Decking Wood Prices
How much does decking cost (by itself) in 2021?
|Type of Decking||Cost Per Metre|
Excluding all other costs, the cost per metre of softwood decking should be between £3 to £6.
Other types of decking are usually more expensive, with hardwood decking costing about £4 to £10, composite wood decking priced at around £8 to £12, and uPVC decking in the range of about £5 to £10.
Do not confuse the cost per metre squared with decking prices per square metre.
To cover an area of 20m2, the cost of medium-quality decking wood would be around £400 to £550. For a larger area of 40m2, it would cost between £700 and £900.
What Are the Additional Costs of Decking Installation?
What additional costs might you need to pay when having new garden decking installed?
Here are a few you should be aware of.
Garden Maintenance Prices
A gardener may charge anywhere in the range of £20 to £110 per hour.
Howvever, most gardeners will have a flat rate covering at least two hours.
As a result, you can expect to pay between £40 and £220 to have garden maintenance undertaken by a professional. It will likely fall somewhere in the lower area of this range.
Garden Waste Removal Cost
Garden waste removal will likely take about 45 minutes and cost you somewhere in the range of £100 and £200.
How much garden waste you wish to have removed will ultimately determine the total cost.
For example: To have about 300kg (20 bags) of waste removed may cost around £80 to £110, while it should cost about £200 to £230 to have 900kg (60 bags) of garden waste removed.
Weed Proof Membrane Cost
You could have a weed proof membrane installed to protect your decking from garden weeds (like broad-leaved dock and nettles).
This will likely cost about £30 per pack. It will also require additional labour, which may cost about £20 to £40 for an hour's work (assuming it is on top of an ongoing work schedule).
Installing Decking Steps
Another addition to your decking which you could have installed is decking steps.
The cost of decking steps may be anywhere between £50 to £215. The labour costs depend on how long the job will take, but most people will charge about £20 to £40 per hour.
Decking Installation Cost
What are labour prices you should expect to pay to get a deck installed in your garden?
Before we get to them, keep in mind that these are average estimates. Your whereabouts in the UK will strongly impact the cost of decking installation.
The labour costs of having softwood decking installed for a 15m² area will be roughly £300 to £400, while having hardwood decking installed in the same area will cost twice as much (around £600 to £800).
Composite decking installation costs will be about £500 to £620 for a 15m². To cover the same area with uPVC decking will cost hundreds less (roughly £300 to £330).
For a larger area of 20m², the price to install medium-quality timber decking would be around £1000 to £1250. For an area twice the size of this (40m²), it would cost roughly £1800 to £2200 to get the decking installed.
How Long Does It Take to Install Decking?
For this section, we will discuss the durations it takes to install the various types of decking, namely softwood, hardwood, composite and uPVC.
The table below breaks down how long it should take to install various types and sizes of decking in your garden.
|Type/ Size||Installation Time|
|Low-cost decking boards (20m²)||2-3 Days|
|Low-cost decking boards (40m²)||4 Days|
|Medium-priced decking boards (20m²)||2-3 Days|
|Medium-priced decking boards (40m²)||4 Days|
|Premium-priced decking boards (20m²)||2-3 Days|
|Premium-priced decking boards (40m²)||4 Days|
However, it could take longer than this.
Factors that impact the time it takes to install decking include the:
- Size of your garden.
- State of the decking area (as a poor decking area may need additional groundwork or preparation).
- Ease of access to your garden.
Types of Decking
We'll now go through the different types of decking that you can get in more detail.
Each of the subsections below goes through what each type of decking is, associated costs, as well as the pros and cons. Once again, labour costs are based on an area of 15m².
Softwood Decking Costs
Softwood decking is made from trees like spruce and pine which are coniferous, evergreen trees. Roughly 4 in 5 types of timber are softwood and are often used to make softwood timber decking.
The supply cost for softwood decking is around £3 to £6 per metre, while the labour costs of having this type of decking installed will land around £300 to £400. Softwood decking products tend to be the cheapest decking available.
- Cheaper decking type.
- Easily installed.
- With pressure-treated softwood, you can anticipate a long-life expectancy.
- More environmentally friendly than hardwood.
- Unsuitable for areas with high foot-traffic as it can fade with time.
- Regular maintenance will prove necessary for softwood decking.
- Not as durable as hardwood.
Hardwood Decking Costs
Hardwood decking is made from trees that are deciduous and have a slow growth rate. Maple and European Oak are examples of different hardwood types.
You can expect hardwood decking installation costs to be around £600 to £800. The supply costs of hardwood are usually around £4 to £10 per metre.
- High quality type of decking.
- Very durable.
- More fire-resistant than softwood decking.
- Unlimited design options.
- May prove more difficult and time consuming to install.
- An expensive type of decking.
- Needs regular maintenance.
Composite Decking Costs
Composite decking comprises both wood and plastic materials. You can expect to pay around £8 to £12 per metre of it.
Composite decking installation costs will likely end up in the range of about £500 to £620 - which is more expensive than softwood or uPVC decking products.
- Available in a wide range of colours and textures.
- More expensive than softwood or uPVC decking.
- The colours of composite decking cannot be changed.
- Dark composite decking colours are prone to fading with time.
uPVC Decking Costs
This type of decking is made entirely from plastic. uPVC decking installation costs will be about £300 to £330, with uPVC material costs usually between £5 to £10 per metre.
- One of the cheapest types of decking materials.
- Highly resistant to becoming slippery - even during particularly wet weather.
- Doesn't rot.
- uPVC decking doesn't require maintenance.
- May not be the type of aesthetic you are looking for.
- More difficult to install.
