This page is for San Antonio homeowners dealing with Johns Manville fiberglass or spray foam that’s outlived its usefulness. Chase Whitaker and our crew have pulled enough JM material out of attics across this city to know exactly what you’re up against.

How Johns Manville Products Fail – and How We Fix Them

Johns Manville makes solid insulation, but San Antonio’s climate puts stress on it that other markets never see. Here’s what we encounter most often:

• JM ComfortTherm batts with moisture saturation. ComfortTherm’s poly-encapsulated facing is great for itch-free installs, but once a roof leak or AC condensate drip gets behind that facing, it traps water against the drywall. We see this a lot in older Alamo Heights homes with original HVAC pans. The batt looks fine from below until the ceiling starts staining. We remove the saturated sections, address the moisture source, and install a properly vented replacement.
• JM Attic Protector blown-in fiberglass that’s settled below R-value. Blown fiberglass loses loft over time, and in a San Antonio attic where temperatures swing 40-plus degrees daily from April through October, that settling happens faster than the spec sheet suggests. A 2010 install rated at R-38 might be performing at R-22 today. We test actual depth with a probe and remove only what needs to go before bringing your attic back to the code-appropriate R-value for our climate zone.
• JM Spider loose-fill with pest contamination. Spider’s low-dust formula is popular, but its texture is also friendlier to rodents than denser cellulose. Rat and squirrel activity in San Antonio attics leaves behind droppings, urine, and shredded material that can’t be salvaged. This is a complete removal job – we contain the space, vacuum everything out, sanitize, and run exclusion before new insulation goes in.
• JM Corbond III spray foam with improper off-gassing or adhesion failure. Corbond III is a closed-cell foam that works well when mixed correctly. But we’ve removed more than a few jobs where a previous contractor sprayed it too thick in a single pass, and the foam didn’t fully cure. The smell never goes away, and sections stay soft. The only fix is mechanical removal and a proper reapplication by a crew that owns its own rig and knows the chemistry.
• Legacy JM Formaldehyde-free batts from 2010 – 2015 with degraded kraft facing. This older facing breaks down in high-attic heat, releasing the fiberglass from its framing. You end up with batts slumped onto the ceiling drywall, doing almost nothing. It’s a removal-and-replace scenario, and we quote both options separately so you can decide what fits the budget.

Our Johns Manville Insulation Removal Process

1. 1
   Call and assessment. You call (254) 279-0971, and a live person picks up – 24/7, no voicemail. We ask about square footage, insulation type, and what you’re seeing. Then we book a visit at a live, trackable time.
2. 2
   Attic inspection and testing. We climb up, measure settled depth, check for moisture with a meter, and test any suspect foam sections. We’ll show you photos of exactly what we found. If your insulation is fine and something else is the problem, we tell you that instead of inventing work.
3. 3
   Written price, fixed before work starts. You get a line-item price for removal, disposal, any sanitation or air-sealing work, and the replacement insulation. No changes at the door.
4. 4
   Containment and removal. We seal off the attic access, run HEPA-filtered extraction equipment, and bag everything for proper disposal. For spray foam, we use a low-VOC mechanical removal process that won’t fill your home with dust. The work is documented with before-and-after photos, sent straight to your phone.
5. 5
   Replacement install. We re-insulate to San Antonio’s recommended R-value – typically R-38 to R-49 for attics – using materials matched to your home, not whatever’s left on the truck. We carry eight brands including Johns Manville, Owens Corning, and Rockwool.
6. 6
   Final walkthrough and written guarantee. You get your 365-Day Done Right Promise in writing, plus payment from a simple link. If anything’s not right within a year, we come back. No charge. No argument.

What Johns Manville Insulation Removal Costs in San Antonio

Every job is different, but here’s what our San Antonio customers typically see:

• Blown-in JM fiberglass removal, small attic (under 800 sq ft): $1,200 – $1,900
• Blown-in JM fiberglass removal, standard attic (800 – 1,500 sq ft): $1,800 – $2,800
• JM batt removal with moisture or pest contamination: $2,200 – $3,500, depending on sanitation needs
• JM spray foam removal (Corbond III or similar): $2,800 – $5,000+, since mechanical removal is labor-intensive

What moves the price: attic accessibility, contamination, disposal weight, and whether we’re also air-sealing or adding ventilation. Your replacement insulation is quoted separately and you choose the material. Call (254) 279-0971 for an exact quote – the estimate is free and the price we give you is the price you pay.
