What Causes Damp?

causes-damp-detail

If you’re experiencing damp in your home, it’s a lot more common than you think. Even in buildings that are known to be dry, you might be surprised to know that these walls can hold a serious amount of water in the materials they’re made from. A lot of the time this doesn’t cause any hassle, however, if damp does take hold, it can cause a lot of problems. Both from an aesthetic point of view and also becoming hazardous to your health.

Damp can be easily spotted in your home. There are certainly several signs to look out for. First of all, you may have noticed a musty smell. You might have found wet patches on your walls, ceilings and floors. Or possibly the paint has blistered. Or your walls are bulging. You might see a white substance on your brickwork. And certainly, if you’ve spotted black mould on any surfaces or fabrics like your curtains, this will give you a definite indication that you’ve got damp that needs treating.

What Causes Damp? Signs of dampness in the corner of a ceiling.

So if this is the case in your home, it’s time to tackle the damp and find out exactly where it’s coming from. Here are some possible causes that could be contributing to your problem:

Condensation

You may find that this happens more regularly in autumn, winter and spring. It’s actually caused by poor ventilation and/or a lack of heating. So kitchens, utility rooms or humid bathrooms can be prime examples if there’s nowhere for the humidity to escape from.

Condensation occurs when the moisture produced by cooking, cleaning, breathing and washing can’t be dispersed from the property due to a lack of adequate ventilation. Moisture is retained in the atmosphere until the air temperature cools. And it’s at this point the airborne moisture condenses onto the wall surfaces, which can result in unsightly mould growth in your home.

Traditionally, properties used to be less ‘airtight’ and were difficult to heat. However, draughts would dilute the high humidity so condensation was less likely to happen. Unfortunately, our modern lifestyles have contributed to the problem in lots of ways. Smaller rooms and reduced air leakage of modern homes, plus the fact that many properties remain empty during the daytime and energy saving measures such as reduced ventilation and double-glazing, all combine to provide the perfect environment for condensation to rear its head.

And as warm, moist air from kitchens and bathrooms travels to colder rooms, such as bedrooms, it then forms condensation on cold unventilated surfaces, such as external walls, within wardrobes and behind furniture etc.

Construction moisture

Have you had building work completed in your home recently? Concrete, plaster and mortar can hold a lot of water and take a long time to dry out. And if your builder hasn’t put proper protection in place for when it rains, you may find that water can get in and cause damp.

Leaking pipes and roofs

When it comes to your roof or your pipes, even the smallest leak can create a major problem. And it’s not always at the site of the leak. You might find that it can cause damp problems further away. And don’t forget your gutters too. They can easily become blocked, with pools of water unable to escape. Any entry of water will, at some point, create a problem with moisture which will then cause water damage to your home. Which is why it’s very important to keep your property in a dry and waterproof condition and adequately maintained.

Rain penetration

If you’ve got problems with your brickwork or rendering, it can become a prime target for major damp issues. Any broken or missing pointing, cracked or missing rendering, frostbites to the brickwork etc. will cause a collection of rain water and ultimately you’ll soon be looking at a damp problem.

Rising damp

More than just the name of a TV programme, rising damp can cause real problems in your home. This is where water seeps in from the wet ground. You can easily spot it by the horizontal tidemark that can appear on your wall. This will happen in old properties built without the original damp proof course or in any property where the original damp proof course is failing. However, the old horizontal slate damp proof courses can also break during the property movements – all likely to be caused by passing time, increased traffic and subsidence.

There are other causes of damp that can easily happen in your home from spillages and instances where water simply can’t get away. Don’t let it become an issue in your home.

What are the best ways to get rid of mould?

signs-of-rising-damp

Mould and mildew are types of fungus that appear as a result of high moisture levels. One of the biggest causes is bathroom condensation although mould can be an indication of rising damp too. Extensive rainfall can result in increased humidity or there could be a weakness in external walls or guttering. It’s essential to identify the type of damp so it can be treated quickly and effectively. Children and the elderly are most at risk, particularly those with skin conditions or respiratory issues. It’s important to get rid of any mould if it appears as spores can spread swiftly.

