How Johns Manville Products Fail - and How We Fix Them

• JM Spider Plus blown-in fiberglass packs down under rodent traffic. The long, interlocking fibers in this premium loose-fill product are designed for thermal performance, but they compress into hard mats where rats and squirrels run repeatedly. In Boerne homes near the Cibolo Creek watershed, we’ve pulled Spider Plus that had lost two-thirds of its loft after one season of rodent activity. We remove the compacted material, sanitize the deck, and reinstall only after exclusion is complete.
• JM Climate Pro batts wick urine and hold odor. The formaldehyde-free binder in these batts is better for indoor air quality, but the fiberglass itself doesn’t resist absorption. Once rodents saturate Climate Pro, the ammonia smell recirculates through ceiling penetrations every time the HVAC runs. We bag these batts for disposal rather than attempting surface cleaning, which would leave the odor source intact.
• JM Formaldehyde-free batts installed pre-2015 lack pest-resistant treatment. Older stock in Boerne’s 1980s and 1990s subdivisions, particularly near River Road Park, often shows no borate or other rodent deterrent. The fibers become nesting material. We note the manufacturing date during inspection and specify replacement with borate-treated product where the homeowner wants that protection.
• JM Kraft-faced batts delaminate in high-humidity attics. The paper vapor retarder separates from the fiberglass when rodent urine raises attic moisture levels, especially in Boerne’s spring and fall when temperature swings drive condensation. The facing then hangs in strips, creating voids and potential fire hazards near can lights. We remove the compromised facing entirely and assess whether an un-faced replacement with proper attic ventilation is the safer long-term choice.
• JM poly-encapsulated duct wrap gets torn for nesting. The reinforced scrim on this product is strong, but rodents chew through it to access the fiberglass core for burrow lining. Once the vapor barrier is breached, the duct beneath loses conditioned air into the attic. We patch or replace the wrap and seal the underlying duct with mastic before reinsulating, because new wrap over a leaking duct just hides the problem.

Our Johns Manville Attic Cleaning & Rodent Proofing Process

1. 1
   Inspection with photo documentation. We photograph every Johns Manville product line present, note manufacturing dates where visible, and map rodent entry points, contamination zones, and compressed insulation areas.
2. 2
   Written scope and price before work starts. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
3. 3
   Exclusion and sealing first. We seal the envelope first. Then fill it. Every entry point, from eave gaps to plumbing penetrations, gets metal flashing, hardware cloth, or sealant appropriate to the gap size and material. Rodent proofing fails if this step is rushed.
4. 4
   Insulation removal or in-place sanitization. Heavily soiled JM products are bagged and removed. Lightly contaminated material may be HEPA-vacuumed and treated with an enzyme-based sanitizer. We specify which approach in the written scope.
5. 5
   Replacement with matched or upgraded Johns Manville product. We source JM Spider, Climate Pro, or batts as specified, or discuss alternatives from Owens Corning, Knauf, or Rockwool if the homeowner prefers. No proprietary lock-in.
6. 6
   Final documentation. You receive a Documented Photo Record showing before, during, and after conditions, plus any blower-door readings if air sealing was part of the scope. The 365-Day Done Right Promise applies.

What Johns Manville Attic Cleaning & Rodent Proofing Costs in Boerne

Why Boerne Homeowners Call Topside Attic Insulation Boerne for Johns Manville Work

We’ve worked across the Hill Country since 2016, including the older homes near the Cibolo Nature Center where stack-effect air leakage was eating through cooling bills before a single batt ever went in. Wes Okafor runs a blower-door test before and after every applicable job, then hands the homeowner a printed pressure-differential report in pascals so the numbers are on paper. Our crews know Johns Manville product lines specifically, we also service Reflectix and other brands, and we never blow insulation over an unsealed attic floor. The 365-Day Done Right Promise, background-checked uniformed technicians, and a live person answering calls 24/7 are standard. Most importantly, you get a written price before any work starts, always.
