What subpanels involves

When the power goes down in a business, the clock starts on lost revenue. The work starts with finding out what is actually there. With subpanels, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We tell you what we find before we tell you what it costs. If the scope is smaller than you expected, it gets smaller. That happens more often than people assume.

Where this comes up

Build-outs, tenant work, lighting and three-phase power for buildings that cannot go dark. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

A lot of the work in Illinois starts in a house or building that has been added onto more than once. Each addition borrowed power from whatever circuit was closest, and by now nobody knows which breaker feeds what. Sorting that out is part of the job.

How we do it

Licensed and insured on every call. No job is too small to do properly, and no shortcut is worth an inspector’s red tag. We would rather do it once.

What changes with an older building

Buildings in this part of Illinois cover about a century of wiring practice. Knob-and-tube in the oldest, cloth-insulated branch circuits after that, aluminum wiring in a stretch of the sixties and seventies, and modern copper since. Each one fails differently and each one has its own repair path.

We look at what is actually in the walls before quoting, because guessing from the year the house was built is how people end up with a surprise halfway through.

Who actually shows up

You get someone who has been in tough situations and knows what they are looking at. Our crew is licensed, works on everything from homes to government facilities, and does every part of the job in-house.

Before the visit you know who is coming and roughly what time. If something holds us up, we call you. You should never be left watching the driveway.

Code, permits and inspection

Illinois municipalities adopt the National Electrical Code on their own schedule, which means the rules in one village are not always the rules in the next one over. Permit thresholds differ too. Some places want a permit for a circuit, some only for a service change.

We deal with whichever jurisdiction the job sits in. We pull the permit, we schedule the inspection, and we are there when the inspector walks it. You get the paperwork at the end, which matters when you sell the building or when an insurer asks.

Copper, aluminum and what is in your walls

Aluminum branch wiring went into a lot of houses in the late sixties and early seventies. It is not automatically dangerous, but it expands and contracts more than copper, which loosens terminations over time, and it needs devices and connectors rated for it.

The repair is usually not a full rewire. Proper connectors at every termination, done thoroughly, solves most of it. Anybody quoting you a whole-house rewire on sight has not looked.

What to do before we arrive

A warm faceplate or a buzzing switch means stop using it. Turn that circuit off at the panel, tape over the switch or outlet so nobody in the house uses it out of habit, and leave the device in place for us to look at.

Keep track of patterns. Does it happen in the morning, in the rain, when the microwave runs? Patterns point us straight at the fault.
