We service this area because we know the neighborhoods and the wiring in them. DeFilippo Electric has been the go-to choice for homeowners, landlords, and business owners across North Haven and the surrounding South Central Connecticut region since 2014. When you call, you reach someone local who knows the area, understands the housing stock, and can get a licensed electrician to your door fast. Same-day service is available, and we are ready to help whether you have a tripping breaker, a panel that needs replacing, or a full rewiring project on your hands.
We answer when you call. We arrive when we say. We leave it safe.
Keeping a home safe starts with the wiring behind the walls, and the same holds true for any commercial space. We work with homeowners, renters, property managers, and business owners across North Haven and the broader South Central Connecticut region. Whether the job is a single outlet repair or a full commercial panel upgrade, our approach stays the same: show up on time, do the work right, and make sure every circuit leaves the property in safe, code-compliant condition.
Dependable service. Honest rates. Local know-how.
Residential electrical work covers more ground than most people realize. We handle:
If something feels off with your home's electrical system, it is worth a call. Small problems have a way of becoming bigger ones.
Property managers, office tenants, retail spaces, and restaurants all have electrical needs that go beyond the typical residential call. We handle commercial electrical repairs, panel upgrades, branch circuit wiring, and lighting installation for a wide range of commercial spaces. Work performed by licensed electricians means the job meets code the first time, which matters when you are managing a property or running a business that cannot afford extended downtime.
DeFilippo Electric was founded in 2014 by a North Haven native who spent years working for other electrical contractors before deciding it was time to build something closer to home. The goal from the start was straightforward: hire skilled people, treat customers honestly, and do work that holds up. Twelve years later, that has not changed.
Working in this part of Connecticut means knowing the housing stock well. A lot of homes in North Haven and the surrounding towns were built in the mid-twentieth century, and older wiring, whether knob-and-tube, aluminum branch circuit wiring, or undersized panels from a different era, is still common. We have seen it all, and we know how to bring older systems up to where they need to be safely and correctly. As locally owned and operated electricians, we take that responsibility seriously.
Your panel is in good hands with us.
Before a small wiring issue turns into a hazard, it is worth having someone take a proper look. A flickering light might be a loose connection. A breaker that keeps tripping might be a sign of a circuit that is overloaded or a device that is drawing too much current. A dead outlet could be a tripped GFCI somewhere else in the circuit, or it could point to something more serious in the panel.
When we come out for a diagnostic visit, we trace the problem from the symptom back to the source. We test circuits, check connections, inspect the panel, and find the root cause rather than patching over it. We keep you informed from diagnosis to final test, so you always know what we found, what we are doing about it, and what it will cost before any work begins.
Many homes in the North Haven area are still running on panels that were installed decades ago. A 100-amp service was standard for a long time, but modern households use far more power than those older systems were designed to handle. If you are adding an EV charger, a home addition, or major appliances, your panel may not have the capacity to support it safely.
We handle breaker panel replacements, 200-amp service upgrades, subpanel installation, service-entrance upgrades, and load calculations for properties that are growing or changing. Code-compliant wiring on every job means the upgrade is done to current standards, which protects your home and keeps your insurance and inspection records clean. Let us handle the panel and the permits.
Doing electrical work right matters, and we will help you get it right, whether the job is a single dimmer switch or a whole-home rewiring project. We install outlets of all types, including GFCI, AFCI, USB, and standard 15- and 20-amp configurations. We handle dimmer switches, light switch repairs, recessed lighting, LED retrofits, and indoor and outdoor fixture installation. Ceiling fans, under-cabinet lighting, and landscape lighting all fall within our scope.
For older homes in Connecticut, wiring replacement is one of the most important upgrades a homeowner can make. Knob-and-tube wiring was not designed for the loads modern homes place on their circuits, and aluminum branch circuit wiring from the 1960s and 70s comes with its own set of safety concerns. We replace old wiring with modern copper wiring to current code, and we do it in a way that minimizes disruption to your home. We will get your lights back on fast.
Here is what most people get wrong about their wiring: they assume a standard outlet is enough for a major new load. It rarely is.
EV Charger Installation. A Level 2 home charger requires a dedicated 240-volt circuit sized for the charger and the vehicle. Connecticut has seen consistent growth in EV adoption, and we install EV charger circuits for homeowners and property managers who want to charge overnight without straining an existing circuit.
Backup Generator Hookup. Storm-related outages are a real concern in this part of New England. A properly installed transfer switch keeps your generator safely isolated from the utility line, protects the equipment, and keeps your home running during an outage. We install generator transfer switches and connect standby and portable generators to your home's electrical system.
