Rising Damp Richmond

Rising damp is the process of water rising vertically up from the ground and travelling by capillary action through porous material such as bricks and mortar. This will cause the wall to become damp as hydroscopic salts travel into the brickwork and plaster. As water evaporates, these salts are deposited into the wall attracting more moisture from the atmosphere. image shows a property afflicated with rising damp in darlingtonAs the process continues the wall and surrounding area becomes more saturated and signs of rising damp will become evident such as crumbling of plaster and white tide marks appearing on a wall up to a height of around 1 metre. Problems such as dry rot, wet rot and wood boring beetle infestations are also more likely to occur as surrounding timbers become saturated. It is a slow process and can be present for many years before any sign of a problem appears. Rising damp will typically occur due to:

  • No damp proof course (DPC) as is commonly the case with older buildings
  • Deterioration and failure of the DPC over time
  • Changes in external ground levels meaning the DPC becomes bridged. For example if a new patio has been laid
  • Moisture travelling in between the wall and the render so bypassing the DPC.

Penetrating Damp Richmond

Penetrating damp is an all too common issue with the potential to seriously damage both the exterior and interior materials of a property. It is generally classified as water that finds its way from the outside in and it can occur at all levels of the building. This is unlike rising damp which occurs only at ground level.

Why does penetrating damp occur?

Penetrating damp can occur for a number of reasons as follows:

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

Condensation Richmond

Condensation is caused by an imbalance of airflow, heating and ventilation resulting in a rise in relative humidity within the atmosphere of a property.

As warm air, which holds more water vapour than cold air, hits a cold surface such as a wall or window the air cools and is unable to retain all the moisture. The moisture it cannot hold is released and deposited in the form of tiny water droplets onto the cold surface.

Where does condensation appear?

Condensation can appear at any height, on almost any cold surface and where there is little movement of air most commonly windows, north facing walls, corners and behind furniture. This distinguishes it from rising damp, which almost never occurs at heights of more than 1.2 metres over external ground level and which is confined to walls that are in contact with the ground.  Unlike condensation, rising damp normally results in the brickwork or masonry, being of higher moisture content, than the plaster/render.
