Hike in energy prices could mean an increase in damp and mould in homes

With energy prices on the rise, people are turning off their heating to save money. However, it could end up costing them more long term.

Derbyshire’s building control services provider, DBCP, is urging people to try and keep their heating on and not block ventilation in their homes, as they risk causing damp and mould problems which are damaging not only to the fabric of a building but also pose a health hazard.

Building Regulations require all new buildings and alterations to existing buildings to include damp proof courses where walls and floors are in contact with the earth. However, damp proof courses do not protect the building from internal moisture build up caused by condensation which can damage plaster and paint, as well as lead to window frame decay.

A family of four generates around 280 full buckets of moisture on average per year through everyday activities such as cooking, showering, drying clothes and even breathing. In new build homes, the problem is worse as up to 8,000 litres of water (about 800 full buckets) may be included in mixtures and materials and will take up to two years to evaporate.

If excess moisture cannot escape, then it can also become a health hazard. Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances.

According to the NHS website, inhaling or touching mould spores can cause an allergic reaction, such as sneezing, a runny nose, red eyes, a skin rash and even asthma attacks. Babies, elderly people and those with respiratory and skin problems or weakened immune system are among those affected the most.

David Pratt, Building Control Manager at DBCP explained: “To conserve heat as we try to manage our energy bills, people can be tempted to block all draughts, like covering an air vent, in an attempt to make their homes warm. However, it’s important to ensure that air is able to circulate in order to maintain a good moisture balance. If there isn’t a good moisture balance in then it will cause damp and mould problems in your home.”

To ensure you have a moisture-balanced home, David recommends five simple steps:

1. Open a window – when moisture generation is higher than usual, (e.g. when showering or cooking) increase ventilation by simply opening a window or turning on an ex-tractor fan.

2. Keep gutters clean – ensure there are no rainwater or plumbing leaks which could cause damp.

3. Dry laundry outside – drying laundry inside typically increases interior humidity by 30% on laundry day and 15% overall. Even in freezing temperatures, your clothes will dry eventually.

4. Take cooler showers – lowering the temperature of your shower by just a few degrees, won’t add as much steam to the air, which helps with humidity levels.

5. Heat your home – although energy prices are continuing to rise, avoiding damp and mould issues will save you more money long term.

David added “Dampness and mould in properties has always been an issue and it’s partly due to the cold climate we have here in the UK. Fortunately, there are many low cost and free solutions we can put in place to tackle the problem and ensure we all maintain a healthy, moisture-balanced home. However, if you are worried about moisture build-up, damp, mould or any other issue with your property, seek advice from a property maintenance of construction professional.”
