In Harrow buildings there are three major problem areas of how damp can affect your property:

  • Penetrating Damp

  • Condensation

  • Rising Damp


These three key forms of damp are described in greater detail in this article, together with strategies for prevention and resolution, in case you discover them in your house in Harrow.


Typical external factors that can lead to penetrating damp include: defective guttering, broken or loose roof tiles, cavity wall issues and unsound brickwork. Inside, it can be triggered by dripping or burst pipes, overflowing basins or baths and cracked shower trays. If left to continue leaking these issues allow water to soak into the woodwork and walls, which with time lead to dark damp patches on walls, blistered or broken plaster and flaking paintwork.

Wet rot can occur in your roof timbers if you've got a leaking roof that's been neglected over a long period of time. Though it is lucky that wet rot doesn't have an impact on brickwork, in a worst case scenario, you may need to get a new roof (extremely expensive!) if your roof timbers become structurally unsound. If black fungus starts to appear on your woodwork and the timber in your roof feels "spongy" to the touch, you might have a case of wet rot.

Preventative maintenance can be fairly basic, such as repointing dodgy brickwork, cleaning and checking your gutters and roof for leaks and inspecting pipes for leaks. If you employ the services of a knowledgeable Harrow damp proofing provider, they will check all these aspects as a part of your complete damp proofing package.


Condensation Damp Harrow UK (020)

Very easy to spot and a cause of damp in many Harrow homes, condensation is extremely common. Small droplets of water appear on colder surfaces when moist, warm air makes contact with them. Inadequate ventilation in areas with high humidity, for instance in boiler rooms, bathrooms and kitchens, is the most frequent reason for condensation.

To stop condensation problems, easy strategies include making sure that there is adequate ventilation in the worst affected areas, and wiping away any droplets of water as they form. This might call for the upgrading or installation of air bricks, cooker hoods and extractor fans to help remove the humid air outside of the building.

A detailed damp proof survey by a trusted Harrow company might also find things which give rise to the situation by drawing in moist air from outside. To successfully control condensation problems, airflow must be regulated properly. A reliable Harrow damp proofing technician is well qualified to offer solutions and advice to accomplish this in your home.

Damp Proofing Quotes in Harrow Greater London


Houses constructed since 1875 in the UK have required a damp proof course or membrane to be installed as standard. If your home or property was built before this time it's conceivable you may not have one installed. If you're suffering with rising damp in a home constructed after this time it might be that your damp proof course or damp proof membrane has been somehow or other.

Although difficult to distinguish, a white powdery deposit forming on walls or being found on floor surfaces, rotten or crumbling skirtings and tide marks on walls, are all giveaway clues that you might have rising damp. Although the existence of one or more of these is not conclusive, they are all indications of rising damp problems.

Rising Damp Harrow Greater London

Remedying rising damp problems can be as straightforward as checking your external walls and seeing if you can see a damp course. To be sure of an adequate measure of protection the DPM must be above ground level by at least 150mm (around 6"). You could dig away the surrounding soil to create this gap if it is currently not enough, or you can put in a higher damp proof membrane if the first option isn't plausible.

If this isn't the root cause of the problem and your damp course is in fact correct, there might be more challenging issues to resolve caused by the dampness coming up from the ground, through your floors, and into the walls of your property.

Using a range of techniques, damp proofing professionals in Harrow will quickly identify and resolve rising damp. If you have an older home with no damp proof course or it is damaged over a substantial area, a damp proofing cream can be carefully injected into your outside walls. This cream is injected with a special nozzle into evenly spaced holes drilled along the wall's mortar course, and before the cream sets it diffuses into the surrounding brickwork forming a barrier that is water-repellent.

If the damp proofing cream isn't appropriate, or the damage is too extensive to your membrane, a brand new damp proof course might need to be installed. Unfortunately this is taking repair work to the extreme, however it may be the only resolution to your damp issues.

For minimal areas of damp course damage, yet another possible solution would be to coat with a waterproof (bitumen based) latex emulsion. Laminate flooring, carpeting or tiles must be lifted before any work can be done, as it is applied underneath your existing floor coverings. Also used as a part of the tanking procedure to create a waterproof room, this is an especially effectual treatment in basements. Before the bitumen paint has completely dried, your Harrow damp proofing expert may suggest the application of building paper (a specialist foil backed membrane), for additional protection.

Tanking: The process of covering exposed surfaces in a waterproof paint in a below ground area such as a basement or cellar is referred to as tanking. Any wall coverings and plaster must be taken off and the surfaces in question properly prepared before work commences, because this coating must be applied at the base level of floors and walls. As soon as the paint has been put on and dried, it is then possible to replaster and decorate over the top. You must invariably obtain more than one expert opinion on whether this is the only remedy for your damp problems, as this is a highly disruptive job as it must be applied to a whole basement level or ground floor of a building.


To help ease condensation issues, you can try using dehumidifiers, which for reducing the moisture content of the air, are fairly effectual. The main problem with dehumidifiers in trying to prevent damp and mould is that they basically hide the cause of the damp, don't get rid of it. If you're experiencing dampness in any area of your home in Harrow, you should speak to a professional damp proofing specialist for the best advice.


As with any home improvement project, the best recommendations for a local specialist come from friends and relatives. Before signing up to any damp proof services, you should always see if you can get at least 2 or 3 quotes from different Harrow companies. If you've got any doubts about any damp proofing company you should ask to see qualifications and professional memberships.

Watch out for membership of and qualifications from organisations such as the Damp Proofing Association or the PCA (Property Care Association), or contractors holding the Certificated Surveyor of Timber and Dampness or the Certificated Surveyor in Remedial Treatments accreditations.

Membership of the PCA or DPA guarantees your chosen damp proofing provider is properly qualified and has acquired the appropriate experience to perform a first class damp proofing service. In addition, it offers guarantees on any remedial work carried out by one of their members.
