Issue with spacing

Hi all, if anyone could help me with this issue it would be greatly appreciated.
The spacing of the “search” and “location” box is too small and I was wondering how I could fix it. Is it a coding type issue, or should I re-install the plug in??
I couldn’t attach a photo, but here is the link to the issue http://www.canadianbic.ca/find-a-church/
