Underfloor leaking pipe

[Greenstar22]

I could get a funny smell from ds bedroom and I noticed the pressure on boiler kept dropping. DH eventually investigated and yes a joint was dripping under the floor. It's fixed but there's a huge amount of water I think it's been dripping for years.
It now smells obviously! Am I best to leave windows open or dehumidifier on?
@pigletjohn You're advice is amazing if you're around?
I know it takes weeks for concrete to dry out how long before he can sleep in there, I'm a bit worried?

Dehumidifier and a fan is the best option, or open windows second best. If you open the windows with a dehumidifier on you'll mostly dehumidify the outside air.

a concrete floor you say?

is it a ground floor?

you don't mean a wooden floor with concrete underneath?

was it a leaking radiator pipe?

what can you see of the damp patch?

lift any carpet or other floor covering (likely to be ruined anyway, but if just a small patch you can fold it back so air can get at the wet patch

@Daftasabroom yes I was thinking that if the windows are open and dehumidifier is on its a waste of time. I'll try the fan thanks 😊

OP can I ask what the smell was like? I suspect we have the same thing but I haven’t narrowed down where the leak is coming from if it is a leak. Ours can be smelt in the kitchen, the bathroom above and the bedroom next to the bathroom, basically following the course of the hot water pipe coming from the boiler.

@tealguitar it's like a musty kind of smell, my dh couldn't smell it (didn't want to smell it!!) I bought a moisture metre and ran it along where the pipes were and it was really high so was obviously something going on

Thankyou! Yes ours is kind of musty/ mothbally - my Dad said it smelt like all houses when he was a child...

I had someone come out with a moisture meter but they just kind of waved it at the outside walls a bit, they didn't follow the pipe (I hadn't thought then that that is what it could be)- I might get my own.

@TealGuitar I got one on amazon which reads wood and walls. Was only about £15. I just tried on the dry walls at the bottom and skirting boards then did it where I suspected the leak was and the alarm went off🙄

@Greenstar22

Hello, did you see my note 08.34?

@PigletJohn I only saw this now. Its on the ground floor underneath a wooden floor so the pipes are on the concrete. There is laminate flooring but this is pulled up. It was a joint where the leak was not on the radiator, was dripping quite alot. There was a huge puddle of water which seems to have decreased alot today after we mopped it up and dehumidifier but obviously still wet

is there a void between the wooden floor and the concrete? how deep? is it ventilated with airbricks?

does the laminate sit on floorboards on joists? is the floor chipboard or planks?

is the puddle still visible?

how old is the house?

tks
