House Demolition Cost Guide

There are many reasons as to why you would demolish your house. The most typical is that you want to rebuild with something new. This article addresses various aspects on house demolition but most importantly will outline the house demolition cost that you need to be aware of.

You can level a small structure such as a garage or a shed by yourself. However, that being said, a house demolition is a major job that involves removing the building and all its contents, including walls, floors, ceilings and fixtures. It is advisable to hire a specialised demolition contractor that is familiar with the required legislation and has the necessary equipment. It can be a very difficult and dangerous task for homeowners to undertake without expert help.

We will also look at the three different ways of demolishing a structure, as well as how they might be combined to create a customised approach. We will also discuss demolition regulations and the limitations imposed by the government and local authorities. Finally, we will address the steps involved in demolishing a house.

How much does it cost to demolish a house?

The house demolition cost is calculated using the building’s floor area, but other factors may affect the final price. This article will examine the prices charged by professional demolishers and how they are determined. 

The cost of demolishing a detached house varies depending on its size and other considerations. A load-bearing wall typically costs between £1,000 to £5,000 to remove.

However, the cost of demolishing a complete property ranges between £7,000 to £35,000. In comparison, the cost of demolishing a conventional single garage is between £1,000 and £5,000.

The following table lists house demolition cost from specialist contractors around the UK. These costs are presented in square metres but don’t include the other factors discussed later in this guide.

House demolition cost considerations

Demolishing your own home might seem like an attractive option, but there are several legal constraints to consider. It is therefore typically more prudent to hire a demolition contractor who has the required tools and can help you understand the relevant regulations.

The cost of a house demolition depends on several factors, including:

• The size of the house (and its foundation)
• The location of the house
• Ease of access to the property
• How prepared the structure is for demolition (e.g., does it have asbestos or other hazardous materials?)
• Any hazardous material used?
• Any trade associations involved?
• Salvage

Let’s look at each in turn…

Size of the house / property

Before you begin the demolition process, you need to know how many rooms your house has and what size it is. This will help you determine what category of home demolition costs you should be considering. 

For example, if you have a two-story house with four bedrooms and three bathrooms, then it’s safe to say that its square footage is going to be larger than a single-story ranch style one bedroom house with no bathroom.

A good rule of thumb when determining your home’s square footage is this: multiply the length by width (plus any additions such as porches or sunrooms). This will give you an approximate idea of how much space there is in terms that are sometimes easier for people without math backgrounds (or those who haven’t been paying attention) can understand.

Location of the house / property

Location is also a factor in determining house demolition cost. For example, if you live in the middle of nowhere and are having your entire home demolished, expect to pay more for all aspects of the job.

In addition to location being important for transportation and access issues, it can also impact your overall project budget by increasing labor costs due to unforeseen challenges (such as working with frozen soil) or requiring more equipment than expected (like using cranes instead of backhoes).

Accessibility

Accessibility is a critical aspect of any home demolition project. It determines the ease with which you can access a property, and it impacts the costs you’ll incur during the demolition process. If it’s hard to get to your home, then you’re going to have to hire an excavator or crane operator as well as pay them overtime rates—and that will add up quickly.

If you want your demolition project to go smoothly and cost-effectively, assess accessibility before signing on with any contractor. Here are some tips for assessing accessibility:

• Consider the size of the equipment needed for the job (e.g., do you need a crane?)
• Think about how far away from your house is safe for heavy machinery (e.g., do not operate heavy machinery in front of neighboring houses)

Preparation

When you’re preparing for demolition, it’s important to follow certain protocol. You need to make sure all gas, water, electricity and drainage services are safe and then cap them off once they are disconnected from the home.

This may seem like a lot of work but it will save you money in the long run. If you don’t cap these lines and make sure they are safe before tearing down your house they could spring leaks or cause damage to other parts of your home that weren’t previously affected by the demolition process.

Hazardous materials

Depending on the materials used during the construction of your home, you will want to ensure that all hazardous materials are properly handled. 

These can include asbestos or lead-based paint and should be disposed of in a safe way. If you are demolishing a house built before 1990 and it has been in service for more than 10 years, consider commissioning an asbestos survey before demolition to determine if there is any asbestos insulation present.

You should also look for ways to properly dispose of these items as opposed to simply throwing them away with regular trash.

