Filco Company, Inc., originated in 1980 as a sole proprietorship and incorporated in 1990. Originally Filco Company, Inc., started its business by working with Homeowners, Realtors, Mortgage Companies, Inspection Companies, etc., and assisting them in providing home repair services to aid them in the sale of residential homes and commercial buildings. In 1994 we began acquiring jobs to decommission abandoned residential heating oil tanks. As the request increased, by 1995 Filco Company, Inc., decided to focus strictly on decommissioning heating oil tanks and provide environmental services.
