Firefighters were called to deal with 47 flooding incidents across Teesside as heavy rain blocked drains and deluged homes.
All the incidents were recorded between 9pm and just before midnight on Monday.
Worst hit was the Stockton area with firefighters called to Eaglescliffe, Egglescliffe, Hardwick, Hartburn, Bishopsgarth and Fairfield.
Homes in the Owton Manor area of Hartlepool were also flooded after the sewers overflowed.
Elsewhere, the Environment Agency placed a flood warning on Lustrum Beck in Oxbridge, Stockton.
The 12-mile long beck has burst its banks many times over the years and there were concerns it may do so again.
A spokesman for the Environment Agency said: "The Teesside area had about 60mm of rain in 36 hours. We did put the beck on flood watch as a precaution, but there was also a lot of surface flooding water as drains were unable to cope with the heavy rain."
