Removing old strips

Removing old plastic window strips is a straightforward process, but it does require some care and patience. Here is a step-by-step guide to help you through the process:

  • Safety First: Put on safety glasses and work gloves to protect yourself from any sharp edges or debris.
  • Remove Short Pieces First: Start by removing the short pieces of glazing first. Work on one corner at a time.
  • Pry Gently: Insert the tip of a screwdriver under the top edge of the plastic glazing, where it meets the side of the window frame. Gently pry and dislodge the raised lip of the glazing from its channel in the frame.
  • Slide and Pop: Slide the screwdriver blade down the length of the frame gently. The glazing should pop free from the side channel.
  • Peel Away: Once the glazing is free from the channel, carefully peel it away from the window and out of the frame.
  • Repeat: Repeat the process for the remaining three pieces of glazing. Set the old pieces aside, as they can be used as a reference for cutting new glazing.
  • Clean and Prepare: If you're replacing a broken or damaged window, remove any remaining glass and loose debris from the window frame. Measure the opening to obtain a replacement. If the window is not damaged, simply clean any dirt or debris from the edges with glass cleaner and paper towels.
  • Reference for New Glazing: The old glazing pieces can be used as a guide for cutting new glazing to ensure a proper fit.

Remember to work carefully and take your time, especially when dealing with broken glass or sharp edges. Always follow the window manufacturer's instructions and safety guidelines when performing any window maintenance or repairs.

Trimming the pieces

First, remove the short pieces of glazing. Starting at one of the corners, insert the tip of a screwdriver under the top edge of the plastic glazing where it meets the side of the window frame. Gently pry out to dislodge the raised lip of the glazing from its channel in the frame. Slide the screwdriver blade down the length of the frame until the glazing pops free from the side channel, then peel it away from the window and out of the frame. Repeat this process for the remaining three pieces of glazing.

Next, you will need to cut four pieces of replacement glazing from suitable lengths of new stock with the same profile, using a sharp utility knife and the old pieces as a guide. If you are buying replacement glass, have it cut 1/8-inch smaller than the opening in both length and width. When shopping for new glazing strips, take a piece of the old glazing with you to make sure you get the right profile.

Finally, install the long pieces of glazing first. Place the narrow bottom edge of the glazing against the glass and slide the wider top edge toward the window frame. Starting in one corner, slip the bottom lip of the glazing into the lower groove in the frame next to the glass edge, then tuck the wider portion of the glazing under the top edge of the frame with a rolling motion. Hold the glazing in place at that corner with one hand while sliding the fingers of your other hand along the top edge of the plastic strip toward the opposite corner, snapping the glazing into place in the frame as you go. Install the short pieces of glazing in the same manner, carefully fitting the trimmed corners as you snap the pieces into place. You may need to fine-tune the fit with a utility knife. Tilt the window up on one edge and push on it from the back side to ensure the glass is held securely in place.

Installing long pieces

When installing the long pieces of glazing, start by placing the narrow bottom edge of the glazing against the glass and sliding the wider top edge toward the window frame. Begin in one corner, slipping the bottom lip of the glazing into the lower groove in the frame next to the glass edge. Then, with a rolling motion, tuck the wider portion of the glazing under the top edge of the frame.

Hold the glazing in place at that corner with one hand, and with the other hand, slide your fingers along the top edge of the plastic strip toward the opposite corner. As you do this, the glazing will snap into place in the frame. It is important to note that trimming the pieces to fit may take some practice.

If you are replacing a broken window, ensure that you remove any loose glass from the window frame. When installing the new glazing, it is a good idea to wear safety glasses and work gloves for protection.

Once the long pieces are installed, you can move on to installing the short pieces of glazing. Fit the trimmed corners carefully as you snap the pieces into place. You may need to make adjustments with a utility knife to ensure a secure fit. Finally, tilt the window up on one edge and push on it from the back to ensure that the glass is held securely.

Installing short pieces

When you are ready to install the short pieces, carefully fit the trimmed corners as you snap the pieces into place. You may need to make some adjustments with a utility knife to ensure a perfect fit. It is important to be patient during this process and not rush the installation.

Before installing, make sure you are wearing safety glasses and work gloves for protection. It is also crucial to remove any loose glass from the window frame if you are replacing a broken window. Place the window frame on a flat, padded surface, such as a table covered with a towel or blanket, to avoid damaging the glass or the frame.

Once the short pieces are securely in place, tilt the window up on one edge and push on it from the back to ensure the glass is held securely. Adjust the fit of the glazing strips if needed. Finally, reinstall the window frame and clean both sides of the glass to complete the installation.

Adjusting the fit

First, it is important to understand the mechanism of how the glazing strips are held in place. Glazing strips snap into channels on the window frame, securing the glass in place. When installing new glazing strips, it is common to need to trim the pieces to achieve a precise fit. This step requires some practice to perfect, so don't be discouraged if your first attempts are not perfect.

When adjusting the fit, always put on safety glasses and work gloves to protect yourself from sharp edges and debris. Start by removing the short pieces of glazing first. Gently pry out the top edge of the plastic glazing from the window frame using a screwdriver. Slide the screwdriver blade along the length of the frame to release the glazing from the channel. Repeat this process for all the short pieces.

Use the old pieces of glazing as a reference for trimming the new glazing strips. Measure the opening and obtain replacement glass if needed. Cut the new glazing strips to the required size using a sharp utility knife, ensuring straight and precise cuts. It is recommended to have the replacement glass cut 1/8-inch smaller than the opening in both length and width to allow for any minor adjustments during installation.

When installing the new glazing strips, start with the long pieces first. Place the narrow bottom edge of the glazing against the glass and slide the wider top edge toward the window frame. Use a rolling motion to tuck the wider portion of the glazing under the top edge of the frame. Hold the glazing in one corner while snapping the rest of the piece into place along the frame. Repeat this process for the short pieces, carefully fitting the trimmed corners as you go.

Finally, fine-tune the fit by tilting the window and pushing on it from the backside to ensure the glass is securely held. Make any necessary adjustments with a utility knife to ensure a snug fit. Reinstall the window frame in the jambs and clean both sides of the glass to complete the installation process.
