I found out what happened to my back door threshold
we had a lot of rain Saturday. I went out to get puppy and get her in before it got too bad. By the time the 2 of us got up the steps the wind was up and blew the storm door away from me and flat against the siding. I couldn't get it w/o going back down the steps so I just went on it and shut the door behind me.
When I turned around I could see the rain hitting the threshold area and coming right on in an inch or so. I got a towel and rolled it up against the bottom of the door.
But if over the yrs this place sat empty and the security door (which doesn't shut tight unless locked from the inside) blew open in our monsoons and rain would have hit there yr after yr. over and over. I 'spect someone then just ripped that threshold out by hand because it was rotted.
major SIGH here ... I'm gonna have to go out and buy something like this - with metal toward the outside (and the slight angle down). If that part sticks out over the end of the floor there I'll have to shore it up underneath with a piece of wood into the siding else it'll bend down/break off. I'm hope it doesn't rain again for enough time to allow that wood to dry out totally.
I have one of these already to put on the door. Anyone know if it goes on the inside or outside? It needs trimmed a bit so I'll have to get out my new tool w/cutter blade - and practice on something else first. And get a drill bit for metal. I really haven't wanted to go out lately but guess I'll have to. I wish I could just twitch my nose and be at the ENTER door of Lowe's... and then back home with another twitch of it.
