You did all that work to get people to your website, and yet you're inviting them to leave. That's what you're doing when you place social media icons in a prominent location of your website, like in the header. Bury the icons in the footer instead.
If people are on your website, you want them to stay, learn and perhaps inquire about your services, not check out company picnic photos and bowling outings on Facebook. Social media should send people to your website, not vice versa.
