Founded in 1888, G Johns & Sons Ltd is a family-owned business with over 125 years of history and expertise. Originally established as builders and contractors in Islington, North London, we have evolved into specialists in architectural ironmongery, serving both trade and public customers with high-quality fittings and unrivalled customer service.

In 1996, under the name The Brassware Company, we opened our first showroom in Winchmore Hill, North London. Since then, we’ve expanded and in 2012 opened a larger showroom, praised for offering the best selection of ironmongery in London and the South-East. In 2015, we returned to our roots by reinstating our original trading name, G Johns & Sons Ltd.

Our team is made up of experienced professionals, many of whom have backgrounds in construction and associated trades. We are proud members of the Guild of Architectural Ironmongers, with fully qualified staff who stay up-to-date with the latest fire and building regulations. This enables us to provide expert guidance, from creating full ironmongery schedules to assisting with the selection and installation process.

We supply ironmongery for a wide range of projects, including residential properties, large developments, listed buildings, and commercial spaces like offices, schools, and hospitals. Whether it's a single item or thousands, we are equipped to meet the needs of architects, builders, designers, homeowners, and more.

At G Johns & Sons Ltd, we are committed to offering a comprehensive service. From helping you navigate regulations and compiling schedules to providing refurbishment and restoration services, we have the expertise to bring your project to life.

If you can’t find what you’re looking for or need advice, our team is always ready to assist. We stock thousands of products from over 100 suppliers, and if needed, we can even replicate original pieces. Whatever your project, we are here to help.
