Cranks, locks, balances

Window hardware and seal repairs

When a window stops opening, closing or locking properly, the glass and frame are often fine. What wore out is usually small: a crank operator, a lock, a balance or weatherstripping, and many 1990s and 2000s Brampton homes are at that age. We connect you with an independent local pro who finds the right part and fits it. For other problems, see all window services.

Symptom to part

Match the symptom to the part

These are the usual culprits behind each symptom.

Crank spins but the window doesn't move

Stripped gears in the operator, or a handle worn smooth. A new operator or handle fixes it.

Won't close tight

A bent operator arm, a worn hinge or a sagging sash. Drafts and whistling on windy days are the clue.

Lock won't catch

The lock and keeper have drifted apart, or the lock is worn. An adjustment or a new lock.

Sash drops or won't stay up

Balances hidden in the side tracks of a hung window hold the sash up. When one fails, the sash slides down.

Screen keeps jumping the track

Usually a bent frame or missing clips: a screen repair for the same visit.

Crank windows

Casement operators and hinges

A casement's crank turns a small gearbox, the operator, which pushes an arm that swings the sash. Forcing a frozen or stuck window is the usual way the gears strip. Hinges along the top and bottom carry the sash, and when they wear, it sags and catches the frame.

Sliders and hung windows

Slider and single-hung balances, rollers and latches

Sliding and hung windows have their own moving parts, each replaceable on its own.

Balances

Springs in the side jambs hold a hung sash at any height. A pro matches the type and swaps them.

Rollers

Worn wheels under a sliding sash make it drag or stick open. New rollers fix it.

Latches and locks

A slider that won't lock often has a latch that no longer meets its keeper. An adjustment or new latch lines them up.

Before and after

A snapped crank handle, replaced on its own

One broken handle doesn't mean a new window.

Drafts and leaks

Weatherstripping and exterior caulking after freeze-thaw winters

Winters here cross freezing on many days, and every swing works at the seals around a window.

Inside, weatherstripping flattens, tears or shrinks. New strips are cut to fit, and on casements the job pairs well with a new operator.

Outside, caulking where the frame meets the brick cracks and pulls away. A pro runs a new bead and checks that a slider's drain holes are clear.

What affects the quote

What goes into a repair quote

Repairs are priced by the part and the time. These change it:

  • Which part, and whether it's still made or needs a close match
  • How many windows need the same fix
  • Window type: casement, awning, slider or hung
  • Access: upper floors, stairwells, basements

A photo of the part and any frame label helps the pro source it first.

Children at home

Child safety and window locks

Opening-control devices limit how far a sash opens, and many release with a quick press by an adult. A pro can fit them and check that existing locks hold.

A bedroom window may also be a way out in an emergency, so avoid devices that need a key.

Basement windows

Stiff or painted-shut basement windows

In a basement bedroom or unit, an unused window can seize with paint or grit. A pro can free it and check that it opens fully and stays open, which matters most where someone sleeps.

If it's too small to be a way out, see basement windows.

Beyond parts

When hardware is no longer the fix

A new part won't help if the frame is failing, with cracked corners, a sash that won't sit square or a rotting sill, or if the parts are no longer made.

The pro should say so plainly. Fog between the panes can still be fixed on its own, and when frames are going, price replacement windows too.
