Owens Corning Attic Cleaning & Rodent Proofing in Burbank: What to Know First
Independent Owens Corning attic cleaning and rodent proofing in Burbank typically runs $1,400 to $4,500 depending on attic size, contamination level, and whether insulation needs removal or can be restored in place. Most jobs are completed in a single visit, often within one to two days for heavily soiled attics. We are an independent Owens Corning service provider, not an authorized Owens Corning dealer, which means we call problems exactly as we see them and use the right materials regardless of brand politics. This page is for Burbank homeowners who own Owens Corning insulation, have rodents or years of accumulated filth in the attic, and want a crew that understands how Owens Corning products behave when they have been compromised. Call (747) 837-5834 and a live person answers, day or night.

How Owens Corning Products Fail - and How We Fix Them
Owens Corning makes good insulation. But good insulation does not survive rodents, roof leaks, or twenty years of neglect any better than the cheap stuff. Here is what we actually find in Burbank attics, especially in older homes around Magnolia Park and the hillside neighborhoods where raccoons and roof rats are a constant pressure.
- Owens Corning EcoTouch fiberglass batts become rodent condominiums. Rodents tunnel through the batts, shred the facing, and compress the fiberglass into dense, urine-soaked mats. The R-value collapses in those zones, and the smell does not leave on its own. We pull the compromised batts, sanitize the decking, and where the remaining batts are still viable, we fluff and re-lay them. Where they are not, we replace with fresh Owens Corning or equivalent R-value material.
- Atticat blown-in fiberglass settles and hides activity. Owens Corning Atticat settles over time, and rodents travel underneath it, leaving hidden runways and nests that never show on the surface. A visual inspection from the hatch misses everything. We rake back the material, expose the decking, and document the damage before we clean. Half of what we quote after a “clean” attic is contamination the previous contractor never saw because they never looked.
- Foam sheathing (Foamular, pink board) gets gnawed at the eaves. If your Burbank home has Owens Corning Foamular rigid foam at the roofline or gable ends, rats chew it for nesting material. The damage opens air gaps that pull hot attic air into the house in summer. We cut out the chewed sections, seal the gaps, and install new foam with metal flashing or hardware cloth backing to discourage a repeat.
- Thermafiber mineral wool holds odor differently than fiberglass. Owens Corning Thermafiber does not absorb moisture the way fiberglass does, but rodent urine still coats the fibers and the odor lingers in a way that surprises owners. You cannot just “air it out.” We apply an enzyme-based decontaminant specifically selected for mineral wool, then run HEPA air scrubbing during the job to pull particulate out of the space.
- Faced batts trap moisture against the drywall. Owens Corning kraft-faced batts installed with the facing downward or against drywall trap condensation in Burbank’s mild, damp winters. That moisture weakens the kraft, invites mold, and makes the attic smell like wet cardboard. When we find this during a cleaning, we correct the orientation or remove the facing entirely, then air-seal before re-insulating. This is a code issue and a comfort issue, and most homeowners only learn about it after a rodent job exposes it.
Our Owens Corning Attic Cleaning & Rodent Proofing Process
We do not guess, and we do not skip steps. Here is how a typical Owens Corning job goes from the first call to the final walkthrough.
- 1
Call and schedule. A live person answers, asks about the house, the age of the insulation, and what you have seen or smelled. We give you an arrival window and a real name to expect.
- 2
Attic inspection and scope. Neil Ashford or one of our background-checked, uniformed techs walks the attic. We photograph everything: entry points, nesting, droppings, insulation condition, air-sealing gaps. You get a written scope with prices before any work starts.
- 3
Debris removal and rodent exclusion. We remove all droppings, nesting material, food caches, and compromised insulation. Then we seal entry points with steel wool, hardware cloth, and foam sealant. Exclusion is the only way to make a cleaning stick. Clean an attic without sealing entry points, and you will repeat the job in six months.
- 4
Sanitizing and decontamination. We apply an enzyme-based cleaner to neutralize the urine and pheromones that attract new rodents. This is not a spray-and-hope step. We treat the decking, joists, and any ductwork that runs through the space. HEPA air scrubbing runs during the entire job, not after.
- 5
Insulation restoration or replacement. We save what is salvageable and replace what is not, matching your existing Owens Corning product where it still makes sense. This is where we decide whether the remaining batts or blown-in material will actually perform or just take up space.
- 6
Final test and walkthrough. We re-check every entry point, verify coverage and depth with a laser, and walk you through photos of the work. You get the 90-Day Done Right Promise in writing. If it is not right, we make it right.
What Owens Corning Attic Cleaning & Rodent Proofing Costs in Burbank
Honest numbers. No vague “affordable” talk.
- Basic attic cleaning, no rodents, existing insulation stays: $1,400 to $2,200. This covers debris removal, HEPA vacuuming, and sanitizing for a typical 1,200 to 1,800 sq ft Burbank attic.
- Full rodent decontamination, insulation removal, and exclusion: $2,800 to $4,500. You are paying for labor, enzyme treatment, HEPA air scrubbing, waste disposal, and sealing every entry point. The insulation replacement is additional.
- Insulation replacement after cleanup: $1.50 to $3.50 per square foot installed, depending on material (fiberglass batts, blown-in, or mineral wool) and depth required for Burbank’s climate zone.
- Air sealing added to the job: $600 to $1,200 for a typical attic. This is the single best return on investment in the whole scope, and we recommend it on every rodent job because the animals have exposed every leak.
What moves the price: attic size, how long the rodents have been active, whether ductwork needs sanitizing, and whether the decking needs structural repair. Call (747) 837-5834 for a free estimate. Upfront pricing, no surprises, and most jobs are done in a single visit.

We have been in business since 2011, and a lot of our Burbank calls are from people who had a handyman “clean” their attic and then called us when the smell came back.

Our techs know Owens Corning products because we install and remove them every week.

Good insulation shouldn’t be something you think about - that means it’s working.
FAQs
Most basic attic cleaning jobs are completed in a single day. Full rodent decontamination with insulation removal and exclusion typically takes one to two days depending on attic size and contamination level. Call (747) 837-5834 and we will give you a straight answer based on your attic’s square footage.
No. Owens Corning insulation warranties cover manufacturing defects, not cleaning or rodent damage. In fact, leaving rodent contamination in place accelerates degradation of the material, which no warranty covers regardless. The cleaning itself does not affect the warranty on any material we do not remove.
Cleaning is almost always cheaper if the insulation is intact, dry, and has not been tunneled through by rodents. If the material is compressed, saturated with urine, or shredded into mats, replacement is the better financial move because “cleaned” fiberglass with destroyed structure does not insulate. We will tell you which applies to your attic before we start, with photos to back it up.
We install Owens Corning when it is the right product for the job, along with other quality brands like Rockwool, CertainTeed, Johns Manville, and GreenFiber. Owens Corning does not make repair parts for insulation the way an HVAC manufacturer makes compressors. There is no “OEM” attic insulation in the way you may be thinking. What matters is R-value, fire rating, and proper installation. We spec the right material for your attic, not the one with the best marketing.
We run emergency response for rodent infestations and roof leaks that compromise attic insulation. A live person answers at (747) 837-5834, and we dispatch a technician to Burbank as quickly as the schedule allows, often same day. Estimates are free.
