  • Penetrating Damp

  • Condensation

  • Rising Damp


In the following paragraphs, we'll take a look at what triggers such damp problems, and how you can set about fixing them, and stopping them from happening in the first place.


There are various exterior factors that can lead to penetrating damp in a structure, and included in these are: porous brickwork, cracked or loose roof tiles, damaged guttering or downpipes and blocked cavities. In the interior of your dwelling it can be caused by overflowing baths or sinks, damaged shower trays and leaky or burst pipework. If left unresolved, walls and woodwork can be seriously affected, and the sure indications of this will be damp, dark patches on walls, blistering or broken plaster and flaking paintwork.

If you have a leaking roof that's been neglected for some time, the timbers on your roof can be stricken with wet rot. Though it cannot spread into your brickwork, wet rot can cause your roof timbers to become structurally compromised, and in a worst case scenario you could even need to replace the whole roof - very costly! There are several warning signs of wet rot that aren't difficult to spot, the main ones being; a "spongy" feel to the timbers, a musty smell of rotten wood and the presence of black fungus on woodwork. If you detect any of these wet rot symptoms, it is imperative to address the issue swiftly to prevent further structural harm and the potential for a costly roof replacement.

The measures for prevention can be pretty basic, for instance repointing brickwork, cleaning and checking your roof & rain gutters for leaks and examining pipes for leaks. As part of an overall damp proofing package, your local Sevenoaks damp proofing company will check all these aspects.


Condensation Damp Sevenoaks UK (01732)

One of the most common reasons for dampness is condensation, and lots of properties in Sevenoaks have problems with this.

To lower the impact of this there are two steps that you can follow. You can wipe away any droplets of water as soon as they appear, and you can make certain that there's enough ventilation in areas that suffer most from condensation. This may involve the installation or updating of air bricks, extractors and cooker hoods to help remove the moist air outside of your house.

A specialist in this industry will be able to provide information, advice and solutions on this matter, because for condensation problems to be controlled, airflow and circulation within the home must be regulated effectively.

Damp Proofing Quotes in Sevenoaks Kent


A damp proof course or membrane has been installed as standard on homes built in Great Britain since 1875. It's possible that you may not have one fitted if your property in Sevenoaks was constructed before this time. It is possible that your damp proof membrane could have been damaged somehow if you are experiencing rising damp problems in a property built after this year.

It can be difficult to identify rising damp, but some giveaway indications are; tide marks on walls, white powdery deposits forming on walls or being found on floor surfaces and crumbling or rotten skirting boards. Although the existence of these is not conclusive, they are all clear indicators of rising damp problems.

Rising Damp Sevenoaks Kent

The initial step towards solving your rising damp problems should simply be to check whether or not you've actually got a damp proof course on the exterior walls of your home in Sevenoaks. For satisfactory protection it ought to be 150 millimetres (around six inches) above the level of the ground. If this is not the situation you might be able to dig away the ground to generate this gap, or if this isn't plausible, you could put in a DPM higher up.

You may have more challenging issues if you discover that your damp course is fine, and it may be that the moisture is seeping up from the ground, up through your flooring, and into your home's walls, which will be even more of a concern.

Sevenoaks damp proofing professionals will quickly be able to identify the causes of your rising damp issues, and using a range of techniques will quickly fix the problem. A damp proof cream can be injected into your walls if you have a somewhat older house with no damp proof membrane, or one that is damaged over a considerable area. Evenly spaced holes are drilled at intervals along the mortar joint, and a special nozzle is used to inject the cream, which then diffuses before curing to create an effective water-repellent barrier.

If the damp proof cream treatment is not appropriate, or the damage to your membrane is too extensive, a new damp proof course might need to be installed. Whilst this sort of repair work is a pretty drastic way to solve rising damp problems, it could be the only real solution in the final analysis.

Damp Proofers Sevenoaks (TN13)

For minimal areas of damp course damage, yet another potential solution would be to coat with a bitumen based, waterproof latex emulsion paint. This is applied underneath your current floor coverings, so carpeting, wooden flooring and tiles will have to be lifted prior to work being undertaken. This is especially efficacious in cellar areas as part of the tanking procedure to create a watertight room. Your Sevenoaks damp proof technician may suggest applying building paper (a special foil backed membrane) before the bitumen coating has completely dried out, further protection in those troublesome areas.

