LEE COUNTY, Fla. - Officials with the Consumer Product Safety Commission are investigating an Alva family's claim that the drywall in their home may be defective.

George and Brenda Brinku believe the drywall is American-made.  They say they bought it several years ago from National Gypsum.

"The only thing I can label this as is a disaster," George Brinku told WINK News.

The couple says they've been forced to rent another home for the last 18 months, ever since they began to suspect something was wrong with the drywall in their two-story home.

"The evidence is overwhelming," George said.  "You look around the home and see it."

The home does exhibit some of the tell-tale signs of tainted drywall.  There are blackened copper wires and coils in the house, spotted bathroom fixtures, and the sulfur-life smell.

The Brinkus sent a sample of their drywall to the Mass. Institute of Technology.

"We told them,  'Hey, could you do some testing'," Brenda Brinku said.  "They tested it and said it's like acid rain in our house."

The couple also began having headaches and feeling ill.  For the safety of their son, they soon moved out.

Wednesday, officials with the CPSC began a detailed study of the Brinku's home.   A spokesperson says that while experts will look at the drywall, there could be other reasons for the corrosion and smell in the home.

Calls to National Gypsum on Wednesday were not returned.  The company has previously said it does not supply defective Chinese drywall to customers.  The company has also tested the Brinku's wallboard and does not believe it is the source of the home's problems.

The Brinkus say they are pursuing legal action against the company, and will fight for better oversight of drywall manufacturers in America.

"We want to know what's in it, how it's made, and what it's composed of," George said.  "Then we need to fix the problem, find out what we did wrong, and move on."
