Herrin Enterprises invented the Bio-Shield Method, the affordable, green cleaning method for workplace infection control. The company is also the exclusive distributor for the BioShield 75 long-term antimicrobial preventative in New England and New York.

Since opening our doors in 1985, we’ve grown from a husband-and-wife home-and-office-cleaning company, to a company large enough to serve not only Upper Valley homeowners but also some of the Valley’s largest facilities. We work closely with all our customers to provide the highest-quality deep-cleaning possible. We believe that your home or office isn't just a reflection on you; it's also a reflection on us. We’re your neighbors – not a chain – and we’re active in the Upper Valley community.
