Cast Iron Downpipes

For a strong and durable rainwater solution for period properties in need of heritage guttering replacement, look no further than Yeoman Rainguard’s Cast Iron downpipes. Many properties built in Britain during the 1700s and onwards retain their original Cast Iron rainwater systems, a testament to the material’s quality.

Manufactured by Hargreaves, the UK’s leading manufacturers of Cast Iron rainwater products, our Cast Iron downpipes provide many years of service if maintained correctly, with lifecycles of up to 90 years if repainted periodically.
