A panel replacement in Longmont runs into a fact that surprises people: the utility that feeds the house is the city itself. Longmont Power & Communications has supplied the town since 1912, it reviews the service work on its own system, and it performs the disconnect and reconnect on a service change. That coordination — not the panel swap itself — is usually what sets the schedule. Precision Service Electric replaces panels and upgrades services in Longmont and works the city side of the job as part of the scope. Call 970-593-3190.
What Actually Brings a Longmont Panel to the End of Its Life
Longmont’s housing runs from century-old houses near downtown to subdivisions built in the last decade, and the two ends of that range fail differently. In the older stock the problem is often capacity and age together: a 100-amp service, a panel whose breakers are no longer made, and wiring that has been extended by three owners. In newer neighbourhoods the equipment is usually sound and the issue is space — a full panel with no room for the circuits a household now wants.
Then there is the failure case, which is not about age at all: a breaker that trips under no load, a panel warm to the touch, scorch marks or a hot smell at a termination. Any of those means an electrician looks at it now.
Repair, Replace, or Upgrade the Service?
When Repair Is the Right Answer
A single failed breaker, a loose neutral on one circuit, a burned lug that can be re-terminated — these are repairs, and they are worth doing properly rather than using as an excuse to sell a panel. The diagnosis comes first.
When the Panel Has to Go
Federal Pacific Stab-Lok and Zinsco equipment is defective by design rather than by age, and new breakers in the old enclosure do not make either safe. The remedy is a full replacement, or a listed replacement interior where the enclosure is compatible and such a part exists for it. Aluminium branch wiring is a separate problem that a new panel does not fix.
When the Service Itself Is Too Small
A service upgrade changes the rating, not just the box: new service-entrance conductors, a new meter base, and work on the utility side. A 200-amp panel fed by a 100-amp service is still a 100-amp house, which is the most common misunderstanding in panel quotes.
The Load Calculation Is the Whole Conversation
Sizing starts from the house, not from the panel: the code-defined floor area the load calculation uses (which includes qualifying unfinished space), the range, the dryer, the water heater, heating and cooling, and any large motor circuits.
That arithmetic decides whether you are buying a like-for-like panel or a service upgrade — and the difference is thousands of dollars. Anyone quoting before doing it is guessing.
Longmont’s Permit and Licence Chain
Electrical permits come from City of Longmont Building Services at the Development Services Center, 385 Kimbark Street — 303-651-8332. Applications and inspections run through the Accela Citizen Access portal, and inspection requests have to be in by 4:00 p.m. the business day before.
The licensing point deserves attention if you are comparing quotes. The City requires a Longmont contractor licence under Municipal Code 16.48.030, states plainly that it does not offer reciprocal licensing with other jurisdictions, and requires electricians to hold a current Colorado master licence plus a contractor licence. A crew that is licensed in a neighbouring city is not licensed here by default.
On a service change the utility work sits alongside the permit: LPC reviews the service application and performs the disconnect and reconnect, which is why the outage window on an upgrade is longer than on a like-for-like swap and depends on the utility’s schedule as much as ours.
Grounding, Bonding and Surge Protection
A panel replacement is the moment the grounding electrode system gets looked at properly — the ground rod or ufer connection, the water-pipe bond, equipment grounding conductors, and the bonding of any metal gas piping. In a house that has been added onto, this is where the surprises are, and it is not optional work.
Where the adopted code requires it, replacement service equipment has to include a listed surge protective device — that is a requirement, not an upgrade. An SPD does not replace grounding and will not stop every surge, but it is inexpensive relative to what it protects and easiest to fit while the cover is off.
Install Day, Realistically
A like-for-like panel swap is normally a working day: power off, old equipment out, new panel in, circuits re-terminated and labelled, cover on. A service upgrade stretches across the utility’s involvement — the meter base and drop change, the inspection, and the reconnect.
What we will not do is promise a single number for the outage before the panel has been opened and the service looked at. The quote states the expected window, and if the utility’s schedule moves, you hear about it before the day rather than during it.
What Moves the Price
Like-for-like versus upgrade is the biggest single variable. After that: whether the meter base and service-entrance conductors are replaced, the condition of the existing wiring where it lands in the panel, whether the panel has to move to meet clearance requirements, access and finish repair, and permit fees.
A failed panel in a finished basement wall and a 200-amp panel on an exterior wall are not the same job, and a quote that treats them as one will change once someone opens the wall.

Frequently Asked Questions
How long is the power off for a panel replacement?
A like-for-like swap is usually one working day. A service upgrade adds the meter base, the LPC disconnect and reconnect, and an inspection between them, so it spans more than a day and partly depends on the utility’s schedule.
Do I need a permit in Longmont?
Yes. Panel replacement, subpanel additions and service upgrades are permitted work in Longmont, applied for through Building Services and inspected by the City.
Can the panel be replaced without upgrading the service?
Yes, and that is the correct scope when the load calculation says the service rating is adequate. It is also the cheaper job — a new panel on the same service does not add capacity.
My panel is a Federal Pacific — how urgent is it?
Not a same-day emergency, but not something to defer indefinitely. Those panels are defective by design, cannot be made safe with new breakers, and are flagged at resale.
Will a new panel make room for an EV charger?
Only if the service has capacity to give. The charger is a large continuous load; the calculation decides whether it fits, whether the service needs upgrading, or whether a lower-amperage circuit is the right answer.
Who handles the utility disconnect?
Longmont Power & Communications does. LPC reviews the service work and performs the disconnect and reconnect, and we coordinate that as part of the job so the inspection and the reconnect line up.
