Specific Defect Report

What is a specific defect report?

Building survey reports typically offer pre-purchase or pre-lease guidance. Examples include Commercial Building Surveys, Level 3 Residential Building Surveys, and Level 2 Homebuyer Reports. They involve comprehensive inspection of the entire property.

If, however, your concerns are targeted toward a specific aspect or defect of a property, then opting for a Specific Defect Report might be more suitable — a focused building defect survey that examines one problem properly instead of every element briefly. This may be particularly relevant to individual concerns such as:

• inadequate or unusual construction
• structural movement and cracking
• decay and rot
• damp and condensation

Building defect surveys the panel provides

Damp surveys. Rising damp, penetrating damp and condensation produce similar stains and very different bills — an independent damp survey diagnoses the actual moisture source rather than selling a treatment. That independence matters: a surveyor with no chemicals to sell has no reason to find “rising damp” where a leaking gutter, a bridged cavity or poor ventilation is the real culprit.

Wet rot and dry rot surveys. Timber decay is a moisture problem before it is a fungus problem. A wet rot survey traces the leak or damp source feeding the decay and establishes how much timber is genuinely affected; suspected dry rot is treated with more urgency, because it can spread beyond the damp conditions that started it.

Cracking and movement. Most cracks are cosmetic; a few are progressive. The surveyor distinguishes historic settlement from active movement and explains which category yours falls into — and what evidence would change the answer.

Roof and rainwater defects. Leaks, slipped coverings and failed flashings — inspected directly, with a drone roof inspection where access is unsafe, or through the dedicated roof survey service.

What the surveyor inspects

The inspection is targeted rather than general: the defect itself, the building elements around it, and the moisture, ventilation or structural conditions that could be driving it. Expect moisture-meter readings around damp and decay, inspection of roof voids and subfloor voids where safe access exists, and photographs recording the evidence. Because the brief is narrow, the surveyor can give one problem the time a whole-house survey spreads across the entire building.

What the report contains

The specific defect report provides detailed insight into the area in question so as to address and resolve concerns: the likely cause of the defect, its severity and whether it is active, the sensible repair route, and what further investigation (if any) is justified. It is written so it can be handed to a builder or specialist contractor as a brief — so you buy the right repair rather than the one being sold. However, such a report will not cover the many other elements of the property, which a Full Building Survey does.

Specific defect report or full survey?

Choose the defect report when you already own the building, or when a purchase concern has narrowed to one identified issue; choose a Level 3 building survey when you are buying and the concern is one of several unknowns. Where movement is suspected to be progressive — for example widening cracks or dropping floors — a subsidence investigation may be the more appropriate instruction; the surveyor will advise which route fits your situation.

Fees and timescales

Fees are fixed and quoted before you instruct, based on the defect described and the property; reports are typically delivered within 3–5 working days of inspection, faster where a transaction or an insurer's deadline demands it. Specific defect reports sit within the panel's wider building surveying services.

When a defect becomes a dispute

Some defect instructions are already halfway to a legal matter — workmanship a builder will not put right, a damp problem a seller failed to disclose, an insurance claim the loss adjuster contests. Tell us at the outset: where proceedings are likely, the instruction is better placed with the panel's expert witness surveyors, whose construction defect experts prepare CPR Part 35-compliant evidence rather than a standard report.
