Window condensation can become a problem when temperatures outside drop — and it doesn't only affect older homes with single glazing. Water collecting on your frames can be unsightly but it can also cause damage over time.

Condensation can happen anywhere in a property but is often noticed on window glass with a "steamed up" appearance. It is most often caused by poor levels of household insulation as well as inadequate ventilation. Thankfully, for those looking to find out how to solve condensation, there are simple steps you can take to ensure  window condensation doesn't become a longer-term problem for you.
