How Much Does Mould Removal Cost?

The average cost of removing mould from a single, large room is £220 to £280. However, to have the mould removed from an entire property would likely set you back between £725 and £1100.

The cost of removing mould depends on the nature of the damaged area, type of mould, room type, number of rooms, ease of access, and your property's location. The reason that your location matters is because labour prices vary throughout the UK.

Labour costs are generally the highest in the southeast, with London known for having some of the country's highest tradesperson costs.

In contrast, labour prices tend to be below the UK average in regions such as the north of England and Scotland. This is due largely to varying living costs across the nation.

Additional Costs

What else might I pay for?

There are plenty of extra jobs you may wish to pay for with mould removal. Let's take a look at some potential added costs.

Painting a Room

Once mould has been removed from a room or several rooms for that matter, you may decide that you'd like to have the room(s) repainted.

Painting a wall

To have one room painted with two coats of emulsion costs about £350 to £450. For the same job with the removal of old wallpaper, you'd need a budget of around £450 to £550.

Hanging Wallpaper

If you'd rather hang fresh wallpaper, this would cost about £250 to £350 if performed by a professional. The cost of stripping old wallpaper, preparing the wall, and hanging wallpaper will cost approximately £500 to £600.

To replace the wallpaper in a large double bedroom with a bay window would set you back roughly between £700 and £760.

Labour Costs and Timescales

We'll now discuss the price of labour to remove mould. To remove mould from a large room is likely to come with a labour cost of £200 to £250. As for removing mould from an entire house, this is likely to have a labour cost of about £700 to £1000.

Preparation is likely to take under an hour, while the mould removal would take somewhere between an hour and eight hours to remove mould from a large room or one to five days for an entire house.

Both the labour prices and timescales depend on ease of access, the state of the work area, and the extent of the mould. Labour costs can also be shaped by your location.

Cost Factors of Removing Mould

There are many factors that determine the cost of having mould removed. Let's take a closer look at some of the clearest examples, such as mould type and ease of access.

Mould Type

There are varying costs for removing different types of mould as some are more difficult to remove than others. The more challenging it is to fix the issue, the longer it will take and therefore, the higher the labour prices are likely to be.

Type of Mould Removal Job

There are certainly a wide range of mould removal jobs that you may wish to pay for, including the removal of mould from a small room, medium room, large room, or even an entire house.

The larger the size of the removal area, the more you will pay in labour costs and also likely in supply costs.

Ease of Access

The more accessible a work area is, the easier the work will be, and in turn, the cheaper the job is likely to be. This is due to the fact that labour prices are tied to the timeframes of the work.

What's involved in Mould Removal?

Let's now discuss the steps involved in removing mould. The methods necessary can vary depending on the type of mould being removed, among other factors.

1. Hiring a Contractor

The very first step to consider is the hiring of a professional for the mould removal work. That is unless you'd prefer to undertake the job as a DIY project.

When employing a contractor to remove mould, you should seek quotes from three separate professionals or/and mould removal services, as well as references from each option.

This way, you'll increase your odds of finding someone who is above-average in their trade and hopefully, you'll get a good deal in the process.

2. Removing the Cause of Moisture

Condensation, poor ventilation and damp-related issues can all lead to mouldy walls, ceilings, and so forth.

Before the actual mould can be removed, it's important the source(s) of moisture are located and dealt with.

Otherwise, any efforts to remove the mould will be a mere short-term solution.

3. Removing the Mould

With the adequate safety equipment used, a professional will likely open the windows before using a cleaning solution to wipe away the mould.

A small rag and a solution of three parts water and one part chlorine bleach are likely to be used.

The mould should be gathered on the rag rather than brushed off the surface as this can spread the mould.

As soon as the wall or ceiling appears clear of the mould, a dry towel or rag can be used to dry the surface.

4. Clean Up

Beyond that, a professional will likely use wet wipes of vacuuming to remove mould spores from other room surfaces to ensure that the issue is unlikely to re-emerge at a later date.

Assuming the source of moisture has been adequately resolved, and then the problem will hopefully not return.

Can I Remove Mould Myself?

What if I want to remove mould myself?

