Owens Corning Home Energy Audit in Glendale: What to Know First
We provide independent Owens Corning home energy audit in Glendale, typically scheduled within 48 hours and completed in one visit. Most audits run between $280 and $520 depending on home size and test complexity, and you’ll get a written price before we start - no exceptions. This page is for Owens Corning homeowners in Glendale who’ve noticed uneven temperatures, rising utility bills, or suspect their insulation system isn’t performing as installed. We’re not affiliated with Owens Corning; we’re an independent service provider who works on their products daily across the Verdugo Woodlands, Rossmoyne, and Glenoaks Canyon neighborhoods. Call (213) 474-3828 to schedule or get a free second opinion on any written estimate you’ve already received.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat blown-in fiberglass settles below labeled R-value in Glendale’s dry heat cycles. The AttiCat system installs loose-fill PINK fiberglass at a settled density that can drop 10-15% below spec in homes near the Verdugo Mountains where daily temperature swings exceed 30°F. We measure actual depth against the bag chart, then supplement with dense-pack cellulose or re-blow to true R-38 or R-60, not nominal.
- ProCat loose-fill bridges over top plates, leaving thermal bypasses. In ranch-style homes common south of Colorado Boulevard, ProCat can miss the narrow gap between wall top plates and ceiling drywall. We pull back existing fill, seal with fire-rated caulk and rigid foam, then reinstall - because insulation over an unsealed bypass is just expensive noise reduction.
- FOAMULAR XPS rigid board gaps at butt joints after foundation settling. FOAMULAR 150 and 250 used in crawl space or basement applications in Glendale’s clay-heavy soil zones often gaps at seams as the slab shifts. We remove compromised sections, re-seal with Owens Corning recommended tape or compatible sealant, and verify with blower-door before closing up.
- QuietZone PINK acoustic batts compress in retrofitted wall cavities. Homeowners near Glenoaks Canyon who added QuietZone for sound control often find it compressed by subsequent electrical or plumbing work, destroying both acoustic and thermal performance. We extract, inspect cavity condition, and reinstall at proper 16-inch or 24-inch stud spacing with vapor-smart detailing.
- Ecotouch batts installed pre-2015 lack the current binder formulation. Older Ecotouch products in Glendale homes built during the 2000-2010 boom can sag in floor joist bays, especially where humidity spikes near the Los Angeles River corridor. We assess retention, replace if degradation is advanced, and always air-seal the subfloor plane first.
Our Owens Corning Home Energy Audit Process

- 1
Schedule and scope. Call (213) 474-3828; a live person answers. We confirm square footage, year built, known comfort issues, and whether you have prior audit documentation. You get a written price range by text or email before we dispatch.
- 2
Blower-door test first. We run a pressurization measurement - CFM50 - to establish baseline air leakage. In a typical 1,800-square-foot Glendale ranch, we often see 3,500-5,000 CFM50 before any work is touched.
- 3
Thermal imaging and insulation inspection. FLIR camera scan identifies Owens Corning product location, gaps, compression, or moisture staining. We photograph every finding for your Documented Photo Record.
- 4
Duct leakage test if applicable. For homes with attic ductwork, we pressurize the duct system and measure leakage to outside. Owens Corning insulation doesn’t fix air leaking from flex duct - we separate the problems.
- 5
Written findings and prioritized scope. You receive a printed report with blower-door number, thermal images, insulation condition by zone, and a flat-price scope for any recommended work. No work starts without your written approval.
- 6
Post-work verification on applicable jobs. If we perform air sealing, we re-run the blower door and publish before-and-after numbers. You keep the report.
Before
AfterWhat Owens Corning Home Energy Audit Costs in Glendale
| Service Component | Typical Range |
|---|---|
| Basic home energy audit (blower door + thermal imaging, no duct test) | $280 - $380 |
| Full audit with duct leakage testing | $380 - $520 |
| Additional insulation inspection in multiple zones (attic + crawl + walls) | $150 - $220 add-on |
| Written remediation scope with flat pricing | Included |
| Documented Photo Record | Included |
Price moves with home size, accessibility, and test complexity. A 3,200-square-foot two-story in Rossmoyne with finished attic space takes longer to test than a 1,200-square-foot bungalow near Adams Hill. We also service Reflectix radiant barrier systems and can evaluate hybrid installations where Owens Corning and Reflectix products overlap. Every estimate is free, and we honor our Free Second Opinion on any written estimate you’ve already collected.
Why Glendale Homeowners Call Topside Attic Insulation Glendale for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those were in Glendale’s varied housing stock - 1920s Mediterranean revivals, postwar ranch houses, and 1990s stucco boxes, each with different Owens Corning configurations. Wes Okafor learned the trade at Richard J. Daley College in Chicago, where the curriculum drilled air sealing before insulation long before it became standard practice here. Our crew runs blower-door tests before opening a single bag of material, and on applicable jobs you get before-and-after pressurization numbers in writing. The 365-Day Done Right Promise applies to all work, and calls are answered by a live person 24/7 - no voicemail loops, no callback windows measured in business days. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, and others; we specify what performs, not what locks you into a proprietary line.
FAQs
No. An independent energy audit is inspection-only and does not alter installed materials. If we recommend remediation, we use warranty-safe practices - compatible materials, proper density, and no compression of existing batts - and we document everything. Call (213) 474-3828 to schedule; estimates are free.
We source Owens Corning products through standard distribution channels and use quality-compatible materials where OEM is back-ordered or discontinued. We never substitute without your written approval, and we don’t claim exclusive or preferred status with any manufacturer. Bring us a competing quote for our Free Second Opinion.
Repair is usually cheaper if the product is less than 15 years old, properly installed, and only compromised in isolated areas - typically $400-$900 versus $1,800-$4,200 for full attic replacement in a Glendale home. We assess actual condition with thermal imaging and give you both numbers. Call (213) 474-3828 for an exact quote.
Most Glendale appointments are available within 48 hours, and we complete the audit in one visit of 2-3 hours. Same-week scheduling is common. You’ll get your written findings within 24 hours of the crew leaving.
We evaluate all major brands and mixed installations. Many Glendale homes have Owens Corning attic insulation with Reflectix radiant barrier in the garage or addition - we test the whole envelope as a system, not product by product. Your report covers performance, not brand loyalty.
