How Johns Manville Products Fail – and How We Remove Them

Johns Manville makes solid insulation. But every product has a failure point, and in Pasadena’s dry heat and occasional monsoon-season humidity, certain patterns show up repeatedly. Here’s what we see and how we handle each one.

• Johns Manville ComfortTherm batts in pre-1990 Pasadena homes: These fiberglass batts were wrapped in a kraft paper vapor barrier that breaks down over decades. The paper gets brittle, the staples rust out, and batts slump away from the roof deck. You end up with gaps where attic heat pours into the living space. Removal is straightforward, but we’re careful with the old paper facing since it crumbles and gets airborne. We bag everything at the hatch, not in the house.
• Johns Manville Spider blown-in fiberglass, compressed and settled: Attic systems installed with Spider or Climate Pro blown-in fiberglass lose R-value as they settle. In a 1,200-square-foot Pasadena attic, we routinely find areas holding R-19 when the original install aimed for R-38. Settled material rarely needs full removal unless it’s contaminated, but when it does, our vacuum system pulls it clean down to the drywall so a fresh air-seal and new blown-in can go in properly.
• Water-damaged Johns Manville blown-in insulation after a Pasadena roof leak: This is the failure that warrants removal, not re-cover. Blown-in fiberglass or cellulose that’s been wet for more than 48 hours clumps, mats down, and loses almost all its thermal value. Worse, in Southern California’s heat, damp attic insulation breeds mold quickly. We remove all of it, dry the decking, check for rot, and recommend repairs before new material goes back in. Nobody should blow new insulation over a mold colony.
• Rodent-contaminated Johns Manville insulation: Rats and squirrels in Pasadena attics use fiberglass insulation as both bedding and a latrine. We’ve pulled out Johns Manville batts in the Chapman Woods and San Rafael neighborhoods that looked fine from the top but were soaked underneath. Full removal, sanitization, and air sealing are the only real fix. We also flag every access point so the next round of insulation doesn’t become another nest.
• Johns Manville AP Foil-Faced board insulation in older Pasadena homes: Rigid board used on knee walls and some attic ceilings holds up well, but the foil facing delaminates in high heat. Once the foil peels, the polyiso underneath slowly loses its thermal performance. Removal here means cutting panels out cleanly, which we do with the same care we’d use on any older structure. We’ll also check for asbestos in the mastic or tape on homes built before 1980, per California requirements, before we disturb anything.

Our Johns Manville Insulation Removal Process

Every job follows the same sequence. No shortcuts, no improvisation.

1. 1
   Call and assessment. You reach a live person at (626) 628-2368. We schedule a visit, and a background-checked, uniformed technician arrives inside the window we set.
2. 2
   Attic inspection and measurement. We assess insulation depth, condition, access, and the existing ventilation. We check for water damage, mold, and rodent sign before touching anything. This informs the written price.
3. 3
   Written price. You approve the number before we start. The price on the estimate is the price on the invoice. That’s The Garrison Standard, and we don’t waver on it.
4. 4
   Removal and cleanup. We use a gas-powered vacuum system that extracts Johns Manville insulation through a hose run to the truck, not through your hallway. Floors are covered, and we seal off the work area. What comes out goes into bags at the truck, not into your living room.
5. 5
   Post-removal inspection. With the attic down to bare decking, we show you exactly what we found: leaks, rot, wiring issues, air gaps. You decide what gets addressed before new insulation goes in.
6. 6
   Guarantee in writing. Every removal job carries our 365-Day Done Right Promise. If something fails within a year, we return at no charge. No fine print, no phone tag.
