A full building survey is the most thorough form of property inspection available. It provides a detailed assessment of the building's construction, condition and defects, together with practical advice on repairs, maintenance and any further investigations needed. Here is what our chartered surveyors look for.
The surveyor inspects the roof covering for missing, slipped or damaged tiles or slates, the condition of flashings, valleys and ridges, and the state of the roof structure from within the loft space. They check for signs of timber decay, woodworm, inadequate ventilation, water ingress and any alterations that may have compromised the structural integrity of the roof.
The external walls are examined for cracking, movement, bulging, erosion of pointing and the condition of render or cladding. The surveyor assesses whether any movement is historic and stable or ongoing and progressive. In London period properties, common issues include bay window movement, lintel failure, sulphate attack on brickwork and defective pointing.
Internal inspections cover every accessible room, checking for damp, condensation, timber decay, cracking, uneven floors and the condition of finishes. The surveyor uses a moisture meter to identify areas of elevated damp readings and assess whether the source is rising damp, penetrating damp or condensation. The condition of joinery, plasterwork and internal walls is also assessed.
While a building survey is not a specialist services test, the surveyor visually inspects the electrical installation, heating system, plumbing and drainage for obvious defects, age-related concerns and compliance issues. The grounds, boundaries, outbuildings and any external features are also covered. Where further investigation is needed, the report recommends appropriate specialist inspections, such as a drain survey or electrical test.
A building survey (Level 3) is the most comprehensive inspection with detailed analysis and repair advice. A homebuyer report (Level 2) uses a traffic-light system and suits conventional properties in reasonable condition. For older or altered properties, a full building survey is recommended.
The site inspection typically takes two to four hours depending on property size. The report is usually delivered within five to ten working days. Larger or more complex properties may take longer.
A building survey is visual and non-destructive, but an experienced surveyor identifies signs of hidden defects such as damp staining, cracking patterns or uneven floors. Further specialist investigation is recommended where hidden defects are suspected.
Yes. New builds can have workmanship and finishing defects that snagging alone may miss. A building survey provides independent assurance and identifies issues to address within the builder's warranty period.
