How Owens Corning Products Fail - and How We Fix Them
We’ve pulled apart enough Owens Corning jobs across West Covina to know where things go sideways. Here’s what we see, and what we do about it:
- FOAMULAR XPS boards with moisture intrusion. Owens Corning’s rigid foam boards are solid, but when water finds its way behind them in a crawl space, the boards can hold moisture against the rim joist. We remove the affected sections, air-seal the actual source of the dampness, and reinstall dry board. In West Covina homes near the hills, this is a springtime pattern we know well.
- Traditional fiberglass batts installed without air sealing. Plenty of Owens Corning batts go in over leaky top plates and can lights. The insulation isn’t failing, but the assembly is losing conditioned air. We pull back the batts, foam-seal every penetration, and set the material back down. That’s the fix, not a replacement.
- Spray foam that didn’t cure correctly. When closed-cell foam is applied too thick in one pass, it can shrink or pull away from framing. We see this most often on garage ceilings in West Covina homes built in the 60s and 70s. Our fix is to remove the bad section, prep the surface properly, and recoat in controlled lifts so it cures tight.
- Open-cell foam in the wrong application. Open-cell has its place, but not under a roof deck that gets West Covina’s summer sun. We’ve fixed roof decks where open-cell absorbed moisture and lost R-value. We switch it to closed-cell in those spots and the problem stops.
- Improperly sealed rim joists. Rim joist spray foam fails when installers skip cleaning the surface or don’t run the foam deep enough into the cavity. Rodents, air leaks, and cold floors follow. We scrape, clean, and foam the full depth, then inspect every inch with a flashlight before we call it done.

FAQs
Owens Corning offers manufacturer warranties on many of their insulation products, but coverage depends on the product line and installation conditions. As an independent Owens Corning service provider, we don’t process manufacturer warranty claims, but we’ll inspect your job and tell you honestly whether the problem is a material defect or an installation issue. Our own work is backed by the lifetime Done Right Promise regardless of what the manufacturer covers. Call (626) 612-1532 and we’ll sort out what you’re actually dealing with.
Yes, in most West Covina homes, we can remove the failed section and recoat without tearing out the entire installation. Spray foam is a patchable material when the substrate is properly prepped, and we’ve done hundreds of targeted repairs that saved homeowners thousands compared to a full redo.
Repair is almost always cheaper if the foam itself is sound and only a section has failed. We’ll give you an honest recommendation based on what we find. If replacing makes more sense long-term, we’ll tell you that too, and explain the numbers. Estimates are free, so you’re never paying just to find out.
Most jobs we can schedule within a few days, and emergency work, like a failed rim joist letting in rodents or water, we treat as a priority. Call (626) 612-1532 and we’ll tell you exactly when we can be there. A live person answers around the clock, so you’re never leaving a message and hoping.
