|Is the render porous in any way? Any rain landing on a wall in that
|situation (surrounded by trees and sheltered by a hill) is not going
|to dry off quickly, and will soak into the render given the chance.
I'm sure the render is fine. I drilled holes through it for
aerial cables a few weeks ago and it was like reinforced concrete
to drill through! Also, the drill-dust was very fine and very
dry. The exterior paint is in A1 condition on top of the render.
It all looks very new still (the house is only 35 years old).
|Something else to consider is that a wall has a high thermal mass so
|will remain cold for some time after the heating has switched on,
|especially if it is damp. Heating the house for short periods could
|make the problem worse as it will allow moisture removed from
|elsewhere in the house to condense on the walls before they have a
|chance to warm up.
Ahh. This could be a contributor then. I hate Central Heating at
the best of times and two hours a day is about all I can stand!
|A better way might be to continiously heat the rooms with sufficient
|background heat, leaving the doors partly open so the warm damp air
|can find it's way out of the room. Or, use a dehumidifier.
|Mould also tends to thrive where there is a lack of air movement, so
|moving furniture away from outside walls will help. Even a few tube
|heaters below problem areas will greatly help air circulation.
I will have a look at this as well, - in that case.
|I'd expect the same house in an open situation would not suffer damp
|problems, the developer probably used a standard design without
|tailoring it to the surroundings. Your roof looks like it has some
|moss on the top which indicates how damp the surrounding environment
True. In the winter this is obviously the case. Although, this
_is_ a south-facing house in 'sunny' Devon, and I'm told by the
neighbours that it's almost unbearable in Summer unless the front
blinds are closed! I'm expecting to make good use of the terrace
(shown on the picture mentioned earlier), throughout the spring,
summer AND autumn!
|Looks like cavity wall insulation could be the way to go, it will make
|the rooms easier and cheaper to heat too, but it might be worth
|consulting an expert on damp to get their opinion.
|Anyway sorry for rambling on, hope this helps in some way,
Certainly does! Thanks very much for your contribution.
