Ozone (O₃) is a molecule made of three oxygen atoms and is known for its powerful oxidizing properties. It's commonly used in industries like water treatment and food sanitation for its ability to neutralize bacteria, viruses, and mould spores.
In mould remediation, ozone is generated on-site using an ozone generator. When released into a sealed space, it oxidises organic compounds and neutralises airborne spores and odours.
For more technical details on ozone's properties and reactivity:

Ozone can reach concealed areas such as wall cavities and under floorboards, killing airborne spores and making post-remediation air safer.
It effectively breaks down the VOCs responsible for that distinctive "mouldy" smell.

How Ozone Eliminates Odors - Ozone Solutions
Traditional methods can't always penetrate behind plaster or inside voids. Ozone gas, however, seeps into these areas without requiring demolition.
Unlike some harsh biocides, ozone decomposes back into oxygen with no harmful residues.
Despite its strengths, ozone should never be the only method of mould remediation.
According to the IICRC S520-2024 standard:
"Ozone... should not be used as a substitute for source removal."

The EPA and American Lung Association warn that improper use can irritate lungs and worsen asthma:
Even the California Air Resources Board states that ozone can cause health issues above certain levels:
As Ireland's only IICRC-certified antimicrobial specialists, we take every precaution:
Ozone is not a standalone solution. Here’s how we integrate it:
A call came in from a property manager. Tenants had complained of persistent respiratory issues and a strong, musty odour. We discovered black mould behind built-in shelving due to a burst pipe months earlier.
After a full strip-out and sanitisation, we used ozone to treat the HVAC system and inaccessible voids. Post-job IAQ tests showed safe airborne spore levels. The odour was completely neutralised. The client signed off with full satisfaction.
Ozone gas can be an invaluable tool in the mould remediation process—if used safely and as part of a broader strategy. While it neutralises spores and odours effectively, it should never replace source removal or professional cleaning.
At Cleaning Contractors NI, we follow industry standards to deliver results that are safe, lasting, and fully verified. If you suspect mould in your home or business, book a mould survey with our expert team today.

Mould removal in Templepatrick isn’t always about cleaning visible spots. Sometimes, it’s about uncovering a hidden threat—one that silently affects your health, your comfort, and your family’s wellbeing.
This is exactly what happened in a local home, where a simple inspection led to a life-changing discovery. At Cleaning Contractors NI, we’ve seen first-hand how early detection can make all the difference.
Sarah and Mark had just moved into their dream home in Templepatrick. It was cosy, modern, and perfect for raising their two-year-old daughter. But within weeks, things started to change.
Their daughter developed a persistent cough. Sarah had constant headaches. Mark, who worked from home, felt drained all the time. With no obvious explanation, they began to suspect something was wrong inside the house itself.
That’s when they reached out for a mould inspection in Templepatrick.
When our team at Cleaning Contractors NI arrived, we carried out a full moisture survey using professional equipment. While the house looked clean on the surface, thermal imaging revealed damp patches behind the living room wall.
Behind the plasterboard? A large area of hidden black mould, caused by a slow leak in an old radiator pipe—just metres from the child’s play area.
Using certified IICRC methods, we acted fast:
This was a case where mould removal in Templepatrick wasn’t just about restoration—it was about protecting a family’s health.
Mould doesn’t always show up as black spots on the wall. It hides. It grows silently. And it releases spores into your air, affecting your lungs and immune system. In children, the elderly, or anyone with respiratory issues, the impact can be significant.
If you live in Templepatrick and you’ve noticed any of the following:
One small inspection gave this family their health back—and peace of mind. Could it do the same for you?
If you're concerned about hidden mould, don’t wait. Let Cleaning Contractors NI carry out a safe, certified mould removal inspection in Templepatrick.

