I have an exterior door that has carpet on one side and a step down to the deck on the other. The threshold began to bow because of a leaking gutter. Now I need to replace the threshold and I have removed the adjustable part of the old threshold but don't see any screws so have realized I will need to sawzall out the old threshold.

My question, looking at the photos do I need to cut the bottom of the door frames to slide the threshold in place? Before I do that I wanted to make sure I was going about this correctly. Or, can it be done by sliding it in from the carpet side?

Thanks,

Randal

The pictures came in 90 degrees counter clockwise. How do I stop that in the future?

Someone else will have to help with the pictures---The thresh hold---i can help there---

The thing is stapled or screwed in from the bottom---removing it requires that sawsall you mentioned---when you do go to replace it---add proper waterproofing under the new sill---

Truly good door installers have a metal pan made--
Others use a tar backed membrane called 'window wrap' to protect the subfloor and framing from water intrusion---

then bed the new thresh hold into silicone caulk---
I cut the thresh hold with a chop saw---this can be dangerous if done wrong---

I've had a scare doing just that job and have a damaged miter saw to show for my moment of inattention----

Thanks for getting back to me. I just want to clarify are you saying I will need to cut the door jambs for it to slide under? If so, I was just going to cut it by hand.

The threshold is 1 1/8" in the highest point. So is there a way to not have to cut that much and then angle it in? Or, do you have to have a straight shot of clearance to get it pushed back?

I'd bet that threshold was never flashed when it was installed and there was no support installed on the underside where it sticks out past the subflooring.
The best way is to remove the whole door, add the needed support, flash, install the threshold to the bottom of the jambs and reinstall the door.

You can cut the old threshold off at the side of the jambs--and leave the little bit of old threshold under the jambs---
