A southwest Florida couple who complained about corrosive gas leaks will wait to file a lawsuit against two U.S. drywall companies after one of them came forward and offered to inspect their home, their attorney said Monday.

Brenda and George Brincku, who live near Fort Myers, claim they have experienced the same problem bedeviling homes built in 2006 with Chinese drywall even though they built with an American-made product. They claim their air conditioning components, electrical wiring and metal objects in the home have corroded because of sulphur gas discharged by wallboard that is not 100-percent gypsum.
