How to replace the magnetic strip on a magnetic insulated door?

Apr 20, 2026Leave a message

Hey there! As a supplier of Magnetic Insulated Doors, I often get asked about how to replace the magnetic strip on these doors. It might seem like a daunting task, but with the right steps and a bit of know - how, you can do it yourself. In this blog, I'll walk you through the whole process.

Why Replace the Magnetic Strip?

First off, let's talk about why you might need to replace the magnetic strip. Over time, the magnetic strip on your magnetic insulated door can wear out. Maybe the magnets lose their strength, or the strip gets damaged from regular use. When this happens, the door won't seal properly, which means you could be losing heat in the winter or cool air in the summer. That's not good for your energy bills or your comfort.

Tools You'll Need

Before you start, gather the following tools:

  • A utility knife
  • A measuring tape
  • A new magnetic strip (make sure it's the right size for your door)
  • A flat - head screwdriver (if needed for removing the old strip)

Step 1: Measure the Door

The first thing you need to do is measure the length of the area where the magnetic strip is going to be installed. Use your measuring tape to get an accurate measurement. It's important to measure twice to make sure you get the right length for the new magnetic strip. You don't want it to be too short or too long.

Step 2: Remove the Old Magnetic Strip

If the old magnetic strip is held in place by screws, use your flat - head screwdriver to remove them. If it's glued on, you can use a utility knife to carefully cut the glue. Start at one end of the strip and work your way along, being careful not to damage the door. Once the old strip is removed, clean the area where it was attached. You can use a mild cleaner and a cloth to get rid of any glue residue.

Step 3: Prepare the New Magnetic Strip

Take your new magnetic strip and lay it out flat. Check to make sure it's not kinked or bent. If it is, try to straighten it out gently. You can also mark the length on the strip according to the measurement you took earlier. Use a pen or a marker to make a clear mark.

Step 4: Install the New Magnetic Strip

Now it's time to install the new magnetic strip. If the strip has an adhesive backing, peel off the protective paper. Start at one end of the door and carefully press the strip onto the door, following the edge. Make sure it's straight and aligned properly. Use your hands to smooth out any air bubbles as you go. If the strip doesn't have an adhesive backing, you can use a strong adhesive to attach it. Apply the adhesive to the door and then press the strip onto it.

Step 5: Test the Door

Once the magnetic strip is installed, test the door. Close it and see if it seals properly. The magnets should hold the door shut tightly. If there are any gaps or if the door doesn't close properly, you might need to adjust the strip. You can try re - positioning it or adding more adhesive if needed.
