Damp, mould & leak services in Brentford

Brentford's housing stock spans Victorian and Edwardian terraces around Ealing Road and Clayponds, 1930s semis near Boston Manor and Syon Lane, and a wave of riverside and canalside conversions and new-build flats at Brentford Dock, Brentford Lock and Waterside. This mix of solid-walled older brick, converted wharves and dense modern apartments sitting close to the Thames, Grand Union Canal and River Brent leaves many properties exposed to rising damp, penetrating damp and condensation.

Common damp problems in Brentford homes

Rising and penetrating damp in Victorian terraces

The solid brick terraces around Ealing Road, Half Acre and Clayponds mostly predate cavity wall construction, so many rely on old or failed damp-proof courses. Combined with original single-glazed sash windows and aging pointing, these homes are prone to rising damp at skirting level and penetrating damp through walls after heavy rain, often worsened by raised external ground levels and poorly maintained guttering.

Condensation and mould in riverside conversions and new flats

Converted warehouse flats at Brentford Dock and newer apartment blocks along Brentford Lock and Waterside are built tightly for insulation but often have inadequate trickle ventilation or extractor provision. Cooking, drying laundry indoors and bathroom steam build up moisture with nowhere to escape, leading to black mould around windows, in corner reveals and behind wardrobes placed against external walls.

Flat roof and flood-related leaks near the canal and Brent

Properties close to the Grand Union Canal, Brentford Dock marina and the River Brent, along with 1930s semis around Boston Manor and Syon Lane that have gained flat-roofed rear extensions, face two linked risks: flat roofing membranes degrading and letting water track into ceilings, and low-lying ground raising the chance of water ingress at floor level during periods of heavy or prolonged rainfall.

★★★★★

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 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.
