What is penetrating damp?

Penetrating damp is an all too common issue often due to a lack of property maintenance with the potential to seriously damage both the exterior and interior materials of a property.

What causes penetrating damp?

Penetrating damp generally occurs when water finds its way from the outside in and as such can occur at all levels of the building. This is unlike rising damp which occurs only at ground level. Penetrating damp can occur for several reasons as follows:

  • Ongoing and undetected leaks from pipes
  • Faulty rainwater goods ie blocked gutters, faulty down-pipes
  • Roof defects such as missing roof tiles
  • Damaged pointing, cladding, flashing or render
  • Long periods of rain and heavy winds
  • Walls exposed to wind driven rain
  • Flood water saturating masonry

What are the signs of penetrating damp?

As water continues to penetrate the property, the moisture will begin to soak through the bricks and mortar and into internal plaster and timbers.  This can lead to discolouration and damage of plaster as well as increasing the risk of rot and woodworm attack to timbers which thrive in damp conditions.

  • Growing circles of random damp patches on walls or ceilings
  • Wet and crumbly plaster
  • Drips and puddles
  • Green mildew, moss on outside walls
  • Signs of spores or mildew
  • Unpleasant damp smell
  • Blackened and rotten timbers.

How do ProTen treat penetrating damp?

When a penetrating problem is ongoing, damage can become become extensive as the damp conditions will lead to more serious damp related problems such dry rot, woodworm or timber decay.

We recommend the first step is to check for and fix any property defect issues to stop moisture from entering a property. This includes clearing blocked gutters, keeping roofs in a good state of repair, assessing for loose pointing, cracks in the brickwork and checking for leaks.  The moisture can then dry out which maybe enough to resolve the problem but sometimes the resuling problems that occur need a specialist treatment approach.

Where the problems are becoming a concern, ProTen Services will carry out a damp survey. This will allow us to assess the problem, identify the source of the penetrating damp, check for any resulting problems and recommend the necessary action.  The first steps will always be to stop the source of the water with the ongoing treatment dependant on the scale of the resulting damp problem.