You expect to see mould in bathrooms. Maybe around windows. Possibly the odd damp patch behind a wardrobe. But over the years, our team at Cleaning Contractors NI has uncovered mould in places that genuinely surprised even the homeowners.
Carrickfergus might be known for its castle and coastline—but beneath the surface of many homes, a hidden battle with mould is taking place.
Here are five unexpected places we’ve found mould while carrying out mould removal in Carrickfergus—and why it matters.
Yes, really.
We were once called to a home in Carrickfergus where the occupant kept waking up with headaches and sinus issues. The culprit? Mould inside the mattress and the fabric headboard. A combination of poor ventilation, high humidity, and sleeping in the same spot night after night had turned a bed into a breeding ground.
💡 Pro Tip: If your bedroom feels stuffy or you dry laundry indoors, check under and around your bed regularly.
Mould loves areas with poor air circulation—and when frames are tightly hung against exterior walls, they can trap moisture behind them. We’ve found full colonies of mould hiding behind artwork, totally unnoticed until we removed it during a routine inspection.
💡 Pro Tip: Leave a small gap between frames and walls, especially in older or poorly insulated properties.
Cupboards next to sinks or on exterior walls are prone to condensation and steam build-up, especially when not opened frequently. We’ve discovered mould spreading quietly along the backs of kitchen units, contaminating plates, food packaging, and cutlery drawers.
💡 Pro Tip: Open your cabinets regularly, especially under the sink, and install ventilation grilles if needed.
One Carrickfergus family noticed a “damp smell” but couldn’t find the source. When we lifted the laminate floor in their hallway, we found black mould growing on the subfloor. A slow pipe leak under the boards had been feeding it for months.
💡 Pro Tip: If a room smells musty or flooring feels slightly uneven or warped, it’s time for a proper survey.
This one hits hard—especially for parents. We’ve found mould growing inside plastic toys, fabric dolls, and even inside sealed toy boxes in damp bedrooms. Often caused by damp hands or toys stored while still wet, these hidden patches can pose a health risk to little ones.
💡 Pro Tip: Dry toys thoroughly before storing, and regularly wipe out toy boxes with a disinfectant.
Just because you can’t see mould, doesn’t mean it isn’t affecting your health. Hidden mould spores can circulate through the air, triggering asthma, allergies, and even fatigue or brain fog. If you’re feeling unwell at home but can’t pinpoint why, mould might be the missing piece of the puzzle.
That’s why our professional mould removal service in Carrickfergus goes beyond surface-level fixes—we inspect, test, treat, and advise so it doesn’t come back.
We’ve been helping families in Carrickfergus safely remove mould for years—and the stories we could tell would surprise you.
If you're ready for peace of mind, book a certified mould inspection in Carrickfergus today.

You spot a bit of mould on the wall. No big deal, right? Maybe you’ll grab some vinegar, baking soda, or bleach. A quick wipe and it’s gone. Problem solved?
Not quite.
Across Lurgan, many homeowners are taking the DIY route when mould appears—and later finding themselves stuck in a frustrating cycle. It’s tempting to rely on household remedies, but the truth is, mould removal in Lurgan isn’t always that simple.
So, do natural methods actually work? Or is professional help the better option? Let’s break it down.
There’s no denying the appeal of natural solutions. They’re affordable, easy to find, and often feel safer than harsh chemicals. In Lurgan homes, some of the most common mould remedies include:
In certain cases, these can work—on smooth, non-porous surfaces like tiles or glass. They may remove surface mould temporarily, especially in low-moisture environments.
However, these fixes are often short-term.
DIY solutions often fail to address the root cause. Surface cleaning might make the wall look better, but the mould could be growing deeper inside. Plus, without proper containment, scrubbing can release spores into the air, spreading the problem to other rooms.
Additionally, most DIY efforts don’t include checks for underlying issues—like hidden leaks or poor ventilation. These are the real culprits behind recurring mould in homes across Lurgan.
This is where experts like Cleaning Contractors NI come in. With professional mould remediation, the process goes far beyond what’s visible to the eye.
We begin with a full moisture assessment and detailed inspection to uncover hidden problems. Then we apply IICRC-certified antimicrobial treatments that not only remove mould but also kill spores and stop regrowth. Finally, we give honest advice on how to prevent it from returning—because long-term protection matters.
In fact, we’re proud to be the only IICRC-certified antimicrobial cleaning company in Ireland. That means we follow global best practices and deliver professional results every time.
So what’s the verdict?
If you’re dealing with a tiny patch on a tiled surface, you might get away with a vinegar wipe-down. But if you notice:
Stop wasting time on short-term fixes. If you're serious about tackling mould in your Lurgan home, Cleaning Contractors NI is here to help.

