Owens Corning Home Energy Audit Nationwide

Owens Corning Home Energy Audit in Pasadena: What to Know First

We provide independent Owens Corning home energy audit in Pasadena, typically completed in a single visit with your written price delivered before any work starts. Most audits we perform on Owens Corning systems run between $280 and $520, depending on whether you need a standard blower-door and thermal inspection or the full package including duct leakage testing. We’re not affiliated with Owens Corning; we service their products as an independent Owens Corning service provider, which means we work on what you actually own, not what a manufacturer wants to sell you next.

This page is for Pasadena homeowners who installed Owens Corning insulation or roofing components between 2015 and 2025 and suspect their building envelope isn’t performing to spec. Maybe your summer cooling bills spiked after a recent addition, or you’re feeling drafts in a Bungalow Heaven Craftsman that was supposed to be sealed tight. Call (213) 816-5351 for a free estimate. We’ll read your existing paperwork with you, no obligation.

How Owens Corning Products Fail - and How We Fix Them

• Owens Corning AttiCat blown-in fiberglass settling below labeled R-value. The AttiCat system installs at a higher lofted density than it maintains. In Pasadena’s dry heat, we’ve measured AttiCat installations in Madison Heights attics that settled from R-38 to an effective R-26 within seven years. We remove the settled material, air-seal top plates and can-light penetrations with fire-rated caulk and rigid baffles, then reinstall to true depth with a fresh blower-door target.
• Owens Corning Duration shingles creating thermal bypass at the deck. The SureNail strip on Duration shingles is excellent for wind uplift, but the raised fastening zone can create a slight gap at the roof deck if the original installer didn’t seat each shingle fully. During our thermal imaging inspection, we regularly spot these as linear cold strips running up Pasadena’s steeper pitches, especially above unvented attics. We document the pattern, seal from the interior where accessible, and recommend deck-level remediation if the gap is pulling conditioned air.
• Owens Corning ProPink LooseFill L77 compressing in crawl spaces with seasonal moisture cycling. Pasadena’s winter rains followed by summer dry spells create humidity swings in vented crawl spaces. L77 that looked fluffy in March can be matted and bridging over joist bays by October. We find this in the older homes south of Colorado Boulevard. Our fix: remove the bridged material, install a vapor barrier if none exists, then replace with a moisture-tolerant alternative or encapsulate entirely.
• Owens Corning FOAMULAR NGX 150 board stock gapping at seams after thermal expansion. Rigid foam boards expand and contract more than the framing they’re attached to. In Pasadena’s 40-degree daily temperature swings during Santa Ana events, we’ve found NGX 150 pulling away from perimeter walls in retrofitted additions, creating convection loops that read as ghosting on thermal cameras. We pull the boards, seal the gaps with closed-cell spray foam, and reinstall with proper expansion accommodation.
• Owens Corning EcoTouch batts installed without air sealing behind electrical boxes. EcoTouch is a solid batt product, but batt insulation doesn’t stop air movement, it only slows conductive heat transfer. We see this constantly in Pasadena’s 1940s and 1950s tract homes: batts stuffed around boxes with no foam seal, so the insulation is filtering air rather than blocking it. We pull the batt, seal the box to the drywall with acoustical sealant, and reinstall. The blower-door number always moves.

Our Owens Corning Home Energy Audit Process

1. 1
   Call and scheduling. A live person answers, 24/7. We book your audit, text you a technician name and photo, and send an arrival alert when they’re en route. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
2. 2
   Pre-audit documentation review. We read any Owens Corning paperwork you have - install dates, product labels, warranty cards - so we’re testing the actual system, not guessing at what got installed.
3. 3
   Blower-door test and thermal imaging. We run a pressurization reading to establish your baseline CFM50, then walk the house with a FLIR camera to map thermal anomalies against the air-leakage data. Two data sets, one picture.
4. 4
   Insulation inspection and duct leakage test if indicated. We probe accessible insulation for depth, density, and moisture content. If your ductwork runs through an unconditioned attic - common in Pasadena’s ranch-style homes - we run a duct blaster to measure how much conditioned air you’re losing to the attic before it reaches the room.
5. 5
   Written scope and price. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions.
6. 6
   Work execution with documented photo record. If you proceed, we complete the air sealing and insulation work, run a post-blower-door test, and deliver your before-and-after numbers plus a photo folder showing what we found and what we did. Seal the leaks first. Then insulate. The numbers will tell you why.
