Your Local Vinyl Window Specialist in Thornhill
WindowFixers.ca serves all of Thornhill on both the Markham and Vaughan sides, from the mature, tree-lined streets of the old village to the established homes around Bayview, Yonge, and Royal Orchard. Thornhill is one of the region's older suburbs, so a great many homes still have their original or first-replacement windows.
We measure every opening, custom-order your windows to an exact fit, and install with our own crew. Thornhill homeowners get honest direct pricing, ENERGY STAR® rated Low-E glass as standard, and a tidy one-to-three-day installation with full removal and cleanup.
