Streaming Wet Windows

Steamed-up windows and puddles on the window sill, damp patches, peeling wallpaper, black spotty mildew, water running down walls?

Have you tried all the basic fixes and the condensation is still streaming down the windows?


Why Does Condensation Occur?

Condensation starts when warm air collides with cold surfaces. Condensation also occurs when there is too much humidity in your home. Condensation is more of a problem in the winter months. Over 8 million homes suffer from condensation problems in the UK.

Condensation occurs with everyday activities like cooking, showering, drying clothes and even breathing. These activities release moisture into your home. The average family creates 112 pints of water per week. In modern air tight homes this moisture can’t escape.

When this moisture packed air comes into contact with a colder surface like a window or an exterior wall, it cools down rapidly and turns into condensation.

How to Fix Condensation

Put simply ventilation is the cure. Once you introduce good ventilation into your property, condensation will disappear within days. In most cases it’s not good enough to open a window the average property needs a lot more ventilation to clear the problem.

Once you introduce high performance extract fans in the bathroom and kitchen area you will notice excellent results. Most extract fans on the market today are not fit for purpose. Building regulation requires a bathroom fan to extract at 15 litres of air per second. Most extract fans fail to exceed  3 litres of air per second. This is also the case in new build properties. Kitchen extraction fans should perform at 60 litres of air per second. Most cooker hoods are not fit for purpose and only extract smells from food.

If a property is suffering from condensation on windows and mould spores growing on walls, ceilings and cupboards then the property would benefit from a whole house ventilation unit. The unit is installed in a central location and constantly quietly ventilates filtered tempered air into the property. These units are very efficient and have minimal impact on a home owners energy bills. Once a whole house ventilation unit is installed, condensation problems will be a thing of the past. Whole house ventilation systems will also eradicate mould spores. Over a period of 4 weeks mould will change colour it will die and the home owner wipes the infested area off for the very last time and mould will not re-appear.
