The Facts About Damp, Mould and Condensation

The cause of damp is often quite obvious in the symptoms the different forms of this moist present; however, this isn’t always the situation. Usually moist is identified due to the”musty” odor, mold or damp stains which look inside the home. The most common form within houses in this nation is condensation.

Insufficient”Breathability” and a build-up of water vapor in our buildings not only cause rot, damp and structural failure, but it is also a major contributor to sick building syndrome. Additionally, it has been heavily linked to the growth of allergies and asthma in this country.

Rising Damp – In brief, this can be water soaked up from the floor by capillary action and is just an issue when a building has no Damp Proof Course (D.P.C), very common in older buildings(pre-1930), or even when the D.P.C was bridged or damaged. Rising damp only rises about 1m above ground level because of gravity and the capillary forces.

The way to rising damp – is usually to inject a chemical D.P.C.. This might have to be done to various locations and can sometimes have to be done internally in addition to externally.

This type of work carries varying guarantee periods but normally between 20 – 30 years. Penetrating Damp – Water penetrating through the walls or roof. This is where water flows into a building through a fault such as round a chimney stack or windows. Examples of this could also be missing roof tiles or lack of mortar between brick courses. Also, look for leaking or missing drainpipes as these can result in water soaking all of the ways through the wall. This type of difficulty can be made apparent internally by the appearance of isolated damp patches.

How do I stop penetrating damp? – In some cases, these internal patches will be only rectified by creating proper outside fixes, by way of example, re-pointing. But if this issue is more prevalent internally this will lead to the higher moisture content in plasterwork, decorative finishes and the home generally. This may then require a more permanent solution. To prevent this continuing to be an issue, some kind of outside weather protection, like an expert render system or resin based transparent coating would need to be implemented.

Condensation – Usually more noticeable in winter, because the construction is cold and because windows have been opened less moist air can’t escape. When warm moist air produced by ordinary household activities hits a cold surface it condenses into water droplets i.e. an external wall or window condensation occurs. This problem is”homemade”. Household activities like Cooking, Breathing, Bathing or drying clothing to list a few all are a significant source of water vapor inside the house.

Preventing condensation

Try to not wash clothing in your property. If this is not practical, keep the doorway of the room where clothes are draining close. Open the windows, since this will enable the moisture out of the clothing to escape and will prevent it from moving around your home. – If you use a tumble dryer make sure that it is vented to the exterior or use a condensing dryer. – When cooking the kitchen should be ventilated. Utilize an extractor fan if you have one or open a window. Keep the kitchen door closed. – Cover boiling pans with pan – this may save money on your fuel bills as well as reducing moisture. Click here to learn more

Ventilation – Ventilation in the home, if sufficient, allows moisture to escape to the outside. Modern living has caused a drop in natural venting. We’ve got over recent years installed double glazed windows and doors introduced everyday showers and shut-off open fireplaces. The typical household in the united kingdom can place as much as 15 gallons of water to its atmosphere on a daily basis!

The simplest and most affordable form of venting is to make a window open whenever possible. In housing built before 1875, they were often built without a D.P.C. and hardly any protection externally from penetrating moist.

Dehumidifiers – A popular solution to condensation and damp problems is a dehumidifier. These come in a variety of shapes and sizes which range from small units that will keep a closet or wardrobe dry to large units which are effective at drying out anything from an area to a complete house. Most versions have a flat switch that can turn the dehumidifier away and sound an alarm when the tank is full.

Insulation – condensation occurs on cold spots, so in the event that it is possible to warm up the chilly spots you will help control condensation. Insulating your loft, external walls and draught-proofing doors and windows should reduce the number of cold spots and create your home cheaper to heat. Insulated nicely, they’ll remain warmer for longer, reducing the risk of water vapor condensation and therefore reducing the conditions that are ideal for mold growth.

Heating – attempt to avoid having cold areas within the house. It’s better to heat the entire house at a lower temperature than it would be to heat one room at a very large temperature. When you get condensation and mold forming, it is often not the area that you are producing the moisture from e.g. kitchen or bathroom but in a room which you don’t often use e.g. spare bedroom. This is probably because this room is not usually heated. Try heating all of the rooms regularly. Ensure that you are using the heating system and its controls economically since this will also help save you money. Persistent heating will eventually enable warmth to penetrate walls and ceilings that will help to remove the water vapor. During the cooler months always work to maintain the inside temperature at 5º C higher than the temperature outside. Visit PuroClean today.

Moisture – Reducing the amount of moisture in your house will cut down the amount of condensation.

Mould – Is a type of fungi that can grow in a range of areas inside the house but only when there is a damp present. Even though there are lots of different types of mold they all thrive on high humidity and if growing provides off particles which can lead to allergic reactions. If humidity drops abruptly these particles can maintain their millions and can cause sneezes. Mold growth in buildings has been significantly linked with asthma and other respiratory conditions especially in children or vulnerable adults. Mold spores will only increase in clean water rather than the contaminated water from rising or penetrating damp.

Mould usually can be eliminated with a diluted solution of bleach, after carefully the manufacturer’s security guidance. Always test a tiny discreet area first before applying it to the entire area. After applying to the affected surface leave it for approximately 20 minutes then soda with water. – In more severe cases, to kill and remove mould, wipe down walls and window frames with a fungicidal wash. Follow the manufacturer’s directions carefully. – Dry clean any clothes or affected material and shampoo any carpeting. Disturbing mold spores by vacuuming or cleaning may increase the chance of respiratory issues. – Mould eradications kits supply the very best approach to completely remove mould. Kits are available through our offices. – After treatment, re-decorate with a good grade fungicidal paint to help prevent recurrence.
