Cherry Orchard Road and part of Lower Addiscombe Road is closed for emergency works after a water main burst flooding the basements of two homes.
Thames Water got permission from Croydon Council to start emergency works on the site about 2pm today.
They have been replacing the Victorian water mains along Cherry Orchard Road for the past few weeks.
Ali Badel. 51, the owner of Euro Dry Cleaners on Cherry Orchard Road says his business is being affected by the road works and that neither he nor any of the other businesses along the road were informed about the works.
"Nobody can come into the shop because the road is closed and they cannot drive their cars down here.
"We were not given any information about this; if we had been then at least we could be prepared. It is fairly amazing. This is the second time my business has been disrupted by Thames Water works."
Councillor Andrew Price said:
"Given that these works to Victorian mains are over 100 years overdue, the patience of the people of Addiscombe is being severely stretched by this further disruption".
Thames Water apologised to customers and road users for the disruption.
A spokesman said:
"We are working through until the road works have been completed, we are working as quickly as we can and hopefully they will be completed as soon as possible. This is an emergency repair and we had to get on the site as soon as possible."
