Whether you need a quick repair, a panel upgrade, or a whole-home rewiring project, we are ready to help. Same-day electrical service is available for urgent calls, and our work is performed by licensed electricians who know what code-compliant wiring looks like from the first wire pulled to the final inspection.
We answer when you call. We arrive when we say. We leave it safe.
From troubleshooting and diagnostics to electrical safety inspections, we cover the full range of work a home or business needs. Call (475) 366-2995 to get a quote or schedule a visit.
Keeping a home safe starts with the wiring behind the walls, and most electrical problems give you a warning before they become a hazard. Flickering lights, dead outlets, a breaker that trips every time you run the microwave, a burning smell near a switch plate, a room with no power at all -- these are all signs that something needs attention.
When we come out for a diagnostic visit, we start by listening to what you have noticed, then we trace the problem back to its source. We check for arc-fault and ground-fault conditions, test GFCI and AFCI protection, and look at the panel to see whether the issue is isolated or part of a bigger capacity problem. You will know what we found and what it takes to fix it before any work begins.
Same-day electrical service is available for situations that cannot wait. We will get your lights back on fast.
An aging breaker panel is not just an inconvenience. It is a capacity problem and, in some cases, a safety risk. Panels that were installed decades ago were not sized for the electrical loads modern homes carry. If your breakers trip frequently, your panel runs warm, or you are planning to add an EV charger or major appliance, a panel upgrade is often the right first step.
We handle the full range of panel work: breaker repair and replacement, 200-amp service upgrades, service-entrance and meter upgrades, and subpanel installation for garages, workshops, and additions. Load calculations are part of every panel project so we know exactly what your home or building needs before we start.
Dedicated appliance circuits for dryers, ranges, and other high-draw equipment are often added at the same time. Let us handle the panel and the permits.
Doing electrical work right matters, and we will help you get it right, starting with the outlets and switches your household uses every day. We fix dead outlets, install new outlets in kitchens, bathrooms, garages, and workshops, and handle GFCI outlet installation and repair wherever code requires it. Need a 240-volt outlet for a dryer or range? We run the circuit and make the connection correctly.
On the switch side, we install dimmer switches, smart switches, and smart home wiring for lighting control and automation. If your switches are outdated or you are renovating a room, we can bring everything up to current standards in a single visit.
Good lighting changes how a space feels and how safe it is. We install recessed lighting, replace old fixtures with new LED options, and handle under-cabinet lighting in kitchens. Ceiling fan installation and wiring is one of our most common calls, and we handle the wiring and the mounting so the fan runs safely and quietly.
Outside, we install security lighting, motion sensor lights, and landscape lighting for walkways, driveways, and entry points. Bathroom exhaust fan wiring rounds out the list. Give us a ring and consider it handled.
Before a small wiring issue turns into a hazard, it helps to have an electrician who can look at the whole picture. We handle the project-based wiring work that comes with renovations, additions, and new construction: kitchen and bathroom remodel wiring, basement wiring, attic wiring, garage wiring, shed wiring, and workshop circuits.
Dedicated appliance circuits for washers, refrigerators, stoves, and dryers are a regular part of what we do. We also install hardwired smoke detectors and carbon monoxide detectors, which are required in most Connecticut homes and rental properties.
Whether you are building an addition in North Haven or finishing a basement in Hamden, code-compliant wiring from the start saves time and money at inspection. We service this area because we know the neighborhoods and the wiring in them.
Here is what most people get wrong about their wiring: a power strip does not protect your home from a surge. A whole-home surge protection device, installed at the panel, stops voltage spikes before they reach your appliances, electronics, and wiring. We install surge protection as a standalone upgrade or as part of a panel replacement, and we explain exactly what it covers and what it does not.
Grounding and bonding are part of every surge protection install, and we verify that your system meets current code before we leave.
Electrical safety inspections are available for homeowners, landlords, and property managers who want a clear picture of what is in their walls. We handle pre-purchase inspections, rental property inspections, and code violation repairs for homes across North Haven and the surrounding area. Work is performed by licensed electricians on every job. Your panel is in good hands with us.
North Haven and the broader South Central Connecticut area sit in some of the oldest residential neighborhoods in the country. That means knob-and-tube wiring, aluminum branch circuits, and undersized panels are not rare finds here. They are routine. Add in the nor'easters and ice storms that knock out power across the region each winter, plus one of the highest rates of EV adoption in the nation, and you have a clear picture of what local homeowners are actually dealing with.
We service this area because we know the neighborhoods and the wiring in them.
Knob-and-tube wiring was standard construction in homes built before the 1950s, and aluminum branch wiring was common through the 1970s. Both create real problems today. Knob-and-tube has no ground wire, degrades over time, and is increasingly difficult to insure. Aluminum wiring at connections and outlets is a fire risk without proper remediation. We assess what is in place, explain your options, and carry out the rewiring in stages or as a whole-home project depending on what your situation calls for. Panel upgrades and code-correction wiring are typically part of the same scope of work.
A Level 2 home EV charger runs on a dedicated 240-volt circuit and requires panel capacity to support it. We handle the full installation: load calculation, circuit run, breaker installation, and charger mounting. If your panel is already near capacity, we will tell you that before we start and walk you through the upgrade path. Connecticut has seen strong EV adoption, and we have installed chargers across North Haven, Branford, Cheshire, and nearby towns for homeowners making the switch.
