Electrical Problems Don’t Fix Themselves
Harwich homes take a beating. Salt air off Vineyard Sound and Buzzards Bay corrodes panels and outdoor connections, nor’easters knock out power for days, and much of the housing stock — from antique Capes to 1970s ranches — is still running on wiring that was never designed for today’s loads. If you have noticed any of the following, it is time to have a licensed electrician take a look:
Breakers that trip often — a sign your panel is overloaded or aging out.
Flickering or dimming lights — loose connections or an undersized service.
Warm outlets, buzzing sounds or a burning smell — call us right away; these are fire risks.
Not enough outlets or circuit space — common in older Harwich homes that have been added onto over the years.
A panel over 40 years old — Cape Cod’s corrosive coastal environment shortens the life of electrical equipment.
You want to add a generator, EV charger, hot tub or mini split — most of these require a panel evaluation first.
Residential Electrical Services in Harwich
Whether it is a single outlet in a Harwich bungalow or a full rewire of a waterfront home in Harwich, our lead technicians — every one a licensed journeyman or master electrician — show up on time, explain the work in plain English and leave the place cleaner than they found it. We serve year-round residents and second-home owners alike, and if you are off-Cape we can walk you through the job by FaceTime.
Electrical Repairs & Troubleshooting
Dead outlets, tripping breakers, a switch that never worked right. We diagnose the actual cause instead of guessing, fix it to code and tell you what else we noticed while we were in there — without the upsell.
Panel Replacements & Service Upgrades
A 100-amp panel was fine in 1985. Add central air, an induction range, an EV charger and a hot tub and it is not. We replace corroded, undersized and known-problem panels (Federal Pacific, Zinsco) and upgrade 100-amp services to 200 amps so your Harwich home can handle everything you want to plug into it — safely.
New Construction & Remodeling
Building in Harwich, renovating a kitchen or finishing a basement? We wire new homes, additions and renovations from rough-in to final inspection and coordinate directly with your builder so nothing holds up the schedule.
Electrical Inspections
Buying a house or renting out a seasonal property? Our inspection covers the panel, wiring, grounding, outlets, smoke and CO detectors, and overall system condition, with a straightforward report explaining what is fine, what is worth monitoring, and what needs immediate attention.
Smoke & CO Detectors, Outlets, Switches, Ceiling Fans
The everyday jobs matter too. We install hard-wired smoke and carbon monoxide detectors that meet Massachusetts requirements, add GFCI protection in kitchens, bathrooms and outdoor spaces, replace worn switches and outlets, and properly install and wire ceiling fans — no wobble, no guesswork.
Power outages on Cape Cod aren’t just inconvenient...they trigger a chain reaction. An aging grid, strained by larger, high-demand homes, means outages are more frequent and unpredictable. When power goes out, sump pumps stop, basements flood, food spoils, and homes on wells quickly lose running water, turning a simple outage into costly damage and major disruption. What starts as a flicker can quickly escalate into structural damage, unexpected expenses, and days of disruption. It’s a reality of coastal living, but one that can be planned for and managed with the right preparation.

Generac Generator Installation & Service in Harwich
Anyone who has ridden out a January nor’easter or a late-summer tropical storm in Harwich knows the drill: the lines come down, the power goes out, and the sump pump, fridge and heating system all stop at once. A Generac standby generator turns that ordeal into a non-event. It senses the outage and restores power automatically within seconds — whether you are home or 300 miles away.
Cape Cod Electrical is a Generac-authorized dealer with more than 14 years of generator experience and a Generac-certified service technician on staff. We manage the entire project:
-
Load calculation: We size the unit to your home, from partial-home backup to whole-home standby.
-
Installation: Generator pad, transfer switch wiring, gas fitting, permits and town inspection.
-
Annual service: Maintenance visits keep the battery, oil and controls ready for the next storm.
-
Repairs: We service Generac units we installed and those we didn’t.
EV Charger Installation in Harwich
Charging overnight in your own driveway beats hunting for a public charger on Route 28. We install Level 2 home charging stations for all major EV brands — including Tesla, Ford, Rivian, Hyundai, Chevy and more — as well as commercial chargers for Harwich businesses, inns and condo associations. Every installation is safe, code-compliant and properly permitted, and we will let you know upfront if your electrical panel needs an upgrade to support the additional load.
Ductless Mini Split Installation in Harwich
Most Harwich homes were built without ductwork, making ductless mini-splits a smart way to add air conditioning and efficient heating without tearing open walls. Cape Cod Electrical is a Mitsubishi Diamond Contractor, and we install both the systems and the electrical infrastructure needed to power them, so you can work with one contractor instead of two.
Why Harwich Homeowners Choose Heat Pumps
-
Lower utility bills: Heat pumps move heat instead of generating it, so they cost far less to operate than electric baseboard heating or oil.
-
Reliable winter heating: Mitsubishi cold-climate units deliver 100% heating capacity at -10°F, providing more than enough performance for Cape Cod winters.
-
Room-by-room control: Condition your sunroom or upstairs bedrooms without having to heat or cool the entire house.
-
Fast installation: Most systems can be installed within one to three days.
-
Rebates: As a Mass Save Heat Pump Installer, we help you access available rebates and 0% financing options.
Lighting Design, Recessed & Outdoor Lighting
Good lighting can transform the feel of a home. We design and install custom interior lighting, including recessed lighting, under-cabinet lighting and Lutron RA smart lighting controls, to improve functionality, efficiency and appearance. Outdoors, professionally installed landscape, pathway and security lighting enhances curb appeal and makes the walk from the driveway safer on dark February nights.

Why Harwich Homeowners Choose Cape Cod Electrical
Uneven Temperatures, Outdated Systems, and No Easy FiX
Many homes on Cape Cod were not designed to accommodate modern heating and cooling needs. We see it every day: upstairs bedrooms that are too hot in the summer and freezing in the winter, additions that never feel as comfortable as the rest of the house, and older homes without ductwork.
Homeowners often try to address these issues with window units, electric baseboard heaters or space heaters. These solutions can be inefficient, expensive to operate and unable to fully resolve the problem. In construction and remodeling projects, we also see heating and cooling systems that are poorly planned or treated as an afterthought. This can lead to uncomfortable living spaces, higher energy costs and systems that fail to perform as they should.
At the end of the day, most homeowners are dealing with:
-
Rooms that are never consistently comfortable
-
Heating and cooling systems that are expensive to operate
-
Installations that look sloppy or out of place
-
No clear path toward a reliable, long-term solution
