Title: Condensation problem
Post by: Sadie20 on July 12, 2011, 08:34:26 am
I have just moved into a new build flat and I have a problem with condensation.
What would anyone recommend that I could do?
The house builder says it is normal and once the building has dried out the condensation will stop.
I am worried that this may lead to mould growth if my flat is damp.
I am at work all day so cannot leave the windows open.

Condensation can be a big problem in newly-built homes.
Timber frame homes are particulary susceptible as the polythene vapour barrier stops the home 'breathing'.

The only solution is to keep the home warm and improve ventilation.
This can be done by ensuring extrator fans are always used when cooking and bathing.
Opening windows on fine days.
Ensure the window trickle vents are always open.
Do not dry washing inside the home.

If not responded to, condensation will lead to mould growth and the spores are known to be a health hazard.
Most builders and the NHBC believe condensation is a "lifestyle hazard" and as such is not covered under their warranty.
However, it is not unknown for condensation ( to be caused by a hidden leaking pipe over a period of time which is covered by the new home warranty.

i agree with the last comment ..and would also say

it is a common problem with new homes , and requires the right balance of ventilation and heat ....just like in your car when the windows steam up

its all about getting the relative humidity right keep the trickle vents open and introduce heat to a new home gradually

we find that winter plastered houses are worst affected

solution ....if not too badly affected a simple anti bactericidal spray will clear the black mold spores ( mildew )

if very badly affected and re-occurring the plaster board may have to be hacked back and replaced....( worst case scenario )

A solution of diluted bleach (10% Bleach : 90% water) will also kill any mould spores.
Just apply and leave to dry then wash off the following day.
Be careful not to get beach on your carpets!

People dont realise that the only way to reduce condensation is ventilation and heating.
As the two solutions are at odds with rational thinking "I dont want to let all my heat out"
the water vapour stays in the home.

New home owners should try and buy a home that has been built in the spring/summer.
