  • Penetrating Damp

  • Condensation

  • Rising Damp


In paragraphs that follow, we will have a look at what leads to such damp problems, and how you can go about solving them, and stopping them from occurring.


Common exterior issues like: unsound brickwork, damaged guttering or downpipes, cavity wall problems and loose or broken roof tiles, can all be major causes of penetrating damp. Inside your Hemel Hempstead home, penetrating damp can be the result of overflowing bathtubs or sinks, damaged shower trays and burst or leaking pipework. Visible signs such as broken or blistering plaster, flaking paintwork and damp, dark patches on walls, all point to the reality that these problems have been left uncontrolled.

You could get wet rot developing in your roof timbers, if you've got a leaking roof, and it's been left untreated for some time. While it doesn't spread into your brickwork, wet rot can cause your roof timbers to become structurally unsound, and in a worst case scenario you could even need to replace the entire roof - extremely costly! Wet rot can be recognised by the appearance of black fungus on your woodwork and a "spongy" feel to the rafters, along with an unfamiliar musty smell from the rotting timber. If you detect any of these wet rot symptoms, it is imperative to address the issue quickly to prevent further harm and the potential for a expensive roof replacement.

You shouldn't panic however, since to stop these problems happening, a few simple steps such as examining water pipes for leaks, cleaning your roof & rain gutters and checking for leaks and repointing dodgy brickwork, should reduce such concerns. If you contact a competent damp proofing service in Hemel Hempstead, they'll check all of these things, and prepare a strategy for both fixing your damp issues and forestalling further occurrences.


Condensation Damp Hemel Hempstead UK (01442)

Condensation is extremely easy to spot and is a common form of damp within many homes in Hemel Hempstead. Tiny droplets of water appear on cool surfaces when they come into contact with warm, moist air. Inadequate ventilation in areas with high humidity, such as in kitchens, bathrooms and boiler rooms, is the most frequent explanation for condensation.

To reduce the impact of this there are a couple of basic steps that you can take. You can mop up any droplets the instant they appear, and you can ensure that there is good ventilation in areas that most suffer from condensation. The necessary steps may require the updating or installation of cooker hoods, air bricks and extractor fans, with the intention of redirecting damp air outside of your property in Hemel Hempstead.

An in-depth damp proofing survey by a trusted Hemel Hempstead company may also find circumstances which exacerbate the issue by drawing in moist air from outside. So as to minimise condensation problems, it's essential that circulation and airflow in the home is regulated correctly, and by chatting to an expert on this topic, you will be able to get advice and information for solving these issues.

Damp Proofing Quotes in Hemel Hempstead Hertfordshire


A damp proof course has been installed as standard on houses built in Great Britain since 1875. If your property or home was built before this time it's conceivable that you may not have this installed. If you are suffering with rising damp in a house built after this period it may be that your damp proof course or damp proof membrane has been damaged in some way.

Although hard to identify, a white powdery deposit being discovered on floor surfaces or forming on walls, crumbling or rotten skirtings and tide marks on walls, are all giveaway clues that you might have rising damp. It's possible that you might have a rising damp problem if you've noticed one or all of these in your property.

Rising Damp Hemel Hempstead Hertfordshire

The first step towards resolving your rising damp problems should be to simply check whether or not you have in fact got a damp course on the exterior walls of your property in Hemel Hempstead. For adequate protection it should be 150 millimetres (approximately six inches) above ground level. If you find that this space does not exist, you could dig the earth away to increase it, or if this process isn't plausible, a higher damp proof membrane will have to be put in.

You may have more challenging issues if you learn that your damp proof membrane is OK, and it may be that the moisture is rising from the ground, up through your flooring, and into the walls, which can be an even more troubling predicament.

Damp proofing experts in Hemel Hempstead can swiftly identify and resolve rising damp using a range of techniques. Older properties which either have no damp proof course, or have a compromised one that is damaged over a wide area, can be treated with a damp proofing injection cream such as Permaguard. Holes are drilled at intervals along the mortar course, and a special nozzle is used to inject the cream, which then penetrates into the surrounding brickwork before curing to form an effective, horizontal water-repellent barrier.

If the damp proofing cream isn't appropriate, or the damage to your membrane is too extensive, a brand new damp proof course may need to be installed. Whilst this sort of repair work is a fairly extreme way to solve rising damp issues, it could be your only effective solution in the final analysis.

Yet another option for less severe areas of damp course damage may include painting on a layer a waterproof (bitumen based) latex emulsion coating. This will be applied beneath your floor coverings, so carpets, wood flooring and tiles will have to be lifted before any work can be done. In cellars this is a particularly efficacious treatment, and will form a part of the tanking process that is used to make rooms watertight. For further protection in these troublesome areas, your Hemel Hempstead damp proofing technician might suggest a layer of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried.

Tanking: The process of covering exposed surfaces in a waterproof paint in a below ground area such as a cellar is called "tanking". This has to be applied at the base level of floors and walls, therefore all plaster and wall coverings must be removed and the appropriate surfaces prepared properly before work commences. As soon as the coating has been applied and dried, it's then the time to replaster the wall surfaces and decorate on top of it. This is an extremely disruptive job since it has to be applied to a whole basement level or ground floor of a building, and it is recommended that you obtain more than one specialist opinion on whether this is the only answer to your rising damp problems.


To help with problems with condensation, you could try using dehumidifiers, which for lowering the moisture content of the air, are pretty efficacious. The drawback with the use of dehumidifiers in attempting to reduce damp and mould is that they merely alleviate the cause of the damp, don't cure it. To get the most reliable advice if you're suffering from damp or mould in any area of your house, you can contact an experienced damp proofing specialist in Hemel Hempstead.

These treatments deeply penetrate the timber and eliminate the larvae. This method is most effective for minor infestations, and a professional will decide whether this is the most suitable option. For more severe infestations, fumigation may be the answer. This involves sealing the affected area and discharging a gas into the space to kill off the larvae. Fumigation is a lot more invasive, however it's often the best treatment for larger infestations.

To prevent woodworm infestations, it's important to ensure that the environment is not conducive to their growth.

Using wood that has been treated with a woodworm repellent can also prevent future infestations.
