Damp, mould & leak services in Westminster

Westminster's housing stock ranges from Georgian and Victorian stucco-fronted terraces carved into flats to grand mansion blocks, mews conversions and high-value new-build developments. Many buildings share communal risers, roof terraces and basement conversions decades old, so a single failed joint or perished seal can travel through several floors before anyone notices, often behind period plasterwork and cornicing.

Common leaks in Westminster homes

Converted terraces with shared plumbing risers

Many Pimlico and Bayswater terraces were split into flats last century, with plumbing risers boxed in and shared between units. A failed joint or corroded pipe several floors up can travel down through party walls and ceilings, so the visible damp patch in one flat often points to a leak that started well above it.

Flat roofs on mews and rear extensions

Mews buildings and rear extensions common around Marylebone and Fitzrovia frequently have flat or low-pitch roofs with felt or asphalt coverings. Perished flashing or a split membrane lets water track along joists before it appears as a ceiling stain, meaning the entry point is rarely directly above the damage.

Bathrooms over period ceilings

Victorian mansion blocks and townhouses in Belgravia and Marylebone were rarely built with waterproof tanking beneath bathroom floors. When a shower tray seal or bath edge perishes, water seeps through original timber floors and lath-and-plaster ceilings below, staining decorative cornicing before residents realise there is a problem.

What our customers say

Excellent
Rated 5.0 / 5 based on 22 reviews on
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.
