Cost Factors of Installing Garden Decking

When evaluating garden decking costs, there are various things you need to consider. First, you need to look at the condition of your terrain and determine whether it is flat, as sloping or difficult terrain will have a major impact on the cost.

The size of your garden will also have a massive effect on the price, as the larger your garden is, the more materials you will need. Larger decking will also take much longer, resulting in increased labour costs, as professional installers usually charge an average of £33 per square metre.

example of garden decking

The material you choose is also a massive price factor, as some decking materials are more expensive than others. So, if you have a low budget in mind, you may want to stick to timber decking, which typically costs around £1,000 to £1,500 to install.

Which is better for a family garden, decking or a patio?

"Decks are quicker to construct, resting on top of raised joists that can be elevated to make the most of a view. Unlike patios, they're suitable for uneven or sloping ground and most materials are more forgiving underfoot if kids take a tumble."

However, if you are thinking long-term, you may be better off with composite decking, which is more expensive, with prices up to £10,000 for larger gardens. While this may seem steep, you will get your money’s worth as this can last up to 30 years.

If you already have decking in your garden that needs to be replaced, you will also need to factor in the replacement costs. It may be that you only need some of your decking replaced, which can cost around £300; however, for a full replacement, you should expect to pay about £4,000 or more.

Planning and Installation

Planning Your Garden Deck

Planning your garden deck is a crucial step in ensuring that your outdoor space is functional, safe, and aesthetically pleasing. Before you begin, consider the following factors:

  • Size and shape of your garden: Measure your garden to determine the available space for your deck. Consider the layout and how the deck will fit into your overall garden design.
  • Type of decking material: Decide whether you want to use softwood, hardwood, composite, or PVC decking. Each material has pros and cons, so choose one that fits your needs and budget.
  • Budget for the project: Set a budget for your garden decking project, including materials, labour, and any additional features like railings or lighting.
  • Purpose of the deck: Consider how you plan to use the deck. Will it be a space for dining, lounging, entertaining, or a combination of these activities?
  • Local building regulations and planning permissions: Check with your local authority to ensure you comply with any building regulations and obtain necessary planning permissions.

Take time to research and gather inspiration from various sources, including online platforms, magazines, and showrooms. Create a sketch or drawing of your desired deck design, including the location of stairs, railings, and other features.

This will help you visualise the final result and make any necessary adjustments before starting the project.

Installation Process

Installing garden decking involves several steps, which you can find out about in our step-by-step how-to install decking guide.

decking frame

The installation process for garden decking typically involves the following steps:

  • Preparation: Clear the area of debris, vegetation, and obstructions. Ensure the ground is level and stable.
  • Groundwork: Lay a foundation of concrete or gravel to provide a stable base for the deck. This step is crucial for preventing future issues like sinking or shifting.
  • Framing: Construct the frame of the deck using joists and beams. Ensure the frame is level and securely anchored to the ground.
  • Decking: Install the decking boards, ensuring they are securely fastened to the frame. Leave a small gap between boards to allow for expansion and drainage.
  • Railings and balustrades: Install railings and balustrades to provide safety and support. Choose materials that complement your decking and overall garden design.
  • Finishing touches: Add decking screws, nails, and other finishing elements to complete the deck. Consider adding features like lighting, planters, or seating to enhance the functionality and aesthetics of your garden deck.

Building Permission for Decking

If planning to build a DIY deck, note that building regulations can be an issue even with small decks. It is always worth checking with your local authority before you spend any money on decking or begin any construction.

If you are going to build a substantial deck, keep neighbours informed and on-side from the start and be prepared to alter your building plans if they object.

decked balcony

Building regulations for decking only require you to apply for planning permission if your decking is over 30 centimetres high. You may also need to apply if your decking or other extensions take up more than half of your garden space, as this is classed as a major alteration.

If you do fall into the above categories, then you should expect to pay around £243 for planning permission. If you fail to pay this, you will be fined and you may also face issues with your local council or neighbours.

Costs of Maintenance and Cleaning

Garden decking will require regular maintenance, the degree of maintenance required depends upon a number of factors such as the quality of the material used, the construction and the location. Well designed and constructed timber decking should last 15 years or more with no requirement to apply preservative treatments as long as basic maintenance is carried out.

Fortunately, the maintenance required is pretty simple, regular brushing to remove organic debris plus perhaps a water repellent coating used to nourish the wood every other year. However, any decorative stains will also need to be refreshed to maintain their appearance every few years depending on usage and weather.

When maintaining and cleaning your decking, it is important to understand the level of maintenance required for different materials including:

Softwood and Hardwood

This requires yearly maintenance including sanding, staining, and sealing which would cost around £10 per square metre. You should also try to keep on top of it by cleaning it with a decking cleaner which costs around £6 to £15. This will help to keep the wood’s natural colour, making it appear brand new.

IPE wood

This type of wood is low-maintenance so would only require you to oil it once a year. The cost of decking oil is around £30 for five litres worth.

Composite, PVC and Trex

Composite, PVC and Trex require a simple cleaning procedure which involves soap, hot water and a soft-bristle brush. You should try to clean it a few times a year including after installation and once or twice in spring and autumn. The only cost you may incur is replacements costs, as unfortunately composite cannot be sanded to remove dents, It must be replaced which could cost up to £66 per square metre.

You should also consider additional repair costs, such as:

  • Damaged deck boards - £950
  • Loose stairs - £100 to £250
  • Mould and rot - £150 to £450
  • Stain and seal - £7 per square metre

These repairs can be conducted by you or a professional, although for the latter you will also need to consider the labour cost which is usually around £300 for repairs.

