Owens Corning Home Energy Audit in Santa Clarita: What to Know First
We provide independent Owens Corning home energy audit in Santa Clarita, typically completing the full diagnostic visit in 2 to 3 hours with same-day scheduling available most weeks. Most audits run between $350 and $650 depending on home size and which tests are needed, and we put that price in writing before we start. This page is for Owens Corning owners in Santa Clarita who want to know why their insulation isn’t performing as expected, whether the original install missed air sealing, and what the fix actually costs. Call (747) 294-2764 for a free estimate with a written price before any work starts.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat blown-in fiberglass settling in unsealed attics. The PINK Fiberglas AttiCat system performs to spec when the attic floor is sealed first, but in Santa Clarita we regularly find it blown directly over leaky top plates and can-light penetrations. The R-value drops as air moves through the insulation. We remove or work around the settled material, seal every penetration with fire-rated caulk and rigid foam, then reinstall to proper depth with verified coverage.
- FOAMULAR rigid board gaps at rim joists. Owens Corning FOAMULAR XPS is a solid product, but cut-it-and-leave-it installs in crawl spaces leave thermal bridging at the seams. In older Santa Clarita homes near Canyon Country, we’ve measured 15-degree temperature differentials at those gaps. We tape seams with acrylic adhesive tape and add a continuous air barrier so the board actually performs at its rated R-value.
- QuietZone duct board degradation in high-heat attics. Santa Clarita’s 100-plus summer days cook attic ductwork. QuietZone acoustic duct board can delaminate when attic ventilation is inadequate, sending conditioned air into the roof cavity instead of the living space. We test for leakage with a duct blaster, replace degraded sections, and often add radiant barrier or improve ventilation so the repair lasts.
- ProPink LooseFill uneven distribution over irregular framing. ProPink installs fast, but trusses and dropped soffits in Valencia-area homes create shadow zones with thin or missing coverage. Our thermal imaging catches these cold spots during the audit. We add targeted dense-pack or reposition existing material rather than blowing more over the problem.
- WeatherLock Flex underlayment trapping moisture in vented assemblies. WeatherLock is a quality ice-and-water shield, but when it’s used as a general air barrier in mixed-climate assemblies without proper drying strategy, we find moisture accumulation in Santa Clarita’s spring humidity swings. We diagnose the assembly, remove compromised material if needed, and specify the right barrier for the specific location.
Our Owens Corning Home Energy Audit Process

- 1
Schedule and scope. You call (747) 294-2764, a live person answers, and we book a 2-to-3-hour window. We confirm home size, age, and any known comfort issues. A written price arrives by text or email before we show up.
- 2
Blower-door test - baseline. We mount a calibrated fan in an exterior door and depressurize the house to 50 pascals. The CFM50 number tells us, in one figure, how much conditioned air is escaping through the building envelope. We write it down. The report goes home with you. The numbers don’t lie, and you shouldn’t have to take anyone’s word for it.
- 3
Thermal imaging and physical inspection. Our FLIR camera maps surface temperatures across walls, ceilings, and duct runs. We inspect the attic for insulation type, depth, and distribution; check for top-plate gaps, recessed can lights, and chimney chases; and examine crawl spaces for rim-joist sealing and vapor barrier condition.
- 4
Duct leakage test if indicated. When ductwork runs through unconditioned space, we pressurize the system and measure leakage to outside. In Santa Clarita, we’ve found systems losing 25 to 40 percent of airflow before any air reaches the registers.
- 5
Written findings and prioritized scope. You get a printed report with blower-door number, thermal images, insulation R-value map, and a line-item scope ranked by cost-effectiveness. No work starts until you approve a flat written price.
- 6
Post-work verification. On jobs we perform, we run the blower door again and hand you the before-and-after numbers. Photos document every step. The 365-Day Done Right Promise applies.
Before
AfterWhat Owens Corning Home Energy Audit Costs in Santa Clarita
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Basic home energy audit (blower door + thermal imaging) | $350 - $500 | Home size, number of HVAC zones, attic accessibility |
| Audit with duct leakage testing | $500 - $650 | Duct accessibility, number of returns, need for register sealing |
| Attic air sealing (typical 1,800 sq ft home) | $1,200 - $2,400 | Can-light count, chimney chase complexity, existing insulation condition |
| Attic insulation top-off or replacement | $2.00 - $3.50/sq ft | Material type, desired R-value, prep work required |
Most Santa Clarita homes built between 1985 and 2010 need air sealing before any new insulation makes financial sense. Adding R-value over a leaky attic is paying to heat and cool your roof cavity.

Our difference is measurable: before-and-after blower-door numbers on every air-sealing job, printed and signed. The Haven Standard means flat pricing, named technicians, text alerts when we’re en route, and a live person on the phone 24/7. No voicemail loops. No callback windows measured in business days. And if you’re comparing quotes, bring us any written estimate - we’ll read it with you, no charge.
FAQs
No. As an independent Owens Corning service provider, our audit does not affect manufacturer warranties on installed materials. Warranty coverage applies to product defects, not to diagnostic work performed by qualified contractors. If we find an install issue that should fall under warranty, we document it and point you toward the right claim channel. Call (747) 294-2764 if you want us to review your warranty paperwork during the audit.
Repair is viable when the material is dry, uncontaminated, and simply underperforming due to air leaks or thin coverage. Replacement makes sense when fiberglass is compressed by storage traffic, compromised by rodent activity, or mixed with incompatible materials that prevent proper air sealing. We make that call with thermal imaging and moisture readings, not guesswork. Our written scope breaks out both options when both are possible.
Most audits schedule within 3 to 5 business days, and we hold same-day slots for urgent comfort or efficiency concerns. Spring and early summer fill fastest as homeowners react to the first high bill. Call (747) 294-2764 - a live person will check real availability and lock in your window.
We use OEM Owens Corning materials when they are the right spec for the repair, and quality aftermarket when another manufacturer’s product performs better for the specific application. We do not lock ourselves to any single brand. Every material is named in your written scope before work starts, with no substitutions without your approval.
You receive a printed report with the pre-audit blower-door CFM50 number, thermal images with temperature annotations, an insulation R-value map of attic and walls, duct leakage percentage if tested, and a prioritized scope with flat prices. On jobs we perform, the post-work blower-door number and a photo record are added. Everything is dated and signed. Haven Standard Clause 1: have it in writing.
