Damp Proofing Monmouth Wales (NP25)


  • Penetrating Damp

  • Condensation

  • Rising Damp


We'll explore these 3 significant types of damp problems, and come up with tips on how to prevent them and resolve them, if they come about.


Penetrating damp in structures can be attributable to numerous external factors for instance: porous brickwork, broken roof tiles, damaged drainpipes or gutters and blocked cavities. Inside your home, it can also be a result of leaking or burst pipes, overflowing bathtubs or sinks and damaged shower trays. Visible signs like blistering or broken plaster, dark, damp patches on walls and peeling paintwork, all point to the fact that these problems have been left unresolved for some time.

If you have a leaking roof that's been neglected for a while, the timbers of your roof can be affected by wet rot. Though it doesn't spread into your brickwork, wet rot can cause the timber in your roof to become structurally unsafe, and in a worst case scenario you could even need to replace the entire roof - very expensive! An unfamiliar musty smell, a "spongy" feel to your woodwork and signs of a black fungus, could all indicate the presence of wet rot. Upon identifying any of these wet rot signs, it is crucial to take action immediately to avert further harm and the potential expense of a roof replacement.

The means of prevention can be fairly basic, for example examining pipes for leaks, repointing brickwork and cleaning your gutters & roof and checking for leaks. A professional damp proofer in Monmouth will check all of these areas to help avoid any further complications, as part of solving your issues with damp.


Condensation Damp Monmouth UK (01600)

A common form of damp in Monmouth properties, condensation is extremely easy to identify. When colder surfaces make contact with moist, warm air, small droplets of water appear on those cold surfaces. It often manifests because of inadequate ventilation in places where high humidity is present, i.e. boiler rooms, kitchens and bathrooms.

Among the more simple answers to condensation include wiping water droplets away as they form, and making sure that the worst areas have sufficient ventilation. You may need to install or update air bricks, cooker hoods and extractors, so as to redirect excess moist air from your property in Monmouth.

Occasionally damp air is drawn in from the outside, simply making things even worse. And the best way to identify the key things that exacerbate the situation, is to have an in-depth damp proofing survey done by a professional Monmouth damp proofing specialist. Airflow needs to be properly regulated to successfully control condensation problems, and a certified damp proofing specialist will offer advice and solutions on this subject.

Damp Proofing Quotes in Monmouth Wales


Since 1875, a damp proof course has been compulsory in all houses constructed in Great Britain. If your home or property was built before this period it's conceivable you may not have this installed. If you are experiencing rising damp in a house constructed after this date it might be that your damp proof membrane has been somehow or other.

Rising damp can be hard to distinguish, but some areas to keep an eye out for are; a white powdery deposit being discovered on floor surfaces or appearing on walls, rotten or crumbling skirting boards and "tide marks" on walls. It is plausible that you might have a rising damp issue if you have spotted one or more of these in your home.

Rising Damp Monmouth Wales

The initial step towards managing your problems with rising damp should simply be to check whether or not you have in fact got a damp course on the outside walls of your property in Monmouth. To be sure of a satisfactory degree of protection the damp proof course ought to be above ground level by at least 150mm (approximately 6"). You can dig the surrounding soil away to generate this space if it is currently not enough, or you could install a damp proof course higher up if the first option is not plausible.

You may have more serious issues if you discover that your damp course is okay, and it may be that the dampness is rising from the ground, through your flooring, and into your property's walls, which is going to be an even more worrying scenario.

Using a variety of methods, damp proofing experts in Monmouth will swiftly detect and resolve rising damp issues. If you've got a somewhat older home with no DPM or one that's damaged over a significant area, a damp proofing cream (such as Dryzone or Permaguard) can be carefully injected into your external walls. Evenly spaced holes are drilled at intervals in the mortar joint, and a nozzle is used to inject the special cream, which then diffuses before curing to create an effective waterproof barrier.

In cases where damp proofing injection cream isn't a suitable remedy, or when your DPM is extensively damaged, installing a complete new damp proof course could be neccessary. Although this is naturally a fairly drastic approach, it may be the best way to remedy your damp issues effectively.

Painting with a bitumen based, waterproof latex emulsion, is yet another potential solution for less severe areas of membrane damage. Carpets, laminate flooring or tiles will need to be lifted before any work can be undertaken, as it is applied underneath your current floor coverings.

Before the bitumen paint has has dried out completely, your Monmouth damp proofing specialist might suggest the application of building paper (a special foil backed membrane), for extra protection.

Tanking: "Tanking" is a specific method used for making basements, cellars or other below-ground areas waterproof, involving the application of a special watertight paint on exposed surfaces.

Once applied, it's essential to allow the coating to dry completely, a process that can take some time, before proceeding with replastering and any decorative finishes.

Therefore, it's advisable to consult with several damp proofing companies to determine if tanking is indeed the best solution for your specific rising damp issues. There may be alternative, less disruptive methods available that could be equally effective. Given the scale and potential disruption of tanking, it's important to consider all options and understand the long-term implications of such a treatment on your property.
