Site looks great! First comment, the menu. I'm not so sure I'm a big fan of that feature you have that turns the menu option you click into a link to the homepage. Its cool, its thoughtful, but at the end of the day, confusing. I found myself on a couple of occassions clicking the first menu option and going to the about page. A static menu is always easiest on the user, but the way you have it is cool too, so if you want to keep it around, by all means. Also keeping with the menu, that arrow at the very end is misleading, I thought there would be more options if I clicked it, instead nothing. I'm guessing you're using it as a space filler, maybe point it downwards instead, but pointing it to the right usually implies more options to be seen. Another thing I just stumbled on, if you click the Peterborough Paint Services logo a few times, the first menu option goes back and forth from homepage to about, even though the content remains the same. Whats that about.
Anyway, enough about that menu. On the index page, the pic of the guy with the moustache has grey dots running across his face from the border you were making! Maybe edit that out. Browsing through the other pages, it looks fine. My last suggestion, a footer. Its the only thing lacking from your site, toss in a Copyright at the bottom, All Rights Reserved, go crazy. It'll make that black portion at the bottom of your site look more appealing. Add in your meta description/keywords tags. Great job all around though.
