Dampness in buildings in Windsor

Moisture can enter the fabric of a building, leading to 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 in Windsor and recommend a specialist damp proofing survey be carried out by a PCA and BWPDA approved company in Windsor.

The specialist damp survey 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 Windsor 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.

Sever condensation

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


Condensation in Windsor occurs when air with a high water vapour content comes into contact with cool surfaces (below dew point temperature). 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. 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.

Penetrating Dampness in Windsor

  • Blocked or broken guttering

  • Absence of physical Damp proof course (DPC) or damp proof membrane (DPM)

Biocraft Serves Windsor – Town overview

Windsor is a historic market town and unparished area in the Royal Borough of Windsor and Maidenhead in Berkshire, England. It is widely known as the site of Windsor Castle, one of the official residences of the British Royal Family.

The town is situated 23 miles (37 km) west of Charing Cross, London, 7 miles (11 km) south east of Maidenhead, and 21 miles (34 km) east of the county town of Reading. It is immediately south of the River Thames, which forms its boundary with its ancient twin town of Eton. The village of Old Windsor, predates what is now called Windsor by around 300 years; in the past Windsor was formally referred to as New Windsor to distinguish the two.
