How Much To Remove a Chimney Breast?

Looking for chimney breast removal costs?

Removing a chimney breast is something homeowners might be interested in doing during a remodel of their home.

It is, however, a very large job and is the type of project that should only be performed by a professional chimney specialist, because the chimney breast is just a small portion of the entire chimney.

chimney1

Because of this, you're going to find it's essential to hire a contractor with the proper equipment, knowledge, and experience to remove a chimney breast.

Depending on the size of your chimney, more than one contractor may be required to complete the job effectively.

So, what will the overall chimney breast removal costs depend on?

The costs involved with removing a chimney breast will vary depending on whether or not you’re looking to remove the entire chimney. It will also depend on whether you are removing the chimney breast alone or whether you are removing the chimney stack as well as the breast.

The cost to remove an entire chimney without the stack is, on average, around £2,200 to £2,400, and the average price for removing the entire chimney stack with the breast is around £3,000 to £3,500.

Is a Gas Safe Registered engineer required for a chimney breast removal, or would it depend on different factors? If so, what might it depend on?

"You would normally only need a Gas Safe Registered engineer if you had the gas supply to a previously installed gas fire, or one currently installed within the chimney area."

Additional Chimney Breast Removal Costs

Several additional costs may arise when it comes to removing a chimney breast.

Here's a list of some of the additional costs you may need to think about when it comes to removing your chimney breast:

You should also consider the cost of materials required to re-decorate after the job is complete.

chimney2

If you're thinking of hiring a painter and decorator to carry out the re-decorating work for you, then you can expect to pay them around £8 to £15 on average per hour.

You may also need some roof repairs if you've had your chimney taken away as you'll need something to patch the gap left behind.

The cost of replacing roof tiles depends on your tile material - with slate being more expensive than clay or concrete - but typically costs around £200 for five tiles.

Roof repair costs are likely to be one-off fees, however, so you typically won't need to add this to your ongoing fees if you have a competent roofer repair your roof the first time.

Below you will find a list of several cost-affecting factors that may alter the overall price you pay to have your chimney breast removed:

Type of Removal

The type of removal can affect the overall cost of removing your chimney breast. If you are looking to get your ground floor chimney breast removed alone then this will cost around £1,500 to £1,750, whereas the cost to remove the entire chimney breast and stack will cost about £3,000 to £3,500.

Size of Chimney Breast

The size of the chimney breast will affect the cost you will pay to have it removed. A larger chimney breast will take longer in total to remove than a smaller one, and so this will end up costing more.

Scaffolding Use

If scaffolding is required to complete the job, then you can expect the job to cost a lot more. On average, scaffolding hire is going to add costs of around £3,000 to £4,000 more onto the total cost of the job.

How Much Does Removing a Chimney Breast Save You?

After removing your chimney breast and stack, you can enjoy long-term savings as you no longer have the need for chimney maintenance costs. In total, you can look to save between £1,200 to £2,570 in one-off costs, and an additional £60 to £150 in regular annual costs.

Let's take a closer look at the potential savings related to chimney breast and stack removal:

Chimney Sweeping Costs

Without a chimney, there's nothing to sweep. The cost of chimney sweeping ranges from £60 to £150 depending on your chimney type, with the biggest savings coming from homeowners removing lined and unlined stove chimneys.

Chimneys should be swept around once a year, or more depending on your usage, saving you a few hundred pounds each year.

Chimney Liner Costs

Chimney liners cost between £600 to £1,000 - so cutting out that replacement cost can be a welcome change from your outgoings. While this is often a one-off or irregular cost, over a 30-year period, you can look to save anywhere from £1,800 to £3,000, based on a chimney liner replacement every 10 years.

Replacing Chimney Leadwork Costs

Lead flashing is used where the chimney connects to your home's roof. If you've removed your chimney, there will no longer be a need for chimney leadwork repair costs - typically between £350 to £460, or £700 to £920 if you need scaffolding for access.

How much would it cost to point a chimney stack and a half on a semi-detached house, plus remove chimney cowls and replace with new cowls? There is also a tile that has been dislodged and a small leak on the back of the house.

"£500 for pointing, new cowls and tiles sorted. I would need to see where leak is and see what needs to be done before I can give a quote on that."

Fixing Penetrating Damp Costs

Although chimney stacks and breasts can add warmth and a favoured internal feature to many homes, having a gap running down into the interior of your home does come with its challenges. For homes with recurring penetrating damp issues stemming from the chimney, it can be a relief to remove the cause and correct the damp.

Instead of paying out regular penetrating damp repair costs - anywhere from £250 to £650 for a single wall depending on house size - you can remove the chimney breast and stack and have one penetrating damp treatment to resolve the issue.

What's Involved in Removing a Chimney Breast?

Removing a chimney breast is an extensive and challenging job that requires a lot of work. External chimney stack removal is typically completed outside of the home and, therefore, will not cause any damage to the internal decorations.

Removing the internal chimney breast will, however, create a lot of mess. A lot of dust and debris will fly away during the process, so the room should be protected accordingly.

Also remember that any plumbing, gas, and electrical services that link up to the chimney breast should be isolated and altered before the job can begin.

If the upper sections of the chimney are going to remain, then these will need to be held up with Strongboy steel wall supports before you can begin to remove the chimney breast below.

This support will need to be kept in place before a new permanent fixed support is put in place. The permanent support will need to be designed by a qualified structural engineer.

You may also need to remove the chimney stack. In some cases, this part of the chimney may be part of a shared central chimney system. With this in mind, you may need to adhere to the 1966 Party Wall Act. This will make the overall job more complex, and it will take longer to complete, which can add on some considerable costs.

chimney6

Once the chimney has been broken down and removed, you will need to clean up the mess and re-plaster the wall ready for re-decorating. Removing a chimney generates a lot of dust and debris, and so this part of the job can take a long time. If you are employing a plasterer or decorator, then this will also add some extra costs to the overall price of the job.

Along with structural support, you will also need to have appropriate insulation fitted, and the area will need to undergo damp-proofing. These costs are usually included in the overall price; however, this can vary depending on the type of materials that are used and the complexity of the job. The type of materials that you choose will likely depend on your specific needs and your budget.

Each individual part of the job should be carried out by a qualified and experienced tradesperson, and they should adhere to all of the building regulations and health and safety requirements.

My semi-detached house has a chimney in the living room and kitchen. Two upstairs rooms have the breast, but it's been removed in the kitchen. Can I get the chimney breast in the bedroom upstairs removed?

"Yes, this is possible to do, but we will need some structural calculations and steelwork to support the chimney stack in the loft space in order to fully remove the breasts from the house."

Planning Permission for Removing a Chimney Breast

Planning permission for removing a chimney breast is only likely to be needed if your building is listed or located within a conservation area.

However, it is advisable to contact your local council who will provide further information on whether you need planning permission for your particular chimney removal job.
