Leak to dry to treated, one company in Bloomsbury

Bloomsbury's housing stock ranges from Georgian townhouses and grand garden squares to Victorian terraces, mansion blocks and postwar university halls converted into flats. Many buildings have been subdivided into multiple flats over decades, meaning old plumbing risers, shared bathrooms and flat roofs sit above communal hallways and neighbouring properties, so a single hidden leak can quickly affect several households.

Areas of Bloomsbury we cover

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

Common leaks in Bloomsbury homes

Georgian townhouses split into flats

Many Bloomsbury townhouses around the garden squares were carved into flats generations ago, leaving plumbing runs buried behind later stud walls and under stairwells. Failed joints or perished pipe seals inside these hidden voids can leak for weeks, tracking down through old lath and plaster ceilings into the flat below before any staining becomes visible, by which point timber joists and skirting may already be affected.

Mansion block bathrooms leaking downward

The mansion blocks and converted terraces near Russell Square and the Brunswick Centre stack bathrooms directly above neighbouring flats, sharing waste pipes and floor voids. A cracked shower tray, failed sealant around a bath, or a slow leak from a WC connection can seep through the concrete or timber floor structure, appearing as a ceiling stain or bulge in the flat below long after the leak began.

Flat roofs on converted and institutional buildings

Bloomsbury has numerous flat-roofed extensions, mansard conversions and former institutional buildings now used as offices or student accommodation. Ageing felt or asphalt coverings, perished flashing around chimneys and parapets, and blocked outlets allow water to enter gradually rather than pour in, so it can travel sideways across ceiling voids before dripping through plasterwork some distance from the actual point of entry.

What our customers say

★★★★★

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.

I have been dealing with damp and mould for years but these guys were able to come in and resolve the problem quickly and professionally. Their prices were fair and reasonable and they got the job done clean. 10/10 would use again and would recommend.

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.
