Successful damp treatment starts by determining whether the moisture is coming from inside the building, outside the building, the ground below it or a concealed defect.
Our damp surveys in Harrow assess more than the affected piece of plaster.
A survey may consider the height and shape of the damp, whether it changes after rainfall, how the room is ventilated, the condition of external brickwork and render, guttering, chimney details, window surrounds, external ground levels, suspended floors and previous alterations.
This wider view is particularly important in older or converted Harrow properties where several different issues can exist at the same time.
A bedroom may have a genuine condensation problem while an adjacent wall is also being affected by a leaking gutter. Low-level damp might resemble rising damp even though an external path is bridging the damp-proof course.
Where the moisture route is particularly difficult to identify, our survey and diagnostic services can provide further investigation.
Many established Harrow neighbourhoods contain older terraced and semi-detached homes where bay windows, chimney breasts, suspended floors and traditional brick elevations remain important parts of the building.
As these properties age, relatively small external defects can create noticeable internal damp.
Weathered pointing around a bay, cracks in render, defective rainwater goods or deterioration around a window can allow water to reach internal finishes. At floor level, blocked airbricks or raised paving may affect ventilation and increase moisture around timber.
Previous renovations can complicate the picture further. An older wall that has been repeatedly plastered, lined or coated may retain moisture behind its finished surface.
Our approach is to establish what part of the building is actually failing rather than simply covering the internal damage.

Bay windows are a common place for homeowners to first notice damp.
The problem might appear as a patch below a window, staining at the side of the bay, mould around the reveal or damaged plaster close to the ceiling of the bay.
Several different defects can create these symptoms. Water may be entering through failed pointing or window seals, the roof over the bay may be leaking or rainwater may be tracking through damaged external masonry.
Condensation can also develop because bay windows contain several exposed surfaces that can become colder than the rest of the room.
The behaviour of the patch is useful. Damp that becomes significantly worse after rain is more likely to involve external water ingress, while black surface mould that develops during colder weather may point more strongly towards condensation.
Where external moisture is identified, our penetrating damp treatment can address the underlying cause.
Protect your home before the problem gets worse. Our friendly surveyors will diagnose the issue, explain the results, and recommend the most effective treatment.
