Your latch clicks shut, but your curtains still sway when the wind picks up. That subtle flutter along the windowsill is not coming through the glass. It happens because aging locks pull loose from their keeps, leaving tiny air channels along the bottom track. Cold air spills across your floorboards, chilling the room from the feet up while your heating system runs nonstop. Masking tape or rolled-up towels might muffle the draft for an evening. They do not fix a sash that has pulled away from its frame. We build replacements with Canadian materials meant to hold up against freezing regional winds. Every unit is fitted by our own full-time staff installers, so the hardware locks tight and stays airtight. Tag a friend who always keeps a space heater running under their desk. #OttawaHomes #Kanata #Barrhaven #WindowInstallation #OttawaRenovations #HomeComfort #Stittsville
