Introduction
Building surveyors play a crucial role in the property market. Whether purchasing a home, investigating building defects,
resolving construction disputes or advising property owners on maintenance, Chartered Building Surveyors provide expert
professional advice on the condition and performance of buildings.
In London, where the property market includes a wide range of historic and modern building types, the role of building
surveyors is particularly important. Victorian terraces, Edwardian houses, 1930s suburban properties and modern apartment
developments all present different construction characteristics and potential risks.
This guide explains what building surveyors do, when building surveys are required, how Level 3 Building Surveys work and
why instructing experienced building surveyors in London is essential when buying or maintaining property.
What Does a Building Surveyor Do
A building surveyor is a property professional who specialises in the construction, condition and maintenance of buildings.
Building surveyors provide advice on:
• Property condition and structural defects
• Building surveys prior to property purchase
• Construction disputes and defective building works
• Dilapidations and leasehold property issues
• Party wall matters
• Property maintenance and repair strategies
Chartered Building Surveyors are typically members of the Royal Institution of Chartered Surveyors (RICS) and operate
within recognised professional standards.
What is a Building Survey
A building survey is a detailed inspection of a property carried out by a professional building surveyor.
The purpose of the survey is to assess the condition of the building and identify defects that could affect the
property’s structural integrity, safety or value.
Typical elements inspected during a building survey include:
• Roof structures and coverings
• External walls and masonry
• Windows and external joinery
• Structural movement and cracking
• Dampness and moisture issues
• Timber defects and decay
• Internal finishes and building services
What is a Level 3 Building Survey
A Level 3 Building Survey is the most comprehensive residential property survey available.
Previously known as a full structural survey, the Level 3 Survey provides a detailed analysis of the property’s
construction, condition and potential defects.
Level 3 Building Surveys are particularly recommended for:
• Older properties
• Buildings that have been extended or altered
• Properties with visible defects
• High value property purchases
Why Building Surveys Are Important in London
London’s housing stock includes many properties that are more than 100 years old. Older buildings often contain
construction techniques and materials that differ significantly from modern buildings.
Common issues identified by building surveyors in London include:
• Damp penetration through solid brick walls
• Roof deterioration in slate and tile coverings
• Structural movement caused by settlement
• Timber decay within floors and roofs
• Defective alterations and extensions
A professional building survey helps property buyers understand these risks before committing to a purchase.
Common Defects Identified During Building Surveys
Building surveyors regularly identify defects that may affect the condition or value of a property.
Common defects include:
• Structural cracking and movement
• Damp penetration and condensation
• Roof defects such as slipped tiles
• Chimney deterioration
• Timber rot and woodworm
• Defective rainwater goods
Identifying these issues early allows property owners to plan repairs and avoid unexpected costs.
Types of Building Surveys
Building surveyors may provide several different types of property inspection depending on the client’s needs.
Common survey types include:
• Level 2 Homebuyer Surveys
• Level 3 Building Surveys
• Specific defect inspections
• Schedule of condition reports
• Dilapidations surveys
• Expert witness reports for litigation
Building Surveyors and Construction Disputes
Building surveyors are often involved in construction disputes where building works are defective or incomplete.
In these situations surveyors may:
• Inspect building defects
• Prepare technical reports
• Estimate remedial works
• Provide expert witness evidence in court
Expert witness building surveyors play an important role in helping courts understand technical construction issues.
