Patio door threshold

TheCyclingProgrammer

I'm currently trying to establish what work needs doing to fix some of the issues in our homebuyers report on a house we are buying.

One issue raised, and that we'd noticed, was that the patio door threshold was in a poor state of repair (the vendors had removed the carpet recently). The door no longer leads outside as there is a conservatory extension.

Here's a photo:

The house is currently being investigated for damp after the survey found it around the perimeter and looks like it might be responsible for this damage (I might be wrong but there seems to be some dampness in the bricks).

Assuming the damp issue is solved, how do we rectify this? The plan was to put down laminate wood flooring and I'm hopeful we can take it right up to the patio doors levelled using suitable underlay then place a piece of trim/scotia along the bottom to tidy up the join over the expansion gap.

I'd prefer to DIY this if possible. Should I just be chipping off all the remaining loose mortar (?), cleaning it up and laying a new bed of thin mortar, then possibly run some sealant between the floor and bottom of the patio doors to finish the job? Or should I be doing something else entirely? Thanks!

Your best bet would be to fit a piece of timber across the width ie a tread board usually a window board is used this would go on top of the laminate and helps with ware around the door opening .

Thanks, that doesn't sound like a bad idea. So take the laminate up to the wooden beading at the threshold then cut the window board to fit on top? Flush with opening or slightly wider as you would a window?
