If your mobile phone has been exposed to liquid, moisture or steam, this diagnostic service assesses the resulting damage and provides a repair recommendation before further work is authorised.
Repair options
This service covers liquid-damage inspection, functional testing and a repair recommendation. No additional repair is carried out until the findings and quote have been approved.
Common symptoms
- The device has been exposed to liquid, moisture or steam
- The device does not power on or behaves unpredictably after exposure
- Charging, display, audio or camera faults appeared after liquid contact
- Internal corrosion or residue may need assessment
What is included
The mobile phone is inspected for signs of liquid exposure, corrosion and affected functions. We explain the findings and provide a repair recommendation before any additional work is carried out. Diagnosis is an assessment service rather than a completed repair, so no repair warranty applies.
Confirming your model
This diagnosis service is for mobile phones where the exact fault is not yet confirmed. Include the make and model when booking.
Repair process and turnaround
Turnaround is confirmed after we inspect the device and check the required component. The device is tested before and after the repair, and we contact you if inspection shows that a different component is responsible.

Frequently Asked Questions
What does the mobile phone water damage diagnosis include?
We open the device, assess the extent of liquid exposure across the logic board and key internal components, clean affected areas where possible, and report on what has been damaged. We explain clearly what is repairable and what the options are before any work begins.
How long does the water damage diagnosis take?
Most water damage diagnoses are completed within the same day at our Liverpool Street workshop. We will advise if your device needs more time.
Will my data be safe during the diagnosis?
We handle all devices carefully, but liquid damage can affect data storage components. If recovering data is a priority, let us know before the diagnosis begins so we can discuss the best approach.
What happens after the diagnosis?
We explain the findings and give you clear repair options. If you agree to proceed, the diagnosis fee is applied toward the repair cost. If you decide not to repair, the diagnosis fee still applies for the assessment carried out.
Is there a charge if the phone cannot be repaired?
The diagnosis fee is payable regardless of whether you proceed with a repair. If you choose to proceed, the fee is applied toward the cost of the repair. If you decide not to repair the device, the fee still applies for the time spent assessing it.
