How Johns Manville Products Fail - and How We Fix Them

• JM Spider Custom Insulation System - The loose-fill fiber glass in this blown-in system mats when rodents tunnel through it, creating bare thermal bridges across the attic deck. We remove the compacted sections, seal all entry points with galvanized steel mesh and foam, then reinstall to original R-value with fresh JM Spider or an equivalent loose-fill matched to your depth markers.
• JM Climate Pro BIBS (blow-in-blanket system) - The netting that holds this dense-packed fiber glass in wall and knee-wall cavities tears under rodent chewing, causing the fill to sag or spill into the attic floor. We extract the fallen material, repair the netting with compatible poly fabric, re-densify the cavity, and treat the attic space for droppings and urine proteins before any new insulation goes in.
• JM Formaldehyde-free fiber glass batts - These batts shred into long, irritating strands when rats or squirrels nest in them, and the shredded material actually wicks moisture more readily than intact batts. We bag and remove all contaminated batting, HEPA-vacuum the decking, apply an enzymatic sanitizer, then replace with new JM batts or upgrade to a blow-in system if the attic geometry allows better coverage.
• JM mineral wool (Sound & Fire) - The rigid, alkaline composition resists chewing better than fiber glass, but rodents still burrow beneath it and compress it at the edges, creating convection loops. We lift the boards or batts, treat the sub-surface, reinstall with proper edge dams, and add exclusion barriers at the eaves where New Braunfels roof rats typically enter.
• JM Kraft-faced batts in vented attics - The paper facing becomes a food source and nesting substrate in prolonged infestations, and in New Braunfels’ humidity cycles the compromised facing can mold before the fiber glass itself shows damage. We strip all faced material, treat the deck with antimicrobial, and typically recommend unfaced JM batts with a separate vapor-smart air sealing strategy instead of re-installing the kraft product.

Our Johns Manville Attic Cleaning & Rodent Proofing Process

1. 1
   Written price and scope - We inspect the attic, photograph the contamination, and deliver a flat price with line items for removal, sanitizing, exclusion, and re-insulation before anyone climbs back up.
2. 2
   Containment and removal - Crews set negative air and sealed walkways, then bag all contaminated Johns Manville product by type so we can identify the original R-value and depth for replacement matching.
3. 3
   Exclusion and sealing - We find and mechanically seal every entry point larger than 1/4 inch with steel mesh, concrete patch, or copper wool, then blower-door test the attic floor plane to locate hidden bypasses.
4. 4
   Sanitizing and deodorizing - Enzymatic treatment of urine proteins and droppings, followed by HEPA vacuuming of all surfaces; we document with photos before and after this step.
5. 5
   Re-insulation and verification - New Johns Manville or equivalent product installed to depth, with a post-job blower-door test so you leave with printed pre- and post-numbers. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
6. 6
   365-Day Done Right Promise - Written warranty delivered at completion; if rodents re-enter through our work, we return and correct it.

What Johns Manville Attic Cleaning & Rodent Proofing Costs in New Braunfels

Most attic cleaning and rodent proofing jobs in New Braunfels run between these ranges:

What moves the price: attic square footage, depth of existing Johns Manville product, whether the joists are walkable or require plank decking, extent of wiring/HVAC duct disturbance, and whether the home has active roof rat entry at the tile rake edges common in New Braunfels’ Hill Country-style builds. We also service Reflectix radiant barrier systems when those are present in the same attic. Call (830) 243-6352 - estimates are free and written, never verbal.
