Kitchen Remodel Electrical
A kitchen remodel almost always means more demand on your electrical system. New appliances, an island with outlets, updated lighting layouts, dedicated circuits for high-draw equipment — it adds up fast, and the code requirements around kitchen electrical are specific for good reason.
We handle the full scope:
- Dedicated appliance circuits for refrigerators, dishwashers, microwaves, and ranges
- Island and countertop outlets placed to code and positioned for how you actually use the space
- Lighting layout and installation including recessed, under-cabinet, and fixture wiring
- Circuit upgrades where the existing panel can’t support the new load

Basement Wiring & Finishing in Newton Homes
Finishing a basement is one of the highest-return projects a Newton homeowner can take on. Getting the electrical right from the start means no rework later, and no surprises when the inspector shows up.
We wire finished basements from scratch, including:
- Full lighting and outlet installation laid out for livable, functional space
- Dedicated circuits for home offices, gyms, media rooms, or wet bars
- Moisture and safety considerations specific to below-grade environments
- Egress and code compliance so the space passes inspection the first time
Electrical for Home Additions & Expansions
Adding square footage means adding electrical capacity. New rooms need circuits, lighting, outlets, and proper integration with your existing system — and depending on the size of the addition, your panel may need to grow with it.
We assess your current capacity before we start, plan the new circuits around how the space will actually be used, and make sure everything ties in cleanly without overloading what’s already there.
Stop Peering Through The Blinds
We know waiting on a contractor is its own kind of stress. So we built a system to eliminate it entirely.
Booking Confirmation SMS
The moment your appointment is confirmed, you’ll get a text with all the details, including your tech’s name, your scheduled time window, and a link to manage your booking.
Meet Your Tech
Before your technician arrives, you’ll receive a personalized introduction, including their name, photo, and their information. You’ll know exactly who to expect at your door before they ring the bell.
“On My Way” Live Tracking Link
When your tech is en route, you get a live tracking link so you can see exactly where they are and how far out they are. Real-time visibility from the start.
New Construction Electrical in Newton, MA
New construction gives you a clean slate, and that’s worth doing right. We design and install complete electrical systems from the ground up, working closely with your contractor and builder to make sure the rough-in, service, panel, and finish work all land on schedule.
Planning ahead pays off here. We help you think through load capacity, future-proofing for EV chargers or smart home systems, and code compliance from day one so there are no surprises at inspection.
Do You Need a Panel Upgrade for Your Renovation?
Significant renovations frequently reveal that the existing panel wasn’t built for modern demand. If you’re adding circuits, new appliances, or substantial square footage, it’s worth having us assess your panel capacity before the project starts rather than after. Visit our Panel Upgrades page to learn more.
FAQs about Home Renovation Electrical Services
In most cases, yes. Any new circuits, panel work, or significant wiring changes require a permit in Massachusetts. Castle Electric handles the permitting process and makes sure all work is inspected and up to code before we call the job done.
That’s one of the first things we assess. If your panel is undersized for the new load, we’ll let you know before the project starts, not after.
Yes. We coordinate directly with your contractor, builder, and other trades to make sure the electrical work fits into the overall project timeline.
We’ll tell you exactly what we found and give you options. Older Newton homes frequently have knob and tube or cloth wiring that’s past its safe service life. Addressing it during a renovation is almost always easier and more cost-effective than doing it separately.
Yes. We handle the full scope from rough-in through finish, including fixture installation, device installation, and final inspection.
The earlier the better, particularly for larger projects. Reaching out before demo begins gives us time to plan the electrical scope alongside the rest of the project rather than reacting to it.
Not if we can help it. We’re used to working within contractor schedules and showing up when we’re needed so we don’t become the bottleneck.
Real Homes. Real Upgrades.
