Condensation. We all know it: fogged-up windows on a cold winter’s day, droplets running down the bathroom tiles, or that clammy feeling in the basement .
On its own it seems harmless, but when condensation is a persistent presence in your home, it can become a serious problem. Think mould spots, musty odours, damaged walls and even health issues. It’s best to tackle that condensation. So how do you do that?
So What Exactly is Condensation?
Condensation occurs when warm, humid air comes into contact with a colder surface. The moisture in the air then condenses back into liquid. The result: tiny droplets on windows, walls, ceilings or mirrors.
A bit of condensation is perfectly normal, especially right after a hot shower or a long cooking session. At those times there’s a lot of water vapour in the air, so condensation is likely to form. But if it becomes persistent, the walls become increasingly saturated with moisture and it lingers. That’s when the trouble starts.
The 2 Main Causes of Condensation
In theory, condensation can be caused by several factors, but two really stand out: poor ventilation and thermal bridges.
1. Lack of ventilation
This is without a doubt the most common culprit. A home where the air cannot circulate sufficiently traps moisture. Fogged-up windows or mirrors are often the first signs of a serious moisture problem. Especially in wet rooms such as the bathroom, kitchen or laundry room, a lot of moisture is produced. If you don’t have a ventilation system at home or can’t open a window, you need to be extra careful there.
2. Thermal bridges
The second major cause is thermal bridges. These are weak spots in the structure where the insulation is insufficient and cold air can enter. In those places the wall cools down much faster. Those are the spots where condensation will form very quickly.
The culprit is often a poorly insulated cavity wall or a concrete beam that runs straight through to the outside. Condensation can also form more quickly around poorly sealed windows and doors, or where the roof sits on the walls.
Condensation in the Basement
Not every room in your home is equally susceptible to this type of moisture problem. Condensation mainly rears its head in places where a lot of moisture is produced, or where temperature differences are significant. We’ve already mentioned bathrooms, kitchens and laundry rooms. Those are real hotspots. You also need to watch out in poorly insulated areas where thermal bridges have formed.
But one space that deserves extra attention is the basement. Because it’s naturally cooler and ventilation often lacks, it’s the ideal place for condensation to form. In a basement that’s almost unavoidable. It’s easy to get stuck in a vicious circle: moisture condenses, then evaporates again as temperatures change, and then simply settles again. The humid air has nowhere to go.
The Effects of Condensation
A bit of steam after a shower is no big deal, but persistent condensation can seriously damage your home. Some of the effects:
- Mould growth on walls, ceilings and furniture.
- Health issues such as respiratory problems, allergies, or irritated airways.
- Damaged materials, such as wallpaper coming loose, peeling paint, and wood starting to rot.
- Poor air quality, with a musty, clammy smell that’s hard to get rid of.
- Higher energy costs, because damp walls not only cause moisture problems but also let heat escape.
What Can You Do about Condensation in your Home?
Fortunately, there are solutions. Depending on the cause, a few measures can already make a big difference.
Better ventilation
A proper ventilation system is the key. For a structural solution, mechanical ventilation is the better choice. An exhaust system is practically essential, especially in wet areas.
Insulation and tackling thermal bridges
Do you notice condensation returning in the same spot? Then there’s likely a thermal bridge. The solution often lies in additional insulation.
Additional tips for daily life
- Always turn on the range hood while cooking.
- Leave the bathroom door and window open after showering and use a fan.
- Preferably dry laundry outside or use a dryer.
- Always ventilate the bedroom right after getting up, even when it’s cold outside.
When should You Call an Expert?
Not sure where the moisture is coming from? Then it’s wise to consult a moisture expert. They can quickly and accurately identify the cause. This prevents you from wasting time and money on partial solutions that don’t really address the problem.
You might not be dealing with a condensation problem at all, but rather with rising damp or penetrating damp. In that case, you’ll need moisture control of a completely different caliber.
