Johns Manville Insulation Removal & Replacement in Burbank: What to Know First
As an independent Johns Manville service provider, we remove and replace failed Johns Manville insulation systems in Burbank homes, typically completing attic jobs in one day with a written price locked before work starts. Most removal-and-replacement projects in Burbank run between $2,800 and $6,400 depending on square footage, contamination level, and whether the original product was blown-in fiberglass, batts, or rigid board. We’re not affiliated with Johns Manville; we simply know their product lines well enough to remove them safely and replace with material that performs. This page is for homeowners who found a Johns Manville label in their attic, noticed uneven temperatures, high bills, or suspect rodent damage, and want a straight answer on whether the material can stay. Call (213) 816-1699 for a free written estimate with no work obligation.
How Johns Manville Products Fail - and How We Fix Them
- TempControl blown-in fiberglass settles below labeled depth in Burbank’s dry heat. The Magnolia Park and Hillside area attics we work regularly show 20-30% settling after 8-12 years, creating thermal gaps near eaves where R-value drops to half the bag claim. We remove the settled material entirely, air-seal top plates and can-light penetrations, then reinstall to a measured, documented depth with a depth-and-coverage report you keep.
- ComfortTherm batts degrade around HVAC penetrations in 1960s ranch-style ceiling joists. The kraft facing delaminates where Burbank’s summer attic temperatures exceed 140°F, exposing the fiberglass and creating a vapor-drive problem toward conditioned space. We pull the compromised batts, seal the boot-to-drywall junction with fire-rated caulk and collar dams, then replace with batts or blown-in depending on joist spacing and your preference.
- AP Foil-faced rigid board traps moisture when installed without proper vented air gap. We’ve found this in Burbank hillside homes where a previous contractor laid AP Foil directly against roof decking in a “hot roof” assembly that wasn’t actually sealed. The foil becomes a condensing surface; we remove the water-damaged boards, assess sheathing condition, and redesign the assembly with proper venting or convert to an unvented approach with spray foam if the structure allows.
- Formaldehyde-free batts from pre-2010 production attract rodent nesting. Johns Manville eliminated formaldehyde binders earlier than competitors, which made the material safer to handle but slightly more appetizing to roof rats common in Burbank’s mature tree canopy. We remove contaminated batts with HEPA-contained extraction, sanitize the substrate, rodent-proof entry points with steel mesh, and reinstall with borate-treated cellulose or fresh fiberglass per your choice.
- Micro-Aire spun fiberglass loses loft after minor roof leaks. Even a single winter rain intrusion through Burbank’s occasional wind-driven storms compresses Micro-Aire’s fine fibers permanently; they don’t rebound like denser products. We spot-remove the flattened sections, verify decking dryness with a moisture meter, and replace with matching material or upgrade to a more flood-tolerant product if the leak risk persists.
Our Johns Manville Insulation Removal & Replacement Process
- 1
Site visit with written price. We measure attic square footage, identify the Johns Manville product line, test for asbestos if the home predates 1990, and give you a flat price in writing before anyone schedules removal. Haven Standard Clause 1: no work starts without it.
- 2
Containment and HEPA extraction. We seal the attic hatch with a temporary barrier, run negative air if contamination is present, and remove material with vacuum systems that exhaust outside - not into your hallway.
- 3
Substrate inspection and air sealing. With insulation out, we photograph every penetration, seal top plates, wire holes, and can lights with fire-rated foam or caulk, and document the blower-door reading if this is an air-sealing job.
- 4
Material selection and replacement. We source replacement from our supplier network - Johns Manville, Owens Corning, Knauf, or others - with no proprietary lock-in. You choose; we install to labeled depth with verified coverage.
- 5
Documentation and final test. You receive a Documented Photo Record, depth-and-coverage report, and where applicable, before-and-after blower-door numbers. The 365-Day Done Right Promise begins when we leave.

Why Burbank Homeowners Call Topside Attic Insulation Burbank for Johns Manville Work
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-sealing every penetration first, then blowing in the cellulose or batts, so the R-value on the invoice actually matches the performance the homeowner measures on their utility bill. The R-value is what the label says. The performance is what the blower-door test says. We care about the second number.
Our materials come from Johns Manville, Owens Corning, Knauf, Rockwool, and others - no single-brand lock-in. If your situation suits Reflectix radiant barrier as part of the replacement assembly, we’ll say so and install it. Calls are answered by a live person 24/7, and every technician is background-checked and uniformed. You get a named technician and a text when they’re on the way. Under Haven Standard: Arrive on schedule, written price before work starts, documented record when we leave.
FAQs
Johns Manville’s limited warranty on installed insulation products typically covers manufacturing defects, not field removal, and most original warranties have expired by the time removal is needed. As an independent service provider with no manufacturer affiliation, we don’t represent Johns Manville’s warranty position; we can tell you whether your remaining material shows a defect pattern worth documenting before removal. Call (213) 816-1699 and we’ll review what you have.
Yes, we source current Johns Manville lines through our regular supplier network, though we may recommend a different product if your original line has been discontinued or if a Knauf, Owens Corning, or Rockwool equivalent performs better for your specific Burbank attic conditions. No proprietary lock-in means you choose; we install. For an exact match quote, call (213) 816-1699.
Spot repair is cheaper upfront - typically $800-$1,800 - but rarely lasts in Burbank’s heat-cycling attics because new material adjacent to settled old material creates thermal boundaries that show up on your bill. Full removal and replacement costs more initially but delivers measurable, documented performance. We quote both honestly; most homeowners who plan to stay 5+ years choose full replacement. Call for a written comparison.
Most Burbank attic removals start within 3-5 business days of estimate approval, or next-day for contaminated material posing active air-quality concerns. We don’t manufacture urgency - we schedule for when you need it and when we can staff it properly with our own crew, not subcontractors. Call (213) 816-1699 to check current availability.
Yes, and we treat every pre-1990 vermiculite job as potentially asbestos-containing until a Burbank-certified lab says otherwise. We coordinate third-party abatement when needed, then complete the replacement with your choice of modern material. The $350-$500 test fee is credited toward your job if you proceed. Call (213) 816-1699 to schedule sampling.
