Founded by Barış Demir, Demir Mechanical & Construction grew out of years of hands-on experience across residential, commercial, and industrial projects in the Greater Toronto Area. We saw too many property owners let down by rushed work and unclear pricing — so we built a company that does the opposite.
Every installation and repair is done to code and built to last.
Upfront, honest pricing — what you need, not what pads the bill.
Fast response and systems that keep running long after we leave.
No guesswork and no surprises — here's what to expect when you call Demir Mechanical.
