Jack Devetten – President


Jack began his plumbing career at the ripe age of 12 helping his father on weekends and school holidays. He always enjoyed working with tools and figuring out how to fix things. Completing a matriculation in high school Jack, went to the University of Calgary where he enrolled in engineering and minored in business.

To help pay the bills he did renovations on weekends and also started a “Disc Jockey” business that would provide music for parties, weddings and corporate events. After spending a year with his head in the books he realized that working and building things was much more agreeable then being tied to a desk so he decided to go back into plumbing and start a Plumbing and Gas-fitting apprenticeship.

This was 1982 and the big recession was about to change things again. As an apprentice the jobs were becoming scarce so in 1984 Jack enrolled into the Radio Broadcasting program at SAIT to have a back up plan until things in construction would pick up.

In 1987 Alberta began to build again and Jack went back on the tools full time and did Radio Announcing on the weekends. Not satisfied by working for regular wages, Jack jumped at the chance to start his own plumbing business when his current boss decided to retire to British Columbia. This was 1995, and at age 31 Jack believed he was indestructible. He quickly grew Simcor Plumbing from 2 employees to 8 trucks with 14 employees and 4 subtractors in 3 years.

Exponential growth and no systems in place to track and control the costs. He re-mortgaged the home twice and worked more hours just to keep all the balls in the air. When his wife said fix this or I’m out of here he knew he had to change but had no one to turn too. Being a quarter of a million in debt and the possibility of losing everything, house, business, marriage he began a quest of learning the basics of running a profitable business.

Jack hired consultants which gave him the first edition of the business systems that work for a construction company, such as billing quickly, estimating accurately and tracking labour costs. This began to stop the money leaks and put Simcor Plumbing on the path to breaking even. Also saving his marriage and home. It was still a gruelling 60+hour work week, 10 to 12 hours a day Monday to Friday with 6 to 8 hours on Saturday.

Being young gives resilience. One of the consultants remarked that a service company is less risk because you have many customers paying for smaller jobs so if someone doesn’t pay, you wont go bankrupt. He was in a court battle at the time with one of the builders who owed $68000 so the risk to the home was still over his head. This was the best Idea they gave him, just a nonchalant comment while having lunch. Jack remembered this Idea and kept thinking on how he could change his construction company into a service company, again alone, a good idea but no instruction on how to do it.

Then he read an article in HPAC magazine about a contractor group specializing in Plumbing Service and had a proven formula for success. He contacted Darrel Yashinsky who invited Jack to attend a profit day in Calgary. He saw the business systems that were demonstrated and knew he found what he was looking for, now not alone because Darrel a former contractor himself would coach him in how to implement the systems for success and now Jack could promise his wife a timeline for when they could be financial well off with lots of time for the family and traveling. So the timing was a little off, but in 2010 they achieved all of their goals. 

Jack and his lovely wife of 30 years have a micro ranch overlooking the beautiful Rocky Mountains including a barn, indoor dressage arena and an outdoor driving arena with purebred world renown Friesian horses, a classic sports car and a luxurious home with in-floor heating throughout. Also a huge Quonset (Toy Barn) where they park the quad, motor home and motor sailing yacht, and wood working tools. The best thing of all, Jack takes every Wednesday off to spend with Margaret at the ranch enjoying the country life, and the working days are usually 6 to 8 hours a day making it at most a 32 hour work week.

The business systems are working well and are constantly being improved so that they are fun, easy and efficient.
