FAQS

Will copper or brass rust, go green, or require much maintenance outdoors?

No copper and brass do not rust like iron. Instead, they develop a natural patina over time, deepening in tone to rich browns and eventually, in some environments, a blue-green verdigris. This change is not damage, but rather a protective layer that makes these metals ideal for outdoor use.

If you love the character of ageing metal, there’s very little maintenance involved. But if you'd prefer to keep the original shine, we offer satin lacquered finishes to slow tarnishing, as well as maintenance kits with polish and cloths. Unlacquered copper typically begins to darken within a few weeks depending on climate and exposure.

Whether you want a sculptural, aged look or a polished centrepiece, the finish is up to you.

Can I install this tap myself, or do I need a plumber?

Yes our copper and brass tap are designed to be easy to install at home. For mains-fed or custom plumbing setups, we recommend using a plumber. Every tap comes with all the fixings and clear step-by-step instructions to get you set up quickly.

Can I customise the tap to suit my space, style, or height?

Yes every Proper Copper tap can be tailored to you. We offer a range of customisations, including different tap handle designs, and spout projections.

If you're taller or designing for a specific setup, we can also adjust the overall height or spout length. Looking for something truly unique? We welcome bespoke commissions and can create one-off pieces with your preferred finishes, features, or even engraved detailing.
