Work out what your windows really need — and record every opening once

Window Ottawa starts with the symptom (fog between panes, condensation, drafts) and explains what it usually means, then helps you record every window and door opening once, so every quote prices the same thing.

What result should I expect?

A plain explanation of your symptom and an opening schedule (room, width, height, style, flags like bedroom egress or water damage) with a planning range. Ordering sizes and site conditions still need an in-person check — it is not a quote.

How do I save, share or get help?

Download Window Project File keeps the schedule on your phone. Continue with HomeUpgraders sends it to us when you are ready. Compare pane types explains glass options.

If something goes wrong
  • Fog is between the panes. That is a failed seal in the glass unit — often the glass unit alone can be replaced, not the whole window.
