial removal almost always becomes full removal within two years. We recommend doing it once, correctly, with a material suited to your specific assembly. We’ll show you both options in writing so you can decide.
We source materials from multiple suppliers including Demilec, but as an independent contractor, we have no obligation to reinstall Demilec if another product better serves your home. We explain the trade-offs - OEM compatibility, performance characteristics, long-term durability - and you choose. The written scope specifies exactly what goes in before anyone starts.
