Do I need a permit to replace windows in Ontario?

Not usually for same-size replacements. You usually need one to enlarge an opening or create a new one. We confirm with your municipality.

Can a window be turned into a patio door?

Yes. The wall below the window is removed and, if the opening gets wider, a new lintel is installed. It is a common change at the back of the house.

Yes. We work throughout Vaughan, including Concord, Woodbridge, Maple, Thornhill and Kleinburg. Call +1 (647) 718-3913 to arrange a visit.

Who issues the permit for this work in Vaughan?

Where a permit is needed, it is issued by the City of Vaughan's building department. We prepare the drawings and handle the application and inspections.

Window and Door Replacement in Vaughan

New windows and doors change both how a house looks and how warm it stays. We replace existing units and, where the design calls for it, cut larger openings for more light. In Vaughan, most homes date from the 1980s onward: large detached houses in planned subdivisions, with estate properties around Kleinburg.

Before you start

What to know.

Permits
Replacing a window or door with one of the same size usually needs no building permit. Making an opening larger or adding a new one is a structural change and usually does.
Installation matters
Most drafts and leaks come from how a window is installed, not from the unit. Flashing, air sealing and insulation around the frame are what we pay attention to.
Windows near the lot line
Building Code limits the amount of glass on walls close to a neighbouring property, which can restrict new side windows.
