Windshield still leaking

I just had my the windshield taken out and resealed today while I was at work. I was all sorts of excited to finally not have to worry about finding puddles in my car. Anyways, I get home and do the garden hose check and it leaks worse than before! Its kind of upsetting. I took out the glass and cleaned all the surfaces a couple days ago thinking this was my problem. Anybody have any tips on getting it to seal?
