What college electrical work involves

School electrical work happens in the window between June and August, or it does not happen. The work starts with finding out what is actually there. With college electrical work, that means looking at the existing wiring, the panel capacity and whatever the last person left behind.

Most of the time the job is smaller than the worst case people read about online. We find the actual fault, fix that, and leave the parts of the system that are working alone.

Where this comes up

Summer-window work in classrooms, gyms, kitchens and athletic facilities. Most of these calls come from Des Plaines and the surrounding suburbs, but we take them anywhere in our service area.

Previous work is the wild card. Plenty of Illinois homes and shops have circuits somebody extended on a weekend, splices buried in a wall with no box, and breakers upsized to stop a nuisance trip. We find those first, because they decide what is safe to build on.

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.

What we see go wrong

Most of the bad work we find was not done by an electrician. It was a handyman, a previous owner or somebody who watched a video. Backstabbed outlets, undersized conductors, missing grounds, neutrals and grounds bonded in a subpanel, junctions buried inside a wall with no box.

None of that is visible from the living room. It surfaces during a remodel, a home inspection, or the day a breaker stops holding.

What happens when we are done

The work gets tested, the circuits get labeled properly in the panel, and the site gets cleaned up. Labeled panels matter more than people think, because the next person working on that system is reading your labels to decide what is safe to touch.

Where a permit was pulled you get the closed inspection. Where documentation exists, you get it.

What the permit actually buys you

A permit puts the work on the public record for the address. When the building changes hands, that record is evidence the electrical was done and checked. Without it, a buyer's inspector treats everything they find as suspect.

It also means the work was sized and installed to the code edition in force, not to whatever was normal when the building went up.

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.

The warning signs people ignore

Lights that dim when a large appliance starts. Outlets that only work sometimes. A breaker that trips every few weeks rather than every day. A faceplate that is warm. Each of those is a fault that has not finished developing yet.

A buzz from a switch or dimmer is not normal noise. It usually means a loose connection arcing, and arcing generates heat.
