How To Install Interior Door Threshold

A door threshold is a strip of material that is installed at the bottom of a door, typically made of wood, metal, or plastic. It serves several important purposes: - Prevents drafts and air leaks from entering or exiting the room. - Blocks dust, dirt, and moisture from entering the room. - Helps to level the floor and provide a smooth transition between rooms. - Provides a decorative touch to the doorway. Installing a door threshold is a relatively simple project that can be completed in a few hours. Here are the steps on how to install an interior door threshold: ### 1. Measure and Cut the Threshold - Measure the width of the door opening. - Add 1 inch to the measurement and cut the threshold to the desired length. ### 2. Prepare the Doorway - Remove the old threshold, if there is one. - Clean the area where the threshold will be installed. - If the floor is uneven, level it out using a self-leveling compound. ### 3. Apply Adhesive to the Threshold - Apply a thin line of construction adhesive to the bottom of the threshold. - Make sure to apply the adhesive evenly. ### 4. Install the Threshold - Carefully place the threshold in the doorway. - Press the threshold down firmly into the adhesive. - Use a level to make sure the threshold is level. ### 5. Secure the Threshold - Drive nails or screws through the threshold and into the subfloor. - Countersink the nails or screws so that they are flush with the surface of the threshold. ### 6. Caulk the Threshold - Apply a bead of caulk to the seam between the threshold and the floor. - Use a paintable caulk that matches the color of the threshold. - Smooth out the caulk with a putty knife. ### 7. Allow the Adhesive and Caulk to Dry - Allow the adhesive and caulk to dry completely before using the door. - This may take 24 hours or more. ### Additional Tips: - When choosing a threshold, consider the type of flooring in your home. - If you have hardwood floors, you will need to use a threshold that is specifically designed for hardwood floors. - You can also purchase thresholds that are pre-finished to match your existing flooring. - If you are installing a threshold in a high-traffic area, you should choose a threshold that is made of a durable material, such as metal or plastic. - Be sure to measure the thickness of your door before you purchase a threshold. - You will need to choose a threshold that is the same thickness as your door.
