Leak to dry to treated, one company in Kensington

Kensington's housing stock is dominated by tall Victorian and Edwardian stucco-fronted terraces, many long ago converted into stacked flats, alongside grand mansion blocks, mews houses and increasingly deep basement extensions. This mix means shared pipework running through multiple households, ageing lead flat roofs over porticoes, and excavated lower-ground floors, all of which raise the chances of a hidden leak going unnoticed until real damage appears.

Common leaks in Kensington homes

Shared pipework in converted terraces

Many Kensington terraces were split into flats decades ago, with bathrooms and kitchens stacked above one another sharing risers and waste pipes never designed for multiple households. A failed joint or perished seal behind a wall can send water quietly into the flat below for weeks, showing up as a ceiling stain long after the original fitting has failed.

Ageing flat and mansard roofs

The porticoes, rear additions and mansard extensions common across Kensington's period properties often rely on lead or felt flat roofing that degrades gradually rather than failing all at once. Perished flashing around chimneys and roof lights lets water track along joists and down internal walls, so the damp patch inside can be metres from where the roof is actually letting in.

Basement and lower ground floor conversions

Extended basements beneath Kensington townhouses depend on tanking, sumps and pumps to stay dry, and any weakness in that system allows an escape of water from above to collect below ground rather than draining away. Because these spaces are often used as bedrooms or kitchens, a slow leak can saturate flooring and stud walls before residents notice anything beyond a musty smell.

What our customers say

Excellent
Rated 5.0 / 5 based on 20 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.
