What multi-tenant building electrical involves

Commercial electrical work gets judged on two things: does it pass, and did it delay the trade behind you. The work starts with finding out what is actually there. With multi-tenant building electrical, 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 home sale is often when this surfaces. An inspector flags aluminum branch wiring, a fuse box or a panel with doubled-up breakers, and suddenly there is a deadline. We can tell you which items are urgent and which are only noted.

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.

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

A photo of a panel tells us the brand and not much else. It does not show a loose lug, a scorched bus bar or aluminum on the branch circuits. That is why we come out and look before we put a number on anything, large job or small.

We quote from what we have actually seen on site. You get it in writing with each item spelled out, and the final bill lines up with it.

The inspection is the point

An inspection is an independent check that what went behind the drywall matches what was supposed to. Work that passes has been verified by somebody with no stake in the invoice.

That is also why we would rather you hire a licensed contractor than the cheapest number you can find. Unpermitted electrical work is a problem you inherit, and it usually surfaces at the worst moment.

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.

When to stop and call

When something electrical smells hot or looks burnt, the safest thing you can do is stop using it and call. Do not open the panel to investigate. Tell us what you saw and we will tell you how urgent it is.

Stop and call when a fuse keeps blowing and the fix has become a bigger fuse. That swap lets the wire carry more current than it was ever sized for, and the wire becomes the weakest point in the circuit instead of the fuse.
