An introduction to defects surveyors frequently report and the follow-up they may recommend. 

Every property is different, but some issues appear regularly in survey reports. The significance can range from routine maintenance to a need for urgent specialist investigation. 

Damp and moisture 

Damp can have several causes, including condensation, leaks, defective rainwater goods, high external ground levels or moisture entering through the building fabric. The right remedy depends on the cause, so avoid assuming that every damp reading needs the same treatment. 

Roof defects 

Surveyors may report slipped or damaged coverings, defective flashings, worn flat roofs, blocked gutters, issues with chimneys or concerns visible within the roof space. Limited access can mean a roofer or other specialist needs to inspect further. 

Timber decay and infestation 

Visible signs can include softened timber, staining or small flight holes. The report may recommend further investigation to confirm whether there is active decay or infestation and what treatment or repair is needed. 

Movement and cracking 

Cracks can arise from many causes, including normal settlement, thermal movement or more significant structural issues. The pattern, width, location and surrounding evidence all matter. A structural engineer may be recommended where the cause or significance is uncertain. 

Services and certification 

A survey includes only a visual check of accessible services. Age, visible condition or missing records may lead the surveyor to recommend tests by an electrician, heating engineer, drainage contractor or other competent specialist. 

Alterations and extensions 

The surveyor may identify changes that your conveyancer should investigate, such as whether appropriate permissions, approvals, warranties or certification exist.
