Our Crews Run From Key West to Key Largo
A Commercial Market That Demands Phasing
According to the U.S. Census Bureau, Monroe County had 4,154 employer establishments in 2023.
A Commercial Market That Demands Phasing
Most are occupied buildings: hotels, marinas, restaurants, condo associations, storage facilities, government offices that cannot absorb a full shutdown for a panel upgrade. Retrofit work runs through phased outages, temporary power services, and weekend cutovers.
Three Offices, One Service Area
Our main office sits at 3255 Flagler Ave in Key West, with a Naples office covering Naples to Fort Myers, and a new Summerland Key headquarters opening soon with a two-story stocked warehouse. Keys crews dispatch from Key West to Key Largo. Southwest Florida work runs through the Naples office on a separate dispatch.
What Storm Season Does to Aging Gear
Retrofit Problems We Take On
Key West averages 40.44 inches of rain a year, and about 65% of it falls between June and October, per the NOAA National Weather Service Key West. Storm-season moisture concentrates the stress on aging distribution gear. The question we hear from buyers is whether you can run a distribution panel upgrade in an occupied building without shutting it down.
Aging Panels in Coastal Buildings
Salt air and humidity degrade terminations, breakers, and bus bars faster on coastal commercial gear. Routine maintenance catches corrosion before it trips circuits.
- Nuisance trips on existing distribution
- Corroded lugs and bus connections
- Heat damage at undersized feeders
Outages You Cannot Schedule
Hotels, marinas, and restaurants need a retrofit phased around occupancy, not a weekend shutdown. Our team maps the outage to protect operations and meet facility requirements.
- Temporary power planning on site
- Phased cutovers in occupied wings
- Tenant and guest notification scope
Capacity Already Maxed Out
Existing panels and feeders run out of room before new equipment, EV chargers, or HVAC loads arrive. We offer load analysis and redistribution planning before the new equipment lands.
- Spare-circuit and load analysis
- Feeder redistribution and resizing
- Sub-panel additions for new loads
Scope Confusion at Bid Stage
Buyers sometimes mistake a distribution retrofit for upstream switchgear installation, or for a full new electrical system. Clear scope boundaries ensure the right contractor handles the right gear.
- Clear scope boundaries up front
- Service-calc decision on upgrades
- Right contractor for the right gear
Four Ways We Scope It
Scope Options for Distribution Retrofit
Distribution Panel Upgrade
For commercial buildings replacing an aging or failing distribution panel with a new NEC-compliant panel of similar or expanded capacity. Includes load review, panel specification, sealed-plan submittal, and cutover planning. Most runs as a single-phase outage when service capacity does not change at the meter, with the new electrical systems verified for safety and code compliance before energization.
Feeder and Sub-Panel Redistribution
When existing feeders or sub-panels run hot, are undersized, or block planned load additions. Includes feeder resizing, sub-panel relocations, circuit redistribution across existing distribution gear, and code review for the altered scope. Done right, redistribution restores efficient power flow and energy efficiency across the facility.
Capacity and Load Additions
For facilities adding HVAC equipment, EV charging, kitchen loads, or tenant build-outs that exceed existing distribution headroom. Includes service-calculation review, decision on whether utility coordination is required, sub-panel additions, and integration with the existing layout for optimal performance under the added demand. Whole-building rebuilds route to new construction electrical instead.
Distribution Gear Retrofit
For occupied properties retrofitting downstream distribution gear, lugs, breakers, or terminations after corrosion, heat damage, or insurance review. Includes thermal imaging, scope-of-replacement decision, and phased cutover. Stops short of main switchgear scope, with the goal of maintaining electrical equipment reliability on gear that is staying in service.
Why Commercial Buyers Hire Us for Retrofits
Precon Through Punch List
Precon Through Punch List
Commercial retrofit work in Key West fails on communication, not skill. We run the precon bid as a site walk, existing-condition review, sealed-plan coordination, and outage phasing decision before the contract is signed. That standard carried Wreckers Cay (250+ units), Little Palm Island, and The Capitana through completion. The proven track record on industrial facilities and multi-family complexes spans more than a decade in the Keys electrical industry.
Scope From Service Call to $12M Build
A retrofit can be a one-panel swap or a full distribution rework. With 55 licensed electricians, the same firm handles both ends: small service work in the $1K to $20K range, and full commercial projects from $100K into seven figures. The contractor scales with the project, state-certified since 2009, with minimizing downtime driving the phasing decisions on every job.
Calibrated Impedance Testing
A capability most Keys contractors do not carry: calibrated ground impedance testing certified for medical and government facility requirements. Useful on retrofit work where existing grounding documentation is missing, or where insurance or compliance review demands verified data. Precision testing supports the reliability and safety case when documentation is challenged.
