Apparently we should blast the heating and open windows to combat the mould....
I wanted to give some advice on this, as I see it quite a lot on here, and I think education and knowledge is key.
Most properties nowadays have double glazing windows, combination boilers, insulation and roofing repairs (due to previous government grants/schemes etc)...
Basically properties are air tight boxes with human and pet habitation.
Easy way to explain this is.... when you’re using your shower or bath... and your windows and doors are closed what happens?
Condensation is caused by water vapour or moisture in the air, inside the dwelling, naturally the vapour tries to escape, and naturally comes into contact with a colder surface of the room such as a window or wall... In doing this the drop in temperature causes water (condensation) to form on the surface.
This water may then soak into the wallpaper, paintwork, plasterwork and on fixed fittings
There is 2 things that a dwelling needs to “survive” which is heat (sun) and air (ventilation) now think of the brickwork outside a property and how the elements are brutal against the brickwork, the bricks get wet, and the sun dries the brickwork.... Most external buildings don’t have “mould and condensation” and the reason why is because the natural elements maintain the exposure of water vapour.
Now apply that logic to inside a property, then add how many people are living in the property, pets, cooking, bathing, and everything in between... and you don’t heat or ventilate the property adequately.... what do you think happens?
Mould spores form... the mould spreads, and you then get the classic pin point black “spores”
Best way to avoid mould is be sensible and be proactive, when bathing, open window, during or after use for 20-15 mins, when cooking open window, in the wonder months, ventilate property for 10-15 mins each day... to save heat do one room at a time, or the most affected areas, use a mould clearer which has a inbuilt deterrent.
All of the above is just basics, it’s logical and it’s common sense.
Of course their is other migrating circumstances (repair faults) however most “damp” cases are down to the tenants living conditions.
