Hi all, hope you can give me some advice.
I live in a house which has been converted into two flats, basically upstairs and downstairs. Before we moved in the landlord gutted the whole flat spending thousands sorting it out. There were damp issues etc. We have had no problems up until now, about 10 months in. We seem to be getting condensation on one small wall in the extension at the back. Everywhere else is fine.
A full damp proof course was installed by a registered company. They have been out and confirmed that the dpc is working fine and that it is a condensation problem.
I have tried dehumidifier which helps but is obviously not a long term solution. The whole house has brand new double glazing with trickle vents (which are open at all times for ventilation). There is an extractor fan in the bathroom and we are having no problems in there.
There is a cooker extractor in the kitchen and we open the window when we are cooking which erradicates most of the steam but obviously not all. The kitchen is located next to the extension and there is no door in between.
We have central heating which is on most of the time apart from during the day if we are at work and during the night. We have no thermostat though, would it be an idea to have one fitted and leave the CH on low in the day? There is adequate ventilation via trickle vents and window locks etc. But we seem to still be having this problem with the one wall in the extension. I am worried that it will gradually start to move its way round the extension if it is not sorted.
Our landlord is on holiday at the moment but is coming on the 9th Jan (he is a quantity surveyor in London so I am hoping that he will understand the problem and resolve it asap).
Any advice/recommendations will be greatly appreciated.
