Thermal imaging
Shows surface temperature patterns that help narrow down where hot or cold water may be escaping. It does not see through walls.
Leak investigations for blocks across Buckinghamshire
For managing agents and RMC or RTM directors with blocks anywhere from Olney in the north to Taplow and Iver in the south. Call with the postcode to talk through the leak, the building and who can give access.
Leak investigation services in Buckinghamshire
A leak in a block may show first as a stain in one flat. The source can be a neighbour’s pipework, a shared riser or the supply running under the car park, and each of those needs a different survey.
How a block investigation works
Most of the arranging happens before anyone arrives, because access across several homes takes planning.
Call with the block details
Give the postcode, where water is appearing and which flats or communal areas are affected. An enquiry does not confirm attendance.
Agree the scope and access
Before booking, agree what will be investigated, the price and anything excluded. Name who will arrange access to flats, risers and plant rooms.
Survey on site
The engineer uses the methods that suit the agreed scope. Opening-up, isolation or extra access is agreed first with whoever instructed the work.
Report and next steps
The report sets out what was accessed, what was found and what remains unconfirmed. Repairs are agreed and priced separately.
Detection methods and equipment
ADI selects the equipment to suit the agreed investigation. Each method has limits, and a useful report says what they were.
Moisture mapping
Records readings across floors and walls to show how far water has spread. A reading on its own is not a drying sign-off.
Acoustic detection
Listens for water escaping from a pressurised pipe, and correlation compares two points to estimate where the leak is.
Tracer gas
Put into suitable pipework under controlled conditions, then detected where it comes up through a floor or the ground.
Pressure testing
An isolated section either holds pressure or it does not, which tells a leaking circuit from a sound one. A failed test may not pinpoint the fault.
Cameras and dye
An endoscope looks into voids through a small opening, CCTV inspects drains, and dye can confirm where water flows.

Useful local information
- Councils
- Buckinghamshire Council has covered the county outside Milton Keynes since April 2020, replacing the county council and the Aylesbury Vale, Chiltern, South Bucks and Wycombe district councils. Planning and building-control files from before then may still carry the old district name.
- Drinking water
- Thames Water, Anglian Water and Affinity Water each supply parts of the county, and the supplier can change between neighbouring areas. Go by the company named on the block’s water bill.
- Supply pipes
- Whichever of those companies is on the bill can confirm where its pipework ends and the block’s supply pipe begins, and whether a leakage allowance applies. Read about shared supply responsibilities.
- Roads and pavements
- Digging up a public road or pavement needs the highway authority’s agreement. Here that is Buckinghamshire Council or Milton Keynes City Council, apart from motorways and trunk roads.
Sources checked 15 September 2026: Buckinghamshire Council’s local drainage context, the civil parish register, the water companies’ published supply areas and the post town recorded for each place. Towns are places with a town council, plus High Wycombe, which has none.
A written record after the visit
The attending engineer prepares the investigation report: the areas accessed, what was found and what still needs checking.
Use it to brief a repair contractor, update residents and give an insurer the evidence.

Questions about coverage and surveys
Is Milton Keynes included?
Yes. Milton Keynes is part of ceremonial Buckinghamshire but has its own city council, so its towns are grouped separately above.
Our address says Slough or Maidenhead. Is that covered here?
If the block is in Burnham, Farnham Common or Taplow, yes. Those Buckinghamshire places use a Slough or Maidenhead post town. Coverage is checked against the full postcode either way.
Do you cover places that are not listed?
Yes, subject to availability. The places on this page are examples, and coverage is checked against the full postcode, so call with it even if the block is in a smaller village.
How soon can an engineer attend?
That depends on the postcode, the system involved and the appointments available. An attendance time is confirmed only when ADI accepts the booking. If water is putting people or electrics at risk right now, use the building’s emergency arrangements first.
Does the investigation include the repair?
Finding the leak and repairing it are agreed and priced separately. ADI does not undertake roof or building repairs.
What does a survey cost?
The price depends on the building, the system and the access needed. Ask for the survey price, VAT and anything excluded before you book.
Can the report go to our insurer?
Yes. It records what was inspected and found, which helps an insurer or broker consider the claim. It cannot decide who pays or guarantee that a claim is accepted. Read about trace and access.
