Electrical Panel Upgrade & Replacement: Upgrade Your System. Protect Your Home. Power Your Future.
Your electrical panel is the heart of your home's electrical system.

Left unaddressed, an outdated or overloaded panel isn't just inconvenient. It's a genuine safety risk.

Why Panel Issues Are Common in Denver Metro Homes
Denver metro's housing stock reflects decades of changing electrical standards, and many older electrical systems simply weren't designed for today's electrical demand.
Homes built during the 1950s and 1960s commonly had 60-amp service panels. In the 1970s and 1980s, 100-amp service became standard.
At the time, that was enough.
Today's homes are dramatically different.
Modern electrical demand includes EV chargers, smart home systems, high-efficiency HVAC equipment, multiple refrigerators, home offices, entertainment systems, and far more electronics than older panels were ever designed to support.
Current code minimums start at 125 amps, while 200 amps has become the practical standard for most residential homes.
Colorado's rapid growth has also created a huge number of additions, basement finishes, garage conversions, and remodels, many adding electrical load to panels already operating near capacity.
And older Federal Pacific Stab-Lok and Zinsco panels, both known for documented safety concerns, still exist in many Denver metro homes today.
A panel upgrade is often one of the most valuable and important electrical improvements a homeowner can make.

Types of Panel Work We Handle
Every Panel Situation Is Different. Here's What We Do.
The most common residential panel upgrade we perform.
If your home currently has a 100-amp panel, or anything smaller, upgrading to 200 amps provides the capacity modern homes need for additional circuits, EV chargers, HVAC systems, and future growth.
For most Denver metro homes, this is the standard upgrade.
Designed for larger homes, high-demand electrical systems, multiple EV chargers, workshops, or major additions significantly increasing electrical demand.
Less common, but the correct solution when the load requires it.
Sometimes the problem is not capacity, it's safety or reliability.
If the panel itself is outdated, damaged, failing, or from a manufacturer with known safety issues, replacement at the same amperage may be the correct solution.
Federal Pacific Stab-Lok and Zinsco panels have well-documented breaker failure issues.
The primary concern is breakers failing to trip during overload conditions, removing the safety protection the breaker is supposed to provide.
If your home has either of these panel types, replacement is strongly recommended regardless of apparent condition.

When the main panel is full, or when additional power distribution is needed for garages, workshops, additions, or detached buildings, a properly sized subpanel is often the best solution.
We size and install subpanels correctly for the intended electrical load.
If the main breaker itself is failing, overheating, or tripping under normal load, we replace it safely and correctly.
Panel upgrades often require utility coordination involving the meter base and service entrance wiring.
We handle the process directly and coordinate with Xcel Energy or your utility provider to ensure the system is upgraded correctly from the utility connection to your panel.

The Electrical Panel Upgrade & Replacement Services Professionals
Honest Answer: For Most Denver Metro Homeowners, Yes.
A panel upgrade is a significant investment, and we understand that.
Here's how we evaluate it honestly.
A panel upgrade is usually worth it when:
• Your home has a Federal Pacific Stab-Lok or Zinsco panel
• Your home still operates on a 60-amp or 100-amp panel
• Your panel is completely full with no room for additional circuits
• You're installing an EV charger or adding major electrical demand
• Your insurance company requires an upgrade
• You're planning a major remodel or addition
• Your panel shows signs of overheating or damage
A panel upgrade may not be necessary when:
• Your existing 200-amp panel is modern, safe, and has available capacity
• The issue is isolated to one circuit rather than the entire panel
• Your home's electrical demand remains modest and the panel is operating properly
We never recommend a panel upgrade simply to sell a larger project.
Our electricians perform honest load calculations and explain clearly what your home actually needs and what it doesn't.
• Full electrical system evaluation and load calculation

1. How do I know if I need a panel upgrade?
The most common warning signs are constantly tripping breakers, overloaded circuits, flickering lights, warm panels, panels with no remaining breaker space, and homes still operating on 60-amp or 100-amp service.
Federal Pacific Stab-Lok and Zinsco panels also deserve replacement regardless of apparent condition because of their documented safety concerns.
The best way to know for certain is a professional load evaluation.
2. What size panel does my home need?
For most modern Denver metro homes, 200-amp service is the practical standard.
Current code minimums start at 125 amps, but most homes today benefit from 200 amps because of HVAC systems, EV chargers, appliances, and future electrical demand.
Larger homes or high-demand properties may require 400-amp service.
We perform full load calculations for every panel project.
3. What's the difference between a panel upgrade and a panel replacement?
A panel upgrade increases your home's electrical capacity, such as upgrading from 100 amps to 200 amps.
A panel replacement keeps the same capacity but replaces an outdated, damaged, or unsafe panel.
Some projects involve both at the same time.
We explain clearly which option your home actually needs.
4. How long does a panel upgrade take and will my power be off?
Most residential panel upgrades are completed within one day, typically four to eight hours depending on complexity.
Power must be temporarily shut off during the upgrade process.
If utility coordination is required for service entrance or meter work, we coordinate directly with Xcel Energy or the utility provider beforehand to minimize downtime.
5. Does a panel upgrade require a permit in Colorado?
Yes. Always.
Panel upgrades and replacements require permits and inspections in Colorado.
Permits ensure the work is independently inspected for safety and code compliance.
Unpermitted panel work creates serious liability during home sales and can affect insurance coverage.
We pull all required permits and coordinate inspections for every panel project.
6. How much does a panel upgrade cost?
Cost depends on the current panel size, desired capacity, installation complexity, utility coordination requirements, and permit fees.
A straightforward 100-amp to 200-amp upgrade differs significantly from a project involving service entrance replacement or major utility coordination.
We provide transparent detailed estimates after evaluating your specific system.
Financing options are available.
7. Is a Federal Pacific or Zinsco panel dangerous?
Yes.
Both Federal Pacific Stab-Lok and Zinsco panels have documented breaker failure issues involving breakers that fail to trip properly during overload conditions.
That means the panel's primary safety protection may not function correctly during dangerous electrical events.
Many insurance companies refuse coverage or increase premiums on homes with these panels.
We strongly recommend replacement regardless of the panel's visible condition.
8. Will a panel upgrade increase my home's value?
In most cases, yes.
A modern 200-amp panel signals to buyers that the home's electrical system is current, safe, and capable of supporting modern electrical demand.
It also removes one of the most common inspection concerns during real estate transactions and supports important future upgrades such as EV charging.
