Let's go!

When choosing a timber for cladding, cost is usually a factor. This includes the upfront cost, of course, as well as maintenance and longevity, all of which add up to the return on investment (ROI) of your new outdoor cladding. Make sure you are making the best choice for your hard earned cash with this guide to long-term ROI for hardwood vs softwood cladding.

What is ROI?

In financial terms, ROI is often considered as the financial gain on an investment. For instance, if you spend X amount of money on an advert, how much extra can you expect to earn in sales? However when looking at timber cladding, the story’s a little different.

For the purpose of this guide, we will look at ROI from the perspective of how long you can expect your cladding to last, and how much maintenance you will need to invest to keep it looking its best.

ROI of Hardwood vs Softwood Cladding

Softwoods, such as Cedar and Larch, often come with a lower upfront cost than hardwoods (particularly tropical hardwoods), making them appealing for projects on a budget. We do not disagree with this. The right softwood offers excellent performance when properly maintained, but that is the keyword here: maintenance.

Many softwood species (though not all) need more frequent staining, sealing or protective treatments than tougher hardwoods. They also typically have a shorter lifespan. Our stronger softwoods, which are great contenders for outdoor timber cladding design, are typically durability class 2 or 3. Canadian Western Red Cedar is a durability class 2 (as cladding, which is use class 3), for example, while Larch is a durability class 3.

This gives them a lifespan ranging from around 10 to 25 years when untreated – assuming good installation and ventilation, which are essential for timber cladding projects. Certainly not bad for your cladding, but also not the best.

Our most durable hardwoods, on the other hand, often come with a higher initial investment. They do, however, offer exceptional longevity and reduced maintenance demands, with durability class 1 species lasting for 25+ years without regular treatments or finishes. Ekki, Ipe, and Cumaru, for instance, are all durability class 1.

Working Out ROIs

Let’s see how this works in action, starting with softwood cladding (note: these figures are estimates and do not reflect actual costs):

  • Upfront cost: £45/m²
  • Expected lifespan: ~25 years
  • Maintenance: Re-coating every 3–5 years at approximately £10/m² per treatment
  • Estimated maintenance over 25 years: ~6 treatments = £60/m²

Total 25-year cost: Upfront £45 + Maintenance £60 = £105/m²

Annual cost: £105 ÷ 25 years = £4.20/m² per year

Now let’s take a look at hardwood cladding:

  • Upfront cost: £95/m²
  • Expected lifespan: ~50 years
  • Maintenance: Light cleaning and optional oiling every 5–7 years at ~£6/m²
  • Estimated maintenance over 50 years: ~8 treatments → £48/m²

Total 50-year cost:
Upfront £95 + Maintenance £48 = £143/m²
Annual cost: £143 ÷ 50 years = £2.86/m² per year

While this is not exact, and costs/maintenance are likely to differ depending on species and use, the above is a good example of how ROI is often very different from your initial upfront cost.

Find Hardwood and Softwood Timber Cladding

When comparing ROIs of hardwoods and softwoods, what really matters is the species you choose. A durable timber, such as Cedar, Oak or Ekki, is going to withstand a lot more wear and tear than untreated Pine, for instance. Don’t forget no ROI is worth buying timber from illegal or unsustainable forests, so make sure you see the FSC or PEFC code on the invoice.

Frequently asked questions

Do you supply timber for domestic uses?

Yes, we supply timber for domestic applications as well as commercial and public constructions. From garden decking to shed cladding, we will be happy to supply smaller deliveries for home use.

Is your timber FSC-certified?

Yes, all timber we supply is FSC or PEFC certified and sourced from independently verified responsibly managed forests. If we can’t find your request in FSC/PEFC certified timber we’ll suggest an alternative that is certified or clearly note that the offer is minimum EUTR.

Where does EcoChoice deliver to?

EcoChoice delivers to construction sites, warehouses and homes across the UK, as long as there’s access and unloading for our trucks.

What are the best timber species for exterior use?

