Damp, mould & leak services in Soho

Soho's housing stock is dominated by Georgian and Victorian terraced buildings, many converted from commercial use into flats and apartments over recent decades. These narrow, multi-storey properties with shared party walls, ageing brickwork and original timber frames are particularly susceptible to penetrating damp, condensation and hidden plumbing failures, especially where conversions were carried out without adequate waterproofing or ventilation upgrades.

Leak Detection

Trace hidden water leaks without damage using thermal, acoustic and tracer-gas methods. Leak detection →

Damp Investigation

Identify rising damp, penetrating damp and condensation, and tell them apart properly. Damp investigation →

Mould Inspection

Find the moisture source feeding the mould, not just treat the surface. Mould inspection →

Structural Drying

Dry out walls, floors and voids after a leak or flood, monitored to completion. Structural drying →

Common damp problems in Soho homes

Penetrating Damp in Converted Georgian Terraces

Many of Soho's Georgian terraces were originally built as townhouses and later subdivided into residential flats. The original solid brick walls, now frequently repointed with hard cement mortar that traps moisture rather than allowing it to breathe, allow rainwater to penetrate deep into the fabric. Ground and first floor flats are especially vulnerable, with persistent damp patches appearing on internal walls after periods of heavy rainfall.

Condensation and Mould in Basement Conversions

Soho has a notable number of basement flats, many converted from former storage or commercial spaces beneath Victorian commercial premises. These below-ground units suffer from poor natural ventilation, limited sunlight and cold external walls, creating ideal conditions for condensation to form and black mould to develop on walls, ceilings and around window reveals, particularly during the cooler autumn and winter months.

Hidden Leaks from Ageing Shared Plumbing Stacks

Older Soho buildings converted into multiple flats frequently share original cast iron or early copper plumbing stacks that run through party walls and floor voids. Over time, joints corrode and seals fail, causing slow leaks that soak into floor joists and plaster without any obvious visible sign. These hidden leaks are often only identified when significant structural timber damage or widespread damp staining has already occurred.

Tip: If a damp patch keeps coming back after redecorating, it is almost always a symptom, not the problem. A survey that finds the source first saves paying for the same repair twice.
