Leak to dry to treated, one company in Holborn

Holborn's housing stock combines Victorian mansion blocks, Georgian terraces near Lincoln's Inn Fields and Red Lion Square, and converted office buildings turned into flats above ground-floor shops. This mix of ageing plumbing, flat-roofed extensions and shared risers means hidden leaks often travel between commercial and residential floors before anyone notices.

Common leaks in Holborn homes

Ageing risers in Victorian mansion blocks

Many of Holborn's Victorian and Edwardian mansion blocks around Bloomsbury and Red Lion Square still rely on original cast iron or early lead plumbing risers shared between flats. When joints corrode or seals perish, water tracks silently down internal walls and between floors, often surfacing as damp patches or ceiling staining several flats away from the actual source, making leak detection essential before extensive damage occurs.

Flat roofs on converted office buildings

Holborn has seen many former legal and commercial office buildings near Chancery Lane and Kingsway converted into residential flats, frequently featuring flat roofs and rear extensions. These roofs age faster than pitched alternatives, and perished felt or cracked seals allow rainwater to seep in gradually, causing hidden leaks that soak insulation and timber long before any staining appears on ceilings below.

Bathrooms leaking into commercial units below

Many Holborn buildings mix ground-floor shops or offices with flats above, particularly around Fleet Street and Hatton Garden. When bathroom seals, shower trays or waste pipes fail in upper flats, water can escape unnoticed and travel down into the commercial premises beneath, causing stock damage and disputes over responsibility unless the source is traced quickly and accurately.

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.
