Specialist Hotel & Guest House Leak Detection Services Across England, Scotland and Wales
ADI finds hidden water leaks in hotels, guest houses and spas using acoustics, thermal imaging and tracer gas, usually without opening up guest rooms.
Wet ceilings, a rising water bill or a boiler that keeps losing pressure are the usual signs, and room access is planned around your guests and maintenance team.

Comprehensive Water Leak Investigations for Hotel Properties
ADI traces hidden water leaks anywhere in a hotel, from guest bathrooms and risers to plant rooms, pools, kitchens, roofs and underground supply pipes. Choose the area that matches what you have noticed.
Roof Ingress & Building Façade Leaks
ADI locates roof and façade leaks that stain ceilings after rain, then reports the defect so your roofing contractor knows exactly what to repair.

Commercial Kitchens, Laundries & Drainage Systems
ADI investigates kitchen, laundry and drainage leaks with camera surveys and dye tests on the drains, gullies and pipework serving busy hotel services.

Plant Rooms, Boilers & Boosted Water Supplies
A boiler that keeps needing topping up, or a booster pump running through the night, points to a leak on the heating or boosted cold-water side. ADI traces both from the plant room outwards.

Swimming Pool, Spa & Balance Tank Leak Tracing
Daily top-ups can mean a leak in the pool shell, balance tank or filtration pipes, so ADI tests each part of the pool system separately.

Underground Water Mains & Outdoor Hotel Grounds
A water bill that keeps climbing with nothing wet indoors often means a buried supply leak between the meter and the building, or under car parks and gardens.
View this serviceNon-Invasive Leak Tracing Methods to Prevent Room Downtime
ADI finds most hotel leaks without opening up rooms, using tracer gas, acoustics, thermal imaging, borescopes and moisture mapping to pinpoint the source first. A room taken out of service costs a night’s takings every night it stays empty, so any targeted access is agreed with your team before it happens.
Tracer Gas Testing for Buried Pipework
Tracer gas finds leaks on buried supply pipes: a safe gas mix fed into the pipe escapes at the fault and is detected at the surface above it. It rises through soil, tarmac or a floor slab.
Acoustic Ground Microphones & Noise Correlation
Acoustic ground microphones locate pressurised pipe leaks by listening for escaping water through the surface. A correlator then times that sound between two points on the pipe to pinpoint the position.
Thermal Imaging Cameras for Heating & Ceiling Voids
Thermal imaging shows heat escaping from heating pipes buried in screed, and the cool damp patches that spread across ceilings below guest bathrooms.
Flexible Borescope Inspection Cameras
A flexible borescope lets the engineer see pipes and joints inside a void through a small drilled hole or behind a bath panel, without lifting floors.
Precision Moisture Mapping & Pressure Testing
Moisture mapping shows where damp is wettest and which way it is spreading across walls and floors, then pressure tests on each pipe section show which one is losing water.
Real-World Hotel Leak Tracing Case Studies
These three real ADI investigations show how leaks were traced in a refurbished hotel, a three-storey guest house and a detached hotel losing water. Each case explains what was found and what remained to be done.
July 2026
Garden Bank Boosted Supply Failure (Refurbished Hotel)
Weeks from reopening, the hotel's boosted supply to two garden taps lost pressure the moment the pump stopped. We traced it to a failed 25 mm fitting under a garden bank, replaced it and retested.
Found and repaired by ADI

March 2026
Top-Floor Shower Connection Leak (3-Storey Guest House)
Water was dripping through two ceilings in a three-storey guest house with a complicated tank-fed system. Thermal imaging and an endoscope led to an electric shower connection on the top floor.
Located by ADI, repaired later by the owner's plumber

January 2025
Unexplained Internal Water Loss (Detached Hotel Property)
A detached hotel was losing an estimated 17 litres of water an hour, and with the stopcock closed the meter stopped, so the loss was inside. A room-by-room inspection found the causes.
Diagnosed by ADI, repairs recommended
Read the investigationHow We Plan Access & Minimise Guest Disruption
ADI plans every hotel survey around your occupancy, agreeing room access, plant room keys and any water shut-off with your team before the engineer arrives. Housekeeping may have seen a stain before a guest reported it, and maintenance may know a pump has been cycling overnight, so bring both to the first call.
Step 1: Initial Phone Consultation & Quotation
Call the office with your postcode, the rooms affected and anything housekeeping or maintenance has noticed. The team explains the survey, quotes for your building and gives you current availability.
Step 2: Strategic Room Access & Plant Planning
Tell us which rooms are let, which can come out of service and who holds keys to the plant room, tanks and booster set. The engineer’s route through the building is then planned around your occupancy.
Step 3: On-Site Risk Assessment & Meter Isolation
On arrival the engineer goes through the risk assessment with your maintenance contact, then takes meter readings with the supply isolated to confirm water is being lost. Any shut-off is agreed with you first.
Step 4: Targeted Non-Destructive Testing
Acoustics, tracer gas, thermal imaging and moisture readings narrow the leak down room by room without damaging finishes. Where opening up is needed, the aim is a tile or a panel, agreed before it happens.
Step 5: Insurance-Compliant Written Survey Report
You get the findings in writing with photographs and recommendations, plus a risk assessment and method statement for commercial work. Policies differ, so ask your insurer what they need and we will make sure the report covers it.
Step 6: Targeted Repair Work & System Re-Testing
Pipework, drainage and pool leaks can be quoted and repaired, often on the same visit, then pressure tested to prove the repair holds. Roof and façade defects are reported for your roofing contractor.

See contact detailsFrequently Asked Questions (Hotel Leak Investigations)
Can you find a leak without tearing out hotel bathrooms or tiles?
Yes, in most cases ADI finds hotel bathroom leaks without removing tiles, using moisture mapping, thermal imaging, dye tests, tracer gas, acoustics and camera inspection first. These narrow the leak to a small area before anything is opened. Some jobs still need targeted access to confirm or repair the fault, and no survey can promise zero disturbance in every building, but we work to keep that to a tile or a panel rather than a room.
Will tests disturb staying guests or disrupt housekeeping?
Usually very little, because the engineer works room by room around your occupancy and agrees any water or heating shut-off with your maintenance contact first. Tell the office which rooms are let, which are out of order and when housekeeping is on the floor, and access is planned around that.
How quickly can an engineer attend an urgent hotel leak?
It depends on current availability, so call the office with your postcode and the team will tell you the earliest an engineer can reach your hotel. ADI has more than twenty-five engineers across England, Scotland and Wales, and hotels with water going where it should not are treated as urgent. We do not promise arrival times on a website; you get a real answer on the phone.
Do you carry out repairs during the same visit?
Often, yes: pipework, drainage and pool leaks can be quoted and repaired on the same visit, then pressure tested to confirm the repair holds. Roof and building-fabric leaks are located and reported for a roofer to fix. Repairs are charged separately from the survey and are quoted before any work starts.
Will the survey report be accepted by our insurance company?
The report is written for insurers, with photographs, findings and recommendations, but acceptance depends on your policy, so check what your insurer needs before the visit. Commercial work also includes a risk assessment and method statement. Insurers describe this work as trace and access; tell us what yours asks for and the report will answer it.
What access and information do you need from hotel staff before arrival?
We need someone who knows the building, access to every affected area and plant room, and parking within about 100 metres of the entrance for the equipment. That person should know where the meter, stopcocks and plant are and which rooms are affected. Access includes locked rooms and any neighbouring unit on a shared supply. If the pool is involved, its current level and how fast it is dropping.
