St. Louis Fuse Box Replacement

Why Replacing the Fuse Stops Solving the Problem

Screwing in a new fuse restores power. It doesn't change how much power the house is pulling. If you're replacing fuses on the same circuit more than once or twice a year, the fuse is doing its job by telling you the circuit is overloaded beyond its rating. And a fuse someone oversized to stop the nuisance leaves wire unprotected in a wall you can't see.

What Drives the Cost of Replacing a Fuse Box

Costs for a fuse box-to-breaker panel conversion range between $1,100 and $4,000, with 200-amp service at the upper end. Your number depends on the house, so we look at it first.

Four things move the price on a fuse box replacement:

• The service size you land on – Keeping 100-amp service costs less than moving to 200 amps.
• Whether the meter base changes – Utility-side work adds labor and adds coordination.
• The condition of the branch wiring – Knob and tube or aluminum may need replacing before the new panel is safe to energize.
• Panel location and access – A box behind finished basement framing takes longer than one on an open wall.

We hand you a flat-rate price in writing before a toolbox opens. No hourly clock, and no different number on the invoice. If the total exceeds what you planned to spend at once, we offer financing options.

What Replacement Day Looks Like

We pull the permit and coordinate the inspection, because requirements across the metro vary and permitting is where these projects stall. You'll know the power-off window before we start it, and we schedule around pets, parking, and access.

Our electricians protect floors, label and organize the circuits in the new panel, and walk you through what changed before leaving. Every job comes with a 5-Year Parts & Labor Warranty at no extra cost, plus a transferable 10-Year upgrade for homeowners who keep up with maintenance.

Panel work often surfaces the rest of it: knob and tube rewiring, surge protection, a Generac standby generator, or the EV charger the old box had no room for. 

Frequently Asked Questions About Fuse Box Replacement

The following are the questions we hear most on the first call. Our phone is staffed around the clock if yours isn't answered here.

How Much Should It Cost to Replace a Fuse Box?

Most conversions cost between $1,100 and $4,000. We quote a flat rate after evaluating your panel, so the figure you approve is the figure on the invoice unless the scope changes.

Can I Replace a Fuse Box Myself?

Replacing a service panel means working where utility power enters the house, and the conductors ahead of the main stay live even with the main shut off. The City of St. Louis issues electrical permits to licensed contractors and, in limited cases, to homeowners who pass a code test.

How Long Does a Fuse Box Replacement Take?

Most single-panel replacements finish in one day, with the power off for part of it. If the meter base or branch wiring needs work, the schedule will be extended, and you'll see that reflected in the quote.

Will I Need to Rewire the Whole House?

Not usually. A new breaker panel works with existing wiring that's sound, and we recommend rewiring only where we find knob and tube, aluminum branch circuits, or damaged conductors.
