Handling Claims
For insurance-based work, clients benefit from a dedicated in-house loss assessor who takes over communication with the insurer. She prepares the full schedule of works, manages the claim from beginning to end and fights the client’s corner to secure the strongest possible settlement. It’s a professional, hands-off experience for the property owner and a smoother path to getting the work approved and completed.
Getting To Work
Using advanced leak detection methods such as tracer gas, thermal imaging and ground-level GPS tracking, we find and diagnose issues quickly and accurately. Once the source of the problem is confirmed, an assessment report is drawn up and the process moves forward without delay.
Ensuring You're Taken Care Of
Once the claim is settled, our trades team steps in. Restoration work is carried out efficiently and to the highest standard, with full project management throughout. Furniture can be removed and securely stored if needed. For more serious leaks or damage that makes a property uninhabitable, temporary accommodation can be arranged as part of the service.