Salvage

Salvaging is the process of removing reusable components from an old house before it’s demolished. Salvage companies purchase waste materials, often at a discount and resell them to consumers.

This is not a job for the average homeowner, however; reputable contractors will already include the scrap value in their house demolition cost estimates without charging extra for salvaging.

Different house demolition methods used

There are several different demolition methods available, ranging from explosive to hand. You’ll need to consider which method is most suitable for your home and the surrounding area before deciding which way to go.

• Explosive demolition can be extremely effective at bringing down a building, but it is also noisy and messy. Using explosives will have a big impact on neighbours who live nearby, so this may not be ideal if you have neighbours who would prefer not to experience loud noises during their morning coffee or evening walk with the dog.
• Top-down demolition involves machines that cut through floors from top floor down until they reach ground level. This method can be useful if there is an existing basement under the house being demolished, because it allows for removal of all underground utilities such as water pipes without having to dig up large areas of soil before beginning work on removing walls inside upper levels of buildings being demolished (which would otherwise be necessary if using hand tools). 
• Hand demolitions tend not only require more effort than other methods but can also take longer than other options due their slower pace; however they do allow more flexibility when working around existing structures such as trees or ponds within lawns where these obstacles might prevent other options from working effectively

Applying for Planning Permission to Demolish a House

You generally won’t need to apply for planning approval unless you reside in a conservation area or a listed building. The size of the facility, the degree of destruction, and the nature of nearby structures, such as hospitals or schools, all influence planning approval. 

As a result, before beginning the project, you should get counsel from your local government. Typically, you must obtain demolition authority for the following buildings or structures:

• Memorials or sculptures placed outside.
• Buildings that are unsafe.
• Restaurants, pubs, and bars
• Theatres, music halls, and cinemas
• Structures in a conservation area.
• Listed structures

Building permission

You must give the local government at least six weeks’ notice before beginning a demolition project. Then, if required, they will specify the requirements you must follow. You must also follow some standard building codes. And those specifically dealing with asbestos removal and ingress of water.

Health and safety during a house demolition

The safety of everyone involved should always be your top priority. Whether you’re hiring a contractor to demolish the house, or you’re working on the demolition yourself, make sure to follow all necessary precautions at all times.

Public safety is of paramount importance when dealing with any kind of demolition. It’s important that pedestrians and motorists know that they’ve entered an area where there may be heavy machinery and other factors that could affect their normal movement patterns.

Safety for those involved in the demolition process should also be taken into account throughout the planning stages of your project. This includes making sure there are proper eye protection provided for anyone working around heavy machinery or other potentially hazardous areas.

Demolition Project Timelines

You can expect the demolition process to take anywhere between a few days and a few weeks, depending on the scale of your project. The time it takes will depend on many factors, including:

• The type of property you’re demolishing. A detached house will typically take one to two weeks to demolish; semi-detached or terraced buildings will take longer because of their additional structural support required by law (i.e., fences).
• The number of rooms in your home. Typically speaking, more rooms mean more work for the demolition contractors! It’s also worth noting that if there are no asbestos issues involved with your project, then this time frame can be reduced substantially since we won’t have to wait for building control approval before carrying out any work at all.

Steps involved to ensure a smooth house demolition

To comply with the requirements and maintain the worksite safe, you must follow the specified methods. Consider the processes for hand demolition and recycling recyclable materials, which is the most popular demolition method for residential homes.

• Check with the local authorities to ensure that no special permits are required.
• To schedule inspections, contact Building Control.
• Negotiate with your neighbours if required to comply with the Party Wall Regulations.
• Conduct an asbestos survey if the structure is old enough.
• Select a reliable demolition company. A member of the National Federation of Demolition Contractors is preferred (NFDC).
• All electrical, water, gas, and drain services should be capped and made safe.
• Install fencing to safeguard the place.
• Build a scaffold for the workers.
• Use authorised expert contractors to remove hazardous materials such as asbestos.
• Remove any recyclable elements, including electrical wires, kitchen and bathroom fixtures, plumbing supplies, doors, windows, and easily accessible wood.
• Remove the tiles and lead flashing from the roof.
• Roof rafters and floor joists, for example, should be removed.
• Remove and demolish bricks and concrete blocks.
• Concrete pads, foundations, and unnecessary drains must be removed.
