Window Repair: Cranks, Hinges, Balances & Locks

A window that won't open, close or lock usually doesn't need replacing. Window Whiz repairs cranks, hinges, balances, locks and latches, and seals drafts, on casement, awning, sliding, double-hung, hopper and tilt-and-turn windows. We carry common parts and track down hardware for older windows, including ones whose original parts are no longer made.

What we fix

  • Cranks (operators) that spin, grind or stick
  • Hinges and arms that sag or won't close tight
  • Balances on windows that won't stay open
  • Locks and latches that won't catch
  • Drafty windows that need resealing
  • Hardware for older and discontinued windows

Common problems and what fixes them

Most window problems come down to a worn part that can be replaced on its own:

  • The crank turns but the window doesn't move: the operator's gears are worn, so we replace the operator.
  • The window drags or won't close tight: the hinges or arms are bent or worn.
  • A hung window won't stay open: the balance has failed.
  • The lock won't catch: the lock or keeper is worn or out of line.
  • Cold air around the sash: the seals are worn, and we reseal the window.

Older windows and discontinued parts

Hardware wears out long before the rest of a window does. One customer had two 30-year-old windows with worn parts that were no longer made. Instead of replacing the windows, we worked out a way to get them working like new, which saved the customer a lot of money.

Photos help. Many operators and locks have a brand name or part number stamped on them, which makes finding the right part faster.

Repair first

We'll tell you when a repair is the better deal, even when that means less revenue for us. If a window is failing in several ways at once, we'll say so and quote a replacement as well.

What customers say

  • “I really didn't want the expense of 2 new windows but needed them to be functional and after 30 yrs., some parts had worn out. Brett from Window Whiz was able to fix them good as new! When the original parts were no longer available, Brett figured out a work around. I couldn't be happier with his work and in the end he saved me a lot of money.”

Common questions

Can you fix a window crank?

Yes. A crank that spins or grinds usually means a worn operator, which we replace. Stiffness can also come from bent arms or hinges, so we check those at the same time.

My windows are 30 years old. Can they still be repaired?

Often, yes. We carry common hardware and source specialty parts for older windows. When a part is no longer made, we look for a workable alternative before suggesting replacement.

Which types of windows do you repair?

Casement, awning, sliding, double-hung, hopper and tilt-and-turn windows, in homes and commercial buildings.

Can you come outside working hours?

We work a daytime schedule, but we book some weekend and evening appointments for people who can't take time off. Those spots are popular, so the wait can be longer.

Do you repair windows in condos and offices?

Yes. We fix inoperable windows for property managers and condo boards, with the documentation and invoicing they need.
