Water leak into footwell - dodgy seal info and DIY repair guide (Image links dead)

NotApplicable

Another place that I have _seen_ the water coming in from is the top of the door. Not the very top - but the 'curve' in the rubber seal above the wing mirror. To find the place is a bit hard to describe, but there is an indent in the door panel where it meets the dash. If I draw a line straight up from the point where the dash meets the door panel (furthest part of the shape from the front of the car), I can see that the rubber doesn't sit the same as the rest of the door.

I have seen water drip from this part straight down the inside of the door panel. I have seen it run down the metal work and go behind the door panel. In both cases, the water was on the black plastic just inside the door seal at the bottom. At times, it dripped straight onto the carpet.

My solution was to open the window, put my knee against the door panel and persuade the top of the door to lean in a little bit. Not really recommended, but so far, in all this torrential rain in the last week since I did it, I haven't had any more water in the footwell.

Finally got round to sorting the seals on my 1.6 this afternoon, all in all it took me nearly 5 hours from preparation to finish - longer than I expected lol. I spent a lot of time removing and scraping all of the old seal/sticky adhesive from the door carriers, and also gunk which has materialized from mixing with leaked water at the bottom of the doors.

The butyl tape was a bit of a pain in the arse too with how sticky it is and how much it canstretch, especially on a hot day like today (I wish I had placed it in the fridge overnight as mentioned on DubSteve's guide but I forgot :doh: ). The front doors I think were a success. The job for the fronts was near enough no trouble at all (apart from cleaning all of the old seal and the crap that it left on the carriers)

The rear doors, well... when I removed both door cards I was in for a surprise, it was obvious that one of the previous owners had tried/got someone else to try and sort them... and made a bit of a bodge with it. They had used a really tough black sealant that just did not seem to want to budge when trying to peel it off (this particular sealant had also deteriorated in the past as it was still leaking water at the bottom of the doors), this black horrible sealant though was just all over the place and felt like dry tar when trying to remove it off the door itself and also acted a bit like glue with how much it made the carrier stick to the door. I just managed to do the drivers rear side and using the butyl to seal it back up the best I can.

Finally got round to the last hurdle of the job, the rear passenger door. This one had also been bodged up with the horrible black sealant in the past but didn't look too bad, managed to remove all of the bolts holding the carrier in place... apart from one. The black sealant had got in the screw hole and was really holding the bolt in place, so much so... it sheared off when trying to undo it [:@] I couldn't even use my flat headed screw driver to break the seal between the carrier and the door because the black sealant acted like a glue. I decided in the end before I ended up doing some damage was just to use the butyl to seal the outer edge of the carrier carefully and hope for the best - just to add as well that I've noticed since owning my Leon that the rear passenger door never has leaked that much water compared to the other doors.

So, that was how I spent my Saturday afternoon and I really hope it pays off! We will see when it next rains.

Just for everyone's reference, here is the butyl sealant that I got off ebay:

A massive thank you to both andy tech & DubSteve for their guides, I really couldn't do without you guys. I owe you both a beer! :) - Liam

I've noticed on my Leon that since the seals have been leaking (who knows how long for, but longer than I've owned the car I bet) that both rear footwells are constantly wet/damp. Now that I've finally got round to do the seals, it's simply the case of waiting for the carpets to dry out - which I bet will take ages.

I'm amazed that despite the carpets being constantly wet, the car's windows have never built up condensation.

Get your seals sorted ASAP mate before they get any worse.

I used a lot of silicon and sandwiched it between the two panels then screwed them together. I thought it would last for a couple of years - will double check it every now and again. I went on Holiday for 2weeks prior to fitting it and came back to damp , milldew and a mushroom :(

I know nothin worse, that's the way I done it too you never no it might work. Nothing worse than opening your door and getting to find a load of water fall out.

After renewing the door seals i found i still had a leak passenger side which still gave the results of the door seal but actually turned out to be the access hole seals for the window glass clamps,

just a heads up, they look sealed but i took my door card off whilst it was raining today and saw the drops physically dripping from the rubber seals for the access holes,


silicone smothered on the seal & internal seal and all seems good!

Im getting water present on both my front door sills after raining, but no water in my footwells as far as I can tell. Is this likely to be the door seals at fault im guessing?

Yeah - I had it when you open the door just resting in pools - when I touched my foot well floor it wasnt wet. I only really noticed it when I went on holiday for 2 weeks and it must of tipped it down as the footwell carpet was completely sodden.

I removed my passenger front seat and removed the plastic trim and then I could lift the floor carpet and it was sodden. It only take a few hours to see if the floor is wet. The door is really easy - its just popping the plastic away from the door which is worrying but the antibacterial clear sealant I used from BBQ seems to be doing the trick.I loosened the screws and squirted it all in and screwed it back tight forming a great seal.

It well worth ago & the guide on here is really good.

Cheers
