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.
