How To Treat Damp Walls Internally
–
Improving the ventilation e.g. add kitchen and bathroom fans where necessary. Allow the fan to run for a long period of time to allow any moisture to be cleared from the room. Use a Condensation Mould Kit to remove any mould from walls and surfaces. Once the mould treatment has been applied then this can be painted with a damp seal which ensures that the staining will not seep through the emulsion paint. Improve the heating of the property and insulate the cold walls.
Damp in walls can also occur from rising damp. If groundwater rises up the inner walls of the property this can cause damage to skirting boards, plaster peeling off walls as well as black mould growth. Treatment for rising damp is usually done by one of two methods: Either by having a chemical damp proof course or by having a damp proof membrane fitted.

How do you permanently get rid of damp walls?
Condensation Treatment – For condensation, there are a number of simple steps you can take to reduce damp. Improving the ventilation of a room is essential for allowing the condensation to escape before it can gather and cause mould growth. Open windows regularly and move furniture away from walls to allow air to circulate more effectively around the room.
What is the main cause of damp on internal walls?
Cold Spots Resulting in Condensation – One of the most common causes of damp on internal walls is condensation. What happens is that condensation forms when warm moist air within a room touches a cold internal wall or surface. The warm moist air coos down, and condenses back into water. Wall insulation allows the home to breathe, and is permeable to water vapor. In the same time, the insulation allows air and moisture to pass from one side to another
Can wet walls be fixed?
Solve the damp problem – Treating the walls is a big part of clearing a damp problem but it is even more important to handle the underlying cause too. If the issue is condensation, then consistent heat and ventilation are key. If it is rising damp, a new damp proof course and special replastering may be needed.
What are the symptoms of living in a damp house?
How do molds affect people? – Exposure to damp and moldy environments may cause a variety of health effects, or none at all. Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin.
- Some people, such as those with allergies to molds or with asthma, may have more intense reactions.
- Severe reactions may occur among workers exposed to large amounts of molds in occupational settings, such as farmers working around moldy hay.
- Severe reactions may include fever and shortness of breath.
In 2004 the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.
- In 2009, the World Health Organization issued additional guidance, the WHO Guidelines for Indoor Air Quality: Dampness and Mould,
- Other recent studies have suggested a potential link of early mold exposure to development of asthma in some children, particularly among children who may be genetically susceptible to asthma development, and that selected interventions that improve housing conditions can reduce morbidity from asthma and respiratory allergies.
A link between other adverse health effects, such as acute idiopathic pulmonary hemorrhage among infants, memory loss, or lethargy, and molds, including the mold Stachybotrys chartarum has not been proven. Further studies are needed to find out what causes acute idiopathic hemorrhage and other adverse health effects.
Will dehumidifier get rid of damp?
Do Dehumidifiers Stop Damp? – To put it simply the answer is no, however, if you are looking to reduce high humidity and the chance of condensation occurring then dehumidifiers can be a good solution. To get to the bottom of the problem it is important to understand why there are humidity levels in the first place. Other problems related to damp such as rising damp and penetrating damp are something that a dehumidifier cannot deal with. Having structural defects at your property will need a professional to provide an inspection at the property and identify what remedial action needs to be taken to resolve the problem. Typical structural problems can be any of the following:
Having a damaged or indeed no damp proof course in place- if a property does not have an adequate damp proof course in place it can be one of the causes of rising damp to occur as there will be no protection for water rising up from the ground. Damaged rainwater goods- If your gutters are clogged or damaged then this will mean, especially during periods of heavy rainfall, that water will not drain away and could potentially penetrate through to the inner walls of the property. Leaking pipes- If there are leaking pipes at the property then this will mean that has the potential for dampness to occur and should be rectified by a qualified plumber.
As you can see that there are many different causes of damp in houses and if the damp problem isn’t diagnosed or treated in a sufficient amount of time then the building could suffer from severe structural issues.
What happens if you sleep in a damp room?
Yes, if you have damp and mould in your home you’re more likely to have respiratory problems, respiratory infections, allergies or asthma, Damp and mould can also affect the immune system.
How do you tell if a damp wall has dried?
Try the foil test – If you’re not sure of the cause of a damp patch on a wall, try the foil test. Dry the wall surface with a fan heater, then tape some kitchen foil tightly over the damp area. If the surface of the foil is wet after 24 hours, you have condensation.
Can damp break walls?
Yes, dampness can cause structural damage to a house if left unaddressed over a prolonged period of time. Dampness refers to the presence of excess moisture or water in building materials, such as walls, floors, and foundations. It can occur due to various reasons, such as leaks in plumbing, rainwater infiltration, condensation, or rising damp from the ground.
Does opening windows reduce damp?
Rising Damp – Rising damp is less likely to occur on or around your windows as damp will only rise to approximately 1 metre above the ground. While damp cannot be reduced by opening windows, it can help to reduce the humidity levels in your property to make sure that condensation is not a common occurrence.
Does putting the heating on help damp?
Using your heating to keep a property warm is essential and can help to slow down the spread of damp. Condensation dampness is caused by water from the air soaking into cold walls, so maintaining heat in the property will reduce the amount of condensation that will form.
Can you get rid of damp completely?
8 Damp Preventing Tips – The most effective way to remove condensation damp is to correctly ventilate your property. However there are every-day things you can implement to help; 1) Wipe down windows and sills every morning.2) Deal with steam from cooking.3) Get rid of bathroom moisture.4) Don’t overfill wardrobes & cupboards.5) Keep your house warm.6) Insulate.7) Make sure the extractor fans are on.8) Don’t hang clothes to dry inside. If we don’t expel all the excess moisture we create out of the home, it will be left lurking inside, usually ending up in the coldest places of the house such as windows, doors etc. This will ultimately lead to damp and damage to your health and your property.
The best way to get rid of damp is to prevent it starting in the first place and the best way to prevent it is to ensure your home is consistently well ventilated. A good habbit to get into is to open the windows but keep doors closed to prevent spores spreading to other areas of the house. However this measure will only go so far, the best ventilation is of course a fully fitted, intelligently designed system.
EnviroVent has a range of ventilation systems designed to prevent condensation and mould problems. By fitting a whole house ventilation system and correctly ventilating your home, condensation dampness will disappear and your damp areas will dry out, ready for redecoration.
The best way to control condensation in your home is by installing a ventilation system such as a Positive Input Ventilation (PIV) system, or by installing a Mechanical Ventilation Heat Recovery (MVHR) system which is the best system for ensuring desired levels of humidity and good indoor air quality.
The whole house ventilation system will effectively remove condensation dampness and leave you with a healthy indoor environment every day of the year.
