I had many concerns including their professionalism. They were to set up in home theater, many extra charges, childish behavior. When they told me they usually conceal cables and electrical wiring in the walls I asked if they were licensed and needed a permit? The response was we do this all the time.

Be careful you as the homeowner become responsible for that work, in the event a fire or someone gets hurt you could be liable and your Homeowners voided. BE CAREFUL. unlicensed work is illegal and unsafe. If they did it correctly why hide from an Inspector. Best Buy to fall right behind Circuit City because of the GEEK Squad.
