Lake Carolina, The Summit, Rice Creek, Longcreek, and everything along Hardscrabble and Clemson Road are about fifteen minutes from my house. I'm out that way most weeks. Bigger houses out here mean the Wi-Fi question comes up a lot, and I bring what I need to test it room by room.
The repair counters at Sandhills will take your computer for a week. I'd rather come to you, fix it at the kitchen table in an hour or two, and show you what I did. If you'd rather not have anyone in the house, most things I can do remotely while you watch on your own screen.
Call (803) 265-8088. If I'm under someone's desk, leave a message and I'll call you back the same day.
$175 remote or $275 at your house, up to two hours. Card when it's done.
Other places I go: Spring Valley and Wildewood, Blythewood, Elgin and Pontiac, Forest Acres and Arcadia Lakes.