Mould removal in Coleraine isn’t just a health concern—it could be the key to improving your focus and productivity if you work from home. As more people across Northern Ireland set up long-term home offices, one hidden threat is affecting their performance: mould.
Many homeowners in Coleraine don’t realise how much indoor air quality impacts brain function, energy levels, and even mental health. If you’re struggling with fatigue, headaches, or poor concentration, it might not be burnout—it could be mould.
At Cleaning Contractors NI, we provide expert mould removal in Coleraine to help you breathe easier and work smarter.
When mould spores are present in your home office, they release irritants and, in some cases, mycotoxins. These substances can directly affect your respiratory system and cognitive function. In turn, you may notice:
These effects are even more pronounced in small, poorly ventilated spaces—which is often the case for home offices.
Coleraine’s climate—frequent rain, cool temperatures, and high humidity—creates the perfect environment for mould. Many homes have older insulation, blocked vents, or condensation build-up on cold surfaces like windows and walls.
Additionally, people often seal their homes tighter during winter to stay warm. While this saves energy, it also traps moisture and allows mould to thrive.
Creating a mould-free workspace can do wonders for your daily performance. Here’s how you can start:
We’re proud to be the only IICRC-certified antimicrobial cleaning team in Ireland, providing trusted mould removal services in Coleraine and across Northern Ireland.
Here’s what makes us different:
We don’t just remove the visible mould—we identify the root cause and give you advice to prevent it returning.
If you work from home and suspect that mould is affecting your productivity, it’s time to take action. Cleaning Contractors NI can help you reclaim your space—and your focus.

If you’re searching for mould removal Hillsborough, you’ve likely noticed black mould patches, musty odours, or condensation on your windows. These are common signs that mould is taking hold—and winter in Hillsborough only makes things worse. As temperatures drop, excess moisture gets trapped indoors, and poorly ventilated rooms become breeding grounds for mould growth.
At Cleaning Contractors NI, we offer certified and discreet mould removal in Hillsborough and surrounding areas. Whether your problem stems from condensation, poor insulation, or hidden leaks, our IICRC-accredited team is here to help restore your property and peace of mind.
As outside temperatures fall, indoor heating systems get cranked up. But what many homeowners don’t realise is that this warm air collides with cold surfaces—leading to condensation.
These moisture issues are especially common in older Hillsborough homes. Without proper airflow and temperature balance, condensation mould forms quickly—often appearing in bedrooms, bathrooms, or behind furniture.
For more guidance on understanding condensation, see NI Direct’s guide to condensation and damp.
Some signs of mould may seem minor at first, but they can escalate quickly—especially in the colder months. Here’s what to look out for:
If you notice any of these issues, it’s time to schedule a mould survey in Hillsborough to assess the scale of the problem before damage or health issues worsen.
Explore our Mould Survey Service for more details.

4. Prevention Guidance
Our report includes tailored advice on insulation, extractor fans, ventilation upgrades, and dehumidifiers to stop the problem returning.

While we can professionally remove all visible signs of mould, it’s equally important to manage indoor moisture moving forward.

Hard Floor Cleaning Hillsborough
A Real Case Study from Cleaning Contractors NI
When we say mould can take over a home, we’re not exaggerating. In one of our most challenging jobs to date, our team at Cleaning Contractors NI was called out to a family property in Craigavon—and what we found was more than surface-level staining. It was a full-blown mould Craigavon infestation affecting the structure, air quality, and the family’s wellbeing.
But this story has a happy ending. Here’s how we turned the situation around.
The homeowners first called us after their youngest child developed a persistent cough. Doctors suspected environmental triggers, and that’s when they started looking closely at their home. Behind wardrobes, beneath carpets, and around windows—black mould was spreading fast.
When we arrived, the smell was immediate. Strong, musty, and unmistakable. Moisture readings revealed elevated humidity in several rooms, and thermal imaging highlighted cold bridging and condensation issues.
Most concerning of all? Hidden mould growth in a child’s bedroom wall cavity, undetectable without professional tools.
Mould was not only present—it was thriving. Conditions in the property created the perfect storm:
It wasn’t just a cosmetic issue anymore. It was a health hazard.
Our certified mould remediation specialists wasted no time. Here’s how we tackled it:
Throughout the process, we worked around the family’s schedule, keeping their safety and comfort a top priority.
Within days, the air quality improved. The child’s symptoms eased, and for the first time in months, the family could breathe easy—literally and emotionally. The home smelled fresh, looked brighter, and was finally safe again.
A follow-up mould inspection in Craigavon three months later showed no signs of regrowth.
If you’re living in Craigavon or anywhere in Northern Ireland and dealing with recurring damp, musty smells, or unexplained health symptoms—don’t wait. Hidden mould spreads fast, but with the right team, it can be stopped.

