Proper Procedure Of Removing & Replacing An Aluminum Threshold
A threshold is a kind of strip through the bottom of a door opening that helps seal it when the door is closed, so cold or hot that air does not seep in underneath the door. A threshold can be wood, metal, or vinyl, however, a well-known option is an aluminum, which has some of the advantages over other types of threshold, such as, it is resistant to rot or water damage, cleans easily, as well as it requires no regular maintenance. The majority of the aluminum thresholds consist of rubber strips that flex when the door is closed in order to provide a tighter seal.
Thing's You Will Need
- Tape Measure
- Screwdriver Or Screw Gun
- Pry Bar, Hacksaw & File
- Power Drill & Metal Bit
- Nail Or Pencil
Step 1: Measure The Bottom Of The Doorway
First of all, calculate or compute the underside of the doorway with the help of a tape measure and purchase an aluminum threshold to fit, most entry doors are nearly 36 inches wide. Match the height of the new threshold exactly to the old threshold & make sure that the new threshold is no higher off the floor in order to prevent door closing problems. Use a rubber-centered threshold if in case the old one had such a piece.
Step 2: Find The Mounting Screws On The Existing Threshold
Now, discover the exact place or position of the mounting screws on the existing threshold, generally at each outside end and usually one or two in between. Some aluminum thresholds have screws certainly visible, however, on others, they are hidden underneath the rubber center, which must be pulled off in order to get at the screws. Take out the screws with the help of a screwdriver or screw gun.
Step 3: Remove The Old Threshold Using A Pry Bar
Take out the old threshold, some styles fit betwixt the two side door jambs, while others are mounted underneath the jamb ends. Pull the old threshold out, with the help of a pry bar if necessary in order to release it from underneath the jambs. Clean up any dirt, dust, as well as debris that had collected underneath and around the old threshold.
Step 4: Place The New Threshold On The Floor
Place the new threshold on the floor, using one end flush against one jamb, and mark the other end to be cut. Trim off any excess aluminum with the help of a hacksaw and clean up as well as smooth the cut edge with a file. Mark the location for mounting holes if in case the new aluminum threshold is not predrilled. Drill holes in the aluminum with the help of a power drill and metal bit.
Step 5: Lay The New Threshold In Place
Lay the new threshold in place before using a nail or pencil in order to mark the wood plate underneath the threshold for mounting screws. Take out the threshold before drilling holes in the wood, then put the new threshold back in place and fasten screws with the help of a screwdriver or screw gun. Calculate or compute the threshold mounting holes and mark them on the floor if the ends slide underneath the side jambs, then slide the threshold underneath the jambs and screw it down.
