Common Damp Problems in Notting Hill
Basement damp is by far the most prevalent issue we encounter in W11, both penetrating damp through the below-ground external walls and floor slabs, and rising damp in garden-level lower-ground-floor rooms. Condensation and mould in basement flats is also extremely common, as these spaces typically have restricted ventilation and lower temperatures. Penetrating damp in the period stucco frontages is another frequent finding: the render cracks as it ages, allowing water to saturate the brickwork behind. We also attend Notting Hill properties for roof and parapet leaks in the large Victorian mansion blocks.
Urgent cases are prioritised when water is coming through a ceiling or a pipe has burst.

2
Moisture readings
Calibrated moisture meter readings across walls, floors and ceilings.
3
Thermal imaging
Infrared scanning, where suitable, to reveal hidden moisture and cold spots behind finishes.
4
Acoustic & tracer gas
Acoustic listening and tracer gas, where suitable, to pinpoint concealed pipe leaks.
5
Pressure testing
Pressure testing of heating and supply pipework where suitable.
6
Photos & written report

Frequently asked questions: Notting Hill
How long does a damp survey take?
A standard residential damp survey takes 1 to 2 hours depending on property size. We check all accessible areas including loft space (if safe and accessible), subfloor (if there is a suspended floor), external walls, internal walls, and roof. The written report with moisture readings follows the visit; ask about report timing when you book.
Is black mould dangerous?
Black mould (particularly Stachybotrys chartarum) produces mycotoxins that are harmful to health, especially in children, elderly people, and those with respiratory conditions. Even common mould species (Aspergillus, Penicillium, Cladosporium) found in damp UK properties can cause allergic reactions and respiratory problems. Professional treatment and resolution of the underlying damp cause is strongly recommended.
What are the signs of a hidden water leak?
Signs of a hidden leak include: unexplained wet patches on walls or ceilings with no obvious source, water meter turning when all taps are off, low water pressure, musty smells in rooms with no visible damp, and damp patches that appear and disappear. Acoustic and thermal imaging leak detection can locate hidden leaks without unnecessary damage.
Can you treat mould without a survey first?
We recommend a survey before treatment in most cases, particularly for severe or recurring mould, or where the cause is not clearly condensation. Treating mould without identifying the cause risks the mould returning quickly. For straightforward condensation mould in well-ventilated rooms, a survey may not always be necessary. Call us and we will advise based on your specific situation.
Do you put your findings and any remedial work in writing?
Our investigation report sets out exactly what treatment is needed and why. Any remedial works you then commission, through our team or a contractor of your choice, are quoted and confirmed in writing before they start.
Water Infrastructure in Notting Hill Services
Notting Hill 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.
