What actually happens to my old windows after they haul them away?

Great question — most homeowners never think about this, and the answer is more interesting than you'd expect.

The short answer is: it depends on the material, condition, and which company removes them. There's no single universal process, but here's what typically happens to the different components.

Vinyl windows (the most common type replaced in Ottawa) are technically recyclable, but the reality is mixed. Vinyl (PVC) can be ground down and reprocessed into new products like fencing, decking, or lower-grade window profiles. However, not every recycling facility in Ottawa accepts mixed PVC window frames, so some contractors end up sending them to landfill. If this matters to you, it's worth asking your installer directly whether they have a recycling arrangement with a facility that accepts vinyl.

Glass is where it gets complicated. Window glass is not the same as bottle glass — it has coatings (like Low-E), gas fills (argon), and laminated or tempered layers that make it difficult to recycle through standard streams. Most old window glass, especially double or triple-pane sealed units, ends up in landfill. Some specialty glass recyclers exist, but they're not widely used in the residential replacement market.

Aluminum and wood frames have better recycling outcomes. Aluminum is highly recyclable and retains value as scrap metal, so aluminum-framed windows are often stripped and sold to metal recyclers. Old wood windows, if they're in decent shape, sometimes get salvaged — architectural salvage shops in the Ottawa area occasionally take them, and some homeowners donate them through platforms like Facebook Marketplace before replacement day.

In Ottawa specifically, some installers partner with waste haulers who sort materials at a transfer station rather than sending everything to a single bin. If environmental disposal is important to you, ask your installer upfront about their waste handling process — a reputable company should be able to give you a straight answer.

If you want to ensure your old windows are handled responsibly, you can also ask to keep them for a day or two before removal to list usable ones for salvage pickup.
