Owens Corning Home Energy Audit in Palo Alto: What to Know First
We provide independent Owens Corning home energy audit in Palo Alto, typically completed same-day with written results delivered before we leave. Most audits run between $280 and $550 depending on home size and test scope, and we publish your before-and-after blower-door numbers when air sealing is part of the job. This page is for Owens Corning owners in Palo Alto who want to know whether their insulation, air sealing, or duct system is performing as specified, not for homeowners shopping generic energy audit templates. Call (650) 352-3577 to schedule or to get a free second opinion on any written estimate you’ve already received.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles below labeled R-value in older Palo Alto ranch homes. The AttiCat system specifies depth for a given R-value, but we’ve measured settled depths in Midtown and Old Palo Alto attics that dropped 2 to 4 inches below install spec after five to seven years. The fiberglass doesn’t degrade, it just compresses and shifts with roof deck movement and rodent traffic. We pull depth measurements across a grid pattern, compare against the original bag count and coverage chart, and recommend top-off or full replacement with corrected density.
- OC Foamular rigid foam board gaps at seams and penetrations, creating thermal bypasses. Foamular 150 and 250 are common in Palo Alto crawl space and basement perimeter jobs from the 2010s, but the boards were often butted without continuous bead sealant at edges or around plumbing penetrations. The R-value of the board is irrelevant if conditioned air washes behind it. We remove, re-cut where needed, and re-install with sealed seams and proper mechanical fastening per the manufacturer’s published detail drawings.
- PINK Next Gen Fiberglass batts installed without air sealing at top plates leak at the perimeter. This is the newest Owens Corning batt line we’re seeing in peninsula new construction, and the product itself is fine, the failure is installation sequence. Builders in Palo Alto’s tighter new builds sometimes insulate before the drywall crew seals the top plate to drywall interface. We pull back batts at suspect walls, seal the plate line with acoustic sealant or gasket, and re-install without compressing the facing.
- Owens Corning EcoTouch batts in vented attics show moisture staining near can lights. The batts don’t fail, the air sealing detail fails. Recessed can lights in pre-2015 Palo Alto homes are rarely IC-rated and almost never sealed to the drywall. Warm moist air hits the cold can in winter, condenses, and stains the batt below. We replace stained batts, install fire-rated covers or sealed LED retrofits, and verify with blower-door-directed infrared that the leak is gone.
- OC ProPink LooseFill in mixed rooflines creates uneven coverage at valleys and dormers. The blowing machine settings and hose technique that work for a rectangular ranch attic don’t translate to the complex roof geometries common in Professorville and the Professorville-adjacent additions. We find thin spots and wind-washed areas with traverse measurements and thermal imaging, then hand-place and stabilize fill in the problem zones rather than simply blowing more material that will settle the same way.
Our Owens Corning Home Energy Audit Process

- 1
Call and scope. A live person answers, we ask square footage, year built, known comfort complaints, and whether you have prior audit documentation. We schedule a two-hour arrival window and text when the technician is en route.
- 2
Exterior and interior walkthrough. We note construction type, attic access location, visible duct routing, and any Owens Corning product labels we can identify from prior work. We photograph existing conditions before touching anything.
- 3
Blower-door test and thermal imaging. We depressurize the house to 50 Pascals and record the CFM50 reading, then use infrared to map the leak paths the blower door reveals. This shows us where air is moving, not where we guess it might be.
- 4
Insulation inspection and R-value verification. We probe depth, check for compression and moisture, and identify the product line if it’s Owens Corning or another brand. For Owens Corning loose-fill, we compare measured depth against the bag count and coverage chart for the labeled R-value.
- 5
Duct leakage test if scoped. We pressurize the duct system and measure leakage to outside, since Palo Alto’s tight new builds can have duct leakage that dominates energy loss even when insulation looks correct.
