Castle Plumbing & Heating was founded in 1982 by Henry Janzen. He had run the family business Janzen Plumbing & Heating since 1969, but decided it was time to head out on his own.
Today, the business is headed by his son Kasey. Henry is still here, making sure everything runs smoothly.
Our family run business has 25 full time employees. We work on projects ranging from repair work to multi million dollar seniors complexes and commercial developments.
