Site info and socials positioning on mobile

I have a logo that spans most of the top header and with your help I managed to get the logo positioning perfect when viewed on a mobile device… my issue now is that when viewing on mobile the phone number and social icons either appear off the page (to the right) or not at all and there is also quite a bit of white space before the menu button.
Have a look here: http://www.buyselllondon.ca
Any help I can get to position the socials and phone number properly would be great.

Thanks!
