Owens Corning Home Energy Audit in Pomona: What to Know First
We provide independent Owens Corning home energy audit in Pomona, typically completed in 2 to 4 hours with a written report delivered same-day or next morning. Most audits run between $350 and $650 depending on home size and test scope, and we publish before-and-after blower-door numbers on every job where air sealing follows. This page is for Owens Corning owners in Pomona, Claremont, La Verne, and surrounding areas who want documented evidence of where their conditioned air is escaping and what it will take to stop it. Call (562) 242-7569 to schedule or text us a photo of your attic access if you’re not sure what you’re looking at.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Blown-In Insulation settling below labeled R-value in Pomona’s heat cycles. The loose-fill fiberglass compacts over 5-10 years in inland Southern California’s 100°F summer attics, creating a thermal bridge where the ceiling meets exterior walls. We measure settled depth with a ruled probe, calculate the current R-value against Owens Corning’s own coverage chart, and either top off to spec or remove and replace if the material is contaminated. Seal the leaks first. The insulation is just the last layer of the answer.
- FOAMULAR NGX rigid board gaps at rim joists and kneewalls. Owens Corning’s extruded polystyrene boards are specified tight to framing, but expansion and contraction in Pomona’s 40°F winter-to-summer swing opens seams that become convection loops. We find these with thermal imaging, then seal gaps with Owens Corning JointSealR foam tape or compatible low-expansion sealant before adding a continuous insulation layer.
- QuietZone batts compressed behind Knee Wall or attic knee-wall studs. The acoustic/thermal batts are often stuffed into 2×4 cavities by original builders, reducing their effective R-value by 30-50% and creating bypass channels. We remove, measure the actual cavity depth, and specify either proper-dimension batts or dense-pack cellulose that fills without compression.
- ProCat loose-fill installed over unsealed top plates and recessed can lights. This is the most common Owens Corning installation we audit in Pomona’s 1950s-1980s housing stock: blown fiberglass poured over a leaky attic floor. The insulation performs as an air filter, not a thermal barrier. Our protocol is blower-door guided air sealing of all penetrations, verified with a smoke pencil, before any new Owens Corning material goes in.
- WeatherLock mineral surfaced underlayment failing as a radiant barrier substitute. Some Pomona homeowners assume the reflective surface on Owens Corning roofing underlayment doubles as attic radiant barrier. It doesn’t. We measure attic deck temperatures with infrared guns, typically reading 140-160°F in July, and specify proper radiant barrier installation or cool-roof assembly when the roofing cycle allows.
Our Owens Corning Home Energy Audit Process

- 1
Call intake with scope lock. We ask square footage, year built, known comfort complaints, and whether existing insulation is Owens Corning or mixed brands. You get a written price range before we dispatch, per Haven Standard Clause 1.
- 2
Blower-door test - baseline. We depressurize the house to 50 Pascals and record CFM50, the single number showing how much air your envelope leaks. In Pomona’s older ranch homes near Ganesha Park, we regularly see 4,000+ CFM50 in 1,200-square-foot houses.
- 3
Thermal imaging and visual inspection. Our FLIR camera maps missing insulation, thermal bridging, and air leakage paths. We photograph Owens Corning product labels where visible to confirm original specifications.
- 4
Duct leakage testing (when accessible). We pressurize the duct system and measure leakage to outside, a separate figure from envelope leakage. Owens Corning duct wrap means nothing if the ducts are pulling 120°F attic air through seams.
- 5
Written report with prioritized scope. You receive blower-door number, thermal images with temperature callouts, a line-item repair scope with flat pricing, and documentation of what we found versus what the original Owens Corning installation was supposed to deliver.
- 6
Post-work verification (if we perform the air sealing). We run the blower door again and publish the new CFM50 so you can verify the performance change you paid for.
Before
AfterWhat Owens Corning Home Energy Audit Costs in Pomona
| Service Scope | Typical Range | What Moves the Price |
|---|---|---|
| Basic audit: blower door + thermal imaging + written report | $350 - $500 | Home size under 2,000 sq ft, single HVAC system, walk-up attic access |
| Extended audit: adds duct leakage test + combustion safety check | $500 - $650 | Two-story homes, multiple systems, finished attic or cathedral ceiling |
| Air sealing (performed same visit or scheduled after) | $1,200 - $2,800 | Attic square footage, number of recessed cans, top plate accessibility, whether existing Owens Corning insulation requires removal first |
| Insulation replacement with new Owens Corning material | $2.00 - $3.50/sq ft | Product line (AttiCat vs. ProCat vs. FOAMULAR), prep work required, access difficulty |
Homes in Pomona’s Philips Ranch area with engineered truss attics and open floor plans tend toward the lower end. The pre-1950s stock north of the 10 Freeway, with balloon framing and minimal original insulation, trends higher. We also service Reflectix radiant barrier systems where the original installer used that brand instead. Every estimate is free, every price is written before work starts, and we offer a Free Second Opinion on any competing written quote. Call (562) 242-7569 for your exact number.
Why Pomona Homeowners Call Topside Attic Insulation Pomona for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price before anyone lifted a tool and a Documented Photo Record when the crew left. Wes Okafor, who picked up his air-sealing fundamentals at Richard J. Daley College before California energy codes made it standard, runs a blower-door test on every audit so the R-value on paper matches what the house actually performs. Our 365-Day Done Right Promise applies to all completed work, and a live person answers calls 24/7 - no voicemail loops, no callback windows measured in business days. We’re independently owned and operated, not a franchise, and we source materials from Owens Corning, Johns Manville, Knauf, Rockwool, and others with no proprietary lock-in. You get the right product for your specific envelope, documented evidence of the result, and a flat price you knew before we started.
FAQs
No. A diagnostic audit performed by an independent service provider does not affect Owens Corning’s product warranty, which covers manufacturing defects, not installation or application issues. We document our findings separately and do not file claims on your behalf. If we find a material defect during audit, we flag it for your direct claim with Owens Corning. Call (562) 242-7569 to schedule - estimates are free.
The most reliable check is a blower-door test combined with thermal imaging. We regularly find AttiCat installations in Pomona that met coverage specs on day one but were blown over unsealed penetrations, or ProCat jobs where the settled depth now reads two inches below the labeled R-value. Our audit measures actual performance, not assumed performance. Call (562) 242-7569 for a written scope and price.
Adding over existing material is cheaper only if the existing layer is clean, dry, uncompressed, and installed over a sealed attic floor. In most Pomona audits, we find at least one of those conditions fails - rodent contamination, moisture staining, or bypass channels that make new insulation an expensive filter. We price both scenarios in our written report so you can compare actual numbers, not assumptions. Call (562) 242-7569 for your specific audit price.
We typically schedule within 48 hours, and same-day availability exists for urgent comfort or high-bill complaints. A live person answers calls 24/7 to book. The audit itself takes 2-4 hours depending on home size and test scope, and your written report arrives same-day or next morning. Call (562) 242-7569 to hold a slot.
We specify Owens Corning where it’s the right fit for your assembly, but we also work with Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in. If your original installation mixed Owens Corning batts with Reflectix radiant barrier, we audit the assembly as a system and recommend the material that actually solves the failure mode we documented. Call (562) 242-7569 to review your specific situation.
