We Provide Windows Replacement Service

Professional Window Installers are Serving Toronto and GTA

Replacing windows is a big decision, but it’s an important one. With the rising costs of energy, your current windows may be costing you more money to keep them than replace them.

WELDA Windows and Doors is proud to offer replacement vinyl windows with Energy Star energy efficiency ratings that will fit your budget and save you money as you heat and cool your Toronto home. There are a wide variety of attractive styles to choose from: double hung windows, slider windows, casement windows, bow windows, bay windows, awning windows and more. You can choose from many types, styles, colours, and options. The only criteria – it has to be a window we’d feel comfortable putting in our own home… or we won’t install it.
