A panel replacement is a permit, a load calculation and an inspection before it is a piece of hardware: the service disconnect, the grounding and bonding, the breaker layout and the Town of Windsor’s electrical permit all change together. Precision Service Electric replaces panels and services across Windsor, and will tell you honestly whether you need a like-for-like swap or a service upgrade — the difference is thousands of dollars and a lot of unnecessary work if you get it wrong. Call 970-593-3190.
Why Windsor Panels Get Replaced
Panels are replaced for four reasons: the equipment has failed, the equipment is a known hazard, the panel has no space left for circuits the house needs, or the service is too small for what the house now runs. Only the first two are emergencies. The other two are capacity questions, and they are answered with arithmetic rather than opinion.
Houses in Windsor’s newer subdivisions — Water Valley, Pelican Lakes, RainDance, Highpointe — usually have 200-amp service and space to spare. Older homes closer to the original town core are more likely to have a 100-amp service, a full panel, or equipment from a manufacturer whose breakers are no longer made.
Repair or Replace: How to Tell
Signs a Panel Is Failing
Breakers that trip without an obvious overload, a panel that is warm to the touch, a burning smell, scorch marks or melted insulation at a breaker, or lights that dim when an appliance starts. Any of these means an electrician looks at it now, not next month.
Panels That Are a Known Hazard
Some panel lines are defective by design rather than by age — certain Federal Pacific and Zinsco equipment. Those panels do not become safe with new breakers; replacement is the fix, and an inspector will flag them at a sale. Aluminium branch wiring is a separate problem: swapping the panel does not repair the connections inside the walls, and those terminations are assessed and repaired to an accepted method on their own.
Panels That Are Merely Full
A full panel with a healthy service is a different problem from a failing panel. Sometimes a subpanel solves it; sometimes a tandem breaker is legal and adequate; sometimes the honest answer is that the house needs more service capacity. A quote that starts with “you need a new panel” before anyone has counted the load is not a diagnosis.
Like-for-Like Replacement vs. Service Upgrade
A like-for-like replacement swaps the panel for one of the same rating, reusing the existing service conductors and meter. It restores safety and adds modern breaker spaces without changing the service size.
A service upgrade raises the capacity — commonly to 200 amps — and may involve the meter base, the service entrance conductors, the grounding electrode system and coordination with the utility. That is a larger job with a larger permit scope, and it is only correct when the load requires it: a heat pump, an EV charger, a shop, an ADU or a finished basement with electric heat.
What the Panel Has to Support Next
The reason to do the arithmetic before choosing hardware is that the panel is the one part of the electrical system you do not want to revisit. An EV charger draws 32 or 40 amps continuously on the 40- or 50-amp circuits most homes use, and 48 amps on a 60-amp hardwired circuit. A heat pump conversion adds another. A basement finish adds circuits and often a subpanel. If any of those are on the horizon, a replacement that ignores them is a stopgap.
We calculate the existing load first — square footage, appliances, heating and cooling, range, dryer, water heater — and then add the planned loads. That calculation is what determines whether the answer is a panel, a service, or neither.
Permits and Inspection in Windsor
A panel replacement or service upgrade is permitted electrical work in Windsor. The Town of Windsor issues the electrical permit, and inspections run through SAFEbuilt at 970-674-1036. The Town adopted the 2024 I-Codes effective January 1, 2026. Grounding, bonding and service requirements come from the NEC edition the Town enforces, and the permit office confirms that edition when the permit is issued.
Precision Service Electric is licensed and insured under Colorado licence #3918 and pulls the permit for the work; the passed inspection is the document that proves the installation was done to code.
What the Work Involves
The utility is scheduled for a disconnect, the old panel is removed, the new one is set and landed, circuits are identified and re-terminated, the grounding and bonding are brought up to current requirements, and the panel is labelled. Then the inspection, then re-energising.
A like-for-like swap in an accessible garage is usually a one-day job. A service upgrade that involves the meter base and the service entrance is longer, and the utility’s schedule is part of the timeline.
What a Panel Replacement Costs in Windsor
Published local panel pricing varies by company and by what the price includes, and any number quoted before the panel is opened is a guess. What actually moves the price: like-for-like versus service upgrade, whether the meter base and service entrance conductors are replaced, the condition of the existing wiring, access to the panel, and permit fees.
The two things worth knowing before you call anyone: a like-for-like swap costs a fraction of a service upgrade, and the load calculation — not the age of the panel — decides which one you need.
Serving Windsor and Northern Colorado
We replace panels and upgrade services throughout Windsor, including Water Valley, Pelican Lakes, RainDance, Highpointe and the 80550 ZIP code, and across the communities we serve from our Loveland shop: Fort Collins, Loveland, Berthoud, Johnstown, Greeley, Longmont, Firestone, Timnath, Severance and Eaton.

“I had two heavier duty lines run ~15ft from the panel in my basement to the exterior for an EV charger and a minisplit system. There were a few options for placement I had in mind, and Bill was very patient in explaining the pros/cons for each. The quote was very reasonable, and their work was very well done. I'll definitely be using Precision for future electrical work!”

Frequently Asked Questions
Do I need a permit to replace my electrical panel in Windsor?
Yes. A panel replacement or service upgrade is permitted electrical work. The Town of Windsor issues the permit and inspections run through SAFEbuilt at 970-674-1036, against the adopted electrical code and the Town’s 2024 building codes, effective January 1, 2026.
How do I know if I need a replacement or an upgrade?
Replacement restores the same capacity with modern equipment; an upgrade raises the service size, usually to 200 amps, and may involve the meter base and service entrance. The difference is decided by a load calculation and by what the house will run in the next few years — not by the panel’s age alone.
How long does a panel replacement take?
A like-for-like swap in an accessible location is typically a one-day job, plus the inspection. A service upgrade takes longer because the meter base and service entrance conductors are involved and the utility has to schedule a disconnect and reconnect.
Can you replace the panel without shutting off power?
No — the service has to be disconnected for the work. That is scheduled with the utility, and we plan the day so the outage is as short as the job allows.
Will a new panel add value to my house?
A compliant panel with spare capacity removes an objection at sale and supports the loads buyers now expect: an EV charger, a heat pump, a finished basement. A panel that an inspector flags does the opposite.
Do I need a 200-amp service for an EV charger?
Not necessarily. Many 100-amp services can carry a 40-amp charger circuit; the load calculation decides. If the house also has electric heat or a heat pump, the answer can change.
