A skilled DIYer with the right tools can install a replacement window, but just because you can, doesn’t mean you should. The process of replacing windows can be complicated, especially when unexpected issues arise, like when the window opening is no longer square. Professional window contractors are experienced and proficient with measuring for replacement windows, removing old windows and installing new replacement windows.

They have come across a variety of issues and know how to overcome them for the perfect window install. Window manufacturers do not provide a labour warranty, this is covered by the contractor. If the window is installed improperly, this can lead to a host of issues and may even void the manufacturer’s warranty as the window was not installed by a professional contractor.
