How serious is spray foam insulation litigation?

More serious than most contractors realize. At least 13 lawsuits have been filed since 2012 across Florida, Connecticut, Michigan, New Jersey, New York, Pennsylvania, and Wisconsin alleging improperly cured spray polyurethane foam continues emitting amines and isocyanates after installation, causing headaches, respiratory symptoms, and forcing families to abandon or remediate their homes. In one Texas case, a San Saba jury awarded a family $1,004,528 in February 2018, including $200,000 for mental anguish, after chemical contamination forced them to vacate, live in a trailer, and ultimately bulldoze the entire house.

Does insurance cover mold claims from a bad vapor barrier?

Not reliably. Mold litigation in this trade commonly traces back to vapor barrier installation defects, even a small rip or tear negates the barrier and traps moisture against framing or slab. Insurers frequently deny these claims by classifying them as "damage to the contractor's own defective work" rather than a covered loss, which is exactly the kind of coverage gap worth understanding before, not after, a claim.

How bad is drywall sanding dust exposure really?

Worse than commonly assumed. A NIOSH Health Hazard Evaluation found drywall sanders exposed to total dust levels up to 10 times OSHA's permissible exposure limit, exceeding both the 15 mg/m³ total-dust limit and the 5 mg/m³ respirable-dust limit. Drywall and joint-compound sanding is often wrongly assumed to be exempt from the stricter controls under OSHA's 2016 silica rule, it isn't automatically exempt, and the exposure data backs that up.

What licensing applies to drywall and insulation work?

There's no uniform national standard, licensing is largely handled at the city or county level in most states rather than statewide. Where state bonds do exist for general specialty contractors, they commonly run $10,000 to $25,000, comparable to bonding requirements in masonry and painting.
