Mould

Mould is a fungus that can grow on almost any surface. Mould spores produce allergens, irritants, and potentially toxic substances. When these are inhaled, this can impact your health, so it is important to prevent mould forming. We need to control the moisture levels in the home by reduction, ventilation, and heating, as well as ensuring other structural factors are not causing moisture within the home.  

It is important to treat mould as soon as possible by using a anti fungicidal spray (please follow the product guidance), do not brush away mould, as it will spread spores around instead use a vacuum cleaner. We appreciate you may want to take action yourself but please monitor the issue, if mould becomes persistent, more frequent or you are unable to treat it then contact us to arrange a visit to your home. If anyone in the home has underlying respiratory conditions, then please report it to us as soon as possible here https://www.stockporthomes.org/my-home/home-safety/condensation-damp-and-mould/#MouldForm 

Penetrating Damp

Penetrating Damp is caused by water that enters the home from outside often leaving a white salty residue mark on walls and ceilings. 

This is usually due to common issues such as: 

  • Leaking roof due to slipped, cracked or loose tiles  
  • Blocked guttering or damaged rainwater pipes  
  • Leaking plumbing  
  • Rotten windowsills  
  • Crumbling or cracking brickwork or chimney stacks 

 

 The signs are drips & puddles, blotchy or damp patches on walls/ceilings and wet crumbly plaster.

Rising Damp

Traditionally this form of damp enters the home from the ground but internal factors such as excessive use of water when mopping or spillages can be a factor. Signs of rising damp are rotting skirting boards, peeling wallpaper and stained plaster.

Condensation

There’s always moisture in the air in your home even if you can’t see it. When the moisture hits a cold surface like a window or a wall, it turns back to water creating condensation.  

Condensation can be caused by. 

  • Too much moisture in the home  
  • Not enough ventilation  
  • Cold surfaces  
  • Inadequate heating/temperature

Tips to reduce damp, mould and condensation in your home
  • Ventilate your home, use your window trickle vents and open the windows for ten minutes every day  
  • Dry washing outside if you can.  
  • Prevent steam moving around your home by closing bathroom and kitchen doors  
  • Use a dehumidifier if you can  
  • Wipe down any condensation on windows  
  • Use your extractor fans and don’t turn off ventilation units.  
  • Try and keep a consistent temperature  
  • Heat your home – even for 10 minutes in the morning to help reduce moisture  
  • When cooking food in saucepans cover them with a lid to prevent steam escaping  
  • Try not to put furniture in front of radiators or leave a small gap in between them. This will help heat to circulate in your home  
  • After bathing and cooking leave the extractor fan running for at least 20 minutes and close the door to allow the build-up of steam to escape  
  • Close all your curtains at night to help keep the heat in your home, but open them during the day to allow sunlight to naturally heat your home  
  • Don’t dry washing directly on radiators. This makes it harder to heat your home and creates excessive moisture.  
  • Place clothes on a drying rack in a room where a window can be opened and keep the door closed.
