Pressure Treated Timber is wood that has been submerged in a preservative solution. At MCD Garden Sheds, we use Pressure Treated Wood to provide our customers with a 10 year anti mould and anti rot guarantee.

As a carpentry company, our wood is an essential material. It is lightweight, versatile, flexible material that is easily worked with carpentry tools. It lasts even longer when it’s fully pressure treated.

Wood is less expensive than material such as steel, but it is prone to rot and decay. How do you combat this? The only sure-fire way to protect wood from rot and decay is through ensuring it is treated properly. At MCD Home & Garden our wood is fully pressure treated. 

What does “Fully Pressure Treated” mean?

Pressure Treated Timber is wood that has been submerged in a preservative solution within a pressure chamber. The pressure inside the chamber forces the preservatives to be absorbed. This in turn will bind with the fibers inside the wood. This provides effective protection from rot and decay. The most common preservative solution used in pressure treating is ‘Alkaline Copper Quat’ (also known as ACQ). This solution is used as it is poisonous to the bacteria, insects and fungi, which cause decay and rot. Fully pressure treating timber provides more robust protection than topical treatments. The pressure treatment will protect throughout all the timber as opposed just providing a top layer of protection. 


10 – Year Anti-Rot Guarantee

Through the absorption and binding of the preservatives to the wood fibers. The timber is protected from rot for up to 10 years. This is why all MCD Garden Sheds are made with this timber.

Does this wood matter when buying?

By buying a shed that has not gone through this process, you could expect to see rot two years after construction. The untreated timber is exposed to moisture, insects and contact with the ground. All of these factors accelerate the rate at which rot occurs. Partially treated or coated timber can last up to five years. However the addition of the pressure in the process will protected your shed from rot and mould for 10 years plus.
