When a renovation is underway or a new appliance is going in, the electrical side of the job needs to be figured out before the walls close up or the equipment arrives. Getting a licensed electrician involved early means the circuits are sized correctly, the panel can carry the added load, and the work passes inspection without a callback. Alphin Watts Electric handles that planning work for Cambridge homeowners, rental property owners, and businesses, and we handle the reactive work too: the tripped breaker at midnight, the outlet that stopped working, the panel that has been running on borrowed time.
Cambridge has a lot of older housing, multi-unit buildings, and commercial properties that mix original construction with decades of additions and renovations. That combination creates real electrical complexity, and we see it regularly. Whether the job is straightforward or involves tracing a fault through wiring that has been touched by four different hands over fifty years, we work through it the same way: diagnose first, explain what we find, then complete the work correctly.
The rate is confirmed on the call before we book anything. When you describe the job, we give you a price and explain what it covers. If the scope changes once we are on site because something turns up behind the wall or at the panel, we talk it through before the work continues. Nothing is added to the bill without a conversation first.
What affects the quote is the nature of the job: the circuit run length, the materials the work requires, whether the panel needs attention before a new circuit can be added, and how accessible the wiring is. A straight outlet replacement in a finished room is a different job from running a new circuit through an older multi-unit building. Call us at (857) 626-9359, describe what you are dealing with, and we will give you a straight answer on the rate.
The calls that come in most often are about something that stopped working or something that is behaving wrong. A breaker that trips when a particular appliance runs, a set of outlets that went dead, a light fixture that flickers under load. These symptoms can have simple causes or they can point to something deeper in the wiring or at the panel. We run a proper diagnostic before recommending any repair, because replacing a breaker that is not the actual problem just moves the fault somewhere else.
In older Cambridge properties, wiring that was installed in stages over many decades can make fault finding more involved. Circuits that were extended without documentation, knob-and-tube sections that were spliced into later wiring, or aluminum branch circuits that have developed loose connections at outlets: these take more time to trace but the process is the same. We find the fault and fix it right.
A panel that was installed when the building had a fraction of its current electrical load is a common situation in Cambridge. When breakers trip under ordinary use, the panel runs warm, or there is simply no room to add a circuit, the panel itself is the problem. We handle full panel replacements, 200-amp service upgrades, and subpanel installation for buildings where the main panel is too far from where the new load needs to be.
Before any upgrade, we work out what the panel needs to carry, including any new circuits being added at the same time. Grounding and bonding are part of every panel job. Code-compliant wiring throughout the installation is not optional, and wiring work is checked against code before sign-off.
Adding a circuit for a new appliance, finishing a basement, wiring a home office, or bringing an older unit up to current outlet standards: these are installation jobs that come out of how people actually use a property, not from something going wrong. For landlords turning over units, that often means GFCI outlets in kitchens and bathrooms, updated switch wiring, and hard-wired smoke detectors where required. For homeowners adding a dryer or an electric range, it means a dedicated 240-volt circuit sized to the appliance. The service page carries the full breakdown of what each installation type involves.
Smart switches and dimmers require a neutral wire at the switch box, and older Cambridge homes often do not have one. We assess the existing wiring before recommending a switch, and where a neutral is missing we work out the right solution for that box rather than leaving the customer with a switch that does not work correctly.
Running a supply to a detached structure means a dedicated circuit from the main panel, proper conduit or underground wiring, and a subpanel in the structure if more than one or two circuits are needed. Electric gate operators have their own load requirements and need a correctly sized dedicated circuit. We handle the full electrical run from the panel to the endpoint.
A panel with unlabelled or mislabelled breakers is a safety issue and a practical problem every time work needs to be done. We identify every circuit, test each one, and label the panel clearly. For multi-unit buildings where circuits have been added over the years without documentation, this is work that pays for itself the first time a fault needs to be traced.
Outdoor circuits require weatherproof outlets, correct conduit where wiring is exposed, and proper grounding throughout. We install security lighting, motion sensor lights, flood lights, and landscape lighting for residential and commercial properties. Every outdoor installation is held to the same code standard as interior work.
