How to Easily Repair Double-Hung Windows Yourself

Double-hung windows are a popular choice for many homeowners due to their classic design and functional benefits. However, like any other window type, they can experience issues over time. One common problem is a double-hung window that won’t stay up or keeps falling shut. While replacing a double-hung window altogether will start at around $200, in many cases, repairing a double-hung window is an easy project you can do yourself with just a flathead screwdriver and a few minutes of your time.

Diagnosing the Issue

Before attempting to repair your double-hung window, it’s important to diagnose the problem. One of the most common causes of a double-hung window that won’t stay up is a disconnected or misplaced balance shoe. Each double-hung window has four balance cartridges, two per jamb liner. If one of the balance shoes inside isn’t working properly, the sash will slide down when you attempt to raise it.

To determine if the balance shoe is the issue, locate it in the casing of the window’s outer frame. In the case of dropped windows, the balance shoe is usually pushed to the bottom of the frame. If the balance shoe is disconnected or misplaced, it will need to be adjusted or replaced.

Adjusting a Disconnected Balance Shoe

If the balance shoe is simply disconnected, you can adjust it yourself with a flathead screwdriver. Follow these steps:

1. Locate the tilt pin at the bottom of the window sash. The tilt pin must fit inside the balance shoe for the window to function correctly.
2. Examine the balance shoe. If it has a “U” shape within it, this means it’s in the locked position. However, you want the shoe to be unlocked, so rotate it with a flathead screwdriver until it resembles a “C.”
3. Guide the shoe up the frame with a screwdriver until it’s within a few inches of the disconnected sash, then lock the shoe back into place.
4. Slide the sash back down and re-engage the tilt pin with the balance shoe.
5. For extra assurance, unlock the top of the sash and tilt it inward the way you would when cleaning a window. Knock on the area you just reconnected a few times, and then lock the sash back into its vertical position.

By following these steps, you should be able to reconnect the balance shoe and restore your double-hung window’s functionality.

Replacing Broken Parts

If the balance shoe is damaged or worn out, it may need to be replaced. This is a slightly more involved process, but it’s still a DIY-friendly repair. Here’s how to replace a balance shoe:

1. Remove the window sash by unscrewing the stops on the inside of the window frame near the lower sash and pulling the sash toward you.
2. Locate the balance shoe in the jamb liner and remove it.
3. Insert a new balance shoe into the jamb liner, making sure it’s properly aligned and locked into place.
4. Reinstall the window sash by positioning one cam, then the other, onto the top of each locking terminal.
5. Level the tipped sash, then raise the sash top and snap it back into the vinyl jamb liners.
6. Lower the installed sash, and the braking pawls on each side of the sash will be released.

If the locking terminal is broken, you may also need to replace it. This involves detaching the top of the tensioning spring from the holding pin, restringing the pulley system, and installing a new locking terminal.

It’s important to note that the repair process may vary depending on the type of double-hung window you have (wood or vinyl) and the specific manufacturer. Always refer to the window’s product literature or contact the manufacturer for specific instructions.

When to Call a Professional

While many double-hung window repairs can be done by a homeowner with some basic tools and a little know-how, there are some instances when it’s best to call in a professional:

• If you’re not comfortable working with the window’s components or don’t have the necessary tools
• If the window is severely damaged or has multiple issues
• If the window is made of specialized materials or has a unique design
• If you’re unsure of the cause of the problem or how to properly diagnose it

A professional window repair service will be able to assess the issue, provide an estimate for the repairs, and complete the work quickly and efficiently. They may also offer a warranty on their work, giving you peace of mind.

In conclusion, repairing a double-hung window that won’t stay up is a task that many homeowners can tackle themselves with a little guidance and the right tools. By diagnosing the issue, adjusting or replacing the balance shoe, and following best practices for reinstalling the window sash, you can restore your double-hung window’s functionality and save money on costly replacements. However, if you’re unsure or the damage is extensive, don’t hesitate to call in a professional for assistance.
