If you own an older house in this city, you know the sound. That low whistle that shows up in the living room around late November and does not stop until April. For years I told myself it was charm. Character. The price of admission for living in a house with actual history instead of one of those new builds that all look like they were designed by the same algorithm.
Then I got my January gas bill last winter and the charm wore off real fast.
So this past year I finally did the thing I had been putting off since we bought the place: I dealt with the windows. Not just the obvious culprit in the kitchen that had a visible gap you could feel from across the room. All of them. And I figured I would share how that went, because I know a good chunk of you reading this are sitting in a similarly draughty Toronto house right now, nodding along.
The Diagnosis Phase
The first thing I did was the candle trick. You walk around the house with a lit candle near the window frames and watch where the flame flickers. Low tech, but it works shockingly well. By the time I was done I had basically every window in the house flagged as a problem, which was both validating and depressing in equal measure.
Turns out the original windows in a lot of these older Toronto homes are single or, if you got lucky at some point, double glazed at best, and after a few decades the seals are not doing what they used to. You are basically paying to heat the outdoors all winter and air condition it all summer. Not exactly a flex.
Down the Triple Glazed Rabbit Hole
Once I started looking into actually fixing this instead of just complaining about it on group chats, I went down the inevitable research rabbit hole and kept landing on triple glazed windows as the upgrade that actually makes a real difference in a climate like ours. Not just marginally better than what was already there, genuinely different in how the house feels.
The short version, for anyone who has not gone down this particular rabbit hole themselves: triple glazing means three panes of glass instead of two, with gas-filled gaps between each layer that act as insulation. More layers, more trapped air space, less heat escaping in winter and less heat coming in during the summer. It is not complicated physics, it is just more of the thing that already works with double glazing, done better.
I found a pretty solid breakdown of the benefits of triple glazed windows while I was researching, which laid out the energy efficiency case better than most of the contractor sales pitches I had been sitting through, and it actually matched what I was hearing independently from a couple of different installers. That was reassuring, because by that point I had heard enough conflicting opinions from various corners of the internet that I was starting to distrust the whole process.
The Part Nobody Tells You About
What surprised me was not the energy savings, though those have been real. It was the noise difference. We are not on a crazy busy street but there is enough traffic and enough neighbourhood activity that I had just sort of accepted a certain baseline hum as part of city living. After the new windows went in, that baseline dropped noticeably. My wife noticed before I did, actually, she mentioned it within the first week, before either of us had even really clocked the temperature difference.
The other thing nobody mentions is the cold spot effect. Even with the heat cranked, certain rooms in our old house always had that zone near the windows where it just felt colder, that little radius where you would not want to sit for too long in January. That is basically gone now. The whole room feels like one temperature instead of having this gradient from the window to the rest of the space.
Was It Worth It
Look, it is not a cheap project. Anyone who tells you replacing all the windows in an older Toronto house is a budget weekend job is lying to you or has a very different definition of budget than I do. But thinking about it as a one-time investment against fifteen winters of heating bills and the actual comfort of the house, it made a lot more sense than I initially wanted to admit.
I am not going to pretend I am some home renovation expert now, I very much am not, I just complained loudly enough about a drafty house that I eventually did something about it. But if you are in the same boat, sitting in an old Toronto house wondering if you are imagining how bad the windows actually are, you are probably not imagining it. The candle test does not lie.
Anyway, that is my exciting update from the world of home ownership. Stay warm out there, whatever stage of denial about your windows you are currently in.
