How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes solid insulation products, but Thousand Oaks attics punish any material that isn’t installed or maintained properly. Here’s what we actually find when we open up homes in this area.

• Closed-cell foam pulling away from the roof deck. We see this on Owens Corning closed-cell spray foam jobs where the foam was applied over a dusty or damp deck. The foam cures, but the bond never really takes, and within a few years you get hairline gaps that let conditioned air escape. In Thousand Oaks, the temperature swings between hot afternoons and cool marine-layer evenings make this worse. Our fix is removing the failed section and re-spraying after proper surface prep, not just patching over the gap.
• Open-cell foam losing its R-value from moisture saturation. Open-cell Owens Corning foam is vapor-permeable, which is fine in a dry climate, but Thousand Oaks gets enough coastal humidity that poorly vented attics can see condensation soak into the foam over time. Once saturated, it doesn’t insulate the way it should, and it can hold moisture against your framing. We diagnose this with moisture readings and fix it by correcting the ventilation first, then replacing the affected foam.
• Rim joist spray foam that was never thick enough. Builders and previous contractors sometimes spray a thin layer of Owens Corning foam at the rim joist to pass inspection and call it done. A half-inch of foam there does almost nothing for heat loss. We routinely find Thousand Oaks homes, especially 1980s and 1990s builds near the Conejo Valley Botanic Garden, where rim joists were under-sprayed. The fix is building up the foam to the proper depth for your climate zone.
• Garage ceiling foam that missed the edges. On Owens Corning garage ceiling spray foam jobs, we often find the perimeter was skimped, with thin coverage at the band joist where the garage ceiling meets the walls. That’s where hot air pours in during Thousand Oaks summers. We re-spray those edges and air-seal the transitions before adding insulation.
• Older Owens Corning batt and foam hybrids with gaps at the top plates. Houses that got a mix of Owens Corning batts in the walls and spray foam at the roof line sometimes develop gaps where the wall top plates meet the attic floor. Air moves through those gaps like a chimney. We air-seal the top plates before adding or adjusting the spray foam, which stops the stack effect that makes upstairs rooms hot in summer.

Our Owens Corning Spray Foam Insulation Process

1. 1
   You call, a person answers. No voicemail loop. We talk through what you’re seeing, your energy bills, and what rooms feel like, and we schedule a visit. Your technician’s name and photo come to you before we arrive.
2. 2
   We inspect the attic and take readings. We check existing Owens Corning foam for adhesion, moisture, thickness, and coverage. We look at ventilation, air leaks, and the condition of the roof deck. You get a plain-English explanation of what we found.
3. 3
   You get a written price. Before any work starts, we hand you a written estimate with the exact scope, materials, and cost. No verbal ballpark that changes later.
4. 4
   We do the work. Depending on the job, we remove failed foam, prep surfaces properly, and apply the right Owens Corning product, or we recommend an alternative from one of the other seven brands we stock if it’s genuinely a better fit. We tell you before we make that call.
5. 5
   We test and verify. We check coverage depth, adhesion, and air sealing at the critical points. We don’t call it done until it’s actually done.
6. 6
   You get the guarantee in writing. Every job carries our 365-Day Done Right Promise. If the repair fails within a year, we come back and fix it free. That’s labor and materials, in writing.
