  • Penetrating Damp

  • Condensation

  • Rising Damp


The next article describes the sources of such damp issues in Letchworth, and the various methods of preventing and resolving them.


Penetrating damp in the home can be caused by various external factors for example: broken or loose roof tiles, unsound brickwork, cavity wall issues and damaged guttering. Inside your Letchworth home, it can be the result of cracked shower trays, overflowing baths or sinks and leaky or burst pipes. If water is allowed to continue soaking into the woodwork and walls, the visible signs in time are going to be damp dark patches on walls, broken or blistered plaster and peeling or bubbling paintwork.

If you have a leaky roof and it has been left untreated for some time, it can cause wet rot in the timbers of your roof. Even though it is fortunate that wet rot does not have an impact on brickwork, in the worst case scenario, you may need to get a new roof if your roof timbers become structurally unsound. Wet rot can be identified by the appearance of black fungus on your woodwork and a spongy feel to the timber, along with a unique musty smell from the decaying wood.

You shouldn't fret however, because to stop these problems from occurring, a few straightforward steps like repointing brickwork, cleaning and checking your roof and guttering for leaks and examining piping for leaks should aleviate such concerns. A knowledgeable Letchworth damp proof service will check these areas to help prevent any future complications, as an element of solving your dampness issues.

A common form of damp in many homes in Letchworth, condensation is super easy to spot. Small droplets of water form on cooler surfaces when moist, warm air makes contact with these surfaces.

Damp Proofing Quotes in Letchworth Hertfordshire


Ever since 1875, a damp proof course or membrane has been compulsory in all houses constructed in Great Britain. You may not have a damp proof course on your property in Letchworth if it was constructed prior to this period. If you're experiencing rising damp in a home constructed after this date it is possible your damp proof membrane or course has been damaged somehow.

Although hard to distinguish, rotten or crumbling skirting boards, a white powdery deposit appearing on walls or being found on floor surfaces and "tide marks" on walls, are all giveaway clues that you might have rising damp. If you notice or think that you may have any of these issues, it's possible that you have a problem with rising damp.

Rising Damp Letchworth Hertfordshire

Dealing with rising damp problems can be as straightforward as checking your property's outside walls and seeing if you can see a damp proof course. It ought to be 150 millimetres above ground level for satisfactory protection. If this is not the situation you may be able to dig the ground away to create this gap, or if this is not plausible, you could put in a damp proof course higher up.

If this isn't the problem and your DPM (damp proof membrane) is installed and in order, there might be more challenging issues to deal with caused by the dampness coming up from the ground beneath, through your floors, and into your walls.

Using a number of different techniques, damp proofing professionals in Letchworth will swiftly identify and eliminate your rising damp problems. A damp proofing cream (such as Permaguard) can be carefully injected into your wall if you've got a somewhat older property with no damp proof membrane, or one that is damaged over a substantial area. This special cream is injected with a nozzle into evenly spaced holes drilled along the mortar course, and before the cream can set it turns to liquid and soaks into the surrounding brickwork forming a barrier that is repellent to water.

In instances where damp proofing cream injection isn't a suitable remedy, or where the damp course membrane is too seriously damaged, installing a brand new damp proof course could be neccessary. Whilst this level of repair work is a fairly extreme way to solve damp issues, it could be your only solution in the final analysis.

Another option for minimal areas of membrane damage may include painting on a layer a bitumen based, waterproof latex emulsion coating. Because this is going to be applied beneath your floor coverings, carpets, tiles and laminate flooring will need to be lifted and removed before this process can commence. Also used as part of the tanking process to create a waterproof space, this is an especially effectual treatment in basement areas. Your Letchworth damp proof expert may suggest the laying of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried out, additional protection in such troublesome areas.

Tanking: In cellars and below ground areas of a property, tanking is the process where any exposed surfaces are painted with a watertight coating. All wall covering and plaster must be removed and the pertinent surfaces correctly prepared before the commencement of any work, as this coating must be applied at the base level of walls and floors. As soon as this paint has been applied, it should be allowed to dry out thoroughly before replastering and decorating on top of it. This is a very disruptive process since it has to be applied to an entire ground floor or basement level of a building, and it's wise to obtain more than one expert's opinion on whether this really is the only remedy for your rising damp.


Condensation problems can certainly be improved by the use of dehumidifiers, which are an effective way to remove moisture from the air. Because dehumidifiers just cover up the cause of the damp and not cure it, there are drawbacks to this option. If you're suffering with damp in any area of your home in Letchworth, you can get hold of a certified damp proofing company for the most reliable advice.
