What we do

Technology you use every day. Wiring you never see.

Speakers on the deck. A TV hung from the ceiling. Ethernet in every room. The receiver and cable box tucked in a cabinet, run by one remote.

That is a typical CSI job. We design it, wire it, install it and stick around to service it.

Common questions

What areas do you cover?

Northern Virginia, Washington, DC and Maryland. We are based in Alexandria, VA.

Do you work on homes and businesses?

Both. We install and service systems for residential, business and government related clients.

How long have you been in business?

Since 1980.

Can you wire a house that is already finished?

Yes. We fish cable through existing walls and work with a drywall contractor we have used for years, so the patches disappear.

Do you work with my builder or general contractor?

All the time. We coordinate with your GC so wiring goes in before the walls close.

Do you only do high end systems?

No. We install high end and mid level systems. We will size the system to the room and the budget.

Do you service systems after install?

Yes. We service what we install and can look at existing systems too.

How does it start?

A call, then a walk through at your home or office. We look at the space, listen to what you want and give you options. No hard sell.
