To understand what the probable causes of such damp problems are, and how to go about solving them, keep on reading...


There are various external factors that can cause penetrating damp in a building, and these include things like: cavity wall problems, cracked or loose roof tiles, cracks in brickwork and damaged guttering or downpipes. In the interior of your property it can be a result of overflowing bathtubs or basins, burst or leaking pipework and damaged shower trays. If left to continue leaking these factors enable water to soak into the walls and woodwork, which over time result in broken or blistering plaster, dark, damp patches on walls and flaking paintwork.

You may get wet rot in the timbers of your roof, if you have a leaky roof, and it has been neglected for a while. Although it does not spread into brickwork, wet rot can cause your roof timbers to become structurally unsound, and in the worst case scenario you might even need a new roof - very costly! There are several warning signs of wet rot which aren't difficult to spot, the main ones being; the presence of black fungus on woodwork, a musty smell and a "spongy" feel to the timber. For the sake of avoiding further structural damage and the potential need for expensive roof replacement, it is essential to address any signs of wet rot straight away.

The measures for prevention can be quite basic, for instance cleaning your roof & rain gutters and checking for leaks, repointing dodgy brickwork and inspecting pipes for leaks. As part of an overall damp proofing package, your local Lewisham damp proofing company will check out all of these areas.


Condensation Damp Lewisham UK (020)

Condensation is super easy to identify and one of the most common forms of damp in many properties in Lewisham. When warm, moist air comes into contact with a cold surface, water forms as tiny droplets. Where high humidity is present, as in bathrooms, kitchens and boiler rooms, condensation is often caused by poor ventilation.

To reduce the impact of this problem there are a couple of steps that you can follow. You can wipe away any water droplets as soon as they appear, and you can ensure that there's good ventilation in areas that suffer from condensation. Redirecting humid air to the outside of your property in Lewisham, by updating or installing extractor fans, cooker hoods and air bricks, will help you to resolve this issue.

By performing a comprehensive damp proofing survey, a reputable Lewisham company will identify any spots where damp air is drawn in from the outside, simply contributing to the condensation issue. A specialist in this industry will be able to offer information, solutions and guidance on this matter, because for condensation issues to be controlled, any airflow within the home must be correctly regulated.

Damp Proofing Quotes in Lewisham Greater London


Homes constructed since 1875 in the United Kingdom have been required to have a damp proof course or membrane to be installed as standard. You might not have a damp proof course installed on your property or home in Lewisham if it was constructed earlier than this. It's possible that your DPM might have been damaged somehow if you are experiencing rising damp issues in a house built after this date.

Although tricky to identify, rotten or crumbling skirtings, "tide marks" on walls and a white powdery deposit being found on floor surfaces or appearing on walls, are all giveaway clues that you might have rising damp. It's plausible that you may have a rising damp issue if you have spotted one or more of these in your property.

Rising Damp Lewisham Greater London

The initial step towards solving your rising damp problems should simply be to check whether or not you have in fact got a damp proof course on the exterior walls of your home in Lewisham. It ought to be 150mm above the level of the ground for adequate protection. If you discover that this space doesn't exist, you can dig the soil away to increase it, or if this approach is not feasible, a higher DPM (damp proof membrane) will have to be installed.

If this isn't the problem and your DPM (damp proof membrane) is in fact correct, there could be more serious issues to resolve caused by the moisture rising up from the ground, up through your floors, and into your walls.

Using a number of procedures, damp proofing experts in Lewisham can quickly detect and solve rising damp. Older properties which either don't have a DPM, or have a compromised one that is damaged over a wide area, can have a damp proof cream (such as Dryzone) injected into the walls. This special cream is injected with a nozzle into evenly spaced holes drilled along the mortar joint, and before the cream can set it turns to liquid and soaks into the surrounding brickwork forming a barrier that is water-repellent.

If the damp proof cream isn't sufficient, or the damage is too extensive to your DPM, a new damp proof course may have to be installed. This is taking repair work to the extreme, but it might be the only remedy for your rising damp.

Damp Proofers Lewisham (SE13)

Painting with a bitumen based, waterproof latex emulsion, is yet another potential solution for smaller areas of damp course damage. This has to be applied under your floor coverings, so tiles, carpeting and wooden flooring will have to be lifted prior to work being done. Also used as a part of the "tanking" process to create a waterproof room, this is a particularly efficacious solution in basements. Before the bitumen paint has completely dried out, your Lewisham damp proofing technician may suggest laying building paper (a specialist foil backed membrane), for additional protection.

