Electrical Panel Upgrades
Electrical Panel Upgrades in Lawrence, MA and the Merrimack Valley
Safe, code-compliant electrical panel upgrades for homes across Lawrence and the Merrimack Valley. Amaury Castillo Electric Corp replaces outdated panels with systems built for modern power needs.
What Our Electrical Panel Upgrades Include
Homes across Lawrence and the surrounding Merrimack Valley were often wired decades ago, long before central air, home offices, and electric vehicles became standard. A panel built for 60 or 100 amps simply cannot carry that load safely, especially with EV chargers, central air, and a kitchen full of appliances, which is why so many homeowners turn to us for a full electrical panel upgrade.
Our work goes beyond swapping one box for another. We evaluate your entire electrical service, from the main line down to individual circuits, and recommend the right-sized system for your household.
- 100 amp to 200 amp service upgrade installation for growing power needs
- New breaker panel installation to replace old fuse boxes or damaged panels
- Electric meter replacement coordinated with your utility provider
- Circuit additions and relabeling for accuracy and safety
- Code compliance upgrades to meet current Massachusetts electrical standards
- Panel upgrades paired with generator, EV charger, or solar installation
Our Process
How a Panel Upgrade Works From Call to Completion
Replacing an electrical panel involves more than the physical swap. Our process is built to keep your home safe, your paperwork in order, and your downtime to a minimum.
-
Step 1: Home Electrical Assessment
We inspect your current panel, wiring, and service capacity to determine whether a 100 amp or 200 amp service upgrade fits your household's actual usage and future plans.
-
Step 2: Permitting and Utility Coordination
As a licensed electrical contractor, we pull the required town permits and coordinate with your utility company on any electric meter replacement or service line changes.
-
Step 3: Panel Installation and Electrical Service Upgrades
Our team shuts off power safely, removes the old panel, and installs the new breaker panel along with any related electrical service upgrades your home needs.
-
Step 4: Testing and Final Inspection
Once the new panel is in place, we test every circuit, confirm proper grounding, and schedule the town inspection so your upgrade is fully documented and code-compliant.
Why Homeowners Choose Us
Benefits of Upgrading Your Electrical Panel
A panel upgrade is not just about avoiding tripped breakers. It protects your home, supports the technology you rely on, and adds real value when it comes time to sell.
-
Experienced Residential Electrician
With 17 years in the trade, Amaury Castillo brings hands-on experience to every job, so your residential electrician gets the upgrade right the first time, without guesswork.
-
Safer, More Reliable Power
Old panels are a leading cause of electrical fires and nuisance outages. A modern panel reduces that risk and keeps power flowing steadily to every room.
-
Ready for What You Add Next
Whether you are planning a generator, an EV charger, or a kitchen remodel, a properly sized panel means future electrical installation projects go smoothly instead of hitting capacity limits.
Our Services
Signs Your Home Needs a 200 Amp Service Upgrade
Many homeowners do not think about their panel until something stops working. Watch for these warning signs that your current service is falling behind:
- Breakers trip repeatedly, especially when running multiple appliances
- Lights dim or flicker when the AC or a large appliance kicks on
- Your panel still uses fuses instead of breakers, or shows rust and scorch marks
- You are adding a hot tub, EV charger, home generator, or solar panels
- Your home was built before 1990 and has never had an electrical service upgrade
- A home inspector or insurance company flagged your panel as outdated
If any of this sounds familiar, our team can inspect your panel and walk you through straightforward, honest pricing before any work begins. We also handle the electrical repair and troubleshooting that often comes up during an inspection, so small issues get fixed alongside the upgrade rather than left for later.
Panel Upgrade Questions
Frequently Asked Questions About Electrical Panel Upgrades
How do I know if I need a 200 amp service upgrade?
If your home regularly trips breakers, you are adding major appliances, an EV charger, or a generator, or your panel is more than 25 years old, a 200 amp service upgrade is usually worth the investment. We can assess your current load and tell you plainly whether an upgrade makes sense for your situation.
Will I need an electric meter replacement during the upgrade?
Sometimes. If your new panel requires a different service size or your current meter equipment is outdated, we coordinate electric meter replacement directly with your utility provider so there is minimal gap in service.
How long does an electrical panel upgrade take?
Most residential panel upgrades are completed in a single day, including the permit inspection scheduling. Larger projects involving a full service upgrade or meter work may take slightly longer, and we will give you a clear timeline before starting.
Do you handle the permits for electrical service upgrades?
Yes. As a licensed electrical contractor, we pull all required town permits, schedule inspections, and make sure the finished work meets Massachusetts electrical code, so you never have to manage the paperwork yourself.

Mr. Castillo was prompt for the scheduled appointment, he came equipped with his tools/van/uniform. He went to work immediately, friendly, knew where to trouble shoot the electrical problem, corrected the problem within one hour of arrival while running down to the basement and up to the second floor bedroom several times where my daughters lights had gone out. I recommend this electrical expert to repair your electrical issues and he can also communicate in spanish , I give this company five stars *****!

I recently had several electrical issues at my home and was fortunate to find Amubury. He arrived promptly and was able to accurately diagnose the problems within minutes. I was incredibly impressed that he was able to fix everything in just a couple of hours. He even took the initiative to run out and purchase a necessary replacement part himself, which kept the process moving efficiently without any delays. Throughout the entire experience, Amubury was professional, courteous, and highly efficient. What stood out most was how thorough he was—he took the time to clearly explain the issues and walked me through the solutions, making sure all of my questions were answered. His pricing was very reasonable given the high quality and speed of his work. I was genuinely impressed and would highly recommend his services to anyone in the area. I will certainly be calling him again for any future electrical needs!

I was lucky enough to meet Amaury when I moved into my “new” home almost 10 years ago and he has been my go- to for everything electrical since! From installing a new fan on a cathedral ceiling to recessed and living room spotlights to changing out fan switches in bathrooms - he has done it all. Fast, responsive, fair and courteous- I really can’t say enough about Amaury, he truly is the BEST. Thanks Amaury!

We lucked out when I found Amaury on Angie's List years ago. Since then, he's fixed issues that have cropped up, installed a generator hook-up, and then replaced our entire (very old) electrical panel. He's responsive, thorough, knowledgable, insightful, voluntarily explains things and is fairly priced. Cannot recommend him enough!

Amaury quickly came over to check over the electrical wiring for our generator and electrical box, making a couple of thoughtful suggestions and quickly ensuring that we had heat in the event of a power outage in the Jan '26 snowstorm. Would recommend Amaury for any number of electrical work.

Amaury was super knowledgeable, efficient (he didn’t waste time), and I appreciate that he was conscious of the neat and clean look of the job putting in some complicated ceiling lighting. He asked me my opinion along the way so as to get just what I wanted while completing the job. And he left no mess behind. Thank you Amaury- first time using your service. Looking forward to having you as a reliable electrician for future jobs.
