Johns Manville Insulation Removal in Austin: What to Know First

Johns Manville insulation removal in Austin typically runs $1,200 to $3,800 depending on square footage, access difficulty, and the specific JM product line being pulled. Most full removals in Austin homes are completed in one day, with larger or multi-attic jobs taking two. We’re an independent Johns Manville service provider, which means we work on JM products every week but we’re not authorized by or affiliated with the manufacturer, so we call problems as we see them without a brand filter.

How Johns Manville Products Fail – and How We Fix Them

Johns Manville makes solid insulation products, but Austin’s climate and the age of many homes here create predictable failure patterns. Here’s what we pull out of Austin attics week after week:

• JM Blown-In Fiberglass (Climate Pro, Attic Protector): This is the most common JM product we remove in Austin. The failure isn’t usually the fiberglass itself, it’s the settling. After 15 – 20 years, blown-in fiberglass compresses by 20 – 30%, which drops its R-value per inch. In Austin attics that regularly hit 140°F in August, combined with decades of dust and occasional roof leaks, the material mats down and stops doing its job. We remove it completely, inspect the decking, and start fresh.
• JM Batt Insulation (ComfortTherm, R-13/R-19/R-30): JM kraft-faced batts are decent, but installation mistakes from the 1980s – 2000s are what we find. Batts stuffed too tight around wiring, gaps at top plates, or vapor barriers installed facing the wrong direction for Austin’s mixed-humid climate. In a humid climate like Austin’s, a misplaced vapor retarder traps moisture inside the wall cavity, which you don’t see until the drywall looks wavy and the batts are damp and sagging. The fix is full removal, air-sealing, and replacement with the right product for the assembly.
• JM ComfortTherm Batts with Formaldehyde-Free Binder: Older JM batts used a formaldehyde-based binder that off-gasses over time. If you smell a persistent chemical or sweet odor in your attic that gets stronger in summer heat, older JM batts are a likely source. Removal is the only real fix. JM moved to formaldehyde-free binders years ago, but Austin homes built before roughly 2005 often have the older product.
• JM Open-Cell Spray Foam (JM Corbond III, JM Open-Cell): When open-cell JM foam gets wet from a roof leak or inadequate ventilation, it holds water like a sponge against the roof deck. In Austin, where spring storms dump inches of rain and fall brings high humidity, wet open-cell foam is a mold and rot risk. We cut out the affected foam, dry the decking, and replace with either closed-cell foam or a ventilated assembly, depending on the roof.
• JM Airtite/BIBs (Blow-In-Blanket) Systems: These older JM dense-pack fiberglass systems were blown behind netting in walls and cathedral ceilings. They settle and develop voids over time, especially around outlets and window headers. On a removal, we open the cavities, extract the old material, and re-insulate with a product that won’t settle the same way. This work is more involved than an attic pull and costs more, but it’s the honest fix.

Our Johns Manville Insulation Removal Process

1. 1
   Attic Diagnostic: We start with a full attic inspection, measuring existing R-value, checking for moisture, and identifying exactly which JM product is in place and its condition. You get a written report photo set before anything is removed.
2. 2
   Written Price: Before we touch anything, you get a line-item price in writing. No revised number at the door, no “unforeseen conditions” upcharge unless there’s something genuinely structural we couldn’t see from the access point.
3. 3
   Containment and Protection: We seal off the attic hatch with poly, lay drop cloths from the entry to the attic, and set up negative air pressure where needed so fiberglass dust doesn’t migrate into your living space.
4. 4
   Removal: Our techs vacuum out the old JM material with HEPA-filtered extraction equipment, removing it down to the decking or drywall. We hand-remove batts, bag them, and carry them out, not just shove them into a corner.
5. 5
   Air-Sealing and Cleanup: Once the cavity is empty, we seal top plates, wire penetrations, and plumbing chases, then sweep and sanitize the space. You see photo proof of the empty attic and the sealed penetrations before we bring in new material.
6. 6
   Guarantee and Documentation: Every removal comes with our 365-Day Done Right Promise in writing and a digital invoice you can pay from a link. If anything’s not right within a year, we make it right, no charge.

What Johns Manville Insulation Removal Costs in Austin

Here’s what we quote for common JM removal scenarios in Austin. Actual pricing depends on square footage, attic height, access, and disposal fees, but this gives you a real sense of the cost before you call.

• JM blown-in fiberglass removal (1,200 – 1,800 sq ft attic): $1,400 – $2,600
• JM batt removal (small attic, 800 – 1,200 sq ft): $1,200 – $2,000
• JM spray foam removal (localized, under 200 sq ft): $1,500 – $3,800
• JM dense-pack wall cavity removal (per room): $800 – $1,500
• Full attic sanitization and air-sealing (add-on): $400 – $900

The biggest price drivers are square footage, attic access (pull-down stairs make it cheaper; a tight scuttle hole slows us down), and whether old JM spray foam is involved, which is a slower, more technical job than vacuuming out fiberglass. We’ll give you a written line-item estimate before anything gets started, with no charge to come out and quote. Call (361) 321-0817 and tell us your square footage. Chase has a signature line about this: “Tell me your square footage and I’ll give you a real number – no runaround.”
