A Guide to Preventing Mould in Rental Flats and Student Housing in Gweedore

Shared housing in Gweedore plays a big role in the local community—home to students, seasonal workers, and tenants who often come and go. But in high-turnover flats and student rentals, there’s one problem that tends to stick around: mould.

At Causeway Cleaning Ltd, we’ve been called to dozens of rental properties in Gweedore where mould had silently taken hold behind wardrobes, around window frames, and in poorly ventilated bathrooms—often without the landlord or letting agent even knowing it was there.

In this guide, we’ll break down why mould is such a common issue in rental properties, what landlords and tenants can do to prevent it, and how to maintain healthy air quality year-round.

Why Shared and Rental Properties Are High-Risk for Mould

1. Inconsistent Heating and Ventilation

In many student houses or shared flats, rooms are only intermittently heated—some tenants keep windows closed to save heat, while others dry clothes indoors. These habits trap moisture and create prime conditions for condensation-based mould.

Bathrooms and kitchens in particular suffer when:

• Fans aren’t used or maintained
• Windows are never opened
• Showers and cooking generate constant steam

Over time, the lack of airflow leads to black mould growth, especially in cold corners, ceilings, and near windows.

2. High Occupancy = High Moisture

The more people in one space, the more moisture is released into the air—through breathing, cooking, showering, or drying clothes. In Gweedore, where traditional homes may not be built for heavy use, this moisture builds up fast.

According to the HSE, mould exposure can cause coughing, wheezing, and sinus issues—and shared accommodation is especially vulnerable to hidden spores.

3. Lack of Ongoing Maintenance

High-turnover properties often go months or years without a deep inspection. Tenants may not report issues. Landlords might paint over visible mould but leave the underlying moisture problems untreated.

That means problems build quietly behind the scenes, ready to flare up during the next tenancy.

What We Typically Find in Gweedore Rentals

During our inspections, we’ve seen:

• Mould behind wardrobes and beds pushed against external walls
• Water damage under sinks from slow leaks
• Poorly sealed windows with black mould around frames
• Bathrooms with broken extractor fans
• Persistent musty odours in communal areas

Landlords: How to Prevent Mould in Student and Shared Housing

If you’re a landlord in Gweedore, you have a legal responsibility to provide safe, habitable accommodation. Here’s how you can take proactive steps:

✅ 1. Schedule Regular Inspections

Don’t rely on tenant reports alone—arrange a professional inspection every 12–18 months to check for hidden mould or moisture issues.

✅ 2. Upgrade or Maintain Ventilation Systems

Ensure extractor fans are installed in bathrooms and kitchens—and that they’re working. Replace noisy or broken fans immediately.

✅ 3. Use Mould-Resistant Paint

Particularly in bathrooms and around windows. It won’t stop mould caused by deeper issues, but it helps prevent surface growth in borderline areas.

✅ 4. Educate Tenants

Include a one-page guide on how to prevent mould when new tenants move in. It should cover ventilation, heating, and reporting leaks quickly.

✅ 5. Invest in a Mould Survey

We offer full moisture mapping, air testing, and DNA-level analysis for properties with recurring issues or odours.

Tenants and Students: How to Keep Your Room Mould-Free

Tenants also play a key role in mould prevention. Here’s what you can do:

✅ Use Extractor Fans or Open Windows

Always ventilate when cooking, showering, or drying clothes. If a fan isn’t working, report it right away.

✅ Keep Furniture Off External Walls

Leave a small gap to allow air flow and prevent condensation build-up behind wardrobes and beds.

✅ Don’t Block Vents

Covering trickle vents or closing off air bricks can lead to trapped humidity.

✅ Report Leaks and Damp Smells Early

A musty odour or brown mark on the ceiling might be more than just old paint—tell your landlord.

According to Threshold, tenants have the right to live in accommodation free from serious damp and mould—especially when it affects health.
