  • Penetrating Damp

  • Condensation

  • Rising Damp


To learn what the possible reasons for such damp problems are, and how to fix them, keep on reading...


Penetrating damp can be attributable to a range of external factors such as: damaged or porous brickwork, damaged guttering or downpipes, loose or broken roof tiles and blocked cavity walls. In the interior of your home it can be a result of overflowing baths or sinks, leaky or burst pipework and cracked shower trays. Woodwork and walls can be impacted if left uncontrolled, and will be noticeable as flaking paintwork, broken or blistering plaster and damp, dark patches on walls.

You could get wet rot in your roofing timbers, if you've got a leaky roof, and it has been left untreated for some time. In the worst case scenario, you may even need to rebuild the entire roof, because wet rot can cause severe issues with the structural integrity of your roof timbers. If a black fungus appears on your woodwork and the timber in your roof feels "spongy" to the touch, you may have problems with wet rot.

You should not panic however, since to stop these problems occurring, a few straightforward steps like cleaning and checking your gutters & roof for leaks, repointing brickwork and inspecting piping for leaks, should avoid such situations. A certified damp proofer in Cranleigh will check these areas in order to help avoid any future complications, as an element of resolving your issues with dampness.


Condensation Damp Cranleigh UK (01483)

A common form of damp in Cranleigh homes, condensation is extremely easy to spot. When cooler surfaces make contact with moist, warm air, tiny water droplets form on those cold surfaces. Condensation is commonly found in areas with high humidity and poor ventilation, such as in kitchens, boiler rooms and bathrooms.

To stop condensation issues, easy strategies include making sure that you have enough ventilation in the affected areas, and wiping away any water droplets the moment they form. You can minimise the quantity of moist air which is present in your house by fitting or upgrading air bricks, cooker hoods and extractor fans.

An in-depth damp proofing survey from an established Cranleigh specialist may also find factors which exacerbate the issue by drawing in damp air from outside. It is crucial that airflow and circulation is effectively regulated, in order to control condensation problems, and you will be able to get advice and information on this from a damp proofing specialist.

Damp Proofing Quotes in Cranleigh Surrey


Homes built since 1875 in the United Kingdom have required a damp proof course to be fitted as standard. It's perfectly possible that you may not have one installed if your property or home in Cranleigh was built before this year. If your house was constructed after this year, but you are still experiencing rising damp problems, it could be that the DPM has been compromised.

Rising damp can be difficult to distinguish, but some areas to keep an eye out for are; rotten or crumbling skirting boards, white powdery deposits forming on walls or being found on floor surfaces and "tide marks" on walls. If you notice or think you might have any of these, it is possible you have a rising damp problem.

Rising Damp Cranleigh Surrey

Dealing with rising damp problems can be as easy as checking your exterior walls and seeing if you can see a DPM. In order to get a satisfactory measure of protection the damp proof membrane ought to be above ground level by a minimum of 150 millimetres (about 6"). If you discover that this gap does not exist, you could dig the earth away to increase it, or if this approach isn't possible, a higher damp proof course will have to be installed.

If this is not the root cause of the problem and your damp proof course is installed and in order, there may be more problematic issues to deal with caused by the dampness rising up from the ground beneath, through your floor, and into the walls.

Cranleigh damp proofing technicians will quickly be able to determine the explanation for your rising damp issues, and using a range of techniques will quickly fix the problem. Older homes which either have no damp proof membrane at all, or have one which is damaged over a considerable area, can be treated with a damp proofing injection cream. Evenly spaced holes are drilled at intervals in the mortar course, and a nozzle is used to inject the special cream, which then penetrates into the surrounding brickwork before curing to form an effective, horizontal water-repellent barrier.

In instances where damp proofing cream injection isn't an appropriate remedy, or when the membrane is severely damaged, installing a whole new damp proof course could be neccessary. Although this is of course a fairly drastic course of action, it may be the best way to resolve your rising damp issues effectively.

For smaller areas of damage, another possible solution could be to coat with a waterproof (bitumen based) latex emulsion paint. Wood flooring, tiles or carpets must be lifted prior to work being undertaken, since it's applied under your existing floor coverings. In cellar areas this is a particularly effective treatment, and will form a part of the "tanking" process which is used to make spaces watertight. Before the bitumen paint has completely dried out, your Cranleigh damp proof technician might recommend the application of building paper (a foil backed specialist membrane), for additional protection.

Tanking: Tanking an area, such as a basement or below ground area, is a process of coating any exposed surfaces with a waterproof paint. Any plaster and wall coverings must be removed and the appropriate surfaces correctly prepared before the commencement of any work, as this waterproof coating must be applied on the base surface of walls and floors. As soon as this coating has been applied and dried, it's then possible to replaster and decorate on top of it. You should invariably get more than one specialist's opinion about whether this really is the only remedy for your rising damp, since this is an extremely disruptive process because it must be applied to an entire basement level or ground floor of a building.


Condensation problems can definitely be helped by means of dehumidifiers, which are a highly effective way of reducing the moisture content in the air. The fact that these products basically hide the cause of the damp and not get rid of it, is the drawback with dehumidifier use. A competent damp proofing specialist in Cranleigh will be delighted to offer advice on the best solution if you're suffering from mould or damp in any part of your home.


Friends and neighbours should always be your first choice when you're looking for recommendations for local specialists. Where possible you should try to get at least two or three different estimates from a number of companies, and before signing up to any specific damp proofing providers, you should ask to see qualifications and professional memberships, as a verification of their trustworthiness.

Keep an eye out for membership of and qualifications from organisations such as the Property Care Association (PCA) or the Damp Proofing Association, or contractors holding the Certificated Surveyor of Timber and Dampness (CSTDB) or the Certificated Surveyor in Remedial Treatments qualifications.

Membership of the DPA or PCA guarantees your preferred damp proofing specialist is suitably qualified and has the appropriate experience to offer a first class damp proof service. Any work carried out by one of their members also comes with a guarantee.