- Can become particularly hot during the warmer months, which may mean that it's not suitable to walk on without footwear (or for pets to walk across).
How Much Does Repairing Decking Cost?
In this section, we break down the cost of different types of decking repairs.
Two common decking repairs include fixing rotten decking boards and repairing decking joists.
Rotten Decking Boards
To fix decking boards that have been damaged by rot, the relevant pieces of wood will need to be taken up. The planks should then be turned upside down before being treated with a wire brush to remove heavily eroded pieces.
The decking boards may then be soaked and treated again with a wire brush once they have dried. A product like CPES may also be used to improve the wood’s condition.
Filler may also prove necessary to fill where old, worn pieces of wood had been removed. The decking boards will then need to be returned to their original place.
A professional may use this approach. However, they might recommend that you replace the decking boards. This can sometimes be a quicker and lower cost option than repairing them.
To have new decking boards installed may cost anywhere from £3 to £12 per metre in length - with a professional charging a minimum of £40 to £50 assuming 2 hours or less of work. Based on this, to have five decking boards replaced might cost you about £80 to £90.
Repairing Decking Joists
Decking joists can be repaired by having rotted areas removed after a short inspection.
Sealer should then be applied before the joist is reinforced. The reinforcing of the joist must then be secured.
If you wish to hire a professional to install replacement decking joists, you can expect the cost for pinewood to end up at around £5 to £7, £9 to £11 for softwood, and £14 to £16 for hardwood.
The labour costs will likely come to around £20 to £25 per hour. A two-hour flat rate minimum charge will likely be charged by the tradesperson.
How Much Does Decking Maintenance Cost?
For this section, we will discuss the costs involved in performing various types of decking maintenance.
Paint, Stain, or Oil Decking
While painting the decking can help to bring vitality and life to it, staining is specifically designed to paint a colour onto the wood. Oil is used to apply an appropriate finish and give a glistening, aesthetic look to your decking.
Late spring or early August are the best times to paint, stain, and/or oil decking. You should have your decking stained stain at least every two years. Your decking should be oiled every 6-12 months. In terms of painting, it may only be required every several years.
A painter will charge a minimum of about £27 to £37 (two-hour flat rate) and an additional £14 to £18 per hour after the first two to paint decking.
Total labour costs will depend on the size of your decking, the ease of access to your garden, and your whereabouts in the UK.
The supply costs will be added to the labour costs if performed by a professional or will prove the sole cost if you undertake the work by yourself.
The supply costs to paint a decking with an area of 20m² will probably come to about £30 to £120, as 2-6 litres of paint will be needed. The decking should be painted 1-3 times.
The wood stain paint supply costs for the same area of decking will likely cost you about £40 to £200. Two coats of stain paint should be applied to the deck. A painter will charge the same for this type of work per hour (in terms of the labour costs) as mentioned above.
For every square metre of decking, 1 litre of oil should provide you with enough for two coats. 2-3 oil coats will be needed. Hence, you may need 20-30 litres of oil to fully cover a deck if it has an area of 20m².
The total cost for 20-30 litres of oil will likely end up around £80 to £240. The labour costs will once more be around £14 to £18 per hour if performed by a painter.
Deck cleaning may involve a full wash of the decking and efforts to remove rotted pieces of wood, other debris, and undesired marks that have appeared on the deck. It’s best to clean the decking in the spring or autumn and when the temperatures are consistently above 11°C.
Your decking should be cleaned about once a year. The labour costs of deck cleaning will likely come with a minimal two-hour charge of about £50 to £100 while the cost per metre squared for the clean will likely be around £1 to £2.
This means that to have a decking cleaned which is about 20m² will cost roughly £70 to £140. If you wish to perform the job yourself, the supply costs will vary based on what materials you require.
This will depend on how much of a clean is needed. A pressure washer will help you to wash your deck effectively and will cost you around £80 to £200 to buy one. Other tools you may choose to buy include a deck cleaning solution (£10 to £20) and a scrubber brush (£5 to £8).
When decking has become weathered and worn, it should be sanded to even it out and remove imperfections.
It is best to sand your decking in the spring or autumn and during a time when there is little to no rain forecasted for a several day period.
Your decking should be sanded before being stained. This means that sanding it every 2 years prior to staining or otherwise when needed is required.
If you wish to have your decking sanded, it will probably cost you £14 per square metre with a professional charging £40 to £50 as a flat rate and then around £20 to £25 per hour thereafter.
For a 20m² decking, it’s probably going to cost you about £400 to £500 in terms of the total labour costs.This assumes that the job will take around six and a half hours.
If you wish to sand the deck by yourself, you’ll likely need to spend anywhere from £10 to £50 on supply costs. Of course, how much sandpaper you’ll need to fully sand your decking will depend on the type of decking you have and the area it covers.
How Much Does It Cost to Remove Decking?
You may choose to remove decking because you have no use for it or if you wish to replace it with another surface such as paving slabs or artificial grass.
A professional will probably charge you about £100 to £500 to remove your decking. You may also choose to hire a skip for roughly £50 to £200.
How large the skip needs to be will depend on the size of the decking you want to have removed. You can dispose of decking with a skip or through a ‘man and van’ service.
Q: How much decking do I need?
A: The number of decking boards you’ll need will depend on the size of the area you wish to cover. You can utilise a decking calculator to figure this out as well as to calculate various other details such as how many joists and posts your decking will require.
Q: What is composite decking?
A: Composite decking is an option which is made of both plastic and wood materials.
Q: How long does decking last?
A: Decking may last anywhere from 15 to 30 years - if well maintained.
Q: Which wood is best for decking?
A: Redwood and cedar woods are among the best types for decking.
Q: What is uPVC decking?
