Ottawa Plumbing and Heating has proudly served the National Capital Region for over a century. First opening in the early 1900s, we worked on some of Ottawa’s first indoor plumbing and heating systems.


Although a considerable amount of time has passed, our commitment remains the same: Offer expert consultation, deliver exceptional mechanical services, and treat every home with the care we’d wish upon our own.