Tanking: The waterproofing method known as "tanking" for cellars or subterranean areas involves applying a specific watertight paint on bare surfaces. Effective application requires first removing all existing plaster and wall coverings to allow the paint to adhere directly to the base of the floors and walls, forming a critical moisture barrier. After the paint is applied, it is imperative to let it dry completely before proceeding with any replastering and decorative works. Considering the extensive nature of tanking, as it involves treating an entire lower level of a property, obtaining advice from multiple damp proofing professionals is recommended to ensure it's the right solution for your damp issues. Due to the invasive nature of tanking, it's important to consider other less disruptive yet effective alternatives.


Problems with condensation can definitely be improved through the use of dehumidifiers, which are an efficient way to remove moisture from the air. The trouble with dehumidifier use in attempting to stop damp and mould is that they simply hide the cause of the damp, not get rid of it. If you are suffering from dampness in any part of your home in Lewisham, you should call on a competent damp proofing company for the most reliable advice.

Some of the Benefits of Using Dehumidifiers

Among the many advantages of employing dehumidifiers are the following:

  1. Comfort: Reducing indoor humidity levels can make the environment feel cooler and more comfortable, improving living conditions.
  2. Energy Efficiency: Some dehumidifiers contribute to the efficiency of heating systems by ensuring air is drier and thus more readily heated, which can lead to potential energy savings.
  3. Protects Structure and Belongings: Lower humidity levels contribute to the protection of the home's structural soundness by avoiding damp-related issues and also safeguard belongings from the damage moisture can cause.
  4. Reduced Odours: Creates a fresher and more delightful living environment by eliminating the musty odours that high levels of humidity cause.
  5. Health Improvements: Dehumidifiers, by controlling humidity levels, play a significant part in inhibiting the growth of allergens like mould and dust mites, which can trigger respiratory issues and amplify the effects of asthma and allergies.

Woodworm Treatment and Prevention Lewisham

Unfortunately, woodworm is a common issue that can affect properties of all ages. The larvae of certain kinds of beetles feast on timber, which can lead to significant damage over time. Nonetheless, there are a number of steps that you can take to prevent woodworm infestations and address any pre-existing problems.

The starting point of woodworm treatment is to establish the kind of woodworm that is present, as different species demand different treatment methods. This is best done by a woodworm specialist, who can also evaluate the level of the infestation and propose the most appropriate plan of action.

One effective woodworm treatment method is the use of insecticides, which can be applied in gel or liquid form. This kind of treatment is especially effective for minor infestations, but might not be suitable for more extreme cases. For larger or more severe infestations, fumigation might be necessary. This involves sealing-off the affected area and releasing a gas into the space to kill off the larvae. Fumigation is a far more invasive treatment option and requires specialist training and equipment, so it's vital to bring in a qualified professional.

Prevention is also key in avoiding future woodworm infestations. This can be achieved through regular inspections, maintaining good humidity levels and ventilation, and treating any existing woodworm as soon as it's identified.

Frequent checks of the property can aid in the timely detection of infestations of woodworm, thus mitigating harm. In addition, it is crucial to take care of any water damage as damp wood can be a magnet for woodworm. In the event that you have wooden items or furnishings in your house, it is important to keep them free from moisture and well-maintained to prevent woodworm infestations.

PIV (Positive Input Ventilation)

Positive Input Ventilation (PIV) can offer the perfect solution to reduce damp problems within your home in Lewisham. Positive Input Ventilation can aid in reducing humidity levels, which can alleviate damp and mould in your dwelling or condensation around your windows. A constant flow of fresh air is supplied to achieve this. The constant refresh and replacement of air inside your house has been shown to reduce odours and pollutants, decrease dust mite allergens, and enhance air quality, ultimately benefiting allergy and asthma sufferers in their day-to-day lives. Installing PIV systems in a roof space and ensuring that your house is reasonably airtight are important considerations when opting for this solution. Just like water, air follows the path of least resistance, and any spaces and gaps in doors or windows can let fresh air out while allowing polluted air in.

DPC Replacement Lewisham

Ensuring the structural stability and visual appearance of your property in Lewisham hinges on the timely replacement of the Damp Proof Course (DPC). Over time, the existing DPC can succumb to the forces of wear and tear, potentially leading to rising damp and its associated complications. Vigilantly monitoring for signs such as damp spots, deteriorating brickwork or crumbling plaster is paramount. DPC replacement necessitates the removal of the old, compromised barrier and the installation of a new, resilient one. This intricate process typically requires the expertise of seasoned professionals, as it hinges on precision and meticulousness to guarantee an impenetrable seal against moisture intrusion.

The choice of materials for the new Damp Proof Course can encompass a variety of options, from traditional methods like slate or bitumen to more modern solutions such as chemical injections. A successful DPC replacement not only prevents further damage caused by moisture but also helps maintain a healthy indoor environment and preserves the value of your Lewisham property. Regular inspections and timely DPC replacement can significantly contribute to ensuring your property remains structurally sound and dry. (20879 DPC Replacement Lewisham)
