Specific Defect Reports in London

Independent Advice on a Specific Problem

Not every concern needs a full building survey. If you have one problem, such as a crack that seems to be getting wider, a damp patch that keeps coming back or a roof that has started to sag, a specific defect report looks at that issue in detail and tells you what is causing it and what to do about it.

Reports are prepared by our associate chartered building surveyor, who has more than 10 years’ post-qualification experience and works to current RICS guidance. He does not carry out or sell repairs, so the advice is independent of any contractor.

When a defect report helps

  • You own the property and want to understand a problem before paying for repairs
  • You are buying and a survey has recommended further investigation of a defect
  • You have conflicting advice or very different quotes from contractors
  • You are a landlord, managing agent or tenant and need an independent view
  • You need clear evidence in a disagreement with a builder, neighbour or insurer

Defects We Investigate

Cracking and movement

Distinguishing historic, stable movement from progressive movement such as subsidence, heave, failing lintels or wall tie corrosion. Where needed, crack monitoring or a structural engineer is recommended.

Damp and mould

Condensation, penetrating damp, rising damp and leaks. For a full diagnosis of damp across a property, see our damp and mould surveys.

Roofs and chimneys

Leaks, sagging or spreading roofs, failed flat roof coverings, defective flashings and chimney stacks.

Walls, render and brickwork

Spalling bricks, failed pointing, cracked or hollow render, and bulging or leaning walls.

Timber and floors

Wet rot, dry rot, woodworm, and springy or sloping floors.

Problems after building work

Defects in extensions, loft conversions and refurbishments, including whether the work has been carried out to a reasonable standard.

What the Report Includes

Every report follows the same clear structure, so you can see at a glance what has been found and what to do next.

  • Property description, including the construction type and approximate age
  • Observations from the inspection, with photographs
  • Analysis of the likely cause, not just the symptoms
  • Recommendations for repair, in order of priority
  • Further investigations only where they are genuinely needed, such as a drainage CCTV survey or a structural engineer
  • Appendix of site data such as moisture readings and site notes

The inspection is non-invasive. The surveyor will not lift fitted floor coverings or open up construction without your agreement, but will tell you if opening up is needed to reach a firm conclusion.

Defect Report Fees

Guide fee

From £500 + VAT

For a single defect at a residential property. The fee depends on the nature of the defect, the size of the property and the extent of inspection needed, and is confirmed before you instruct.

If the inspection shows that a wider survey is needed, you will be told before any further cost is incurred. For a survey of the whole property before you buy, see our RICS Level 1, 2 and 3 surveys.

Defect Report FAQs

A focused inspection and report on one problem, or a small number of related problems, in a property. It explains the cause and recommends a remedy rather than reporting on the whole building.

A Level 3 Building Survey covers the whole property. A defect report looks only at the issue you are concerned about, in more depth and at a lower fee.

From £500 + VAT for a single defect at a residential property. A fixed fee is confirmed before you instruct.

Most cracks in older London houses are historic or cosmetic, but some indicate ongoing movement. The width, shape, location and whether the crack is changing all matter, and that is what the inspection establishes.

No. The surveyor is independent and does not carry out or sell repairs, so the advice is not influenced by the cost of the work.

Yes. A clear, independent report is often useful evidence in disagreements with builders, neighbours or insurers. If you need a formal expert witness report for court, tell us at the outset, as different rules apply.

Sometimes. Many defects can be diagnosed and resolved by a building surveyor, but where structural calculations or a design are needed, the report will say so.
