Thermos replacement in Rosemont–La Petite-Patrie

This borough is defined by its plexes: rows of brick duplexes and triplexes with front balconies, outdoor staircases and back lanes. Much of it dates from the first half of the 20th century, and most original windows have long since been swapped for thermos units. Further east, toward Nouveau-Rosemont, postwar bungalows and apartment buildings bring more standardized window sizes into the mix.

In a plex flat, the kitchen and bathroom put out plenty of moisture in a small space; once a thermos seal fails, the fog settles between the panes and stays there. We build a replacement unit to the exact size of your existing sash, which is often non-standard in these buildings. Double glazing with argon and Low-E handles most cases, while triple-pane can make sense on a cold, northwest-facing wall.

For an upstairs flat, the unit often goes up the spiral outdoor staircase or comes in through the lane — tell us ahead of time which route works best. Street parking is frequently reserved for permit holders, so a free spot near the door during installation really helps. Renting? Replacement is usually the landlord's responsibility, and we can email the quote straight to them.
