What electrical service upgrades involves

A building owner wants the same answer every time. Is it safe, and when is it done. The work starts with finding out what is actually there. With electrical service upgrades, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

We explain the job in plain terms before anything starts: what we are changing, why, and how long the power will be off. If a smaller fix does the job, that is the fix you get.

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.

Commercial spaces change hands and change uses. A storefront becomes an auto shop, an office becomes a gym, and the wiring stays what the first tenant needed. When the new equipment shows up, the old circuits are usually the first thing that has to change.

How we do it

We work like it is our own house. Drop cloths go down, the power stays off only as long as it has to, and the work is finished to code with the permit closed out where the village requires one.

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

Same people, every job. The licensed electricians who handle commercial and municipal work also take the small residential calls, and every part of the work stays with us, including the tedious parts.

You will know who is coming and roughly when. If traffic or an earlier job pushes that back, we call to say so. It is a small thing that a lot of this trade still gets wrong.

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.

Grounding and bonding

Grounding is the part nobody sees and the part that decides whether a fault clears safely. The ground path has to be continuous and low-impedance from every device back to the service, and the neutral and ground can only be bonded together in one place.

A neutral bonded to ground in a subpanel is one of the most common defects we find. It works right up until it does not, and then it puts current on metal that people touch.

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.
