Thermos replacement in Dollard-des-Ormeaux

Much of Dollard-des-Ormeaux was built from the 1960s onward, on streets of split-levels, cottages and bungalows with good-sized lots. These homes tend to mix several window formats: a big bay or picture window in the living room, narrower units on the half-levels and small basement windows. Most also have a patio door leading to the backyard or the pool, which gets opened and closed constantly from spring to fall.

When a house still has its original windows or a first round of replacements, the thermos units often fail one after another over a few years. Instead of buying new windows, we replace the failed sealed units and upgrade the glass while we're at it: double or triple glazing, argon gas and Low-E to hold heat better. The backyard patio door gets a tempered-glass unit, which suits a door that sees that much traffic.

Driveways and quiet residential streets make access easy, so we park right in front of your house. If your patio door opens onto an in-ground pool or a raised deck, clear the area in front of the panel before the visit. A tip: walk around the house on a cold, sunny day, when fog between the panes is easiest to spot, and note every affected window before you call.
