About Aggie Plumbing – A Family-Owned Fort Collins Plumbing Company
Aggie Plumbing & Service was started in 2008 with Craig Unter and a pickup truck. Craig’s vision was to open a plumbing service company that was different from the other bigger companies in Northern Colorado. He took the knowledge he learned from working for previous companies and decided to design a company that was focused on customer service, rather than maximizing profit. His commitment to honesty, reliability, and quality workmanship quickly built a loyal customer base, proving that a people-first approach to business leads to long-term success.


Over time, Aggie Plumbing expanded into new construction plumbing in both residential and commercial buildings. Projects have included fire stations, medical offices, restaurants, salons, and government buildings and remodels. Aggie Plumbing has hired and retained some of the most knowledgeable and talented plumbers in the field. Our licensed plumbers have over 75 years combined experience with Aggie. We take care of our employees, so they feel empowered to take care of our customers and clients. By fostering a team of skilled professionals who take pride in their craft, we continue to deliver exceptional plumbing solutions that stand the test of time.
Our Plumbing Team

Craig Unter, Owner/President
Craig started plumbing in 1993 as an apprentice plumber for a large well-known plumbing company. He worked his way through service, new residential construction and large commercial projects including schools, hotels, and multi-unit buildings. He was able to obtain his Residential, Journeyman and Master plumbing license during this time. After several years of working for these large well known plumbing companies he decided to start Aggie Plumbing.
Being a longtime Fort Collins resident and a Colorado State alumni and avid Ram fan, he and his wife, Melissa decided that the “Aggie” name would be a good fit for a local plumbing company. And so, Aggie Plumbing & Service was born. In his free time Craig enjoys all that Fort Collins, Colorado has to offer including skiing, hiking, hanging with his family including their two energetic australian shepherds. You might find him socializing at a brewery or attending CSU football or basketball games with family and friends.
