If you’re about to sell a property with a damp problem, tackling it should be a priority.  Not only does damp cause a terrible smell sure to put buyers off, it can also cause lasting damage and health issues for those living with it. Our guide to stop damp from spreading will help you tackle it head on.

Guide to stop damp from spreading

3 types of damp to be aware of

  1. Rising damp
  2. Condensation
  3. Penetrating damp

Tackling rising damp

Rising damp is caused by groundwater finding its way into a home through stone or brickwork and working its way from the ground up. Tackling rising damp can be costly and is bad health if not treated. A course of damp-proofing will help stop rising damp from spreading.

Dealing with penetrating damp

When water works gets into a house through the walls, the roof and floors, it can cause penetrating damp. Typical signs of penetrating damp are growing circles/blotches on walls and ceilings and wet and crumbly plaster. Potential weak spots on the property exterior such as poor pointing or damaged masonry can also be an indication of damp. The solution is to eliminate from the source. Check the sealant on exterior doors and windows, this may need stripping and replacing. Additionally keep an eye for any missing mortar or areas between bricks that may need re pointing.

Managing condensation

Condensation is one of the most common forms of damp and its harmful consequences are often overlooked. Condensation can be caused by drying wet clothes indoors, taking a shower and boiling a kettle to name but a few.  Bathrooms and kitchens are often most affected so proper ventilation here is essential. To keep condensation at bay, make sure extractor fans are working and all rooms have functioning vents.

Watch out for black mould

An excessive build-up of moisture causes black mould which is difficult to remove. This type of mould is not only unsightly, but attracts mites and, in extreme cases, causes respiratory problems. Mould and mildew eradication kits  and cleaning products that contain bleach will help tackle the problem.

Keep an eye out for ‘tide marks’

If your damp-proof course is defective, one of the first ways in which this will manifest itself is in ‘tide marks’ at the bottom of walls. You need to pinpoint the source of the problem, have the necessary building works done and use a dehumidifier to dry out the room affected.

Check your guttering

When guttering is damaged and rainwater is streaming down the side of the property, it will only be a matter of time before the water finds its way into your home. Checking your guttering for blockages and clearing them regularly will help prevent any damp issues from happening.

Dry your washing outdoors

Drying damp clothing on a clothes-horse in the spare bedroom can cause excess condensation and add to a damp problem. Dry clothes outside whenever possible, or hang them in a well-ventilated room.
