Regan Electric has been the electrician Portsmouth homeowners, landlords, and businesses call first since 1949. For more than 75 years, we have handled everything from a single dead outlet to full commercial electrical installations across Portsmouth and the surrounding Rockingham County communities. Whether you need a same-day repair or a planned upgrade, we show up, we do the work right, and we keep your property safe. Schedule it. We wire it. You're powered.
We're proud to be the local electricians this community calls first. When you reach us, you reach someone who knows Portsmouth, knows the housing stock here, and knows what it takes to get the job done without cutting corners. That kind of accountability is what makes us a local electrician homeowners rely on.
A properly wired home is a safer home, and the same holds true for every commercial property we service. From a straightforward breaker repair to a full electrical installation for a new build, we cover the complete range of residential and commercial electrical work. All work is performed by licensed electricians who follow current code requirements, including GFCI and AFCI protection where required. We handle troubleshooting and diagnostics, code-compliant wiring, outlet and switch work, panel upgrades, lighting, and more. Here is a closer look at what we do every day.
Flickering lights, a dead outlet, a breaker that keeps tripping, a switch that stopped responding. These are the calls we get most often, and they are exactly the kind of problem that deserves a prompt, professional answer. Some wiring issues are minor. Others point to something that needs attention before it becomes a bigger problem. We diagnose the cause, not just the symptom, and we fix it correctly. We offer prompt response, even for last-minute electrical calls, so you are not left waiting when something stops working. We'll take care of the circuits from here.
A dead outlet is more than an inconvenience. It can signal a wiring fault, a tripped GFCI, or a circuit that has reached capacity. We repair dead outlets, install GFCI and AFCI outlets in kitchens, bathrooms, and garages, add USB outlets where you need them, and replace worn or outdated switches throughout the home. We also install outdoor and weatherproof outlets for decks, garages, and exterior walls. Whatever the outlet or switch job looks like, we'll sort the wiring and clean up after.
From older homes to new commercial builds, lighting is one of the most visible upgrades you can make to a space. We install recessed lighting, pendant and chandelier fixtures, under-cabinet lighting, and outdoor security and motion sensor lights. We also handle landscape lighting and any exterior fixture work your property needs. Ceiling fan installation and replacement is a regular part of our work, including new wiring runs where no existing box is in place. We send experienced electricians who respect your home, and we leave the space clean when the job is done. We'll have your outlets working again in no time.
Most homeowners can't tell a minor wiring issue from a serious one, and that is especially true when it comes to the bigger electrical systems behind the walls and inside the panel. From aging wiring in older homes to capacity needs driven by modern appliances and EV chargers, we handle the work that keeps your electrical system safe and up to the load you are placing on it. This section covers our panel, rewiring, and dedicated circuit services.
A panel that trips repeatedly, runs hot, or simply cannot keep up with your home's demand is a safety concern and a daily frustration. We repair and replace circuit breakers, handle main panel replacements, and install 200-amp panel upgrades and subpanels when your service needs more capacity. Service-entrance and meter upgrades are part of this work when the utility connection itself needs attention. A panel that is sized right and wired correctly is the foundation everything else depends on. We make the fix and leave it tidy.
Portsmouth has a lot of older housing stock, and many of those homes still carry knob-and-tube wiring, aluminum branch circuits, or wiring that was installed decades before modern load demands existed. We handle whole-house rewiring, targeted rewiring for renovations and additions, and remediation of aluminum wiring and outdated systems. If you are buying an older home, remodeling, or adding square footage, we can assess what needs to be replaced and do the work properly. That is the wiring done right the first time, not a patch that creates problems later. We'll sort the wiring and clean up after.
Major appliances need their own circuits. A shared circuit for an electric dryer, a kitchen range, or a large refrigerator is a recipe for nuisance trips and, in some cases, real hazards. We install dedicated circuits and 240-volt outlets for dryers, ranges, ovens, and other high-draw appliances. If you are adding an appliance or moving one to a new location, we run the circuit and install the correct outlet for the load. We'll have your outlets working again in no time.
Coastal New Hampshire winters are hard on homes and hard on electrical systems. Nor'easters knock out power for days at a time. Sub-freezing temperatures push heating loads to the edge of what older panels can handle. Ice dams and frozen pipes are a routine winter concern for homeowners across Portsmouth and Rockingham County. The three services below address those realities directly.
When a winter storm takes out the grid, a properly installed backup generator keeps your heat running, your refrigerator cold, and your home protected. We handle the full electrical side of generator installation: the transfer switch, the wiring, the dedicated circuit, and the connection to your panel. Whether you are installing a standby generator that starts automatically or setting up a hookup for a portable unit, we do the work to code so the system is safe and ready when you need it. We'll take care of the circuits from here.
