How Johns Manville Products Fail - and How We Fix Them

• Climate Pro batts in coastal Long Beach attics absorb moisture from marine-layer humidity that rolls in overnight and lingers until noon. The kraft facing delaminates, the fiberglass compresses, and R-value drops 30 to 40 percent before you notice a temperature difference. We remove the compromised batts, seal the attic floor penetrations that let that moisture migrate upward, then replace with properly spec’d material.
• Formaldehyde-based batts from Johns Manville’s pre-2010 residential lines off-gas as they age, particularly in poorly ventilated Long Beach bungalows with original gable vents blocked by decades of paint. Homeowners report a sharp, chemical odor in summer. We remove these with PPE and negative-air containment, then air-seal before installing formaldehyde-free replacement.
• Blown-in fiberglass from the Attic Pro line settles unevenly in cathedral ceilings common in 1920s Long Beach homes, creating thermal bypasses where conditioned air escapes. Our fix: remove the settled material, dense-pack the cavity properly, and document pre- and post-install depth readings on every bay.
• Vermiculite insulation bearing the Zonolite brand (distributed by Johns Manville in some Western markets through the mid-1980s) contains asbestos in an estimated 70 to 80 percent of samples tested from Long Beach homes built 1945 to 1984. We coordinate licensed hazmat abatement, perform post-abatement clearance testing, then install new insulation with a documented photo record of the clean substrate.
• Multi-layer installations where Johns Manville batts were laid over older loose-fill trap moisture at the interface, accelerating compression and mold growth. We see this in Lakewood Village and California Heights homes where previous owners added insulation without removing the old. Our crew strips to the ceiling drywall, remediates any mold, then installs a single, properly spec’d system.

Our Johns Manville Insulation Removal & Replacement Process

1. 1
   Call and scheduling. A live person answers, 24/7. We book a site visit, usually within 24 to 48 hours for Long Beach addresses.
2. 2
   On-site assessment and measurement. We measure existing R-values and depth readings, identify the Johns Manville product line, and run a thermal camera scan to locate air leaks. Wes Okafor’s standard: a one-page report listing every measurement before we quote.
3. 3
   Written price and scope. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
4. 4
   Removal and air sealing. We remove the Johns Manville material using appropriate containment, then seal top plates, can lights, and penetrations. Measure first, then insulate - otherwise you’re just trapping the problem.
5. 5
   Replacement and documentation. New insulation goes in, we photograph every critical stage, and on applicable jobs 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.
6. 6
   Final walkthrough and 365-Day Done Right Promise. You receive the documented photo record, any blower-door numbers, and our written warranty. If it’s not done right, we make it right.

What Johns Manville Insulation Removal & Replacement Costs in Long Beach

What moves the price: attic access (hatch vs. scuttle vs. none), contamination level, whether the Johns Manville product contains formaldehyde requiring enhanced PPE, and whether we need to coordinate third-party hazmat for vermiculite. We also source from Owens Corning, Knauf, Rockwool, and other manufacturers if a different material suits your home better.
