A property in Newcastleton was targeted overnight, with £2,600 worth of tools stolen.
A series of outbuildings in the grounds of the Steele Road home were broken into between 9pm yesterday and 7.15am today.
Two structures were entered and several power tools were stolen from inside.
A Nissan Nivaro car outside the property was also broken into and more tools were taken from within.
In addition, a caravan was also accessed but nothing was stolen.
PC Ian Robertson said: “These tools are worth a lot of money and the owner is keen to have them returned.
“Anyone who remembers seeing anything suspicious in the area between Monday night and Tuesday morning is asked to contact police immediately.
“Similarly, anyone with information that can help us trace those responsible is also asked to get in touch.”
Those with information can contact Police Scotland on 101 or Crimestoppers on 0800 555 111.
