  • Penetrating Damp

  • Condensation

  • Rising Damp


These three key kinds of damp are described in more detail in this article, along with recommendations for prevention and resolution, if you should discover them in your property in Harlesden.


Penetrating damp can be caused by various external factors such as: broken or loose roof tiles, defective drainpipes or gutters, unsound brickwork and cavity wall issues. Inside a building, it can be triggered by overflowing baths or basins, burst or leaky water pipes and damaged shower trays. If left to continue leaking these elements enable water to seep into walls and woodwork, which over time lead to blistered or broken plaster, flaking paintwork and dark, damp patches on walls.

You could get wet rot developing in the timbers on your roof, if you have a leaking roof, and it has been neglected for some time. This could prove extremely expensive, because if worse comes to worst the structural integrity of your roof timbers could be compromised, with the result that you are going to need a new roof. If your roof timbers feel "spongy" to touch, and a black fungus appears on the woodwork, you might have a case of wet rot in your roof structure. Upon detecting any of these wet rot indicators, it's vital that you take swift action to avert further harm and the likelihood of a pricey roof replacement.

Preventative maintenance can be basic, such as inspecting pipes for leaks, cleaning your rain gutters & roof and checking for leaks and repointing brickwork. If you employ the services of a professional Harlesden damp proofing firm, they will check all these elements as part of your overall damp proofing program.


Condensation Damp Harlesden UK (020)

A common form of damp in many houses in Harlesden, condensation is super easy to spot. When cool surfaces make contact with warm, humid air, small droplets of water form on those cold surfaces. It often manifests due to poor ventilation in places where there's high humidity, i.e. bathrooms, kitchens and boiler rooms.

There are two straightforward ways of managing condensation issues, and these are making sure that trouble spots have good ventilation, and wiping water droplets away as they appear on surfaces. To help redirect the humid air from your home, you might need to fit or update extractor fans, cooker hoods and air bricks.

A damp proofing survey by a credible Harlesden company might also find things which bring about the issue by drawing in damp air from outside. An expert in this industry will be able to offer advice, information and solutions on this matter, because to make sure condensation issues are controlled, airflow and circulation within the home must be effectively regulated.

Since 1875, a damp proof course has been compulsory in all homes constructed in the United Kingdom. You might not have a damp course installed on your home in Harlesden if it was constructed earlier than this. It's possible that your damp proof course might have been damaged if you are experiencing rising damp issues in a home built after this date.

If you believe that you might have rising damp in your home, tide marks on walls, crumbling or rotten skirting boards and a white powdery deposit being discovered on floor surfaces or appearing on walls, are good signs that you might be correct. While the existence of these isn't conclusive, they're all indications of rising damp issues.

Rising Damp Harlesden Greater London

Resolving rising damp problems can be as easy as checking your property's external walls to see if you can spot a DPM. To be certain of an adequate measure of protection the damp course should be above ground level by no less than 150mm. Where you find that this gap does not exist, you could dig away the soil to increase it, or if this process is not feasible, a higher DPM will have to be put in.

You may have more challenging issues if you discover that your DPM (damp proof membrane) is fine, and it could be that the moisture is seeping up from the ground, through your flooring, and into the walls, which is going to be even more worrying.

Using a number of different procedures, damp proofing experts in Harlesden will swiftly detect and eliminate rising damp. If you have a somewhat older property with no damp proof membrane or one that's damaged over an extensive area, a damp proofing cream can be injected into your wall. This cream is injected with a special nozzle into evenly spaced holes drilled along the wall's mortar course, and before the cream can set it turns into liquid and soaks into the adjoining brickwork forming a barrier that is water-repellent.

If the damage to your membrane is too severe, or if damp proofing cream injection isn't an appropriate solution, you might need to put in a new damp proof course. This is the most drastic of repair works, but it might be the only solution to your rising damp.

For smaller areas of membrane damage, yet another potential option would be to coat with a waterproof (bitumen based) latex emulsion. This is applied underneath your current floor coverings, so wood flooring, carpets and tiles must be lifted prior to work being done. This is especially effective in basement areas as part of the tanking procedure to create a room that's watertight. Before the bitumen coating has completely dried, your Harlesden damp proof specialist might suggest the application of building paper (a foil backed specialist membrane), for additional protection.

Tanking: To waterproof cellars or below-ground areas, "tanking" is used, which entails applying a special waterproof paint to the exposed surfaces. This process necessitates first removing all existing wall coverings and plaster to ensure the waterproof coating is applied directly to the walls and floors' base. This step is essential to create a barrier that is impermeable to moisture. After application, it's crucial to let the coating dry completely before undertaking any replastering or decorating. Tanking is a thorough method, impacting the entire lower part of a building, so it's advisable to consult multiple damp proofing experts to ascertain if tanking is the optimal solution for your rising damp problems, as there might be less invasive yet equally effective alternatives.


Condensation issues can definitely be helped by means of dehumidifiers, which are an efficient way of lowering the moisture content in the air. The main drawback with dehumidifier use in seeking to stop damp is that they only mask the cause of the damp, don't get rid of it.

Fumigation is a much more invasive treatment, but for large infestations, it is frequently the best option.

Prevention is also key in avoiding future woodworm infestations. This can be achieved through frequent inspections, maintaining good humidity levels and ventilation, and treating any existing woodworm as soon as it's identified.

Regularly inspecting the premises is an effective way to spot infestations of woodworm early on, enabling speedy action to be taken to minimise damage.
