Damp Proofing Harpenden Hertfordshire (AL5)


  • Penetrating Damp

  • Condensation

  • Rising Damp


The following paragraphs describe what may cause such damp problems in Harpenden, and the different ways of avoiding and solving them.


Things like cracks in brickwork, cavity wall problems, defective guttering and broken roof tiles are all external causes of penetrating damp in your home. Inside, damaged shower trays, overflowing bathtubs or basins and leaking or burst pipes, can lead to penetrating damp. If water continues to soak into the walls and woodwork, the visible signs over time will be broken or blistering plaster, damp dark patches on walls and peeling paintwork.

Wet rot can develop in your roof timbers if you've got a leaking roof that's left untreated over a long period of time. Even though it is lucky that wet rot does not affect brickwork, in a worst case scenario, you may need to replace the whole roof (very costly!) if the timbers of your roof become unsound structurally. An unusual musty odour, a "spongy" feel to your roof timbers and signs of black fungus growth, could all signify the presence of wet rot.

You need not fret however, since to prevent these problems occurring, a few simple steps like cleaning and checking your rain gutters and roof for leaks, repointing dodgy brickwork and inspecting pipes for leaks should avoid such issues. If you use the services of a certified Harpenden damp proofing provider, they'll check all these areas as a part of your complete damp proofing arrangement.


Condensation Damp Harpenden UK (01582)

A common form of damp in many houses in Harpenden, condensation is super easy to spot. Tiny droplets of water form on colder surfaces when humid, warm air comes into contact with these surfaces. In areas with high humidity, such as: kitchens, bathrooms and boiler rooms, it's often caused due to poor ventilation.

To stop condensation problems, basic solutions include making certain there is adequate ventilation in the affected areas, and wiping up any droplets of water as soon as they arise. Redirecting moist air outside of your home in Harpenden, by fitting or updating extractor fans, air bricks and cooker hoods, will help you to solve this problem.

There could possibly be issues with drawing in damp air from the outside, and by conducting a detailed damp proof survey a specialist in Harpenden will identify areas that give rise to the situation. To satisfactorily minimise condensation problems, airflow must be properly regulated. A knowledgeable Harpenden damp proofing specialist will be able to offer solutions and advice in regards to this.

Damp Proofing Quotes in Harpenden Hertfordshire


Homes built since 1875 in Great Britain have been required to have a damp proof course or membrane to be installed as standard. It's possible that you may not have one installed if your house in Harpenden was built before this time. If you're experiencing rising damp in a house built after this time it may be that your damp proof course or membrane has been damaged somehow.

If you think that you might have rising damp in your home, "tide marks" on walls, a white powdery deposit being found on floor surfaces or appearing on walls and crumbling or rotten skirtings, are good indications that you may be right. Although the existence of these isn't conclusive, they're all clear indications of rising damp issues.

Rising Damp Harpenden Hertfordshire

The first step towards solving your problems with rising damp should be to simply check whether you have in fact got a damp proof course on the exterior walls of your property in Harpenden. It needs to be 150mm (approximately 6") above the level of the ground for satisfactory protection. Where you discover this space does not exist, you can dig away the ground to increase it, or if this approach is not possible, a higher DPM (damp proof membrane) will have to be put in.

If this is not the problem and your damp proof membrane is installed and in order, there could be more problematic issues to resolve caused by the dampness coming up from the ground, up through your flooring, and into the walls of your property.

Using a variety of procedures, damp proofing specialists in Harpenden will quickly identify and solve rising damp issues. If you have an older property with no damp proof course or it is damaged over an extensive area, a damp proof cream (such as Permaguard) can be injected into your wall. Holes will be drilled at intervals along the mortar joint, and a special nozzle is used to inject the cream, which then diffuses before curing to form an effective, horizontal waterproof barrier.

If the deterioration of your DPM is too extensive, or if damp proofing cream isn't a satisfactory treatment, you might need to install a new damp proof course. This is the most drastic of repair works, however it could be the only answer to your damp issues.

Another remedy for less severe areas of damp course damage might include painting with a waterproof (bitumen based) latex emulsion. Tiles, carpeting or wood flooring will need to be lifted before any work can be done, because it is applied underneath your existing floor coverings. This is especially efficacious in cellars as part of the tanking procedure to create a watertight room. For extra protection in these trouble spots, your Harpenden damp proof expert may advise applying building paper (a specialist foil backed membrane) before the bitumen paint has completely dried.

Tanking: The process of coating exposed surfaces in a watertight paint in a cellar or below ground area is called tanking. This has to be applied on the base surface of floors and walls, therefore all plaster and wall covering must be removed and the relevant surfaces prepared correctly before the commencement of any work. You can replaster and decorate on top of it, after the paint has dried out completely. As it needs to be applied to an entire basement level or ground floor of a building, this is a highly disruptive process. Therefore, it's wise to bring in more than one damp proofing specialist to ensure that this really is the only possible option.


Dehumidifiers are a highly effective way to remove moisture from the air, so for condensation issues they can help. The trouble with dehumidifier use in trying to stop damp is that they basically hide the cause of the damp, not cure it. A professional damp proofing specialist in Harpenden will be delighted to offer advice on the best solution if you're experiencing mould or damp in any area of your property.


The best recommendations for local professionals with regards to home improvement projects are generally friends and relations.

If your chosen Harpenden damp proofing specialists are members of the DPA or PCA you can be certain they'll be properly qualified and have acquired the necessary working experience to provide you with a top notch service for all your damp proofing problems. Any work carried out by any one of their members is also guaranteed.
