I have just joined this forum to see whats going on with my walls inside my house....

I have black mold on every wall in my house i just want a heads up on how to tackle the problem. The house is about 100 years old ,stone walled cement render on the outside..

I'm no plasterer but i just wanted a bit of advice before i call a plasterer in
 
i think u need render systems to come and lime render your house.

mold is pretty bad for your respiratory system aswell
 
The S&c wont be helping to drunk to give you more thoughts at the mo but will comment again tomorrow when ime better.
 
He probably dont, depends what floor is down now, if its the original and a DPC is inserted, which is very difficult to do on a stone wall if that is what it is, the floor will need to be ripped up and a DPM put in.
 
Hi
mould is caused by water ingression by which ever means way or form.
water ingression to a property can be caused by simple human breathing we all inhale and exhale on average 5 liters per night of O2 therefore if you have a couple of people in one room without ventilation and you have a cold wall (solid brick or stone) then you will have problems.. just breathe on a window when cold and you will get WATER from your breath (condensation) if the condensation has no where to go... it stays in you room and or you whole property... you need to look at the structure of your home and find out where the problems are coming from?
is it a stone house without cavities?
is it a brick house without cavities?
is it a brick house with cavities?
is there ventilation in the property?
was the house built using lime or cement?
is there a concrete or timber floor?
let us all know and we will strive to give you an answer...
but be aware you either take it or leave it... so you answer my questions

1.. Stone wall without cavities
2.. The only ventilation is only from windows open 80% of the time inches opener's
3.. House was built using lime with the stone then it has been Cement rendered over at some stage
4.. Concrete Downstairs and timber upstairs

I hope this helps
 
A stone wall without cavities needs to be lime rendered so it can breath render systems is your man fitting air vents in every room and a 240v extractor fan in your bathroom will help also fit trickle vents to your windows
 
Also if you have a concrete floor with DPM any damp under the floor can be forced up the walls as it is douptful the stone wall has any DPC it will then be unable to escape properly because of the sand and cement render on the outside, some form of insulation may need to be considered.
