Where the money is
Do you actually need 200 amps?
This deserves a straight answer rather than a default.
If your panel is simply full rather than under-supplied, replacing the panel alone, or adding a subpanel, is often the correct answer at a fraction of the price.
- The calculation shows you're at or beyond capacity
- You're adding significant electric load — EV charging plus a heat pump, for example
- You're opening the service anyway and the incremental cost is modest compared with doing it twice
It accounts for the property's square footage, heating and cooling equipment, cooking appliances, water heating, laundry, and any large dedicated loads like EV charging, a hot tub, or a workshop. It produces a number.
That number tells you whether your existing service is genuinely insufficient, or simply out of physical space — different problems with very different prices.
We run the calculation and show you the result. If 100 amps is sufficient for your property, that's what you'll be told.
Two jobs, one name
What each one actually fixes
Warning signs
Signs you need a panel upgrade
No space left for new circuits
The most common trigger. You want a circuit for a workshop, an EV charger, an addition, or a hot tub, and there's nowhere to land it.
Tandem breakers or double-tapped wires
Two slim breakers in one slot, or two conductors under a single terminal. Sometimes acceptable by design, often not — and either way, a sign the panel is beyond what it was laid out for.
A fuse box rather than breakers
Fuse panels aren't automatically unsafe if intact, but they're limited in capacity, easy to defeat with an oversized fuse, and many insurers now object to them.
60-amp or 100-amp service with modern demands
Adequate when installed. A modern household with electric cooking, air conditioning, a heat pump, or EV charging can outgrow it — though not always, which is what the load calculation is for.
Breakers that trip regularly
Repeated tripping on multiple circuits usually means the panel and its circuits are carrying more than they were designed for.
Lights dimming when large appliances start
A momentary dip when the air conditioner or a well pump kicks in can indicate the service is working near its limit.
Heat, buzzing, rust, or scorching at the panel
Warm breakers, a humming panel, corrosion, or discolouration around terminals. Any of these should be looked at promptly rather than scheduled at leisure.
The panel is decades old
Panels don't have a hard expiry, but breakers are mechanical devices and bus bars corrode. A panel installed generations ago is worth an assessment.
Insurance questions or a failed inspection
Insurers and home inspectors flag certain panels and service sizes routinely. If yours has come up, you're not imagining it.
Check your label
Panels with known problems
Federal Pacific Stab-Lok, Zinsco and Sylvania-Zinsco, and to a lesser extent Pushmatic and Challenger panels are the names that come up repeatedly in inspection reports and insurer questionnaires.
Replacement parts for several are also difficult or impossible to source legitimately, which matters when a breaker fails.
If your panel label shows one of these, it's worth an assessment. That isn't a sales tactic — it's the reason home inspectors flag them and the reason some insurers ask.
Aluminum branch circuit wiring from certain eras is a separate but related concern that frequently surfaces during panel work. If it's present, we'll tell you and explain the options.
Ask every bidder
What's missing from a cheap panel quote
If one quote is dramatically lower than the others, it's usually one or more of these.
Seven common omissions
- Grounding and bonding. Older properties frequently have grounding electrode systems that no longer meet current requirements. Replacing a panel typically triggers bringing this up to standard — ground rods, bonding to water and gas piping where required, correct conductor sizing. A quote that ignores it either doesn't know or is planning to raise it mid-job.
- AFCI and GFCI protection. A new panel usually means circuits get the protection current code requires. Those breakers cost meaningfully more than standard ones, and leaving them out makes the number look better.
- Permit and inspection fees. Non-negotiable, and occasionally omitted.
- Meter base and service entrance. On a service upgrade, the meter base, conductors, and mast frequently need replacing too. Quoting the panel alone understates the job.
- Utility coordination. Disconnect and reconnect has to be scheduled, and in some areas carries a fee.
- Drywall and finish work. New panels are sometimes larger than the old ones. Ask what condition the wall will be left in.
- Circuit labelling and testing. Should be included. Ask.