Whole-Home Surge Protection. A single power surge can damage electronics, appliances, and HVAC equipment throughout a home. Whole-home surge protection installs at the panel and catches surges before they reach your devices. It is one of the most cost-effective electrical upgrades available, and we install it on new panel jobs and as a standalone addition.
Give us a ring and consider it handled.
Pricing surprises are one of the most common complaints people have about home service work. We do not operate that way. Before any work begins, we explain what we found, what needs to be done, and what it will cost. If the scope changes once we are into the job, we stop and talk to you before moving forward.
Same-day electrical service is available for customers who need a fast response, and we work to keep scheduling flexible for jobs that cannot wait. Call for a quote and we will walk you through the process, answer your questions, and get you on the schedule.
Not the biggest crew in town. Just the most reliable. Always on time.
A home electrical inspection is a practical tool for homebuyers, landlords, and homeowners planning a renovation. We check the panel, review the branch circuits, test outlets for proper grounding and GFCI protection, look for AFCI coverage in required areas, and flag any code issues that need attention. If you are buying a home and want to know what you are getting into before closing, or if you are a landlord preparing a unit for a new tenant, an inspection gives you a clear picture of where things stand.
We also check arc-fault and ground-fault protection, smoke detector wiring, and any visible signs of old or deteriorated wiring. The report you get is plain-language and actionable.
We are based in North Haven and serve communities throughout the South Central Connecticut region. Our service area includes:

| Electrical Service | What's Included | Common Situations | Worth Knowing |
|---|---|---|---|
| Electrical Panel & Service UpgradesMost Popular |
| homes with an undersized or aging panel, or any property adding significant new load | We pull the permits, coordinate the inspection, and make sure the work meets current code before we leave. |
| EV Charger Installation |
| EV owners who want faster home charging and a safe, code-compliant installation | Connecticut has one of the highest EV adoption rates in the country; we handle the panel review and circuit in a single visit when capacity allows. |
| Ceiling Fan Installation |
| homeowners replacing a light fixture with a fan, especially in older homes | Many older ceiling boxes are not rated to support a fan's weight and movement; we check and replace as needed. |
| Dedicated Appliance Circuits |
| homeowners adding a major appliance or finishing a basement or workshop space | A dedicated circuit prevents nuisance tripping and protects the appliance from shared-load fluctuations. |
| Backup Generator Installation |
| homeowners who lose power regularly during Nor'easters and ice storms | We handle the electrical connection and transfer switch; we do not sell or service the generator unit itself, but we coordinate with your supplier. |
| Wiring & Circuit Installation |
| remodels, additions, or any project that requires new or extended circuits | All wiring is installed to current code, and permits are pulled when the scope requires them. |
| Outlet & Switch Installation |
| homeowners adding convenience, updating older outlets, or meeting code requirements | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor areas on most homes. |
| Basement & Sump-Pump Circuits |
| homeowners finishing a basement or adding reliable power for a sump pump | A dedicated circuit for a sump pump ensures it has the power it needs when water is rising, without sharing load with other devices. |
| Electrical Safety Inspections |
| buyers, sellers, and owners of older properties or homes undergoing renovation | An inspection covers the panel, visible wiring, outlets, grounding, and any components showing signs of wear or code issues. |
| Electrical Repairs & Troubleshooting |
| homeowners and tenants with an active electrical problem | Repeated tripping or warm outlets are warning signs worth addressing quickly, not later. |
| Lighting Installation |
| renovations, new construction, and homeowners upgrading to energy-efficient fixtures | Connecticut winters are hard on outdoor fixtures; we use mounting methods and materials rated for the exposure. |
| Code-Correction Wiring |
| property owners who have received a code violation notice or failed an electrical inspection | We assess the scope honestly, explain the corrections needed, and complete the work so the inspection can close. |
| Knob-and-Tube & Aluminum Rewiring |
| owners of pre-1980 homes in North Haven and surrounding towns with original wiring still in place | Many insurers flag knob-and-tube wiring as a condition for coverage; addressing it removes both the safety concern and the insurance issue. |
| Breaker & Fuse Repair |
| homes where a single breaker or fuse is the source of the problem | A breaker that trips under normal load may indicate an overloaded circuit or a failing breaker, not just a nuisance. |
| Whole-Home Surge Protection |
| homeowners with sensitive electronics, smart-home equipment, or recently upgraded panels | A single surge event can damage wiring and appliances throughout the house; a hard-wired protector at the panel defends every circuit at once. |
What are the signs that my electrical panel needs to be upgraded?
