Twelve crews went to the scene of the fire on Tuesday afternoon at the Manor Way Business Park in Swanscombe.
A 200m exclusion zone was put in place because of fears acetylene cylinders were inside the building, later reduced to 50m when only propane was found.
By Wednesday morning, the fire was extinguished and one crew remained searching the debris for hotspots.
Much of the warehouse was destroyed by the blaze which began just after 1730 GMT.
Kent Fire and Rescue Service also sent 12 crews to tackle a house fire near Dover on the same night.
A three-storey detached house in Church Hill, Eythorne, was badly damaged in the blaze.
The fire service said no-one was inside the property as it was used as a holiday home.
