Torrents of water flooded the shopping areas of Camden Passage, Charlton Place, Devonia Road and Colebrooke Row.
Asian art dealer Kevin Page, who has been trading from his gallery since 1968, was forced to clear out his shop and is currently putting his stock in storage.
The Twitter account for Camden Passage said the clear up was continuing after the “devastation left from the flooding”.

Dozens of residents were evacuated from their homes near Angel on Monday and the water was at a depth of two metres in the basements of some properties.
Councillor Richard Watts, leader of Islington Council, said: “This was a large water main pipe and the flooding has caused considerable damage and distress to residents and businesses.”
Thames Water’s loss adjustors are in discussion with residents and businesses affected by the flooding.
