Thermos replacement in Plateau-Mont-Royal

On the Plateau, many duplexes and triplexes have been converted into condos, so one building often has several owners, each responsible for their own windows under the declaration of co-ownership. Upstairs, you'll find casement or sash windows on the front, glass balcony doors and, at the back, windows overlooking the lane. In Mile End, converted former industrial buildings add rows of large windows.

South-facing facades, whether on the street or lane side depending on the block, get intense summer sun that wears on the sealant, while north-facing rooms stay cold and build up humidity. The result: one unit can have a sound thermos next to one that's completely fogged. We replace them case by case, with Low-E and argon on the sunny side and tempered glass for balcony doors.

Spiral outdoor staircases can't always handle a large unit, so the lane, a back door or the inside stairwell are often better options. With sector-based parking permits, try to keep a spot free in the lane or in front of the building. In a condo plex, coordinate the date with your neighbours if several units are affected, so one visit covers the whole assessment.
