The crank operator is a small gearbox that does heavy work: every casement and awning window opens and closes through it, often against wind load. When the gears strip, the handle spins uselessly; when they seize, the window is stuck open or shut. We replace worn operators with the correct match for your window, and most crank repairs are finished in under an hour.
Operators come in more varieties than you would expect: single-arm, dual-arm, dyad, and split-arm styles, in left and right hands. Fitting the wrong one leaves a window that binds or never quite closes. We identify the exact style and hand, and we carry the common ones with us.
A stiff crank is sometimes a warning rather than the fault itself. If the sash has sagged on worn hinges it drags on the frame, and the operator strains until it strips. That is why we check the hinges with every crank call, and handle window hinge repair on the spot when needed rather than leaving a new operator to wear out the same way.
Crank repairs are a same-day favourite in the North Bay core. For the full picture on side-swinging windows, see our casement window repair service, or book a full window service if several windows are due.
