How Johns Manville Products Fail - and How We Fix Them

• JM Spider blown-in fiberglass settles below labeled R-value in Tustin’s heat-cycling attics. The loose-fill product was common in 2005-2015 builds around Tustin Legacy and Orchard Hills. After a decade of 100°F summer peaks and 45°F winter lows, Spider compacts to 70-80% of its installed thickness. We remove it with a commercial vacuum system, verify the depth with a probe, and replace with new blown-in at the corrected depth for true R-38.
• JM Formaldehyde-free batts degrade at the paper facing in humid crawl spaces. The kraft paper vapor retarder on pre-2012 batts absorbs moisture from Tustin’s occasional heavy rains and clay-heavy soils, delaminating and dropping insulation onto the ground. We pull the batt, assess the joist cavity for mold, and install unfaced Rockwool or new JM unfaced batts with a proper vapor barrier.
• JM vermiculite from pre-1990 installations requires asbestos testing before disturbance. Not all JM vermiculite contains asbestos, but the Libby, Montana source cross-contaminated some lots. We collect a sample, send it to a certified lab, and hold the job until results return. If positive, we coordinate with a licensed abatement contractor; if negative, we proceed with full removal and HEPA cleanup.
• JM High-R batts compress when homeowners store boxes on them. The High-R line achieves its rating partly through loft; stack holiday decorations on it for two seasons and you’ve got R-19 performing like R-13. We remove the compressed sections, air seal the floor if it wasn’t done originally, and reinstall with catwalks and storage platforms so the insulation keeps its thickness.
• JM ComfortTherm encapsulated batts lose their polyethylene wrap in rodent-affected attics. The plastic shell tears where rats nest, exposing the fiberglass and creating a contamination vector. We remove the compromised batts, rodent-proof with steel mesh at entry points, sanitize the deck, and replace with fresh material. The encapsulated wrap is a good product, but it doesn’t survive chewing.

Our Johns Manville Insulation Removal & Replacement Process

1. 1
   Call and schedule. A live person answers 24/7. We book a site visit, and you’ll get a text when the technician is en route.
2. 2
   Attic inspection and documentation. We photograph the existing Johns Manville product, note the series and approximate install date, and run a blower-door test if air sealing is in scope. The reading gives us a baseline in CFM50.
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 disposal. We use a commercial insulation vacuum with HEPA filtration, bag the material per local code, and haul it to an approved facility. Contaminated or asbestos-positive jobs follow separate protocol.
5. 5
   Air sealing first, then insulation. Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can. We seal top plates, can lights, plumbing penetrations, and chase openings.
6. 6
   Replacement and verification. New insulation goes in at specified depth or thickness. On applicable jobs, we run a second blower-door test and publish the before-and-after numbers. You get thermal images, the written R-value report, and a Documented Photo Record before the crew leaves.

What Johns Manville Insulation Removal & Replacement Costs in Tustin

Price moves with attic square footage, accessibility (steep roof pitch adds time), contamination level, and whether the original install skipped air sealing. We also service Reflectix radiant barrier systems where those were layered over or under JM products. Every estimate is free, and we offer a Free Second Opinion on any written estimate you’ve already received. Call (657) 286-7673.
