  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you will find details of what may be causing damp problems in your home or business premises in Hemel Hempstead, and exactly how you may proceed with rectifying them.


Penetrating damp in your home can be attributable to different external factors for instance: blocked cavity walls, cracks in brickwork, defective gutters or downspouts and cracked roof tiles. Internal reasons for penetrating damp might be overflowing basins or bathtubs, cracked shower trays and leaking or burst water pipes. If left to carry on leaking these factors enable water to seep into woodwork and walls, which with time result in damp, dark patches on walls, flaking paintwork and blistering or broken plaster.

If neglected for an extended period of time, a leaky roof can cause wet rot in your roof timbers. Although bricks and brickwork are not impacted by wet rot, the timbers of your roof can suffer severe consequences, and the whole roof may need to be replaced if it becomes structurally unsound. If your roof timbers feel "spongy" to touch, and a black fungus forms on the wood, you probably have wet rot in your roof structure.

Simple steps like repointing dodgy brickwork, inspecting pipework for leaks and cleaning and checking your rain gutters & roof for leaks, are the basic preventative maintenance measures. If you contact a knowledgeable damp proofing service in Hemel Hempstead, they can check all of these areas, and prepare a plan for both resolving your dampness problems and preventing further occurrences.


Condensation Damp Hemel Hempstead UK (01442)

A common form of damp in many properties in Hemel Hempstead, condensation is extremely easy to identify. When moist, warm air makes contact with colder surfaces, droplets of water immediately appear. If there is not adequate ventilation in areas with a high level of humidity, such as boiler rooms, kitchens and bathrooms, condensation can often be a consequence.

Wiping up any droplets of water that form, and ensuring there's enough ventilation in the worst affected areas, are amongst the simplest solutions to such issues. You can minimise the level of moisture laden air that's present in your house by updating or fitting extractor fans, cooker hoods and air bricks.

There could possibly be issues with sucking in damp air from the outside, and by performing a detailed damp proofing survey a specialist in Hemel Hempstead will be able to identify things that exacerbate the problem. An expert on this subject will be able to offer solutions, advice and information on this matter, because for condensation problems to be controlled, airflow and circulation within the home must be effectively regulated.

Damp Proofing Quotes in Hemel Hempstead Hertfordshire


A damp proof course or membrane has been fitted as standard on houses built in Great Britain since 1875. If your property was built before this period it's possible that you may not have one installed. It's a possibility that your damp proof course or damp proof membrane may have been damaged in some way if you are experiencing rising damp problems in a home built after this year.

Although quite difficult to distinguish, crumbling or rotten skirtings, tide marks on walls and white powdery deposits being found on floor surfaces or forming on walls, are all giveaway clues that you may have rising damp. Although the existence of these isn't conclusive, they are all indications of rising damp.

Rising Damp Hemel Hempstead Hertfordshire

Just checking your property's exterior walls to see if you have a damp course can be one step towards solving your problems with rising damp. For satisfactory protection it ought to be 150 millimetres (approximately 6 inches) above ground level. If this is not the case you can dig the ground away to generate this space, or if this isn't feasible, you could install a higher damp proof membrane (DPM).

If this isn't the problem and your DPM (damp proof membrane) is correct, there might be more serious issues to resolve caused by the moisture coming up from the ground beneath, up through your floors, and into the walls.

Using a number of techniques, damp proofing specialists in Hemel Hempstead can quickly detect and remedy rising damp issues. If you have an older home with no damp proof course or it is damaged over an extensive area, a damp proof cream (such as Permaguard) can be carefully injected into your wall. Holes will be drilled at intervals along the mortar course, and a special nozzle used to inject the cream, which then penetrates into the surrounding brickwork before curing to form an effective, horizontal water-repellent barrier.

If the damage to your membrane is too drastic, or if damp proofing cream isn't a satisfactory solution, you may have to install a new damp proof course. Whilst this sort of repair work is a pretty extreme way to solve damp issues, it could be the only real solution when all is said and done.

