Robert Hartwig, president of the Insurance Information Institute, agreed that homeowners policies were never meant to cover "faulty, inadequate or defective" workmanship, construction or materials.
Tom Zutell, spokesman for the Florida Office of Insurance Regulation, said the cancellations are troubling, but legal. No law prevents insurance companies from canceling policies because of Chinese drywall.
"We are staying out of the fray at the moment," he said.
Even if a homeowner does not file a claim over the drywall and remains covered, they could later be denied a claim for a fire or another calamity if insurance investigators determine the home contained undisclosed Chinese drywall.
"If you think that by not telling your insurance company about the drywall that you're protected, you're sadly mistaken," Durkee said.
Interesting question here though, "workmanship, construction". I mean that could be applied to almost any issue that arises with home couldn''t it?
