We’re a specialist plastic building supplies merchant for both trade and DIY customers. We have been trading for over 20 years now. In that time we’ve built a reputation for affordable but high quality products that improve the inside and outside of people’s homes.

Our focus as a plastic building supplies merchant is on supplying low maintenance products that look great and stand up to the rigors of everyday use.

We sell our plastic building supplies through our stores in Cardiff,Gloucester, and Swansea and online. We’re delivering nationwide from Monday to Saturday. No matter where you are in the UK or Ireland we’ve got you covered.
