The independent water treatment specialist boasts a string of blue-chip clients across the UK and is continuing to grow on Teesside.
Managing director Bill Abbott was delighted with the firm’s financial results for year ending 31 December.
He said: “We are delighted with the figures for the year just ended.
“Reaching the £1m mark is a milestone, we have been close a few times but this is the first time we have achieved that goal.
“We had an excellent performance over 2015, building up our client list, bringing in new staff to cope with the increase in workload and generally widening our horizons in terms of the work we carry out.”
The financial state of the business is poised for a further boost after a contract worth in excess of £100,000 was secured with an inner-city London council to carry out chemical cleaning and maintenance work on the heating systems in 24 schools.
He added: “We are well positioned going into 2016, and we want to build on the success of 2015 over the next 12 months.
“The nature of our work in the leisure sector means from March to October in the holiday season our workload increases dramatically.
“However we have a clear vision and Hydrochem is targeting a further 30% growth on sales, with a view to further recruitment of enginners later in the year.”
