Clapham contains a large amount of older residential housing, including Victorian and Edwardian terraces, period houses, converted flats and other properties that have been altered over many decades.
The age and construction of these buildings can make moisture problems particularly complicated. A damp patch on an internal wall does not necessarily mean that the property needs a new damp proof course. Moisture can enter a building through the ground, external walls, defective rainwater goods, roofs, plumbing, high external ground levels or below-ground areas.
Our approach is therefore to identify the likely source of the moisture before recommending appropriate remedial work.
Many Clapham properties were constructed before modern cavity-wall construction became widespread. Older solid-wall buildings respond to moisture differently from modern homes and need an appropriate diagnosis before remedial work is specified.
Victorian terraces are a particularly important part of the Clapham housing stock. Older solid brick walls can be affected by moisture entering through defective pointing, external render, bridged DPCs, defective rainwater goods and changes to external ground levels.
Edwardian houses and conversions can experience moisture around ground-floor walls, bay windows, chimney breasts, external elevations and areas where previous alterations have changed the way the original building deals with moisture.
Some Clapham properties contain basements, cellars or lower-ground accommodation. These areas can experience water ingress, condensation or moisture from below-ground walls and floors and may require specialist waterproofing or tanking solutions.
Rising damp occurs when moisture from the ground moves upwards through porous masonry. It can be associated with a missing, failed or bridged damp proof course.
Typical signs can include dampness to lower sections of walls, salt contamination, damaged plaster and recurring decoration failure. However, these symptoms can also have other causes, which is why proper diagnosis is important.
Learn more about rising dampPenetrating damp occurs when moisture enters through the building fabric. Common sources can include defective gutters and downpipes, damaged pointing, cracked render, leaking roofs, defective flashing or damaged external masonry.
Treating the source of water entry is normally an essential part of resolving the problem.
A perfectly functioning DPC can be compromised when external ground levels, paving, render or other materials are raised above the original damp proof course.
This can allow moisture to bypass the intended moisture barrier and contribute to dampness internally.
High Ground Levels & Bridged DPCCondensation is different from rising damp. It occurs when warm, moist air meets colder surfaces and can result in mould growth, surface moisture and damaged finishes.
Ventilation, heating, insulation and the way rooms are used can all influence condensation.

There are several possible causes, including rising damp, penetrating damp, bridged DPCs, high external ground levels, defective gutters and downpipes, leaking plumbing, defective external masonry and condensation.
It can, but a new DPC should not automatically be recommended simply because a property has damp. The moisture source should first be investigated because penetrating damp, condensation, plumbing leaks and DPC bridging can produce similar symptoms.
Moisture and soluble salts within masonry can contribute to plaster deterioration. If the moisture source is not addressed, new decoration can fail again even after plaster has been repaired.
Yes. Below-ground areas can require specialist consideration because water can enter through walls, floors and joints. Depending on the building, waterproofing, tanking or other moisture-control measures may be appropriate.
