Cast iron gutters and pipes offer great strength and durability, a proven history of long life, low noise operation and fire resistance. Most old buildings have cast iron rainwater systems that should be maintained and preserved however; these inherent benefits make a cast iron rainwater system an ideal choice for both traditional and modern installations.

Our standard spike or sturt length is 300mm (12″). Other sizes are available upon request.
It is possible for us to supply towel warmers with an electric heating element in them. The Electrad system is a unique system available to us, that enables independent heating of towel rails and radiators via the properties electrical system.
Yes. All our mild steel brackets are supplied in either silver or black zinc plate. This coating protects the metal however, both will need painting prior to installation.
We have chosen to use zinc plating for two reasons; firstly that it is a more environmentally friendly than galvanising and secondly that it does not block up the threaded part of the rise and fall cups in the way that galvanising does.
We manufacture a wide variety of brackets for many different cast iron gutter and pipe profiles. More common types are the rise and fall, top fix and side fix rafter and the holderbat or pipe clip.
We can also offer traditional drive brackets, repair brackets and fascia brackets in both steel and cast iron.
It is always advisable to replace like with like because quite often the brackets form and important part of the buildings architecture. Occasionally buildings have special decorative brackets and our UK manufacturing allows us to produce small quantities of bespoke brackets when required.
We are able to place dates and initials and insignia onto most of our flat faced rainwater hopper heads.
Yes. Cast iron is the material required by most conservation officers and listed building consents for the replacement or replication of traditional rainwater goods. Our hopper heads are produced in solid cast iron and we can assist with specification notes or material statements for planning purposes if required.
We do offer a range of Ogee patterned gutters in both straight and radius profiles. The straight profiles are much more common and as such cost less.
Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.
The Calnethorpe is designed for formal classical and Georgian elevations where scale and material authenticity matter — large townhouses, country houses, manor houses, and institutional buildings. It is also widely specified for new-build heritage projects where cast iron rainwater goods are required to conservation standard.
