Damp, mould and condensation

Damp, condensation and mould

No one wants to live in a damp home. Damp and condensation can cause mould on walls and furniture and also cause serious respiratory health problems.

Penetrating damp

 

Penetrating damp is caused by moisture coming into the house through leaking or cracked pipework, a damaged roof, blocked guttering, gaps around window frames and cracked or defective rendering and brickwork. All of these problems can be remedied.

One of the most common causes of penetrating damp these days is poorly installed retro-fitted cavity wall insulation. The Big 6 Energy Companies (eg British Gas) have been offering free cavity wall insulation over the last few years and unfortunately this has led to a large number of properties being insulated with cavity wall insulation where either the property was unsuitable (eg cracked render), or an unsuitable insulation material was utilised (eg mineral wool).

Specialist Surveying Services can carry out a survey of your property to establish the cause of the damp problem and solutions to rectify the problem. These may range from low cost options, such as clearing a blocked gutter to more expensive options such as removing cavity wall insulation or re-rendering the walls. Please contact us on 029 2115 4753 to arrange a survey.

 

Rising damp

 

Rising damp is very rare and is due to a defective (or non-existent) damp course. This will leave a ‘tide mark’ about a meter above the floor. A number of options are available to prevent rising damp, including injecting a chemical damp proof course in your property.

 

Condensation Damp

 

Condensation occurs when moist air comes into contact with a colder surface like a wall, window, mirror etc. The air can’t hold the moisture and tiny drops of water appear. It also occurs in places the air is still, like the corners of rooms, behind furniture or inside wardrobes.

Condensation mould is unsightly and can cause health problems

How to reduce condensation at home:

 

  • Produce less moisture – simple things make a huge difference, like keeping the lids on pans when cooking, drying clothes outdoors (and especially not on radiators), venting your tumble dryer to the outside and avoiding using paraffin heaters or flue-less bottled gas heaters which produce a lot of moisture.
  • Let the moist air out and the fresh air in – Extractor fans are an effective way to get rid of moist air and steam so that less condensation forms.
  • Insulate and draught-proof your home – Warm homes suffer less from condensation, so you should make sure your house is well insulated. This means insulating your loft to the recommended depth of 270mm (about 11 inches), and insulating your walls with external or cavity wall insulation (where appropriate).

If you have damp or mould problems in your home, the first thing to do is find the cause. Damp and mould can affect your health, so it’s important to get rid of it. Please contact us on 029 2115 4753 if you would like us to carry out a survey of your property.

 

Health Problems associated with damp and mould

 

If you have damp and mould problems in your home, you’re more likely to have respiratory problems, respiratory infections, allergies or asthma. Damp and mould can also affect the immune system.

 

How does it affect your health?

 

Moulds produce allergens (substances that can cause an allergic reaction), irritants and, sometimes, toxic substances. Inhaling or touching mould spores may cause an allergic reaction, such as sneezing, a runny nose, red eyes and skin rash. Moulds can also cause asthma attacks.

 

Who’s affected?

 

Some people are more sensitive than others, including:

  • babies and children
  • elderly people
  • those with existing skin problems, such as eczema
  • those with existing respiratory problems, such as allergies and asthma
  • those with a weakened immune system

Due to the serious nature of the health problems associated with damp and mould it is important to rectify the problem as soon as possible, as the longer the problem is left, the worse the problem will become. All damp and condensation issues can be rectified so please call us today on 029 2115 4753 if you would like to arrange a survey of your property.
