Opening a wet floor with the landlord’s agreement
A tenant at a London property reported running-water noise and swelling laminate. High moisture readings were found around the kitchen floor. Acoustic checks and pipe locating narrowed the suspected area, and the landlord authorised opening the floor and repairing the pipe.
A pinhole was exposed in the cold mains pipe beneath wet screed. The damaged section was replaced and the mains flushed. A 15-minute check of the hot and cold pipework at standing mains pressure recorded no measurable loss at that time. The opening was left under a temporary plywood cover with hazard tape; specialist drying and permanent floor reinstatement were still needed.
What has the tenant noticed?
Choose the closest match to see which survey fits, then call with the property’s postcode to confirm that survey is available there.
Hidden plumbing leaks
Photograph the changing patch and identify affected rooms, including any adjoining home that may need access.
Tell us which room is affected and when the mark first appeared.
Heating leak investigation
Share pressure records and earlier boiler checks so ADI can assess whether pipework testing is appropriate.
Note how often the pressure drops and what has already been checked.
Water mains leak detection
Check which homes use the meter and provide consumption records before a buried supply is investigated.
Have the property postcode and any recent meter readings to hand.
Bathroom leak detection
Record which fitting is used before water appears. Supply, waste and seals may need separate checks.
Explain whether the water appears after the bath or shower is used.
Roof and building leaks
Note the weather and affected surfaces. ADI investigates ingress; roofing and building repairs need the appropriate trade.
Keep dated photographs and note the weather when the leak appears.
Drain investigation
Provide inspection-point locations and previous drainage reports so suitable camera access can be discussed.
Let the team know about existing inspection points and previous drain work.
Planning a survey for your type of let.
Each kind of rental property needs access organised a little differently. Choose yours to see what to arrange before the engineer arrives.

Leak detection questions for Greater London
Coverage, addresses near the county boundary, tenanted homes and cost. Select a question to read the answer.
Which parts of Greater London does this page cover?
This page follows the ceremonial county of Greater London: the 32 London boroughs, including Westminster, but excluding the separate City of London. The places listed are examples within Greater London, not a complete list or a record of past jobs. Call with the full postcode to discuss the property and current availability.
Coverage across BritainThe property is in a conservation area or listed building. Can a survey still go ahead?
Tell the office about any protected fabric and access restrictions before booking. Non-invasive tests help narrow the search; access for confirmation or repair may still be needed. Agree any opening up separately and obtain the relevant advice on the proposed work.
Preparing a rental property for a surveyCan the survey go ahead while the tenant is living there?
Surveys are arranged around the tenancy, so the key is agreeing access in advance. Tell the tenant when the engineer is due, agree who will be there, and make sure the meter, the stopcock and the affected rooms can be reached. Keep your own number available on the day for questions about the property.
Preparing a rental property for a surveyHow much does a leak survey cost in Greater London?
ADI quotes for each property based on the investigation it needs, so there is no single price for the county. Before booking, confirm the total including VAT, what the survey covers and any charges for extra access or repairs.
