Damp Proofing Hersham Surrey (KT12)


  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we will take a look at what triggers such damp problems, and ways that you can set about resolving them, and stopping them from occurring.


Penetrating damp can be attributable to different external factors such as: broken or loose roof tiles, defective downspouts or guttering, damaged or porous brickwork and blocked cavities. In the interior of your home it can be caused by burst or dripping pipework, damaged shower trays and overflowing sinks or baths. Woodwork and walls can be affected if left uncontrolled, and will be noticeable as broken or blistering plaster, dark, damp patches on walls and flaking or bubbling paintwork.

If you've got a leaky roof that's been left untreated for some time, the timbers on your roof can be stricken with wet rot. Although it's fortunate that wet rot doesn't have an impact on brickwork, in a worst case scenario, you may need to get a new roof (very expensive!) if your roof timbers become structurally unsound. A distinctive musty odour, a "spongy" feel to your timbers and indications of a black fungus, could all herald the existence of wet rot. When you spot any of these signs of wet rot, dealing with the issue immediately is essential to prevent further damage and the potential need for costly roof replacement.

Some simple measures can help prevent this, such as: repointing unsound brickwork, inspecting pipework for leaks and cleaning and checking your roof & guttering for leaks. A knowledgeable Hersham damp proof specialist will check all of these areas in order to help prevent any future problems, as part of solving your damp issues.


Condensation Damp Hersham UK (01932)

Lots of properties in Hersham suffer from condensation problems, and this is one of the most common causes of damp. When humid, warm air makes contact with a cool surface, water collects as small droplets. It often arises because of inadequate ventilation in areas where there is high humidity, i.e. kitchens, bathrooms and boiler rooms.

To minimise the impact of this there are two basic steps that you can follow. You can wipe away any droplets of water as soon as they arise, and you can ensure that there's good ventilation in areas that suffer most from condensation. To help remove the humid air from your home, you might need to upgrade or install air bricks, extractor fans and cooker hoods.

The best way to identify the key factors that contribute to the situation, is to get a detailed damp proofing survey carried out by a trustworthy Hersham company. With some properties moist air can be drawn in from the outside, plainly making matters worse. So as to manage condensation issues, it's vital that circulation and airflow within the home is effectively regulated, and by chatting to an expert on this subject, you'll be able to get advice and guidance for solving these issues.

Damp Proofing Quotes in Hersham Surrey


A damp proof course has been compulsory on houses constructed in the UK since 1875. You may not have a damp course installed on your home in Hersham if it was built earlier than this. If your home was built after this year, but you're still experiencing rising damp issues, it may be that the damp course or damp proof membrane has been compromised.

If you think that you may have rising damp in your home, a white powdery deposit being found on floor surfaces or forming on walls, "tide marks" on walls and crumbling or rotten skirtings, are good signs that you may be correct. Although the existence of these is not conclusive, they are all indications of rising damp.

Rising Damp Hersham Surrey

Remedying rising damp problems can be as simple as checking your property's outside walls and seeing if you can see a DPM. For adequate protection it needs to be 150 millimetres above the level of the ground. If this isn't the case you can dig away the ground to generate this space, or if this isn't possible, you could install a higher damp course.

If your damp proof course is in fact correct and the gap from the ground is not the cause of the problem, moisture might be coming up through your flooring and into your walls, which might be a more problematic issue.

Using a number of procedures, damp proofing experts in Hersham will swiftly detect and eliminate your rising damp problems. If you have an older property with no damp proof membrane or one that's damaged over a significant area, a damp proof cream can be carefully injected into your walls. This cream is injected with a special nozzle into evenly spaced holes drilled along the mortar joint, and before the cream sets it turns into liquid and soaks into the adjoining brickwork forming a barrier that is repellent to water.

If the damp proof cream is not appropriate, or the damage to your DPM is too extensive, a new damp proof course might need to be put in. This is the most drastic of repair works, but it could be the only resolution to your damp issues.

Damp Proofers Hersham (KT12)

For smaller areas of damage, yet another possible solution would be to coat with a waterproof (bitumen based) latex emulsion. Because this is applied underneath your floor coverings, wooden flooring, carpets and tiles must be lifted before this process can begin. Also used as an integral part of the "tanking" procedure to make a room watertight, this is a particularly effectual treatment in basements. For additional protection in these problem areas, your Hersham damp proofing technician might advise the use of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried out.

Tanking: Tanking a room, such as a basement or part below ground area, is a process of coating any exposed surfaces in a waterproof paint. This should be applied on the base surface of floors and walls, therefore all wall coverings and plaster must be removed and the surfaces properly prepared before the commencement of any work. Once this paint has been put on and dried, it's then possible to replaster any walls and decorate over it. Since it must be applied to an entire basement level or ground floor of a building, this is a very disruptive process. Therefore, it is a good idea to seek the advice of more than one damp proofing specialist to guarantee that this is really the only resolution.


Condensation issues can certainly be helped by the use of dehumidifiers, which are an effective way of reducing the moisture content in the air. Because dehumidifiers primarily alleviate the cause of the damp and don't cure it, there are issues with this solution. To get the best advice if you are suffering with damp or mould in any area of your house, you should call on a certified damp proofing company in Hersham.


Friends and family should always be your first port of call when you are looking for recommendations for local specialists. When possible you should always see if you can acquire at least 2 or 3 different estimates from a variety of companies, and before employing any specific damp proofing services, you can ask to see professional membership certificates and accreditations, as evidence of their credibility.

Watch out for contractors holding the CSTDB (Certificated Surveyor of Timber and Dampness) or the Certificated Surveyor in Remedial Treatments accreditations, or companies who are registered members of the DPA (Damp Proofing Association) or the Property Care Association.

You can be sure that your damp proofing provider is suitably qualified and has acquired the required experience to carry out a first class damp proofing service, if they are members of either the PCA or DPA. Such memberships also means that there are guarantees for any work undertaken.
