Rising damp
If damp spots, mould, or loose stucco are visible on the bottom of the wall on the ground floor, it is almost certainly rising damp. This is groundwater that works its way up through the foundation through capillary action to the facade of the house. This can happen because the water barrier between the foundation and facade is damaged or even completely missing. For this, the wall is injected in some cases, this means that a chemical agent is sprayed into the wall, creating a flood barrier. Chemicals do break down over time, however, having this become a recurring problem when solved with chemicals.

With high humidity, condensation problems arise. Condensation is the precipitation of moisture against cold surfaces when it cannot find a way out. Think of fogged windows, damp spots on the wall and the formation of mold in the form of black-gray dots. Because a lot of domestic moisture is produced in the house (showering, cooking, washing, breathing, drying clothes, etc.) it is important to ventilate well, especially in wet areas such as the bathroom. In some cases it is advisable to install ventilation grilles or you can opt for mechanical ventilation (keep in mind that this also results in extra energy costs).

Penetrating damp
If the outer wall is damaged, it can cause heavy damp issues (rain water that enters through the outer wall). You often see this in older houses. The stones become porous and allow water to pass through. Furthermore, the jointing can also be damaged, something like this can get worse after sandblasting your facade. Because it often rains in the UK, the walls are more often subject to damp. Plants such as ivy can also cause damage to the walls. Penetrating damp can often be recognized by irregular stains that look and feel damp, water spots on the ceiling and the top of the walls, damp walls on the 1st floor and higher and peeling paint and wallpaper. Solutions to this can be the replacement of the jointing or impermeating the wall.

Cold bridges
Because the insulation in the cavity is not properly installed thermal bridges can occur. Residual construction debris, mortar or cavity anchors can also provide a bridge between the inner and outer walls. This creates colder zones in those places and because moisture always attracts to the coldest place, it can start to condense. An inspection of the cavity would be a solution for this, to determine the problem and to tackle it correctly.

Living comfort
Whatever the cause of your damp problem in the home, it has a lot of adverse consequences. Health problems can occur because mould leaves tiny traces in the air. Breathing this in can cause all sorts of problems such as Allergies, respiratory tract infections, headaches, stuffy feeling and irritated skin. Due to a higher humidity, it also costs more energy to heat up the house, in combination with damp walls that lose their insulation values, there are a lot of extra costs every month.

Side note about moisture problems
All the solutions given above only work for one specific cause of the damp problem. However, damp often comes from multiple places. So when you apply one solution, it doesn't resolve all your issues. Fortunately, SmartDry has developed its newly patented elements that can permanently solve all these problems. Our system ensures a stable humidity in the house and makes the walls dry. We even dare to give a lifetime guarantee!
