What is a Defect Survey?
Our Defect Surveys are designed to identify, diagnose, and provide solutions to specific issues affecting your property. Whether it’s a leaking roof, damp, cracks in walls, or suspected subsidence, our surveyors use a combination of expertise and advanced technology to get to the root cause of the problem.
As a RICS Regulated Firm, all surveys are carried out by qualified Chartered Surveyors with extensive experience in building pathology. We provide clear, independent reports that not only explain the issue but also offer practical advice and repair recommendations.

Frequently Asked Questions
1. What is a defect survey?
A defect survey is a focused property inspection that identifies and reports on specific issues such as cracks, dampness, roofing problems, or structural concerns. It provides clear explanations, photographs, and recommendations to help you understand the severity of the problem and the best course of action.
2. What types of defects can a survey uncover?
Common defects include:
- Damp, mould, or rot
- Structural cracks and subsidence
- Roofing and guttering issues

4. When should I arrange a defect survey?
You should consider a defect survey if:
