Fog between the panes means the seal on your sealed unit has failed. In Pierrefonds-Roxboro, the large windows of bungalows built in the second half of the 20th century are now reaching the end of their life.
Good news: replacing the whole window is rarely necessary. We replace only the faulty sealed unit within the existing frame, with custom glass.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Pierrefonds-Roxboro: sealed units for homes near the river
Along the Rivière des Prairies, Pierrefonds-Roxboro grew mainly as a residential suburb of bungalows, split-levels, cottages and semi-detached homes, with a few condo buildings near the main roads. Split-levels have windows on several levels, including half-buried basement windows. Large living-room windows and sliding patio doors onto the backyard are standard throughout the borough, from Roxboro to the western edge of Pierrefonds.
Being close to the river and natural areas like Cap-Saint-Jacques Nature Park keeps the air damp much of the year. Basement windows, cooler and closer to the ground, are often the first to fog up between the panes. We replace them with double glazing, argon and Low-E, which keeps the inner pane warmer and cuts down on condensation. Patio doors get a tempered-glass unit.
Lots are generally large and a private driveway means we can park close to the house. For basement windows, clear the window well outside (snow, leaves) and the space inside in front of the window. In spring, when the water rises near the river, it's best to book the visit once the area is clear. Travel is free Monday to Saturday, including Roxboro and western Pierrefonds.

My basement windows were hit by spring flooding. What should I do?
If the sealed unit is foggy, we replace it with a custom unit. Since the thermos goes into the existing frame, the frame has to be sound; if water damaged it, we'll tell you during the free assessment, before any quote.
Why are only my basement windows in Pierrefonds foggy?
They sit closer to the ground, stay cooler and are often in a damp room, which puts more strain on the seal. When it fails, fog settles between the panes. A replacement unit with argon and Low-E reduces condensation on the inside.
