NEW ORLEANS (AP) - A Chinese drywall manufacturer, suppliers, builders and insurers have agreed to repair homes in four states under an agreement to fix homes damaged by corrosion-causing drywall.

U.S. District Judge Eldon Fallon expressed optimism that Thursday's deal could resolve most of the property damage claims against Knauf Plasterboard Tianjin Co. Fallon is presiding over the consolidated claims against Chinese drywall makers.

Lawyers say up to 300 homeowners in Florida, Louisiana, Alabama and Mississippi whose homes had drywall manufactured by KPT will get their homes fixed under the agreement.

Knauf has been accused of selling drywall that causes corrosion inside homes.
