Georgian squares, Victorian villas and converted houses in Camden
Camden's housing is older than most of London's. Bloomsbury is built around Georgian squares and terraces, Hampstead keeps Georgian houses in its old village streets, and Belsize Park and Primrose Hill are known for large Victorian villas in stucco or red brick. Kentish Town, Camden Town and Chalk Farm are mostly Victorian terraces, while the former railway lands at King's Cross now hold new apartment buildings. Council estates are part of the picture too, including the Grade II* listed Alexandra Road Estate in South Hampstead, completed in 1978.
A large share of those period houses has been split into flats. In a converted villa in Belsize Park or a terrace in Kentish Town, the pipes for three or four homes often share the same floor voids and pass through each other's ceilings. One original supply pipe may still feed the whole building, with a branch added for each flat over the years. When water appears, the first task is working out which home, and which of several pipe runs, it belongs to.
Basements, lightwells and ground water under Camden
Many Camden terraces have a lower ground floor behind a front lightwell, and plenty of homes have had new basements dug beneath them. Rooms like these sit below the street and the garden, so damp can come from a plumbing leak, from rain getting in around the lightwell, or from water in the ground. Camden's own basement planning guidance notes that parts of the borough have unstable subsoils and underground streams, and it can require a hydrogeological assessment for new basements, for example near the Hampstead Heath ponds catchment.
For a homeowner, that means a wet basement wall is not proof of a burst pipe. A damp and moisture survey, priced from £250 to £450, maps where the moisture sits, while meter and pressure tests show whether the supply or the heating is losing water at all. Together they tell you whether you need a plumber, a drainage contractor or a waterproofing specialist before anyone cuts into a tanked wall.
Conservation areas and opening up floors in Camden
Camden has 40 conservation areas covering about half of the borough, including Bloomsbury, Hampstead, Belsize, Primrose Hill and King's Cross, and a good number of houses are also listed. In a listed building, works that affect historic fabric such as original boards, panelling or decorative plaster can need listed building consent, so it pays to know exactly where a leak is before anything is taken apart.
Non-invasive tracing makes that possible. Thermal imaging, from £150, shows heating and hot water pipes behind lath and plaster or under boards without disturbing them. Acoustic detection, also from £150, listens for pressurised water through solid floors and stone steps. A trace and access survey, from £350 to £450, pairs the search with a written record of where the leak is and how it was found, which is useful to share with a freeholder, a conservation officer or an insurer.
Leaks we often trace in Kentish Town, Belsize Park and King's Cross
In converted terraces the usual finds are a weeping joint under a first floor bathroom, heating pipes notched through joists above a neighbour's ceiling, and an old supply pipe running beneath the front steps. Homes built before about 1970 may still have lead on the supply side, and joints on it often give way where the pipe turns up into the building.
Newer flats around King's Cross and in recent conversions tend to have plastic pipework in screed and underfloor heating. A slow leak there spreads through the screed and usually shows first in the flat below. Under-floor detection costs £300 to £700, and a combined survey using more than one method is £250 to £500.
The Alexandra Road Estate is a special case. Its original heating runs through coils set in the walls between homes and is a communal system, so residents who suspect a heating leak should report it to Camden Council as well as looking for signs inside the flat.
Getting ready for a survey in a Camden flat or house
Thames Water supplies Camden. It owns the pipe up to the outside stop valve, usually under a small cover in the pavement, and the supply pipe from there into the building is the owner's. In a converted house with one shared supply, the owners it serves share that responsibility, so bring the freeholder or managing agent in early.
Before the visit, find your internal stop tap, note the meter reading if you have a meter, and write down the boiler pressure while the system is cold. If water is coming through from the flat above, ask your neighbour for access on the day. When it is already running through a ceiling, emergency detection is from £300 in working hours and £450 out of hours. Call 020 3912 0200.

Leak Detection in Camden: Common Questions
Is the damp in my Camden basement a leak or ground water?
It can be either, and parts of Camden do have underground streams and difficult subsoils. We first test whether your supply or heating is losing water, using the meter and pressure readings. If both hold steady, a plumbing leak is unlikely. Moisture mapping then shows the pattern of the damp, and the written report explains what was found so you can call the right trade.
Do you cover Kentish Town, Belsize Park, Primrose Hill and King's Cross?
Yes. We cover the whole London Borough of Camden, including Camden Town, Chalk Farm, Kentish Town, Gospel Oak, Belsize Park, Primrose Hill, Hampstead, West Hampstead, Swiss Cottage, Somers Town, King's Cross, Bloomsbury and Holborn. The same methods and published prices apply across the borough, whether the job is a mansion flat, a converted villa or a new build apartment.
Can you find a leak in a listed Hampstead house without lifting floorboards?
In most cases the search itself needs no lifting. Thermal imaging, acoustic listening and tracer gas all work from the surface, and the survey ends with a marked leak position. The repair may still need a small opening at that point. If the house is listed, check with Camden Council before any work that affects historic fabric.
Who is responsible for the supply pipe in a converted Camden house?
Thames Water is responsible up to the outside stop valve. From there, the supply pipe belongs to the property. Where one pipe serves every flat in the building, the owners it serves share the responsibility, and the lease or freehold arrangements usually set out how costs are split. Our report shows where the leak is, which helps everyone agree the next step.

Leak detection in Belsize Park
NW3Mansion blocks and substantial villas in multiple occupation, where a single riser fault affects several flats at once.
Leak detection in Chalk Farm
NW1, NW3Victorian terrace with a lot of loft and basement conversion, so heating pipework runs through spaces that were never meant to carry it.
Leak detection in King's Cross
N1C, WC1New build apartments and converted warehouses, where a leak in a communal service void needs building access before anything can be isolated.
Leak detection in Kentish Town
NW5Dense Victorian terrace, commonly with the original supply pipe still in the ground under a paved front garden.
Leak detection in Highgate
N6Period houses on a steep hill, where a leak higher up the structure surfaces well below where it started.
