About Us
The Door and Window Team Buttonville, Markham Calls Back
The measure of a contractor is not the first job, it is whether anyone calls them for the second. Windows & Doors Markham has built its work across Buttonville, Markham almost entirely on repeat customers and their neighbours, covering door repair, window installation, glazing, and locksmith services.
That only works if the price is fair, the timing is honest, and the work still looks right a year later.
Judged on Repeat Work
Most of our calendar comes from people who have used us before. That sets the standard.
Honest Timing
If a part takes three days to arrive, we say three days. Optimistic dates help nobody.
Fair, Fixed Rates
Priced by the job, not by how urgent it sounded when you rang.
Workmanship on Record
Every install is documented and guaranteed, with the details left with you.