Portsmouth's older homes were not wired for today's electrical demands. Add an EV charger, a modern heating system, updated kitchen appliances, and a home office, and a 100-amp panel runs out of room fast. A 200-amp service upgrade gives you the capacity to run your home the way you actually live in it. We perform load calculations, handle service-entrance work, and coordinate with the utility so the upgrade goes smoothly from start to finish. We make the fix and leave it tidy.
Heat tape protects roof edges, exposed pipes, and exterior surfaces from ice damage during New Hampshire winters. The electrical side of a heat tape installation matters as much as the tape itself. We run the dedicated circuit, install the correct outlet or connection point, and wire the system so it operates safely without overloading your panel. This is wiring work, and we handle it the same way we handle any other circuit: carefully and to code. We'll sort the wiring and clean up after.
Demand for Level 2 home EV charger installation has grown steadily across the Seacoast region, and we handle the full electrical scope of every job. That means assessing your panel capacity, running the dedicated 240-volt circuit, and installing the charger in your garage or driveway. If your panel needs an upgrade to support the added load, we handle that too. On the protection side, whole-home surge protection installation guards your appliances, electronics, and wiring from voltage spikes that come through the utility line. Proper grounding and bonding is part of how we install every surge protection system. Good workmanship. Good pricing. Good electricians. We'll have your outlets working again in no time.
Scheduling a service call is simple, and we work hard to make sure you are not stuck waiting when something goes wrong. We offer same-day availability for repairs and urgent electrical work, and we take calls for after-hours and weekend service when the situation calls for it. If you have a dead circuit, a panel that has stopped cooperating, or a safety concern you want addressed today, call us and we will get someone out as quickly as we can. We make the fix and leave it tidy.
We work for homeowners, landlords, property managers, and businesses of every size. On the residential side, that includes everything from routine repairs in older Portsmouth homes to full electrical work for additions and renovations. On the commercial side, we handle office wiring, retail electrical installations, warehouse panel work, and electrical upgrades for businesses throughout the area. Electrical safety inspections and hardwired smoke and carbon monoxide detector installation serve both audiences well, and we schedule those jobs alongside our repair and installation work. We'll take care of the circuits from here.
A home electrical inspection gives you a clear picture of where your system stands. We check wiring, panels, outlets, grounding, and protection devices including arc-fault and ground-fault breakers, and we tell you what we find without padding the report. If hardwired smoke detectors or carbon monoxide detectors need to be installed or replaced, we handle that as part of the same visit when possible. Bathroom exhaust fan installation and other safety-related upgrades round out this part of our work. We are experienced electricians who respect your home, and we treat every inspection with the same care we bring to any installation job. We'll sort the wiring and clean up after.
Portsmouth is our home base, and we serve customers throughout Rockingham County. Our regular service area includes Exeter, Hampton, Newington, Stratham, Greenland, Rye, North Hampton, and New Castle. If you are nearby and not sure whether we cover your area, give us a call. Chances are good we have worked in your neighborhood before.
Call us at (603) 556-8248 and describe what you are dealing with. We will give you a clear estimate and get you on the schedule, including same-day appointments for most repair and service calls.
Yes. We are available for weekend and after-hours calls when the situation does not allow for waiting. If you have a tripping breaker, a dead circuit, or a safety concern on a Saturday or Sunday, call us and we will get someone out as quickly as we can.
Call us at (603) 556-8248 and tell us what you need. We will walk you through what the job involves and give you a clear estimate before any work begins, whether it is a single outlet repair or a full panel upgrade.
Our electricians introduce themselves, walk through the affected area with you, and explain what they find before starting any work. We give you a clear picture of the problem and the cost before we begin, and we clean up the work area when the job is done.
Signs worth paying attention to include flickering lights, frequently tripping breakers, burning smells near outlets or the panel, two-prong ungrounded outlets throughout the house, or a fuse box that has never been updated. Homes with knob-and-tube or aluminum branch circuit wiring benefit from a professional assessment to understand what is safe and what needs attention.
Scope and materials drive the cost more than square footage alone. A panel upgrade on a larger home with more circuits will take more time and material than a simple swap, and a rewiring project in a multi-story home costs more than the same work in a small cape. We walk through the specifics with you before the job starts so there are no surprises.
Hidden wiring conditions are the most common variable. Once we open a wall or pull a panel cover, we may find deteriorated wiring, improper previous work, or a circuit that is undersized for the load. We tell you what we find and what it will cost to address it before we proceed.
A straightforward repair like a dead outlet or a tripping breaker usually takes an hour or two. Larger jobs like a panel upgrade, a whole-home rewiring, or an EV charger installation with panel work take longer and may require a follow-up visit for inspection. We give you a realistic time estimate when we schedule the job.
