Damp Proofing Services For Your Property in
Ealing
Groundwater soaking up into your walls ruins wallpaper, spoils plaster, and leaves musty smells.
Black Mould
Black mould causes toxic fungal growth on surfaces, causing breathing problems and allergic reactions.
Trapped steam from cooking and showering causes condensation on and around windows.
Moisture can lead to wet rot, dry rot and woodworm infestations, putting your property’s structural timber at risk.
Effective waterproofing protects your property from water ingress, damp, mould and costly structural damage.
What Causes Damp?
If you are experiencing damp or mould in your Ealing home or office, it almost always comes down to water finding its way in where it shouldn’t. There’s rarely a single cause, it’s often a combination of small issues that build up over time. The most common culprits we see include:
The most common culprits we see include:
- Guttering or downpipes that are cracked, blocked, or missing altogether
- Roof damage, including cracked tiles or slipped and missing tiles
- Leaking or poorly sealed water pipes, often hidden behind walls or under floors
- Inadequate ventilation, which allows moisture to build up rather than escape
- Drainage that isn’t working as it should, letting water sit against the building rather than draining away
This type of damp, known as penetrating damp, doesn’t discriminate. It can affect a Victorian terrace just as easily as a new build, since it’s caused by a fault or weakness in the building’s structure rather than its age.
What Happens if Damp is Left Untreated?
Left untreated, damp rarely stays contained to one small patch. Over time it can lead to:
- Structural damage as damp timber weakens, plaster crumbles, and brickwork deteriorates
- Mould growth, which can spread across walls and ceilings and become a health concern, particularly for anyone with asthma or respiratory issues
- Rot in timber, including skirting boards, floor joists, and window frames, which can be costly to replace once it’s taken hold
- A drop in property value, as unresolved damp is a red flag for buyers and surveyors alike
- Rising repair costs, since the longer damp is left, the more of the building it tends to affect
Catching it early and dealing with the cause, rather than just the symptoms, is generally far cheaper and less disruptive than waiting until the damage is done.
Types of Damp
Not all damp is the same, and the treatment needed depends entirely on which type you’re dealing with. Here are the three most common forms we come across:
Rising Damp
Rising damp occurs when moisture from the ground is drawn up through a wall or floor, usually because the damp-proof course (DPC) is damaged, has broken down over time, or was never installed correctly in the first place. It’s most commonly seen in older properties, typically affecting the lower sections of walls, and often visible as a tide-like staining mark a foot or so above skirting board height, along with crumbling plaster and salt deposits on the surface.
Penetrating Damp
Penetrating damp happens when water gets into a building horizontally, through a fault in the structure, such as damaged brickwork, cracked render, faulty guttering, or missing roof tiles. Unlike rising damp, it isn’t limited to ground-floor walls and can appear anywhere water is able to force its way in, including upper floors and ceilings. It tends to get worse after heavy rain and often shows up as damp patches that darken and spread during wet weather.
Condensation
Condensation forms when warm, moist air inside a building meets a cold surface, such as a window, wall, or ceiling, causing water droplets to form. It’s especially common in bathrooms, kitchens, and poorly ventilated bedrooms, and tends to worsen in colder months when windows stay shut and heating patterns change. Left unchecked, condensation is one of the most common triggers for black mould growth.
As these three types have different causes, they need different solutions. A damp-proof course repair won’t help with a ventilation problem, and improving airflow won’t fix a leaking roof. That’s why an accurate diagnosis matters more than jumping straight to a treatment.

Damp Proofing Services FAQs
How do I know if my Ealing property needs damp proofing?
The signs of rising damp can include peeling paint, damaged plaster, tide marks, salt deposits and decaying skirting boards. These symptoms can also be associated with penetrating damp or condensation, which is why a professional damp survey is recommended before any treatment is carried out. Identifying the source of moisture allows the correct remedial solution to be recommended.
What does a damp proofing survey involve?
A damp survey involves inspecting the property to determine how moisture is entering or moving through the building. This includes assessing walls, existing damp proof courses, external ground levels, brickwork and other factors that could be contributing to damp. Following the inspection, you’ll receive clear recommendations based on the condition of the property.
I am a tenant, is arranging damp proofing services my responsibility?
Your landlord is responsible for any mould caused by structural faults, disrepair, or building damage. The tenant is only responsible if the mould results directly from their own lifestyle habits, like failing to heat the home or ventilate rooms properly.
What is a damp proof course (DPC)?
A damp proof course is a barrier installed within a wall to prevent ground moisture from rising through masonry. Older properties may have an original damp proof course that has deteriorated over time, while some buildings may require a new chemical damp proof course as part of a remedial treatment where rising damp has been confirmed.
How long does damp proofing last?
When installed correctly and used to treat the appropriate form of damp, a damp proof course is designed to provide long-term protection. The lifespan of any treatment will also depend on the condition of the building and addressing any related defects that may be contributing to moisture problems.
Can you carry out damp proofing in Victorian and Edwardian homes?
Yes. Dampstar regularly works on Victorian, Edwardian and other period properties across Ealing. These buildings often require a considered & specialised approach due to their traditional construction methods, original brickwork and historic features, ensuring which damp treatment is appropriate for the property.
