How do you put plastic over a broken window?

Published in Temporary Window Repair 3 mins read

To put plastic over a broken window, you will measure the window, cut the plastic with extra material, and secure it tightly around the frame using tape. This provides a temporary seal against the elements.

Putting plastic over a broken window is a common temporary fix to prevent drafts, moisture, and debris from entering your home or building until permanent repairs can be made. It's a relatively simple process that requires just a few basic materials.

Materials Needed

Before you begin, gather the following items:

  • Heavy-duty plastic sheeting: Ensure it's thick enough to withstand wind and weather.
  • Measuring tape: To get accurate window dimensions.
  • Scissors or utility knife: For cutting the plastic.
  • Strong adhesive tape: Duct tape, packing tape, or specific window sealing tape works well.
  • Gloves: To protect your hands from broken glass.
  • Safety glasses: To protect your eyes.
  • Optional: A broom and dustpan for initial cleanup of large glass shards.

Step-by-Step Guide to Covering a Broken Window

Here is a simple process to temporarily cover a broken window with plastic, incorporating the essential steps:

  1. Safety First: Carefully remove any large, loose pieces of glass from the frame, wearing gloves and safety glasses. Dispose of them safely.
  2. Measure the Window: Use your measuring tape to get the height and width of the window frame opening.
  3. Cut the Plastic: Measure the size of your window and cut the plastic, leaving half-inch extra on all sides. This extra material gives you a margin for error and makes it easier to secure the edges.
  4. Attach the Plastic: Carefully position the cut plastic over the broken window area on the outside of the frame if possible.
  5. Secure with Tape: Secure it around the frame with tape, ensuring it's pulled taut to avoid gaps. Start taping along one edge, pulling the plastic firmly as you go to minimize sagging and wrinkles. Tape all four sides, overlapping tape edges for a strong seal.
  6. Check for Gaps: Once taped, visually inspect all edges to ensure the plastic is sealed completely against the frame. Add more tape where necessary to block any drafts or potential water entry points.

By following these steps, you create a temporary barrier that helps maintain indoor comfort and protects the interior from weather until the window can be properly replaced or repaired.
