Spray Foam Litigation: What It Actually Established About Fixing Bad Jobs
When people search for what to do about a spray foam problem, they usually find one of two things: a manufacturer's page insisting the product is safe when correctly installed, or a repair contractor pitching a quick fix. What's harder to find, and more useful, is what actually happened in the real disputes over genuinely defective spray foam installations — because those cases establish something concrete about what a real fix looks like.
The Cases in Question
Several federal class-action lawsuits have been filed against major spray polyurethane foam manufacturers, including cases naming Demilec and Masco Corporation, centered on defective or improperly-curing spray foam installations causing real property damage and health complaints. These aren't fringe complaints — they're organized, documented litigation with real discovery, expert testimony, and settlement or judgment outcomes.
What the Remedy Actually Looked Like
Across these cases, the pattern in how genuinely defective installations get remedied is consistent: full removal of the defective material and reinstallation, not incremental patching or re-coating. This matters because it's not a marketing claim from a removal contractor with an incentive to sell you the bigger job — it reflects how the material's actual defect mechanisms (off-ratio curing, trapped moisture, ongoing off-gassing) have been treated by parties with every incentive to argue for the cheaper fix if one existed.
Why This Makes Chemical Sense, Not Just Legal Sense
This isn't just a legal pattern — it lines up with the actual chemistry. Off-ratio spray foam has a different molecular structure than correctly-mixed foam; it isn't simply weaker foam that a topcoat or partial re-spray corrects. Spraying new, correctly-mixed foam over or around defective material doesn't fix the underlying adhesion failure or unreacted chemical content in the original job — it just adds a new layer on top of an unresolved problem. The litigation pattern and the chemistry point to the same conclusion independently, which is part of why it's worth taking seriously rather than dismissing as overly cautious.
What This Means If You're Dealing With a Suspected Problem
If a contractor is proposing a quick, inexpensive fix for symptoms that sound like off-ratio mixing (persistent odor, tackiness, shrinkage) or trapped moisture, it's worth asking directly how that fix addresses the underlying defective material — not just the visible symptom. A legitimate answer will explain removal scope, not just a surface treatment.
What This Doesn't Mean
To be precise: this doesn't mean every spray foam issue requires full removal. A small, genuinely isolated cosmetic defect in an otherwise correctly-cured installation is a different situation, and a targeted repair can be appropriate there. The distinction is whether the underlying installation is sound elsewhere — which is exactly what a real inspection is for, not something to assume either way without one.
