The results show that 49 per cent of householders do not clear or clean their gutters and downpipes, which if left, could cause extensive water damage to bricks, rot windows and cause damp.
Worryingly, 68 per cent of households that already have damp do not dry out affected areas or use a dehumidifier. As well as damaging the property, damp areas encourage mould and can increase the risk of illness. The research also revealed that 42 per cent of homeowners do not service their boiler. Not only could this lead to a breakdown but it can also result in more expensive gas bills.
Martin Scott, head of Churchill home insurance, said: "It is easy to ignore your boiler and central heating in the summer months, but you should make sure they are in good working order. Don't wait until the weather turns cold before having the boiler serviced. Release the air from the radiators if necessary and clean out any grilles.
"Do a top-to-toe inspection from the floor to the roof space. Look for signs of leaks in your attic, making sure that timbers are free from damp and woodworm. Check that pipes and tanks are fully lagged. From a cost and environmental point of view, it's good to have at least four inches of loft insulation."