It is suitable to remove mould on a small scale. For instance, it's reasonable to undertake small green mould removal or black mould removal DIY.

However, for a larger area, it is best to hire a professional. A professional does not need to sign off on this work. There is a range of risks to consider, with that being said.

Here's another thing…

On the one hand, if you fail to remove the mould successfully, or accidentally spread it around, or fail to remove the source of moisture, then you may not actually solve the issue in the long run.

In addition, inhaling mould can be dangerous, so it is important that you wear the right safety equipment (i.e. gloves, goggles, and mask).

Building Regulations & Planning Permission for Mould Removal

In general, there are no specific building regulations related to removing mould, nor does planning permission apply.

However, if you wish to undertake additional work, then these considerations may be important.

More information on building regulations and planning permission is available on the Planning Portal.

However, please note that the rules listed on Planning Portal are specific to England and Wales, and therefore you may find different rules for Northern Ireland and Scotland.

But that's not all.

Applying for building regulations costs around £300 to £400, while submitting a planning permission application costs between £200 and £400. You usually need to wait up to eight weeks for a response in relation to planning permission approval.

Types of Mould

There are many types of mould that can cause problems in a home. In this section, we'll take a closer look at some of the most common examples.

Green Mould

The first type is a particularly common example. It may suggest the presence of penicillium, aspergillus, or cladosporium.

Beyond its aesthetic issues, these spores can be harmful to health and may also lead to structural damage.

Green mould

Green mould may be somewhat fluffy and tend to be found on damp surfaces. The process discussed earlier can apply in most cases of green mould, and the same applies for white and blue mould and often for black mould too.

White Mould

Similarly to the green mould, this type has a fluffy appearance. It is likely to be found on damp timber.

White mould

It may appear in damp, cool environments (e.g. a cellar or basement). White mould often grows up walls and should not be mistaken for efflorescence.

The latter results from salt deposits and may appear on the surface of brickwork or concrete.

Black Mould

Another fairly common type of mould is black mould. It tends to come from the same strain as green mould but can be particularly harmful.

Black mould can produce conidia in the heads of slime and may be found in grain and soil.

However, it most commonly appears in building materials that are rich in cellulose and this results from buildings that have been damaged by water.

Black mould

Toxic black mould, also known as stachybotrys, can cause serious health issues.

The process of removing black mould if it is toxic can differ from that of other moulds.

For instance, a stronger product may be needed, and a professional should be hired to deal with toxic mould.

Blue Mould

Lastly, there is also a risk of homes suffering with blue mould. The wettest rooms of a house are more prone to blue mould (e.g. a bathroom).

Blue mould

This type of mould often appears on walls and rises up toward the ceiling. Steam is particularly troublesome in supporting the growth of blue mould.

Hiring a Mould Removal Specialist Checklist

When looking into professional mould removal, there are a range of points to take into account. Let's have a look at these considerations.


  • What are the qualifications of the tradesperson? (please note that qualifications are not generally necessary)
  • What previous work did they perform, and what was it like?
  • How have previous customers rated said contractor?
  • Is the contractor part of any accreditation?


What is a good method for removing mould?

One common approach is to use a bristle brush along with a cloth and a water-chlorine bleach solution. The solution should be three parts water and one part chlorine bleach. Glasses, gloves, and a face mask must be used.

How do you remove mildew?

To remove mildew, the same solution as suggested in the first FAQ answer should be employed. The same safety equipment should also be employed.

What happens if my home has toxic black mould?

In this case, you should hire a professional to remove the mould. It would be best if you did not do this on a DIY basis as this could prove very dangerous.

Can you fully remove mould from a home?

In truth, it is quite difficult to truly eradicate mould from a property, although with the right steps taken, the issue can be minimised to the point that it is unlikely to arise again or at least is unlikely to do so any time soon. This, of course, means that the source of the moisture must be dealt with too.

Can you fit wallpaper over mould?

You should only do so if the wallpaper paste being used to install the wallpaper has a fungicidal treatment. The necessary safety equipment should still be used before and while you lay fresh wallpaper. It is still preferable to safely remove the mould first, however.
