Finishing the exterior of your house with high-quality vinyl siding offers great curb appeal while offering easy maintenance and great protection. A great barrier against bad weather, insects and rot, our selection of Kaycan products provides a long-lasting professional finish.

We also carry metal siding from trusted suppliers like Ideal Roofing and Vicwest. The right metal cladding will provide years of low-maintenance protection against bad weather, rot and even fire. This lightweight material is easy to install, looks good and is long-lasting.
