This page is for Burbank homeowners who have Johns Manville attic insulation - whether formaldehyde-free batts, Climate Pro blown-in fiberglass, or older Spintex rolls - and are dealing with rodent damage, soiled insulation, or the telltale ammonia smell that drifts through ceiling penetrations on hot San Fernando Valley afternoons. We are an independent Johns Manville service provider, not affiliated with or authorized by the manufacturer.

How Johns Manville Products Fail - and How We Fix Them

• Climate Pro blown-in fiberglass packs down under rodent traffic. The loose-fill structure that gives Climate Pro its coverage rating collapses where rats and squirrels establish runways, creating bare spots that read as cold zones on a thermal camera. We remove the compacted material, sanitize the substrate, and reinstall to labeled depth with new Climate Pro or an equivalent loose-fill - never blowing fresh product over soiled pack.
• Formaldehyde-free batts (FF batts) wick urine and hold odor. The bonded glass mat in Johns Manville’s formaldehyde-free line doesn’t degrade from moisture, but the binder chemistry traps ammonia compounds from rodent urine. Homeowners in Burbank’s Magnolia Park neighborhood often call us when the HVAC kicks on and the return air pulls attic smell through bypasses. We pull the batts, HEPA-vacuum the framing, apply an enzyme treatment, and replace with fresh product.
• Spintex rolls in pre-1990s Burbank ranches delaminate after prolonged nesting. The foil or kraft facing separates from the fiberglass core when rodents compress and tunnel through it for thermal cover. We see this in the older ranch-style homes near Verdugo Avenue where the original Spintex is still in place. The fix is full removal - partial replacement leaves delaminated pockets that vent moisture into the ceiling.
• Johns Manville attic insulation with blown-in over batts creates layered contamination zones. When a previous contractor added loose-fill over existing batts without air sealing first, rodents nest between the layers where the temperature gradient is most stable. Our crew removes both layers, seals all top plates and penetrations, then reinstalls as a single system with documented depth and coverage.
• Kraft-faced batts near Burbank’s vented soffits collect rodent debris at the eaves. The facing paper provides a chewable edge that squirrels favor for nesting material, and the resulting gaps compromise the pressure boundary. We replace kraft-faced product with unfaced batts or loose-fill after sealing the eaves with galvanized mesh, which rodents cannot penetrate.

Our Johns Manville Attic Cleaning & Rodent Proofing Process

1. 1
   Written price and scope before arrival. Under Haven Standard Clause 1, you receive a flat price, written scope, and written warranty before anyone lifts a tool - no “call for a quote” runaround.
2. 2
   Attic inspection with photo documentation. We photograph contamination extent, insulation depth measurements, and active rodent entry points. You get these photos in your Documented Photo Record.
3. 3
   Insulation removal and HEPA containment. Johns Manville product is bagged and removed through a sealed chute; we do not push contaminated material into corners or bury it under new layers.
4. 4
   Sanitizing, enzyme treatment, and structural repair. Substrate is treated for bacteria and odor; chewed wires, soiled drywall, and compromised ductwork are flagged for repair before reinstallation.
5. 5
   Rodent proofing and exclusion. All entry points larger than 1/4 inch are sealed with galvanized steel mesh, concrete, or copper wool - materials rodents cannot chew through. We map every sealed point on your record.
6. 6
   Air sealing, then fresh Johns Manville or equivalent insulation. Top plates, can lights, plumbing stacks, and wire penetrations are sealed first. Then we install new insulation to labeled R-value with depth-and-coverage documentation. Where applicable, we run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope was losing before and after.

What Johns Manville Attic Cleaning & Rodent Proofing Costs in Burbank

What moves the price: attic square footage, insulation depth to remove, contamination severity, accessibility (truss vs. stick-framed), and whether the previous install was layered or single-system. We also service Reflectix radiant barrier systems when those are present and damaged. Every estimate includes a Free Second Opinion on any competing written quote - bring it to us and we’ll read it with you line by line.

Why Burbank Homeowners Call Topside Attic Insulation Burbank for Johns Manville Work

The R-value is what the label says. The performance is what the blower-door test says. We care about the second number.

We’ve been working Burbank attics - including the older ranch-style homes in Magnolia Park - long enough to know exactly where the thermal bypasses hide in a 1960s rafter bay. Wes Okafor built this crew on sequencing the job correctly: air-seal every penetration first, then blow the cellulose or batts, so the R-value on the invoice actually matches the performance the homeowner measures on their utility bill.

Our 365-Day Done Right Promise applies to every job. If it’s not done right, we make it right. Calls are answered by a live person 24/7 - no voicemail loops, no callback windows measured in business days. Background-checked, uniformed technicians arrive on schedule with a text when they’re on the way. And because we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, and others, we recommend what fits your attic, not what moves our inventory.