For smaller areas of damp course damage, another possible remedy could be to coat with a bitumen based, waterproof latex emulsion paint. Laminate flooring, carpeting or tiles must be lifted before any work can be done, as it's applied under your floor coverings. Also used as a part of the "tanking" procedure to make a space watertight, this is an especially efficacious solution in basements. For further protection in such problem areas, your Hemel Hempstead damp proofing expert might suggest laying building paper (a specialist foil backed membrane) before the bitumen paint has completely dried out.

Tanking: The process of covering exposed surfaces in a watertight paint in a basement or below ground area is known as "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. When the paint has been put on and dried, it's then possible to replaster any walls and decorate over it. You should always get more than one expert's opinion on whether this is the only answer to your rising damp, because this is an extremely disruptive job as it needs to be applied to a whole ground floor or basement level of a property.


Problems with condensation can definitely be improved by means of dehumidifiers, which are a highly efficacious way to remove moisture from the air. The main problem with dehumidifier use in trying to eliminate damp is that they simply hide the cause of the damp, not cure it. To obtain the most reliable advice if you are experiencing dampness in any part of your home, you should contact a professional damp proofing company in Hemel Hempstead.


Friends and relatives should invariably be your first port of call when you are trying to get recommendations for local professionals. When possible you should see if you can get at least 3 or 4 different estimates from a number of companies, and before signing up for any particular damp proofing services, you can ask to look at professional membership certificates and qualifications, as a verification of their trustworthiness.

Watch out for technicians holding the Certificated Surveyor in Remedial Treatments or the CSTDB (Certificated Surveyor of Timber and Dampness) professional qualifications, or local companies who are members of the DPA (Damp Proofing Association) or the Property Care Association (PCA).

Membership of the DPA or PCA guarantees your chosen damp proofing specialist is well qualified and has the appropriate experience to provide you with a high quality damp proof service. Any remedial work supplied by any one of their members is also guaranteed.

Positive Input Ventilation Hemel Hempstead

PIV (Positive Input Ventilation) may be a perfect solution to alleviate issues with damp in your home in Hemel Hempstead. If you have noticed mould and damp inside your dwelling or condensation around your windows then Positive Input Ventilation can help to reduce the humidity. It accomplishes this by continually circulating fresh air. This constant replacement and refresh of the air inside your home increases air quality, reduces pollutants and odours and has been proven to enhance the day to day life of asthma and allergy sufferers by reducing dust mite allergens. One thing about PIV systems is that they work best when installed in a roof space, and your property does need to be relatively airtight. Air, like water, takes the path of least resistance, and any gaps in windows or doors will let the fresh air get out, whilst bringing possible contaminated air in from the outside environment.

Black Mould Problems

Black mould is a common problem in homes in Hemel Hempstead, especially those with lots of wood. This fungus is considered to be toxic. It produces conidia and slime heads, which are a sign of its presence. If you discover this form of mould in your home in Hemel Hempstead, it's vital to remove it right away. If you think you could have black mould, it's important to get it checked by a professional. Experienced damp proof specialists in Hemel Hempstead can conduct surveys and provide you with a free quotation. If you're concerned that the mould issue is damaging your health, a damp proofing contractor can do an inspection to determine the severity of the issue.

Black Mould Hemel Hempstead

Fortunately, there are quite a few techniques for getting rid of black mould. The first strategy uses white vinegar, which is an environmentally-friendly solution. You can apply neat vinegar to large areas, or mix it fifty, fifty with water for smaller sections. Once it has been applied, the vinegar solution should stay on the mould for at least one hour before rubbing off.

Another procedure involves increasing air flow in your home. It is thought that black mould is more likely to grow in areas of the house that lack adequate ventilation. Even though this cannot completely eliminate the risk, it's still important to make certain that the air is getting out of the house as much as possible. Open the windows so that fresh air can flow in and out.

Another approach is the use of a water and baking soda paste to treat the mould. This solution has a pH of 2.5, making it an effective antibacterial. Hydrogen peroxide is another treatment that can be effective for getting rid of black mould. It's a natural, 3 in 1 solution that is safe to use, particularly on porous surfaces.
