Fog between the panes means the seal on your sealed unit has failed. In Outremont, the large windows of stone and brick homes, often old, fog up over time.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, with custom glass that preserves the building's character.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Outremont: sealed units for homes on the slopes of Mount Royal
Set against the north slope of Mount Royal, Outremont brings together large greystone homes, row houses and well-kept plexes, mostly built in the first half of the 20th century. Between Laurier Avenue, Bernard Avenue and Côte-Sainte-Catherine Road, facades feature casement windows, bay windows and transoms, while French doors at the back open onto gardens or terraces shaded by mature trees.
On the sloping streets closer to the mountain, mature trees keep some facades shaded and damp. That's when you need to tell two things apart: condensation on the inside surface of the glass, caused by indoor humidity, and fog trapped between the two panes, which means the seal has failed. Only the second calls for a replacement. We then offer a unit with Low-E and argon, and tempered glass for French doors.
In a bay window, each glass panel has its own dimensions, so we measure every unit separately during the free assessment. Residential streets are quiet, but parking is often regulated; a spot in front of the house makes it easier to carry large units. If your home is semi-detached or in a row, plan for inside access to the back windows. We work weekdays and Saturdays.

Water beads on the windows of my Outremont home in winter. Is the thermos broken?
Wipe the glass on the inside. If the moisture disappears, it's condensation from indoor humidity, not a failure. If it stays or leaves marks between the two panes, the seal has failed and the unit needs to be replaced.
Can you replace the glass in a bay window?
Yes, as long as each panel holds a sealed unit. Since sizes vary from one panel to the next, every unit is measured separately, custom-made within 24 to 72 hours and installed in the bay window's existing frame.
