Hammersmith's Housing Stock Is Particularly Vulnerable to Damp
Hammersmith has one of West London's most varied housing stocks — large Georgian terraces and Victorian villas sit alongside converted Edwardian mansion flats, modern riverside apartments, and the period terraces of Brook Green and Ravenscourt Park. Despite this variety, damp is extremely common across W6 and W14, driven primarily by the area's Thames frontage and dense stock of period conversions.
Hammersmith's position directly on the Thames is the dominant damp risk factor. The river creates high groundwater levels throughout the borough — particularly in lower-lying streets near the Embankment, along Crabtree Lane, and in the riverside developments between Hammersmith Bridge and Chiswick. Properties close to the river regularly experience lateral groundwater ingress that requires specialist structural waterproofing.
Inland from the river, the Victorian and Edwardian terraces of Brook Green, Ravenscourt Park, and the streets around King Street regularly present with rising damp and penetrating damp through deteriorating brickwork and failed pointing. The large number of converted flats throughout W6 also generates significant condensation problems, particularly in lower-floor apartments with limited ventilation.
The Federation of Damp connects Hammersmith homeowners with certified damp specialists who diagnose accurately and carry out work to our vetting and accreditation standards.
What starts as a tide mark and some flaking plaster can, over months, develop into significant structural damage, timber rot and mould growth affecting air quality. The longer it is left, the more expensive it becomes to treat properly.
Types of Damp We Treat in Hammersmith SW18
Our certified specialists diagnose and treat all forms of damp affecting residential and commercial properties across SW18 and surrounding postcodes.
Rising Damp
Moisture travelling upward through masonry where the damp proof course has failed or been bridged. Visible as tide marks and crumbling plaster at skirting level — extremely common in Hammersmith's Victorian and Edwardian terraces — particularly on streets around Brook Green, Ravenscourt Park, and the period properties between Hammersmith and Shepherd's Bush.
Penetrating Damp
Water entering horizontally through failed pointing, defective render or damaged guttering. Requires external defect identification and repair before any internal treatment can be effective. Common in Hammersmith's Victorian and Edwardian terraces where failed pointing and deteriorating render allows water ingress. Particularly prevalent in the denser streets around King Street, Glenthorne Road, and the period properties of Brook Green.
Condensation & Mould
The most common form in converted flats and modern properties. Often misdiagnosed as rising damp. Requires a proper ventilation assessment — not just surface mould treatment or anti-mould paint. Very common in Hammersmith's large stock of converted Victorian and Edwardian flats — particularly in lower-floor apartments throughout W6 and W14. Often misdiagnosed as rising damp when the root cause is poor ventilation. Hammersmith's riverside location also increases ambient humidity year-round.
Basement & Below-Ground Damp
Hammersmith's Thames frontage creates persistently high groundwater levels. Properties near the river — particularly along Crabtree Lane, Chancellors Road, and the riverside streets between Hammersmith Bridge and Chiswick — are particularly vulnerable to lateral groundwater ingress below ground. Structural waterproofing is required — standard damp proofing is not sufficient. Request a certified specialist for an accurate assessment.

Trusted by SW18 Property Owners
"Had recurring damp on our ground floor in South Hammersmith that two companies had failed to fix. The FOD specialist identified the DPC had been bridged by raised paving — a completely different issue from what we'd been treated for. Fixed properly first time."
"Buying a riverside apartment near Hammersmith Bridge and the survey flagged lateral damp in the lower floor. The FOD specialist confirmed Thames groundwater ingress and provided a clear structural waterproofing plan with written guarantee before we exchanged."
"Quoted £6,500 for rising damp by a national firm. The FOD specialist correctly identified condensation from poor ventilation in our East Sheen conversion — sorted for under £800. Independent diagnosis made all the difference."
