Demilec Attic Cleaning & Rodent Proofing in Burbank: What to Know First
We provide independent Demilec attic cleaning and rodent proofing in Burbank, typically completing most jobs in one to two days with a written price before any work starts. Most Demilec attic restoration projects in Burbank run between $2,800 and $5,400 depending on contamination level, accessible square footage, and whether the spray foam needs partial removal to reach rodent pathways. This page is for homeowners whose Demilec-insulated attic has rodent damage, odor issues, or compromised foam that needs proper cleaning and exclusion work - call (213) 816-1699 for a free estimate with a written scope.
How Demilec Products Fail - and How We Fix Them
- Demilec SEALECTION 500 open-cell foam - Rodents tunnel through the soft, low-density structure (approximately 0.5 lb/ft³) and nest against warm top plates in Burbank’s winter temperature swings. We remove contaminated sections, seal entry points with galvanized steel flashing and copper mesh, then reinstall with matching density foam after the exclusion barrier is proven.
- Demilec HEATLOK Soya closed-cell foam - The rigid surface cracks when rodents gnaw repeatedly, creating hidden air leaks that blower-door tests catch even when visual inspection looks intact. We map the damage with thermal imaging, cut out compromised sections, and restore the air barrier before any new foam goes in.
- Demilec HEATLOK XT high-R foam in rafter bays - Urine saturation degrades the foam-to-wood bond in Burbank’s summer attic temperatures that regularly exceed 140°F. The foam delaminates and sags, creating voids. We remove the saturated material, treat the substrate with enzymatic cleaner, and reinstall only after moisture readings confirm the deck is dry.
- Demilec SEALECTION Agribalance - The bio-based content attracts specific pests when organic oils surface after UV exposure through unsealed gaps. We see this in Burbank’s older Magnolia Park homes with original gable vents. We clean the degraded surface, seal the light leaks, and apply a pest-resistant coating where code allows.
- Demilec foam around recessed can lights and chimney chases - These are the first areas rodents compromise because they’re pre-cut penetrations with ready-made highways. We remove the contaminated foam, install proper fire-rated covers and exclusion hardware cloth, then re-foam with Demilec-compatible product that maintains the original R-value and fire rating.
Our Demilec Attic Cleaning & Rodent Proofing Process

- 1
Written price and scope first. We inspect the attic, identify the Demilec product line and condition, and deliver a flat price with written warranty before any work starts - Haven Standard Clause 1.
- 2
Documented photo record and thermal scan. We photograph every contaminated area and run a thermal scan to find hidden voids in the foam that rodents have compromised but visual inspection misses.
- 3
Controlled removal of contaminated Demilec foam. We cut out only what’s damaged, bag it for proper disposal, and protect the remaining intact foam with barriers - never tear out healthy material to pad the invoice.
- 4
Enzymatic decontamination and drying verification. We treat wood substrates with enzyme cleaners that break down organic matter, then verify moisture content with a pinless meter before any new material touches the deck.
- 5
Rodent proofing and exclusion. We seal all entry points with galvanized steel, copper mesh, and concrete where needed - not spray foam alone, which rodents chew through in 48 hours.
- 6
Restoration and final documentation. We reinstall matching Demilec-compatible foam where required, deliver updated photos, and provide the written completion record with our 365-Day Done Right Promise.

What moves the price: square footage, how many Demilec foam layers must come out, whether the HVAC ducting in the attic was compromised, and if the electrical runs need an electrician partner. We also service Reflectix radiant barrier systems when they’re part of the same attic assembly.

Why Burbank Homeowners Call Topside Attic Insulation Burbank for Demilec Work

We’ve been working Burbank attics, including the ranch-style homes in Magnolia Park, long enough to know where the thermal bypasses hide in a 1960s rafter bay and how Demilec foam behaves in our specific climate. The 365-Day Done Right Promise covers every job, backed by a written scope and warranty delivered before anyone lifts a tool. Our technicians are background-checked and uniformed, and a live person answers calls 24/7 - no voicemail loops. When Demilec parts are backordered, we source quality aftermarket equivalents that maintain the thermal and fire performance specifications, and we document the substitution in writing. The R-value is what the label says. The performance is what the blower-door test says. We care about the second number.
FAQs
No, professional cleaning and rodent proofing by an independent service provider does not void Demilec’s material warranty, though damage caused by rodents or improper removal technique is not covered by Demilec. We document our removal methods with photos so any future claim has a clear record of what was done and how. Call (213) 816-1699 if you need help understanding your specific warranty terms - estimates are free.
Most Demilec attic cleanouts and rodent proofing jobs in Burbank take one to two days; heavy contamination with full foam replacement can extend to three days. We don’t rush drying time - enzyme-treated wood must read below 15% moisture before new foam goes in, or the bond fails within two years. Call (213) 816-1699 to schedule - a live person answers 24/7.
Repair is viable when less than 30% of the foam is compromised and the remaining material passes adhesion and density testing; replacement is necessary when urine saturation has degraded the foam-to-substrate bond or when rodents have created interconnected tunnel networks. We test and photograph the decision criteria so you see what we see. Call (213) 816-1699 for a free assessment with written recommendation.
We install Demilec-compatible open-cell and closed-cell foams that match the thermal performance of SEALECTION 500, HEATLOK Soya, HEATLOK XT, and Agribalance lines; exact color match varies by batch age and UV exposure. We specify the installed R-value, density, and air permeance in writing so the performance is documented regardless of visual match. Call (213) 816-1699 to discuss your specific product line - estimates are free.
We typically schedule inspections within 24 to 48 hours for Burbank properties, with same-day availability for active infestations where rodents are accessing living spaces. Emergency temporary exclusion can be performed immediately while the full restoration scope is developed. A live person answers (213) 816-1699 24/7 - no callback windows measured in business days.
