However, like any moving part of your home, they can develop issues over time. At Columbus Exterior, we fix and replace windows. We know that many common casement window issues can be solved with simple tools and some basic skills.
In this guide, we’ll share the best tips for repairing casement windows. These will help you keep your windows in good shape without spending much on replacements.
1. Fixing a Jammed Crank Handle
One of the most common issues with casement windows is a crank handle that refuses to open or close the window. This is often caused by worn-out gears in the window operator or debris clogging the mechanism.
Repair Tip:
-
Remove the crank handle cover using a screwdriver.
-
Inspect for visible damage to the gears.
-
Clean out any dirt or debris inside the crank box.
-
Lubricate with a silicone-based spray (avoid WD-40 as it attracts more dust).
-
If the crank is stripped or broken, replace it with a matching part from your hardware store.
Columbus Exterior recommends checking crank handles every season to avoid long-term damage.
2. Realigning the Window When It Won’t Close Properly
Casement windows may stop closing tightly if they fall out of alignment. This can be due to loose hinge screws or warping over time.
Repair Tip:
-
Open the window fully to access the hinges.
-
Slightly loosen the screws on the top and bottom hinges.
-
Gently push or pull the sash to align it with the frame.
-
Retighten the screws and test for smooth closure.
A well-aligned window stops drafts and boosts security. These are two key priorities for us at Columbus Exterior.
3. Cleaning and Lubricating the Hinges and Tracks
Over time, dirt and grime can build up in the hinges and tracks, making it difficult to open or close the window.
Repair Tip:
-
Use a vacuum or a brush to remove loose debris from the window tracks.
-
Wipe down the area with warm, soapy water.
-
Dry completely with a cloth.
-
Apply a silicone-based lubricant to the moving parts.
Regular maintenance is key to extending the life of your windows. Columbus Exterior always advises homeowners to clean their window hardware twice a year.
4. Tightening Loose Screws and Hardware
With time, window components like the hinges, locks, and crank operators can loosen, especially with frequent use.
Repair Tip:
-
Check all visible screws around the sash, crank, and hinges.
-
Tighten any loose screws with a screwdriver.
-
If screws are stripped or don’t tighten, consider replacing them with slightly longer ones.
This small step can greatly boost your window’s performance. It’s a regular part of our repair services at Columbus Exterior.
5. Replacing a Faulty Crank Operator
If the window crank no longer moves the sash, it’s likely the internal mechanism has failed.
Repair Tip:
-
Fully open the window and unscrew the operator from the sash and window sill.
-
Remove the cover to expose the linkage arm.
-
Replace the old operator with a new one of the same type.
-
Reattach the crank and test for proper operation.
This repair is easy but important for making your casement windows work properly again.
6. Weatherproofing and Sealing Air Leaks
Over time, casement windows can develop small gaps that let in air or water. These issues often result from worn-out seals or cracked caulk around the frame.
Repair Tip:
-
Inspect the weather stripping around the window.
-
Remove any old or damaged seal.
-
Apply new weather stripping designed for Casement Window Repair.
-
Use exterior-grade caulk to seal any visible cracks around the frame.
At Columbus Exterior, we stress sealing your windows before winter. This helps save on energy bills and boosts comfort.
7. Fixing a Misaligned Lock
A window lock that doesn’t latch securely could be caused by a misaligned strike plate or a warped sash.
Repair Tip:
-
Check if the lock aligns properly when closed.
-
If not, loosen the screws on the strike plate and adjust its position.
-
Retighten the screws and test the lock.
Window security is essential, and this simple adjustment can restore peace of mind.
