Leak to dry to treated, one company in Mottingham

Mottingham is dominated by 1930s LCC cottage estate semis and terraces, built with hipped slate or tile roofs, bay windows and rear valley gutters, alongside pockets of post-war infill and low-rise flats near Mottingham Lane. This ageing interwar stock, often extended with flat-roofed kitchens and bathrooms, means original plumbing runs, valley gutters and roof coverings are now well past their intended lifespan and prone to hidden failure.

Common leaks in Mottingham homes

Valley gutters and hipped roofs on 1930s semis

Many Mottingham semis have hipped roofs with internal valley gutters that quietly deteriorate with age, allowing rainwater to seep into loft timbers and ceilings unnoticed for months. Because the leak point is often metres from where the stain appears on a bedroom ceiling, homeowners frequently miss the source until timber rot or a ceiling collapse forces an inspection.

Flat-roofed rear extensions

Kitchen and bathroom extensions added to Mottingham's cottage estate homes from the 1960s onwards typically carry felt or asphalt flat roofs. Perished membranes and blocked outlets let water track along joists before showing as damp patches on internal walls below, meaning the visible damage is rarely directly under the actual point of failure.

Retrofitted bathrooms leaking to rooms below

Original 1930s houses in Mottingham were built with a single bathroom, later supplemented by en-suites or converted box rooms with modern shower trays and sealant. Perished seals around trays, baths and waste pipes let water escape into floor joists, surfacing as staining or a sagging ceiling in the reception room or hallway underneath.

What our customers say

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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.
