Expert Electrician Services in Portsmouth, New Hampshire
Portsmouth has been a working port since 1623, and its homes carry four centuries of history — from the Jackson House of 1664 to the brick townhomes downtown. Salt air, storm surge, and nor'easters punish electrical systems here in ways inland towns never see. Electrical Service Precision Pros keeps Seacoast homes powered, dry, and up to code.

Power for the Seacoast's Oldest City
Portsmouth is New Hampshire's oldest city, settled in 1623 where the Piscataqua River meets the Atlantic. Its downtown historic district sits on the National Register, packed into a few walkable blocks. Strawbery Banke preserves the old Puddle Dock neighborhood across nearly ten acres, with buildings dating back to 1695. The Richard Jackson House of 1664 still stands as the oldest home in the state.
Four centuries of houses means four centuries of wiring problems. Colonials from the 1700s, brick townhomes from the 1800s, and salt-weathered capes all share the same enemies: time and a marine climate. Salt air corrodes outdoor electrical equipment faster than anywhere inland. Storm surge and high tides push brackish water into basements dug before electricity existed.
Eversource delivers power across the Seacoast, and nor'easters test that delivery every winter. The ice storm of December 2008 left close to 400,000 people statewide without power, the worst outage the utility had ever seen. Coastal neighborhoods here also flood when storm surge meets high tide. Electrical Service Precision Pros plans electrical work for all of it: panels above flood level, corrosion-resistant outdoor gear, generators, and whole-home surge protection.
We work in the houses other electricians tiptoe around. In the historic district, rewiring has to respect original plaster, trim, and framing — and the Historic District Commission sets rules about what can be altered. We design every job inside those rules. Walls get opened only where needed, wire gets fished wherever possible, and every surface is restored. Permits, inspections, and documentation come standard on every job.
From Market Street to the South End, from Strawbery Banke's neighbors to the suburban streets beyond, we keep Portsmouth powered. When outlets die, breakers trip, or the next nor'easter is on the forecast, call (833) 606-5080. We'll diagnose it honestly, explain your options plainly, and leave behind work built to outlast us all.

Built for the coast and its old houses
What Goes Wrong Electrically in a 400-Year-Old Port City
Salt air corrosion of outdoor electrical gear
Salt air is brutal on outdoor electrical equipment. Meter sockets, panels, AC disconnects, and exterior fixtures corrode far faster here than they do inland, and corrosion builds resistance, resistance builds heat, and heat starts fires. We replace failing outdoor gear with corrosion-resistant equipment rated for marine environments. We also seal penetrations and mount hardware to shed water. Along the Seacoast, the right outdoor equipment isn't a luxury — it's the difference between a panel that lasts and one that rots.
Basement flooding and storm surge damage
When high tide blocks the storm drains, the Piscataqua has nowhere to go but up — and into basements. Even Strawbery Banke's historic buildings take on brackish water in their cellars during bad storms. Flooded wiring, panels, and devices can't just be dried out — saltwater damage means replacement. We elevate panels above known flood levels, relocate critical equipment, and use wiring methods suited to damp locations. After a flood, we test everything before a single breaker goes back on.
Rewiring colonial-era homes under historic rules
Rewiring a house from the 1700s is nothing like wiring new construction. Original plaster, hand-hewn framing, and historic trim can't be ripped out and replaced. Portsmouth's Historic District Commission also has rules about what you can alter. We open walls surgically, fish wire through old framing, and restore every surface we disturb. The house keeps its 1790 face and gets a modern electrical system behind it, with permits and commission requirements handled as part of the job.
Nor'easter outages and restoration surges
Nor'easters and ice storms knock out power along the Seacoast, sometimes for days. Then the restoration surge fries whatever was left plugged in. The December 2008 storm is still the benchmark here — the worst outage the region had ever seen. We install generators with proper transfer switches so your heat stays on safely, never backfeeding the grid. Whole-home surge protectors at the panel handle the spike when power returns.
Undersized panels in brick townhomes
Downtown's 19th-century brick townhomes were wired for gaslight-era loads and upgraded piecemeal ever since. Many still run on panels with no room for modern life: induction ranges, heat pumps, home offices, and EV chargers. We calculate the real load and upgrade the service to match, often without disturbing the historic facade. The brick stays, the plaster stays, and the electrical system finally catches up with the century.
Ungrounded outlets and missing GFCI near water
Early wiring predates grounding, and plenty of Portsmouth homes still have ungrounded outlets in kitchens and bathrooms. Near water — sinks, tubs, and especially flood-prone basements — that's a shock hazard. We add proper grounding, install GFCI protection everywhere water is present, and give major appliances dedicated circuits. In a coastal city where water finds its way inside, this is one of the most important safety upgrades a homeowner can make.
How a Job Runs, Start to Finish
Reach out and describe it
Get in touch and tell us what's wrong in your own words — a dead outlet, a corroded panel, tripping breakers, or a project on your wish list. We'll ask a few pointed questions so our electrician arrives with the right gear. Anything sparking, smoking, or smelling hot goes straight to the front of the line.
On-site evaluation
We arrive, test the circuits in question, and open the panel to see the real story. In a historic home we also study how the structure itself is put together, so the remedy fits the building. Then comes a plain-English explanation of the issue, your options laid out, and our honest recommendation.
A plan that respects the house
Every house gets a plan that fits it. A colonial needs surgical rewiring that preserves plaster and trim. A waterfront condo needs corrosion-resistant gear. A flood-prone basement needs equipment moved above the water line. We design the work around your house, your load, and the local rules — then price it straight.
Permitted, careful work
We pull the city permits and handle Historic District Commission requirements where they apply. Then we do the work carefully: protected floors, minimal openings, fished wire wherever possible. Everything goes in to current code, labeled at the panel, and built for salt air and storms.
Testing and walkthrough
We finish by testing every circuit and device under real load. Then we walk you through the changes at the panel, so you can see exactly what feeds what. When the city requires an inspection, we set it up and meet the inspector. You get a safer house and a clear record of the work.
What to Expect Working With Us
"Our colonial predates the light bulb by a century, and the wiring proved it. They fished new wire through the old framing, barely opened the plaster, and left every room looking untouched. The inspector praised the panel work. It feels like a new house wearing an old house's clothes."
"Salt air had eaten our outdoor disconnect and half the exterior fixtures. They replaced everything with marine-rated gear and sealed it all properly. Two nor'easters since, and everything still looks brand new. Should have called them years ago."
"Our basement takes water in big storms, and the old panel sat right in the flood zone. They moved the panel upstairs, elevated everything critical, and added GFCI protection throughout. Last storm the basement got wet and the power stayed on. That panel move was the smartest money we have spent on this old house."
Serving Portsmouth and the Seacoast
Our home port is Portsmouth, and we work the whole city, from Strawbery Banke and the downtown historic district to the South End and the neighborhoods along the Piscataqua daily. The brick townhomes near Market Street, the South End colonials, and the salt-weathered capes farther out all receive the same careful treatment from our experienced crews on every single visit. We also serve the nearby Seacoast towns, including Rye, New Castle, Newington, Greenland, and Kittery just across the bridge, where coastal homes face the same salt and storms here year-round. Eversource wires the Seacoast and nor'easters test it every single year, so this team keeps its promises to you: on time, every time, guaranteed in writing, no exceptions ever, period. Corroding panel, wet basement, or plans for a generator or charger — call (833) 606-5080 and we'll roll a truck out fast and get the job done right, guaranteed today, period.
