Mahjacks of Dedworth, Windsor – which received the Royal Warrant of Appointment as a Tradesman to the Queen after supplying goods to the royal household – is closing down after 50 years of trading.

Family-run Mahjacks opened in Dedworth Road in 1966. It was granted the Royal Warrant after supplying a number of goods, beginning with an order of 6 x 6 inch white tiles, to nearby Windsor Castle.

The business is currently run by sisters Pamela Needham and Jackie Wixon-Jones. The sisters considered downsizing back in 2011, but were unable to find a suitable alternative site. Last week they accepted an offer from developer Patrick Ruddy Homes and the store is now set to close for good in July.

According to local press, the store has seen a huge increase in female customers in recent years, with Jackie Wixon-Jones commenting: “It’s really noticeable how many more women we’re getting in here now. My sister is a small and petite woman and we used to have builders who’d come in and they’d walk past her and go to one of the men.

“But invariably, Pam would end up intervening. She just knows everything about DIY.”

Mrs Wixon-Jones, who is planning to retire once the store closes, also paid tribute to the shop's customers, saying “they are the best customers and we've been really lucky.”

The site currently has planning permission for a 5,000 sq ft shop with room for 13 flats above it.
