James Latham has posted a 33% growth in operating profits to £4.46m for the six months to September.
The company, whose pre-tax profits were up to £4.59m (2009: £3.13m), also recorded a 13.4% rise in turnover.
“Group revenue has continued improving on a month-on-month basis and this is the result of both higher prices and increased volumes,” said chairman Peter Latham.
“Prices have continued to rise but at a much-reduced date in the period July to September.”
The sales growth was achieved in timber and panel product divisions, with the group’s Scottish depot making a positive contribution.
Mr Latham said October and November accounts show continuing strong revenue but margins remained under pressure.
“Future levels of activity in many sectors are unclear and this makes it difficult to predict future trading patterns,” he said.
“The level of bad debt has been below our predictions and below the levels seen last year, but there are signs that companies will come under pressure again this winter.”
