Mould Remediation Drogheda | How We Solved a Dangerous Black Mould Case

Mould in Apartments: What We Discovered in Drogheda and How We Fixed It

We recently got a call from a property manager in Drogheda who was growing increasingly worried about complaints from tenants in a large apartment complex. It started with one unit — a black patch above the bathroom window. Then another tenant reported a persistent musty smell. A third had mould growing behind a wardrobe.

By the time we arrived, five different apartments had some form of visible or hidden mould. And the biggest surprise? None of these buildings were particularly old. But they did have one thing in common — poor ventilation and high-density living.

Here’s how we diagnosed the issue, treated it, and gave residents a safer space to breathe again — and what other landlords and tenants in Drogheda, Tullyallen, Mornington, or Donore should watch out for too.

A Problem Growing Beneath the Surface

The building was typical of modern flats in Drogheda — energy-efficient on paper, but tightly sealed, with very little airflow. As a result, steam from showers, cooking, and even drying clothes indoors had nowhere to go.

In one case, a tenant had no extractor fan in the bathroom and was using an oil-filled radiator for heat. The moisture levels were off the charts. Behind their wardrobe, black mould was creeping up the wall, hidden until the smell got too strong to ignore.

We used DNA swab testing to confirm Stachybotrys chartarum, commonly known as toxic black mould — the kind linked to serious respiratory problems in children and the elderly. According to the HSE, exposure to mould spores can worsen asthma, irritate lungs, and even cause fatigue or skin problems.

Why Flats and Apartments Are So Vulnerable

It’s not just about how buildings are built — it’s about how we live in them. Apartment living naturally leads to:

High indoor humidity from daily activities
Shared ventilation systems that don’t always do the job
Limited airflow from sealed windows and no chimneys
Furniture pushed against walls, restricting air circulation

Add in our famously wet Irish climate, and it’s no wonder we’re seeing a spike in calls for mould remediation in Drogheda — particularly in apartment blocks.

Step One: Surveying the Scene

Our team carried out a full mould survey across all affected flats. Using digital moisture meters, infrared cameras, and lab-backed swab tests, we identified problem areas — many of which weren’t visible to the naked eye.

One unit in particular had airborne spore counts 10x higher than healthy limits.

Step Two: Remediation That Actually Works

Over the course of three days, we:

Removed visible mould using anti-microbial treatments
Applied air-purifying fog treatments to reduce airborne spores
Deep-cleaned extractor fans, vents, and window frames
Advised dehumidifier placement and air exchange improvements

We also educated tenants on ventilation, drying laundry properly, and how to spot early warning signs.

The Result: Better Air, Better Health

After our work was done, we returned two weeks later for follow-up testing. Spore levels had dropped dramatically. Residents reported improved sleep, fewer headaches, and no more musty odours.

We also provided a full written report for the landlord — not just for documentation, but to help prevent the issue from returning.

Mould Prevention Tips for Apartment Residents

Even if you’re renting, there are things you can do to reduce your risk:

Open windows for 10–15 minutes daily to flush out stale air
Leave internal doors open to balance humidity
Dry clothes outdoors when possible, or near a window with airflow
Use lids when cooking and extractor fans if available
Don’t block external walls with furniture — give them space to breathe

And if you’re a landlord, make sure bathrooms have proper fans and offer tenants a guide on managing indoor air quality.
