Leak under tiles, a job for a plumber?

darrenheaphy

We have underfloor heating and as you can see from the pic (see shadowy colour along the skirting) we appear to have a leak running underneath. Each day it gets slightly worse (have now switched off heating to that zone) as I've been marking it with pencil. I have no idea how to fix it - is this something I'd hire a plumber for? I presume we'd need to take up tiles and hopefully spot the culprit

Mind you, I've no clue if it is the underfloor heating. On other side of the wall is the bathroom but the tiles don't have the same shadow (but are also off a different colour so might stain as easily)!

Any advice really appreciated!

Yep, get a plumber. Its most likely something in the bathroom.

Have you a daily used shower on the other side of the wall?

Thanks for all the replies 🙌

On the other side is a shower, toilet and bath. The bath is used often (kids), the shower very rarely. There's nothing visible to indicate the leak is originating from here but, though the bath is a bit away, it has a fiddly hose attachment that leaks when we use it to rinse hair, for all I know it could be dripping underneath the bath itself when not in use, would have to be a lot of dripping to make it across the bathroom floor to the tiles.

That is a serious hight difference between the bathroom and the hall, water would easily pool for a long period under the bathroom floor before making its way out.

Once it finds a path out it will leak quickly.

The floor tile in your picture in hall appears to be saturated this would indicate a longterm leak.

If you're bath is used daily that is where I'd look first.

Get a plumber either way.

Do you have a shower tray ? Or is it a wet room. Yet rooms can give a lot of problems.

I would call out a plumber to start with.

Tell the plumber it’s not a call out though. Have a plumber in place to do the repair. No point paying €120 to tell you what you already know.

Might be worth checking with your house insurance too, it may be covered under that

Awesome, thanks again everyone, that's really helpful. Good call on house insurance too
