Window glass replacement · Ottawa & Gatineau
When a pane cracks or fogs up, you usually do not need a whole new window. CGR Window Glass Replacement & Repair replaces the glass itself — sealed thermos units, cracked panes, and patio door glass — while your existing frames and trim stay in place. We serve Ottawa, Nepean, Kanata, Orleans, Barrhaven, Gloucester, and Gatineau with free at-home measurements.
Glass replacement, frame kept
If the glass in your window has cracked or fogged up, you may not need a full window replacement. Book a free measurement or call us to discuss replacing the glass while keeping a sound window frame.
In most modern windows the glass is a separate sealed unit that sits inside the sash — it is not fused to the frame. When that unit cracks or its seal fails, it can be removed and a new one custom-made to the exact same dimensions and thickness. Your frame, trim, and interior finish stay untouched, and you avoid the largest costs of a full window replacement: the new frame, the installation labour, and the finishing work around the opening.
We replace sealed insulated units (thermos glass) in double and triple pane windows, cracked or broken panes, glass in sliding patio doors including large tempered units, and single panes in older windows. If the glass is fine but the window will not crank, lock, or slide properly, we also repair window hardware. And if it is only the screen mesh that is damaged, our mobile screen repair service covers that separately.
Book online or call us. A CGR technician comes to your home in Ottawa or Gatineau, measures the exact glass dimensions and thickness, checks the spacer and the condition of the frame, and confirms access. You receive a clear quote before any glass is ordered. Once you approve, the new unit is custom manufactured and installed on a second visit — typically under an hour per window, with no wall or trim work.
We will be honest: glass-only replacement is not always the right answer. If the frame is rotten, warped, or water-damaged, or you want to change the style, size, or energy performance of the entire window, a full replacement from a window installer is the better investment. We tell you exactly that at the measurement visit — we do not sell complete windows, so there is nothing for us to upsell.
We replace window glass across Ottawa and the surrounding communities: Nepean, Kanata, Stittsville, Orleans, Gloucester, Barrhaven, and Manotick, plus Gatineau, Hull, and Aylmer on the Quebec side. Service is available in English and in French.
Both fix a failed pane — but they solve different problems at very different price points. Here is the honest comparison.
| Glass-only replacement (what we do) | Full window replacement | |
|---|---|---|
| What gets replaced | Only the glass unit inside your sash | The entire window: frame, sash, glass, and trim |
| Your frames and trim | Stay in place, untouched | Removed and rebuilt |
| Typical cost | A fraction of the cost of a new window | Significantly higher: new window, labour, and finishing |
| Time in your home | Usually under an hour per window | Half a day or more per window, plus finishing work |
| The right choice when | The frame is sound and only the glass has failed | Frames are rotten or damaged, or you want a new window style |
Not sure which one you need? That is exactly what the free measurement visit answers. If your frame is not worth saving, we will tell you.
Yes. In most modern windows the two panes come as a single sealed unit, so we replace that full unit rather than one sheet of glass — that is what restores the insulation. In older single-pane windows, we can replace the individual pane.
No. We replace glass, thermos units, hardware, and screens. If your frame is beyond saving, we will say so at the free measurement, and you can go to a window installer knowing exactly what you need.
It depends on the size of the unit, the glass type and thickness, whether tempered glass is required, and access. It is almost always far below the cost of a full window replacement. You receive an exact quote after the free measurement, before any glass is ordered.
Yes. Every sealed unit is custom manufactured to your window's exact dimensions, thickness, and spacer type, so it fits your existing sash precisely.
