Damp - big problem ?

[FunPinkSwan]

Hi,
looking at this room (kitchen) leading on to a utility on the left and a storage room on the right behind the door, the estate agent has confirmed it’s mould that’s growing on door and wall (as seen black patches on picture bottom of door and wall), from my own research I believe it’s called rising damp , I could be wrong here .

I was wanting to take down that wall and door anyhow, but where could a leak be coming from if it is the case , I don’t want to just fix over it I want to find the source. Hoping a damp surveyor can help me with that but has any one had any experience with this and should I be majorly concerned?

many thanks

To what i know rising damp is coming from the ground, so you would need to damp proof the ground floor. Could have in injected or have plaster removed and special plaster up. I believe problem with rising damp is subsidence but not 100%sure. Could it just be where previous Tennant had something in front of that part of wall?

How would rising damp affect a door?

Hard to tell without lifting the floorboards.

Assuming the house has suspended wooden floors, and that is a brick wall then it will have brick footings. The slate DPC might have failed or it might be a load of debris in the void that is breaching the DPC.

Also check the outside of the house to make sure that the airbricks are all unobstructed and free flowing.

Or could be a leaky pipe.

Rising damp is rarely a real thing. And you will rarely get an independent view from a “damp specialist” as they are there to sell damp treatments, typically chemical injections which rarely if ever work.
That damp is on an internal wall and u said it’s also on the door. I would check humidity levels in the kitchen it may just be that. Clean off the mold get a dehumidifier and monitor the situation see if it comes back. Also it could be a leak. Are there any pipes running behind that bit of wall that could be leaking?

My inexpert guess based on the way it's across the door would be that something used to be in front of that area that was stopping the area breathing and it's condensation type mould. If it was damp coming up from below I'd expect the door to start rotting rather than having mould on it.

Is there another room on that level that has a water supply? If so, could be a leaking pipe or drain under the house in that area. If not, worth checking that everything drains directly outside, ie rather under the house. Other thought, is that side room original? If not, could have been built under a drain.

My DD and her BF have a damp bedroom in one corner, and looks like it is down to a cracked drain so worth investigating.

Definitely do get it surveyed and advice.

Thanks all - very useful
