Leak to dry to treated, one company in Southall

Southall's housing runs from Victorian and Edwardian terraces around Southall Green to 1930s semis, post-war estates such as Dormers Wells, and flats above shops on the Broadway and South Road. Many terraces have been extended and subdivided into multi-occupancy homes, adding extra bathrooms, kitchens and pipework that ageing drainage and flat-roof extensions were never designed to carry, so hidden leaks are common.

Common leaks in Southall homes

Flat-roofed rear extensions

Southall's terraced houses commonly have rear kitchen or bathroom extensions with flat roofs, added decades ago to create extra living space. Felt or asphalt coverings perish over time, and once the waterproofing fails, water tracks along joists and ceilings unnoticed for months, staining plaster and rotting timber long before a damp patch becomes visible indoors.

Multi-occupancy plumbing under pressure

Many Southall terraces house extended families or multiple tenants, with extra bathrooms and kitchens added to serve them. This increases the number of joints, seals and pipe runs hidden behind walls and under floors, so a single perished washer or loose fitting can leak steadily for weeks, soaking joists and subfloors before anyone notices.

Flats above Broadway and South Road shops

The residential flats sitting above shops along Southall Broadway and South Road rely on shared roofs and communal plumbing risers serving the units below. When a roof membrane splits or a riser joint fails, water can run down through several floors, soaking shop stock and ceilings before the source is ever traced.

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.

Clearly communication, easy to deal with and responsive. We would thoroughly recommend. The report was really detailed making our buying negotiations a lot stronger and leaving us with a clear plan of action with possible timeframes.

Was lovely working with the team and they did a fantastic and quick job to get all the mould out of my bathroom. Very much looking forward to working with them on other projects around my house!! Thank you for everything and shout out to Karim for being so sweet!

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.
