Why Andover Trusts Castro Electric for Local Electrical Work
Andover is a town of extremes when it comes to housing age — 350-year-old colonials a few blocks from homes built last year — so we don’t run one script for every job. A tripped-breaker call gets the same urgency as a multi-week rewiring project at a Ballardvale colonial. A few things Andover clients mention most often:
- We diagnose before we quote, so a colonial with surprise wiring behind the plaster doesn’t turn into a moving target on price once the walls are open.
- Every estimate is written down before work starts — no verbal-only numbers that shift midway through.
- We plan around solar, a second EV charger, or an addition when it’s on your radar, so today’s panel work doesn’t need to be redone in three years.
- Cleanup is part of the job, not an afterthought, especially in occupied homes near Phillips Academy where families are living around the work.
- Our credentials hold up to scrutiny: MA Master Electrician License #24276-A, full liability and workers’ comp coverage and a track record Andover’s building inspectors already recognize.
Common Electrical Requests We See in Andover
- Historic home rewiring: Many Andover properties near Ballardvale, Shawsheen Village, and the town center date back to the 1800s or earlier — we regularly update knob-and-tube wiring and undersized panels while preserving the character of the home.
- Panel upgrades for growing homes: Older 60- and 100-amp panels can’t keep up with central air, home offices, and EV charging — we handle full electrical panel upgrades in Andover, MA.
- EV charger installation: With commuters using I-93 and I-495 daily, more Andover homeowners are adding Level 2 chargers — see our dedicated EV charger installation in Andover, MA page for details.
- Generator installations: Andover’s tree-lined streets and occasional storm-related outages make backup power a popular request, especially for homes near Harold Parker State Forest.
- Commercial electrical work: From retail spaces along Route 28 to offices near the Andover/Ballardvale commuter rail stations, we handle build-outs, lighting retrofits, and maintenance.

FAQs
Is Castro Electric actually licensed to work in Andover, or just nearby?
We’re a Massachusetts-licensed shop (MA Master Electrician License #24276-A) with full liability and workers’ comp coverage, and Andover has been a regular part of our service area for years, not a town we just started covering.
Andover requires a permit for most electrical work — do you handle that, or is it on me?
We pull it. Our crew submits the wiring permit to the Town of Andover Building Department and coordinates the inspection directly, so you’re not the one chasing paperwork.
My house is in Ballardvale or Shawsheen Village and probably still has knob-and-tube behind the walls somewhere. Is that a big deal?
It’s common in that part of Andover, and it’s worth addressing rather than ignoring. We replace knob-and-tube and undersized panels while working carefully around original plaster and trim, and if your panel is a Federal Pacific or Zinsco brand both known fire risks, we’ll flag that too.
Can you actually add a Level 2 EV charger without a full rewire?
Usually, yes. We install Tesla, ChargePoint, Wallbox, and most other Level 2 chargers, and only recommend a panel upgrade if your existing service genuinely can’t support it. See EV charger installation in Andover for specifics.
What happens if something goes wrong at 11pm on a Saturday?
Call 617-668-1884. We run 24/7 emergency dispatch, so a tripped main breaker or an outage near Routes 93/495 doesn’t have to wait until Monday.
Roughly what does a panel upgrade run, and does Andover qualify for any rebates?
Most 100-amp to 200-amp upgrades land between $2,500 and $4,500, and many Andover homes qualify for Mass Save rebates on the lighting or heat-pump-adjacent portion of the work; we’ll check eligibility as part of the quote.
