I can't recommend TechSystem more highly. Professional work. Clean. And only a very brief explanation was needed for me before they got to work. Hire them!
Details:
We recently renovated our basement and we used it as a time to run some ethernet through the wall and upstairs to my office. The contractor who did the work left the cables in the walls but the outlets were not installed and the wiring in the basement was a mess.
We hired TechSystem to come in and install outlets and sort out our wiring. We also wanted a few additional rooms wired, and based on the reviews decided to see if they were up to it.
TechSysem did a beautiful job cleaning up the wires, labeling the jacks, installing a patch panel, and adding new jacks where needed. The real magic was when we needed a new jack installed running from the main floor to the basement. They were able to do this by drilling two holes, one from the basement and one from the main floor, measure well enough that they would connect, and do the whole job cleanly without making any additional holes in the walls. Super impressive.
