I think the expression you mean is: Set our house in order.
To set one's house in order means to organize one's affairs (financial, legal, etc.). It is also often used in the context of 'don't point out the faults of others until you have taken a good look at your own behavior'.
Here is an example of the expression from a recent news story:
LUCKNOW: Maharashtra Chief Minister Vilasrao Deshmukh on Friday said that instead of commenting on the Congress, the Bharatiya Janata Party should first set its house in order.
