Damp, mould & leak services in Hammersmith

Hammersmith's housing spans Georgian and Victorian riverside terraces along Upper and Lower Mall, dense Victorian terraces and split conversions around Brackenbury Village and Ravenscourt Park, 1930s mansion blocks near Brook Green, and post-war estates and modern flats around King Street and Hammersmith Broadway. This mix of solid-walled Victorian stock, ageing communal plumbing and river-adjacent foundations creates varied but persistent damp, mould and leak problems throughout the borough.

Common damp problems in Hammersmith homes

Riverside terraces and Thames flood risk

Georgian and Victorian houses along Upper Mall, Lower Mall and Hammersmith Terrace sit close to the Thames, with solid brick walls and shallow foundations prone to rising damp and groundwater ingress, especially after high tides or heavy rain. Original single-glazed sash windows also trap condensation between panes and along reveals, encouraging black mould on surrounding plasterwork in these older riverside properties.

Converted Victorian terraces and poor ventilation

Many Victorian terraces in Brackenbury Village and Ravenscourt Park have been split into flats, often losing original chimneys and through-ventilation in the process. Bathrooms and kitchens fitted into former box rooms frequently lack adequate extraction, leading to condensation damp and mould on north-facing walls. Parapet gutters and Victorian roof valleys, common on these terraces, are also a recurring source of penetrating damp when poorly maintained.

Mansion blocks and estates near King Street and Hammersmith Broadway

The 1930s mansion blocks around Brook Green and the post-war estates near King Street and Hammersmith Broadway rely on shared flat roofs, communal downpipes and ageing internal plumbing risers. Leaks from a neighbouring flat or a failed roof membrane can travel through party walls and floors before surfacing, while concrete and steel-framed blocks are prone to interstitial condensation and mould around cold bridges at window and balcony junctions.

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.
