Simon Brocklehurst spent 12 hours plastering the 6m (19ft) x 7m (22ft) flag on his four-bedroom end-of-terraced home.
The 41-year-old welder's patriotic gesture came after neighbours tore down a St George's cross which he had been flying in his front garden.
Simon admits his response has seen him become "public enemy number one" but insists he's mainly received praise for his display.
However, some locals have said they worry the "garish" red, white and blue paint-job would now devalue their own homes if they wanted to sell up.
