When Experience Matters

Everyone wants quality windows, but not everyone wants the same size or style. That’s why WELDA offers a full selection of styles that can accommodate any design need or architectural style. The only factor that won’t differ from style to style, or size to size is the quality. Our complete line of vinyl replacement windows is guaranteed not to flake, peel, blister, crack or corrode as a response to Ontario’s always-fluctuating environmental conditions. 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.
