Electrical Panel Replacement & Fuse Box Conversion
Replacing panels and fuse boxes that are obsolete, damaged, discontinued or simply worn out after decades of service.
Panels wear out, and some were never great to begin with
Breakers are mechanical devices. After thirty or forty years of thermal cycling, corrosion and dust, they do not always trip the way they were designed to. Bus bars pit, neutral bars loosen and enclosures rust where a sprinkler head or a basement leak found them.
Some older panel lines have also been discontinued entirely, which means replacement breakers are either unavailable or only available second-hand from unverified sources. Home inspectors and insurance carriers know these panels by name, and increasingly they are asking homeowners to replace them before a policy is written or a sale closes.
- Fuse boxes still serving a modern household
- Panels with rust, moisture staining or heat discoloration
- Breakers that feel loose, warm or refuse to reset
- Burning smells, buzzing or flickering when large loads start
- Panels flagged by an inspector, appraiser or insurer
Fuse box conversions
Plenty of homes in Denver's older neighborhoods still run on screw-in fuses. They can work, but they offer no ground-fault or arc-fault protection, they invite the dangerous habit of over-fusing a circuit, and they make ordinary modern life inconvenient.
Converting to a breaker panel modernizes protection for the whole house. We transfer the existing circuits, add GFCI and AFCI protection where code requires it, correct the grounding, and leave you with a labeled panel that any future electrician can read at a glance.
Honest replacement recommendations
Not every aging panel needs to come off the wall tomorrow. Sometimes the right answer is a breaker replacement, a torque-and-inspect service, or a plan to replace it during a remodel next spring.
We tell you what we would do in our own house, document what we found with photos, and let you decide. This trade is a long game for us, so we would rather earn your trust than sell you a panel you do not need yet.

Pricing
What moves the price on this job
We quote after seeing the equipment, because these details change the number more than anything else.
- Panel size and number of circuits to transfer
- Fuse box conversion versus straight breaker panel swap
- Condition of existing branch wiring and grounding
- Water or heat damage to the enclosure area
- Whether capacity is being increased at the same time
- Permit and inspection fees
Monthly payments available through Hearth
Prequalifying takes about a minute and uses a soft credit check, so seeing your options does not affect your credit score.
FAQ
Common questions
Is my old panel dangerous?
It depends on the panel, its condition and how it has been loaded. We inspect and photograph the equipment and give you an honest assessment rather than a blanket scare.
Can you replace a panel without upgrading the amperage?
Yes. A straight replacement at the same service size is common and costs less than a full amperage upgrade.
Will my insurance company require replacement?
Some carriers ask for replacement of certain older panel types or fuse boxes before binding a policy. Bring us the letter and we will quote exactly what they are asking for.
What happens to my old panel?
We remove and recycle it, patch the wall opening where practical, and leave the space clean.
How long is the power off during a panel replacement?
Usually four to six hours. We give you the window at the estimate so you can plan around refrigerators, medical equipment or a work-from-home day.
Do you replace Federal Pacific, Zinsco and Challenger panels?
Constantly. Those panels are the most common replacement we do in older Denver and Aurora homes, and we will show you photos of what is behind your cover plate before quoting.
How much does panel replacement cost in the Denver metro?
It depends on service size, the condition of the meter and mast, grounding work and the jurisdiction's fees. You get one fixed written price after we see the equipment, and no change orders after that.
How soon can you replace my panel?
Most replacements are scheduled within one to two weeks. If your panel is arcing, burning or you have lost half the house, tell us on the call and we will move you up.
Do I need a permit to replace an electrical panel?
Yes. Panel replacement is permitted and inspected work everywhere we operate. We pull it, meet the inspector and close the permit so it never becomes a problem at resale.
Is my new panel under warranty?
Yes. Breakers and equipment carry the manufacturer's warranty, and our workmanship is warrantied on top of it. The terms are written on your estimate, not just spoken.
Still deciding?
The fastest way to get a real answer for your home is to have a tech open the panel. The on-site estimate is free, and you leave with a written price for replacements.
