An episode of Storage Hunters set in Preston will air on June 16.
Treasures found in a Fishwick storage area will be revealed by stars Jesse McClure and Sean Kelly.
The episode was filmed in December at Army Ants Removal site.
Anthony Walmsley, of Army Ants, said: “We were one of only 10 storage businesses in the country to be contacted to take part, I think because we’ve got a massive Twitter following.
“We had to contact our 600 storage customers asking them not to come in for two days while filming was taking place, and then we locked the gates and about 40 members of the TV crew moved in.
“I think it’s really great for Preston to have big TV stars like Sean and Jesse in the city, and for us to feature on such a popular show.
“It’ll definitely be good for business and it’s exciting for local residents too. People always say nothing interesting happens here.”
The show sees bargain hunting participants bid for items that have been abandoned but they are only allowed to view the lots from a distance.
The episode will be shown on Dave.
