Dampness in buildings in Oxford

Moisture can enter the fabric of a building, resulting in dampness, in many different ways including building defects, broken or leaking pipes, poor maintenance and lack of effective damp proofing measures.

Movement of moisture or the presence of excessive levels of moisture in building materials can result in salt staining, plaster deterioration, or spoiling of decorations. Timbers that are (subjected) exposed to continual dampness are at risk from wood destroying fungi (wet and dry rot).

It is important to determine the source of water/moisture ingress before taking any remedial damp proofing action in Oxford. There may be one or more sources, such as penetrating damp, plumbing defects, condensation, bridging of the damp proof course (dpc) or lack of effective damp proofing resulting in rising damp.

Valuation and building surveys will frequently identify damp in properties in Oxford and recommend a specialist damp proofing survey be carried out by a PCA and BWPDA approved company in Oxford.

The specialist damp survey in Oxford should identify the possible source(s) and recommend corrective action, such as repairing external/internal defects, reducing external ground levels to below the level of the damp proof course, installing French drains, improving heating and ventilation or the installation of a chemical damp proof course.

Specialist damp surveys in Oxford should be carried out by a qualified damp proofing surveyor with a minimum of a CSRT (certificated surveyor in remedial treatments) qualification as required by the Property Care Association (PCA) and the British Wood Preserving and Damp Proofing Association (BWPDA). All Biocraft surveyors have achieved the CSRT & CSSW qualification to carry out damp surveys in Oxford.

The most common sources of moisture ingress that can be found in buildings during specialist damp proofing surveys in Oxford are as follows;


Condensation occurs when air with a high water vapour content comes into contact with cool surfaces. The water condenses from the air, resulting in the formation of water droplets on the cold surfaces. Excessive condensation can lead to the rotting of window sills, dampness on walls, and mould growth. The presence of black spot mould on walls is an indication of excessive condensation.

Reducing the moisture loading in the air and/or improving the ventilation is the most effective method of dealing with condensation in Oxford. Dehumidifiers are costly to run, require emptying and should only be considered as a temporary measure. Dehumidifiers and anti-condensation paints just treat the effects and do not remove the cause. Whole home ventilation systems are a cost effective method of dealing with the cause of condensation and removing the effects.
