Leak to dry to treated, one company in Fitzrovia

Fitzrovia mixes Georgian and Victorian terraces converted into flats with mansion blocks, ex-council estates and dense post-war office-to-residential conversions. Shared risers, communal roofs and stacked bathrooms in subdivided townhouses mean a single failed joint or perished seal can travel through several floors before anyone notices, often surfacing as damp patches far from the original source.

Areas of Fitzrovia we cover

We attend leaks right across Fitzrovia and its neighbourhoods, including:

Common leaks in Fitzrovia homes

Converted Georgian townhouses with stacked bathrooms

Many Fitzrovia townhouses were carved into flats decades ago, stacking bathrooms above kitchens and living rooms with plumbing runs bridged awkwardly between original and inserted structures. Waste pipes and shower trays fitted during conversion often sit on ageing joists never designed for wet rooms, so a slow leak from a failed seal or cracked trap can seep into the ceiling void below for weeks before staining appears.

Flat roofs on mansion blocks and mews conversions

Several mansion blocks and rear mews buildings around Fitzrovia carry flat or low-pitch roofs above extensions and closet wings. Ageing felt or asphalt coverings, perished flashing around parapets and blocked outlets let rainwater track sideways under the membrane, entering top-floor flats through cornices or light fittings well away from the actual breach point, making the source hard to trace without investigation.

Ageing risers in subdivided period buildings

Buildings split into multiple leaseholds share vertical risers carrying supply and waste pipework often installed mid-century and rarely inspected communally. Corroded joints, perished rubber seals and old soldered fittings hidden behind boxing can fail quietly, sending water down through party walls into neighbouring flats and creating disputes over responsibility when the leak's true origin sits behind another owner's panelling.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

Tip: If your water meter ticks over with every tap off, or a wall or ceiling stays damp with no obvious cause, there is a hidden leak. Finding it early is far cheaper than repairing the mould and damage it leaves behind.