There are many different timber species suitable for exterior use and which is the best for your project depends on your requirements. In general, though, we recommend EkkiGreenheartOpepe and Oak for heavier civil/marine uses. For intermediary external use such as decking, where the timber needs to be both strong and durable but not on the same level as civil engineering (bridgespiling, etc) we usually supply CumaruIpe, Jatoba, and Balau. And for the lighter exterior use where the timber is non-structural such as cladding, we deliver CedarLarchThermowood and others.

Which timber is the most durable?

Durability Class 1 timbers are the most durable. This of course depends on the use (hazard) class they’ll be in service for. For direct ground and water contact such as sleepers, fenders, marine piling, etc, Ekki and Greenheart are known to be the most durable timbers available. For decking and cladding where there’s no direct ground contact (use class 3) there’s a much wider range of timbers such Larch, Cedar, Thermo modified Pine or Ash and others.

What’s the best timber for internal cladding?

Internal cladding, where your timber is not in ground and not exposed to the elements can be classed as either use-class 1 or 2 – in which case most timbers will meet this durability criteria. That is not to say they’ll be the best, since internal environments have lower humidity (moisture) levels than outside. So in these cases, it’s best to go for a kiln-dried timber cladding board as these are more stable and delivered already in lower MC (moisture content) than the usual fresh sawn timbers sent to external applications. A word of caution – as timber reacts to variations in moisture, it’s best to avoid cladding any areas inside your bathroom.

How can I make decking less slippery?

The first thing is to ensure your deck boards are kept clean from leaves and other debris which will, over time, cover the surface and make it more slippery. Grooved boards can be used to improve grip if installed and used perpendicular to traffic, so especially useful in narrow passages and footbridges. Lastly, you can add our Grip-Choice strips: these are a mix of epoxy with aggregates that add gripping ridges to your deck area. Gripchoice is an easy way to make decking less slippery and safer, especially over large areas or where there’s high traffic. We can pre-install Grip-Choice strips for your decking before delivery or ship the strips separately to add to your existing deck’s grooves as a retro-fit solution.

What wood machining services do you offer?

We can offer planing, sawing, drilling and profiling of rough-sawn wood to any profile you require: from handrails to large port fenders.

Can you supply pre-drilled timber?

Yes, we will be happy to provide pre-drilled timber which is tailored to your needs for quick installation, thus saving you valuable time on site.

What cladding profiles do you supply?

We provide a wide range of cladding profiles, including tongue and groove, featheredge and shiplap. You can check the standard profiles here – but we can also match or custom make profiles to suit your specific needs.

Does timber change colour?

Yes, timber is well-known for changing colour over time. Some species can darken quickly right after installation, and like most untreated wood will eventually weather to a beautiful silver-grey. Interior timber is less likely to change colour (depending on conditions), and timber can be stained, painted or treated with UV-resistant oils to reduce colour change.

Do I need to treat exterior timber?

Some timbers such as Oak and Ekki, can withstand the strains of exterior use without any treatment. However, to extend the lifespan and maintain the aesthetic of your wood, we do recommend treating your timber with stains and oils. Pre-treated timber, such as ThermoWood and OrganoWood, are low-maintenance options which are more durable, but can have their life service extended by applying a clean and stain maintenance schedule.

Do I need to treat interior timber?

Depends on what area the timber is being used. For floor joists and timber rafters, it is common to see timber treated, or least very well kiln-dried. Other uses such as flooring may benefit from varnishing while internal timber cladding for decorative purposes shouldn’t require any treatment other than if you want to change its colour with different types of stains or oils.

Where are you based?

We’re based in Cambridge, UK, and coordinate multiple sawmills all over the world to manufacture your order. We then organise delivery with a range of hauliers so that your orders gets to your site on time.

What are the usual decking sizes?

Timber decking is usually 21x140mm or similar. For heavier applications where there’s more load and traffic, we deliver 35 or 45mm thick boards (such as Hastings Pier). Narrower boards are also possible: 95-90mm is a standard width – but we can manufacture whatever size you require.

What are the usual cladding sizes?

Typical cladding section sizes are 18×95 and 18x145mm although we can always custom make a section to suit your project’s design requirements. That includes waney edge boards in Oak or Chestnut as well as extra wide 195mm boards.