Tanking: "Tanking" is a method designed to make basements or other sub-ground areas water-resistant, involving the application of special watertight paint onto exposed areas. The removal of all plaster and wall coverings is essential for successful application, as the coating needs to be applied directly to the base of the walls and floors, creating a vital barrier against moisture. It's crucial to let the coating dry fully before starting any replastering or decorative work. Since tanking requires treatment of an entire property's lower level, seeking advice from multiple damp proofing experts is essential to decide if it's the best solution for your damp issues. It's important to consider less invasive alternatives that might be equally effective, given the extensive nature of tanking.


To help ease problems with condensation, you could try using dehumidifiers, which for removing moisture from the air, are pretty efficient. The fact that these gadgets merely cover up the cause of the damp and don't get rid of it, is the drawback with dehumidifier use. If you're suffering with damp or mould in any part of your home in Sevenoaks, you can get in touch with a certified damp proofing company for the most reliable advice.


The most reliable recommendations for professionals when it comes to home improvements are usually friends and family.

Woodworm Treatment in Sevenoaks

Woodworm infestations are not at all uncommon in Sevenoaks, particularly in properties that are older where the larvae of certain types of beetles feast on the timber. This can cause serious damage over time, making the structure unsound and unsafe. Woodworm treatment is crucial to prevent any serious harm to the building.

To combat woodworm, the first step is to pinpoint the particular kind of beetle that's doing the damage. As each kind of beetle necessitates a unique treatment approach, it's important to engage a woodworm specialist who can perform a thorough evaluation of the situation and prescribe the most appropriate course of action. Only with a precise diagnosis and expert guidance can one successfully combat a woodworm infestation.

Insecticides are the most common technique for treating woodworm, and can be applied in gel or liquid form. These treatments seep into the timber and exterminate the larvae. For more severe infestations, fumigation could be necessary. The fumigation process involves sealing-off the area in question and discharging a gas into the space to eliminate the larvae.

Preventing woodworm infestations in the future requires creating an environment that isn't favourable for their growth. This can be accomplished through correct management of the surroundings, including ensuring good ventilation, regulating humidity levels, and addressing any current woodworm infestations as soon as they are detected. By adopting these proactive measures, one can effectively mitigate the risk of woodworm damage and the associated costs.

Frequent inspections of the building can also help identify any woodworm infestations early, allowing for prompt treatment to minimise damage. It's also important to address any water damage, since damp wood attracts woodworm.

In conclusion, woodworm treatment and prevention require a proactive approach, with regular inspections and speedy treatment of any infestations. With the help of a professional Sevenoaks woodworm specialist and implementing prevention measures, homeowners can protect their buildings and preserve their structural integrity.

Positive Input Ventilation (PIV)

PIV (Positive Input Ventilation) might be the ideal solution for eliminating issues with damp in your house in Sevenoaks. PIV can help in reducing humidity, which can alleviate mould and damp in your home, or condensation on your windows. Achieving this is accomplished by the constant supply of fresh air. The continual replacement and refresh of air inside your property has been shown to reduce pollutants and odours, decrease dust mite allergens, and improve air quality, ultimately benefiting asthma and allergy sufferers in their day-to-day lives. For optimal performance, PIV systems should be installed in a loft, and it is important to ensure that your house is reasonably airtight when considering this option. When gaps exist around doors or windows, fresh air can escape while polluted air enters, since air follows the path of least resistance, similar to water.

DPC Replacement Sevenoaks

Preserving the structural integrity and visual appeal of your Sevenoaks property necessitates the timely replacement of a deteriorating Damp Proof Course (DPC). As time elapses, the existing DPC may become compromised, potentially leading to the emergence of rising damp. Vigilant observation for signs like crumbling plaster, damp patches or deteriorating brickwork is essential. DPC replacement involves removing the old, ineffective barrier and installing a new, sturdy one. This process typically demands professional expertise, as it necessitates meticulousness and precision to guarantee a dependable barrier against moisture infiltration.

The choice of materials for the new DPC can encompass a spectrum of options, from traditional approaches like bitumen or slate to more modern solutions such as chemical injections. A successful DPC replacement not only prevents further moisture-induced damage but also helps maintain a healthy indoor environment and protects the value of your Sevenoaks property. Frequent inspections and timely DPC replacement can substantially contribute to ensuring your home remains dry and structurally sound. (55779 DPC Replacement Sevenoaks)
