Understanding Rising Damp and What Causes It
Rising damp is caused when moisture from the ground is drawn up into the walls of a property through capillary action. This usually happens when there’s no proper damp-proof course (DPC) in place or when an existing one has become damaged or bridged over time. Properties built before the 1950s are especially vulnerable, as many were constructed without a DPC or with materials that don’t provide a strong barrier against moisture. When rising damp occurs, it typically appears as tide marks or staining on interior walls, flaking paint, crumbling plaster, and even a musty smell. These visible signs are often just the beginning, as the real damage can affect the structure of your walls and timber work if left untreated. In Bromley, where many homes fall into the older category, it’s important to catch the problem early and seek professional damp proofing help before it spreads.

Common Signs of Rising Damp in Bromley Homes
Spotting rising damp early is key to stopping it from becoming a more serious and expensive issue. In most Bromley homes, the first sign is damp patches or discolouration at the base of internal walls. These marks tend to rise no more than one metre above ground level and are often accompanied by salt deposits. You may also notice paint bubbling, wallpaper peeling, or plaster becoming soft and crumbly. Skirting boards can also warp, decay, or come loose as the dampness creeps upwards. In more severe cases, a musty odour will linger in the room, and black mould may start to form, particularly in corners and near the floor. Because rising damp can often be mistaken for condensation or other forms of damp, it’s important to get a professional inspection. Apollo Damp Proofing provides detailed assessments across Bromley, so we can identify the cause and put the right treatment plan in place.

How We Treat Rising Damp in Bromley
At Apollo Damp Proofing, we specialise in rising damp treatments tailored to each property’s unique condition. Our first step is to carry out a full survey to confirm that the damp is coming from the ground up and not due to leaking pipes, poor ventilation, or other causes. Once diagnosed, our usual treatment involves installing a new chemical damp-proof course. This is injected directly into the walls to form a barrier that stops moisture from rising. In some cases, we also need to remove and replace old plaster that has been damaged by salts and moisture. Once treated, walls are left to dry thoroughly before any decorative work is completed. Our process is efficient and causes minimal disruption to your home. We also give expert advice on how to prevent the problem from returning, whether it’s improving ventilation or checking for exterior defects that could be contributing to damp conditions. All work comes with long-term guarantees to give you peace of mind.

Frequently Asked Questions
Rising damp can be tricky to identify because it shares symptoms with other forms of damp, such as condensation and penetrating damp. However, there are some tell-tale signs. If the damp patches are limited to the lower part of your walls — usually no more than a metre above floor level — and you see a tide mark, staining, or salt deposits, rising damp is likely the cause. The plaster might be crumbling, and skirting boards may be decaying or coming loose. In contrast, condensation tends to form on cold surfaces like windows or high corners, and penetrating damp usually appears due to issues like leaking gutters or cracks in external walls. At Apollo Damp Proofing, we always recommend a professional damp survey to determine the exact cause. Correct diagnosis is essential, as the wrong treatment could lead to wasted time, money, and even further damage to your home.
Yes, rising damp can contribute to health issues if left unresolved, especially in poorly ventilated properties. While the damp itself isn’t toxic, it creates the perfect environment for mould to thrive. This mould can release spores into the air that may trigger allergic reactions or worsen respiratory conditions such as asthma or bronchitis. People with weakened immune systems, the elderly, and young children are particularly vulnerable. In some cases, constant exposure to mould spores can cause persistent coughing, throat irritation, or even skin rashes. The musty smell that often accompanies rising damp is also unpleasant and can linger in soft furnishings like curtains or carpets. Beyond health concerns, damp conditions can lower the comfort of your home and increase heating bills, as moisture-laden walls make it harder to keep your house warm. Dealing with rising damp promptly will not only protect your property but also support a healthier living environment for everyone inside.
The time it takes to treat rising damp will depend on the extent of the problem and the size of the affected area. For an average-sized room in a typical Bromley home, the damp-proofing treatment itself can usually be completed within a few days. This includes installing a new damp-proof course and removing any damaged plaster. However, after treatment, it’s important to allow the walls to fully dry out before redecorating. This drying process can take several weeks, depending on the materials used and the severity of the moisture. As for disruption, we understand that having work done in your home can be stressful, so we always aim to keep noise, mess, and downtime to a minimum. At Apollo Damp Proofing, we cover furniture and flooring, clean up thoroughly each day, and communicate clearly about what to expect. Most of our clients are pleasantly surprised by how smooth and straightforward the process is.
Whether rising damp is covered by your home insurance policy depends on the specific terms and conditions of your insurer. In many cases, standard home insurance does not cover rising damp because it is considered a maintenance issue rather than an unexpected event. Insurers typically expect homeowners to carry out regular checks and upkeep to prevent such problems from developing. However, if the rising damp is caused by a sudden fault, such as a burst pipe or structural defect, you might be eligible for cover under accidental damage or building protection. We recommend checking your policy documents carefully and speaking directly with your insurer. At Apollo Damp Proofing, we can provide written reports, survey documentation, and photographs to support any insurance claim you may make. Even if it’s not covered, we’ll work with you to find a cost-effective treatment plan that ensures your property is protected long-term.
