What causes damp in homes?
There are four main types of damp that can severely damage homes, these are rising damp, penetrating damp, condensation and underground water ingress, luckily here at watertight homes, we have the skills and knowledge to remedy them all.
Rising damp is usually caused by rising groundwater through capillaries in masonry. This is a well-known problem especially in older properties, this is why most new builds are now built with a DPC. However rising damp can still occur in these properties mostly due to a faulty or non-existent DPC, in this case, a DPC must be installed to stop the rising damp from occurring.
Often misdiagnosed for another cause of damp, our team thoroughly investigates until we are certain of the root cause of the damp to ensure it doesn’t cause further damage and unnecessary cost.
Penetrating damp is caused by water infiltrating the building or property through an external wall, this mainly occurs either due to water entering through a defect in a building or when external bricks or stone walls have degraded over time to the point they have become porous. Once the external bricks have become porous they allow water ingress to pass through the external wall into the property. Penetrating damp is usually the main cause of damp in a property.
Damp caused by condensation occurs when moist air in the home comes into contact with cold surfaces such as walls, windows, mirrors etc. the air can’t control the moisture and water starts to form, this type of damp can also be found in the corner of rooms and inside and behind furniture. Usually, poor ventilation in the property causes this type of damp as the moisture has nowhere to go.
Compared to modern buildings, older properties were not designed to combat dampness and stop excess build-ups of water or moisture, therefore they are more likely to suffer from severe and continuous damp related problems. Regular building maintenance will help prevent damage caused by damp however a lot of damp related issues are also caused by the improper maintenance of properties by individuals who don’t know how to properly treat and diagnose the damp.
Frequently Asked Questions
Damp proofing is a protective measure used to describe the methods and tools used to prevent damp from penetrating and being absorbed through the walls and foundations of buildings to cause dampness in the interior of the building or property. Damp related issues are one of the most common issues encountered in homes.
The majority of damp related problems are caused by either rising damp or penetrative damp. Rising damp is the movement of water upwards from the ground in the lower sections of walls. Penetrative damp is caused by excess water penetrating through an external wall into the property. Penetrative damp is the most common form of damp and mostly occurs due to defects and damage to a buildings roof coverings, renderings, guttering and downpipes.
The time period between damp proofing and redecorating can vary depending on the type of paint being used. Typically non-vinyl emulsion can be used after 3 – 4 weeks. wall covering such as vinyl and washable paper and paints should only be applied when the walls are fully dry. As a general rule, it should take a full month for each 25mm thickness of the wall, however, the drying time also depends on other factors such as room temperature, the extent of the damp that has been fixed and the ventilation of the room.
If the damp in your home has been caused by condensation then a dehumidifier will extract moisture from the air and release warm air balancing out the moisture levels in your home, potentially solving your damp problem.

Types of damp proofing
As one of the most frequent and frustrating problems affecting homeowners in the UK, it’s no surprise that when symptoms of rising damp, penetrative damp, and condensation arise the need for accurate and high-quality solutions becomes of the utmost importance.
While the different types of damp can often show the same symptoms, each one requires a different approach and tools in order for them to be rectified. When talking about damp proofing most would assume that a damp proof course fixes all issues and while it does tackle problems associated with rising damp there are other techniques that better help prevents the other types of damp from recurring like damp proof membrane.
Damp Proofing Course
A damp proof course (DPC) is a damp proofing solution used to treat rising damp. There are different methods that can be used to repair and install damp proofing courses, the most common of which is the damp proofing injection.
Damp-proof courses are only effective in the treatment of rising damp and do not help in the treatment of other types of damp. It should be noted that rising damp is often misdiagnosed by untrained tradespeople so we recommend only getting evaluations from trusted sources such as ourselves who have years of knowledge in the identification and treatment of rising damp.
Damp Proofing Membrane
A damp proof membrane is a high-density polyethene membrane that is impervious to water infiltration and any pollutants that may be present. As a result, a damp proof membrane is an excellent material for treating damp problems like penetrating damp and rising damp.
After the source of the water, ingress has been corrected, the membrane is fastened to internal walls, and its rough surface creates a cavity that allows moisture to evaporate from the wall behind it. These membranes are frequently employed as part of a cavity drainage system in structural waterproofing projects in basements and cellars.
Excess water on your windows and black mould on your walls and window frames are signs that your home is moist due to condensation. This is a regular occurrence in humid spaces like the bathroom and kitchen, where water vapour (steam) is abundant.
Opening windows, keeping lids on boiling pots, or closing the door when taking a bath can all help to prevent condensation. You may also require a dehumidifier to help better ventilate your home.
