How To Clean Your Double Hung Windows And Avoid Alignment Mistakes
As shown in the video above, cleaning your vinyl double-hung windows is a simple process. But occasionally, you might run into a minor issue—like a sash coming loose from the balance system. Don’t worry! Your local Window Depot has you covered with this step-by-step guide.
Cleaning Your Window
- Start by unlocking the window. Check the lock indicators on either side to confirm it’s fully disengaged.
- Using the lift rail, raise the bottom sash.
- Press the tilt latches located beside the locks and gently tilt the sash inward toward you.
- Keep the sash level as you wipe down the glass with paper towels or a microfiber cloth and your favorite glass cleaner.
What to Do If the Sash Comes Loose
Sometimes, during cleaning, the sash may disconnect from the balance system on one or both sides. If that happens, here’s how to realign it:
- Carefully tilt and remove the sash from the window frame. Set it aside somewhere safe.
- Locate the window balance channel on each side.
- Insert a flathead screwdriver into the balance and hold it in place. Slowly turn the screwdriver to adjust the spring-loaded balance—be cautious, as it can snap upward if released suddenly.
- Align both balances so they’re even on each side.
- Reinstall the sash by inserting the pivot pins into each balance shoe. Apply slight downward pressure on the sash and tilt it back into place.
- Close the window completely and re-engage the locks.
That’s it—your window should now operate smoothly and stay properly aligned!
