Before undertaking any remedial damp proofing action, it is important to ascertain the source of water/moisture ingress. There could be one or more sources, such as penetrating damp, plumbing defects, condensation, bridging of the damp proof course (dpc) or absence of effective damp proofing resulting in rising damp.

Dampness in buildings in Oxford

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

Moisture could pass into the fabric of a building, resulting in dampness, through many routes including building defects, broken or leaking pipes, poor maintenance and lack of effective damp proofing measures.

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

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

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). 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;

Rising damp in Oxford

Internal building defect or other sources of dampness in Oxford

  • The ingress of water through the failure of a water carrying appliance, the spillage of water or other source of moisture
  • Plumbing faults such as leaking valves, leaking radiators, hot water tank, washing machines or waste pipes.
  • Bath or shower overflow or splashing
  • Condensation on un-insulated cold water pipes.
  • Lack of adequate roof space ventilation leading to condensation and causing mould growth
  • Blocked up fireplaces causing condensation to form in the void.
  • Broken, cracked or blocked drains

The movement of moisture through materials in Oxford by capillary action

  • Absence of physical Damp proof course (DPC) or damp proof membrane (DPM)
  • Breakdown or failure of physical Damp Proof Course
  • Ineffective chemical damp proofing or plastering
  • Bridging of damp proof course by increase external ground levels, external render, internal solid floors, blocked cavity

Penetrating Dampness in Oxford

The ingress of water into a building in Oxford could be the result of a building defect such as:

  • Blocked or broken guttering
  • Blocked or broken downpipes
  • Defective external rendering or pointing
  • Defective weatherproof seals on doors and windows
  • Roofing defects such as loose or missing tiles/slates, damaged or missing flashings, or damaged coping
  • No weatherboard on doors
  • Bridged wall cavity.
  • Overflow pipe continuous running
  • Lack of drip beading on rendered walls or blocked drip grooves on cills
  • Porous or cracked bricks


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.

Condensation occurs when air with high water vapour content encounters cool surfaces (below dew point temperature). The water condenses from the air, resulting in the formation of water droplets on the cold surfaces. Extreme condensation can lead to dampness on walls, mould growth and the rotting of window sills. The presence of black spot mould on walls is an indication of excessive condensation.
