Water leak patch on ceiling below en-suite bathroom

Big problem with water is it has a habit of traveling to the lowest point. You may have a stain in one place but 9 times out of 10 it has come from nowhere near the final point of rest. Only real way is to lift up floorboards in your en suite, or cut out sections of the celing below. If you have household insurance it may be worth talking to your insurance company, dependant upon excess ETC

 

I had a stain once like that, it was the bath trap which got clogged with hairs.

Does the water after showering drain quickly away or does it take time to disperse?

 

do not put more silicone over existing! Mechanically remove all existing silicone with a sharp blabe. put weight into tray and make sure there is not movement. if there is you need to cure that 1st. if all is good reseal with a good quality silicon sealant, jobs a goodun.

 

I t may not be leaking from the silicone joint. it could be that the shower door seals are worn and require replacing, they only seem to last a couple of years. Only noticeable when someone is showering with the doors shut.

 

New silicone won't stick to old silicone as well as clean surfaces. You need a bigger bead, and need to sqeeze plenty into the gaps(not just make a small cover).

Mr. HandyAndy - Really

 

Cut out old silicon.....clean off as much as possible. You can get a liquid silicon remover that helps....or meths.

Re-silicon with a good quality "sanitary grade" silicon.

You could after, fit one of these.....not a fan myself, but they do the job.

Also worth checking that all grout is intact with no loose areas and small bits that have fallen out
Water can get behind the tiles and run down the wall in this case

As above, cut out silicon (plenty of similar threads about this subject) but basically use sharp craft knife held tight against tiles, then shower tray. This will remove most of silicone. Silicone remover is good to remove any remaining bits, you really want the surfaces to be clean before you start again

Good quality sili is a must, try this one, great price at the moment too

I'm just a dyer but I've commented on this subject previously and always recommend buying a sealant tool kit. Usually get shot down in flames and get told "just lick your finger and use that, that's we do" but, if you want a really neat job, carried out clean and tidy, then you cant beat these kits. Seems like a lot of money for 3 bits of plastic but once used, you will realise that its money well spent

I've got the Fugen Boy kit (SF used to sell this and I guess pretty much the same) Dipped into warm water with a squeeze of fairy in it, shake off excess and away you go. Makes using silicone a pleasure not a chore

 

Most experienced bathroom installers know to fill a bath completely with water before siliconing the edges. This helps put the silicone under compression when the bath is empty and reduces the tension on the silicone when weight is in the bath. The same principle applies to shower trays which can deform or move downloads very slightly with the floor when you stand in them and eventually cause the silicone to detach. The problem is that few people have the patience to stand in a shower tray for the time it takes silicone to cure!
Shower trays are a frequent source of hidden leaks, particularly between floors in flats.

 

You wont want to hear this but after you have tried a repair without renoving the tray which has failed your only guarenteed solution for a successful repair is to remove the screen and tray, clean it all up, make good the wall and refit the whole lot.
Sorry but its the only guareneed way its going to get fixed.

 

Got to say that this is the best way to do this, isn't really a major job.

 

Regarding applying silicone, there used to be instructions on the tubes to clean surfaces with meths prior to using the silicone. I have always done this and never had a failure/leak (admittedly only on a small DIY scale with 2 properties).

İ also have a few patches come through on my living room celeing above is an ensuite. I realy do not know how it's happening. What I need is someone to come and diagnose the problem and fix it etc etc. Also to re-paint the ceiling downstairs. I phoned a few plumbers and they ask me to find where it may be coming from. I say most probably the ensuite. I just want someone reliable to come and help sort it all out. Can anyone help
