Services
Windows
We supply energy-efficient vinyl windows including casement, single/double hung, sliding, awning, and custom-shaped options. Our products combine durability with aesthetic appeal, offering features like tilt-in sashes for easy cleaning and multiple color choices. Partnering with brands like North Star and KV Custom, we provide solutions that enhance home insulation and natural light while requiring minimal maintenance.
Doors
Our door selection includes steel and fiberglass entrance doors, patio doors, and storm doors designed for Canadian climates. KV Custom products feature thermal insulation, UV-resistant finishes, and security-focused designs. We offer white or custom-colored options with woodgrain textures that resist cracking and warping, ensuring long-lasting performance and enhanced curb appeal for residential properties.
Vinyl Siding
We provide durable vinyl siding with UV-resistant coatings and over 35 color options to suit various architectural styles. Our products include horizontal and vertical board-and-batten styles, soffits, and shakes that resist moisture damage. Brands like Kaycan and Novik offer low-maintenance solutions that enhance home aesthetics while providing lightweight, impact-resistant protection against harsh weather conditions.
Seamless Eavestrough
Our seamless aluminum eavestroughs come in 13 Kaycan colors with matching accessories like downpipes and leaf guards. The system prevents water damage to foundations and landscaping while requiring minimal maintenance. We recommend Proguard II gutter guards to prevent clogging and extend system lifespan, offering both functional protection and visual consistency for residential properties.
Vista Railings
The Vista aluminum railing system features powder-coated finishes in five standard colors with regular, wide, or framed glass picket options. Its non-welded design allows custom fitting during installation while resisting rust and corrosion. The low-maintenance system includes continuous top rails for easy assembly, combining safety with modern aesthetics for residential decks and outdoor spaces.
