Dampness in buildings in Basingstoke

Moisture can enter the fabric of a building in Basingstoke, 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).

It is important to determine the source of water/moisture ingress before taking any remedial damp proofing action in Basingstoke. There may 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 in Basingstoke.

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

The specialist damp survey in Basingstoke 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 Basingstoke 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 Basingstoke.

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


Condensation in Basingstoke 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 in Basingstoke. 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.

Biocraft Serves Basingstoke – Town overview

Basingstoke is the largest town in Hampshire. It is situated in south central England, and lies across a valley at the source of the River Loddon. It is located 30 miles (48 km) northeast of Southampton, and 19 miles (31 km) northeast of the county town and former capital Winchester. According to the 2011 census Basingstoke (including its outer suburbs) had a population of 107,355.[a] It is part of the borough of Basingstoke and Deane and part of the parliamentary constituency of Basingstoke. Basingstoke is often nicknamed “Doughnut City” or “Roundabout City” because of the number of large roundabouts.

Basingstoke is an old market town expanded in the mid 1960s as a result of an agreement between London County Council and Hampshire County Council. It was developed rapidly after World War II, along with various other towns in the United Kingdom, in order to accommodate part of the London ‘overspill’ as perceived under the Greater London Plan in 1944.
