Precision
Scoping effort up front and quoting accuracy as a point of pride: it’s what makes our 10% price guarantee possible.
About & Team
Built on relationships. Measured in inches.
SquareInch Contracting is a Toronto commercial contractor built for one kind of client: property teams who need work done right, in buildings that never stop working.
Our mission
To be the most trusted contracting partner in the GTA, measured by repeat business, not project count.
The name is our operating standard. A building is thousands of square feet, but it is built, and judged, one square inch at a time: the reveal on a millwork joint, the line of a ceiling grid, the closeout binder that’s actually complete. Nothing is too small to matter, and nothing is delivered unmeasured.
We believe the GTA’s property owners and managers deserve a contractor that behaves like an extension of their own team: transparent about money, honest about schedules, and accountable without being chased.
That belief has a track record: zero lawsuits, disputes or insurance incidents in our history, plus a price guarantee no one else in the market offers.
What we stand on
Presence
Ownership personally walks every active site weekly. Zero lawsuits, disputes or insurance incidents. Ever.
Pace
Weekends, holidays and late nights to hit turnaround times, never by compromising quality.
Meet the team
Principals on every project, not just on the proposal.
Seyfettin Yilmaz
Owner & Principal
Seyfettin leads every project from pricing through closeout. He has spent his career building commercial space across the GTA, and his standard is the company’s standard: measured, clean, finished right. When SquareInch prices a job, Seyfettin has walked it; when it’s handed over, he has walked it again.
Ido Nivron
Partner, Business Development
Ido is your first call and single point of contact. He works with property owners and managers to scope, plan and structure engagements that fit portfolio needs, then stays accountable for the relationship long after the project closes. If something needs attention, Ido picks up the phone.
Behind us: a vetted bench of long-tenured trade partners who work to SquareInch standards on every site.
