  • Penetrating Damp

  • Condensation

  • Rising Damp


These 3 primary kinds of damp are explained in depth in the following paragraphs, together with strategies for prevention and resolution, should you discover them in your house in Castlereagh.


A few of the exterior factors that may cause penetrating damp in a property include: blocked cavity walls, damaged or porous brickwork, damaged guttering or downpipes and cracked roof tiles. Inside a house, overflowing bathtubs or sinks, damaged shower trays and leaking or burst pipework, can contribute to penetrating damp. Visible signs like flaking paintwork, damp, dark patches on walls and blistered or broken plaster, all suggest that these issues have been left uncontrolled.

If you have a leaking roof and it has been neglected for quite some time, it can cause wet rot in your roof timbers. This could prove very costly, because if worse comes to worst your roof timbers become structurally unsound, meaning that you will need a new roof. If your roof timbers feel "spongy" to the touch, and a black fungus appears on the wood, you almost certainly have wet rot in your roof structure. When you spot any of these signs of wet rot, dealing with the issue promptly is essential to prevent further structural harm and the potential need for costly roof replacement.

Some simple maintenance can help prevent this, such as: repointing dodgy brickwork, examining piping for leaks and cleaning and checking your roof & gutters for leaks. If you get hold of a knowledgeable damp proofing service in Castlereagh, they will check all these areas, and put a plan together for both resolving your dampness issues and forestalling further occurrences.


Condensation Damp Castlereagh UK (028)

There are several things that cause dampness, but condensation is among the most common and easily noticed. When a cool surface comes into contact with warm, moist air, water collects as small droplets upon that surface. Inadequate ventilation in places with high humidity, for instance in bathrooms, boiler rooms and kitchens, is the most frequent explanation for condensation.

To lower the impact of this issue there are two basic steps that you can take. You can wipe away any droplets the instant they arise, and you can ensure that there is adequate ventilation in areas that most suffer from condensation. The necessary steps may require the updating or installation of extractor fans, cooker hoods and air bricks, with the purpose of redirecting damp air outside of your property in Castlereagh.

By doing a comprehensive damp proofing survey, an experienced Castlereagh company will find any places where moist air is sucked in from outside, simply exacerbating the problem. To effectively minimise condensation problems, circulation and airflow must be regulated properly. A competent Castlereagh damp proofing specialist will be able to offer advice and solutions to accomplish this in your home.

Damp Proofing Quotes in Castlereagh Northern Ireland


Homes built since 1875 in the UK have been required to have a damp proof course or membrane to be fitted as standard. If your house was built before this period it's perfectly possible that you may not have this installed. If your property was constructed after this date, but you're still suffering with rising damp problems, it could be that your DPM has been damaged.

If you suppose that you might have rising damp in your home, "tide marks" on walls, white powdery deposits appearing on walls or being discovered on floor surfaces and crumbling or rotten skirting boards, are good indications that you might be correct. While the existence of one or more of these is not conclusive, they are all indications of rising damp problems.

Rising Damp Castlereagh Northern Ireland

Dealing with rising damp problems can be as straightforward as checking your external walls to see if you can spot a DPM. For adequate protection it ought to be 150 millimetres (approximately 6 inches) above ground level. If you find this space does not exist, you could dig away the ground to increase it, or if this process isn't feasible, a higher damp proof membrane (DPM) will have to be put in.

You might have more serious issues if you learn that your DPM (damp proof membrane) is fine, and it may be that the moisture is rising from the ground, through your flooring, and into the walls, which will be even more of a concern.

Castlereagh damp proofing experts will quickly be able to determine the explanation for your rising damp issues, and using a number of different techniques will soon eliminate the problem. Older properties which either don't have a damp proof course at all, or have a compromised one which is damaged over a significant area, can have a damp proof cream (such as Dryzone or Permaguard) injected into the external walls. This special cream is injected with a nozzle into holes drilled evenly along the mortar course, and before the cream cures it turns to liquid and penetrates into the surrounding brickwork creating a barrier that is repellent to water.

If the damp proof cream isn't sufficient, or the damage is too extensive to your DPM, a new damp proof course may have to be installed. Whilst this level of repair work is a pretty drastic way to solve damp issues, it might be the only effective solution when all is said and done.

Damp Proofing Specialists Castlereagh (BT6)

The application of a waterproof (bitumen based) latex emulsion, is another possible option for less severe areas of membrane damage. This will be applied underneath your current floor coverings, so tiles, carpeting and wood flooring will have to be lifted prior to work being done. In cellar areas this is an especially efficacious treatment, and will form an integral part of the "tanking" procedure which is used to make rooms watertight. Your Castlereagh damp proof specialist might recommend the laying of building paper (a specialist foil backed membrane) before the bitumen paint has completely dried out, additional protection in those trouble spots.

Tanking: "Tanking" refers to a waterproofing technique specifically for basements, cellars or subterranean spaces, involving the application of a special type of watertight paint to exposed surfaces. The effectiveness of this method requires the removal of all plaster and wall coverings first, to allow direct application of the waterproof coating on the base of walls and floors, thereby establishing a robust barrier against moisture. The key to this process is allowing the coating to dry thoroughly before proceeding with any replastering or decorative work. Although tanking involves treating the entire lower level of a building and can be quite extensive, it's beneficial to consult with various damp proofing experts to decide if it's the most suitable solution for your rising damp issues, as there may be other less invasive but equally effective options.


To help ease condensation problems, you could try using dehumidifiers, which for removing moisture from the air, are very efficient. Due to the fact that dehumidifiers primarily cover up the cause of the damp and not cure it, there are issues with this solution. To get the most reliable advice if you're suffering with damp in any part of your house, you can speak to a professional damp proofing company in Castlereagh.
