Vinyl Window Installation in Markham

WindowFixers.ca supplies and installs custom vinyl windows across Markham, from the heritage houses along historic Main Street Unionville to the newer family subdivisions of Cornell, Berczy Village, and Cathedraltown. As one of the GTA's largest and fastest-growing cities, Markham blends century homes with two decades of new builds — and both eventually need their windows replaced.

We measure every opening, custom-order your windows to an exact fit, and install them with our own crew — never a subcontractor. Markham homeowners get honest direct pricing, ENERGY STAR® rated Low-E glass as standard, and a tidy one-to-three-day install with full removal and cleanup.
