Aluminium Gutters — Frequently Asked Questions

Aluminium downpipes are lightweight, corrosion-resistant, and recyclable, with a 50-year lifespan. They handle high flow rates and come in round or square profiles for aesthetic flexibility.

We recommend that all pipe joints are sealed with low modulus silicone sealant. Sealing the joints prevents water over spilling at tight bends where water turbulence could build up, locks the pipes in position preventing rattles and improves flow performance as air is not being sucked in through open joints. Our various aluminium downpipe systems can be viewed here.

Common diameters include 63mm and 76mm, and 72x72mm in square. Lengths are supplied in 3 metres but are site cut to building height.

Brackets should be spaced 1-1.5 metres apart vertically, with additional support at bends or offsets for stability.

Yes, but use compatible fixings to avoid corrosion. They're best paired with aluminium gutters for uniform expansion and aesthetics.

Connect to gutters with offsets if needed, secure with brackets, and ensure vertical alignment. Seal all joints and direct flow to drains.

No, the powder-coated finish is durable and fade-resistant. Repainting is optional after decades for refresh.
