Dry-lined House Ventilation

    Hi,
    I own a 1950's 4 bed semi built of 9 inch block on the flat. There was no insulation at all so when I did a major renovation 5 or 6 years ago I got the whole house dry-lined. I also replaced the existing fireplace and installed a high output inset stove in the sitting room. The windows and doors were also replaced with upvc.
    The house is very warm but I have a few issues. I don't have any vents in the house and I'm wondering if I need to retro fit some.
    I also have some condensation in two upstairs bedrooms and a bathroom. These appear to be insulation issues as they are in the extreme corners of the room where the insulation may be thinner.
    Should I just fit standard vents or should I look at a ventilation system like a Drimaster 2000?

    Step one with a big bullet is to put a vent in any room with a fire place/stove. Please don't light it again until you have one in place!

    Do you have extractor fans in your bathrooms? And above the cooker in the kitchen? And do you use them? These will remove shower and cooking related moisture from the building.

    Do you dry clothes on radiators or a clothes horse indoors? If so you should probably stop doing so as it adds a lot of moisture to the environment in the house.

    Do you open your windows regularly to "purge ventilate" the house? This is not essential in many modern houses but can do the world of good in many houses both new and old.

    Finally - you should have a vent in all habitable rooms but you may still get mould if any of the above is happening. There are better ventilation methods than a straight hole in the wall but few cheaper!
