Closing the Gap: How to Fix the Space Between Your Door and Frame

Closing the gap between your door and frame is important for various reasons, including energy efficiency, security, and aesthetics. Here’s a step-by-step guide on how to fix the space between your door and frame:

Materials You’ll Need:

  1. Weatherstripping: Choose either adhesive-backed foam weatherstripping, V-strip, or door sweeps depending on the size of the gap.
  2. Measuring Tape: To measure the size of the gap accurately.
  3. Utility Knife: For cutting weatherstripping and other materials.
  4. Screwdriver: To remove or adjust screws in the door or frame, if necessary.
  5. Caulk (optional): For sealing any gaps or cracks in the frame.


Measure the Gap: Start by measuring the gap between your door and the frame. Measure at various points along the door’s perimeter, as gaps may not be uniform.

Choose Weatherstripping Type: Depending on the size and shape of the gap, select the appropriate weatherstripping material:

  • For small gaps: Use adhesive-backed foam weatherstripping or V-strip.
  • For larger gaps at the bottom: A door sweep is usually effective.

Clean the Surface: Ensure both the door and the frame are clean and free of dust or debris. Use a damp cloth to wipe down the surfaces.

Install Weatherstripping:

  • Adhesive-backed Foam Weatherstripping:
    1. Cut the weatherstripping to the required length using a utility knife.
    2. Peel off the backing and apply the weatherstripping to the frame or the door jamb, depending on where the gap is.
    3. Press firmly to ensure it adheres securely.
  • V-Strip:
    1. Cut the V-strip to match the length of the gap.
    2. Insert the V-strip into the gap, pushing it in with a putty knife or your fingers.
  • Door Sweep:
    1. Close the door and measure the width of the door.
    2. Cut the door sweep to match the width of the door.
    3. Attach it to the bottom of the door following the manufacturer’s instructions.

Adjust the Door Hardware (if needed): If the gap is still not adequately sealed, you may need to adjust the door hardware. Loosen the screws on the hinges, the strike plate, or the latch plate slightly and reposition the door so that it fits more snugly. Tighten the screws once you’ve made the necessary adjustments.

Seal Any Cracks or Gaps in the Frame (optional):

If there are cracks or gaps in the frame itself, you can use caulk to seal them. Apply caulk to the gaps, and then smooth it out with a caulk tool or your finger. Allow it to dry before testing the door again.

Test the Door:

After you’ve installed the weatherstripping and made any necessary adjustments, test the door to ensure it closes securely and seals properly. You should not feel any drafts or see any light coming through the gap.

Fixing the space between your door and frame is an effective way to improve energy efficiency, increase security, and enhance comfort in your home. It’s a relatively simple DIY project that can make a noticeable difference.
