Chimney Breast Removal Cost 2022 : How Much Should You Pay?


If you intend to remove the chimney breast from your home, then you should know about the details regarding this process. Chimneys have a long history, and they have been used to provide warmth during the cold seasons through the centuries. The United Kingdom used to have a colder climate before the last century. 

The winter used to last for more than six months. However, with each passing day, the temperature is becoming higher due to climate change. Therefore winters are not as prolonged as they used to be. The constant change in the temperature is also encouraging people to alter their lifestyles and homes.

However, the modern interior design of the homes provides a more minimal outlook. These usually include an internal heating system. Therefore there remains no particular necessity for the chimney breasts unless somebody wants to please their aesthetic sense. Moreover, some people may find it overwhelming, and getting rid of them enhances the space in the house. 

Most people renovate and remove the chimney, and House Owners may also eliminate them when they put their homes on retail. The chimney breast removal costs are the same, more or less. Certain factors may impact the overall expenses. The chimney removal cost and process may depend on the labour you hire.

  • Similar to the ground floor chimney breast, you must ensure that the joists are not connected with the floor or ceiling of the loft. If they are present, then you must use joist trimmers.
  • You must temporarily support the bedroom floor and loft ceiling with a gallows bracket. As a result, the rooms will remain situated, and you will not crumple the rest of the house structure.

A Chimney Breast

A chimney breast is a region that consists of a stack and the hearth. The stack leads to the top of the house and is situated on the roof. It gathers the smoke from the hearth and releases it into the air. It is directly above the chimney flue. The Flue consists of the enriched gas and smoke which the fireplace ultimately emits.

The chimney breast occupies a vast portion of your room and is placed near the wall; however, the breast protrudes out.

Removing Chimney Breast: The Necessity

There are several reasons why people go for removing a chimney breast. Following are some of them.


Removing a chimney breast can help you receive an optimal amount of ventilation. Most homes constructed during the late 20th century do not have an option for the colder air to reach into the house. This causes the warmer air to remain trapped in the air pressure within the home, causing destabilisation. 

The influx of the cold air promotes a neutral pressure, and it is easier to breathe the air in such places. Once you discard the chimney, you can have neutral air and ventilation in your home. You will not feel suffocated or experience difficulty in breathing by getting a fresh and warm atmosphere. Moreover, the warm air that used to reach through the stack will remain after removing a chimney breast.


The chimney breast takes up significant space in your room. The old-style British homes do not already have cramped rooms. Therefore it can be challenging to adjust your furniture. As minimalist architecture becomes more popular, people prefer more house space. They can then utilise it for installing the decor. 

The chimney hearth is on the front of the chimney breast, and it protrudes out with an approximate measurement of 300mm. Moreover, chimneys commonly have brick hearths. These are usually dark in colour, which causes them to seemingly occupy more space.


Maintaining the chimney breast can be pretty tricky. You need to clean the chimney before, during, and after each season. It may even get blocked if something is stuck into the stack. 

You must also protect the stack and ensure that no bird falls into it. Bird nests are also quite common on the chimney stacks. Therefore, you must carefully remove them and place them securely. 

Once you kill the fire, you need to eliminate the debris in the chimney hearth. They may even create a distinct odour in your room. In such cases, you may opt for air fresheners to keep the room atmosphere healthy.

Moreover, you need to constantly invest in getting your chimney breast cleaned. Therefore removing the chimney breast saves you from this financial burden. You can add up the costs and then rest by removing the chimney breast altogether.

Altering the Architecture

Home renovation and giving it a new outlook are among the most significant motives for removing chimney breasts. There are several replacements for chimney breasts that are prevalent in the market. 

You can get a gas fireplace to replace it. These have a live fire burning with a minimal and delicate outlook. Moreover, the gas fireplace also provides an aesthetic sense to the entire interior. The electric fireplace is also quite common and may even offer the feature of different fire colours that you can switch on as you please. The electric fireplace is also more efficient and does not produce exhaust gasses. 

