Give or take a tiny bit.

A liter of water weighs 1 kg. When frozen, it's weight will
still be 1 kg. However, water expands on solidification and
the density of ice is .917 kg/l. That means 1 kg of ice is
1.0905 liters.

Thus, this soon to be demolished house with it's 100,000
gallons of water has 109,050+ gallons of ice has had its
foundation pushed out by the freezing of water and will
have its fundation sucked back in by the thaw.
