Preventing damp and mould

Here's some great tips that we’ve found work really well.

Working together we can help sort out the damp and mould in your home.

We’ll start by helping you understand what causes damp and mould. Knowing this can help you get rid of it and stop it coming back.

Penetrating moisture (rising damp)

What it looks like

it hardly ever has mould growth

it looks like a tide mark


What causes penetrating moisture

roof leaks

plumbing leaks

other water damage


Where it’s found

areas where a leak has happened

rising up the inside of walls


Report a repair


What causes condensation?

Condensation happens when warm moist air meets a cold surface, like a window or an outside wall. It mainly happens:

when we don’t open our windows often enough to let the warm moist air out

in colder weather

if a home is not heated properly

if the loft insulation is missing or in the wrong place

if there are very draughty windows

if the extractor fan is missing or not working

if there’s been water damage that hasn’t dried out


Where it’s found

above windows, on the ceiling or above skirting boards nearest the outside walls of your home

in places where there’s not a lot of air flow – behind furniture

the spores can spread to internal walls and furniture


Everyday things you do in your home add to the moisture in the air


Did you know?

1 person asleep for 8 hours           produces 0.3 litres of moisture
1 person active for 16 hours          produces 0.8 litres of moisture
Cooking                                           produces 3 litres of moisture
Bathing                                            produces 1 litre of moisture
Washing clothes                            produces 0.5 litres of moisture
Drying clothes                                produces 5 litres of moisture
Paraffin heater                                produces 1.7 litres of moisture


What can you do to help?


Increase air flow

  • avoid over filling your cupboards
  • leave space between the furniture and walls
  • open your windows to let the moisture out
  • if you have vents in your walls or windows, make sure they’re open.


Reduce moisture in the air

  • dry washing outdoors. If you dry it indoors, don’t hang it on the radiators, and remember to open the windows to let the moisture out
  • if you use a tumble dryer, remember this creates a lot of moist air. If it has one, make sure the ventilation pipe leads outside. If it’s a condensing tumble dryer, you still need to open a window to let the moisture out
  • use your extractor fans in the kitchen and bathroom
  • keep a lid on sauce pans to reduce heat (this'll save you money too as you can turn the heat down a little)
  • while in the bath or shower, keep the door closed to stop the moist air getting all round your home - when you finish, open the window for 10 minutes or so to let the moist air out
  • never use portable gas or paraffin heaters as they create a lot of moisture.


Heating your home

Don’t over or under heat your home. The temperature card will help you keep your home at the right temperature. Try not to heat your home very quickly, at a high temperature, as this will make condensation worse. It’s also very expensive.

Please contact us if you can’t get the temperature card to 18 degrees in each room when your heating is on.


Dealing with mould

Mould likes to grow on condensation. Here's some ways to stop it growing:

  • wipe down windows and window-sills when you see condensation
  • wipe down surfaces with bleach and water or a mould spray from your supermarket (always follow the manufacturers instructions)
  • when you’re decorating use an anti-mould paint in areas where you’ve had problems (area must be completely clear of mould)
  • don’t brush or hoover the mould as this can spread the amount of spores in the air


What to do next


Step 1

We need to try and build up a picture of the type of mould you've got and try and find the cause. Please fill out our questionnaire so we can find out if there’s a problem with your home that’s making the damp and mould worse. If there is, we’ll arrange to get it fixed.

If we can help you keep your home at the right temperature and with the right amount of moisture in the air, then we’re on our way to sorting out the problem.

We’ll send you an advice pack with a questionnaire to return with photos of the affected areas.

We’ll ask you to monitor this for 4 weeks. If you've still got a problem and have followed all of our advice, you can ask for a step 2 survey.

Report your damp and mould

Step 2

  • your maintenance manager will review the questionnaire and photos and will contact you to discuss next steps
  • we’ll offer you advice if we think there are some things you can do to help
  • if we think there are building problems we’ll arrange for them to be fixed
  • we’ll write to you to confirm what we're going to do 
  • continue to follow the 'What can you do to help?' advice from step 1
  • we’ll call you 4 weeks after any repair work has been done to see if this has solved the issue



Step 3

  • we’ll visit you at your home and do a full survey
  • we’ll let you know what we’ll do next
  • we’ll offer you advice if we think there are some things you can do to help
  • continue to follow the 'What can you do to help?' advice from step 1
  • we’ll call you 4 weeks after any repair work has been done to see if this has solved the issue



Step 4

  • we have a list of independent surveyors, who we'll ask to visit and check your home
  • we’ll review the survey results and call you to discuss the results
  • we’ll write to you and confirm what was found in the survey and what we’ll do next
  • if they find something that we didn’t find, we’ll put it right and apologise
