Condensation ? Anyone had a positive pressure air flow unit fitted ?

[KatieDD]

It seems to be the answer as we have ventilation in the house at all and it's a funny laylout but they are £500 each and we need 3 so would love to hear if they've worked for other people ?
Thanks in advance.

haven't had it done, but considering it to solve our problems, as it was suggested on another thread about condensation (by someone who had had one fitted). thought you only needed one per house though. what company(ies) are you thinking of using?
