Serving Northern Virginia

Electrical panel upgrades and 200-amp service across Northern Virginia

Panel upgrades and 200-amp service, permitted

An overloaded or outdated electrical panel is a safety issue and a bottleneck. If you're adding an EV charger, a heat pump, a hot tub, or a kitchen remodel, or if you still have a fuse box or a recalled panel, you may be maxed out. Our licensed electricians upgrade panels, bump service up to 200 amps, add sub-panels and circuits, and replace old fuse boxes, all permitted and inspected so it's done right.

No corners cut on panel work

Panel work is where cut corners turn dangerous, so we cut none. Our licensed electricians pull the permit, build the upgrade to code, and stand there for the inspection on every job. Panel replacement estimates cost nothing, financing is available through our partners, and the company behind the work has been family-owned since 1956.

Free panel estimates booked with one call

Weighing a 200-amp upgrade, or nervous about an aging fuse box? Call at any time of day and a staff member, never a recording, will book your free panel estimate, frequently for that very afternoon.

Panel Replacement & Upgrades

An overloaded, outdated, or recalled panel is both a safety risk and a bottleneck. We replace it with a modern breaker panel sized for how you actually use power today, cleanly labeled and installed to code, so adding a circuit later is simple instead of scary.

200-Amp Service Upgrades

Older homes often have 100-amp service that can't keep up with a heat pump, EV charger, and modern appliances. We upgrade the meter, mast, and panel to 200 amps so your home has the capacity for everything you want to add, now and later.

  • 100A to 200A
  • meter & mast
  • more capacity
  • EV & heat-pump ready

Sub-Panels & Added Circuits

Adding a garage, workshop, addition, or hot tub? A sub-panel gives you room for new circuits without maxing out the main. We install sub-panels and dedicated circuits, sized and wired right for exactly what you're powering.

  • sub-panels
  • dedicated circuits
  • garages & additions
  • hot tubs & shops

  • modern breakers

Whole-Home Surge Protection

A panel upgrade is the perfect time to add whole-home surge protection. Mounted right at the panel, it stops surges from storms and the grid before they reach your HVAC, appliances, and electronics, protecting your whole home from one point.

Kyle provided emergency holiday weekend service when our a/c was completely out with 104F "feels like" temperatures. He quickly diagnosed and fixed our system, with solutions for avoiding similar problems in the future. We are grateful to Kyle and Leonard Splaine!
Katie Kada Facebook recommendation
Couldn't have asked for better service! Leonard Splaine was timely, honest and did a wonderful job replacing our very outdated AC unit. We plan to use them again for any service or replacement in the future and we'll recommend them to our friends and family.
Emma F. Yelp review
I will definitely use this company again! Our AC went out on one of the hottest days of the year. They answered and came to the rescue! Family owned and very kind. Technician was knowledgeable and quick.
Ankur Mundra Facebook recommendation
I've used Leonard Splaine the last 5 years. They are professional, provide quality service, and answer my questions and concerns. Michael Ford came out this year to do my spring maintenance as well as eztrap installation and condenser coil cleaning. He did an excellent job.
Candace Bond Google review
They were such gentlemen and seemed to be very knowledgeable and honest. They were also very patient and took the time to answer all of our questions. I would highly recommend these guys.
Shawn R. Yelp review
A/C stopped working on the hottest day of the year, so far. They came over the same day and had it up and running in no time. The price was reasonable and the tech was great.

Good questions

Frequently asked questions about panel upgrades & repairs in Northern Virginia

The questions Northern Virginia homeowners ask us most about panel upgrades & repairs. Anything else, the phone's faster than the internet.

How do I know if I need a panel upgrade?

Signs include a fuse box, frequently tripping breakers, a 100-amp service, double-tapped breakers, a recalled panel brand, or plans to add an EV charger, heat pump, or addition. We inspect it and tell you straight whether it needs upgrading.

What is a 200-amp service upgrade?

It increases the amount of power your home can draw from the utility, from a common older 100 amps up to 200. That extra capacity is what lets you run modern appliances, a heat pump, and an EV charger without maxing out.

Do you replace old fuse boxes?

Yes. We remove outdated fuse boxes and install modern breaker panels. Beyond safety, it also makes many home insurers happier and makes adding circuits far easier.

Is the work permitted and inspected?

Yes. Panel and service upgrades are pulled on permit and inspected, which protects you and keeps everything to code. We handle the permitting as part of the job.

How much does a panel upgrade cost?

It depends on the panel size, whether it's a service upgrade, and the condition of the existing wiring, which is why we quote it after a look, not over the phone. You get a clear, itemized estimate before any work starts.
