Damp Proofing Croxley Green Hertfordshire (WD3)


  • Penetrating Damp

  • Condensation

  • Rising Damp


The following article describes the causes of such damp problems in Croxley Green, and the different techniques for avoiding and resolving them.


A few of the exterior issues that can cause penetrating damp in a property include: damaged downpipes or guttering, unsound brickwork, cracked roof tiles and cavity wall problems. In the interior of your home it can be due to cracked shower trays, overflowing basins or bathtubs and burst or dripping pipes. Visible signs like peeling paintwork, blistered or broken plaster and damp, dark patches on walls, all suggest that these issues have been left unresolved for some time.

You could get wet rot developing in your roofing timbers, if you have a leaky roof, and it has been neglected for some time. Although brickwork is not affected by wet rot, your roof timbers can be seriously damaged, 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 appears on the wood, you might have wet rot in your roof.

You shouldn't panic however, since to prevent these problems from happening, a few straightforward steps such as cleaning and checking your roof & guttering for leaks, examining pipes for leaks and repointing brickwork, should avoid such concerns. As an integral part of fixing your dampness issues, a professional Croxley Green damp proofing service provider will check all of these areas, in order to help reduce the chances of any further issues.


Condensation Damp Croxley Green UK (01923)

Super easy to spot and a contributing factor to damp in many Croxley Green properties, condensation is very common. Tiny water droplets form on cold surfaces when they make contact with warm, moist air. In places where high humidity is present, as in: kitchens, bathrooms and boiler rooms, condensation forms due to inadequate ventilation.

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

In some cases moist air can be sucked in from outside, plainly making the situation even worse. And the best way to establish the main circumstances that bring about the problem, is to get an in-depth damp proofing survey carried out by a trusted Croxley Green damp proofing company. To satisfactorily minimise condensation problems, airflow and circulation must be regulated properly. A reliable Croxley Green damp proofing technician will be able to offer solutions and advice in regards to this.

Damp Proofing Quotes in Croxley Green Hertfordshire


Ever since 1875, a damp proof course has been compulsory in all homes built in Great Britain. If your home was constructed before this period it's perfectly possible that you might not have one installed. It is possible that your DPM could have been damaged somehow if you are experiencing rising damp issues in a home built after this year.

Although notoriously difficult to distinguish, "tide marks" on walls, white powdery deposits being discovered on floor surfaces or appearing on walls and crumbling or rotten skirtings, are all giveaway indications of rising damp. Although the existence of these is not conclusive, they're all indications of rising damp problems.

Rising Damp Croxley Green Hertfordshire

Dealing with rising damp issues can be as straightforward as checking your external walls and seeing if you can see a DPM. To be certain of a satisfactory measure of protection the damp proof course should be above ground level by at least 150mm (about 6"). If this isn't the situation you might be able to dig away the ground to create this space, or if this is not plausible, you can put in a damp proof membrane (DPM) higher up.

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

Damp proofing specialists in Croxley Green will quickly detect and eliminate rising damp problems using a range of methods. Older properties which either don't have a DPM, or have a compromised one which is damaged over a considerable area, can be treated with a damp proof injection cream. This special cream is injected with a nozzle into evenly spaced holes drilled along the mortar joint, and before the cream can cure it turns into liquid and penetrates into the adjoining brickwork creating a barrier that is water-repellent.

If the damage to your DPM is too critical, or if damp proofing injection cream isn't an appropriate solution, you may have to install a brand new damp proof course. Though this is obviously a pretty drastic course of action, it may be the only method to solve your damp problems effectively.

For less severe areas of membrane damage, another potential remedy could be to coat with a bitumen based, waterproof latex emulsion. Because this will be applied underneath any existing floor coverings, carpeting, tiles and laminate flooring will need to be lifted and moved before this procedure can begin. In cellar areas this is an especially efficacious treatment, and will form an integral part of the tanking procedure that's used to create watertight spaces. For added protection in those trouble spots, your Croxley Green damp proofing technician might recommend applying building paper (a specialist foil backed membrane) before the bitumen coating has dried completely.

Tanking: In cellars and below ground areas of a house, "tanking" is a process where exposed surfaces are covered in a waterproof coating. Since this waterproof coating has to be applied to the bare surface of floors and walls, any wall covering and plaster must be taken off before any work can begin, and the surfaces in question prepared properly. When this paint has been put on, it must be allowed to dry out thoroughly before replastering and decorating over the top of it. Since it needs to be applied to an entire basement level or ground floor of a building, this is an incredibly disruptive process. It is therefore advisable to seek the advice of at least two or three damp proofing companies to guarantee that this is really the only possible solution.


To help with problems with condensation, you could always try dehumidifiers, which for lowering the moisture content of the air, are quite effective. The fact that they just mask the cause of the damp and don't cure it, is the main disadvantage with the use of dehumidifiers. If you're experiencing damp or mould in any part of your home in Croxley Green, you should call on a competent damp proofing specialist for the best advice.


The best recommendations for local professionals with regards to home improvement projects are usually neighbours and friends. When possible you should always try to obtain at least 2 or 3 different quotes from a number of companies, and before signing up to any particular damp proofing providers, you should ask to look at professional memberships and qualifications, as evidence of their credibility.

Keep an eye out for technicians holding the CSRT (Certificated Surveyor in Remedial Treatments) or the CSTDB (Certificated Surveyor of Timber and Dampness) qualifications, or companies who are signed up members of the Damp Proofing Association or the Property Care Association.

Membership of the DPA or PCA guarantees that your selected damp proofing specialist is suitably qualified and has the appropriate experience to provide a high quality damp proofing service. This also offers guarantees on any work undertaken by one of their membership.

Black Mould Croxley Green

The first step in removing mould is to clean the affected area with soapy water. You should also use a disinfectant such as bleach, which can kill any mould spores. Hydrogen peroxide and white vinegar are also effective disinfectants. However, you should be cautious when using bleach, because it could burn and irritate your eyes. Also, make certain there's good ventilation in the room where you're working, to help clear away the fumes.

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