Wiring & Rewiring for Harpswell Homeowners
New Circuit Installation
Whole-Home Rewiring
Knob & Tube Replacement
Aces Highlands handles wiring & rewiring for homeowners throughout Harpswell. We work out of 508 Riverside St Unit 1 in Portland, a short drive into Cumberland County, so response times stay quick and every job benefits from knowing the local housing stock and code requirements.
Whether you need a single new circuit or a complete rewire of an older home, Aces Highlands handles residential wiring with precision and code compliance.
Older homes in the Portland area may still have knob-and-tube or aluminum wiring that presents safety risks and insurance issues. We replace outdated wiring with modern copper wiring, properly routed and protected in every wall and ceiling cavity. A rewire often pairs with a panel upgrade for a fully modernized electrical system.
For renovations and additions, we run new circuits, install junction boxes, and ensure proper wire sizing for the intended load. We also handle plumbing and HVAC work for remodel projects, keeping everything under one roof.
Every wiring job includes proper circuit labeling, secure connections, and thorough testing. We pull permits when required and schedule inspections to ensure full code compliance.

- Based just outside Harpswell and out on Cumberland County calls every day
- No scare tactics — just an accurate diagnosis and a price that holds

Harpswell Homes and What They Need
Harpswell's housing is almost all detached houses, over 90 percent in Census estimates, spread along Harpswell Neck and Orr's, Bailey and Great Island. Of roughly 4,300 homes, about a third are seasonal, many of them old summer cottages on the water. The median build year is 1979; about one in five homes predates 1940, and roughly half predate 1980, while under a fifth were built after 2000. Many started as summer places and were converted to year-round use, which often leaves shallow crawlspaces, piping in unheated spaces and additions wired and plumbed at different times. Salt air adds its own wear to outdoor equipment and fittings. On older island houses, repiping and plumbing upgrades are often part of making a cottage livable through February.
Power, Storms and Wiring in Harpswell
Harpswell is one of the most outage-exposed towns on Central Maine Power's system: long, narrow necks served by lines under heavy tree cover, facing open water on both sides. In the December 18, 2023 storm, with winds up to 65 mph, all but about 100 of the town's roughly 4,750 CMP customers lost power, and two days later more than 600 were still out. The October 2017 nor'easter, the largest outage event in Maine history, did similar damage along the coast. Because every house here is on a well, losing power means losing water too, and a well pump plus a boiler circulator is a small load a generator handles easily. Generator installation on the Harpswell islands works best with the transfer switch and fuel supply planned together.
Getting to Know Harpswell
Harpswell has more coastline than any other town in Maine — about 216 miles of it, spread across a long peninsula and dozens of islands. It is also home to the Bailey Island Bridge, built in 1927–28 from granite slabs stacked in an open cribwork that lets the tide flow through — the only granite cribstone bridge of its kind in the world.
All that shoreline means nearly every Harpswell home lives with salt air, wind, and weather off the water. We choose equipment and mounting locations accordingly, so systems on Orr's and Bailey Islands last as long as they should.
Local & Independent — Not a Franchise
There is no franchise behind Aces Highlands — just a Portland-based crew that works Harpswell under its own name. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
How Your Electrical Panel Works
- Meter — measures the power the utility delivers
- Main breaker — the single shutoff for the whole panel
- Branch breakers — one per circuit, trip on overload or a fault
- Neutral / ground bus — the common return and safety path
- Panel capacity — how much headroom is left for new circuits
Homeowner Guide
Old Wiring, Explained: Knob-and-Tube and Aluminum Branch Circuits
Southern Maine has a lot of housing stock old enough to have gone through several wiring eras, and two of them come up constantly on inspection reports: knob-and-tube and aluminum branch-circuit wiring. Neither one means your house is unsafe today, but both mean something specific, and homeowners deserve the real explanation instead of a scare pitch.

Codes & Permits for Wiring & Rewiring in Harpswell
Electrical work in Harpswell is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Harpswell has no designated Local Electrical Inspector — only Local Plumbing Inspector titles are listed for its Code Enforcement Officers — so electrical work falls to the State Electrical Inspector under Maine's Office of Professional and Occupational Regulation / Electricians' Examining Board. The town has two Code Enforcement Officers rather than one, likely reflecting the workload of inspecting scattered peninsula and island properties across the town's dispersed geography.
- CPSC recognizes three permanent repair methods for aluminum branch-circuit wiring: (1) complete rewiring with copper, (2) the COPALUM crimp connection system, and (3) an approved 'alternative repair method' using a listed connector such as an AlumiConn connector to pigtail a short length of copper wire onto the existing aluminum conductor. CPSC does not list simply swapping in CO/ALR-rated devices as one of its three approved permanent repairs, and does not endorse do-it-yourself repair. cpsc.gov
- Any work extending, altering, or replacing existing wiring — including older knob-and-tube or aluminum branch-circuit wiring found in Maine's older housing stock — must be performed by a Maine-licensed electrician and brought up to the currently adopted 2026 NEC for the portion of the system being worked on. maine.gov
- Rewiring beyond the state's 'minor repair work' exemption (which covers only replacing existing switches, sockets, lamps, fuses, and repairing entrance-service equipment) requires a standard electrical permit. maine.gov
- State law: 'No electrical equipment may be installed or altered unless the person making the installation first obtains a permit from the Electricians' Examining Board, or towns/cities that have their own electrical inspector.' Exceptions to the state permit include: single-family dwellings (certification is needed on single-family dwellings, or a licensed Master electrician may verify the work); utility-company work on its own equipment; and 'minor repair work, including the replacement of lamps, fuses, lighting fixtures, switches and sockets, the installation and repair of outlets, radio and other low voltage equipment and the repair of entrance service equipment.' maine.gov

I've had an excellent experience working with them for both electrical and HVAC work as I remodel my 1785 home. I highly recommend them.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.

This team was called in by my property management company for where I rent. Elijah and his team were professional, clear speaking. Good communicators gave me the real deal. Didn't give any runaround. I trust them and want to use them for my own projects.
Wiring & Rewiring FAQs
Will my insurance company cover a home with knob-and-tube wiring?
Increasingly, no. Many insurers in Maine decline coverage or charge steep premiums for homes with active knob-and-tube, and some require replacement before closing on a sale. Rewiring resolves the insurance problem and removes a genuine fire risk at the same time.
How much does it cost to rewire a house?
Nationally, whole-home rewiring typically runs $4-$10+ per square foot depending on access, home age, and finish level — a partial rewire of only the original circuits costs far less. After walking your home, we quote a firm written price so there are no surprises.
Do you have to open up all my walls to rewire?
No. We fish new wiring through existing cavities from basements, attics, and small access openings. Some targeted drywall openings are usually necessary, but they are modest and easy to patch — nothing like the gut job people imagine.
How long does a whole-home rewire take?
Most single-family rewires take several days to a week depending on size and access. We stage the work so you keep power in the rooms you are living in, and we walk you through the schedule before we start.
Can I just add GFCI outlets instead of rewiring?
Sometimes. GFCI protection can add shock protection to ungrounded circuits and is a legitimate, code-recognized improvement. But it does not fix deteriorated insulation or overloaded conductors. We will tell you honestly which situation you have — protection upgrade or genuine rewire.