Garden Decking Removal Costs

If you require new decking or want to get rid of your decking altogether you may need to call in a professional or you could also do it yourself. If you opt to do it yourself you may want to hire equipment to assist you. A shredder for example would cost around £100-£200 a week but would reduce waste removal costs.

To remove your decking, you should start by removing the stairs and railings with a drill or electric screwdriver. You should then move onto the legs and feet which will most likely be secured with concrete, although they can easily remove using a shovel.

If your decking is fairly new, the concrete may be harder, so may need to hire a tractor or a similar vehicle to get the job done which can cost around £100 a day.

pile of decking boards

Many people prefer to hire a professional for the job, which would take around 2 to 7 hours and could cost around £100 to £500. While this may seem expensive, it may be worth it in the long run as you can install your new decking quickly while also avoiding any mistakes made when doing it yourself.

Can You DIY Decking?

While it’s possible to DIY decking, it’s not recommended unless you have extensive carpentry experience and knowledge of local building regulations. Decking installation requires specialised skills and equipment, and mistakes can lead to safety hazards and costly repairs.

However, if you’re determined to DIY decking, here are some tips to consider:

  • Start with a small, simple project: Gain experience and build confidence by starting with a smaller, less complex decking project.
  • Research and follow local building codes and regulations: Ensure your project complies with all relevant building codes and regulations to avoid fines and safety issues.
  • Choose a decking material that is easy to work with: Composite or PVC decking can be easier to handle and install compared to hardwood or softwood.
  • Invest in quality tools and equipment: Accurate and safe installation requires the right tools. Invest in high-quality tools to make the job easier and more precise.
  • Consider enlisting the help of a friend or family member with carpentry experience: Having an extra pair of hands and some additional expertise can make the project go more smoothly.

Remember, DIY decking can be a cost-effective option, but it’s essential to prioritise safety and quality to avoid costly mistakes and potential hazards. If you’re unsure about any aspect of the project, it’s always best to consult with a professional.

Hiring a Garden Decking Installer Checklist

Before you hire someone to install your garden decking, there are some things you should consider. Below is a checklist for you to follow when you're searching for a garden decking installer.

  • Don't hire the first business to give you a quote. Shop around, even if the price is low, you should compare multiple quotes.
  • Ask your garden decking specialist for references and photos. It's important to ensure that your installer is capable of the job before you commit. Seeing photos of previous work will not only allow them to demonstrate their ability but will also give you peace of mind.
  • Ensure you get a written agreement in place for the work that you need. A written agreement will give you a clear outline of what the job includes and a breakdown of the costs. This could also allow you to cut costs by doing the jobs you think you could do yourself.
  • Check if your decking installer is insured and holds the relevant liability for any unexpected damage to your property.
  • Remember to get a written receipt after making any payments. This will protect you from any disputes in the future.

FAQs

Do I Need Planning Permission?

Many think that permissions are not required with garden decking, but this is not always the case. Consent is required prior to building a deck where the deck platform is more than 300mm from the ground, If covers over 50% of the garden area or where the deck is situated within 20 metres of a highway.

In addition, building regulations should be assumed to apply to every structure that requires planning permission. Property owners should always check with their local authority regarding planning.

Can I Install A Hot Tub On My Garden Decking?

Probably not, unless the deck was purpose designed by a structural engineer to take that weight. If planning to add a hot tub then you must discuss this with the contractor before building the deck.

If adding a hot tub to an existing deck, then you must contact a specialist builder to check the decking will be able to safely take the additional weight.

Do I Need A Balustrade?

Balustrades are not just a decorative feature, they are also a safety barrier and can be useful as supports for less able bodied persons. If the deck is raised above the ground then some sort of balustrade should be used to prevent a fall.

The height of the balustrade depends on how high the deck is above the ground: For lower decks up to around 2 feet (600mm) above ground level, the balustrade height should be around 3 feet (900mm), but for higher decking, 1100mm balustrade needs to be used.

How Do I Prevent My Deck From Being Slippery?

You may find that your decking becomes slippery for various reasons. This could be caused by mould, algae or moss growing on your decking. To prevent anyone slipping over and injuring themselves, you should try to keep your decking as clear as possible by sweeping and cleaning it regularly, especially after any bad weather.

You should conduct a thorough clean once a year using a pressure washer with a broad fanning nozzle, which will cost around £90 to £200. Using this tool will allow your timber decking to become slip-resistant and will also provide extra traction.

You can purchase commercial cleaning products for your pressure washer or make up your own using ammonia-free laundry detergent, bleach and water. If you cannot afford or access a power washer, then a wet mop or a pump sprayer will suffice.

When Will I Need To Replace My Decking?

Timber decking tends to last around 10 to 15 years depending on how well it is looked after. After this, you will need to decide if you want it to replace it or choose an alternative material like composite, which can last around 25 to 30 years. Again, it can last longer if you maintain it properly, so the more you keep on top of it the more years you will get.

How High Can Decking Be?

To avoid applying for planning permission, you will need to make sure that your garden decking is no higher than 30cm off the ground. You should also make sure that the decking extension takes up no more than 50% of your garden, as this will also require planning permission.

Is Garden Decking Expensive?

The cost of decking will depend on several factors, including the size of your garden, the materials you use, your location and more.

The price of your decking will depend on your own budget, although a typical price is usually around £80 per square metre including material, installation, labour costs and more. In comparison to a patio, decking is usually known as the more expensive of the two, although, patios can involve a complicated installation process which would outweigh the costs of decking.
