Under the trading name of The Brassware Company, we moved into supplying architectural ironmongery after opening our original showroom back in 1996 in Winchmore Hill, North London where we remain today selling architectural ironmongery to the trade and public.

As of May 2012 we've expanded and opened up a new larger showroom, which has being widely described by our customers, suppliers and manufacturers as the best showroom with the widest selection of ironmongery in London and the south-east.

As of January 2015 we decided to drop our trading name and return to using our limited company name of G Johns & Sons Ltd.

All of our staff have experience in the building and construction industry and associated trades. We are also full members of the Guild of Architectural Ironmongers with staff members that are full qualified registered architectural ironmongers. This means we keep up with the latest fire and building standards, making us qualified to complete full ironmongery schedules for residential, commercial and public buildings, therefore we are extremely well qualified to support and advise our customers.

We boast a wealth of experience in the business, supplying both the public and trade with the highest quality of fittings, backed by first class expertise and knowledge. We believe our levels of customer care are second to none. Equally, our sympathetic approach to customers taking on new challenges helps us to guide them right through starting with scheduling from architects drawings and quotations to the selection process and through to installation. As well as the many standards we have come to know, the only limitation is your own imagination and quantity is no issue, whether it be a single piece or thousands, we can provide exactly what you need.
