Streetsville, “The Village in the City”: old brick, main-street glass, newer homes
Streetsville has three kinds of building close together: early brick houses, Queen Street shops with wide glass fronts, and newer subdivisions around the old core. Each is a different window job. Tell us which one you have and what is wrong. We connect you with an independent local glass professional who does that work, and the pro measures, quotes and does the job.

A village since 1819
Streetsville was opened for settlement in 1819 and joined Mississauga in 1974. Timothy Street's house from 1825 is described as one of the oldest brick houses in Peel Region.
That matters for windows. Very few Mississauga homes are older than the 1960s, and Streetsville's core is one of the places where they are. A house here may have had its windows changed several times, or not at all. Before anyone quotes, it helps to know what is in the openings now: original wood sash, wood windows with storms added, or later replacement units. A photo of the whole window and a close-up of a bottom corner usually tells a pro.
Queen Street storefronts
On Queen Street, the historic main street, shopfront glass below and ordinary windows above are separate jobs, sometimes for separate pros.
If a shop window breaks, keep people away from the glass, take photos for your insurer, and have the opening covered. A shopfront pane is made to measure, so the cover goes on first and the glass follows. If you lease the unit, your lease says who arranges the glass. Our storefront glass page lists what a pro needs.
Older homes: wood windows and storms
Some older Streetsville houses still have wood windows, sometimes with storms outside. A sticking sash, a cracked pane, loose putty or a broken sash cord is a repair, not a reason for a new window. A pro can replace one pane or reglaze a sash and leave the frame alone.
Replacement makes sense when the wood is soft right through or the frame has moved out of square. Even then you can choose a new wood window made to match or a different material, so ask the pro to price both. Our guide on repairing the glass or replacing the window sets out how to decide.
Newer subdivisions: fogged units and patio doors
The newer streets around the core have everyday problems:
- Foggy sealed units: fog or a white film between the panes means the window seal has failed. The glass unit, which pros call a sealed unit, can usually be replaced in the same frame.
- Sliding patio doors: a door that drags, won't lock or lets water in at the sill often needs rollers, a lock or new caulking before it needs replacing.
- Cranks and screens: a casement that won't close may only need a new crank, and a torn screen can be rescreened.
Heritage status: check before you change
Streetsville is not one of Mississauga's two heritage conservation districts, Old Port Credit Village and Meadowvale Village, whose rules are in our heritage village windows guide. Those rules do not cover Queen Street.
A single house can still be protected: under the Ontario Heritage Act it can be listed on the City's heritage register or designated on its own. Ontario has given municipalities until 1 January 2027 to decide whether to designate listed properties.
Before you change original windows or doors:
- Look up your address in the City's heritage properties list.
- If it appears, contact City heritage planning before booking work.
- Tell the pro what you found, so the quote fits the rules.
Designated? Check whether the City's heritage property grant is open and covers windows.
Streetsville questions
Is Streetsville a heritage district?
No. Mississauga's two heritage conservation districts are Old Port Credit Village and Meadowvale Village, and their window rules do not apply here. An individual Streetsville house can still be listed or designated, which can limit what you change. Look up your address on the City's heritage list before replacing original windows, and tell the pro what you find.
Can the old wood windows in a Streetsville house be repaired rather than replaced?
Often, yes. A sticking sash, a cracked pane, loose putty and a broken sash cord are all repairs. The frame and sash stay, and only the worn part is replaced. New windows are worth pricing when the wood is soft right through or the frame has shifted badly. Send a photo of the whole window and a close-up of the bottom corner of the sash. Window repair explains the smaller fixes.
Do you handle storefront glass on Queen Street?
Yes. We pass storefront requests to independent pros who do commercial glass, from cracked shop windows to glass doors and the windows upstairs. We can't promise a pro is free the same day, but we pass your request on and follow up so it doesn't go quiet. Send photos, the rough size of the pane and whether the opening is covered.
The windows in my newer Streetsville house have fogged. Do the frames have to go too?
Usually not. Fog between the panes means the sealed unit has lost its seal. If the frame is sound, the pro orders a new sealed unit to the same size and fits it in the existing frame. Some pros offer defogging, which cleans the space between the panes; ask what it does for the seal. A new window makes sense when the frame is failing too. The foggy window page compares the options.
