Thresholds play a major role when it comes to making an entry into your home. There are two main types of threshold: exterior & interior threshold: exterior threshold keeps warm air in and cold air out during winter & cold air in & warm air out during summer. Another best thing about the exterior door threshold is that it prevents bugs to appear in your home. As far as the interior threshold is concerned, they create transitions betwixt different types of flooring materials. The thresholds in your home should be durable as well as securely installed, due to the reason that they withstand a lot of traffic. A threshold installed at the bottom of an exterior door usually offers a weather-tight transition betwixt the interior floor and the exterior siding. When it comes to sealing your home in order to protect it from water damage & air infiltration, a threshold plays a crucial role. As you know a door threshold has a lot of foot traffic, so it will get aged or worsen, which in turn makes it look bad. Therefore, the best option is to replace the old door threshold with the new one.
Step By Step Process To Remove & Replace Adjustable Door Threshold
A threshold is the sill plate situated underneath the majority of the exterior entrance doors, betwixt the jambs. Some of the thresholds come with height adjustment screws that will help the weatherstrip over & above the threshold to be lifted, or lowered to meet the underside edge of the door. When you are looking to replace the thresholds, make sure to check that the replacement part is having the same thickness, or height, as the original one in order to maintain weatherproofing and avoid obstructing the door.
- First of all, get rid of the rubber gasket on top of the threshold in order to disclose the adjustment as well as mounting screws. Discover the exact place or position of the mounting screws. These are put down in sunken and adjourned holes, lower than the adjustment screws, and spaced evenly through the threshold. There are mostly three to four mounting screws.
- Now, pull out the mounting screws with the help of a cordless drill and screw tip, turning them anticlockwise to twist them out. Trim through the edges of the threshold with the help of a utility knife to cut any old caulking betwixt the threshold and the floor.
- After that, pry the threshold from the door frame with the help of a large pry bar. Commence by raising one end of the threshold up and tilting it out of the frame. Scrape away any old caulking from underneath the threshold with the help of a paint scraper, before sweeping the installation area in order to get rid of debris.
- Next, place the old threshold on top of the replacement, before tracking down the end profile of the original onto the new threshold. Trim the ends of the new threshold to complement the original one, with the help of a reciprocating saw. Put or spread a quarter-inch bead of silicone caulk through the outside edge on the underside of the threshold. Adjust it into the door jamb and tap it down to the floor. Eliminate the rubber gasket on top of the new threshold.
- Finally, place or fix a 3-inch treated deck screw along each of the mounting screw holes in the threshold. With the help of a screwdriver, adjust the height adjustment screws as long as the top of the threshold is one-eighth of an inch below the underside of the door. Replace the rubber gasket above or over the threshold so that it presses against the underside of the door.
