THAT leak

The only way to go. I isolated a leaking window problem to the water getting in through one of those confounded brush seals into the frame. Now waiting for the fitters/manufacturers to cure their error.

 

How is the window upstand waterproofed on the outside? I presume there is some flashing. Is that cracked? Does it need replacing/repairing?

Leak is coming in on slab not through upstand . Above slab is insulation then waterproof roof. 100% certain roof doesn’t leak .

So as it’s now stopped raining decided to move crap out the way outside and look for anything obvious . Did find this gap behind the gate post . You can see the water proof roof ends at the post .

Need the leak to dry out and then I’ll tip a water can of water in that gap ….

[Pocster]

Ordered a cheap iPhone endoscope ( yes @Onoff broke the old one from over use ) . Be interesting too see exactly where this gap leads anyway .

I vaguely recall this gate post was very tight to the build I.e I had to dig out some of the external insulation to the below ground section to get it in …

Another ‘ possibility’ 🫤

So I decided to trawl back through years of photos looking for that wall edge construction .

i remember now there was an issue where the stone wall on the inside at this point would sit on the external insulation .

So the SE designed a metal bracket to hold the stone but I had to put special I.e expensive thermal bricks ontop .As this part is different just wondering if the issue is there …

Water round the gate post to start with. We await with baited breath

lol !

it hasn’t rained since early morning . 
So I could see it leaking through this morning as expected .

Waited until about an hour ago . Though not dry in the upstand the drips were less . So I tipped some water behind the post ….

It’s dripping now . But that’s not a conclusive test of course !

I really need some sun and zero rain and then the inner upstand is bone dry .

Test again then …

Weather this week looks pants - so will have to wait .

Water, probably dog's wee.

I am passing Bristol in Friday, more than happy to add to the liquid reservoir.

More than happy as long as I don't have to pay the congestion charge that is.

... with leak disclosing dye in it?

Yeah ! Fab idea, lets all go round to @Pocster's and piss on his gatepost. @Pocster  provides the beer all night.....

Oh, we were meant to ask first?  Sorry...

I don't, and always manage to get it though his letter box.

Hasn’t rained for a day now .

So went out and tipped a watering can of water into that gap 30 mins ago .

Nothing on the inside …. Just want too see 1 drop - but nothing . I guess it might take time to soak through the blockwork , here’s hoping .

[Pocster]

Got my endoscope .

Been sticking it in every hole I can find .

No joy ( well joy , but not found the source of the leak )

Try sticking it where the sun don't shine.

Always works for me.

Seriously, you might want to invest in some leak detection dye.

Yeah I tried that before .

I put a load of red down the lane - none came through . My assumption was maybe it wasn’t enough constant water I.e rain .

I really just want to put water somewhere ( on a bone dry day ) and make it come through .

It never leaks under light rain only heavy .

My next suspect is this down pipe - but to run all that way ( past other walk on glazing unit ) and come out at the front one seems highly unlikely .

But I’ll stick a 90 on it ; a 3 metre pipe and direct the run off away from the corner .

Perhaps when it rains heavy it pisses down the pipe and splashes up ‘n under the roof …. I.e under the white render 

Running out of ‘possibilities’ … 🫤

Here’s the red I did down the lane years ago .

Looks like I murdered someone - but it isn’t a conclusive test anyway

Drizzling all day - no leak .

I’ve noticed this before - needs to be substantial rain to cause leak . Kind of suggests not the lane .

I did find this corner where roof flashing meets build . With the down gutter nearby perhaps it runs back over the roof with heavy rain …?

Time for the old gloved finger check?

[Pocster]

Been using for almost the 1st time the search facility . Can see this leak dates back to around 2018 - so should really find it and fix ….
