As autumn begins, UK households are being advised to place table salt on window sills to combat condensation, which can lead to damp and mould. The moisture problem arises when warm indoor air meets cold glass, causing droplets to form.
A 2024 report from the Ministry of Housing, Communities and Local Government found that around 23 percent of UK homes (6.5 million households) could be affected by damp and mould in the coming years. Minor condensation repairs for double glazed windows can cost between £300 and £500, according to MyJobQuote.
Experts from Lottomart suggest using table salt, a natural moisture absorber, to draw excess moisture from the air. Salt can be bought for as little as 65p at Morrisons or Aldi. The method involves filling a small bowl or jar with salt and placing it on the windowsill; when the salt clumps, it should be replaced.
Additional tips include opening windows daily for ventilation, moving furniture away from walls to improve airflow, and using extractor fans while cooking or showering to reduce indoor moisture.
