Replacing a broken window pane can be a daunting task, but it’s actually quite simple if you have the right tools and know-how. The first step is to remove the old pane, and this can be done without damaging the frame or the surrounding glass. Here’s a step-by-step guide on how to do it:

First, you’ll need to gather a few tools. You’ll need a putty knife, a hammer, a screwdriver, and a pair of pliers. You may also want to wear safety glasses and gloves to protect yourself from broken glass.

Once you have your tools, you can start removing the old window pane. First, use the putty knife to carefully remove the putty that is holding the pane in place. Be careful not to damage the frame or the glass. Once the putty is removed, you can use the hammer to gently tap the pane until it loosens. Be careful not to hit the pane too hard, or you could break it.

Identifying the Window Type

The first step in removing a window pane is to identify the type of window you have. There are three main types of windows: single-hung, double-hung, and casement.

Single-Hung Windows

Single-hung windows are the most common type of window. They have a single sash that slides up and down to open and close. The sash is held in place by two tracks on either side of the window frame. To identify a single-hung window, look for the following features:

* A single sash that slides up and down
* Two tracks on either side of the window frame
* A latch at the bottom of the sash to keep it in place

Double-Hung Windows

Double-hung windows have two sashes that slide up and down to open and close. The sashes are held in place by two tracks on either side of the window frame. To identify a double-hung window, look for the following features:

* Two sashes that slide up and down
* Two tracks on either side of the window frame
* Latches at the top and bottom of each sash to keep it in place

Casement Windows

Casement windows have a single sash that is hinged on one side. The sash swings open like a door to open and close. To identify a casement window, look for the following features:

* A single sash that swings open like a door
* Hinges on one side of the window frame
* A latch at the top or bottom of the sash to keep it in place

Window Type Sash Tracks Latches
Single-Hung Single 2 1
Double-Hung 2 2 2
Casement Single 0 1

Selecting the Appropriate Tools

Choosing the correct instruments is important for a smooth process. Here are the specific tools you will require:

Essential Tools for Removing a Window Pane

A putty knife is crucial for loosening the glazing compound that holds the glass pane in place. Select a putty knife with a blade that is sharp enough to cut through the compound but not so sharp that it damages the wood frame.

A hammer is necessary to gently tap the putty knife as you pry off the glazing compound. A rubber mallet is ideal as it is less likely to damage the window frame.

A suction cup is an optional tool that can make the removal process easier. By attaching the suction cup to the glass pane, you can safely apply pulling force to lift the pane out of the frame.

Additionally, consider using safety glasses and gloves for protection during the process.

Tool Usage
Putty Knife Loosening glazing compound
Hammer Tapping putty knife to remove compound
Suction Cup (Optional) Lifting glass pane from frame
Safety Glasses Eye protection
Gloves Hand protection

Removing the Window Sash

To remove the window sash, you will need to first remove the stop molding that holds it in place. The stop molding is typically nailed or screwed into the frame of the window, and can be removed using a pry bar or a screwdriver. Once the stop molding has been removed, you will be able to lift the window sash out of the frame.

Removing the Window Sash

To remove the window sash, follow these steps:

1. Locate the stop molding that holds the sash in place. The stop molding is typically nailed or screwed into the frame of the window, and can be removed using a pry bar or a screwdriver.

2. Carefully pry the stop molding away from the frame of the window. Be careful not to damage the stop molding or the frame of the window.

3. Once the stop molding has been removed, you will be able to lift the window sash out of the frame. Be careful not to drop the sash, as it could be heavy.

Here is a table summarizing the steps for removing the window sash:

Step Description

2 Carefully pry the stop molding away from the frame of the window.
3 Once the stop molding has been removed, you will be able to lift the window sash out of the frame.

Cutting the Glazing Compound

The glazing compound is a pliable substance that holds the window pane in place and seals it against the elements. It is typically made of linseed oil, chalk, and pigment.

  1. Safety first! Wear safety glasses and gloves before you begin.
  2. Choose the right tool: A putty knife or a razor blade can be used to cut the glazing compound.
  3. Position the blade: Hold a putty knife on a 45-degree angle and keep it close to the glass to avoid scratching it.
  4. Cut the compound: Slowly cut along the edges of the window pane, taking care not to damage the glass or the wood frame. Follow the tips below for different glazings:

Types of Glazing Compound and Removal Techniques:

Compound Type Removal Technique
Soft Glazing Use a putty knife to gently pry the compound away from the glass.
Hard Glazing Score the compound with a razor blade and then use a chisel to break it apart.
Oil-Based Glazing Apply heat with a heat gun to soften the compound before cutting.

Separating the Pane from the Sash

Once you’ve removed the fasteners that were holding the sash in place, you can begin to separate the pane from the sash.

Step 1: Remove the glazing points. Glazing points are small, triangular wedges that are used to hold the glass in place. They are typically made of wood or plastic and are located along the edges of the sash.

