Water seeping under the new garage door

I've had a new garge door fitted. It is a up and over door. At the bottom there is a 10mm gap and whenever it rains really heavily, quite a bit of water gets in. Is there anything I can put at the bottom of the garage door to stop so much water getting in.

This is not at all unusual. The 'toe' of the garage floor slab usually sits proud of the outer face of the garage door , hence water will hit it and trickle in.

I regard it as a minor nuisance, but i do regard the ingress of leaves more annoying. I have fitted a nylon brush to the bottom of my garage door but i understand you can fit a similar rubber weather seal also.

The brush will encounter less friction so is likely to stay fixed. A snug fitting rubber seal will need plenty of screws me thinks.

P.S. i used self drilling screws to fix the brush.

Where can I buy these Eskimo garage seals? They don't seem to sell them online

you could try ringing the number at the top of there web page and ask them.
