Local knowledge
How Westminster properties leak
Westminster housing is dominated by stucco terraces, mansion blocks and serviced apartments. Mansion blocks with concealed risers need landlord and porter coordination; we isolate, trace and document for freeholders and managing agents.
Knowing the local building stock matters: it tells us where the pipework usually runs, which materials to expect, and which detection method will get to the answer fastest, before we arrive.

Common leak problems in Westminster
Concealed Pipework in Mansion Blocks
Leaks within concealed risers in Westminster's mansion blocks are a major concern. Our process involves coordinating with landlords and porters to isolate the supply and trace the leak source. We provide the detailed documentation that freeholders and managing agents require for insurance claims, ensuring a clear audit trail.
Leak Damage to Stucco & Historic Fabric
Persistent leaks in stucco-fronted terraces can lead to significant internal damage and compromise the historic fabric. We use non-invasive trace and access techniques to pinpoint the issue with minimal disruption. Our reports detail the cause and necessary repairs, which is critical evidence for insurers assessing structural damage claims.
High-Density Serviced Apartment Systems
The constant turnover in serviced apartments puts immense pressure on plumbing systems, leading to wear and joint failures. We systematically test and document the condition of shared supply lines and individual units. This evidence is vital for insurers to determine liability and approve remediation costs between multiple parties.
Managing Agent Coordination for Access
Effective leak resolution in Westminster's multi-occupancy buildings hinges on authorised access. We manage the procedural coordination with managing agents and porters to gain entry for inspection. Our documented access logs and cause-and-effect reports form the basis for insurers to validate claim procedures and cost recovery.

How to Choose a Leak Detection Company in London
Choosing between companies you cannot assess technically is the hard part of a hidden leak. Six questions separate a survey from a guess, and the answers tell you more about the outcome than any review ever will.
Leak detection in Westminster, FAQs
How quickly can you attend a leak in Westminster?
Same-day appointments are usually available in Westminster, and next-day almost always. If water is actively escaping, tell us when you book. Live leaks are prioritised and we can talk you through isolating the supply while an engineer travels.
Do you charge if you can’t find the leak?
No, where the leak is inside your own property. Attend a confirmed live leak in Westminster, fail to locate it, and the detection fee is waived. The promise stops at your boundary: if the survey shows the water is arriving from an adjoining property, a communal pipe or the supplier's main, that leak has been found and the visit is charged.
Can you provide a report for my insurer?
Yes. Trace and access reports documenting the cause, precise origin and affected areas are available for every Westminster detection visit, typically within 48 hours. They are structured the way UK loss adjusters expect.
Which parts of Westminster do you cover?
All of it, including Marylebone, Pimlico, Paddington, Mayfair, St John’s Wood. We cover every London borough, so coverage never depends on which side of a postcode line you live.
There is a freeholder, a head lessee and my own lease. Who insures the building?
Usually whichever party the leases oblige to insure, which is frequently the head lessee where one exists, with the cost recovered through service charge from the underlessees. Occasionally the freeholder insures and the head lessee simply collects. The answer is in the covenants rather than in general practice, so the reliable route is to read the insurance covenant in your own lease and ask the managing agent to confirm the arrangement above it. Doing that before a loss removes the most common week of wasted time in these buildings.
My flat is damaged but the source is in a commercial unit below. Who deals with it?
Mixed use is common in Westminster and it complicates matters, because the commercial occupier's interests, insurance and access arrangements differ from a residential leaseholder's. The building policy arranged by the freeholder or head lessee normally covers the structure regardless of which unit the water came from. Access to a commercial demise generally runs through the same landlord's right of entry provisions. What is worth avoiding is trying to deal directly with the business, which rarely has authority and often has no idea what its lease says.
The reinstatement involves ornate plaster and specialist joinery. Will the policy fund it?
Then the argument will be about specification rather than entitlement. Indemnity is directed at putting you back in the position you occupied, so genuine matching work on decorative plaster, panelling or joinery is normally arguable rather than a betterment, but it has to be established at scope stage with a description of what is actually there. Photographs, any historic records and a specialist's assessment of the existing work all help. A figure agreed on general rates will not fund conservation quality reinstatement, and reopening it afterwards is far harder.
The block wants access to my flat to investigate a leak elsewhere. Do I have to agree?
Long leases normally contain a covenant permitting the landlord entry on notice to inspect and remedy defects affecting other parts of the building, and refusing reasonable access can put you in breach and expose you to the consequences of continuing damage. The practical approach is to agree a time, be present, and ask for confirmation in writing of what will be done and how anything opened will be reinstated. Access granted promptly also tends to be access granted narrowly, which is in your interest.
Is a serviced apartment building handled differently?
Often, because the management is commercial and the occupancy arrangements may be licences rather than leases, so an occupier may have no property interest at all. The building will be insured by its owner and claims handled through the operator, with the occupier's position limited to their possessions and their contract. If you own a unit within such a building, read what the management agreement says about insurance and about who instructs repairs, because it may differ considerably from a conventional residential block.
