CertainTeed survey finds 65 percent of homeowners worried about mold health risks.

VALLEY FORGE, Pa. - One in four Americans has experienced mold in their home or knows someone who has.

That's according to a national survey of 1,040 people released by CertainTeed Corp. and conducted by Opinion Research Corp. According to the survey, 55 percent of those asked are concerned about mold in their homes.

"Mold has been around forever, but in the past few years it has emerged as a financial and health problem for homeowners because increased numbers of people are getting sick, from nosebleeds to seizures to respiratory ailments to memory loss," said Glenn Singer, manager of building sciences for CertainTeed's Insulation Group.

When participants in the survey were asked about their largest concern regarding mold in the home, 65 percent said they were worried it was a health risk to themselves or their families. Thirty-one percent said they were concerned about the expense of removing mold from their homes.

The survey also found that 56 percent of the participants would call a mold-remediation expert to deal with the problem, while 34 percent said they would try to clean it themselves.

Forty-eight percent of respondents said they would sue a builder, previous owner or property owner if they found mold in the walls of their own home.
