Wiring & Rewiring for Gorham Homeowners
New Circuit Installation
Whole-Home Rewiring
Knob & Tube Replacement
When Gorham homeowners need wiring & rewiring, Aces Highlands is the local team to call. We are based at 508 Riverside St Unit 1 in Portland — a short drive from Gorham in Cumberland County — so we respond quickly and know the homes, the weather, and the codes in your area.
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 We replace outdated wiring with modern copper wiring, properly routed and protected in every wall and ceiling cavity.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.

Gorham Homes and What They Need
Gorham covers about 51 square miles west of Westbrook and is still largely rural, and its housing has grown in waves. Census estimates put the median home at 1988: about 14 percent of units were built before 1940, largely in Gorham Village and the old farm roads, while roughly a third were built since 2000 as the town became a Portland bedroom community. About 80 percent of homes are single detached houses and about 81 percent are owner-occupied, and about 5 percent are mobile homes. Newer subdivisions are spread well beyond the village, out toward Little Falls, White Rock and North Gorham. Old farmhouses can have stone foundations, add-on wiring and no ductwork, while newer colonials usually have forced air, which is why replacing an old farmhouse boiler and a subdivision furnace swap are very different jobs.
Power, Storms and Wiring in Gorham
Central Maine Power serves Gorham, and the town's tree-lined back roads leave it more exposed to long outages than denser neighbors. In the 1998 ice storm, news coverage listed Gorham among the Portland-area towns that bore the brunt of the damage, and the December 2023 windstorm again left more Cumberland County customers dark than any other county. For the many homes on private wells, an outage also cuts off water, and freezing pipes become a risk within days in January. Census figures show about 64 percent of workers drive alone and about a fifth work from home, and most households own a single-family home with a driveway, so an EV charger is easy to place. Households planning both a charger and generator installation for a Gorham home should size them together on one panel.
Getting to Know Gorham
Gorham began as "Narragansett No. 7" — one of seven townships Massachusetts granted in 1728 to veterans of the Narragansett War and their heirs — and was incorporated under its current name in 1764. On the Gorham–Windham line, Babb's Bridge spans the Presumpscot River as Maine's oldest covered bridge, originally built in 1840 and faithfully rebuilt with locally milled lumber after a 1973 fire.
Gorham today mixes centuries-old farmhouses with newer subdivisions around the village and the USM campus — two very different kinds of heating and electrical work, and we are comfortable in both.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Gorham — not a national franchise. Every technician is paid to solve the problem in front of them, not to hit an upsell quota. That is how we keep customers calling back, one honest job at a time.
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 Gorham
Electrical work in Gorham is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Not independently confirmed for Gorham for the same reason (site blocked to automated fetches). Under Maine's electrician licensing law (32 M.R.S. ch. 17), a town without its own Local Electrical Inspector defaults to a State Electrical Inspector assigned by territory under the Office of Professional and Occupational Regulation (OPOR) / Electricians' Examining Board — it was not confirmed which arrangement applies in Gorham; given the town's size (pop. ~18,300) it likely has its own certified inspector similar to Westbrook and Scarborough, but this is unverified. Fuel oil/kerosene is by far the dominant home heating fuel at 60.4% of occupied units — the highest oil-reliance of the three towns researched — indicating strong oil-to-gas/heat-pump conversion potential.
- 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
- Central Maine Power (CMP), a subsidiary of Avangrid, describes itself as serving 'approximately 670,520 electricity customers in an 11,000 square-mile service area in central and southern Maine' — the region that contains the entire Augusta-to-York corridor. Consistent with this, South Portland's own permitting page requires a CMP account/work-order number on any electrical permit tied to a service change, and Buxton's electrical permit application has a dedicated field for the applicant's CMP account number. cmpco.com
How Aces Highlands Handles Wiring & Rewiring in Gorham
- 14% of Gorham's homes predate 1940, old enough that knob-and-tube or aluminum branch wiring still turns up behind the plaster — both get brought up to current code as we go, not patched around.
- Swapping a switch or outlet for an identical one is exempt "minor repair work" under Maine law; extending or adding circuits is not, and gets its own permit before we start.
- We label circuits as we go and bring anything new up to the 2026 National Electrical Code, Maine's current standard.

Malina Foss

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.

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.

He was very friendly. He gave me an honest explanation on why I shouldn't recharge my A/C unit and what he suggested made much more sense. He really took care of everything. He is very professional, always called me with updates. 5 stars is not enough — I give this company 10 stars.

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.
