Window repair service in Montreal

Planning to replace your windows and doors? Why spend a lot of money when you can simply repair them?

Have your windows repaired vs. replaced

The Basco Montreal window repair team has the expertise to evaluate the problems with your windows and propose alternative solutions to the complete replacement of your windows.

Did you know that any type of window can be re-glazed, meaning that the sealed unit of glass can be replaced? Whether the broken window has double or triple glazed sealed units, has a wood, metal or vinyl frame, we can replace it! We can even match the grilles you have so that the new window unit will perfectly match the ones next to it.

There are several specific instances where we can perform a double pane window repair and save you the higher cost of a complete window replacement:

  • If the glass in your double-pane window is cracked, we can replace the thermos (the sealed unit or the glass portion of the window).
  • If the sealed unit fails and becomes fogged, or if there are deposits between the panes, we can defog the window at a fraction of the replacement cost, or replace the thermos unit if necessary.
  • If you simply want to replace your window with a more efficient Low E argon window, we can save you money by replacing the thermos unit instead of the entire window.

Why choose Basco Montreal

Basco Montreal has partnered with local suppliers not only for glass replacement, but also for window hardware repair, weatherstripping repair and window caulking. This allows us to quickly repair a broken window operator, replace hanging window sash balances or repair any type of broken window mechanism.

If your window is leaking, there is no need to replace it. It's a good idea to evaluate the exterior caulking for signs of shrinkage, cracks and gaps, and proactively address the issues to extend the life of your windows. This will minimize air and water leakage and prevent further structural damage to your windows. Our team has the expertise and is equipped to professionally replace the caulking around your windows.

We dealt with Basco to restore our wood windows. We got the best value on the market. A team that is more than efficient, friendly, and unparalleled in skill. One of our best experiences if not the best experience with a contractor!

A very professional and well organized team. They changed 6 of our windows (Low-E Argon) and there has been no fogging since. The windows are perfectly clear no matter the season. I highly recommend this company

First, we received a clear and understandable estimate. The work was done very well and with a smile. In addition, the technician graciously repaired one of our long-staggered door locks. A kind of extra that you don't often get... We are very satisfied
