Our story
One van, one rule: tell people the price first.
Dan Kowalski spent fifteen years working for large plumbing outfits where technicians were paid on commission and customers found out the price when the bill arrived. In 2004 he bought a used van and started doing it differently.
Today Copperline has fourteen licensed plumbers and a dispatch team that never sends a call to voicemail. Our technicians are still paid hourly, and every job still starts with a written price.
We are proud to live and work along the Front Range, and to be the plumber that neighbors pass along to each other.
