In reacting to a recent story (Aug. 12 in The Washington Post) about problems of consumers with home improvement contractors who abandoned ongoing jobs becuase of financial problems, Silver Spring resident Moses Voloshen responded on behalf of professional contractors.

As president of the area chapter of the National Home Improvement Council Inc., Voloshen stated: "I have lived through several recessions during my 25 years as a professional contractor. There's rough sailing for a while and employees may have to be laid off temporarily.

"But firms that blame their plight on economic conditions are, for the most part, using the downturn as an excuse. A consumer who does business with a well-established firm having a verifiable tract record is unlikely to encounter this problem or any other of a seriouis nature . . . A through investigation of the contractor's credentials should precede signing a detailed contract that the consumer understands."