Cleaning Contractors NI Explains the Key Differences – And Why It Matters for Your Home
You spot a strange patch on your wall or bathroom ceiling—white, green, maybe even black. Is it mildew? Is it mould? And more importantly… does it matter?
If you live in Cookstown and you're dealing with suspicious stains or musty smells, knowing the difference can help you act faster, protect your health, and prevent damage to your property. At Cleaning Contractors NI, we’re here to break it down in plain language.
Mildew is a surface-level fungus that tends to appear in damp, warm areas like bathrooms, windowsills, and laundry rooms. It’s often white or light grey and can be wiped off fairly easily if caught early.
Common signs of mildew:
While mildew might seem harmless, it can still trigger allergies and worsen asthma if it’s allowed to linger.
Mould, on the other hand, is more invasive and potentially more dangerous. It penetrates surfaces and feeds on organic materials like plaster, wood, wallpaper, and insulation. Mould comes in a variety of colours—black, green, blue, even orange—and it’s not just unsightly. It can cause serious health issues and property damage.
Key traits of mould:
Black mould, in particular, is a common problem in Cookstown homes with poor ventilation or rising damp.
Homes in Cookstown and across Mid Ulster face higher risks due to frequent rain, cooler temperatures, and traditional building styles that may not prioritise airflow. We’ve helped property owners all over the area—especially in older terraced homes and rentals—deal with both mildew and serious mould infestations.
Whether you live near Fairhill, Molesworth, or just outside the town in a rural home, mould and mildew can sneak in faster than you might expect.
Here’s a quick comparison guide:
| Feature | Mildew | Mould |
|---|---|---|
| Texture | Powdery, fluffy | Fuzzy or slimy |
| Colour | White, grey, yellow | Black, green, brown, orange |
| Smell | Slightly musty | Strong, pungent, earthy |
| Depth | Surface only | Deep-rooted, can damage structure |
| Risk | Mild irritation | Respiratory issues, long-term health effects |
If you're unsure what you’re dealing with, don’t guess—especially if anyone in your home has allergies or asthma. It’s always better to have a professional mould survey in Cookstown carried out.
At Cleaning Contractors NI, we offer:
We’re also the only IICRC-certified antimicrobial remediation specialists on the island of Ireland—so you know you’re in good hands.

Discover the Hidden Problem Affecting Health in Northern Ireland Homes
Have you been waking up feeling tired, foggy, or simply not yourself? Before you assume it's just stress or poor sleep, it's worth asking: Could mould in your Limavady home be the cause?
At Cleaning Contractors NI, we’ve seen firsthand how hidden mould can quietly impact the health and wellbeing of families across Limavady. From chronic fatigue to constant sniffles, the effects are more common than you’d think—and easier to miss than you’d hope.
Mould isn’t always visible. In fact, it often hides behind furniture, under flooring, or inside poorly ventilated walls. Yet, even when you can't see it, mould spores can circulate in the air, leading to a wide range of health issues.
You might experience:
As time goes on, these symptoms can worsen—especially for children, the elderly, or anyone with existing respiratory conditions. However, many people report feeling better once they spend time away from home, which can be a key sign that mould is the culprit.
Thanks to our damp Northern Irish climate, Limavady properties—especially older homes or rentals—are often ideal environments for mould growth. Cold walls, poor insulation, and blocked ventilation can allow moisture to settle and mould to flourish.
Furthermore, modern airtight construction can unintentionally trap humidity indoors. Without proper airflow or extraction, mould has everything it needs to thrive.
Whether you're living in a semi-detached home in the Roe Mill area or a countryside bungalow near Ballyquin, you’re not immune.
We’re not your average cleaning company. Cleaning Contractors NI is the only IICRC-certified antimicrobial remediation company on the island of Ireland. We specialise in finding the hidden sources of mould and removing them safely and thoroughly.
Here’s what we offer for homes in Limavady:

We recently helped a family near Catherine Street. The parents had been feeling exhausted for months, and their daughter developed a persistent cough. When we carried out a mould survey, we discovered a significant mould infestation behind a wardrobe on an external wall. After professional removal and simple ventilation changes, their symptoms dramatically improved.
Mould doesn’t just damage buildings—it affects lives. If you’ve been feeling unwell without explanation, now is the time to act. A mould survey could be the first step to restoring both your home and your health.
