Have you discovered black spots creeping across your ceiling, a musty smell in the air, or patches of discolouration near windows and wardrobes? If you’re a homeowner in Newtownabbey, you’re not alone. Mould is a growing problem in both older homes and newer, tightly sealed properties throughout the town—and it’s often caused by something as simple as trapped moisture.
At Cleaning Contractors NI, we specialise in expert mould removal in Newtownabbey and across Northern Ireland. As the only IICRC-accredited antimicrobial remediation team on the island of Ireland, we offer a level of service, safety, and knowledge that sets us apart. Here’s what you need to know if mould is affecting your home—and what can be done to stop it from returning.
Mould thrives in environments where warmth, moisture, and poor ventilation combine. Many homes in Newtownabbey—especially those with older construction or insufficient insulation—experience regular condensation. This isn’t just a nuisance; it’s the primary cause of black mould growth on ceilings, around windows, and even behind furniture.
While it’s easy to mistake condensation-related mould for a leak or rising damp, the root cause is usually moisture in the air that has nowhere to escape.
Over the past 16 years, we’ve surveyed and treated hundreds of mould-affected homes across areas like Glengormley, Jordanstown, Whiteabbey, and Ballyhenry. The most common locations we find active mould growth include:
If you notice mould appearing in more than one room, or it returns shortly after cleaning, it’s a sign that the underlying problem hasn’t been fixed—and that’s where professional help is essential.
Mould isn’t just unsightly—it’s a proven health hazard, particularly for vulnerable groups like children, the elderly, and anyone with respiratory conditions. According to the NHS guide to damp and mould, prolonged exposure to mould spores can cause:
If your property is affected by mould, removal must be done properly—not just wiped off with bleach or vinegar. DIY cleaning can agitate spores and actually make indoor air quality worse.
As a Senior Member of the National Carpet Cleaners Association (NCCA) and a WoolSafe Approved Inspector, we’ve built a strong reputation for excellence. But when it comes to mould, our work goes far beyond surface cleaning.
Our IICRC-approved mould remediation process includes:
We begin with a thorough moisture survey using thermal imaging, digital hygrometers, and airflow meters to identify the source of moisture—not just the symptoms.
Our team wears appropriate PPE and uses negative air machines to prevent cross-contamination. We remove mould using certified antimicrobial products that are safe for families and pets.
For more complex or recurring problems, we offer mould DNA testing to identify hidden contamination and airborne spore levels. This service is especially useful for pre-sale property inspections or legal disputes involving landlords and tenants.
Once the mould is gone, we help you keep it away. This includes guidance on extractor fan use, humidity control, insulation upgrades, and ventilation improvements.

The biggest mistake homeowners make is waiting too long. Mould doesn’t stay still—it spreads. It can rot woodwork, damage plaster, and even affect your property value. Worse still, visible mould usually means invisible spores are circulating through your air.
If you’re a landlord in Newtownabbey, you also have a legal duty to provide a safe and habitable property. The Housing Executive and environmental health departments regularly inspect mould-affected homes, and ignoring reports from tenants could result in fines or legal claims.
Don’t wait until the mould spreads or your family’s health declines. Contact the experts who understand the science of mould—and how to stop it for good.
