How they have been treated will impact a number of things from the finish of the shed, the required maintenance, and the shed’s lifespan. 

There are two different types of treatment for garden sheds: dip treatment and pressure treatment. This article explores the differences between the two and whether you should be opting for a pressure treated or dip treated shed.

Dip-Treated Wooden Sheds

Dip treated garden sheds are typically the cheaper alternative out of the two. It would, therefore, be a suitable option if you’re looking for a shed on a budget and one which doesn’t necessarily need to stand the test of time. 

However, there is a reason dip treated sheds are typically cheaper. As the name would suggest, dip treated sheds are essentially dipped into a ‘bath’ of wood treatment to cover the exterior of your garden shed. This does mean, however, the wood treatment will not have time to penetrate deep into the timber. As such, it is unlikely your garden shed will last as long as a shed which has been pressure treated unless you carry out annual maintenance to ensure it remains protected. We recommend staining your garden shed every year.

Pressure Treated Sheds

Pressure-treated sheds are far more superior and therefore more expensive than their dip-treated counterpart. Pressure-treated sheds have wood preservative injected into the timber to ensure all the wood is permeated as opposed to just the exterior of the shed. Because the treatment is much more advanced and effective than dip treating, this will be the difference between treating your shed annually (dip treatment) or not needing to treat your shed at all (pressure treatment).

During the pressure treatment process, the timber is loaded into a treatment vessel where the initial vacuum is applied to draw out all the moisture and air. Once this is complete, the cylinder is flooded with wood preservative and hydraulic pressure is applied to force the preservative to penetrate deep into the structure of the timber. A second vacuum is applied to extract excess preservative solution. The timber is then vented and left to dry.

With a pressure treated shed you can have peace of mind knowing your garden shed is protected from the adverse effects of weathering such as rot and decay, as well as insect and fungal attack.

Although not required, we still recommend maintaining your garden shed either by applying a wood stain every other year and/or adding a water repellent to protect it from water.

What is the right shed for you?

Although the benefits of a pressure treated shed far outweighs the benefits of a dip treated shed, the price will be an important factor in your decision. 

If you’re looking for a garden shed on a budget, we would recommend opting for a dip treated wooden shed. However, if you’re looking for a garden room that is going to stand the test of time and needs little to no maintenance then a pressure treated garden shed would be favourable.
