Northumberland Estates, which owns part of the land in Newburn, Newcastle where a block of flats are near to collapse, have apologised to residents.
A spokesman said:
"Unfortunately, the exceptional weather conditions experienced this summer, which have seen the North East subjected to two of the most exceptional storms on record, have caused many problems for the team.
"There is little we can do in the face of such very extreme weather conditions until the culvert can be cleared. We hope to achieve this in the next three to four months.
"Of course, this is no consolation to the residents. Northumberland Estates representatives have been on site throughout and we remain committed to doing everything we can to support them.
"We are working hard to ensure the best possible outcome for them in the short, medium and long term, and will continue to work with them ... to alleviate some of their more immediate concerns where possible."We are also working closely with the police and other services at the present time, and are pleased to announce that the majority of residents affected are now back in their homes."