- 6
Written report and pricing. You get the blower-door number, thermal images with annotations, a written scope with flat pricing, and our recommendation. No work starts without a signed written price. If you want a second opinion on another contractor’s estimate, we review it with you at no charge.
What Owens Corning Home Energy Audit Costs in Palo Alto
| Service Component | Typical Range in Palo Alto |
|---|---|
| Basic home energy audit (blower door + thermal imaging + insulation inspection) | $280 - $400 |
| Audit with duct leakage testing included | $380 - $550 |
| Air sealing only (top plates, penetrations, can lights) | $1,200 - $2,800 |
| Attic insulation top-off with air sealing | $2,800 - $5,500 |
| Full attic insulation replacement with air sealing | $4,500 - $9,000 |
What moves the price: attic square footage, accessibility (cathedral ceilings and tight crawl spaces take longer), existing insulation removal requirements, and whether we find active rodent damage that needs cleaning and proofing before new material goes in. Complex rooflines in older Palo Alto neighborhoods like Professorville or the Eichler tracts add measurement and labor time. We give you a flat written price before any work starts, and estimates are free. Call (650) 352-3577 for your specific number.
Why Palo Alto Homeowners Call Topside Attic Insulation Palo Alto for Owens Corning Work

We’ve been running jobs on the peninsula since 2016 under The Haven Standard, and our crew knows Owens Corning product lines from AttiCat through PINK Next Gen well enough to spot when the install detail failed, not the material. We also work with Reflectix and other brands, so if your audit reveals that a different product suits your assembly better, we don’t have a proprietary lock-in forcing an Owens Corning solution where it doesn’t fit.
Every applicable job gets before-and-after blower-door numbers published in your documentation. The 365-Day Done Right Promise applies to all completed work. Calls are answered by a live person 24/7, and our technicians are background-checked and uniformed. You get a named technician, a text when they’re on the way, and a Documented Photo Record on every visit.
Wes Okafor, who leads the company, grew up on Chicago’s South Side and learned the trade at Richard J. Daley College, where the curriculum ran heavy on air-sealing fundamentals before insulation ever came up. He’s been doing this work for over two decades. His signature line, which every crew member hears on day one: “Seal the leaks first. The insulation has nowhere to work if the air is moving around it.”
FAQs
No. Owens Corning product warranties cover material defects, not who inspects the installation. As an independent Owens Corning service provider, we document conditions without altering factory-applied labels or registered product information, so your warranty stays intact. If we find a material defect during audit, we flag it for your warranty claim with the photos and measurements you’ll need. Call (650) 352-3577 if you want us to review warranty paperwork with you.
We source Owens Corning materials through standard distribution channels, same as any contractor. For audit-related repairs, we specify the exact OC product line and bag count so you know what you’re getting. We also work with Johns Manville, Knauf, Rockwool, and other brands, so if an alternative product performs better for your specific assembly, we’ll tell you straight. No proprietary lock-in.
Replacement is warranted when settled or damaged insulation can’t be restored to labeled R-value with a top-off, or when air sealing requires full removal to access top plates and penetrations. We show you the depth measurements, the thermal images, and the price for both paths before you decide. Most Palo Alto homeowners with Owens Corning loose-fill over fifteen years old find that removal plus air sealing plus new material pays back faster than topping off a compromised base layer. Call (650) 352-3577 for a free estimate and we’ll run both numbers.
Most audits are scheduled within two to five business days, and the site work takes two to four hours depending on home size and test scope. Same-day scheduling is sometimes available for comfort or safety concerns. We text when the technician is en route, and you get the written report with blower-door numbers before we leave. Call (650) 352-3577 to check current availability.
You receive a written report with the blower-door CFM50 reading, annotated thermal images showing leak locations, insulation depth measurements plotted on a grid of your attic, a written scope with flat pricing for any recommended work, and a written warranty summary if work is performed. On applicable jobs, the before-and-after blower-door numbers are included so you can verify the air-sealing result. This is Haven Standard documentation, delivered before the crew leaves, not available on request later.