From Site Walk to Closeout
How a Retrofit Project Runs
- 01
Site Walk and Load Review
On-site review of existing distribution panels, feeders, and downstream gear. The team verifies spare capacity, existing service size, and where the retrofit scope actually lives in the power distribution layout.
- 02
Sealed Plans and Utility Submittal
Sealed electrical plans, service calculations if required, and submittal to Keys Energy or Florida Keys Electric Cooperative. Plan review typically runs 10 to 15 days in FKEC territory. Commissioning coordination starts at this stage.
- 03
Outage Plan and Phasing
Map the cutover. Identify which feeders carry which loads, schedule the outage window around tenant or guest operations, and stage temporary power where needed. Planning protects operations and keeps critical systems working through the cutover.
- 04
Cutover and Installation
Execute the retrofit during the agreed window. Field crew handles panel set, feeder pulls, terminations, and load transfers across the planned phases in the Florida Keys facility. Repairs to damaged gear are folded into this phase.
- 05
Inspection, Testing, Closeout
Monroe County inspections, thermal imaging or impedance testing where scope calls for it, and closeout documentation including as-builts and updated panel schedules. Final commissioning verifies the systems are working before sign-off.

Retrofit Questions Buyers Ask Us
Distribution Retrofit FAQs
- How much downtime should a business expect during a commercial panel upgrade in the Florida Keys?
- Most distribution panel upgrades on occupied Keys buildings run as phased outages, not a full shutdown. A single-panel cutover on a building with one service is typically planned for an 8 to 12 hour window during off-hours, with temporary power available for critical loads. Larger feeder redistribution or multi-panel retrofits stage across multiple nights or weekends. We map the phasing during the precon walkthrough, not on the day of cutover. Tenant or guest notification scope is decided then as well, before any equipment is ordered.
- Do you provide fixed-price quotes on commercial retrofit work, or is it time and materials?
- Commercial distribution retrofit work is quoted as a fixed-price project after a site walk and load review. Small service-call work runs in the $1,000 to $20,000 range. Full commercial retrofits typically run from $100,000 into seven figures, depending on scope, gear, outage logistics, and utility coordination. The fixed price holds when the existing-condition scope matches what was bid at the site walk. Change-orders track to scope discovered after demo, not to estimating gaps.
- Do you handle retrofit work outside Key West, in the Middle and Upper Keys?
- Yes. Our Florida Keys crews dispatch from Key West to Key Largo, including Marathon, Islamorada, and Tavernier. The crew assignment depends on the site, the scope, and the planned outage window. For work in Naples or Southwest Florida, the project routes to our Naples office instead, on a separate dispatch. If you are not sure which office handles your area, call (305) 292-3369 and we will route the call. Field support covers both regions.
- What is the difference between a distribution panel upgrade and a switchgear retrofit?
- A distribution panel upgrade is downstream work, panels and feeders inside the facility. A switchgear retrofit is upstream, between the utility service and those panels. Downstream scope covers panels, sub-panels, feeders, breakers, and circuit redistribution. Upstream scope covers main switchgear, MCCs, and transfer switches. Sealed-plan content, utility coordination, and outage planning differ between the two. If your project is main gear or service entrance work, our switchgear installation page covers that scope directly. Most occupied-building retrofits we run are downstream distribution work.
- What payment terms do you accept on commercial retrofit projects?
- Commercial retrofits are contracted with milestone payments tied to deliverables. Milestones typically include bid acceptance, plan submittal, material order, cutover, and closeout. Specific terms are set in the project contract after scope is finalized at the site walk. Project billing runs through our admin office, and the project email is Admin@checkelectricllc.com. For smaller service-call work, terms are simpler and set at the time of the quote.
- What warranty applies to a distribution retrofit?
- Equipment warranties run through the manufacturer of the panel, gear, or device installed, and we register them on your behalf. Installation is performed by state-certified electricians under License # EC13004515, and the AHJ inspection sign-off goes into the project closeout package alongside as-builts and updated panel schedules, so the facility owner has it on file. Manufacturer claims on installed equipment are coordinated through us as the contractor of record.
- What happens if I'm not satisfied with the work after the retrofit is complete?
- The closeout walkthrough is where this gets resolved before the project is signed off. We walk the site with the customer or facility lead, demonstrate the retrofit, and address any item on the punch list before final payment. Escalation goes through the project manager assigned at precon, and the President's office is reachable when needed.
- What happens after I request a retrofit assessment?
- Calls and form submissions route through our Key West office, and a project manager follows up to confirm scope and site access. The next step is an on-site walk-through, usually 60 to 90 minutes, covering existing distribution gear, load review, and outage logistics. After the walk-through, we issue a sealed bid with phasing, timeline, and utility-coordination steps. Call (305) 292-3369 or submit the contact form to start that process.
