Double Check Builders, Inc. is a family-owned and -operated home improvement business, originally founded by Morton Ilberman in 1958. Morton took Joe Walker on as an apprentice in the early 1980s. After Morton lost his battle with cancer in 1989, Joe took over as the owner and operator of Double Check Builders. In 2007 his son Matthew became part of the team and now he, together with Joe, handles all the daily operations.
