FAQ

What makes cast aluminium different from regular aluminium gutters?

Cast aluminium is produced by pouring molten aluminium into moulds, giving it a thicker, more traditional look similar to cast iron. Extruded aluminium systems are smoother and more modern, while cast aluminium suits period or heritage properties.

Is cast aluminium suitable for listed buildings?

Yes. It’s often approved as a replacement for cast iron on listed and conservation properties because it closely replicates the traditional style while reducing weight and maintenance needs.

How long will cast aluminium gutters last?

Typically over 30 years, depending on conditions and upkeep. They’re highly resistant to corrosion and weathering, especially when powder-coated.

Does cast aluminium need painting?

Most of our systems come with a durable powder-coated finish in heritage colours such as black, white and anthracite. Additional colours are available on request, and no further painting is required once installed.

Are cast aluminium gutters heavy?

They’re much lighter than cast iron yet strong and rigid enough for long-term use. The reduced weight makes installation quicker and easier.

How should cast aluminium gutters be maintained?

Maintenance is straightforward - clear debris twice a year and check for blockages or joint wear. Avoid harsh cleaning agents to preserve the powder-coated surface.
