How Johns Manville Products Fail - and How We Fix Them

• Climate Pro Blowing Wool settling below labeled R-value. The loose-fill fiberglass settles faster in Palo Alto’s seasonal humidity swings than the manufacturer tables assume, especially in older attics near Professorville or the Eichler tracts where roof ventilation was marginal from the start. We remove the compacted material, air-seal the deck, then reinstall to true settled thickness with a depth card photo for your record.
• AP Foil-Faced batts delaminating at the facing seam. The foil radiant barrier separates from the fiberglass core in attics that cycle above 140°F, common under dark composite shingles in Palo Alto’s south-facing roof planes. We strip the failed batts, inspect for condensation staining on the facing backside, and replace with a current Johns Manville product or an alternative like Knauf if the application warrants it.
• Formaldehyde-free batts absorbing moisture in crawl spaces. Johns Manville’s formaldehyde-free binder is less hydrophobic than older formulations; in vented crawl spaces around the Baylands or near groundwater, we’ve pulled saturated batts that dropped to half their R-value. We remove, dry the space, install vapor barrier if missing, then replace with Rockwool or a closed-cell spray foam better suited to the location.
• Vermiculite-era Johns Manville products in pre-1990 homes. Some Palo Alto ranch homes near Old Palo Alto and Ventura still contain vermiculite attic fill that may be cross-contaminated with asbestos; Johns Manville vermiculite was not their product line, but owners often misattribute all loose-fill in the space. We test first, abate through certified partners if positive, then replace with modern blown fiberglass or cellulose.
• Sound Control batts compressed by homeowner storage. The SRC-1 and SRC-2 products common in Palo Alto’s 1960s-1980s partition walls lose acoustic and thermal performance when compressed by plywood decking laid for attic storage. We remove the crushed batts, calculate the compressed loss, and reinstall to full dimension with baffles to prevent recurrence.

Our Johns Manville Insulation Removal & Replacement Process

1. 1
   Call and scope. A live person answers, schedules a site visit, and Wes Okafor or a senior tech arrives with a moisture meter, thermal camera, and inspection camera.
2. 2
   Written price before any work starts. We identify the Johns Manville product line, document its condition with photos, and deliver a flat price with scope and warranty in writing. No work starts without it.
3. 3
   Containment and removal. We isolate the work zone with poly sheeting and negative air if contamination is present, then remove the failed insulation using HEPA-filtered extraction to protect your HVAC and living space.
4. 4
   Air sealing before any replacement. Seal the leaks first. The insulation has nowhere to work if the air is moving around it. We seal top plates, can lights, penetrations, and chase ways, then run a blower-door test if scoped.
5. 5
   Replacement and verification. We install the replacement product to labeled depth or thickness, photograph the result, and provide a Documented Photo Record with R-value achieved, air-sealing locations, and final blower-door number if tested.
6. 6
   Close and warranty. Combustion safety check on any gas appliance in the attic space, cleanup, and your written 365-Day Done Right Promise documentation.

What Johns Manville Insulation Removal & Replacement Costs in Palo Alto

What moves the price: attic square footage, access difficulty (cathedral ceilings or tight scuttles), contamination requiring PPE and disposal surcharges, and whether the original Johns Manville product was installed over an unsealed deck that now needs remediation. We also service Reflectix radiant barrier systems where they were layered over or under Johns Manville products. Call (650) 352-3577 for a written estimate, no obligation.
