South Wales Police has been working with Trading Standards to tackle rogue traders in the Vale of Glamorgan.
It follows a warning last month from the Police about Rogue Traders operating in the Vale of Glamorgan, targeting elderly residents in Sully, Barry and Llantwit Major.
Traders had been offering basic gardening and house maintenance for inflated prices.
One woman was coned into handing over money to two men who claimed to be checking guttering on behalf of a neighbour.
Another man in his 80s was charged £1,200 for having his drive power washed.
In these instances, little to no work had been carried out.
Officers have since teamed up with Trading Standards to carry out pro-active and targeted patrols across the county.
They have been checking on individuals and businesses seen working on properties.
During these checks paperwork was inspected and residents spoken to about how the work was agreed.
Sergeant Natalie Harris based in the Community Safety Partnership at Barry Police Station said: “We hope this operation sends a clear message to rogue traders that we will not tolerate vulnerable people being targeted by such scams and doorstep crime.
“Residents can feel reassured that we are committed to driving such traders out of the Vale.
“Please be vigilant to these kinds of scams, look out for elderly or vulnerable neighbours and contact us should you have any concerns.
Rogue Traders often target elderly or vulnerable customers and will use forceful tactics and intimidation to secure work.
Anybody who suspects rogue trading should contact 101 immediately. In an emergency they should dial 999.#keepingTheValesafe
