    Hi I've bought a new house and i have a upvc door fitted with a low threshold and every time it rains its leaking through the inside. Anyone knows what to do. Ive poured water on the door and it seem like its only leaking from underneath. I had a quick look at the rubber that slots in under the door and seems ok. Does anyone know where i can find this seal from also there doesn't appear to be any drain holes in the threshold im not sure if its meant to have it. Thanks.

    You would need to find out the make of the door to get that gasket.
    Is the external ground level flush with the threshold? It hard to tell from that angle photo

    How can i find out the make of the door? Yes the threshold is level with the ground. It seems like the water runs over the door weather bar strip and under the door somehow passing past the door seal underneath. Both the seal on the door and threshold look fine.

    Possibly
    Can you get the people who fitted it to come back, Is it still under guarantee?

    Drainage looks to be the issue

    Is that a pvc sill underneath the Ali threshold? If so looks like the gap between the Ali and the sill has been sealed. This is where the water drains.

    If it's not a pvc sill underneath, the Ali threshold might be base drain, again it's all been sealed up.

    Try to locate the drainage holes, if it's not draining, the threshold will fill up and seep inside

    The house was built around 1900.
    I cant see pvc sill under the ali threshold unless its buried into the ground.
    I think the ali threshold sits on top of the concrete ground. There isnt any drain holes on the ali strips, it should run off away from the house but somehow its passing the seal and get some water on the quarry tiles.
    Where the flipper type rubber is on the threshold theres small gaps on either side is this normal?
    No guarantee with the door as it was already in when i bought the house.

    I reckon the door is sat on a stub sill, you can see the cement line where it's been patched in.
    Can you pull that trim off at the bottom? Then get a pallet knife between the Ali threshold and sill, need to remove the silicone, you might then see some water come out

    I don't think it has a cill under it. I don't think there is any drainage built in either and I don't think that threshold was designed to have any.
    I think there are 2 main problems here although there could still be problems with the door too.

    1. external ground level is too high. Water is able to pool outside the threshold and if the wind is blowing towards the door it has nowhere else to go.
    2. I expect that there is no DPC behind that external floor/step moisture is probably soaking right through under the door like a sponge.

    To be honest you could try a dozen different thing here before you work out the cause/causes. But if it was my door one of the first thins I would do is cut out a section of that step tight to the door and fit something like this http://www.ebay.co.uk/itm/Drain-Cha...431188?hash=item5424aae054:g:z9IAAOSwRLZUAgh5

    Hi i dont think there isnt a sill under the threshold. The outside has been raised wheelchair ramp leading to the door. Ive poured water on the front with a plastic bottle and it starts leaking in the middle of the door. I think the water runs down the door onto the rain/ weather bar at the bottom of the door and drips off on the black bit of the threshold.
    I was thinking if i got a longer weather bar the water might drip off further past the threshold and onto the concrete ramp.
    Could that work? If not can i buy a new threshold if so where from as b&q and wickes dont sell them.
    Noticed my front door which is the same as the back door and its the same story there too.

    Threshold is part of the door frame and cant be replaced
