Exterior door trim for your storm door is something that is very important. It not only is necessary for an aesthetic reason but is also important to make sure that your door is able to do its job properly. A storm door needs to be as strong as possible. You will be able to have a very strong storm door if you have the proper trim installed surrounding it.
Step 1 – Prepare
The first thing that you are going to have to do is get the jamb prepared for the frame. In order to do this, you will need to pay attention to how the door jamb is laid out. Look to see if your door jamb is flush with your frame or if it sticks out past your frame. You will find that the jamb is most often flush with the siding.
Step 2 – Flash to Frame
Once you have a good idea of where your door jamb is and where it needs to be, you are now ready to get your jamb flashed to the frame. It is best for you to use flashing paper so that you can draft stop your jamb up to the frame. Get the sides stapled to your jamb as well as to the frame. Make sure that the paper that you use is going to be behind your trim to allow for finish caulking. Also, you will need to flash the top of your jamb and make sure that it is over your paper on all of the sides.
Step 3 – Scribe
You are now ready to get the margin scribed onto the jamb. You will need to get a guide so that you can properly do this. It is a good idea for it to be anywhere from ¼ to 3/8” away from the actual opening. This is where you will want your new trim to attach itself. Get your lines connected along the top corners as you go.
Step 4 – Cut Material
Make sure that you square up the trim piece that you are going to cut on onside of it before you attempt to measure it to cut. Cut your piece on one side of it for the jamb from your top line all the way down to the bottom of the siding and then add ½”. Dry fit your trim onto the jamb. Go from the top of it down and check the door threshold as you go. Tap the side of your trim with a hammer so that you can indent the cut of it for your threshold.
Step 5 - Install
Install the trim with screws. Drill a pilot hole beforehand. Line up the trim before screwing in. Once you have installed the trim then caulk it along the siding and the jamb. Caulk your screws as well so that they can be painted.
