site title positioned differently between pages

My sight title is set up in Decode’s theme customisation. I’ve added drop shadow effect to create cool 3D and rollover effect. http://say-write.com

The strange thing is that the site title keep shifting right about 7 or 8 pixels depending on which page I’m on. The site is in the early stages, and there are only 4 pages, first two ‘home’ and ‘testimonials’ are in one place, and second two ‘services’ and ‘contact’ are in a different position.

I’ve used Chrome’s Developer tools to check all the div sizes and they all seem to be the same widths between all the pages, so I don’t get it. I see the effect in Chrome and IE, but not on mobile Chrome.

Any ideas? It’s a small flaw, but it looks unprofessional to my eye, so I’d like to get to the bottom of it if possible.
