Refresh Window Frames: Remove, Repaint, Revitalize

Window pane dividers are a great way to add an element of class and interest to your windows. However, over time, you may want to modernise your space and remove them. This can be done by identifying the type of material your window pane dividers are made of, gathering the right tools, and carefully removing them. Once removed, you can paint your windows and allow them to dry. Finally, you can choose to reinstall new window pane dividers or enjoy the cleaner and simpler look of your windows without them.

Identify the type of window pane divider

To identify the type of window pane divider, it is important to understand the different terms used to describe these features and their functions. Here is a detailed guide to help you identify the type of window pane divider:

Muntins

Muntins, also known as muntin bars, glazing bars, or sash bars, are strips of wood or metal that separate and hold panes of glass in a window. They are commonly found in windows, doors, and furniture, especially in Western architectural styles. Muntins divide a single window sash or casement into a grid system of smaller panes of glass, often referred to as "lights" or "lites". The thickness of muntins can vary, with thinner muntins typically used in residential windows to create "true divided lights". In the past, muntins served a structural purpose by distributing the weight of large windows, but today they are primarily used for aesthetic purposes.

Mullions

Mullions are vertical or horizontal structural pieces that combine two or more windows together. They are typically heavier elements that divide larger window frames and can create the appearance of multiple windows. Mullions were historically used to support smaller panes of glass before the industrial revolution made large panels of glass widely available.

Grilles

Grilles are decorative pieces that visually divide window panels, giving the glass the appearance of multiple panes. They are often used in modern windows to create a grid-like pattern for aesthetic purposes. Grilles can be permanently affixed between panes of insulated glass or added as removable pieces on the outside of the glass.

Stiles

Stiles are the outer vertical pieces of a window frame that, along with rails, form the framework of the window. They are distinguished from muntins, which are the inner vertical dividers between panes of glass.

Rails

Rails are the horizontal pieces of a window sash that, together with stiles, create the framework for the glass panes. They include the lower rail, check rail (middle of the window), and upper rail.

When identifying the type of window pane divider, consider the placement, function, and aesthetic of these different components. Muntins, mullions, grilles, stiles, and rails all play a role in dividing and supporting window panes, each with unique characteristics and purposes.

Gather the right tools and materials

To remove false window pane dividers, you will need to gather the right tools and materials. The specific tools and materials you will need will depend on the type of material your window pane dividers are made of, which is usually vinyl, wood, or aluminum.

If your window pane dividers are made of vinyl, you will need a straight edge or box cutter, double-sided tape or Velcro, and a soft cloth. You may also need a putty knife to help remove the dividers, as well as window cleaner to clean the window before and after the removal process.

For wood window pane dividers, you will need a screwdriver or putty knife to remove the grille, as well as a silicone sealant, screws, double-sided tape, or Velcro to secure the new or repaired grille. If the wood is damaged, you will also need a saw to cut a new piece to size.

Aluminum window pane dividers are the most durable option and can be removed with a screwdriver or by releasing the adhering agent. To repair or replace aluminum dividers, you will need metal-cutting shears, a file, a measuring tape, and metal-adhering glue.

In addition to the above tools and materials, it is recommended to wear gloves while working on this project to protect your hands.

Remove the entire grid of dividers

Removing the entire grid of window pane dividers is a straightforward process, but it requires care and patience. Here is a step-by-step guide:

• Begin by gathering the necessary tools and materials. You will need an electric drill, a screwdriver, a chisel, a pry bar, a soft cloth, and window cleaner. It is also recommended to wear gloves for protection.
• Clean the window thoroughly to remove any dirt, debris, or grime. Spray the window cleaner on both sides of the window and use a soft cloth to wipe it down in circular motions until it is clean and free of smudges.
• Inspect the window to identify the screws or nails holding the grids in place. Exterior grids are typically secured with nails, while vinyl grilles may be attached within the double pane using screws.
• If your window has exterior grids, use a hammer to carefully remove the nails. For vinyl grilles attached with screws, use a drill with a small Phillips head screwdriver to remove them.
• Once the screws or nails are removed, use a chisel and pry bar to gently loosen any remaining adhesive or caulk holding the grids in place. Be cautious to avoid damaging the window frame during this process.
• After removing the grids, clean the window again with a soft cloth. If there is any adhesive residue on the glass, use a common household cleaner, such as Windex, to remove it.
• At this point, you have successfully removed the entire grid of window pane dividers. You can now proceed with painting the window or making any other desired modifications.

Remember to work carefully and patiently throughout the process to ensure that you do not damage the window or its frame. If you are unsure or uncomfortable with any part of the process, consider seeking the help of a professional window repair and replacement expert.

Measure the length of the replacement divider

To measure the length of the replacement divider, start by examining the window to identify the screws or nails holding the grids in place. If your window has exterior grids, they are typically secured with nails, while vinyl grilles attached within the double pane usually have screws. Once identified, use a small Phillips-head screwdriver to remove the screws. If your grids are secured with nails, carefully use a hammer to remove them.

After removing the screws or nails, you can now take measurements for the replacement divider. Use a measuring tape to measure the exact length and width of the divider you need to replace. Make sure to measure the space between the window panes where the new divider will be installed.

It is important to take accurate measurements to ensure a proper fit for your replacement divider. Consider taking measurements at least twice to confirm accuracy. You can also measure the old divider that you removed to compare dimensions and ensure consistency.

Additionally, if your window has any unique features or shapes, make sure to account for those when measuring. You may need to measure the height and depth of the space as well, especially if your replacement divider needs to be custom-made or ordered.

By taking precise measurements, you can ensure that your replacement divider fits securely and aligns correctly with the window panes. Accurate measurements will also help you source the appropriate materials or find a suitable replacement divider that matches the specific dimensions of your window.

Reattach the divider and clean the window

Once you have painted the window pane dividers, it is time to reattach them to the window. If you are working with vinyl, carefully cut the vinyl to the desired length with a straight edge or box cutter. Insert the vinyl into the grid and attach new Velcro or double-sided tape to the repair piece. For wooden dividers, you can use a putty knife to pry the grid out of the window frame. If the damage is repairable, use a silicone sealant to adhere the piece to the window frame and replace the screws. If the area is completely broken, you may need to mill a new replacement piece. For aluminium dividers, use metal-cutting shears to remove the damaged section and file down any sharp or jagged edges. Measure the amount of material needed to replace the damaged area and use metal-adhering glue to attach the new bar to the existing grid.

After you have reattached the divider, it is important to clean the window. Use a soft cloth and a window cleaner to wipe down the window in circular motions until it is free from dirt and smudges. Clean both sides of the window pane to remove all grime. If there is any adhesive residue on the glass, use a common household cleaner, such as Windex, to remove it.
