Reasons you might need professional mould removal

While small patches of mould can sometimes be treated yourself, more serious or recurring problems often require professional help to make sure they’re fully removed and don’t return.

You'll need a mould removal specialist if:

• The mould covers a large area (typically more than 1m²)

• It keeps coming back after cleaning

• There’s a strong, persistent musty smell

• It’s affecting multiple rooms or hidden areas (e.g. behind walls or ceilings)

• You suffer from allergies, asthma, or other health concerns

• You’re preparing a property for sale or rental and need a long-term solution

A professional will not only remove the mould safely, but also identify the root cause and offer guidance on how to prevent it from returning.

Factors affecting mould removal costs 

Here's some of the most common factors affecting the overall cost for mould removal:

• Type of mould: Some types may be easier to remove than others

• Amount of mould: The more mould to be removed, the higher the labour costs will be

• Time taken: The longer the job takes, the greater the labour costs will be

• Ease of access: When mould takes root in hard-to-access areas, this can increase the price of removal

• Location: Certain areas, such as London, have a higher price for mould removal

Cost of hiring mould removal services vs DIY

You might be wondering whether you can save on the cost of hiring an expert by tackling mould removal yourself.

When considering whether you are able to remove mould, you should take into account:

• Type of mould (some are more difficult to remove)

• The extent of the mould contamination

• Your physical ability (mould removal requires elbow grease and involves climbing ladders to reach difficult areas)

• Potential danger (never breathe in or touch mould with your bare skin)

• Related costs (you'll need to invest in protective gear and specialist solutions to prevent the mould from returning)

Hiring a professional means you can be certain that all the mould is removed. They can also help you understand the cause of the mould to prevent its return.

FAQs

Why remove mould?

Not only does mould look unsightly, but it can also:

• Damage anything it comes into contact with, from walls to ceilings as well as soft furnishings

• Create nasty odours

• Become a health hazard, especially to vulnerable people and children, if left untreated

What causes mould and mildew?

Mould and mildew are caused by excess moisture. When moisture builds up on walls or ceilings, it creates the ideal environment for mould to grow. Common sources include:

• Condensation from showers, cooking, and drying clothes

• Poor ventilation

• Inadequate insulation

• Leaks from pipes

• Rain entering through structural cracks

What are common types of mould?

The types of mould you’re most likely to encounter are:

• Black mould (or Stachybotrys Chartarum): The most common type of mould, and easiest to remove

• Green mould (or Penicillium): This mould can appear fluffy and deteriorate paint, as well as cause other damage

• Blue mould: Most prevalent in wet rooms like bathrooms, and can often be seen on walls and ceilings

• White mould: This white mould likes cool and damp environments, such as basements

What happens if you don’t remove mould?

Ignore mould, and it will spread quickly, release harmful spores, damage your home, and cause unpleasant odours. It can also lead to health issues like allergies and breathing problems, especially for vulnerable people.

How much does a mould removal specialist cost?

The average black mould removal cost is £300 per job. However, the total cost depends on the size and severity of the problem.

How much should I pay for mould removal services? 

The average mould removal cost per hour is £30. However, exactly how much you should pay for mould removal services, and how long it takes, will depend on factors like the extent of the problem and the type of mould.

How much does mould removal cost for an entire house?

The average cost of mould removal services for an entire house is £1,200. With an area this large, the time required to eradicate mould is relatively high, leading to an expensive job. This is why it’s better to tackle any small mould growths before they spread.

What mask is best for mould removal?

For mould removal, a high-filtration respirator such as an FFP3 mask is recommended. Professionals use FFP3 or P3-rated masks along with gloves and eye protection to avoid inhaling harmful spores.

What is the best cleaner for mould removal?

Specialist anti-mould or fungicidal cleaners are the most effective, as they kill spores and help prevent regrowth. Professionals may also use antimicrobial treatments for longer-lasting results.

Is sugar soap good for mould removal?

No, sugar soap is not designed to kill mould. It may clean surface dirt, but won’t eliminate spores or stop mould from coming back, so a proper mould treatment is recommended.

How long does professional mould removal take?

Small jobs can take two to four hours, while more extensive mould removal across a property may take a couple of days, depending on severity.

Does house insurance cover mould removal?

Whether or not house insurance covers mould removal depends on the cause. Insurance may cover mould removal if it results from a sudden issue like a burst pipe. But it usually won’t cover mould caused by long-term damp or poor ventilation.

Is mould remediation the same as removal?

No, mould removal refers to cleaning visible mould. Meanwhile, mould remediation is a more comprehensive process that removes contamination and addresses the underlying cause to prevent it from returning.

Is professional mould removal worth it?

Yes, getting in a mould removal professional is key to stopping mould in it's tracks. Left untreated, mould can:

• Damage walls, ceilings and furnishings

• Cause unpleasant odours

• Pose health risks
