Looking for an electrician in Nashua, NH? WJW Electric is based in Pepperell, Massachusetts, and Billy Webber holds a New Hampshire master electrician license alongside his Massachusetts one — which is what it takes to pull a permit and do the work legally in Nashua.
Nashua is New Hampshire’s second-largest city and by far the most varied housing market we work in. Roughly 91,000 people, close to 37,000 housing units, and a building history that runs from 1820s mill construction straight through to new build. What that means practically: no two Nashua electrical jobs look alike.
Nashua’s Older Housing Is the Real Story
About one in five Nashua homes was built before 1940 — and in the downtown neighborhoods, closer to one in three. That is a far higher concentration of genuinely old housing than any of the surrounding towns, and it is why knob-and-tube removal, rewiring, and service upgrades make up so much of our Nashua work.
Nashua grew as a mill city. The Nashua Manufacturing Company began building in the Millyard in the 1820s, and the housing that went up around it — the multi-families, the workers’ housing, the neighborhoods stacked around downtown — is still standing and still occupied. Beautiful, sturdy, and wired for a world with a few light bulbs and not much else.
Those houses are where we find knob-and-tube wiring in the attic, cloth-covered conductors, two-prong outlets throughout, and fuse boxes that insurance carriers are no longer comfortable with. Sometimes it’s a targeted replacement; sometimes it’s a whole-house rewire. Almost always it’s paired with an electrical service upgrade, because the old panel can’t carry properly grounded modern circuits.
Out in the newer parts of the city — the postwar neighborhoods and the 1970s-through-90s subdivisions on the north and south sides — the wiring is generally fine. Those homes need capacity instead: EV chargers, hot tubs, heat pumps, finished basements.
Multi-Family and Converted Homes
Something that sets Nashua apart from every other town we serve: only about 45 percent of the housing stock is detached single-family. The rest is apartments, duplexes, and houses converted into two- and three-family homes — roughly a sixth of the city’s housing is in that converted or small multi-family category.
Those buildings bring their own electrical problems. Services that were split when the house was divided and never properly upsized. Metering that doesn’t match how the units are actually used. Decades of alterations layered on top of original wiring, often by whoever was cheapest at the time. Shared basements where nobody is certain which panel feeds what.
If you own a two-family in Nashua, or you’re buying one and the inspection turned up questions about the electrical, that’s work we know well.

Getting Around Nashua
We come up from Pepperell either through Hollis on Route 130 or via the Route 3 corridor, and we work across the whole city — downtown and the Main Street area, the neighborhoods around Mine Falls Park and the Nashua River, the north end out toward Amherst Street, and the south side down toward the Hudson line.
The practical difference in a city like Nashua is access and age. Tight lots, shared driveways, finished basements, and service entrances that were installed before anyone imagined what a house would need to run. A lot of the job is figuring out what previous decades left behind before adding anything new.
Permits & Inspections in Nashua
Electrical work in Nashua is permitted and inspected by the city, and it must be performed by a licensed New Hampshire electrician. Because Nashua is close to the state line, plenty of homeowners here reach out to Massachusetts contractors first — and a Massachusetts license, however good the electrician, doesn’t allow them to pull a permit in Nashua.
Billy holds New Hampshire master electrician license #16011 alongside his Massachusetts master license. We pull the permit and coordinate the inspection ourselves.
This comes up constantly in older Nashua homes at resale. Unpermitted panel or rewiring work discovered during a buyer’s inspection can stall a closing outright.

Nashua Electrician FAQs
Do I need a licensed New Hampshire electrician in Nashua?
Yes. Electrical work in Nashua requires a licensed New Hampshire electrician and is inspected by the city. A Massachusetts license alone isn’t sufficient — which matters here, because Nashua is close enough to the border that many homeowners call MA contractors first.
Is knob-and-tube wiring common in Nashua?
More common than in the surrounding towns. Roughly a fifth of Nashua homes were built before 1940, and downtown that figure is closer to a third. Those older multi-family and mill-era homes are where knob-and-tube, ungrounded circuits, and long-outdated panels still turn up.
Do you work on multi-family and two-family homes in Nashua?
Yes. Nashua has a large stock of duplexes and converted multi-families, and they bring their own issues — shared or undersized services, separate metering, and decades of alterations layered on original wiring. That’s normal work for us.
Can you upgrade the electrical service in an older Nashua home?
Yes, and it’s one of the most common jobs we do in the city. Many older Nashua homes still run on 100-amp service or an original fuse box that can’t support modern demand. We run a load calculation first and tell you what the house actually needs.
How long does it take you to get to Nashua from Pepperell?
It’s a short drive — either up through Hollis on Route 130 or via the Route 3 corridor. Nashua is one of the larger markets we serve and we’re in the city regularly.