Ask every bidder which of these are in their number. The answers will usually explain the spread.
Why Cascade calls us
What you get when you call Summit
We calculate before we recommend
Every upgrade recommendation comes with the load numbers behind it. You should be able to see why.
We quote the whole job

Licensed, permitted, inspected
We pull the permit, coordinate the utility disconnect and reconnect, and hand you the sign-off documentation.
Clear communication about power being off
You'll know in advance how long the property will be without power and how to plan around it.
Labelled properly at the end
Every circuit identified and legibly labelled. It sounds minor until the next emergency, when it isn't.
What we do
Our panel services in Cascade, IA
Panel replacement
New panel on the existing service, with all circuits re-terminated, tested, and labelled.
Service upgrades
Increasing incoming capacity, coordinated with the utility, including meter base, service entrance conductors, and mast or riser where required.
Subpanel installation
Adding capacity for a garage, workshop, addition, or basement suite without necessarily replacing the main panel.
Load calculations
Establishing what your property actually demands — before a purchase decision, a renovation, or an EV charger install.
Fuse box replacement
Converting fuse panels to modern breaker panels, with the grounding and protection updates that usually accompany it.
Obsolete and known-problem panels
Replacing panel types with documented failure histories or unavailable parts.
Grounding and bonding upgrades
Bringing the grounding electrode system and bonding up to current requirements — frequently required during panel work.
AFCI and GFCI protection
Adding required arc-fault and ground-fault protection as part of the new panel.
EV charger and high-load preparation
Capacity assessment and dedicated circuits for chargers, heat pumps, hot tubs, and shop equipment.
Panel relocation
Moving a panel that's inaccessible, in a prohibited location, or in the way of a renovation.
On the day
What the job actually involves
- Permit first. Applied for and issued before work begins.
- Utility coordination. Power is disconnected at the service for the swap and reconnected after. Scheduling this is often what sets the date.
- Power off for most of a day. Typically several hours to a full working day for a straightforward replacement. We'll give you a realistic window so you can plan refrigeration, work, and childcare around it.
- Old panel removed, new panel mounted, and every circuit re-terminated into the new enclosure.
- Grounding and bonding brought up to current requirements.
- Protection installed — AFCI and GFCI where required.
- Testing and labelling of every circuit.
- Inspection by the authority having jurisdiction, coordinated by us.
- Documentation handed over — permit, inspection sign-off, and a legible panel schedule.
Service upgrades add meter base and service entrance work, and sometimes a mast or riser, which extends the timeline.
How it works
Our process
-
Assessment
We examine the existing panel, service size, grounding, and condition, and look at what you're planning to add.
-
Load calculation
The numbers that determine whether you need a panel, a service upgrade, or a subpanel.
-
Written quote
Full scope — panel, grounding, protection, permit, utility coordination, and wall condition at handover. One number.
-
Permit and utility scheduling
Permit pulled, disconnect and reconnect arranged, and your outage window confirmed.
-
Installation
Panel replaced, circuits re-terminated, grounding and bonding completed, protection installed.
-
Testing, labelling and inspection
Every circuit tested and labelled, inspection completed, documentation handed over.
The indirect costs
Insurance, inspections, and resale
Panels come up in three places where they cost you money indirectly.
- Insurance. Some insurers decline, surcharge, or require replacement for fuse panels, certain known-problem brands, 60-amp service, and aluminum branch wiring. If you've had a policy question or a renewal condition, the panel is a common reason.
- Home inspections. Panel age, brand, double-tapping, missing protection, and inadequate grounding are standard findings. They become negotiating points at exactly the moment you have least leverage.
- Resale. A permitted, inspected panel upgrade with documentation is an asset in a transaction. An undocumented one raises questions.
Keep the permit and inspection paperwork somewhere you'll find it later. It's worth more than most people expect.
One step ahead
Planning for what's coming
If you're upgrading anyway, it's worth thinking about what's next.
- EV charging is the most common driver now. A charger needs a dedicated circuit and real capacity, and installing the panel with that in mind is far cheaper than revisiting it in two years.
