My new back door has water ingress through/under the door; we’ve noticed a damp patch on the screed on several occasions since installation. [The main builder cut a new hole for this door; the suppliers of the door installed the door].
Could this be due to a fault with the product/installation?
Or could be caused by the external paving level height? (I think this is about 20mm under the bottom of the sill).
If neither of these what would it likely to be?
Thanks.
