Our Repair Services

We ensure your casement window crank works smoothly by carefully checking every part, fixing any misalignment, and swapping out broken components as needed. Our approach focuses on accuracy and proper function to extend the life of your windows.

Diagnosis and Inspection

We begin by thoroughly inspecting your casement window crank. This includes checking the handle, gears, and linkage for wear, damage, or dirt buildup.


We look for signs of rust, stripped gears, or loose screws that can cause the crank to stick or fail. Our team tests the crank’s movement to spot any resistance or uneven motion.


This detailed inspection helps us identify the exact problem quickly. We also assess surrounding window parts to rule out external causes of crank issues.

Realignment and Adjustment

When parts are out of place, the crank won’t open or close the window properly. We carefully realign gears and arms to restore smooth operation.


We adjust tension and tighten screws to ensure all components move in sync. Our goal is to eliminate gaps and reduce friction that can damage the mechanism over time.


We also check and adjust the window sash to avoid unnecessary strain on the crank system.

Crank Replacement Solutions

If parts are broken or too worn, replacement is the best option. We offer high-quality, compatible replacement cranks designed for long-term durability.


Our team removes the old crank without damaging the window frame. We then install and test the new crank to make sure it fits perfectly and works smoothly.


We can replace just the crank handle or the entire mechanism, depending on the damage. This gives you a reliable, easy-to-use window again.

Our Tailored Residential and Commercial Solutions


We focus on fixing casement window cranks with careful planning, choosing the right parts, and improving energy use. Our approach adjusts to the needs of homes and businesses, making sure repairs last and work well.



Custom Repair Planning


We start by inspecting each window crank mechanism carefully. This helps us understand how much wear or damage exists. For homes, we often find simple fixes like replacing the crank or tightening parts.


For commercial properties, we check for heavy use and may suggest stronger materials or special parts. We make a clear plan that fits the window’s condition and the client’s budget. This ensures no unnecessary work is done.


Our goal is to fix the window crank so it opens and closes smoothly. We also aim to prevent future problems by addressing the root causes, like rust or misalignment.


Material and Brand Compatibility


We use parts that match the window’s original materials and brand. This keeps the repair durable and maintains the window’s function. Using standard or mismatched parts can cause failure or damage.


Our team has access to many brand-name parts for casement cranks, including hardware from popular window manufacturers. We check compatibility before ordering any piece.


If a brand-specific part isn’t available, we look for close matches tested for quality. We explain choices clearly, so clients know what we use and why. This reduces risks and ensures a precise fit.


Energy Efficiency Improvements


Fixing the crank mechanism can improve a window’s seal and energy use. We test the repaired window for air leaks and tightness. A smooth crank means the window closes fully, stopping drafts.


For older windows, we might add weather stripping or replace worn gaskets. These small changes help keep heating and cooling costs down.


We also check if the crank repair can support energy-saving glass or screens without extra stress. Energy efficiency helps both homes and businesses save money over time.
