How Johns Manville Products Fail - and How We Fix Them

Johns Manville makes solid insulation. We install it ourselves. But in Pomona attics, certain conditions turn even good material into a rodent’s nest and a homeowner’s headache. Here’s what we see on Johns Manville jobs specifically.

• Johns Manville ComfortTherm batts with rodent damage. ComfortTherm’s kraft facing holds moisture well, which is fine until a rat tears it open and nests inside. The facing wicks urine downward into the fiberglass, spreading odor across a much larger area than the nest itself. We remove the contaminated material completely, not just the visible nest, because the smell lives in the facing.
• Attic Protector blow-in fiberglass compacted by rodent traffic. Johns Manville’s blown fiberglass loses R-value when compressed, and rats create paths that crush insulation down to a fraction of its original depth. You’ll see cold spots on your ceiling directly under those runways. We remove and replace the compacted areas and seal the entry points so it doesn’t happen again in six months.
• JM Climate Pro batts with dust and particle buildup in Pomona’s dry air. Pomona sits in a valley that traps dust and wildfire smoke, and Climate Pro’s open fiberglass surface collects it. After years without cleaning, the insulation carries more debris than fiber. We’ll tell you honestly whether to clean or replace, Neil Ashford has told more than a few Pomona homeowners their insulation wasn’t worth saving.
• Johns Manville foam board sheathing chewed at the eaves. In older Pomona bungalows near Ganesha Park, we see JM Polyiso foam board at the roofline where rats gnaw through to reach the attic. The entry point is almost always at the eave gap or a vent screen that’s rusted out. We replace the damaged board section and install steel mesh exclusion at every vulnerable point.
• Rodent-damaged Johns Manville vapor barriers creating moisture problems. When rats tear up the vapor barrier under your Johns Manville insulation, Pomona’s winter temperature swings create condensation against the drywall. Mold follows. We repair or replace the barrier as part of the restoration, not as an afterthought.

Our Johns Manville Attic Cleaning & Rodent Proofing Process

1. 1
   Call and assessment. You call (626) 341-0830, a live person answers, and we schedule a visit. We inspect the attic, identify the insulation type, and map every entry point a rodent could use.
2. 2
   Exclusion first. We seal gaps, vent openings, and eave access with galvanized steel mesh and pest-block foam. No cleaning job sticks without exclusion. This is the step general contractors skip.
3. 3
   Contaminated material removal. We bag and remove soiled Johns Manville insulation by hand, not with a vacuum that spreads dust through your home’s air. Dual HEPA filtration runs throughout.
4. 4
   Sanitizing and decontamination. We treat surfaces with an antimicrobial that breaks down urine salts and eliminates odor at the source. This step matters with fiberglass, which holds odor longer than cellulose.
5. 5
   Restoration. We install fresh Johns Manville, Owens Corning, or Rockwool insulation matched to your climate zone and budget, then re-seal any air gaps we found.
6. 6
   The 90-Day Done Right Promise. If anything isn’t right, we make it right. Written commitment, not a handshake. Most jobs are completed in a single visit.