- Heat pumps and electric heating add substantial load and are increasingly common in renovations.
- Induction cooking carries a different demand profile than gas.
- Solar and battery storage have their own interconnection requirements, and the panel is part of that conversation.
- Workshops, garages, and suites are usually better served by a subpanel than by long runs from the main.
Tell us what's on the horizon and the calculation can account for it now rather than later.
Commercial
Commercial panel upgrades
We handle panels and distribution for restaurants, retail, offices, warehouses, and multi-unit residential buildings across Cascade.
Commercial work introduces three-phase supply, larger service equipment, distribution panels across multiple areas, and load profiles driven by equipment rather than occupancy. Kitchen equipment, HVAC, refrigeration, and machinery all change the calculation substantially.
Shutdown planning matters more here than anywhere: we define the outage window in advance and schedule around trading or production where the work would otherwise close you.
Pricing
What affects the cost
- Panel replacement or full service upgrade — the largest single factor.
- Service size — and whether the utility, meter base, and service entrance are involved.
- Number of circuits — more circuits means more termination and testing.
- Grounding and bonding work — how far the existing system is from current requirements.
- Protection requirements — AFCI and GFCI breakers cost more than standard.
- Panel location — accessible basement wall versus a cramped closet or a relocation.
- Mast, riser, or meter work — common on service upgrades.
- Permits, inspection, and utility fees — vary by jurisdiction.
- Wall repair — where the new enclosure differs in size.

Questions
Frequently asked questions
Do I need 200-amp service?
Only if the load calculation says so. Many homes run fine on 100 amps. If your panel is simply full rather than under-supplied, replacing the panel or adding a subpanel is often the cheaper correct answer.
How much does a panel upgrade cost in Cascade?
It depends mostly on whether you need a panel replacement or a full service upgrade involving the utility and meter. You'll get one written quote covering permits, grounding, and protection rather than just the panel.
How do I know what service size I have?
Look at the main breaker rating — usually marked 60, 100, 125, or 200. Photograph it along with the panel label and we can tell you a great deal before visiting.
Why is one quote so much lower than the others?
Usually grounding and bonding, AFCI and GFCI breakers, permits, or meter and service entrance work left out of the number. Ask each bidder specifically which of those are included.
How long will my power be off?
Typically several hours to a full working day for a straightforward replacement. You'll get a realistic window in advance so you can plan.
Do I need a permit?
Yes. Panel work is permitted, inspected work in essentially every jurisdiction. We handle the permit and inspection and give you the documentation.
My panel is a Federal Pacific or Zinsco. Is that a problem?
Those brands have documented histories of breakers failing to trip, and parts are difficult to source. It's why inspectors flag them and insurers ask. Worth an assessment.
Can I add circuits without replacing the panel?
Sometimes — if there's physical space and the service supports the load. Where there's capacity but no space, a subpanel is often the answer.
Is a subpanel cheaper than a full upgrade?
Frequently, yes, where the service has capacity and the issue is space. It's the first thing worth checking before committing to a service upgrade.
Will a panel upgrade fix my flickering lights?
Sometimes — if the cause is an overloaded or failing panel. Flickering can also indicate a neutral fault or a loose connection elsewhere, which is a different repair. Diagnosis comes first.
Do I need an upgrade before installing an EV charger?
Depends on your existing capacity and what else is on the service. A load calculation answers it. Some homes need nothing; others need a service upgrade.
Will my insurance require this?
Some insurers decline or surcharge for fuse panels, certain panel brands, 60-amp service, or aluminum wiring. If your insurer has raised it, the upgrade usually resolves it — keep the documentation.
What condition will the wall be left in?
Ask any contractor this. New enclosures are sometimes a different size than the old one. We'll tell you up front what's included and where our scope ends.
Find out which job you actually need
A full panel and an under-supplied service look identical from the outside and cost very different amounts to fix. The load calculation is what separates them, and it should come before the recommendation rather than after.