  • Use a specialist mould cleaning spray to remove the mould. Follow the instructions for use as per the packaging.
  • Clean mould using a disposable cloth. Keep the doors of the room you are cleaning shut as the spores from the mould will become airborne when cleaning.
  • Repeat this in all the rooms affected, throwing away the cloth each time or you could spread the mould.
  • If there is no re-occurrence, anti-mildew paint can be used on affected walls.
  • An electric dehumidifier might help with short-term mould prevention.

To ensure mould does not return to your property, you need to identify the cause. The issue might be the result of condensation, which can be remedied by tackling humidity levels ventilating the property and using an extractor fan in the kitchen whilst cooking. For blocked guttering, leaking pipes behind a wall and rising damp, contact the experts. Damp Control specialists Schrijver has a chemical-free solution that’s also eco-friendly.

Rising Damp, Fact or Myth?

Our industry sometimes comes under attack with attempts to discredit many companies selling and installing damp proofing treatments or products. This is understandable because the problem of structural damp has many causes, some of which can be interrelated. This means that the reasons for damp being evident can be easily misdiagnosed and the wrong method of management recommended.

You may have even heard some say that “true rising damp is a myth”. This statement is often attributed to Stephen Boniface, who was a former chairman of The Royal Institution of Chartered Surveyors.

However, he clarified this statement later in a post made on the Surveying Property website saying;

“Whilst I have often been quoted as stating ‘rising damp is a myth’ the only time I have ever said that phrase (or similar) is once when delivering a paper at a conference and then using the intake of breath as a cue to then develop the argument further and explore the issue of damp. In other words, I used the phrase provocatively (it usually worked).”

In many situations, it is clear that the signs of damp such as rotting skirting boards, stained walls, blistering paper or paintwork, black mould, rotting floor boards or the unpleasant odour are caused by moisture finding its way into your walls. If this water is rising from the ground then rising damp is what you have to deal with.

Damp Proofing Methods

The options you have to consider are:

  • Replacement of a physical damp proof course
  • Land drainage
  • Injection of chemical damp proof course
  • Damp-proofing rods
  • Electrical-osmotic systems
  • Natural evaporative system

The first two options are often impractical or impossible, the second two involve the use of harsh chemicals and usually require lots of disruptive and expensive internal re-plastering and decorating work. Electrical systems have little evidence to support them.

10 Ways to Identify Penetrating Damp

apr17-image-01-768x400-1

Penetrating damp, or rain penetration as it can be referred to happens when water finds its way inside a property from the outside. This might be through walls, windows or doors although roof defects can also be a cause. Penetrating damp is more likely to occur in older properties as well as those by the sea or open to the elements.

It’s important to identify penetrating damp and any defects swiftly as it can lead to bigger problems such as a dry rot infestation. Damp can also cause respiratory problems particularly in the young and the elderly. Here are ten ways to identify if your property has penetrating damp:

  • 1. Musty smells with black mould or mildew on walls or skirting boards.
  • 2. Damp patches or water drips on walls, ceilings and floors, especially those that worsen in heavy rain. This includes on the upper floors (rising damp only affects lower levels).
  • 3. Cold rooms.
  • 4. Blistered, disintegrating or stained plaster.
  • 5. Rotting floors or skirting boards – a sign of wet rot.
  • 6. Faulty joints between windows and walls and badly fitted door frames.
  • 7. Defective plumbing issues or burst water pipes.
  • Defective plumbing or bust water pipes
  • 8. Brickwork, render or pointing decay; especially in older properties.
  • Brickwork, render or pointing decay; especially in older properties.
  • 9. Broken guttering or leaky rainwater pipes.
  • 10. A leaking roof or broken roof tiles.

When you identify penetrating damp in your property and the causes too, you will ensure the problem can be treated effectively and in the right way. Damp issues are normally eliminated, with a barrier between the damp and the wall, although damp specialists Frank Schrijver has a chemical-free eco-friendly solution using natural ventilation – the Schrijver System.

Guaranteed for life, it’s the greener option to traditional methods.

No additional decorating is required as all the work is undertaken outdoors. A series of small, handmade elements are fixed to the outside wall of your property – just above skirting board level. Essentially the system works as dry air flows constantly from the outside into the handmade elements through an opening. This causes moisture from the wall interior to be deposited within the element, therefore, taking it outside. This results in lower humidity levels and continuous protection.
