We start with showing our old worn-out threshold at our front door. We go over why it needs to be replaced. In our case, we had new hardwood floors installed and the door was cut off to accommodate the floor being higher. However the people that installed the floor and cut the door, did not raise the threshold. As a result we had about a 3/4 inch gap from the threshold to the bottom of the door. This was letting a LOT of cold air in (and hot in the summer) and insects year round. The threshold also needed replacing because it was old and worn out.

Next we show how to remove the old threshold. In our case there were only three screws. They are hidden under the rubber strip that is supposed to contact the bottom of the door. The screws are the only thing holding the threshold in place. It may take a little work but it should come up at this time.

Next we show show how we built up the base to accommodate the higher floor. We used 2 layers of 1/4 inch plywood cut to fit. Then trimmed the new threshold to fit the opening. Before installing the threshold, we painted the base so it would look better. Then we installed the aluminum base of the threshold. Next is what may be the hardest part is to install the rubber strip that contacts the bottom of the door to make the seal. We will demonstrate the best way to install it. This is the part that most people find to be the most challenging. With a little guidance, it is not too hard to install.

Then we show the finished threshold and show how well is seals. In our case there was a very small gap on the left side and we later added a small shim to adjust that. In the end we had a new threshold that looked and worked much better.
