How to replace a rotted timber door sill?

[Adam78]

All, so far as I am aware, correct!

I would also advise the OP, not to drill down through the DPM, but to find some other way to fix. Drilling it will allow damp through..

How else can i fix it without drilling into the DPM?

Also how do I repair the section of DPM thats damaged in the pic? Are they jus strips layed on top of the bricks and how are they bonded down to the bricks?

Also whats the difference between DPM and DPC...

Not my area of expertise, but.....

I would be cleaning all of that area down to the top of DPM as best I could, sticking any loose DPM down with construction adhesive (CA), cutting a fresh piece of DPM and sticking that down with CA, so it overlaps the original as much as possible.

Finally fit a new piece of door sill (teak?), stuck down with CA and held down with heavy weights until it sets thoroughly. You might be able to add some sort of fancy escutcheon, at either end of the sill pressing it down = rather than drilling the ends of the sill to fix it. The sill needs to slope down from the door, so water runs away from the door. It also needs to be no wider than it has to be out from the door, to avoid people stepping on the unsupported edge.

As an alternative to a wood sill, you might be able to fit some tiles.

Wouldn't squeezing a bit of silicone mastic into the holes suffice and then pushing through the plugs...it only three holes?
