ABOUT US

Your Leading Custom Door, Trim, and Hardware Supplier.

Riverside Door & Trim Inc. was established in May of 2005, but our roots go back much further. Our sister company (GSM Carpentry Ltd.) was established in 1983. It has very strong roots in the residential construction market in the tri-cities. We are a family owned and operated business with almost 50 years experience between the three owners. Riverside Door & Trim Inc. is an expansion of GSM with a showroom & manufacturing facility/warehouse to become the first "Supply & Install" Trim operation in the Waterloo Region.
