Как снять и заменить створку одностворчатого окна (верхнюю и нижнюю)

Yes, you can often remove the bottom (operable) sash of a single-hung window for cleaning, repair, or replacement. Removing the top (fixed) sash is usually much more difficult, and often impossible without removing the entire window unit.

This guide provides step-by-step instructions for safely removing and reinstalling the bottom sash of most common single-hung windows, and explains the challenges with the top sash.

First, let’s clarify: what is a single-hung window? It’s a window where only the bottom sash slides vertically, while the top sash remains stationary.

Why Remove a Window Sash?

Common reasons to remove a sash include:

• Глубокая очистка: Allows easy access to all sides of the glass and frame. (See our window cleaning guide).
• Minor Repairs: Fixing broken cords, balances, or minor frame damage. (Explore common window repairs).
• Glass Replacement: Sometimes necessary if just the glass pane needs replacing (though often done by pros).
• Sash Replacement: If the sash itself is damaged beyond repair (rot, warping).

Safety First & Tools Needed

Always prioritize safety when working with windows.

Защитное снаряжение:

• Защитные очки (Essential!)
• Рабочие перчатки (Essential!)
• Dust mask (Recommended, especially with older windows)

Tools You’ll Likely Need:

• Flathead screwdriver (or putty knife)
• Pry bar (sometimes needed for older styles)
• Measuring tape (if ordering replacements)
• Helper (Recommended, sashes can be awkward)

Removing the Bottom (Operable) Sash

This is the part that slides up and down. Most modern vinyl or wood single-hung windows use one of these methods:

Method 1: Tilt-In Sashes (Most Common on Newer Windows)

1. Unlock & Raise: Unlock the window and raise the bottom sash about 3-6 inches from the sill.
2. Locate Tilt Latches: Find the small sliding latches or buttons located on the top edge of the sash frame (one on each side).
3. Защелки зацепления: Simultaneously slide both latches inwards (towards the center of the sash).
4. Tilt Sash Inward: While holding the latches, carefully pull the top of the sash towards you, tilting it into the room (usually to about 90 degrees).
5. Lift Out: Lift one side of the tilted sash upwards. This disengages the pivot bar (a small pin or bar at the bottom corner of the sash) from the balance shoe (the mechanism inside the side jamb track). Once one side is free, lift the other side out.

Method 2: Non-Tilt Sashes (Common on Older Wood or Aluminum Windows)

1. Поднять пояс: Lift the bottom sash partway up.
2. Locate Takeout Clips/Stops: Look inside the side jamb tracks (channels). You may find small metal or plastic “takeout clips” that can be pushed in or rotated, OR removable wood “stops” or parting beads held by screws or nails.
3. Engage Clips / Remove Stops:
   • Clips: Use a flathead screwdriver to push or rotate the takeout clips according to their design. This widens the channel.
   • Stops: Carefully remove any screws holding the stops, or gently pry them out if they are nailed (score paint lines first).
4. Maneuver Sash Out: With the clips engaged or stops removed, you should be able to carefully push the sash towards one side of the frame, then pull the other side free from the track. Lift the entire sash out.

Place the removed sash carefully on a protected surface.

Removing the Top (Fixed) Sash – Is It Possible?

Важный: On most modern vinyl or fiberglass single-hung windows, the top sash is permanently fixed into the frame. It is NOT designed to be removed independently. Attempting to force it can damage the window frame irreparably.

If you need to remove the top sash on these types of windows (e.g., for replacement), you typically must remove the entire window unit. (See guide on removing the whole window unit).

Exceptions (Less Common):

• Older Wood Windows: Some very old wood single-hung windows мощь have removable stops or parting beads holding the top sash in place, similar to the non-tilt bottom sash method above. This requires careful removal of these wood strips.
• Some Specific Designs: A few specialized designs might allow top sash removal, but this is rare. Check for any visible fasteners or unique mechanisms.

Bottom Line: Assume the top sash is fixed unless you see clear evidence (removable stops, specific fasteners for the sash itself) that it’s designed to come out. Do not pry or force it.

Reinstalling the Window Sashes

Installation is generally the reverse of removal.

Reinstalling the Bottom Sash:

1. Tilt-In Method:
   • Hold the sash horizontally (tilted). Align one pivot bar with its balance shoe in the jamb track and push it firmly into place.
   • Align the second pivot bar with its shoe and push it in.
   • Carefully tilt the sash back up into the vertical position until the tilt latches click back into place.
2. Non-Tilt Method:
   • Angle the sash and insert one side into its jamb track.
   • Maneuver the other side back into its track.
   • Re-engage takeout clips or reinstall any stops/parting beads you removed.
3. Тест: Slide the sash up and down fully. Ensure it moves smoothly and locks correctly.

Reinstalling a (Removable) Top Sash:

• Reverse the specific steps you used for removal (e.g., reinstall stops, secure fasteners). Ensure it’s seated correctly and securely.

When Sash Replacement is Necessary (Ordering New Sashes)

If your sash is cracked, rotted, severely warped, or the sealed glass unit has failed (foggy between panes), simple removal and cleaning won’t suffice. You may need a replacement sash.

• Тщательно измерьте: Accurately measure the height, width, and thickness of your existing sash. Note the material and style.
• Contact Manufacturer/Supplier: Provide measurements and window details (brand/model if known) to order a compatible replacement sash.
• Consider a Full Window Upgrade: If the frame is also old or inefficient, sometimes ordering a complete new custom single-hung window is a better long-term investment than just replacing a sash.

Заключение

Removing the нижняя створка of a single-hung window is usually straightforward using either tilt-latches or takeout clips/stops. However, the top sash is typically fixed and not designed for easy removal. Attempting to force a fixed top sash can damage your window.

Always work safely, and if a sash is damaged beyond simple repair, consider ordering a replacement sash or evaluating if a full window replacement is a better option for your home.
