Damp and mould

Damp and mould

Condensation can lead to damp spots and mould developing in your home. This can make a property very damp and unhealthy to live in.

Here's our tips for keeping your house free of condensation, damp and mould

Condensation between windows (DGUs)

If you have condensation between your window, this needs to be reported to Mears via the repairs line. 

A visit will be made for the unit to be inspected, measured up and replaced. These are currently going through Mears via Clearview.

Preventing condensation

There is always some moisture in the air, even if you cannot see it. 

When moist air hits a cold surface it cannot hold it and tiny drops of water appear. You can see this when the mirror mists up when you have a bath. This is condensation...

  • Condensation occurs mainly during cold weather.
  • it appears on cold surfaces and in places where there is little movement of air.

Look for condensation or mould in:

  • room corners
  • on or near windows
  • in or behind wardrobes and cupboards, and 
  • in rarely used rooms

Condensation can lead to mould, which can contribute to asthma and other respiratory problems.

Reduce condensation - Produce less moisture

  • cover pans when cooking
  • dry washing outdoors, whenever possible, or over the bath with the door closed and the window open
  • vent any tumble dryers outside, or buy a self-condensing type. 

Did you know? Drying clothes in an un-vented tumble dryer produces a massive 10 pints of water!!


  • keep a small window ajar or trickle ventilator open
  • ventilate your kitchen and bathroom when in use, by opening windows or use a humidistat-controlled electric fan. These come on automatically when the air becomes humid, and are cheap to run
  • when having a bath or shower, keep doors closed to prevent moisture reaching other rooms, especially bedrooms. Did you know? Having a bath produces two pints of moisture!
  • ventilate cupboards and wardrobes, and where possible position wardrobes and furniture against internal walls.

Insulate and draught proof

Condensation occurs in cold spots. Insulating your loft, draught proofing windows and doors and installing cavity wall insulation will reduce cold spots.

Reducing cold spots will make your home cheaper to heat.

Heat more efficiently

Try to avoid cold areas in your home. It is better to heat your whole home to a lower temperature rather than heat one room to a high temperature. 

Condensation often affects the rooms that you're not heating, for example, a spare bedroom rather than where you are making the moisture. This is because they are colder.

Treating Mould

If you deal with the basic problem of condensation, then mould should not appear. 

To kill and remove mould, wipe down walls and window frames with a fungicidal wash. 

Follow the manufacturer's instructions precisely. Disturbing mould by brushing or vacuum cleaning can increase the risk of respiratory problems.

After treatment, redecorate using a good quality fungicidal paint to help prevent mould recurring. Note that this paint is not effective if it is overlaid with wallpaper.

Follow these steps to eliminate condensation and prevent mould.

Top Tips

  • to prevent condensation on mirrors or windows rub a cloth with a small spot of washing up liquid over the surface. Try this at home or in the car - taxi drivers have been doing this for years!
  • alternatively to prevent condensation on windows, cut a potato in half and rub across the surface then buff with a cloth.

Still having issues?

If you are a council tenant and have followed all of the above steps but are still having issues with damp or mould, get in touch:

  • Call the free phone repairs hotline on 0800 085 1313.
  • You can also send photos of the affected area to Damp.Mould@scambs.gov.uk 
  • The photos can then be assessed to determine whether a surveyor needs to come out to inspect the problem.
