Why choose pressure treated timber?

Pressure treated timber is timber that has been infused with preservatives under high pressure. This process helps the wood resist moisture and pests, giving you peace of mind for years. It’s the smart choice for outdoor structures like decking, sheds, or fencing.

Can you paint treated timber?

Yes, you can. Many customers ask, “can you paint treated timber?” The answer is simple – once the wood is fully dry, you can paint or stain it to suit your style. This adds another layer of protection while improving the look of your project.
