  • Penetrating Damp

  • Condensation

  • Rising Damp


The next paragraphs describe what may cause such damp issues in London Colney, and the different ways of preventing and resolving them.


A few of the exterior factors that may cause penetrating damp in a property include: broken roof tiles, defective guttering or drainpipes, damaged or porous brickwork and blocked cavities. Internally, damaged shower trays, burst or dripping water pipes and overflowing bathtubs or sinks, can contribute to penetrating damp. Visible signs such as peeling or bubbling paintwork, blistered or broken plaster and damp, dark patches on walls, all suggest that these issues have been left uncontrolled.

If you have a leaking roof that has been neglected for a while, the timbers of your roof can be stricken with wet rot. Even though brickwork isn't impacted by wet rot, the timbers on your roof can be seriously damaged, and the whole roof may need to be replaced if it becomes structurally unsound. If any of the timbers on your roof feel "spongy" to touch, and a black fungus starts appearing the wood, you may have wet rot in your roof structure. Should you encounter any of these wet rot signs, it's imperative to address the problem promptly to obviate further structural damage and the potential for a expensive roof replacement.

The measures for prevention can be quite basic, for instance cleaning and checking your rain gutters & roof for leaks, repointing dodgy brickwork and examining piping for leaks. As part of a complete damp proofing package, your local London Colney damp proofing company will check all of these areas.


Condensation Damp London Colney UK (01727)

One of the most common forms of damp within many properties in London Colney, condensation is very easy to spot. When cool surfaces make contact with humid, warm air, minute water droplets appear on those cold surfaces. It is an issue due to poor ventilation in places where high humidity is present, i.e. kitchens, bathrooms and boiler rooms.

Wiping away any water droplets that form, and making certain you've got adequate ventilation in the affected areas, are among the simplest solutions to such problems. This may involve the installation or upgrade of air bricks, extractor fans and cooker hoods to help remove the damp air outside of the building.

With some homes damp air is drawn in from outside, plainly making the situation even worse. And the most effective way to establish the key things that bring about the problem, is to have an in-depth damp proofing survey done by a reliable London Colney company. An effective way to successfully control condensation is to regulate circulation and airflow correctly , and your local London Colney damp proofing technician will offer advice and guidance on how this can best be achieved.

Damp Proofing Quotes in London Colney Hertfordshire


A damp proof course or membrane has been compulsory on homes constructed in Great Britain since 1875. You might not have a damp proof course installed on your house in London Colney if it was built earlier than this. It's possible that your damp proof course or damp proof membrane may have been damaged in some way if you are experiencing rising damp problems in a home built after this year.

It can be difficult to identify rising damp, but some giveaway indications are; "tide marks" on walls, crumbling or rotten skirtings and white powdery deposits being found on floor surfaces or appearing on walls. It's plausible that you might have a rising damp problem if you have noticed one or all of these in your property.

Rising Damp London Colney Hertfordshire

Fixing rising damp issues can be as straightforward as checking your home's exterior walls to see if you can spot a damp course. For adequate protection it needs to be 150mm (about six inches) above ground level. Where you find this gap doesn't exist, you could dig the soil away to increase it, or if this process isn't plausible, a higher DPM will need to be put in.

If this isn't the cause of the problem and your DPM is installed and in order, there could be more problematic issues to resolve caused by the moisture coming up from the ground beneath, through your floors, and into the walls.

London Colney damp proofing technicians will quickly be able to figure out the causes of your rising damp, and using a number of different procedures will soon eliminate the problem. Older homes which either don't have a DPM, or have a compromised one that is damaged over a substantial area, can have a damp proof cream (such as Dryzone or Permaguard) injected into the external walls. Holes are drilled at intervals along the brickwork, and a nozzle is used to inject the special cream, which then penetrates into the surrounding brickwork before curing to create an effective, horizontal waterproof barrier.

If the damp proofing cream isn't sufficient, or the damage is too extensive to your DPM, a new damp proof course might need to be put in. Regrettably this is the most extreme of repair works, but it might be the only solution to your rising damp problems.

Another possible solution for minimal areas of damage may include painting with a bitumen based, waterproof latex emulsion coating. Tiles, laminate flooring or carpeting must be lifted before any work can be carried out, because it's applied beneath your floor coverings. This is particularly effective in cellars as part of the tanking process to create a watertight room. Before the bitumen paint has has dried out completely, your London Colney damp proofing expert may advise laying building paper (a specialist foil backed membrane), for added protection.

Tanking: The process of covering exposed surfaces with a waterproof paint in a below ground area such as a basement is referred to as tanking. This should be applied on the base surface of walls and floors, therefore any wall covering and plaster must be removed and the relevant surfaces properly prepared before work commences. You can replaster the wall surfaces and decorate on top of it, after the coating has completely dried. This is a very disruptive process because it must be applied to an entire ground floor or basement level of a property, and it is recommended that you obtain more than one expert's opinion about whether this is really the only treatment for your rising damp.


Dehumidifiers are an effective way to remove moisture from the air, hence for problems with condensation they can be of help. The fact that these products basically alleviate the cause of the damp and don't cure it, is the main downside with dehumidifiers. A certified damp proofing specialist in London Colney will be happy to offer advice on possible solutions if you're experiencing dampness in any area of your home.