Yes. Property managers and landlords with multiple units throughout Portsmouth and Rockingham County work with us regularly. We handle repair calls, safety inspections, and scheduled upgrades across properties and can coordinate access and billing to suit how you manage your portfolio.
For most jobs, yes. We need access to the panel, the affected circuits, and the work areas, and we will have questions and findings to walk through with you. If you have a specific situation where you cannot be present, call us and we will talk through what is possible.

How do I know if my home needs a panel or service upgrade?
Common signs include breakers that trip regularly under normal use, a panel that feels warm or makes buzzing sounds, a 100-amp service with a full house of modern appliances, or no room to add circuits for an EV charger or new appliance. We perform a load calculation during the estimate visit so you get a clear answer before any work begins.
What causes a breaker to trip repeatedly?
Repeated tripping usually points to one of three things: a circuit that is carrying more load than it was sized for, a failing breaker that no longer holds its rated current, or a fault in the wiring or a connected device. We trace the cause before recommending a fix, because replacing a breaker without finding the underlying issue often just delays the problem.
Is the electrical work permitted and inspected?
Work that requires a permit under the New Hampshire electrical code is pulled and inspected. Our electricians work to current code requirements on every job, including GFCI and AFCI protection where required. If you have questions about whether a specific job needs a permit, ask us when you call and we will walk you through it.
Same-Day and Emergency Availability
We offer same-day scheduling for repairs and urgent electrical work, and we take calls for after-hours and weekend service when the situation calls for it. Prompt response, even for last-minute electrical calls, is something we take seriously.
Is the wiring in my older Portsmouth home safe?
It depends on what is there and what condition it is in. Homes built before the 1970s may have knob-and-tube wiring, aluminum branch circuits, or panels that were never updated. These are not automatic emergencies, but they do warrant a professional look. We assess what is present, explain the risks honestly, and tell you what needs attention versus what can wait.
What does a home EV charger installation involve?
A Level 2 home charger requires a dedicated 240-volt circuit, typically a 50-amp run from your panel to the garage or driveway location. We assess your panel capacity first. If the panel is already near its limit, we discuss an upgrade as part of the same project. We handle the circuit, the outlet or hardwired connection, and any panel work needed to support the added load.
How does backup generator hookup work, and what do I need?
A proper generator installation includes a transfer switch, which is the device that safely connects the generator to your home's circuits and prevents back-feeding the utility line. We size the transfer switch and wiring to match your generator and the circuits you want protected. Whether you are installing a standby unit that starts automatically or a hookup for a portable generator, we handle the full electrical scope.
Experienced With Older and Newer Homes
Portsmouth's housing stock spans more than a century, and we work in all of it. Whether the home has knob-and-tube wiring or a modern panel with room to grow, our electricians know what they are looking at and how to bring the work up to current standards.
Do I need to be home when the electrician arrives?
For most jobs, yes. We need access to the panel, the affected circuits, and the work areas, and we will walk through what we find with you before starting. If your situation makes that difficult, call us and we will talk through what is workable for your specific job.
How do estimates and pricing work?
Call us and describe the job. We will talk through what is involved and give you a clear estimate before any work begins. Scope and materials drive the cost more than square footage alone. If we open a wall or a panel and find something unexpected, we tell you what it is and what it will cost to address before we proceed.
Code-Compliant Work on Every Job
Every job our electricians perform follows current New Hampshire electrical code requirements, including GFCI and AFCI protection where required and proper permitting for work that demands it. We do not cut corners on code, because the inspection is there to protect you.
What do flickering or dimming lights usually mean?
Occasional flicker when a large appliance kicks on is often a normal load response, but persistent flickering, dimming across multiple rooms, or lights that flicker without any obvious cause can point to a loose connection, an overloaded circuit, or a problem at the panel. These are worth having looked at rather than ignored, because loose connections in particular can become a fire risk over time.
Should I be concerned about warm or buzzing outlets?
Yes. A warm outlet or one that buzzes or crackles is not normal. It can indicate a loose or deteriorated connection, a circuit that is overloaded, or wiring that needs attention. Do not continue using an outlet that feels warm to the touch or makes noise. Call us and we will get someone out to take a look.
What is whole-home surge protection, and is it worth it?
A whole-home surge protector installs at the main panel and guards every circuit in the house against voltage spikes that come through the utility line. Spikes from grid switching and nearby lightning strikes can damage appliances, electronics, and even wiring over time. For a home with smart appliances, a home office, or any equipment worth protecting, it is a practical investment. We include proper grounding and bonding checks as part of every surge protection installation.
Every electrical job is different, and the best way to get an accurate answer for yours is to call us directly. We will talk through what you need, explain what the work involves, and give you a clear estimate before anything starts.
