If you live in Donegal Town, you’re no stranger to grey skies and long stretches of damp, rainy weather. But what many homeowners don’t realise is how much Donegal’s climate—combined with poor indoor ventilation—is quietly fuelling mould growth, especially in bathrooms and kitchens.
At Causeway Cleaning Ltd, we’re seeing more and more cases where mould problems aren't caused by flooding or leaks, but simply by trapped moisture in poorly ventilated spaces. Bathrooms, wet rooms, utility areas, and kitchens are especially at risk.
So let’s take a closer look at what’s happening, and more importantly—what you can do about it.
Bathrooms and kitchens generate a lot of moisture. Showers, baths, kettles, boiling pots, dishwashers—all of these release steam into the air. Without proper ventilation, this moisture lingers, settles on cold surfaces, and eventually leads to mould.
And it’s not just unsightly—black mould (Stachybotrys chartarum) and other fungi release spores that can lead to respiratory problems, sinus irritation, and skin issues.
According to the HSE, mould exposure in the home can cause symptoms such as coughing, wheezing, headaches and fatigue—especially for children, older adults, or those with asthma.
Donegal Town receives over 1,200mm of rainfall annually, with humidity levels often hovering above 80%—even indoors.
These conditions mean that water vapour from cooking or showering takes much longer to dissipate unless mechanical ventilation is in place.
Met Éireann confirms that persistent high humidity in the northwest contributes to damp homes—especially where heating is inconsistent.
Not sure if your kitchen or bathroom is ventilating properly? Look out for these red flags:
If you’re noticing any of these, you could be dealing with an underlying mould issue caused by poor airflow—and it won’t get better on its own.

The good news is that ventilation-related mould is preventable—and in most cases, without major structural work.
A fan should run during showers or cooking and ideally for 15–20 minutes afterward. If it’s noisy, dusty, or ineffective, replace it.
Even a small gap can significantly reduce condensation after cooking or bathing.
This helps protect vulnerable surfaces like ceilings and corners from moisture absorption.
Especially in bathrooms—this adds litres of moisture to the air.
Inexpensive digital hygrometers can help you track humidity and take action before mould grows.
The NHS recommends keeping indoor humidity between 40–60% to prevent mould and reduce respiratory symptoms.
If mould has already appeared—even if it’s small—it’s important to act fast. Surface sprays and bleach only mask the problem. Spores can remain in porous surfaces like grout, plaster, and even behind paint.
