Damp, mould & leak services in Oval

Oval's housing stock is a mix of Victorian and Edwardian terraces converted into flats, purpose-built mansion blocks near the cricket ground, and post-war and modern developments towards Vauxhall and Nine Elms. Many terraces have been split into multiple flats sharing original pipework and roofs, while older conversions often retain ageing bathrooms and flat roof extensions, all of which raise the risk of hidden water damage.

Common leaks in Oval homes

Converted terraces and shared pipework

Many Victorian and Edwardian houses around Oval were divided into flats decades ago, leaving plumbing runs, stacks and joints serving several households through boxed-in voids. A failed joint or corroded pipe between floors can leak for weeks unnoticed, tracking along joists and emerging as staining on a ceiling far from the actual source, making leak detection essential before repairs begin.

Flat roof extensions to rear closets and bathrooms

Rear additions housing bathrooms and kitchens are common across Oval's terraced streets, many finished with felt or asphalt flat roofs installed years ago. Perished membranes, cracked upstands and blocked outlets let rainwater penetrate slowly, saturating insulation and timber above ceilings below. Damage often stays hidden until plasterboard sags or mould appears, by which time the roof covering has been failing for some time.

Upper-floor bathrooms leaking into flats below

In blocks and converted houses around Kennington Park and Stockwell borders, bathrooms sit directly above neighbouring flats rather than gardens. Perished shower seals, cracked tray joints or failed waste connections allow water to seep through the floor structure, affecting the ceiling and walls of the property below. Because the leak source is upstairs, tracing it accurately requires proper detection rather than guesswork.

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.
