How to Fix Stuck Jalousie Windows: A Guide for Commercial Buildings

Commercial jalousie windows, with their multiple glass slats that open and close in unison, are popular for their excellent ventilation and modern aesthetic. However, these windows can sometimes get stuck, affecting their functionality. If your jalousie windows are stuck, here’s a comprehensive guide to get them working smoothly again.

STEP 1:  Identify the Problem

Before fixing a stuck commercial jalousie window, identify the cause. Common issues include:

Corrosion or rust: 

Metal parts can corrode over time, especially in environments with high humidity.

Dirt and debris: 

Accumulated dirt can hinder the movement of the slats.

Broken or worn-out parts: 

Components like the operator (the mechanism that opens and closes the slats) or the clips holding the slats can break or wear out.

STEP 2: Gather Your Tools

You will need the following tools and materials to fix your stuck commercial jalousie windows:

• Screwdriver (Phillips or flathead, depending on your window’s screws)

• Pliers

• Lubricant

• Soft cloth or rag

• Replacement parts (if necessary)

• Cleaning solution

STEP 3: Clean the Window

Start by cleaning the window thoroughly:

1. Remove dirt and debris: Use a brush or a vacuum to remove loose dirt and debris from the window tracks and around the slats.

2. Wipe the slats: Use a soft cloth and a mild cleaning solution to clean the glass slats. Ensure they are thoroughly dry to prevent moisture from causing rust.

STEP 4: Lubricate Moving Parts

Proper lubrication can often solve the problem of a stuck jalousie window:

1. Apply lubricant: Spray the lubricant onto the moving parts of the window, including the operator mechanism, the tracks, and the hinges.

2. Operate the window: Open and close the window several times to distribute the lubricant evenly and ensure smooth operation.

STEP 5: Check for Rust or Corrosion

If you notice rust or corrosion on any metal parts:

1. Remove rust: Use a wire brush or sandpaper to remove as much rust as possible from the affected parts.

2. Apply rust inhibitor: To prevent further rusting, apply a rust inhibitor or a rust-resistant primer to the cleaned areas.

STEP 6: Inspect and Replace Broken Parts

Examine the window for any broken or worn-out parts:

1. Check the operator: If the operator mechanism is damaged or not working correctly, it may need to be replaced. Unscrew the operator from the window frame and install a new one.

2. Inspect the clips: The clips that hold the slats in place can become brittle and break over time. If you find any broken clips, replace them with new ones.

STEP 7: Adjust the Window

Sometimes, adjusting the alignment of the slats can solve the problem:

1. Loosen the screws: Slightly loosen the screws that hold the slats in place.

2. Realign the slats: Adjust the slats so they are properly aligned and move smoothly.

3. Tighten the screws: Once the slats are aligned, tighten the screws to secure them in place.

STEP 8: Test the Window

After completing the above steps, test the window to ensure it operates smoothly:

1. Open and close the window: Check if the slats open and close easily without sticking.

2. Make further adjustments: If the window is still sticking, repeat the lubrication and adjustment steps until it moves smoothly.

Preventive Maintenance

To keep your commercial jalousie windows functioning well:

• Regular cleaning: 

Clean the windows and tracks regularly to prevent dirt buildup.

• Routine lubrication: 

Lubricate the moving parts periodically to ensure smooth operation.

• Inspect for damage: 

Schedule regular inspections to check for signs of rust, corrosion, or wear and address issues promptly.