When a nor'easter takes out power for two or three days, a properly wired backup generator is not a luxury. It is a practical necessity. We handle generator hookup, transfer switch installation, and standby generator wiring so your system switches over safely without backfeeding the utility line. The electrical panel work that ties it all together is part of every installation we do. Whole-home surge protection pairs well with a new generator connection, and we can handle both in the same visit.
We work for homeowners, landlords, property managers, and businesses across the region. On the residential side, that includes single-family homes, multi-family buildings, apartments, and rental properties in North Haven, Wallingford, Meriden, East Haven, North Branford, Woodbridge, and the surrounding area.
For commercial customers, we handle offices, retail spaces, restaurants, and warehouses, as well as new construction electrical work from rough-in through final inspection. Code-compliant wiring and electrical safety inspections are part of every commercial project we take on. Licensed electricians on every job, every time.
Dependable service. Honest rates. Local know-how.
When you call for a quote, we ask the right questions upfront so we can give you a clear picture of what the work involves and what it will cost. We do not believe in vague estimates that change once we are on the job. If we find something unexpected during a diagnostic, we stop and explain it before we proceed.
Same-day electrical service is available for urgent repairs. For planned projects, we work around your schedule and confirm the appointment in advance. Locally owned and operated electricians means the person who answers your call knows the area and can tell you when to expect us.
Call (475) 366-2995 to request an estimate or schedule a service visit.
A burning smell is a warning sign that should not be ignored. It can indicate overheating insulation, a loose connection arcing inside a box, or a component in the panel that is failing. Turn off the circuit if you can identify it, and call us right away. This is one of the situations where same-day service is the right call.
Knob-and-tube wiring may show signs of deterioration at insulation, lack of grounding at outlets, and an inability to support modern electrical loads. Aluminum branch wiring can cause outlets and switches to feel warm or show discoloration as connections loosen over time. Both systems warrant a proper assessment by a licensed electrician before the symptoms get worse.
The answer depends on how much of the existing wiring is problematic and what the homeowner needs the system to support. A home with knob-and-tube throughout and plans for a major renovation is typically a candidate for a full rewire. A home where only certain circuits have aluminum branch wiring may be handled with targeted remediation. We assess the scope honestly and explain the options before any work begins.
A transfer switch isolates your home's electrical system from the utility line before the generator comes online. Without it, power from the generator can backfeed into the utility line, which is dangerous for utility workers and can damage your generator when power is restored. We install both manual and automatic transfer switches and make sure the connection meets current code.
A Level 2 home charger requires a dedicated 240-volt circuit sized for the charger and the vehicle. The first step is a panel review to confirm your service has the capacity to support it. We handle the load calculation, circuit run, breaker installation, and charger mounting, and if a panel upgrade is needed first, we walk you through that as part of the same conversation.
GFCI protection is required in kitchens, bathrooms, garages, unfinished basements, and outdoor locations where water and electricity can come into contact. AFCI protection is required on most bedroom circuits and, in newer code editions, throughout much of the living space. We check existing protection during diagnostic visits and install what is needed to bring the home into compliance.
Yes. When a permit is required for the work, we pull it, schedule the inspection, and make sure everything meets current code before the inspector arrives. Code-compliant wiring on every job is not optional for us. It protects your home, your insurance, and your ability to sell the property later.
Additional charges typically come from conditions we could not see before starting the work, such as hidden wiring that needs to be rerouted, a panel that turns out to need more work than the exterior suggested, or old wiring discovered during a renovation that needs to be addressed before we can proceed safely. We stop and explain any change in scope before moving forward, so you are never surprised at the end of a job.
We start with what you have observed, then work systematically through the circuit. We test outlets, check connections at boxes and the panel, look for signs of overloading or arcing, and use diagnostic equipment to locate faults that are not visible. The goal is to find the root cause, not just the symptom.
Clear access to the panel, to any outlets or fixtures involved in the repair, and to any walls or ceilings where new wiring needs to run makes the job go faster and cleaner. If furniture is blocking the panel or a work area, moving it before we arrive saves time. We will let you know during scheduling if there is anything specific to prepare for your job.
Every circuit we work on is tested before we leave. We verify that outlets are wired correctly, breakers hold under load, GFCI and AFCI devices trip and reset as designed, and any new fixtures or connections are functioning properly. The final walkthrough is part of every job, not an optional add-on.
We avoid working on outdoor wiring during active rain or when surfaces are wet, both for safety and because wet conditions can affect connections and testing. For scheduled outdoor projects, we confirm conditions in advance and reschedule if needed. Urgent outdoor repairs are assessed on a case-by-case basis.
A switch or outlet that buzzes, feels warm, shows scorch marks, or produces a slight shock when touched is telling you there is a problem at that connection. Loose wiring inside a box can arc over time, which is a fire risk. These are not problems to put off. Call us and we will diagnose and repair the connection correctly.
Work that is not done to code or that skips steps like proper grounding, correct wire sizing, or required protection devices tends to fail earlier and can create safety hazards that are expensive to trace and correct. It can also create problems at resale when a buyer's inspector flags unpermitted or substandard work. Doing it right the first time costs less than fixing it later.
DeFilippo Electric has been serving North Haven and the surrounding Connecticut communities since 2014. We handle everything from a single dead outlet to a full-home rewiring project, and we bring the same attention to detail to every job. Repairs, panel upgrades, EV chargers, backup generators, surge protection, lighting, and wiring for renovations and new construction are all part of what we do every day.
Call (475) 366-2995 to get a quote. We keep you informed from diagnosis to final test, and we do not consider a job done until everything is safe and working.

| 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.
