Water leaking in under UPVC patio door frame.

[Andwarr]

Hope someone can help, please.

We've had a problem with overflowing guttering/downpipe, which is now repaired, but it has revealed a gap under our UPVC patio doors, as when the surplus water was pooling outside the doors, it was finding a way in between the render and the base of the door frame. There is no obvious gap, so I'm assuming the entry is through very small gaps where it isn't sealed fully.

Is there an appropriate sealant that I can apply both outside and inside along the join of the frame and concrete, or would you say I need to get a professional in to remove and re-set the whole door and frame unit?

Any advice would be greatly appreciated.

Thanks

I would think about installing a shingle drain against your wall, if water is pooling and getting under your doors the outside is too high. It will also allow you to get right under the cill to seal properly, something which the fitters would never have been able to.
