There are various external issues that can cause penetrating damp in a building, and included in these are: blocked cavity walls, defective gutters or drainpipes, damaged or porous brickwork and cracked roof tiles. Inside your Horsham property, it can be a result of overflowing basins or bathtubs, damaged shower trays and burst or leaking water pipes. If left to continue leaking these factors allow water to seep into the woodwork and walls, which in time result in flaking or bubbling paintwork, dark, damp patches on walls and blistering or broken plaster.

You can get wet rot in your roofing timbers, if you've got a leaky roof, and it has been left untreated for an extended period of time. In the worst case scenario, you may even have to rebuild the entire roof, as wet rot can cause severe problems with the structural integrity of your roofing timbers. If your roof timbers feel "spongy" when touched, and a black fungus starts appearing the wood, you might have a case of wet rot in your roof.

Simple steps like cleaning your guttering & roof and checking for leaks, repointing brickwork and examining pipes for leaks, are the basic preventative maintenance measures. As an integral part of dealing with your damp problems, a certified Horsham damp proofing service provider will check all of these things, in order to help reduce the chances of any further issues in the future.


Condensation Damp Horsham UK (01403)

Quite simple to identify and a contributing factor to damp in a lot of Horsham properties, condensation is extremely common. Tiny droplets of water form on cool surfaces when warm, humid air comes into contact with them. It often arises due to inadequate ventilation in places where there's high humidity, i.e. boiler rooms, bathrooms and kitchens.

Among the more quick answers to condensation include wiping water droplets away the moment they arise, and making certain that troublesome areas have adequate ventilation. This may involve the installation or updating of cooker hoods, air bricks and extractors to help redirect the moisture laden air outside of the building.

The best way to identify the key circumstances that contribute to the problem, is to get an in-depth damp proofing survey done by a reputable Horsham company. Sometimes moist air can be sucked in from outside, plainly making matters worse. A specialist on this topic will be able to offer advice, information and solutions on this matter, because to ensure that condensation problems are controlled, any air circulation within the home must be correctly regulated.

Damp Proofing Quotes in Horsham West Sussex


A damp proof course has been compulsory on homes constructed in the United Kingdom since 1875. If your home or property was built before this period it's possible you may not have one installed. If your property was constructed after this year, but you are still experiencing rising damp, it could be that your damp proof course has been damaged.

Although tricky to identify, "tide marks" on walls, rotten or crumbling skirtings and white powdery deposits being discovered on floor surfaces or appearing on walls, are all giveaway indications of rising damp. It is plausible that you could have a rising damp issue if you've spotted one or more of these.

Rising Damp Horsham West Sussex

Simply checking your property's external walls to spot if you've got a damp proof course can be one step towards solving your problems with rising damp. In order to get a satisfactory measure of protection the DPM ought to be above ground level by at least 150 millimetres (approximately 6"). You could dig the surrounding soil away to generate this space if it is currently not sufficient, or you can put in a damp course higher up if the first option is not plausible.

If your DPM is in fact correct and the gap from the ground isn't the cause of the problem, moisture may be coming up through your floors and into your walls, which might be a much more problematic issue.

Using a variety of procedures, damp proofing specialists in Horsham can swiftly identify and resolve your rising damp problems. A damp proof cream (such as Permaguard) can be carefully injected into your wall if you have an older property with no damp proof course, or one that is damaged over an extensive area. This special cream is injected with a nozzle into holes drilled evenly along the mortar course, and before the cream can cure it diffuses into the surrounding brickwork forming a barrier that is repellent to water.

If the damage to the damp course membrane is too critical, or if damp proofing injection cream isn't an appropriate solution, you might need to put in a new damp proof course. Though this is obviously a fairly extreme approach, it might be the best way to resolve your rising damp effectively.

Damp Proofers Horsham (RH12)

Another option for less severe areas of damage could include painting on a layer a bitumen based, waterproof latex emulsion coating. This is applied beneath your current floor coverings, so tiles, carpets and wood flooring will have to be lifted before any work is undertaken. Also used as a part of the tanking process to make a space watertight, this is an especially effectual solution in basement areas. Your Horsham damp proof expert may suggest applying building paper (a foil backed specialist membrane) before the bitumen coating has completely dried out, added protection in such troublesome areas.

