What electrical trenching involves

Commercial jobs live or die on coordination, not on wire. The work starts with finding out what is actually there. With electrical trenching, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

A diagnosis comes before a scope. Once we know what is happening and why, we lay out the work, and you decide how much of it you want done now.

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

Every connection gets tightened properly and every wire is sized for the load it carries. Where the village requires a permit, the inspector signs off on it, so the standard is on paper as well as in the wall.

Why it usually cannot wait

Electrical problems do not stay the same size. A loose connection heats up, the heat oxidizes the metal, the oxidized metal raises the resistance, and the resistance makes more heat. That loop runs in one direction only and it ends at a scorched box.

If something is tripping, buzzing, warm to the touch or smells like hot plastic, that is the system telling you where the problem is while it is still cheap to fix.

How we quote it

When there is more than one way to do the job, the quote says so. A subpanel or a new service, repair or replace: you see both options priced, with our honest read on which one your building actually needs.

What you get is written, itemized and tied to a scope. If we open something up and the scope genuinely changes, we stop and tell you before we keep going. No surprises at the end.

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

Outdoor problem, like a damaged service mast or a line down near the house? Stay well back from it and keep others back too. Do not try to move anything. That one involves ComEd as well as us, and we will coordinate it.

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