How Johns Manville Products Fail, and How We Fix Them

Johns Manville fiberglass and mineral wool products hold up well in Cypress attics, but they’re not immune to what Southern California rodents and time do to them. Here’s what we see most often, and what we do about it.

• Johns Manville ComfortTherm batts in older ranch homes near Cypress College: The kraft facing on ComfortTherm batts is a vapor barrier, but rats and mice tear into it for nesting material. Once that facing is shredded, the batt loses its shape and sags away from the drywall, creating thermal gaps. We remove the compromised batts, sanitize the area, and re-insulate before sealing entry points.
• Johns Manville Attic Protector blown-in fiberglass in homes along Katella Avenue: This loose-fill product settles over time, but rodent traffic makes it worse. Tunnels and nesting zones compress the fiberglass into dense clumps that hold moisture and odor. Our team vacuums out the contaminated material, decontaminates the deck, and blows in fresh JM Attic Protector at the correct depth for Cypress’s climate zone.
• JM Corbond III closed-cell spray foam* and rodent chewing: Spray foam isn’t a food source, but rats will gnaw through it to create pathways between wall cavities and the attic. The fix isn’t just patching the foam, it’s finding the entry point on the exterior and excluding it. We pair foam repair with rodent proofing so the problem doesn’t come back in three weeks.
• Johns Manville MR Faced Batts and attic moisture: In Cypress’s mild winters, condensation can form when warm interior air hits cold attic surfaces. Rodent urine and droppings accelerate the degradation of the facing, and once that facing fails, moisture moves into the batt itself. We inspect for this during every attic cleaning and flag batt replacement before mold becomes a bigger issue.
• OEM vs. aftermarket on JM access panels and attic hatches: We use Johns Manville material where it matters for warranty continuity, but for attic hatch weatherstripping and exclusion materials, we use commercial-grade rodent-proof mesh and door sweeps that outperform the original builder-grade stuff. Our goal is a sealed attic, not a parts list.

Every job starts with a phone call to (657) 837-1179, and a live person picks up, day or night. From there, here’s how a typical Johns Manville attic job goes in Cypress.

1. 1
   Inspection and thermal scan: We walk the attic and the exterior. We’re looking for rodent entry points, contaminated insulation, and any JM product that’s failed. Neil Ashford reads thermal weak spots fast, so you won’t wait long for a diagnosis.

3. 3
   Attic cleanout and sanitizing: We remove contaminated JM insulation, vacuum droppings, and sanitize the deck with an enzyme-based decontaminant that neutralizes rodent odor at the source.
4. 4
   Rodent proofing and exclusion: We seal entry points with rodent-proof mesh and commercial-grade sealants, paying special attention to roof-to-wall transitions and utility penetrations, the two most common access routes we find in Cypress homes.
5. 5
   Restoration and re-insulation: Fresh Johns Manville insulation goes in, whether that’s Attic Protector blown-in or ComfortTherm batts, matched to your home and budget. We’re one contractor, so the cleaning, proofing, and insulation all happen in one visit.
