Owens Corning Home Energy Audit in Canyon Lake: What to Know First
An Owens Corning home energy audit in Canyon Lake typically runs $280-$520 for a full diagnostic package including blower-door test, thermal imaging, and insulation inspection, with same-week scheduling available and a written price delivered before any work starts. We’re an independent Owens Corning service provider - not affiliated with or authorized by the manufacturer - and we’ve worked on Owens Corning systems in Canyon Lake homes since 2016, from the starter-grade AttiCat blown-in installations near the lakefront to the dense-pack ProCat series in newer builds off FM 306. If your energy bills are higher than your mortgage, the attic is usually confessing something. Call (737) 227-6219 for a free estimate with a written scope and flat price before anyone lifts a tool.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Fiberglas settling in Canyon Lake’s heat cycles. The loose-fill blown through the AttiCat machine settles 15-25% in the first two Texas summers, creating thin spots above top plates where conditioned air escapes into the attic. We measure the settled depth with a ruled probe, calculate the current R-value against the labeled bag count, and re-blow to spec only after sealing every top plate and penetration with fire-rated caulk and foam.
- ProCat dense-pack wall cavities pulling away from studs in high-humidity months. Owens Corning’s higher-density product can shrink slightly when interior humidity spikes during Canyon Lake’s August rainy periods, leaving gaps at stud bays that show up as cold stripes on our FLIR camera. We remove the compromised batts, air-seal the cavity with closed-cell spray foam at the perimeter, then reinstall fresh ProCat to manufacturer density - and we photograph every bay before closing.
- FOAMULAR 150 rigid board tape failure on crawl space walls. The acrylic tape Owens Corning specifies for FOAMULAR seams degrades faster in the alkaline soil contact common in Comal County crawl spaces. We find lifted tape and thermal bridging at the seams during our inspection, remove the failed tape, clean the XPS surface with denatured alcohol, and reseam with Dow Weathermate construction tape or foil-faced acrylic - materials we’ve tracked for longevity in local conditions.
- Ecotouch batts compressed by homeowner storage boards. Canyon Lake’s lake houses often have pull-down attic stairs with plywood decking laid over the insulation for storage, compressing Ecotouch batts from their labeled R-38 to an effective R-19 or lower. We document the compression with depth photos, quote removal of the decking (or installation of proper attic flooring stilts), and replace the crushed batts with new material at full loft - never leaving insulation squashed under a board.
- Radiant barrier foil delamination on roof decks with inadequate ventilation. Owens Corning’s radiant barrier sheathing can suffer adhesive failure when attic temperatures exceed 140°F regularly, which happens in Canyon Lake’s west-facing roofs with insufficient ridge venting. We inspect the foil surface with a borescope, measure actual attic ventilation against the 1:300 rule, and recommend corrective ventilation before any radiant barrier replacement - because new foil on a still-overheated deck fails again in three years.
Our Owens Corning Home Energy Audit Process

- 1
Call intake with a live person. No voicemail loop. We schedule a two-hour arrival window and text you when the technician is en route - Haven Standard: Arrive on schedule, you get a named technician.
- 2
Blower-door test first. We depressurize the house to 50 Pascals and record the CFM50 reading - a single number showing how much conditioned air you’re losing through gaps. In Canyon Lake homes built 2015-2020, we typically see 3,500-5,500 CFM50 before any sealing work.
- 3
Thermal imaging and insulation inspection. FLIR scan of walls, ceilings, and ductwork while the blower door is running, so leaks show as temperature anomalies under pressure. We probe insulation depth at ten points minimum and check for Owens Corning-specific issues: AttiCat settlement patterns, ProCat density, FOAMULAR tape condition.
- 4
Duct leakage test if indicated. We pressurize the duct system and measure leakage to outdoors - common in Canyon Lake’s flex-duct attics where Owens Corning insulation wraps but doesn’t seal the collar connections.
- 5
Written scope and flat price before any work starts. Haven Standard Clause 1: you get the blower-door numbers, the thermal images, our findings, and a single price for recommended work. No work starts without your signature on the scope.
- 6
Post-work verification and documented record. If we perform air sealing, we run the blower door again and hand you a printed report with pre- and post-CFM50 readings, plus photos of every sealed penetration. Seal the leaks first. Then insulate. The report tells you whether it worked.
Before
AfterWhat Owens Corning Home Energy Audit Costs in Canyon Lake
Most Owens Corning home energy audits in Canyon Lake fall between $280 and $520, depending on what the house needs and what we find.
| Service Component | Typical Range |
|---|---|
| Basic energy audit (blower door + thermal imaging + insulation inspection) | $280-$380 |
| Audit with duct leakage testing | $380-$480 |
| Full envelope diagnostic with combustion safety check | $420-$520 |
| Air sealing labor (if performed same visit, priced separately) | $1.80-$2.80 per square foot of attic floor |
What moves the price: house size (audit time scales with conditioned square footage), accessibility of attic and crawl space, whether ductwork is accessible for pressure testing, and if we find active rodent damage requiring photo documentation before insulation contact. We also service Reflectix radiant barrier systems and can compare performance data across brands during the same visit. Every estimate is free, written, and flat - call (737) 227-6219 for yours.

FAQs
No - a properly conducted energy audit does not void Owens Corning’s limited product warranty, though warranty claims for material defects still go through Owens Corning directly, not through us as an independent service provider. We document our findings separately and can provide photos to support your warranty submission if we discover a manufacturing issue. Call (737) 227-6219 to schedule - estimates are free.
Yes, we source Owens Corning materials through standard distribution channels, though we also carry compatible products from Johns Manville, Knauf, and others when they better suit your home’s condition or budget. We’re not locked to any single brand. We’ll show you the spec sheets and price both options in your written scope. Call (737) 227-6219 for a free estimate.
Repair is usually cheaper for localized issues - settled AttiCat in one attic zone, compressed batts under a storage board, failed tape on FOAMULAR seams. Full replacement makes sense when the product is past its effective lifespan, has widespread moisture damage, or was installed without proper air sealing underneath. We price both paths in your written estimate so you can compare. Call (737) 227-6219 for exact numbers - estimates are free.
Most Canyon Lake homeowners get an appointment within 3-5 business days, with same-week slots often available outside peak summer demand. Emergency scheduling for extreme energy bill spikes or suspected insulation failure can sometimes be accommodated within 48 hours. A live person answers calls 24/7 at (737) 227-6219 to check current openings.
You receive a printed report with the blower-door CFM50 reading, thermal images with temperature annotations, insulation depth measurements at each probe point, photos of any damage or concerns, and a written scope with flat pricing if work is recommended. On jobs where we perform air sealing, the post-work blower-door number is included so you can verify the performance change. Haven Standard: Have it in writing.
