Inspection-ready scope
Existing and proposed ratings, equipment, circuits, grounding, and service work should be explicit.

Electrical Panel Upgrades in Prospect Heights, IL
A Prospect Heights panel scope should be written so the inspector, owner, and electrician are discussing the same equipment and sequence. AGE separates diagnosis, panel replacement, service revision, circuit corrections, and restoration before the controlled outage.

Direct planning answer
What should this project cost and how long can it take?
Comparable northwest-suburban planning bands are about $2,000–$6,000 for a subpanel, $3,500–$8,500+ for a panel replacement, and $5,500–$12,000+ for a broader service revision. The quote must say whether it adds circuit space, replaces distribution equipment, or actually changes utility-service capacity.
Straightforward panel replacement field work may fit in one scheduled workday, but the controlled outage is only one part of the timeline. Permit review, equipment availability, utility coordination, service conductors, meter work, relocation, grounding corrections, and inspections can extend the calendar schedule or require additional workdays.
Planning ranges—not quotes
The property, equipment, access, existing conditions, permit, utility, and restoration scope determine AGE Electric’s quote.
Prospect Heights project factors
What changes the scope here
These are property and planning conditions—not generic city-name substitutions.
Advance scheduling
Permit review and designated inspection availability can be longer than the field outage.
Corrections before concealment
Accessible issues discovered during transfer should be documented and resolved before affected work is covered.

Permit and inspection planning for Prospect Heights
Prospect Heights publishes permit and inspection requirements, including advance scheduling and specific electrical-inspection windows. Inspection availability should be built into the project calendar before finishes close or a service outage is promised.

Compare the same scope—not just totals
Each band carries assumptions. A low number and a high number are not comparable if one omits permits, routing, equipment, restoration, or enabling work.
| Comparable scope | Planning range | What it assumes | What can change it |
|---|---|---|---|
| Subpanel installation | $2,000–$6,000 | Additional distribution with adequate upstream service and a defined feeder route | A subpanel creates circuit space; it does not automatically increase service capacity |
| Panel replacement | $3,500–$8,500+ | Comparable equipment replacement, circuit transfer, labeling, grounding review, permit, and testing | Meter, service lateral, relocation, exterior restoration, and utility work may be separate |
| Broader service revision | $5,500–$12,000+ | Service equipment, conductors, meter, exterior routing, or substantial corrections | Utility requirements, underground work, property conditions, and restoration materially change cost |
Estimate comparison checklist
What the written scope should identify
Use this list to compare the same work from one proposal to another and to expose missing assumptions before the project starts.
- Existing and proposed equipment ratings
- Panel, subpanel, meter, disconnect, feeder, and grounding scope
- Circuit transfers, corrections, surge protection, labeling, and testing
- Permit, inspection, utility, and shutdown responsibilities
- Wall, siding, masonry, trench, landscaping, and finish-restoration exclusions
Prospect Heights questions
Answers before equipment or scheduling
These answers keep capacity, access, approvals, cost, and timing visible instead of hiding them behind “it depends.”
When should a Prospect Heights panel inspection be scheduled?
Confirm the City’s current notice and inspection windows once the permit and work sequence are known. The outage, inspection, reconnection, and finish work should be coordinated—not booked as unrelated events.
Will a new panel lower my electric bill?
A panel generally does not create energy savings by itself. It may address condition, safety, distribution, or capacity, while actual usage and utility rates drive the bill.
Can a subpanel avoid a service upgrade?
It may solve a distribution-space problem, but it cannot create upstream capacity. A load calculation and equipment review determine whether the existing service supports the planned loads.
How long will power be off?
The controlled outage depends on equipment, circuit condition, utility and inspection sequence, and corrections discovered after opening. The proposal should distinguish outage time from total project lead time.
