Johns Manville Home Energy Audit Nationwide

Johns Manville Home Energy Audit in Boerne: What to Know First

We provide independent Johns Manville home energy audit in Boerne, typically scheduling within 48 hours and completing the full diagnostic same day. Most audits run between $280 and $520 depending on home size and whether duct leakage testing is included, and you’ll get a written price before we start - no exceptions. This page is for homeowners who already have Johns Manville insulation or roofing products in their building envelope and need to know whether those materials are performing as specified, or whether installation gaps or product degradation are driving up utility bills. Call (830) 529-7780 to book or text us if you prefer.

How Johns Manville Products Fail - and How We Fix Them

• JM Spider blown-in fiberglass settles below labeled R-value in Boerne’s humidity swings. Spider is engineered for open-cavity application with an acrylic binder, but in Hill Country homes where attic temperatures swing from 40°F winter mornings to 140°F summer afternoons, that binder can release early if the initial install moisture content was off. We measure settled depth with a probe ruler and recalculate effective R-value; if it’s dropped below 80% of label, we remove and reinstall to spec rather than blow more on top.
• JM AP Foil-faced polyiso board tape seams fail at the adhesive layer after 7-10 years. The foil facing is a radiant barrier only if the seams stay sealed; once tape lifts, you get convective looping behind the board in cathedral ceilings or knee walls. We find this with thermal imaging - a 2°F delta at the seam line - and reseal with foil tape rated for the temperature range, or replace with a mechanically fastened assembly if the substrate has degraded.
• JM Climate Pro loose-fill in mixed attic/crawl applications migrates toward the hatch or scuttle hole. This is a density issue, not a product defect: installers sometimes under-blow to speed the job, and the material walks over time. We document the redistribution with photos, then dense-pack to 0.5 pounds per cubic foot minimum or switch to a stabilized cellulose if access geometry prevents proper sidewall blowing.
• JM Linacoustic RC duct liner delaminates at the leading edge when exposed to return-air turbulence. The fiberglass mat separates from the airstream surface, shedding fibers into the handler. We catch this with borescope inspection during duct leakage testing; repair is removal and replacement with a coated liner or sheet metal conversion, not patching over the delamination.
• JM roofing membranes with White Cap TPO show accelerated UV chalking on south-facing pitches above 6:12. The reflective granules erode faster in Boerne’s 2,200+ annual sunshine hours, dropping solar reflectance index (SRI) below the 78 threshold that qualifies for utility rebates. We measure SRI with a field reflectometer and specify coating or cap-sheet overlay rather than full replacement if the membrane body is still sound.

Our Johns Manville Home Energy Audit Process

1. 1
   Call intake with scope lock. We ask which JM products are in your home, when they were installed, and what symptom prompted the call - high bill, hot room, musty duct air. You get a written price range by text before we dispatch.
2. 2
   Blower-door test - baseline. We depressurize to 50 pascals and record CFM50. In Boerne’s 1990s subdivisions near Johns Road, we typically see 3,800-5,200 CFM50 before any work; the number goes on your report.
3. 3
   Thermal imaging and insulation probe. FLIR scan of every JM surface, plus depth probe at 10 locations minimum. We photograph settled Spider, lifted AP Foil tape, or Climate Pro migration as we find it.
4. 4
   Duct leakage test if indicated. Pressurize supply and return separately to 25 pascals, measure leakage to outside. Linacoustic RC delamination shows up here as particle loading in the test fan.
5. 5
   Written findings with options. We rank repairs by cost-impact: air sealing first, then insulation restoration or replacement, then mechanical. Every option has a fixed price and a written scope.
6. 6
   Execution with retest. If you proceed, we seal, repair, or replace, then rerun the blower door and hand you the before-and-after pascals report. Photos are uploaded to your record by end of day.

What Johns Manville Home Energy Audit Costs in Boerne

What moves the price: attic accessibility (truss spacing, decked vs. floored), whether the JM product is wet or contaminated, and whether we need to coordinate with your HVAC contractor for duct work. We also service Reflectix radiant barrier products if your home has a mixed-manufacturer envelope. Every estimate is free, and we offer a free second opinion on any written quote you’ve already received. Call (830) 529-7780 for your exact number.

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

We’ve been independently owned and operated under The Haven Standard since 2016, and we’ve sealed and insulated over 9,000 homes - every one with a written price first and a documented record at the end. Our technicians are background-checked and uniformed; calls are answered by a live person 24/7, not a voicemail loop. Wes Okafor, our owner, learned the trade at Olive-Harvey College’s building technology program and has run blower-door tests before and after every applicable job for going on eighteen years. He keeps a well-used ACCA Manual J on his truck and will pull it out at your kitchen table if you want to understand why R-38 in your Boerne attic floor performs differently than R-38 in a cathedral ceiling. We source materials from Johns Manville, Owens Corning, Knauf, Rockwool, and others - no proprietary lock-in, so the fix matches the failure, not our inventory. Seal the envelope first. Then fill it.
