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.
There’s more to replacing your existing entry door than just hanging a new door in an old jamb or settling for a pre-built, off the shelf door from a home center. With a new entry system from WELDA you get a complete entry door system with a variety of options allowing you to create a unique entrance to your home that combines the best low maintenance and energy efficiency features available.
WELDA porch enclosures are the greatest thing since sliced bread! But don’t take our word for it – ask anyone who’s had an enclosed patio installed. Porch enclosures are immensely practical additions to your home especially in the extreme Canadian climate.
Maximum visibility to complete privacy at the tip of a finger. The lever raises, lowers or tilts the blinds sealed between the insulated glass to ensure maintenance-free operation.
