Repair exterior door flashing

Jeremiah Breer | Posted in General Questions on

Hi All,

This door needs a little TLC. It’s most recent issue is that my dog ripped the flashing trying to get at a rodent or something. Is there a way to fix this without taking the door off? My plan is to unscrew the threshold, take the old flashing out, slide a new piece of slashing under the door, replace threshold, and re-calk everything. I was hoping you all could tell me if I’ve skipped a step, or if this is a bad idea. 

Best regards,
Jeremiah

    I don't have any input for you, but I will give your post a bump in hopes that one of GBA's professionals can comment.

    Hi Jeremiah.

    I was able to retrofit decent flashing under a door by removing the threshold. I was actually doing the work because the threshold was wood (as was the door, door frame, and trim, in my situation) and it was in bad shape. When I got the threshold out, I saw that there was no flashing around the door at all. I decided to remove the casing and the trim board beneath the door, used a flush cut saw and took just a blade's width off the bottom of the door frame legs and was able to slip flashing beneath. I used some peel-and-stick flashing and some bent coil stock and felt pretty good about the protection it offered. All that to say, if you can remove the threshold, I bet you can retrofit some decent flashing there.

    I just remembered that FHB has this video series, Jeremiah. If you're not familiar with this work, you may find the second video in the series helpful: How to Replace and Old Entry Door
