It probably would be cheaper to bring back it done while it's under construction, but you really involve to make sure that your subterranean vault is completely and totally watertight, or you'll have big problems down the road.

It's cheaper to get things done contained by the initial building
phase, as compared to doing it later.

Cheaper still to do it yourself.
Which One is Best?
Answers:    If your house is under construction, right in a minute, it is cheaper to get a quote from the present contractor.

A subsidiary contractor later will cost more, because he isn't making any money on the rest of the house. The present contractor will bestow you a much better price, due to the fact he is already here working, and has the manpower and resources on paw.
