From Century Homes in the Annex to Condo Towers Downtown: Window Replacement in Toronto

Why Toronto Homeowners Choose Stone River

We supply, install, warranty, and service every window ourselves, so there’s one company to call later, not three. Our own fleet of tractor-trailers delivers directly to the job site rather than relying on a third-party carrier’s schedule. Free consultations are available at our Toronto Planning Studio or our Oshawa Showroom.

Permits and Building Type in Toronto

The City of Toronto only waives a building permit for window replacement in a detached house, semi-detached house, or row house with a single dwelling unit, and only if the opening’s size, location, and structural support stay unchanged. Replace a window in any other type of building, including a condominium or apartment building, and a permit is required.

Condo owners also need written approval from their condominium corporation before any window work, since the building envelope is a shared element. We work with houses, semis, and row houses across Toronto, and can help homeowners understand which side of that line their project falls on.

Signs It’s Time for Window Replacement

Heating bills climbing every winter with no clear reason. Condensation trapped between the panes rather than on the surface. Windows that stick, won’t stay open, or need force to latch. A noticeable increase in street or traffic noise coming through, common in denser Toronto neighbourhoods.

Getting the Most Out of Your New Windows

Check weep holes for debris each spring. Test locks and operators before the first cold snap. Have any condensation between panes looked at promptly, since it usually means a failed seal. Stone River also provides repair and maintenance service beyond the warranty period.

Frequently Asked Questions

Do I need a permit to replace windows in my Toronto home?

Not if you own a detached, semi-detached, or row house and the new window is the same size, in the same location, with no structural changes. Other building types, including condos and apartment buildings, require a permit.

Do condo owners need board approval to replace windows?

Yes. The window and building envelope are typically a shared element, so approval from the condominium corporation is needed in addition to any permit.

What affects the cost of a window replacement project?

The number of openings, size and style, product line, and whether the opening needs any adjustment. A free consultation covers these specifics for your home.

How long does window replacement take?

Most residential projects finish within a day or two, depending on the number of windows.

Do you service windows after the warranty ends?

Yes. We offer post-warranty repair and maintenance service.

Which brands do you install in Toronto?

Andersen, Dashwood, and Therma-Tru for entry and patio doors.
