Our History

Serving our communities with pride in workmanship.

As a plumbing and heating company, we're proud to continue serving our communities with the same pride in workmanship and industry leading customer service that my grandfather did. We live here and work here, and we are honoured to be your local plumbing and heating service provider.

"A competitor quoted $8,000 for an entire system replacement. VanDiermen diagnosed the actual broken component and fixed it cleanly for $800."

40+ Years of Honest Trade Service

Grandpa Aart's original service truck from the 1980s. The family motto has remained identical for three generations: honesty first.

3 Generations Founded in 1980s
True Story: Diagnostic Integrity
"After our AC stopped cooling during a summer heatwave, another company told us the entire system was shot and had to be replaced for about $8,000. It felt dishonest, so we called VanDiermen & Sons. Shayne came out right away, diagnosed the specific failed electrical component, ordered the part, and fixed our original AC for $800. It ran like new."
