There are many sources of dampness that affect our properties.
The most common forms of dampness tend to be Rising Damp (discussed here), Penetrating Damp, Condensation, and leaking rain water.
Rising Damp is the transfer of moisture from the soil to the foundations of a wall.
The absorption continues into the bricks via Capillary Action.
The Rising Damp carries natural ground salts such as nitrates, chlorides and sulphur, which can sometimes be seen on the surface of the plaster as white crystals.
Few structural problems are more worrying for homeowners than rising damp.
Fixing it can be expensive, and leaving it alone results in mould and severe structural damage.
But rising damp is also often misdiagnosed, sometimes accidentally, sometimes by cowboys overcharging for a damp problem which may have a far simpler cause.
If you understand how rising damp occurs and how to spot it, you're less likely to have to wool pulled over your eyes by unscrupulous damp "experts".
Bricks are porous, which allows them to "breathe", releasing moisture during the day and absorbing it during night.

The DPC prevents water from the ground rising up inside the wall, where it can damage internal finishes and cause decay to timber in contact with the damp masonry.
The most common reason for failure is old age but often building works like new patios or extensions can compromise the DPC: This is called bridging because moisture can now reach the unprotected wall.
The end result is damaged paint, wallpaper and flaking plasterwork.
More serious problems such as DRY and WET ROT can follow.
DampWorks solves the problem by injecting a new damp proof course; our chemical injection process is safe and environmentally friendly and cures within the masonry wall to form an IMPERVIOUS BARRIER TO RISING DAMP.

Tim Pye— Can't recommend this company enough Great team of guys who know what their doing
With the help of our experienced team, you can protect your property from experiencing the effects of rising damp.
By placing a chemical barrier of DPC (damp proof course) inside the walls, CPM Waterproofing Services Ltd protects your property from moisture passing into the interior spaces of your home in Kingston, Surrey.
This works as a long-term prevention for moisture decay, therefore preventing timber decay and structural damage, such as rising damp, dry rot, and wet rot.
The treatment involves a concentrated thixotropic silane/siloxane cream being introduced into the wall to form a barrier against rising damp.
A dampness problem of any type isn't good news but rising damp can be particularly troublesome which is why it has such a bad reputation.
If you have a modern home, you'll usually have the safety net of a damp-proof course (DPC) in place to limit the damage, but if you have an older property, built before 1875, this protective barrier is unlikely to be in place.
Building work or altering the ground level can sometimes damage the damp proof course, or raising the floor level above the protective layer can stop it from doing its job too.

By recommending modern, environmentally safe and approved solutions for rising damp, condensation, dry rot or any alternative form of building defect, Damp Solutions On Site can help you to save valuable time and money.
Our surveyors are experienced in diagnosing condensation and identifying the conditions that are leading to the problem.
Usually simple advice on methods of providing a more balanced regime of heating and ventilation is sufficient to resolve the issue.
Where rising damp is diagnosed it is vital that the source of moisture is identified before any work starts.
Treatment work, such as a Damp Proof Course, will only prevent further moisture rising from the ground, so we will only recommend this solution where it is clear that this will resolve the problem completely.
Timkon Services offer a 20 Year Guarantee Certificate for both Rising Damp Treatment & Timber Treatment and this can be insurance backed for a period of 10 Years.
The benefit of our Guarantees may be assigned up to 3 months after completion of sale or new ownership following payment of the re-assignment fee.
Thereafter the Guarantee will become null and void.
Have you ever wondered whether your guarantee will be honoured in the event your contractor ceased to trade?
Hopefully, your chosen contractor will always be there to respond to any problems that may arise over the period of their guarantee and meet the remedial costs accordingly.
Condensation usually occurs when the moisture in the property, e.g. the humidity and vapour from hot showers & baths or drying your washing, is coupled with a lack of ventilation i.e. you are not opening windows, there is a lack of an extractor fan etc.
Penetrating damp may be due to a leaking roof, missing roof tiles, poorly maintained or damaged plumbing or some other structural defect where water soaks into the structure.
Rising damp, however, is caused by a building's structure soaking up groundwater in a capillary action.
