Our mission is to transform homes by offering a premium solution, sure to reflect the homeowner’s individuality and style



Integrity, transparency, and culture. All traditional core values which have been important to our business and many businesses like ours, throughout the years. While these values are essential—we wouldn’t have survived 45 years in business without them—it is our guiding values that hold us to a higher standard.


As we continue to lead our industry, we will always take pride in our approach of producing superior products, that go above and beyond the standard.


We believe that once you invest in our premium vinyl siding, you should not have to worry about it for many years to come. We take all lengths to provide you with worry-free solutions, including customer-driven support, 25 year no-fade warranty on Plus Colors and our limited lifetime warranty on all our vinyl siding products as well as offering an exceptional windows and patio door warranty.


We take great pride in our dedication to continue to grow our company as Canada’s largest privately owned vinyl siding manufacturer. Our KP family of employees and community partners will continue to benefit from our growth and sustainability.


At the end of the day, your home is a reflection of who you are. We know the importance of offering many styles and colours to suit people’s individuality and tastes. Our products have the ability to transform a house into a home.


As architectural styles change (as they tend to do), we continually change along with them. By adding different colors, textures, and sizes to our lineup of products, we will ensure that you can always find a product to work in your design, no matter how modern it may be.


KP Building Products Ltd. is a privately owned, family run company that has grown through hard work and dedication towards producing premium quality products and customer service. We believe that our internal team and external partnerships are all part of the KP family, and that mindset will continue to drive everyone’s success!
