How To Replace Door Threshold

If you have a damaged or worn-out door threshold, it’s important to replace it as soon as possible. A damaged threshold can cause drafts and energy loss, leading to higher heating and cooling bills. Moreover, it can also pose a safety hazard, as it can become slippery and cause accidents. In this article, we’ll show you how to replace door threshold step-by-step.

Step 1: Remove the Old Threshold

The first step in how to replace door threshold is to remove the old one. Start by prying off the rubber gasket that seals the threshold to the door frame. Then, using a pry bar or flathead screwdriver, remove any screws or nails that are holding the threshold in place. Once the screws or nails are removed, you should be able to lift the threshold out of the door frame.

Step 2: Clean the Area

With the old threshold removed, it’s time to clean the area where the new threshold will be installed. Use a scraper or putty knife to remove any old adhesive or debris. Make sure the area is clean and free of any obstructions.

Step 3: Measure and Cut the New Threshold

Now that the area is clean, it’s time to measure and cut the new threshold. Use a tape measure to measure the length and width of the door frame, and then transfer these measurements to the new threshold. Use a circular saw or handsaw to cut the threshold to the correct size.

Step 4: Install the New Threshold

With the new threshold cut to size, it’s time to install it. Apply a generous amount of adhesive to the bottom of the threshold, and then carefully place it into the door frame. Use screws or nails to secure the threshold in place. Be sure to check that the threshold is level before securing it.

Step 5: Install the Rubber Gasket

The final step in how to replace door threshold is to install the rubber gasket. Apply a small amount of adhesive to the bottom of the gasket, and then carefully press it into place along the edge of the threshold. Be sure to press the gasket firmly into place to ensure a good seal.

A: You’ll need a pry bar or flathead screwdriver, a tape measure, a circular saw or handsaw, screws or nails, adhesive, and a rubber gasket.
