Damp Proofing Harrow Greater London (HA1)


  • Penetrating Damp

  • Condensation

  • Rising Damp


Below you will find information about what could be causing damp problems in your home or business in Harrow, and precisely how you can set about fixing them.


Penetrating damp in the home can be attributable to different external factors for instance: loose or cracked roof tiles, damaged guttering, cracks in brickwork and cavity wall problems. Inside a building, overflowing sinks or baths, damaged shower trays and burst or leaking pipes, can contribute to penetrating damp. If water is allowed to continue seeping into the woodwork and walls, the obvious signs with time are going to be broken or blistering plaster, damp dark patches on walls and peeling paintwork.

Wet rot can arise in the timbers of your roof if you have a leaky roof that's left untreated over a period of time. Though it doesn't spread into your brickwork, wet rot can cause the timber in your roof to become structurally unsafe, and in the worst outcome you could even need to get a new roof - very costly! If black fungus starts to appear on any woodwork and the timber in your roof feels "spongy" to the touch, you could have problems with wet rot.

The measures for prevention can be pretty basic, for instance cleaning and checking your guttering and roof for leaks, repointing brickwork and examining pipes for leaks. If you employ the expert services of a certified Harrow damp proofing specialist, they'll check all these factors as a part of your all round damp proofing arrangement.


Condensation Damp Harrow UK (020)

Very easy to identify and a contributing factor to damp in many Harrow properties, condensation is very common. Tiny droplets of water appear on cooler surfaces when they come into contact with warm, humid air. It is often caused because of inadequate ventilation in places where high humidity is present, i.e. bathrooms, boiler rooms and kitchens.

Wiping up any droplets that appear, and making certain that there's sufficient ventilation in the worst affected areas, are amongst the most basic answers to such problems. Redirecting moisture laden air outside of your property in Harrow, by fitting or upgrading cooker hoods, air bricks and extractors, will help you to resolve this issue.

There may be issues with sucking in moist air from outside, and by conducting a detailed damp proofing survey a specialist in Harrow will be able to find areas that bring about the problem. Airflow needs to be regulated properly to successfully control condensation, and a reliable damp proofing specialist will be able to offer advice and solutions on this subject.

Damp Proofing Quotes in Harrow Greater London


A damp proof course or membrane has been installed as standard on houses built in the UK since 1875. You might not have a damp proof course installed on your home or property in Harrow if it was built earlier than this. If you are experiencing rising damp in a property constructed after this date it's possible that your damp proof course or damp proof membrane has been damaged in some way.

It can be tricky to identify rising damp, but some giveaway signs are; "tide marks" on walls, a white powdery deposit being discovered on floor surfaces or forming on walls and crumbling or rotten skirting boards. Although the existence of one or more of these is not conclusive, they're all clear indications of rising damp issues.

Rising Damp Harrow Greater London

Resolving rising damp problems can be as simple as checking your outside walls and seeing if you can spot a DPM. To be sure of a satisfactory measure of protection the DPM needs to be above ground level by no less than 150 millimetres. If this is not the case you might be able to dig away the ground to create this gap, or if this isn't possible, you can put in a damp proof membrane (DPM) higher up.

You could have more serious issues if you find that your DPM (damp proof membrane) is fine, and it may be that the moisture is seeping up from the ground, through your flooring, and into your home's walls, which can be an even more disturbing situation.

Harrow damp proofing specialists will swiftly be able to figure out the causes of your rising damp, and using a number of different techniques will soon fix the problem. Older houses which either have no damp proof course, or have one that is damaged over a wide area, can be treated with a damp proof injection cream such as Permaguard. 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 turns into liquid and soaks into the adjoining brickwork forming a barrier that is water-repellent.

In instances where damp proofing injection cream isn't a satisfactory solution, or when your membrane is too severely damaged, putting in a brand new damp proof course might be neccessary. Regrettably this is the most drastic of repair works, but it may be the only solution to your rising damp.

Painting with a bitumen based, waterproof latex emulsion, is yet another possible option for less severe areas of damp course damage. Wood flooring, carpets or tiles must be lifted prior to work being carried out, since it is applied beneath your existing floor coverings. This is particularly effective in cellar areas as an integral part of the tanking process to create a room that's watertight. For extra protection in such trouble spots, your Harrow damp proof technician may advise the laying of building paper (a special foil backed membrane) before the bitumen paint has dried completely.

Tanking: In areas of a property that are below ground, such as basements, tanking is the process where surfaces that are exposed are covered in a waterproof coating. Because this watertight coating has to be applied to the base surface of floors and walls, any plaster and wall coverings must be taken off before any work can begin, and all surfaces correctly prepared. As soon as this coating has been put on and dried, it's then possible to replaster any walls and decorate over it. This is an exceptionally disruptive process since it needs to be applied to an entire basement level or ground floor of a building, and it's recommended that you get more than one expert's opinion about whether this is the only resolution to your damp problems.


Dehumidifiers are an effective way of lowering the moisture content in the air, hence for issues with condensation they can be of help. The drawback with the use of dehumidifiers in endeavouring to reduce damp and mould is that they merely hide the cause of the damp, not cure it. To obtain the most reliable advice if you are suffering with mould or damp in any part of your home, you can speak to an experienced damp proofing specialist in Harrow.
