Windows Markham

Whether you have a new home in Markham, or renovation project in Thornhill, we can provide both the product and service you need. We can turn a sliding glass door into a window, turn a window into a sliding glass door, give you a door or window in a wall that doesn’t have one now, all this in addition to the standard retrofit installation.

Doors Markham

There’s more to replacing your existing entry door than just hanging a new door in an old jamb or settling for a pre-built, off the shelf door from a home center. With a new entry system from WELDA you get a complete entry door system with a variety of options allowing you to create a unique entrance to your Markham home that combines the best low maintenance and energy efficiency features available.
