CertainTeed Home Energy Audit in Glendale: What to Know First
An independent CertainTeed home energy audit in Glendale identifies exactly where your home is losing conditioned air and what your insulation is actually doing about it. We typically complete a full audit in two to three hours using blower door testing, thermal imaging, and duct leakage measurement, and you’ll have a written report the same day. We charge honestly for the diagnostic work: if you hire us for the fixes, the audit cost rolls into the job. Most Glendale homeowners start with the test and decide from there.
This page is for owners of CertainTeed insulation products, whether you know the exact product line or just suspect your home’s envelope isn’t performing. Call (747) 246-7237 to schedule, and a live person answers, day or night.
Key Takeaways:
- We’re an independent CertainTeed service provider, not a corporate warranty arm, so we tell you what’s actually wrong, not what sells product.
- Most Glendale audit findings trace back to installation gaps or age, not material failure, and many fixes are smaller than you’d expect.
- We’ve been doing energy audits and insulation work in the LA area since 2000, and our work carries a lifetime Done Right Promise.
- Audits include a blower door test, thermal imaging, and a thorough insulation inspection, not just a walkthrough with a clipboard.
How CertainTeed Products Fail and How That Skews Your Energy Audit
CertainTeed makes solid insulation products. Most of what we see on audits isn’t a factory defect; it’s what Glendale’s climate and time do to even the best-installed material. Here’s what we typically find when we test CertainTeed-insulated homes in this city:
- CertainTeed InsulSafe SP fiberglass blown-in settles and compresses. Attics in Glendale hit 130°F-plus in August, and that heat cycles the material. We regularly measure settled InsulSafe SP at R-19 or R-22 in homes that started at R-30. The attic still looks full, and the blower door test tells the truth. Fix is typically a top-up blow, not a full removal.
- CertainTeed OPTIMA blow-in, over batt or existing fill, hides gaps at eaves. We see this constantly in 1920s and 1930s Spanish-style homes near Kenneth Village and Rossmoyne. The old framing leaves voids at wall-to-attic transitions, and the OPTIMA settles away from them over a decade. Thermal imaging finds the channels; air sealing and a targeted fill closes them.
- CertainTeed fiberglass batts (R-13 and R-19 stock) get compressed behind Glendale’s older lath-and-plaster walls. Squeeze a batt to half its depth and you’ve cut its R-value by nearly half. That’s an air-sealing and dense-pack situation, not always a full teardown, but the audit nails down exactly which walls are worth opening and which aren’t.
- CertainTeed SmartBatt facing degrades and lifts in unconditioned crawl spaces. We work in a lot of hillside Glendale homes where the crawl space runs at 70% humidity all winter. The kraft facing on SmartBatt peels back at the staples and the batt slumps off the subfloor. Duct leakage testing in these homes almost always turns up surprising loss from the floor system because conditioned air gets pulled into that gap.
- CertainTeed DuctWrap and R-6/R-8 duct board fail at seams and saddles over time. We see this in attic-mounted systems all through Verdugo Woodlands and Montrose. One separated saddle joint can leak 15-20% of your system’s airflow into an unconditioned attic. A duct leakage test with a calibrated fan will find it in minutes, and the repair is usually localized, not a full duct replacement.
Most of these aren’t a knock against CertainTeed. They’re what any insulation contends with in a place that bakes all summer and gets marine-layer damp the rest of the year. The energy audit is how you find out which of these is actually happening, and which aren’t worth touching.
Our CertainTeed Home Energy Audit Process
Nobody wants to sign up for a mystery process. Here’s what a standard CertainTeed audit with us looks like, from first call to finished report:
- 1
You call (747) 246-7237 and talk to a person. We ask what you’re noticing: one room always hot, the AC running nonstop, an energy bill that doesn’t match the square footage. We schedule around your day, not ours.
- 2
We walk the house with you, not at you. We want to know which rooms feel wrong, when the house gets hot, what previous contractors told you. You know more about your house than we do on day one.
