Damp Proofing London Colney Hertfordshire (AL4)


  • Penetrating Damp

  • Condensation

  • Rising Damp


The following paragraphs describe what causes such damp issues in London Colney, and the various ways of preventing and resolving them.


Penetrating damp can be the result of a whole host of external factors for example: loose or cracked roof tiles, damaged guttering, cavity wall problems and cracks in brickwork. From within, cracked shower trays, overflowing basins or bathtubs and leaky or burst pipes, can trigger penetrating damp. If left unresolved, peeling paintwork, blistering or broken plaster and damp dark patches on walls, will be the noticeable outcome of water soaking into the woodwork and walls.

If left untreated for an extended period of time, a leaky roof can cause wet rot to develop in your roof timbers. Whilst it can't spread into brickwork, wet rot can cause your roof timbers to become structurally unsound, and in a worst case scenario you may even need to replace the whole roof - extremely costly! Wet rot can be recognised by the appearance of black fungus on your woodwork and a spongy feel to the timber, together with a distinctive musty smell from the decaying timber.

Simple steps like repointing brickwork, cleaning and checking your rain gutters and roof for leaks and examining pipes for leaks, can be the basic preventative measures. A professional damp proofer in London Colney will check all these areas to help avoid any future complications, as an integral part of resolving your issues with damp.


Condensation Damp London Colney UK (01727)

One of the most common forms of damp in London Colney homes, condensation is very easy to spot. Tiny water droplets appear on cold surfaces when they make contact with warm, humid air. In places where high humidity is present, such as: kitchens, bathrooms and boiler rooms, it's often caused due to poor ventilation.

Basic strategies to reduce condensation include wiping away any droplets as soon as they form and making sure you have adequate ventilation in the trouble spots. Redirecting moist air to the outside of your home in London Colney, by upgrading or fitting air bricks, extractor fans and cooker hoods, will help you to remedy this annoying problem.

The best way to establish the key circumstances that give rise to the situation, is to have a detailed damp proofing survey done by a professional London Colney specialist. In some cases moist air can be sucked in from the outside, plainly making matters worse. The best way to successfully minimise condensation is to regulate airflow properly, and your local London Colney damp proofing company will offer advice and guidance on how this can be achieved.

Damp Proofing Quotes in London Colney Hertfordshire


A damp proof course has been compulsory on homes built in the United Kingdom since 1875. You might not have a damp proof course installed on your home in London Colney if it was built earlier than this. If your property was constructed after this date, but you are still experiencing rising damp, it may be that your damp proof membrane or course has been compromised.

If you believe that you may have rising damp in your home, tide marks on walls, crumbling or rotten skirtings and a white powdery deposit forming on walls or being found on floor surfaces, are good signs that you may be right. Although the existence of these is not conclusive, they're all clear indications of rising damp issues.

Rising Damp London Colney Hertfordshire

Dealing with rising damp issues can be as easy as checking your property's exterior walls and seeing if you can see a damp proof course. It ought to be 150mm above the level of the ground for satisfactory protection. If you discover this space doesn't exist, you can dig away the soil to increase it, or if this process isn't feasible, a higher DPM will have to be put in.

If this is not the cause of the problem and your DPM (damp proof membrane) is in fact correct, there could be more serious issues to resolve caused by the moisture coming up from the ground beneath, through your floor, and into the walls.

London Colney damp proofing experts will swiftly be able to determine the cause of your rising damp, and employing a number of different techniques will soon fix the problem. Older houses which either don't have a DPM, or have a compromised one which is damaged over a wide area, can have a damp proofing cream (such as Permaguard or Dryzone) injected into the outside walls. This special cream is injected with a nozzle into holes drilled evenly along the wall's mortar joint, and before the cream sets it turns into liquid and soaks into the surrounding brickwork creating a barrier that is water-repellent.

In situations where damp proofing injection cream isn't an appropriate remedy, or where your membrane is too severely damaged, installing a complete new damp proof course may be neccessary. Though this is obviously a fairly extreme approach, it could be the only way to solve your rising damp issues successfully.

For minimal areas of damp course damage, yet another potential solution would be to coat with a waterproof (bitumen based) latex emulsion paint. Carpeting, tiles or wood flooring must be lifted prior to work being done, as it is applied underneath your current floor coverings. This is particularly effectual in cellar areas as part of the "tanking" procedure to make a room which is watertight. Before the bitumen coating has dried completely, your London Colney damp proof expert might suggest a layer of building paper (a special foil backed membrane), for added protection.

Tanking: In basements, cellars and below ground areas of a house, "tanking" is the process where surfaces that are exposed are covered in a watertight coating. As this waterproof coating must be applied to the base surface of walls and floors, all wall covering and plaster must be taken off before work begins, and the surfaces in question prepared correctly. You can replaster and decorate over the top of it, as soon as the coating has dried completely. This is an exceedingly disruptive job as it has to be applied to a whole ground floor or basement level of a building, and it is preferable to obtain more than one expert's opinion on whether this is the only remedy for your rising damp issues.


Dehumidifiers are an effective way of reducing the moisture content in the air, hence for condensation issues they can help quite a bit. The fact that these gadgets basically mask the cause of the damp and don't cure it, is the main disadvantage with dehumidifier use. To get the best advice if you are suffering from damp or mould in any part of your house, you should contact a certified damp proofing specialist in London Colney.


The best recommendations for professionals with regards to home improvement projects are generally friends and family. Always get at least two or three different quotes from various companies, and if you have any doubts you should ask to see evidence of professional membership certificates and qualifications, before hiring any damp proof services.

Look out for technicians holding the CSRT (Certificated Surveyor in Remedial Treatments) or the CSTDB (Certificated Surveyor of Timber and Dampness) accreditations, or local companies who are members of the PCA (Property Care Association) or the Damp Proofing Association (DPA).

You can be sure that your damp proofing provider is well qualified and has the appropriate working experience to carry out a high quality damp proof service, if they've got membership of either the PCA or DPA. Any damp proofing work accomplished by any one of their members is also guaranteed.

Obtaining recommendations from friends and relatives is invariably a good idea when looking for a professional contractor for your project or undertaking in London Colney.

Friends and Family Recommendations for Damp Proofing

Getting this form of testimonial from a relative or friend will also give you information about the contractor's punctuality and reliability, and if things went wrong, how they were dealt with and how swiftly they were put right. You can also get a notion of how the price charged for the work compared to the initial quote they were given, which, unless they offer a guaranteed price promise, is frequently tricky to get directly from the contractors.

You can rely on your friends and relations to be truthful and honest, hence they should be your first point of reference in regards to advice. You may well discover that they will be reluctant to discuss them, if they have had a poor experience in dealing with a certain company or contractor. It is frequently the case that some people will be more than willing to recommend a decent contractor, but less likely to discuss an inferior one, and rather than 'besmirch' a a far from perfect business they've had dealings with in the past, they might offer an alternative company instead.
