Window Crank Operator Repair

Fix Your Window Crank—Save Hundreds

When your casement or awning window crank stops working, most window companies will try to sell you a brand new window. But in most cases, a simple $75-250 repair can restore full function—saving you $500+ compared to replacement.

At Centennial Glass, we maintain Ottawa's largest inventory of window crank operators, handles, and related parts. We stock components for virtually every window brand, including discontinued models from the 1980s and 1990s.

DIY or Professional Repair?

Some handy homeowners can replace a crank handle or simple operator themselves. However, professional repair is recommended when:

• You're unsure which replacement part you need
• The operator is hard to access or remove
• The window frame or hinges may also need attention
• You want the repair warrantied

Visit our showroom: Bring in your old crank handle or operator and our parts experts can match it to a replacement. We have thousands of parts in stock for immediate pickup.
