Thermos replacement

Thermos replacement: new glass without a new window

When only the glass in a window is fogged or broken, there's no need to replace the whole window. We replace the thermos (the sealed glass unit) and keep the frame in place, across Greater Montreal.

Why replace just the thermos

The frame stays

If the window frame is in good shape, only the glass unit is changed.

A clear view again

A new sealed unit gets rid of the fog trapped between the panes.

Less work

Nothing to take apart around the window: walls and trim stay untouched.

Cracked or broken glass

A cracked or broken pane is replaced the same way.

When does a thermos need replacing?

  • Fog or condensation appears between the two panes and can't be wiped off.
  • Whitish streaks or spots stay inside the glass.
  • The glass is cracked or broken.
  • The glass feels colder to the touch than it used to in winter.
What if the frame is damaged? If the frame is rotten, warped or drafty, new glass won't be enough: replacing the whole window is the better option then.
