Damp Proofing Derry Northern Ireland (BT47)


  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you'll find details of what might cause damp problems in your home in Derry, and how you may proceed with fixing them.


Penetrating damp in your home can be caused by different external factors for example: defective guttering, cavity wall problems, unsound brickwork and loose or broken roof tiles. Inside your Derry property, penetrating damp can result from overflowing basins or baths, leaky or burst pipes and cracked shower trays. If water continues to seep into the walls and woodwork, the obvious signs with time are going to be broken or blistering plaster, dark damp patches on walls and flaking or bubbling paintwork.

If neglected for a while, a leaking roof can cause wet rot in the timbers of your roof. While it doesn't spread into the brickwork, wet rot can cause your roof timbers to become structurally compromised, and in the worst outcome you could even need to replace the whole roof - extremely costly! A distinctive musty odour, a "spongy" feel to your rafters and signs of a black fungus, could all signify the presence of wet rot.

The means of prevention can be fairly basic, for example repointing brickwork, inspecting piping for leaks and cleaning and checking your guttering and roof for leaks. As part of a complete damp proofing package, your local Derry damp proofing specialist will check out all of these aspects.


Condensation Damp Derry UK (028)

Super easy to identify and a cause of damp in a lot of Derry properties, condensation is very common. Minute droplets of water appear on cooler surfaces when warm, humid air comes into contact with these surfaces. In places where high humidity is present, as in: kitchens, boiler rooms and bathrooms, it arises due to poor ventilation.

Basic solutions to prevent condensation involve wiping away any water droplets whenever they appear and ensuring there is enough ventilation in the problem areas. The necessary steps might involve the installation or upgrade of air bricks, cooker hoods and extractors, with the intention of redirecting moist air to the outside of your home in Derry.

A detailed damp proofing survey from a trustworthy Derry specialist could also find circumstances which contribute to the situation by sucking in damp air from outside. To satisfactorily control condensation problems, airflow has to be properly regulated. A professional Derry damp proofing technician will gladly offer solutions and advice in this regard.

Damp Proofing Quotes in Derry Northern Ireland


Ever since 1875, a damp proof course has been installed as standard in all homes built in the United Kingdom. It's quite possible that you might not have one fitted if your house in Derry was built before this year. If you're experiencing rising damp in a home constructed after this date it may be that your damp proof membrane has been damaged somehow.

If you suppose that you may have rising damp, rotten or crumbling skirting boards, white powdery deposits being discovered on floor surfaces or forming on walls and "tide marks" on walls, are good indications that you may be right. It's feasible that you might have a rising damp issue if you have seen one or all of these in your property.

Rising Damp Derry Northern Ireland

Remedying rising damp problems can be as simple as checking your property's outside walls and seeing if you can see a damp proof course. To be certain of a satisfactory measure of protection the damp proof membrane must be above ground level by at least 150 millimetres. You could dig away the surrounding ground to generate this gap if it is currently not sufficient, or you could install a higher DPM if the first option isn't possible.

If this isn't the cause of the problem and your damp proof course is in fact correct, there may be more serious issues to deal with caused by the moisture coming up from the ground beneath, up through your flooring, and into the walls.

Using a number of different methods, damp proofing technicians in Derry will quickly identify and resolve your rising damp problems. If you've got a somewhat older property with no damp proof membrane or it is damaged over a considerable area, a damp proofing cream (such as Permaguard or Dryzone) can be injected into your outside walls. This entails drilling holes at intervals into your wall's mortar joint and the special cream injected with a nozzle to plug the spaces behind the brickwork down to below ground level.

If the damp proof cream isn't suitable, or the damage is too extensive to your DPM, a brand new damp proof course may have to be installed. This is taking repair work to the extreme, but it might be the only remedy for your damp issues.

Painting with a waterproof (bitumen based) latex emulsion, is another potential option for less severe areas of membrane damage. As this will be applied beneath your existing floor coverings, carpeting, tiles and wooden flooring must be lifted and moved before this procedure can begin. Also used as part of the "tanking" procedure to create a waterproof space, this is an especially effectual solution in cellars. Before the bitumen paint has dried completely, your Derry damp proofing specialist may recommend the use of building paper (a special foil backed membrane), for additional protection.

Tanking: In areas of a property which are below ground, for example cellars or basements, "tanking" is a process where any surfaces that are exposed are painted with a waterproof coating. All wall coverings and plaster must be removed and the pertinent surfaces correctly prepared before any work begins, as this coating must be applied at the base level of walls and floors. Once this coating has been applied, it should be permitted to dry thoroughly before replastering the wall surfaces and decorating on top of it. This is an exceptionally disruptive process as it has to be applied to a whole ground floor or basement level of a property, and it is wise to obtain more than one specialist opinion about whether this is really the only treatment for your rising damp.


To help ease issues with condensation, you can always try dehumidifiers, which for removing moisture from the air, are very effective. The main disadvantage with dehumidifier use in attempting to stop mould and damp is that they merely alleviate the cause of the damp, not cure it. An experienced damp proofing company in Derry will be glad to advise on the best solution if you are suffering from mould or damp in any area of your house.


As with just about any project, the best recommendations for a specialist come from family and friends. If possible you should always try to get at least two or three different estimates from a range of companies, and before hiring any particular damp proofing providers, you can ask to see professional memberships and accreditations, as proof of their credibility.

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

If your chosen Derry damp proofing providers are members of the PCA or DPA they'll be properly qualified and have the appropriate experience to offer a first class service for your damp proofing issues. Any remedial work carried out by one of their members also comes with a guarantee.