To remove the glazing points, use a putty knife or a thin-bladed screwdriver. Gently pry the glazing points out and remove them from the sash.

Step 2: Loosen the putty. Putty is a type of sealant that is used to hold the glass in place. It can be loosened with a putty knife or a knife.

Run the knife around the edges of the glass to loosen the putty. Be careful not to scratch the glass.

Step 3: Remove the glass. Once the putty has been loosened, you can remove the glass.

Gently lift the glass out of the sash. Be careful not to drop or break the glass.

Step 4: Clean the sash and the glass. Once the glass has been removed, you can clean the sash and the glass.

Step 5: Replace the glass. To replace the glass, follow these steps in reverse order:

    Apply a bead of putty to the edges of the sash. Gently place the glass into the sash. Press the glazing points into the sash to secure the glass. Wipe away any excess putty.

Inserting the New Pane

Now that the old pane has been successfully removed, it’s time to install the new one. Follow these steps carefully to ensure a secure and precise fit:

  1. Clean the Frame: Remove any broken glass or debris from the window frame, ensuring it’s clean and free of obstructions.
  2. Apply Glazing Compound: Run a generous bead of glazing compound around the exterior perimeter of the frame where the pane will be fitted.
  3. Insert the Pane: Carefully place the new glass pane within the frame, aligning it with the edges.
  4. Press In: Use a glazing tool or wooden block to gently press the pane into the glazing compound, ensuring it’s flush with the frame.
  5. Trim Excess Compound: Remove any excess glazing compound that oozes out by using a putty knife or razor blade.
  6. Smooth the Edges: Smooth the edges of the glazing compound with your finger or a wet cloth to create a clean and professional finish.
  7. Secure the Pane: To enhance the stability of the new pane, drive small galvanized nails or glazing points through the frame and into the edge of the glass at regular intervals.

Glazing the New Pane

After the old pane has been removed, you need to prepare the new one for installation. The following steps will guide you through the glazing process:

1. Measure the Opening: Measure the height and width of the window opening to determine the exact dimensions of the new pane.

2. Cut the Pane: Using a glass cutter, carefully cut a new pane of glass to match the measurements you took.

3. Clean the Edges: Wear gloves for this step. Use a damp cloth or a putty knife to remove any debris or dust from the edges of the new pane.

4. Apply Glazing Compound: Take a glazing compound (preferably an oil-based one) and apply it generously to the rabbet (the groove on the frame where the pane sits).

5. Insert the Pane: Position the new pane into the rabbet, making sure it is centered and aligned with the frame.

6. Secure the Pane: Press the pane gently into the glazing compound, applying even pressure to all sides.

7. Trim Excess Compound: Use a putty knife to trim away any excess glazing compound that has squeezed out.

8. **Smoothing the Glazing Compound:**

Tool Action
Smooth Face Trowel For a smooth and even finish, use a smooth-faced trowel to press down and spread the glazing compound.
Bradley Knife For a more professional look, use a Bradley knife to cut a clean and precise line of glazing compound, giving your window a finished appearance.

Reinstalling the Sash

9. Installing the Sash

Now that the pane has been replaced, you can reinstall the sash. Install the aluminum guides back into the top and bottom tracks of the window frame, ensuring that they sit flush with the frame. Next, fit the sash back into the tracks, starting from the bottom and then snapping the top into place. Make sure both sides of the sash are evenly installed, and check that it moves up and down smoothly within the tracks.

Reattach the stops to the window frame using either nails or screws. The stops should fit snugly against the sash to keep it in place. Finally, reinstall the windowsill if it was removed.

As a reminder, here’s a step-by-step guide to reinstall the sash:

Step Action
1 Insert the aluminum guides back into the window frame.
2 Fit the sash into the bottom tracks and snap it into the top ones.
3 Reattach the stops to secure the sash.
4 Replace the windowsill.

Applying Weatherstripping and Trim

10. **Install Weatherstripping between the Window Sash and Frame:**

Type Installation
Felt Weatherstripping Nail or staple into the frame; tuck into the sash groove
Foamed Weatherstripping Peel and stick to the frame or sash
V-Shaped Weatherstripping Insert into the gap between the sash and frame
Magnetic Weatherstripping Attach magnetic strips to the sash and frame; they will seal together

a) Apply weatherstripping to all four sides of the sash, starting from the top.
b) Ensure the weatherstripping makes full contact with the frame and sash.
c) Trim any excess weatherstripping.
d) Check the fit and seal by closing the window and inspecting for gaps.

11. **Install Window Trim:**
a) Measure and cut the trim pieces to fit around the window frame.
b) Apply adhesive or nails to the back of the trim.
c) Press the trim into place and secure it.
d) Fill any gaps between the trim and the wall or frame with caulk.
