I'd hire the Christian to work on the house. In fact, the builder I use regularly is Christian, though not a creationist or an outspoken anti-atheist, and pro-choice to boot. He's talkative. Most construction guys seem to be. But were he a creationist, I'd still hire him.
If there is a god, I want to believe that there is a god. If there is not a god, I want to believe that there is no god.
