Finally finishing my garage now, but before I can do anything with the floor, I need to find some sort of seal for between the doors and the floor, as every time it is windy and rainy, water blows right under the doors as you can see in the pictures. The doors face into the prevailing wind, so leaves and rain blow under all the time.





The gap is around 20mm under the doors.

Is it just a case of buying one of these type of rubber seals (link below) and cutting bits out of it where the drop bolt and centre wood baton is, or is there a more elegant solution for barn style garage doors?

I have a similar gap on similar doors.... I've screwed in a very hard rubber strip along the bottom of the door with fairly large washers to spread the load.

It was more to keep mice out, but it keeps everything out.

There seems to be a big gap under the doors. How wide is it?

Does the strip sit directly under the doors and the height of it creates the seal?

Or does it sit under and behind, and butt up against the rear of the doors? (i.e do the doors close against it?)

It's a 20mm deep gap under the doors.

I presume the joiner who made me the doors left that gap in case I was tiling the floor or doing something that would consume 15mm or more of height. The casement of the doors runs all the way down to the floor.

It sits on the inside - on the bottom (obvs) and the width of it creates the seal. It barely touches the concrete base when closed, but it just touches it.

Does that make sense?

Nice doors. I guess the joiner left a large gap to prevent damp leaching up the doors and causing rot.
I have used a rubber seal that sticks to the floor and found it effective.

I just realised you mean it attaches to the doors, not the floor!

You don't happen to have a photo do you?

Could be, yes. Thats the reason I left a gap under the skirtings. I understand you need to keep anything wood or plasterboard off the floor in a garage in case of any water spills etc.

Rubber strip along the back of the doors so as not to ruin the aesthetics outside, or rubber tile inside to block the underside.

Yes, it attaches to the doors.... I can't supply a photo at the moment, the rugby is on, it's pissing with rain and the garage is a distance from the house. smile

I'll get a photo tomorrow as I need to move a car.

ETA attaching to the floor would have been a fiddle - plus, I'm not sure I'd want to drive over it.

Fitting a weather bar to the bottom of the doors would help, you could fit it hanging below the bottom of the door by 15-20mm

Then maybe a rubber strip screwed to the floor for the bar to close up against it.

Similar issue to OP.

I DiYed using the above to sort out a gap between our garage door and floor..... However looking the quality of OPs garage doors I doubt they would be happy with the outcome of my DIY approach!!!

I would also be concerned about vermin getting under that door.

I've used a rubber strip similar to what the OP suggests.

But where the concrete slab extends under the door gets very wet, so I sealed the surface of the concrete with some exterior floor paint.
Before I died this, I couldn't get the rubber to stick to the concrete for very long.


Why do so many garages face the prevailing wind?

A brush strip nailed to the door isn't going to keep water out. You need a rubber strip - as already suggested - stuck to the concrete with Sikaflex etc. Make sure it's high enough to span the 20mm gap.
