6 Steps on How to Replace a Door Threshold

A door threshold is a crucial, often overlooked component that protects the interior of your home from the elements. Over time, wear and tear, moisture damage, or shifting foundations can compromise its integrity, necessitating replacement. Replacing a door threshold may seem like a daunting task, but with the right tools and a few simple steps, it’s a manageable DIY project that can enhance the functionality and aesthetics of your home. In this comprehensive guide, we will walk you through the process of removing the old threshold, preparing the opening, and installing a new one.

To begin, gather the necessary materials: a new door threshold, a pry bar or utility knife, a hammer, a level, a tape measure, wood glue, and nails or screws. Ensure the new threshold matches the dimensions of the existing one and choose a material that complements the style of your home. Once you have your materials ready, clear the area around the door of any obstructions and remove the door to provide ample workspace. Next, carefully insert the pry bar or utility knife underneath the old threshold and gently pry it loose from the floor. If the threshold is particularly stubborn, you may need to use a hammer to tap the pry bar and loosen the adhesive.

With the old threshold removed, it’s time to inspect the subfloor underneath. If there is any damage or rot, it should be repaired or replaced before installing the new threshold. Clean the area thoroughly to remove any debris or old adhesive. Measure the opening and mark the dimensions of the new threshold onto the subfloor using a pencil or chalk. Apply a generous bead of wood glue to the bottom of the new threshold and carefully align it with the markings on the subfloor. Secure the threshold in place by driving nails or screws through the pre-drilled holes and countersinking the heads slightly below the surface. Ensure the threshold is level by using a spirit level and adjust it as needed. Allow the wood glue to dry completely before replacing the door and enjoying your newly installed threshold.

Removing the Old Threshold

Step 1: Remove Trim and Sill

Start by carefully removing the trim pieces on both sides of the threshold. Use a pry bar or a flathead screwdriver to gently lift the trim away from the wall and floor, taking care not to damage the surrounding surfaces. Then, remove the sill, which is the horizontal piece of wood under the threshold, by unscrewing it or pulling it out from the door frame.

Step 2: Remove Nails or Screws

Once the trim and sill are removed, you’ll need to remove the nails or screws that are holding the threshold in place. Use a nail puller or a screwdriver to carefully extract them. If you encounter any stubborn nails or screws that refuse to budge, try using a penetrating oil or lubricant to loosen them up before removing them.

Step 3: Remove the Threshold

With the nails or screws removed, you should now be able to lift the threshold up and out of the door frame. If it’s stuck, use a pry bar to gently pry it loose. Once the threshold is removed, clean the area around the door frame to remove any remaining debris or old adhesive.

Preparing the Doorway

Before you can begin replacing the threshold, you need to prep the doorway. This involves removing the old threshold and any other obstructions, such as weatherstripping or caulk.

Removing the Old Threshold

  1. Score the threshold with a utility knife. This will help you to snap it in half when you’re ready to remove it.
  2. Carefully pry the old threshold loose from the doorway. Use a pry bar or a flathead screwdriver to do this.
  3. Check for nails or screws that are holding the threshold in place. If you find any, remove them with a hammer or a screwdriver.
  4. Once the old threshold is loose, snap it in half and remove it from the doorway.

Cleaning the Doorway

Once the old threshold is removed, you need to clean the doorway. This will help to ensure that the new threshold will adhere properly.

  1. Remove any debris from the doorway. This includes dirt, dust, and old caulk or weatherstripping.
  2. Sweep or vacuum the doorway. This will help to remove any loose debris.
  3. Wipe down the doorway with a damp cloth. This will help to remove any remaining dirt or dust.

Leveling the Doorway

Once the doorway is clean, you need to level it. This will help to ensure that the new threshold will be installed properly.

  1. Place a level on the doorway. This will help you to determine if the doorway is level.
  2. If the doorway is not level, you will need to shim it. Shims are thin pieces of wood that can be used to level the doorway.
  3. Insert the shims under the doorway until it is level. Once the doorway is level, you can proceed to install the new threshold.

Cutting and Fitting the New Threshold

Once you have removed the old threshold, it is time to cut and fit the new threshold. To do this, you will need to first measure the width of the door opening. Then, cut the new threshold to the correct length.

Next, you will need to fit the new threshold into the door opening. To do this, place the threshold in the opening and align it with the door frame.

Then, use a hammer to tap the threshold into place. Be sure to tap the threshold evenly so that it does not become damaged.

Finally, you will need to secure the threshold in place. To do this, you can use nails or screws. If you are using nails, be sure to predrill the holes first to avoid splitting the threshold.

Step-by-Step Instructions for Cutting and Fitting the New Threshold:

Step Instructions
1 Measure the width of the door opening.
2 Cut the new threshold to the correct length.
3 Place the threshold in the opening and align it with the door frame.
4 Use a hammer to tap the threshold into place. Be sure to tap the threshold evenly so that it does not become damaged.
5 Secure the threshold in place with nails or screws.

Securing the Threshold into Place

To ensure your new threshold is secure and does not shift or come loose during use, follow these steps carefully:

1. Applying Adhesive

Use an exterior-grade adhesive specifically formulated for thresholds. Apply a generous bead of adhesive along the length of the threshold, ensuring an even distribution and no gaps. Press the threshold firmly into place, ensuring it aligns properly with the jambs.

2. Installing Screws

Use corrosion-resistant screws compatible with your threshold material. Pre-drill countersink holes along the threshold at regular intervals. Drive the screws through the holes and into the subfloor or jambs, ensuring they are snug but not overtightened.

3. Adding a Drip Edge

If the threshold extends beyond the jambs, install a drip edge to prevent water from seeping underneath. Apply adhesive to the underside of the drip edge and press it into place along the edge of the threshold. Secure it further with screws or nails.

4. Applying Caulk

Use a flexible exterior-grade caulk to seal any gaps or cracks around the threshold. Apply the caulk around the perimeter of the threshold, ensuring it fills any imperfections or transitions between the threshold and the jambs. Smooth the caulk with a damp finger or caulk tool.

5. Enhancing Stability

For increased stability, consider using threshold expansion anchors. These devices insert into the holes pre-drilled for screws and anchor the threshold securely to the subfloor. Expansion anchors are particularly beneficial for high-traffic areas or doors prone to heavy use.
