Demilec Attic Cleaning & Rodent Proofing in Burbank: What to Know First
Demilec attic cleaning and rodent proofing in Burbank typically runs $1,200 to $3,800 depending on attic size, contamination level, and how much exclusion work the structure needs. Most Demilec homes we service are completed in a single visit, usually within one full day. As an independent Demilec service provider, we handle the full scope: cleanout, sanitizing, rodent exclusion, and restoration of the insulation system around your existing Demilec foam or fiberglass.
If you own a Burbank home with Demilec insulation and you’ve heard scratching, smelled rodent urine in the attic, or found droppings near your HVAC ducts, this page is for you. Call (747) 837-5834 and a live person answers, 24/7, no voicemail maze.
How Demilec Products Fail - and How We Fix Them
- Heatlok HFO Pro spray foam with rodent tunneling. Rats and mice in Burbank attics burrow directly into open-cell and closed-cell foam, especially along soffit transitions and top plates. The foam’s density makes tunnels hard to spot from below. We excavate damaged foam, treat the void, and seal entry points before patching with compatible material.
- Heatlok HFO High Lift on older roof decks with delamination gaps. Burbank’s summer attic temperatures regularly exceed 140°F, and we see foam pulling away from older plywood where dust or moisture was present during original application. Rodents exploit those seams. We re-adhere or cut back delaminated sections, clean the cavity, and close the gap.
- Demilec Sealection 500 open-cell foam holding rat urine odor. Open-cell foam absorbs liquids, which is why a contaminated Sealection attic can smell for months after the rodents are gone. We remove saturated foam in affected zones rather than masking it, then re-apply fresh material after sanitizing the deck.
- Polar Foam series with surface nesting damage. Squirrels and rats tear away at the foam’s outer skin to create nesting depressions. We see this most often near gable vents and unsealed eaves in Burbank’s older Magnolia Park and Chandler Park homes. We trim back shredded foam, disinfect the surface, and install physical exclusion at the entry point.
- Demilec fiberglass batts (Demilec-branded) compressed by rodent traffic. Once rodents nest in batt insulation, they flatten it to nearly zero R-value in the affected lanes. We remove and replace compromised batts, then rodent-proof the perimeter so the new material stays intact.
Our Demilec Attic Cleaning & Rodent Proofing Process
- 1
Call and assessment. You call (747) 837-5834. We ask about the attic access, the age of the home, and what you’re hearing or smelling. Most Burbank attics we can diagnose with a 45-minute on-site inspection.
- 2
Attic inspection and entry-point mapping. Our tech walks the full attic, identifies rodent entry points, and documents the condition of your Demilec insulation. We note whether foam needs repair or removal and whether batts need replacement.
- 3
Cleanout and decontamination. We remove droppings, nesting debris, and contaminated insulation. Every surface gets treated with an EPA-registered sanitizer. We don’t just fog the space and call it done.
- 4
Exclusion and proofing. We seal every entry point we mapped: gable vents, soffit gaps, roof returns, plumbing penetrations. We use steel mesh, flashing, and foam-compatible sealants. This is the step that makes the fix permanent.
- 5
Insulation repair or replacement. Damaged Demilec foam gets cut back, patched, or re-sprayed. Ruined batts get replaced. We work with your existing material so you’re not paying to re-insulate the entire attic when only a section failed.
- 6
Final walkthrough and guarantee. You see before-and-after photos of the work. Every Demilec attic cleaning and rodent proofing job is backed by our 90-Day Done Right Promise: if it’s not done right, we make it right.
What Demilec Attic Cleaning & Rodent Proofing Costs in Burbank
Here’s honest pricing based on what we actually see in Burbank attics:
- Basic attic cleanout, no insulation replacement: $900 to $1,500. Small attic, moderate droppings, your Demilec insulation is salvageable.
- Cleanout plus sanitizing and deodorizing: $1,400 to $2,200. This is the most common scope for Burbank homes with rodent activity.
- Full cleanout, exclusion, and partial insulation replacement: $2,400 to $3,800. Larger attics, significant foam damage, or batts that can’t be saved.
- Whole-attic removal and re-insulation after heavy contamination: $4,000 to $8,500 depending on square footage and material (spray foam costs more than blown-in).
What moves the price: attic access (pull-down stairs vs. a scuttle hole), how much foam vs. batt you have, and how many entry points need sealing. We give upfront pricing before any work starts, and most jobs are completed in a single visit.

FAQs
Rodent damage is not covered by any manufacturer’s warranty, including Demilec’s. Our cleaning and exclusion work is designed to work around your existing insulation without creating new problems. As an independent Demilec service provider, we follow practices that don’t void your original installer’s workmanship coverage where it still applies.
We schedule most Demilec attic cleaning and rodent proofing jobs within 3 to 5 business days, and we can often accommodate same-week emergency appointments when a live rodent is in the attic or odor is entering the living space. Call (747) 837-5834 and a live person will give you the next available slot.
Cleaning and rodent proofing is almost always cheaper than full replacement, because most Demilec insulation can be salvaged if we get to it before the damage spreads. We’ll tell you honestly during the inspection whether your foam or batts are worth saving. We won’t sell you a full re-insulation if a targeted repair does the job.
Cleaning removes what you can see: droppings, nesting material, debris. Sanitizing treats what you can’t see: bacteria and odor sources embedded in the insulation and deck. We do both on every Demilec attic cleaning job, because skipping the sanitizing step is how homeowners end up with rodent smell returning weeks later.
Yes. We seal every entry point as part of the attic cleaning and rodent proofing scope. We handle the exclusion work ourselves so you’re not juggling two contractors. If the rodent population is active and large, we’ll coordinate with a licensed pest control partner for trapping or baiting, but the structural proofing is on us.
