Your thermos specialist in Town of Mount Royal
Fog between the panes means the seal on your sealed unit has failed. In Town of Mount Royal, the large windows of upscale 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 character.
Custom glass for non-standard dimensions, free diagnosis, transparent pricing from $150.

Local context
Town of Mount Royal (TMR): sealed units in a planned garden city
Designed in the early 20th century as a garden city, the Town of Mount Royal (TMR) is laid out around its train station, with boulevards radiating out from the centre. Tree-lined streets are home to single-family houses in a range of styles, from English-inspired cottages to plainer postwar homes. Casement windows, large living-room picture windows, French doors onto the garden and, in some houses, divided-lite windows give the facades their character.
Under a dense tree canopy, some front facades stay shaded and damp while the back of the house gets full sun from the garden. Those uneven conditions mean the sealed units in a single house age at different rates. We replace only the foggy units, with Low-E and argon for sunny rooms and tempered glass for French doors and large picture windows. The frame and woodwork stay in place.
TMR is known for its strict planning rules. Replacing a sealed unit in the existing frame doesn't change the frame or the opening size, but check with the Town before any broader exterior project. Street parking is regulated, so keep a spot free in the driveway on installation day. For a large picture window, move furniture and curtains back about two metres.
