Common Damp Problems in Hammersmith
Penetrating damp in mansion block properties is the most common issue we encounter in W6, often entering through failed parapet copings, blocked box gutters or poorly maintained flat roof sections above top-floor flats. Period conversions (particularly those where Victorian houses have been divided into flats) frequently present issues where shared roof drainage has been neglected. Flat roof leaks in 1960s and 1970s residential buildings are another regular callout, and we also attend Hammersmith riverside developments for balcony and terrace waterproofing failures.
Urgent cases are prioritised when water is coming through a ceiling or a pipe has burst.

Frequently asked questions: Hammersmith
Do you handle emergencies?
Yes. Burst pipes, active water ingress and severe mould situations that pose a health risk are prioritised. Call 0800 054 1524 and explain the urgency. Out-of-hours enquiries can be sent via WhatsApp at any time.
How do I know if my property has rising damp?
Rising damp typically presents as tide marks on lower walls, white salt deposits (efflorescence) near skirting level, peeling or bubbling wallpaper and plaster, and a distinctive musty smell. In older properties without modern damp proof courses, rising damp is common. A calibrated moisture meter survey confirms whether what you’re seeing is genuine rising damp or another form of moisture problem.
Can damp cause health problems?
Yes. Damp conditions encourage mould growth, which produces spores and mycotoxins that can cause or worsen respiratory conditions, allergic reactions, and in vulnerable people (children, elderly, and those with asthma or immune conditions) more serious health effects. Black mould (Stachybotrys) is particularly problematic. Professional treatment addresses both the mould and the underlying damp that feeds it.
Do you work with letting agents and property managers?
Yes. We work regularly with letting agents and property management companies across our coverage area. We offer priority attendance for managed portfolios, reports suitable as supporting evidence for housing, landlord or compliance matters, and standardised PDF reports that integrate with property management systems. We can liaise directly with tenants or landlords as required.
What happens if mould keeps coming back after treatment?
Recurring mould indicates the underlying damp cause has not been fully resolved. Mould treated without addressing the root cause (whether condensation, rising damp, a structural leak, or a plumbing issue) will return within weeks or months. Our surveys identify the root cause and our treatment includes addressing it, not just treating the surface symptom.
Water Infrastructure in Hammersmith Services
Hammersmith Services is served by Thames Water for both water supply and sewerage. When Thames Water mains pipes fail (particularly the Victorian-era cast iron infrastructure common across South and East London), the resulting ground saturation can cause significant water ingress into nearby properties. If you have experienced unexplained damp following a Thames Water mains burst or repair in your area, our independent investigation reports establish the connection between the infrastructure event and damage to your property, supporting both Thames Water claims and buildings insurance claims.
