Thames Water said the flooding was caused by a burst water main on Coombe Road and apologised to customers.
It said the leak was shut off at about 01:30 BST on Friday morning and water had been pumped away.
A Thames Water spokesman said: "Our engineers shut off the leak at 1.30am and our customers' water supply has returned to normal.
"We are now helping the water drain away using pumps and tankers before we begin a clean up."
Local road closures are in place while repairs are carried out.
