Window Repair Vaughan
Same-Day GTA Dispatch
Vaughan runs about 16% colder than downtown Toronto, and its 1980s-90s sealed units are failing. We swap the glass, not the frame. Free photo quote.
What to do while you wait.
Keep children, pets, and anyone without proper footwear away from the broken glass. Shards can scatter several feet from the break point.
Glass still attached to the frame can fall without warning and cause deep cuts. Leave loose pieces alone until our technician arrives.
If you must walk near the area, wear closed-toe shoes and work gloves. Thin slippers or bare feet are a serious hazard.
Use a heavy tarp, thick cardboard, or plastic sheeting secured with tape to block wind, rain, and debris until we arrive.
Take photos of the damage from both inside and outside. These help our technician prepare the right glass size and type before arriving.
Call 647-803-2730. Our emergency line is staffed 24/7 including nights, weekends, and holidays.
Overview
Vaughan's glass problems follow its building boom. The city had 15,957 residents in 1960 and 323,103 in 2021, and it was the fastest-growing municipality in Canada between 1996 and 2006, when its population rose 80.2%. Most homes here are suburban houses from the 1970s to the 2000s, fitted with factory-sealed double-pane units that are now reaching the end of their seal life. About 63% of Vaughan's dwellings are single-detached houses, and apartments of five or more storeys rose 40%, from 9,805 to 13,750 units, between 2016 and 2021.
So the typical Vaughan call is a fogged sealed unit, a tired patio door or a stripped casement crank, plus the odd older window in the Kleinburg or Thornhill village cores. OhMyGlass Window and Door Repairs replaces the sealed unit or pane in the frame you already have, and fixes worn cranks, hinges and patio-door rollers on the same visit so you are not paying twice. If a frame has failed, we will tell you that is a window-replacement job rather than a glass repair.
Vaughan's climate is harder on glass than downtown's. Building-code climate data puts Woodbridge at 4,100 heating degree-days against 3,520 at Toronto City Hall, roughly 16% more heating demand. That shows up as more condensation on the room side, because the colder the outside pane the less indoor humidity a window can hold before it sweats, and as more thermal-stress cracks, because on a cold sunny morning the centre of a pane can warm to 15 to 25 °C while the edge in the frame stays at −10 °C or colder. Summer matters too: sealants are six to eight times more permeable at 60 °C than at 20 °C, so the south- and west-facing units on Vaughan's big-lot houses often fog first.
Send a photo and rough measurements and we will tell you whether a glass-only repair will do, and give you a written quote before anything is ordered.
What tends to fail, by part of Vaughan
Woodbridge took spillover growth from Metro Toronto from the 1950s and reached Highway 27 by the early 1990s; Maple's big expansion ran from 1993 to 2000; Concord is mainly the industrial district, with homes in Glen Shields, Dufferin Hill and older Carrville.
original double-pane sealed units, casement and slider windows and sliding patio doors. Fogged units past a typical 10 to 25 year life, plus worn rollers and cranks.
vinyl windows and larger picture units, now showing first seal failures and thermal cracks in big south-facing panes.
older wood windows, some single glazing, with broken panes, putty and sash wear. Kleinburg dates from 1848 and keeps its core under the Kleinburg-Nashville Heritage Conservation District.
window wall and balcony doors. Early window-wall systems had sealed units that often fogged after only a few years of service before requirements were tightened.
commercial and warehouse glass sits alongside residential work here, at storefront glass repair.
Permits, heritage districts and condo rules in Vaughan
Replacing a sealed unit inside an existing frame does not touch the opening. Anything beyond that is worth a phone call first. General information, not legal advice.
the City of Vaughan has a dedicated building-permit page for door and window openings. Creating or enlarging an opening generally changes the structure, so check that page or call Building Standards before you start.
Kleinburg-Nashville, the Village of Maple, Thornhill-Vaughan and a Woodbridge Heritage District. We could not confirm from the City's page whether window repair or replacement needs a heritage permit, so call Vaughan's heritage staff before replacing visible windows.
it sits on the Vaughan-Markham boundary, so which heritage rules apply depends on which side of the line you are on.

Ontario's default is that the corporation repairs common elements and owners repair their units, but a declaration can change the split, and windows are often common elements. Talk to management first.

Frequently asked questions: Vaughan window repair
Do I need a permit to replace a window in Vaughan?
It depends on the work. The City of Vaughan has a dedicated building-permit page for door and window openings, and creating or enlarging an opening generally changes the structure, so check that page or call Building Standards before you start. Swapping a fogged sealed unit inside an existing frame does not change the opening at all. If your home is in one of Vaughan's four heritage districts, check heritage rules separately.
Why do windows in my 1990s Woodbridge house keep fogging up?
Fog between the panes means the sealed unit's edge seal has failed and moist air has got in. Typical sealed-unit life is about 10 to 25 years, and a lot of Woodbridge, Maple and Concord housing was built in the 1980s and 1990s, so many original units are past that range. The fix is a new sealed unit; the frame can usually stay.
Is condensation on the inside of my windows a Vaughan problem?
Partly. Woodbridge is rated at 4,100 heating degree-days against 3,520 downtown, and the colder it is outside, the lower the indoor humidity a window can tolerate before it condenses. Keep winter humidity toward the low end of Health Canada's 30 to 50% range, run bath and kitchen fans, and open blinds so warm air reaches the glass.
Who fixes a broken window in a Vaughan condo?
Under Ontario's default rules the condo corporation repairs common elements and owners repair their units, but each building's declaration can change that, and windows are often common elements. Check your declaration and call management before booking a repair. This is general information, not legal advice.
Can you fix the patio door as well as the glass?
Yes. Worn rollers, cranks and hinges are replaceable parts, and we fix them on the same visit as the glass so you are not paying for two trips.
Guides for this job
Local guide
Where the frame is sound, a fogged or broken window is fixed with a new sealed unit in the existing frame. One GTA contractor lists glass-only replacement at $350–650 per opening, against $1,000–1,800 for a full-frame window.
Vaughan grew from 15,957 people in 1960 to 323,103 in 2021, so nearly all of its housing is post-1960 suburban stock with factory-sealed double-pane units.
Single-detached houses make up about 63% of Vaughan's dwellings, but apartments of 5+ storeys grew 40% between 2016 and 2021 as towers rose in places like the Vaughan Metropolitan Centre.
