Reasons To Use Treated Timber In Your Garden Construction

Last Updated on June 12, 2023 by Real Men Sow

Using untreated timber for your DIY tasks or construction work in your garden could cause damage to your external fixtures, such as ruining your decking, fencing or outer walls. 

Treated timber is a stronger, more durable alternative which can endure harsh weather conditions and is incredibly reliable for use in your garden.  

What Is Treated Timber?

Treated timber is ideal for outdoor use – it involves any timber which has been altered with preservatives to ensure full protection and longevity when it is used for external purposes. 

Treated timber can be used for a number of applications and will be protected from structural degradation, flames, decay fungi and termites. 

Wood that has been treated correctly can also help to reduce the number of trees required to perform the same functions, as treated timber is dependable and can last for many years. 

Life span

Treated timber is significantly more reliable than untreated timber. The life span is greater due to the preservatives used during the production process

Wood that isn’t protected can begin to rot within a year or two, depending on the environment it is being used in. Treated timber can last for at least 15 years or more if it is well-maintained.


A great advantage of treated timber is that it is incredibly durable and can withstand wear and tear. This means you can rely on the material to build your garden fixtures, from fencing to decking, without having to worry about degradation or replacements for years to come.


You can rest assured that your treated timber will be protected from a wide range of wood-boring insects and fungi. Insect attacks can create a series of holes in your wood, reducing the overall strength of the timber. 

Treated timber ensures the material remains free from moisture, which helps to resist both fungal growth and burrowing insects. 


Treated timber is produced with great strength so it can be used for outdoor projects. As it is often found in timber framing, ceiling, floor and deck joists as well as the construction of garden buildings, the material needs to be strong and long-lasting. 


This material is incredibly versatile as it can be used for a number of applications and other varied aspects of building work. It is available in a wide range of sizes depending on the task at hand, making it ideal for both small and large projects.

Hello, I’m Pete and I’m currently based in the west of Scotland, in a small place called Rosneath, where I’m exploring my garden adventures. I personally started gardening around 6 years ago and initially, I started out by growing my favorite fruits and berries, such as strawberries, Raspberries & Gooseberries. Since then I’ve added a lot of vegetables and working closely with my neighbor, it’s been a lot of fun.
