Very slow draining bathroom sink

We had a bathroom reconstructed and a pedestal sink installed where an old sink had been. This sink is draining very, very slow. I used a hand snake, went right down the drain, and five feet into the system. The auger will go no further even if I put careful pressure on it and rotate it. This is the only draining problem we have in the house. Could it be that construction debris got into the drain line when the work was done? Would this be cleared by a more powerful snake or would I do real damage? Could a snake be going into a wrong pipe and giving misleading feedback? What should I do?

The snake may have gone UP a vent pipe instead of down the drain. And there may be a partially clogged vent pipe causing the problem.
Go up on the roof and snake the vent pipe above the bathroom, and flush it with a water hose sprayer to see if that helps.
Did you remove the trap to see if there is sludge (soap, makeup, hair, etc.) build-up that a snake will push right through without removing?
If snaking it doesn't help, you might try a good enzyme-based sludge-eater like DrainCare. Just follow the directions on the jug. Works for me.
Good Luck!
