Our Repair Process

We carefully examine every part of the casement window crank to find the root cause of the problem. Then, we replace any broken or worn parts with exact fits. Finally, we make sure everything moves smoothly by applying lubrication and fine-tuning the mechanism.

Inspection and Diagnosis

We start by looking closely at the entire crank mechanism. This includes the handle, gears, and arm connected to the window sash. We check for signs of wear, rust, or damage. Sometimes, the crank may be loose or misaligned, which can cause it to stick or fail.


We also test the crank action to see if it opens and closes the window properly. If the crank is stiff or slipping, we note exactly where the problem lies. This process helps us decide which parts need attention or replacement.

Component Replacement

After diagnosis, we remove the damaged or worn parts carefully. Our team carries a selection of high-quality replacement gears, handles, and arms to match most window types. We replace only what’s necessary to keep costs reasonable.


Each new component is installed to fit perfectly, avoiding any future issues. We make sure the crank mechanism is secure and free of play. If needed, we also repair or tighten the mounting screws to hold the crank firmly in place.

Lubrication and Adjustment

Once the parts are replaced, we apply a special lubricant to all moving joints. This reduces friction and prevents rust from forming again. Proper lubrication helps the crank operate smoothly and last longer.


We then adjust the crank arm and gears so the window moves easily without binding or sliding. We test the window several times to confirm everything works as it should. Small adjustments ensure consistent performance and ease of use.