Tanking: The process of covering exposed surfaces in a waterproof paint in a below ground area such as a cellar or basement is called "tanking". All plaster and wall coverings must be taken off and the surfaces in question prepared properly before any work begins, because this coating has to be applied at the base level of floors and walls. You can replaster the wall surfaces and decorate on top of it, as soon as the coating has completely dried out. You should invariably get more than one expert's opinion on whether this is really the only resolution to your rising damp issues, because this is a really disruptive process as it needs to be applied to a whole ground floor or basement level of a building.


Condensation problems can definitely be improved by means of dehumidifiers, which are an effective way to remove moisture from the air. The fact that these products simply alleviate the cause of the damp and not cure it, is the downside with dehumidifier use. A competent damp proofing specialist in Horsham will be ready to offer advice on the best solution if you're experiencing damp or mould in any area of your house.


As with pretty much any project, the most reliable recommendations for a specialist come from friends and relations. When possible you should always try to obtain at least 3 or 4 different estimates from a variety of companies, and before signing up for any particular damp proof providers, you should ask to look at professional membership certificates and accreditations, as evidence of their trustworthiness.

Look for membership of and qualifications from bodies such as the DPA (Damp Proofing Association) or the Property Care Association, or contractors holding the Certificated Surveyor in Remedial Treatments or the CSTDB (Certificated Surveyor of Timber and Dampness) accreditations.

If your selected Horsham damp proofing specialists are members of the DPA or PCA they'll be suitably qualified and have the necessary practical experience to provide you with a high quality service for your damp proofing needs. Any damp proofing work supplied by any one of their members is also guaranteed.

Dehumidifier Installation Horsham

Maintaining comfortable and healthy indoor air quality, particularly in spaces with high humidity levels, necessitates the use of dehumidifiers. Proper installation is crucial for the optimal performance and longevity of the unit.

Before installing a dehumidifier, it's important to select a suitable location that is free from obstructions and has an electricity socket nearby. Placing the unit on a flat surface and away from walls and furniture is essential to maintain sufficient air circulation.

Properly setting up the drainage system next is vital to prevent water damage or overflow. Connecting the dehumidifier to a drain or attaching a hose to the unit may be required to complete the process. The effective operation of the dehumidifier requires routine maintenance, such as cleaning or replacing the filter.

Considering the size of the dehumidifier in relation to the space or room it will be installed in is important. To ensure a successful and safe dehumidifier installation, it's advisable to consult the manufacturer's instructions or seek the assistance of a professional. Reduced moisture-related issues, improved indoor air quality, and enhanced overall comfort can be achieved in homes or businesses through proper dehumidifier installation and servicing.

Condensation Control Horsham

Condensation control is an important aspect of maintaining a healthy and comfortable indoor environment. When warm, moisture-laden air meets cooler surfaces, condensation takes place and leads to the formation of water droplets. Uncontrolled condensation can lead to the growth of mould, damage to building materials, and the deterioration of indoor air quality. Regulating the amount of humidity and promoting air circulation through proper ventilation is essential for controlling condensation. To minimise condensation and reduce temperature differentials, consider using double-glazed windows and insulation. Effective condensation management enables the prevention of potential problems and the creation of a more pleasant living or working environment.

Insulation and double-glazed windows can help to make a difference in reducing temperature differentials and minimising condensation. Cold surfaces are prevented from coming into direct contact with warm, moist air by insulation, which serves as a thermal barrier. Condensation is less likely to form on surfaces like ceilings, windows and walls if the temperature difference is reduced. Double-glazed windows, featuring 2 panes of glass with an insulating layer between, are effective at maintaining an even indoor temperature, further suppressing condensation.

Another effective condensation control technique is to address the sources of moisture head-on. Activities like cooking, showering and drying clothes indoors release moisture into the air. Kitchens and bathrooms with exhaust fans and adequate ventilation are less likely to have an excessive build-up of humidity. Maintaining optimal indoor humidity levels in areas at risk of high moisture content is possible with the use of dehumidifiers. (14876 - Condensation Control Horsham)
