Water ingress under new (professionally fitted) garage door

Understandable, but if you had someone in painting and decorating, you would not really expect them to do some replastering as a part of the job. You contracted with them to fit the door, they did that. Did you have the same ingress with the previous door?

That is insulting!

Sorry if you feel insulted Harry, but quite honestly your analogies are quite patronising and quite frankly insulting to my intelligence. Your opinion is very welcome, but suggesting this is equivalent to carpeting a shower floor is not.

Clearly the company knew this could be a problem, they even sell a solution to fix the problem, just it was never offered to me nor flagged as a potential issue or something for me to consider. It would be well within the realms of their capability to stick a rubber weather strip down while they were here...and even have built it into the price (quite possibly).

The rubber seal is designed to keep out dust, leaves etc and help the door shed water. It’s not designed to stop water coming into the garage. If it did, then any pooled water it was keeping out would just run into the garage when you opened the door.

In my opinion, the door supplier should have quoted for and supplied a raised threshold to stop runoff running under the door. You would have paid more for it, but they’d have fitted it at the same time as the door so wouldn’t have cost any more in labour. I’d be going back to the door company and offering to pay for the threshold if they come back and fit it for free.

Yeah the latter point is what I'm think... would have just rather had it sorted in one go.

That is insulting!

I didn't start it with the analogies, but they were all comparable situations. A garage door installer's job finishes once the door is installed, tested and is in working order. I fitted my own door, then much later I addressed the ingress which it suffered under the seal. The rubber seal is simply there to allow for discrepancies in the floor level, only to keep drafts out. You were expecting far too much in expecting it to keep any surface water out - again, that is not its pupose.

Having said that - you claim your original up and over door did not have that problem. Up and over doors do not normally have a rubber seal along the bottom edge and only deflectors down the side rather than seals, so I am mystified as to why a much better sealing door might leak, whereas its very leaky predecessor did not.

It makes no sense, unless the new door is leaking wind driven rain between the horizontal sections, then down to the floor. The sections will have a sorted of round tongue and groove joint, so ensure water cannot penetrate through between them. Are those sections fully closing up, before the door comes to a stop fully closed?

If you do still feel the door installer ought to be responsible for fixing the ingress issue, then try taking it further with them. I doubt they will have any legal liability, but they might fix it as a good will gesture.

There's no water coming through the door itself, only under the rubber seal. I think the concrete floor is pretty flat an level, as the water is coming along the whole length of the door.

Exactly!

Well, possibly. The door installers specialise in fitting just these doors, likely fitting one or two per day, so they no doubt will have come across the ingress under the door many times before. I'm sure if they felt the extra seal was a regular business opportunity, they would offer them as part of their selling routine. As I suggested I doubt many of their customers will be all that bothered about a little ingress into a garage, which will get a wet floor regularly every time it rains and the car is parked. A wet floor is almost impossible to avoid in normal use.

To be clear it's the same company that has surveyed, manufactured and fitted the door. They also do sell the seals - please refer to their reply!

Andy live and learn! if you didn't want water in your garage you should have trowelled the slab accordingly before it set.

Yeah definitely mate. Getting the concrete floor levelled on the day of the pour was bad enough, never even gave this a thought at the time!

Problem is for this company is that for the sake of a weather strip, which I can buy for £75 (as the door is 4.8m) and I bet they could buy for a lot less wholesale... is the erosion of goodwill.

A neighbour wants a new garage door, will I recommend this company now...absolutely not. Their trust pilot and google reviews will be honest with these pictures, and may cost them more sales. Any little problems/niggles with the door, they're going to be back out under the warranty...even if it's something I could probably sort myself.

They will live and learn too :)

My new build has the same issue, but also gaps under it slightly. They refuse to fix it. I think the door doesn't have enough travel to appropriately seal.

As already said, the rubber seal is not designed to stop water passing under it. If there is a visible gap between concrete and rubber, then that can easily be adjusted by tweaking the limits.

I tried to tweak the limits but it hits the automatically torque retraction before closing the gap.
 
Is the torque setting not adjustable?

Closing torque is but the automatic retraction is a safety feature and has no controls.

As far as I can see it runs out of travel before being able to be closed at the very edges.

Would love any advise it's a real pain.
 
You mean the concrete is not flat, it is higher in the middle than the sides?

The concrete is flat, which is what has stumped me. The middle section of the door seals fine, it's the very sides of the bottom edge that do not.

I can adjust it so one corner also seals, but trying to get the other corner done results in the retraction kicking in no matter what I do!

How about the stick down rubber seal mentioned above?

Your floor looks much better than mine but it clearly is not level. The water is running in via a dip in the middle. It is pooling because the floor runs down at the point where it pools.

I completely understand that you are annoyed that no one offered you the option but would you have rather than they charged you another £300 for the threshold given that you can sort it out yourself for much less?

To be fair, I don't see how they could have known beforehand that the water would leak under the seal- unless they fitted the door and used a hose pipe to test it.

Having read your previous posts I am surprised that you really imagined that the rubber at the bottom would compress enough to make the seal completely watertight. The pressure required would be so great that you wouldn't be able to close the door manually.
 
Unfortunately there’s such a conflict of information here that it’s really got me in two minds - all this talk that it can’t be foreseen would make me think that it can be normal that a garage door should stop rain water…but then on the flip side folks say you shouldn’t expect it to be water tight.

If you look at the first photo, the water comes in pretty much along the whole length of the door, only once there’s a certain amount of water inside does it then run to the puddle.

I honestly don’t see why a rubber seal shouldn’t form a seal that prevents the water from coming in…but design rubber is flexible and should fit the contours of any small (and gradual) imperfections.

Im not expecting the door to water proof with 2 foot of water on the outside of it in a flood, but keeping the water out when there’s a rain shower I was…which seems to be too much for some folks.

The concrete would need to be very smooth and a lot of pressure be applied to the rubber seal. Neither condition of which is met by such a door.
 
According to building regulations, a garage is a non habitable room, therefore the requirement for damp proofing is that the ingress should not damage the building itself.
Of course in reality the floor is supposed to have the correct slope and threshold, and no one expects a puddle, but the same standards would apply as to a drive in terms of water runoff.
I think the suggested workaround on this thread are sensible and pragmatic and I'd certainly negotiate with the installer, but i think you'd struggle of you want to work out who is objectively correct in this situation, as both you and the installer are right in your own ways.
Good luck with it though and i hope you solve it.
