Pressure treated or dip treated β what's the real difference? πͺ΅
This one question can save you a lot of money and hassle over the life of your building.
Dip treated timber β timber briefly immersed in treatment. Surface protection only. Will need retreating every 1β2 years to maintain warranty and prevent rot.
Pressure treated timber β treatment forced deep into the timber fibres under pressure. Protection that lasts 10β15 years. Typically carries a longer manufacturer guarantee against rot and wood eating insects.
The upfront price difference is often less than people expect β but the long-term difference in maintenance time and cost is significant.
Our advice? Go pressure treated wherever your budget allows.
