How Johns Manville Products Fail – and How We Fix Them

We see the same failure patterns repeat across San Diego attics. Here’s what actually goes wrong with Johns Manville insulation in this climate, and how we address each one during removal.

• JM ComfortTherm batts with vapor-retarding facing trapping moisture against drywall. ComfortTherm is a batt line with a built-in facing on one side. In coastal San Diego zones like Point Loma or Ocean Beach, that facing installed on the wrong side traps humidity against the ceiling drywall. We pull the batts, air-seal the ceiling plane, and re-insulate with unfaced product or blown-in fiberglass so the assembly can dry.
• Blown-in JM Spider (spray-applied fiberglass) bonding to ductwork and framing. Spider is a JM product sprayed with adhesive. In San Diego attics with older duct systems, that adhesive makes removal slow work because the fiberglass is stuck to everything. Our crew uses a HEPA-filtered vacuum rig rated for this exact material, then removes the residual adhesive from ducts before any new insulation goes in.
• JM Attic Protector blown-in fiberglass settling below labeled R-value. Attic Protector settles over time, especially in unconditioned San Diego attics where big temperature swings between day and night cause the loose fill to compact. We measure depth before removal, then write the actual R-value you have versus what the bag claims. Most of the San Diego attics we inspect from the 1990s and early 2000s are running at 60 to 70 percent of their original label.
• Pest damage in JM batt and blown products. Rats and mice don’t care what brand you have, but JM fiberglass with its brownish tint hides rodent droppings better than white products from other manufacturers. That means San Diego homeowners often don’t realize they have a pest problem until we’re halfway through removal. We flag it, document it with photos, and recommend attic sealing before new insulation goes in.
• JM Formaldehyde-free batts degrading early near can lights and bathroom fans. JM was early to formaldehyde-free production, but the trade-off in some batches is earlier breakdown under direct heat exposure. In San Diego homes with old non-IC-rated can lights, we see JM batts that have turned brittle and dark right around the fixture. Removal includes proper sealing and baffling around those heat sources so the replacement product doesn’t meet the same fate.

Our Johns Manville Insulation Removal Process

Every job follows the same sequence, and you’ll get photos at each step through the Relay Standard: book online, get a live arrival time, receive before-and-after photo updates, and pay from a link when the work is done.

1. 1
   Attic inspection and measurement. We measure square footage, check depth, test for moisture, and identify exactly which Johns Manville product you have. ComfortTherm batts get handled differently than blown-in Attic Protector or Spider. We note the condition before a single bag is moved.
2. 2
   Written price and scope. You get the dollar figure in writing before work begins. No changes at the door.
3. 3
   Containment and removal. We seal off the attic access, run a HEPA-filtered vacuum line to the truck, and remove the JM material. For batts, we bag and carry. For blown-in and spray-applied, it’s vacuum work with a dedicated rig that keeps the dust out of your living space.
4. 4
   Air sealing and vent inspection. After removal, we inspect the ceiling plane for gaps around wires, plumbing, and framing. Chase Whitaker and the crew seal what needs sealing. This step is where a lot of the energy gain actually happens, and we don’t skip it.
5. 5
   Re-insulation and documentation. We install the replacement product, photograph everything, and send you a written guarantee with the digital invoice. If anything fails within 365 days, the Done Right Promise covers it, and we come back free.

What Johns Manville Insulation Removal Costs in San Diego

Here’s what we quote for common San Diego scenarios:

• Single-room batt removal (JM ComfortTherm): $450 – $800
• Full-attic blown-in removal (JM Attic Protector, 1,200 – 1,800 sq ft): $1,400 – $2,600
• Spray-applied JM Spider removal: $2,200 – $3,800 depending on adhesion to ducts and framing
• Removal plus new R-38 blown-in fiberglass: add $1,200 – $2,400 for the full attic

What moves the price: attic height and access, how much material is up there, whether we’re also sealing ducts or repairing pest damage, and the replacement product you choose. We carry materials from eight manufacturers, so we’re not locked into any one brand when it’s time to re-insulate. Call (619) 793-3676 for a written estimate. It’s free, and you’ll know the real number before you commit.