It can heat the room more instantly than the chimney breast and other fireplaces. These are cost-effective and low maintenance, and you do not have to thoroughly clean them each season. Therefore, fireplace removal can allow you to design your home according to your preference and modern styles.


As your chimney breast ages, chances are that it will become damp and may even get moulds. In such a case, fireplace removal becomes the most optimal solution. As your home encounters moisture and rain, it becomes wet. 

Furthermore, there must be sufficient air availability to dry it. The stack can quickly get dry as they are present on the outside. However, if the vertical lining that leads to your home becomes damp, it does not get rid of the moisture instantly.

Moreover, if the ventilation in the room is inadequate, the chances for mould formation also increase. Therefore, you must carry out specific protocols to keep your chimney in pristine condition. 

In some cases, you may also notice the patch formation on the chimney’s structure. If you see the distinct yellow and brown regions, chances are that the entire chimney breast has moulded. This is also a result of increasing dampness. 

Fixing such chimney breasts requires a considerable investment and is quite tricky. Moreover, some moisture remains within despite the best attempts. In such scenarios, it is ideal for you to remove a chimney breast.

Crack Formation

Over time the mortar of your chimney may start to have specific gaps. These are the cracks that form due to several reasons. These include poor maintenance, accumulation of frost, and freezing temperature. 

The cracks may compromise the overall integrity of the chimney breast. It may even start crumbling, and you may lose certain portions of the chimney. To rectify such damages, you need to insert plasters and bricks. However, this will not ensure that the chimney will not have cracks in the future. Therefore, removing a chimney breast is better instead than constantly mending it.


It is common in chimneys that use wooden designs. They use thick wood for supporting the breast and the hearth. However, these are more susceptible to damage due to increasing years and the weight to hold these parts. If your fireplace has such components, you should consider removing it.

Factors Affecting The Costs Of Removing A Chimney Breast

Size of the Hearth

Hearth usually occupies a lot of space. These have dimensions of 330x160mm. Therefore removing them will require more hammer work. The bricks at this point are strongly associated with another. So the labourers have to exert extra effort in breaking the hearth to remove a chimney breast.


Scaffolding is an important aspect that you need to remove a chimney breast optimally. If you leave the stack intact, you can put the scaffold tower on different floors as you remove a chimney breast. However, if you discard the stack, you can use external scaffolding with the help of a professional.

Heavy Load

Chimneys are one of the pieces of architecture that bear a significant load. They carry the entire stack till the breast through different storeys. Therefore they hold a lot of pressure. It is efficient to appoint a structural engineer. 

They will identify the point of highest load-bearing. Afterwards, they will install the joists and brackets to temporarily hold the weight as you remove a chimney breast.

Construction Protocol

Some chimneys support joists on every floor. These will require you to add more brackets and steel supports. The older the chimney is, the deeper its role is in maintaining the house’s structure and holding the ceiling and floors.

Removal Protocols and Guidelines

There are specific guidelines and methods for removing a chimney. It is necessary to follow them before you begin the process.

  • The chimneys in most houses support the ceiling and floors. In some regions, there is a unit where the chimneys are at the junction of a pair of houses. Disturbing such chimneys may interfere with the integrity of all places. Here, the Party Wall Act of 1996 is also applicable, which prevents you from interfering with the property and rights of your neighbours.
  • Some mechanisms at the floor and ceiling level ensure the absence of dampness in your house. You may interrupt this process when you wreck the walls and floor to remove a chimney.
  • You must also keep fire protection nearby. 
  • Soundproof mechanisms in the walls and ceilings are necessary when you live in a congested neighbourhood. Removing a chimney may also disturb the soundproofing.
  • According to the latest guidelines, all the floors and rooms in your home must have ventilation. After removing a chimney, you must ensure that each room has ventilation of 800 mm2.

Why Should You Hire a Professional?

Removing a chimney is not a simple task. There are a lot of factors that you need to consider before you can proceed. You need a structural engineer to help you maintain the floor and ceiling support. 

Moreover, you need manpower to conduct the entire process. While you can assist in removing the bricks, you cannot perform the complete removal unless you are an engineer.
