Montreal Windows Need Winter Prep

Montreal’s long heating season, deep freezes, and older housing stock make windows a common weak spot, affecting comfort and monthly energy costs year after year.
Key warning signs include drafts near frames, frost inside glass, trapped pane moisture, sticking sashes, damaged wood, colder rooms, and street noise.
One or two minor problems may be repairable, but several issues at once, or windows older than 20 to 25 yr, usually favor replacement.
Frame choice matters: vinyl stays affordable and low-maintenance, fibreglass handles big temperature swings, and wood or wood-clad frames suit heritage-minded facades well.
Plan replacements before winter when possible, prioritize strong installation and sealing, and check current Quebec incentives and any required energy evaluation before signing.
