Red Deer's Window & Door Specialists! Window Masters was established in Red Deer in 1993, and has been Red Deer's leader in window and door replacement ever since. In January of 2013, the assets of Window Masters were purchased by Wolf Creek Building Supplies in Lacombe. This has given us more buying power than ever before! We are committed to giving Central Alberta the best price possible on new windows and doors. We offer products from two-time Energy Star manufacturer of the Year, All Weather Windows, as well as products from Kohltech Windows & Entrance Systems. We are also a Pella-certified contractor!
