According to the English Housing Survey, there are almost 1 million dwellings in England that are currently suffering from damp issues. Of those, 225,000 suffer from a type of damp called penetrating damp, and, a further 7 million dwellings are outlined as being particularly vulnerable to penetrating damp due to the construction method of the building and bricks.
The NHS cites that a damp home can lead to respiratory problems, respiratory infections, allergies, or asthma and can also affect the immune system. Getting on top of your damp can have a crucial impact on your and your family’s health.
However, that’s not all. If left untreated or unchecked for long enough, the structure of your property could become compromised, and penetrating damp is one of the most structurally damaging types of damp.
What is penetrating damp?
If you have damp patches on your walls at random heights (ie, not just at the ground level), especially straight after raining then its likely that penetrating damp is the culprit. Penetrating damp is, quite literally, when rain and water can penetrate through your walls and into your house. You can spot it as dark patches on the outside of the building, or in some cases,
There are a few causes from issues with your cavity wall, through to cracks leading to water coming through, but a common cause is through having inadequately protected brickwork. Of the 7 million solid wall properties in the UK, many of them have porous brick, and in the UK where it rains on 156 days a year, the brick can get overwhelmed.
Stage 1 of dealing with your penetrating damp is to survey the scene and work out the exact cause. Have a look and see if any visual defects can be found like cracks, mortar issues or broken gutters. You might have to use a professional to see up high. If you see no defects in this way, you should move to protect your brickwork to give better waterproofing. A telltale sign if this is needed is if your damp shows up in heavy rain due to saturation. Exterior protective paints for residential, such as Stormdry, provide great waterproof protection of the brickwork, whilst allowing the wall to breathe from the inside.
Stormdry coating is a clear, breathable, water-repellent treatment for brick, concrete and stone walls. It is supplied in the form of a deeply penetrating cream that is applied to the wall surface. Once Stormdry has been applied to the wall surface in a single coat, wait 24 hours and it will permeate deeply before curing to form a water-repellent barrier for a BBA approved 25 years.
It also may be a good idea to proactively protect your house with waterproof coatings as they can give the following benefits:
- Increased thermal protection. With 35% of a homes energy being lost through the walls, a dry brick radiates less heat than a wet brick
- Improved performance of your cavity wall insulation as it is not becoming damp
- Improving flood resistance of masonry
- Protecting mortar and masonry for a long time
- Increase the value of your house