- 3
We run the blower door test. A calibrated fan mounts in an exterior door frame and depressurizes the house. The number we pull gives us your air leakage rate in CFM, and it’s the hardest data point in the audit. Most Glendale homes built before 1980 come in at two to three times the leakage you’d want.
- 4
Thermal imaging inside and out. We scan for temperature anomalies at walls, ceilings, outlets, and recessed light fixtures. CertainTeed insulation failures show up as cold or hot bands that light up the screen. We photograph everything so you can see exactly what we see.
- 5
Insulation and duct inspection. We go into the attic and, where accessible, the walls and crawl space. We measure depth, look for settling, compression, moisture, and rodent damage. We also inspect the ducts and note any separation, crushed runs, or missing insulation.
- 6
We sit down and go over the numbers. You get a written report the same day, with prioritized fixes and real costs. If the right move is a $600 air-sealing job rather than a $6,000 re-insulation, we tell you that. It’s what we’d want someone to tell us.
We don’t hard-sell remediation at the end. The report is yours, and it’s built to stand on its own. Do it right the first time or you’ll be doing it twice, and the second time costs more.
What CertainTeed Home Energy Audit Costs in Glendale
A complete home energy audit in Glendale with blower door testing, thermal imaging, and a written report typically runs between $350 and $650 depending on home size and access. Here’s how common audit scenarios break down:

We offer free second opinions on any written estimate and no trip charge within our county when you schedule an audit. If you hire us for the fixes the audit recommends, we credit the audit fee toward the work. Call (747) 246-7237 and we’ll give you an exact number before we step through the door.
Why Glendale Homeowners Call Walt’s Insulation for CertainTeed Work
We’ve been doing this work in the LA area since 2000, and we’re the one down the road, not an 800 number. When you call, a live person answers, and when a technician shows up, they’re background-checked, uniformed, and working for a company with a published address and a license number. That matters when you’re letting someone into your attic and your home.
We know CertainTeed products because we’ve tested and repaired thousands of them. We also carry and install other major lines like Owens Corning, Rockwool, Knauf, and Johns Manville, and we’re familiar with Reflectix radiant barrier in Southern California retrofit applications, so our recommendations aren’t limited to one product family. If another material makes more sense for our Glendale climate, we’ll say so.
Everything we do is covered by the Done Right Promise. If it’s not done right, we make it right. No fine print, no chase-the-warranty. Walt Brenner started this business with that rule, and it hasn’t changed.
FAQs: CertainTeed Home Energy Audit in Glendale
No. A diagnostic audit, even one that includes removing a small sample of insulation for inspection, does not affect a CertainTeed material warranty. The significant warranty issue is with DIY or unlicensed modifications that damage the product or the vapor barrier. Our audits are non-invasive and everything we document is photographed and recorded.
A full audit on a typical 1,500 to 2,500 square foot Glendale home runs about two to three hours, including the blower door test, thermal imaging, attic inspection, and written report. We finish with a same-day walkthrough of findings, so you walk away knowing what’s wrong and what it costs to fix. Call (747) 246-7237 to get on the schedule.
Most CertainTeed insulation failures we find in Glendale are localized. Settled blown-in gets a top-up, compressed batts get fluffed or replaced in targeted sections, and leaky duct insulation gets sealed and patched. We only recommend full replacement when the material is water-damaged, rodent-soiled, or so degraded that patching would cost more than starting over. That’s why the audit comes first.
We don’t combine the audit and major remediation in the same visit. The audit data tells us what needs fixing, and we want you to see those numbers before any repair work is scheduled. Small items, like sealing an obvious attic bypass or adjusting a slipped duct connection, we can often handle while we’re there if you give the go-ahead.
Settled InsulSafe SP blown-in fiberglass in older attics is the number one issue we document. Glendale’s summer attic temperatures accelerate settling, and most homeowners are surprised to learn their attic insulation is performing at two-thirds of its rated R-value. A blower door test and depth survey will confirm it in under an hour. Estimates are free, so you can know the number before committing to the work.
