Our Services
What Our Whole-House Rewiring Service Covers
Homes built decades ago in Lawrence, Andover, and the surrounding mill towns were often wired for a much smaller electrical load than modern families need. Knob-and-tube wiring, aluminum branch circuits, and undersized runs were fine for a few lamps and a radio, but they struggle under today's appliances, electronics, and HVAC equipment. Our team rewires these systems from the ground up so your home meets current code and handles everyday demand safely. We replace outdated or unsafe wiring with a system built for the way you live today, serving homeowners throughout the Merrimack Valley.
Whole-house rewiring and remodel wiring from our residential electrician team typically covers:
- Full home rewiring for older houses with knob-and-tube, cloth-wrapped, or aluminum wiring
- Remodel wiring for kitchen, bathroom, and basement renovations
- New circuits added for additions, finished attics, and converted garages
- Updated outlets, switches, and lighting circuits throughout the home
- Whole-house grounding and arc-fault/ground-fault protection upgrades
- Coordination with electrical panel upgrades when your service can't support new wiring
Our Process
How Our Rewiring Process Works
We walk every project through the same careful sequence, whether it's a full rewire of a 1920s colonial in Methuen or a remodel wiring job for a kitchen addition in North Andover. Here's what to expect from the first call to the final inspection.
-
Step 1: Home Wiring Assessment
We inspect your existing wiring, panel, and circuits to see what's original, what's been modified over the years, and what needs to be replaced for safe, code-compliant electrical installation.
-
Step 2: Rewiring Plan and Proposal
You get a clear, written plan covering the scope of work, timeline, and cost, including whether an electrical panel upgrade is needed to support the new wiring.
-
Step 3: Wiring Installation and Rough-In
Our electrical contractor crew runs new wiring through walls, ceilings, and crawl spaces with minimal disruption, then installs new outlets, switches, and fixtures to match your layout.
-
Step 4: Final Testing and Inspection
Every circuit is tested, the system is checked against local code, and we schedule the required inspection so you have documented proof the work was done right.
Why Homeowners Choose Us
Rewiring Done By A Trusted Local Electrical Contractor
Rewiring a home means letting a crew into every room you live in, so trust matters as much as technical skill. Amaury Castillo Electric Corp has built a reputation across Lawrence, Tewksbury, and Andover on careful work and clear communication from start to finish.
-
17 Years of Hands-On Electrical Experience
Our team has spent nearly two decades inside Merrimack Valley homes, so we recognize the wiring quirks common to older housing stock in this region before we even open a wall.
-
Licensed, Insured, and Code-Focused
Every whole-house rewiring project is handled by a licensed and insured electrician who treats code compliance as the baseline, not an afterthought.
-
Respect for Your Home and Your Schedule
We protect floors and furniture, keep work areas clean, and communicate clearly about timeline so a rewiring project never feels chaotic.
New Construction Electrical Wiring and Remodel Planning
Rewiring needs look different depending on the project. A full renovation or a new build gives us the chance to plan the entire electrical system from scratch, while a remodel often means working around existing walls and finishes.
Our new construction electrical wiring and remodel wiring services include:
- New construction electrical wiring planned alongside your builder from the framing stage
- Pre-wiring for future needs like EV chargers, generators, or solar panel systems
- Electrical service upgrades paired with rewiring when an older service can't support new circuits
- Dedicated circuits for kitchens, laundry rooms, and home offices during a remodel
- Smoke and carbon monoxide detector wiring updated to current code
- Electrical troubleshooting to track down and correct any hidden wiring issues before closing up walls
Rewiring Questions, Answered
Frequently Asked Questions About Whole-House Rewiring
How do I know if my home needs whole-house rewiring?
Warning signs include flickering lights, warm outlets, frequent breaker trips, a fuse box instead of a modern panel, or wiring insulation that looks cracked or brittle. If your home still has knob-and-tube or cloth-wrapped wiring, a full rewire is usually the safest long-term fix.
Will I need an electrical panel upgrade along with rewiring?
Often, yes. Many older homes in the Merrimack Valley were built with 60 or 100 amp service, which isn't enough once new circuits are added. We'll tell you upfront if a panel upgrade is needed so there are no surprises mid-project.
Can you rewire a home while I'm still living in it?
Yes. Most whole-house rewiring projects are done in phases, working room by room so you can stay in your home. We'll walk you through the schedule before work starts so you know what to expect each day.
How is remodel wiring different from a full rewire?
Remodel wiring updates the circuits tied to a specific renovation, like a kitchen or bathroom, while a full rewire replaces the wiring throughout the entire house. We can scope either one depending on your project and budget.

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!

Couldn’t be happier with our electric panel upgrade! From start to finish, the process was smooth and stress-free. Amaury was knowledgeable, respectful of our home, and did excellent work. Everything works perfectly and the upgrade gives us real peace of mind. I’d absolutely use them again.

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.
