The growth comes after the firm secured over £70,000 in new funding, allowing for investment into increasing warehouse space and new cutting-edge technology.
The Company, which employs 67 people, registered 15% year-on-year growth in turnover in 2015/16 and is now on track for a record year in 2016/17.
Crystal Galleries has invested £40,000 in expanding its warehouse from 15,000 to 23,000 sq. ft. and £27,000 on new machinery.
The expansion has been backed by £67,000 in funding from the Tees Valley Capital Grant, which was secured with support from North East chartered accountant Anderson Barrowcliff.
Anderson Barrowcliff also provided access to research and development tax rebates, extra banking facilities and debt funding from UK Steel Enterprise.
Finance director Joanne Lowes, whose father George Lowes founded the business in 1982, said: "The financial support we've received will facilitate our growth in the coming years.
“We've increased our product range and can now offer a much wider range of options to our customers, including sub-surface engraving and full colour photo printing on glass.
“We've also been able to reduce our lead time and increase our stock ahead of a busy 2017, in which we'll be attending a number of major exhibitions.”
James Dale, partner at Anderson Barrowcliff, said: "Crystal Galleries has worked with us for over three years and we've witnessed a lot of change in that time as its growth has continued.
“We are delighted to have provided the expertise and strategic services needed to put the infrastructure in place for future expansion."
