Door threshold problem - interior/exterior levels the same

[Rystar00]

Hi all,

Back again for some more of your sage advice!

Spotted water leaking under the back door threshold (in the middle of a full house refurb and spotting things as I go) and noticed that the interior floor and exterior step levels are the same. There is no threshold, sill or weatherbar other than that useless bit of chrome you can see in the attached pictures.

Now the thing is we are planning to lay slabs on the step which will raise it by a further 50mm or so.

What is the best way to fix this please? We are on a budget so we are looking to do a watertight job now and look at this again properly in the next couple of years or so. This door will never be used as we have bifold a in the extension. Should have bricked it and banged a window in before it was plastered!

Thanks very much in advance.

Ryan

i don't approve of laying slabs on top of an already too high outside level. For instance where is your DPC?
the way to go with the water seal is to cut of 1/2" from the bottom of the door, but only half the thickness of the door. Now you buy the correct ali extrusion which is like an inverted T, with the upstand only 3/8" high, often these have a built in rubber seal. Plug and screw it into the floor so the seal is against the step in the door bottom, or if it has no seal leave a gap of 3mm and use draft excluder foam on the door. So now the bottom of the door has a draft proof seal and a water seal. Now put a drip rail on the outside of the door to protect this seal against driving rain.
Still don't like the slab idea, leave a 2" gap at least 6" wider then the door with some sort of drain so rain water can drip away.