Breakers that trip under normal household loads, a fuse box that has not been updated in decades, lights that dim when an appliance kicks on, and a panel that feels warm to the touch are all signs worth a closer look. Homes adding an EV charger, a large appliance, or a finished basement often find that the existing service simply does not have enough capacity. We walk through a plain-language load calculation so you understand exactly what an upgrade covers and why it matters before any work begins.
Why does my breaker keep tripping?
A breaker that trips repeatedly is telling you something is wrong on that circuit. The most common causes are an overloaded circuit carrying more load than it was designed for, a short circuit in a device or in the wiring itself, or a failing breaker that can no longer handle its rated load. Resetting it without finding the cause can damage wiring and connected equipment over time. We trace the circuit, identify the root cause, and fix it correctly rather than leaving you in a reset loop.
Is electrical work in North Haven permitted and inspected?
Most electrical work beyond basic device replacement requires a permit and a final inspection by the local authority. We pull the permits, schedule the inspection, and make sure everything meets current code before we consider the job complete. Code-compliant wiring on every job is not a talking point for us; it is just how the work gets done.
Same-Day Service Available
When an electrical problem cannot wait, we offer same-day service for urgent calls throughout North Haven and the surrounding area. Call us early and we will do our best to get out the same day.
How do I know if my older home needs rewiring?
Homes built before the mid-1950s may still have knob-and-tube wiring, and homes built through the 1970s may have aluminum branch circuits. Both systems have limitations that modern loads expose quickly. Warning signs include outlets with no ground slot, breakers that trip under light loads, and wiring that insurers flag as a condition for coverage. We assess what is in place honestly, explain your options for whole-home or partial rewiring, and give you a clear picture of what the project involves before any work begins.
What does EV charger installation involve?
A Level 2 home charger runs on a 240-volt dedicated circuit, which means your panel needs to have the capacity to support it. We start with a panel review, run the dedicated circuit, and install the charger outlet or hardwired connection. We work with all major EV brands, including those using standard J1772 connectors. If a panel upgrade is needed first, we walk you through that as part of the same conversation so you have a complete picture of the project.
Do I need to be home when the electrician comes out?
For most jobs, yes. We need access to the panel, the affected circuits, and the areas where work is being done. For a diagnostic visit, your presence also helps because you can show us exactly what you have noticed and walk us through any recent changes in the home. We confirm the appointment in advance and work to keep scheduling flexible so the visit fits your availability.
Work Performed by Licensed Electricians
Every job, from a single outlet repair to a full panel upgrade, is handled by licensed electricians who take the time to do the work right. We keep you informed from diagnosis to final test.
How does pricing and estimating work?
We give you a clear explanation of what the work involves and what it will cost before any work begins. If we find something unexpected once we are into the job, we stop and walk you through it before moving forward. You will not receive a surprise invoice at the end of a visit.
Are you available for same-day or after-hours electrical calls?
Same-day electrical service is available for urgent situations. We are available every day from 6:00 AM to 10:30 PM, including weekends. If you have an urgent electrical issue outside of standard business hours, call us and we will work to get someone out to you.
Experienced With Older and Newer Homes
A significant portion of the homes in this area were built in the mid-twentieth century, and we work with knob-and-tube wiring, aluminum branch circuits, and undersized panels regularly. We know what to look for and how to explain what we find.
What does a backup generator hookup actually include?
We handle the electrical side of generator installations: transfer switch installation, generator hookup wiring, and the load evaluation that determines which circuits the generator will feed. We install both manual and automatic transfer switches depending on your needs. We do not sell or service the generator unit itself, but we work alongside your supplier or installer to make sure the electrical connection is done correctly and to code. We also walk you through how the transfer switch operates so you are prepared when the power goes out.
What does whole-home surge protection actually do?
A hard-wired surge protector installed at the panel intercepts voltage spikes before they reach any circuit in the house. That covers appliances, HVAC equipment, smart-home devices, and electronics all at once, rather than relying on individual power strips at each outlet. A single surge event can damage wiring and equipment throughout the house; panel-level protection is the most complete defense available.
How long does a panel upgrade typically take?
Most panel upgrades are completed in a single day. The timeline depends on the scope of the work, whether a service entrance upgrade is involved, and the utility's schedule for reconnecting the meter. We give you a realistic timeframe upfront, keep you informed throughout the job, and do a final walkthrough when the work is complete so you know exactly what was installed and why.
Every electrical job is different, and the table above is a starting point, not the whole story. Call us at (475) 366-2995 and we will give you a straight answer about what your home or property actually needs.
