Damp can be a serious issue, but did you know that there are different types of damp? The most common types are rising damp, penetrating damp and condensation, and knowing which one is affecting your Cobham property will help you eradicate the problem in the quickest and most cost-effective way. As a damp proof specialist, Downs Property Care Ltd has extensive knowledge of different types of damp and how best to treat them.

From commercial damp proofing to wall tie replacements, wall repairs and structural alterations, we undertake a range of expert services to maintain the condition, stability and safety of your property.

The following should give you a better idea of what type of damp is affecting your property, but for a professional diagnosis and inspection, along with tailored advice, don’t hesitate to call Downs Property Care Ltd.

Rising Damp

Rising damp is the result of ground water moving up through a wall or floor where the damp proof course or membrane, or both, has failed, or where suitable damp proofing measures are not in place. Rising damp can also occur from insufficient drainage or if the ground outside your Cobham property is higher than the damp proof course.

Our damp proof specialists can identify the cause of rising damp and undertake suitable domestic or commercial damp proofing to fix the issue, as well as structural alterations and repairs to fix any associated damage. This includes wall repairs, wall tie replacements, lateral restraints and plastering. Signs of rising damp include:

  • Damaged Skirting Boards or Plaster

  • Peeling Paint or Wallpaper

  • Tide Marks on Walls

  • A White Powder-Like Substance on the Affected Wall

Penetrating Damp

Penetrating damp happens when water leaks through walls and is generally caused by structural problems. Unlike rising damp, which travels up walls, penetrating damp moves horizontally and may expand across walls and/or ceilings.

Common structural issues that can cause penetrating damp are:

  • Cracks in the Walls

  • Internal Leaks

  • Faulty Guttering

  • Faulty Wall Ties

Luckily, Downs Property Care undertakes a range of structural alterations and renovations to fix these kinds of issues for customers in Cobham, Ash and surrounds, including wall repairs, repointing and wall tie replacements.

In rare cases, issues with cavity wall insulation can also cause damp, and to fix this we remove cavity wall insulation. We also offer domestic and commercial damp proofing where suitable, as either a remedial or preventative measure.

The most obvious signs of penetrating damp are damp patches on walls or ceilings, which may get darker when it rains.


Condensation is the most common cause of damp and is particularly a problem in kitchens and bathrooms. Condensation is mainly a winter problem and is often made worse by central heating which gets very warm then cools down again, or by lack of ventilation.

Signs to look out for in your Cobham property include water droplets on walls or windows and visible dark mould, particularly on glass or around windows. You may also notice an unpleasant mouldy smell. One way to reduce condensation is to improve insulation around your property, which our damp proof specialists can do with external wall insulation and loft insulation as well as cavity wall insulation.
