How to Fix a Double-Hung Window That Won’t Shut Properly

When a double-hung window refuses to close, it allows drafts, noise, or other disturbances into the home, and can even increase energy consumption and security problems. If you have a troublesome double-hung window, here we’ll guide you through several real-world steps to resolve the issue once and for all.

Understand the Basic Construction of a Double-Hung Window

Before initiating the repair, understand the installation of a double-hung window. A double-hung window has two operating sashes (an upper sash and a lower sash), which travel vertically up and down within their tracks. Most modern models feature either spring-loaded balances or block-and-tackle systems to assist in raising the sash and maintaining its position.

There are generally three causes for such windows not closing on their own:

• Distorted frames
• Sliding or misaligned tracks
• Bent or damaged hardware
• Paint deposits
• Filthy or blocked channels

How to Repair and Troubleshoot the Window: Guidance

1. Inspect for Obvious Obstructions

Begin opening and closing the window slowly. One may find debris of something lodged in the track. To inspect every corner and hidden space make use of the light.

Fix: Clean the window tracks to remove any dust or dirt. Then, wipe them using a damp cloth. If the window still sticks, apply a small amount of silicone spray to make it slide easily.

2. Is Checking Sash Alignment

Sometimes the sash (the moving part) can shift. When the window appears crooked or does not fit into the frame correctly, it may require realignment.

Fix: Remove the sash gently, following the directions provided by your window maker, then reinsert it, ensuring it is fully parallel with the side tracks or balance parts. If the balance shoe is in either the incorrect high or low position, use a flathead screwdriver to return it to its correct position.

3. Check the Window Balances

Window balances are the concealed springs or coil mechanisms that facilitate easy opening and closing of the sash. If the parts break or slip loose, the weight of the window sash may feel heavy, or it may be challenging to move, which can cause the window to close improperly.

Fix: Tilt the window gently inside, and look for the balance mechanisms on both ends. If the balance system is broken or removed, you may need to replace the entire system. Contact your window manufacturer or Best Offer Glass for compatible replacement parts.

4. Look for Frame Warping

Wooden window frames are vulnerable to moisture, swelling, or possibly warping. Warped frames cannot be aligned, meaning that sashes do not close evenly.

Fix: Gently sand congested areas where the sash obstructs. In cases where the wood is badly distorted, have a professional assess for potential replacement. Use moisture-resistant materials for lasting effects.

5. Check Locking Mechanism and Hardware

Most of the time, the actual problem is caused by the lock, not the window. If a lock is bent or slightly misaligned, the window will never close completely.

Fix: Make the screws loose so that the lock can be moved and lined up with the latch. Replacement parts can be procured from most hardware stores in case of damage, or we can be consulted for proper fitting.

6. Paint Build Up Repair

Paint is a common culprit in old wood windows. Paint can make the window shut if there are excess coats on the edges or if grease and dirt have built up there.

Fix: Use a utility knife to cut along the painted line where the sash and frame meet. Lightly tap with a rubber mallet to loosen the frame. Sand the edges away for paint buildup.

7. Test the Weatherstripping

Old, dried-out, or misaligned weatherstripping can cause resistance when closing a window. It may also prevent the sash from sealing correctly.

Fix: Worn-out weatherstripping shall be replaced with an adhesive-backed type suitable for the specific weather conditions. Press to firmly set an airtight seal.

Preventive Supervision for Avoiding Future Issues

Though the window has been repaired, you may sense that some preventive steps can be taken so as not to have to repeat these concerns:

• Clean window tracks every month.
• Lubricate moving parts every six months.
• Apply paint in thin coats to prevent buildup.
• Monitor for moisture damage seasonally.
• Open and close your windows frequently to prevent them from sticking.
• They should be opened and closed frequently to prevent the windows from sticking.
