Leak to dry to treated, one company in Kensington and Chelsea

Kensington and Chelsea's housing stock is dominated by grand Victorian and Edwardian terraces long ago carved into multiple flats, alongside stucco-fronted mansion blocks and mews conversions. Shared risers, communal plumbing runs and stacked bathrooms mean a single failed joint or seal can send water tracking silently through several floors before residents below notice ceiling staining.

Common leaks in Kensington and Chelsea homes

Shared pipework in converted period flats

Many Kensington and Chelsea terraces were subdivided decades ago, leaving vertical soil stacks and water pipes boxed into walls and floor voids shared by several flats. When a joint or connector on an upper floor fails, water can travel unseen along joists and service ducts, reappearing as damp patches or a stained ceiling in a completely different flat below.

Flat roofs over rear additions and mansion blocks

Rear closet wings, kitchen extensions and the flat roofs topping many mansion blocks across Chelsea and South Kensington rely on ageing felt or asphalt coverings. Once perished, cracked or poorly maintained around upstands and outlets, these roofs allow rainwater to seep gradually into the structure below, often tracking sideways before it surfaces as a ceiling stain well away from the actual defect.

Bathroom conversions and basement lower ground floors

Loft and lower ground floor conversions are common across the borough's tall terraced houses, often adding extra bathrooms directly above living rooms or basement conversions. Perished shower tray seals, cracked grout or a failed waste pipe connection can let water escape through the floor structure for weeks, causing hidden rot and staining in the room below long before it is discovered.

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.
