 Trustindex verifies that the original source of the review is Google. The Castro team was professional, prompt and very easy to work with.  I had called for service after losing power in a portion of my home and being unable to fix myself. They came the next morning, after determining an after hours service was not necessary, and they were able to resolve the issue quickly. They very clearly answered my questions and explained what may have caused this. I would reach out to them for any electrical needs in the future

Why Burlington’s Homes and Offices Both Call Castro Electric

Burlington is an unusual mix for an electrician to serve well: quiet 1960s subdivision streets a mile from one of the busiest commercial corridors in Middlesex County. Getting both right requires different instincts: a homeowner near Simonds Park wants minimal disruption, while a tenant fit-out off Middlesex Turnpike is measured in downtime and deadlines. We staff and schedule for both:

Residential jobs are quoted around your household’s schedule; commercial jobs are quoted around your business hours, with off-hours work available when downtime isn’t an option.
We size panels and circuits for what you’re actually running, whether that’s a home office setup or a full retail lighting retrofit near Burlington Mall.
Permitting is handled the same way regardless of client size: we pull it, we coordinate the inspection, you don’t chase paperwork either way.
Our crews carry the same license and insurance (MA Master Electrician #24276-A) onto a subdivision job site as they do into an office park.
Emergency dispatch runs 24/7 for both; a tripped panel doesn’t care whether it’s in a living room or a server closet.

Common Electrical Requests We See in Burlington

Residential panel upgrades: Many Burlington homes were built during the town’s rapid growth between 1955 and 1965, and their original panels often can’t support today’s appliances, HVAC, and EV charging see our electrical panel upgrade in Burlington, MA page.
EV charger installation: With Route 128/I-95 and Route 3 running through town, Burlington homeowners and businesses are installing Level 2 chargers at a growing rate. Check out EV charger installation in Burlington, MA.
Commercial build-outs and tenant fit-outs: Burlington’s dense office park and retail corridor along Middlesex Turnpike and near Burlington Mall regularly needs lighting retrofits, panel capacity upgrades, and data cabling.
Historic home wiring: A handful of Burlington’s original homes, including properties dating back to the 1600s, still need careful, code-compliant rewiring that respects the property’s age.
Generator installations: Homeowners near Mill Pond and the town’s residential neighborhoods often add backup power for peace of mind during storm-related outages.

FAQs

Do you actually do commercial work, or is Burlington mostly a residential stop for you?

Commercial is a real part of our Burlington workload: office parks, retail near Burlington Mall, and warehouses along Route 128 keep us busy alongside residential calls. Fit-outs, lighting retrofits, panel capacity upgrades, and ongoing maintenance are all things we handle regularly.

Can you schedule commercial work around our business hours so we're not closed for it?

Yes. Off-hours and weekend scheduling is standard for tenant fit-outs and retail work where downtime has a real cost we plan around your operating hours, not ours.

What's the permit process for electrical work in Burlington?

We pull the wiring permit through the Town of Burlington Building Department and manage the inspection, for both residential and commercial jobs.

My subdivision-era home has a Federal Pacific or Zinsco panel. Worth replacing?

Yes, both are recognized fire risks that inspectors and insurers flag. We replace them with modern, code-compliant panels, typically $2,500 to $4,500 for a 100 to 200-amp upgrade.

Can you install EV charging for a home and for a commercial parking area?

Yes, both. Residential Level 2 chargers (Tesla, ChargePoint, Wallbox, etc.) and multi-unit commercial charging setups for offices near Middlesex Turnpike are both things we install regularly.
