Electrical Panel Repairs, Panel Replacements & Service Upgrades (Heavy Ups)
The Heart of Your Home’s Electrical System: Handled by Master Electricians in Maryland, Washington DC & Northern Virginia
Do you need electric circuit breaker panel upgrades or replacement services?
TriStar Electric provides electrical panel repairs, full panel replacements, and service upgrades, the project electricians call a heavy up, for homeowners throughout central Maryland, Washington DC, and Northern Virginia. These are serious projects involving permits, county inspections, and utility company coordination, and they deserve serious oversight. We are a family-owned electrical contractor serving homeowners since 1991, our owners and managers are all master electricians, and on a project like this, the master electrician managing your job is the person you will be talking to, not a salesperson.
Electrical Panel Repairs & Troubleshooting
Breakers and panel components wear out and corrode over time, and the warning signs are ones you should never ignore: breakers that trip repeatedly, a burning smell near the panel, humming or buzzing sounds, or flickering lights throughout the house. Our electricians troubleshoot the actual cause, whether a worn breaker, a loose connection, or an overloaded circuit, and repair it properly.
Panel problems are not always dramatic, though. Some of the most important issues are the quiet ones: an outdated grounding system, mis-branded or incorrect breakers installed by a previous owner or handyman, or a panel with no surge protection defending your home’s electronics and appliances. That is why we recommend having your panel inspected once a year: a quick, inexpensive check that catches small problems before they become dangerous or expensive ones.
Electrical Panel Replacement
Some panels cannot be repaired responsibly; they need to go. If your home has a Federal Pacific, Zinsco/Sylvania, or Pushmatic panel, or an older split bus panel with no main breaker, you are living with equipment that is outdated at best and a documented fire risk at worst. These brands and designs are well known in the electrical trade for failing to trip when they should, and insurance companies increasingly flag them. Physical damage tells the same story: a deteriorated service cable, rust inside the panel, or scorching from a burned-up breaker all point toward replacement as the safest path forward.
When we replace a panel, we install a modern Square D main breaker panel, typically the Square D Homeline line, with QO or other quality brands like Leviton available depending on what fits your home and your goals best. Every circuit is properly labeled, properly grounded, and inspection-ready before we call the job done. If you are not sure what brand of panel is in your home right now, go take a look. If the label says Federal Pacific or Zinsco, we should talk.
Service Upgrades: the Heavy Up
Modern life demands more power than most older homes were built to deliver. If you are remodeling, adding an EV charger, installing a hot tub, or upgrading to major new appliances or HVAC equipment, your existing electrical service may not have the capacity to carry it. The answer is a service upgrade, known as a heavy up, bringing your home to 200 amps or more, depending on what your plans require.
A heavy up is not a one-day handyman job. It involves the county permit office, your utility company, a scheduled power disconnect, and multiple inspections, and this is exactly where TriStar Electric earns its keep. We handle the entire process from A to Z: the permits, the utility coordination, the installation, and the inspections, so the project actually moves instead of stalling in paperwork.
What to Expect: Our Panel Replacement & Heavy Up Process
Step 1: Site Assessment
We visit your home in person, gather everything needed for an accurate quote, and walk you through your options before any work begins. The goal is a price without surprises later, which is why this particular project starts with an in-person visit rather than a virtual estimate.
Step 2: Permits & Utility Coordination
We pull the local building permits and coordinate the power disconnect with your utility provider. Your part is simple: be home for the inspection on two occasions. We handle the rest.
Step 3: Installation Day
Our team removes the old equipment and installs your new panel with every circuit properly labeled and grounded, ready for inspection. Plan to be without power for most of the day. Afterward, our service department manager reviews the completed job with the install team, a second set of expert eyes on your project before the inspector ever arrives.
Step 4: Inspection & Power Restoration
A city or county inspector verifies the installation and releases it for final connection, and the utility company then makes the final connections to your home. From that point on, your electrical system is modern, safe, and ready for whatever you add next.
Frequently Asked Questions
How do I know if I need a service upgrade?
If you are planning to add a heavy electrical load such as an EV charger, new HVAC equipment, a hot tub, or a major renovation, your current service may not be enough. We will assess your existing service and planned loads and give you a straight answer about whether a heavy up is actually needed.
How long does a panel replacement take?
The installation itself typically takes one full day, with the power off for most of it. The complete process of permits, utility scheduling, installation, and final inspection can run from about a month to several months depending on your schedule, ours, and the utility company’s. We manage the timeline and see it through from start to finish so nothing falls through the cracks.
Is a permit required?
Yes. Any major panel work or service upgrade requires a permit: for your safety, for your insurance, and because the utility company must be involved in disconnecting and reconnecting your service. A contractor who offers to skip the permit is not doing you a favor.
Can I just add more breakers to my existing panel?
Sometimes. It depends on whether your panel has physical space and whether the bus bar can safely handle the additional load, something we verify with a load calculation, not a guess. In some cases a sub-panel or tandem breakers are the right answer. We will help you choose the option that is safest and most cost-effective for your situation.
Can I use a different brand of breaker if it fits in my panel?
No, and this surprises a lot of homeowners. Even when a breaker physically fits, mixing brands is against code, can void your equipment warranties, and can create insurance problems if something ever goes wrong. It is one of the most common issues we find and correct during panel inspections.