A panel-level surge protection device protects every circuit in the building from voltage spikes caused by lightning, utility events, and large appliances cycling on and off. It is installed at the main panel and requires no changes to the rest of the wiring. For properties with a lot of electronics or appliances, it is one of the more practical upgrades available. We treat your home and its wiring the way we would our own, and that includes recommending protection that actually matters.
Well pump circuits and irrigation controls need dedicated wiring sized to the motor load, with proper grounding and protection against surge damage. We run these circuits from the panel, size them correctly, and install the disconnect and protection devices the installation requires.
Most significant electrical work, panel upgrades, new circuit runs, service upgrades, and EV charger installations, requires a permit and inspection. The specific requirements depend on the scope of the job and the jurisdiction. We handle the permit process as part of the work, so the installation is inspected and signed off correctly.
Permit timing matters for renovation projects where other trades are waiting on the electrical inspection before they can close walls or finish a space. We factor that into how the job is scheduled. If you are coordinating electrical work with a larger renovation, let us know when you call and we will talk through the sequence.
the electrical services page is where the process is written out.
When the work is complete, we do not leave before confirming it is correct. Outlets are tested, breakers are verified against the circuits they protect, and GFCI and AFCI devices are checked for proper operation. If the panel was touched, every breaker is confirmed and the panel is labelled accurately.
For properties being sold or re-let, that documentation matters. A buyer's inspector who finds a correctly labelled panel, code-compliant wiring, and proper GFCI coverage throughout the building has less to flag. A tenant moving into a unit with documented, inspected electrical work is in a better position than one inheriting whatever the last renovation left behind. We keep your home powered and safe, and we make sure the paperwork reflects the work that was done.
We take calls every day from 6:30 AM to 10:30 PM. Same-day appointments are often available when the schedule allows, and we take calls on weekends. For problems that cannot wait, call (857) 626-9359 and describe what you are seeing. We will let you know how quickly we can get someone out.
For occupied rental units and commercial properties that need to stay open, we work around the people who are there. That means scheduling the work at a time that minimizes disruption, letting you know what to expect before we arrive, and completing the job without leaving the space in a state that causes problems for whoever is using it. Prompt response, even for last-minute electrical calls, is part of how we work.
We serve Cambridge and the surrounding area throughout Middlesex County. That includes Somerville, Watertown, Medford, Belmont, and Arlington. If your property is in one of those communities or nearby, call us and we will confirm coverage for your address.
The same process applies across the whole area: call for a quote, get a rate before anything is booked, and schedule a visit. You know who to call if you ever need us again.
Yes, and it is worth mentioning when you call. Equipment that cannot lose power, even briefly, changes how we sequence the work and whether a temporary supply or generator connection needs to be in place during the job. We plan around it rather than treating it as an afterthought.
The items that come up most often in buyer inspections are ungrounded outlets, missing GFCI protection in kitchens and bathrooms, an undersized or outdated panel, and visible wiring that does not meet current code. Correcting those before listing removes a common negotiating point and gives buyers confidence in the property.
A warm or discolored faceplate is a sign of heat buildup at the connection behind the outlet, which can come from a loose wire, an overloaded circuit, or a failing device. It is not something to leave in place. Turn off the circuit at the breaker and call (857) 626-9359 so we can open it up, find the cause, and correct it before it becomes a bigger problem.
Sparking, a burning smell, a panel that is warm or buzzing, partial power loss across the home, and any wiring that has been physically damaged all warrant a call right away rather than waiting. We take calls every day from 6:30 AM to 10:30 PM. If you are describing something that sounds urgent, tell us that when you call and we will do our best to get someone out the same day.
An electrical safety inspection can be scheduled as part of due diligence on a purchase. We check the panel, wiring condition, outlet grounding, GFCI and AFCI coverage, and overall code compliance, and we explain what we find in plain terms. Call (857) 626-9359 to describe the property and arrange a visit.
Yes. We work around occupied units regularly. When you call, let us know that a tenant is in the property and what times work for them. We schedule the visit to minimize disruption and confirm the appointment before anyone heads out, so the tenant is not left waiting without information.
When electrical work is scheduled after walls are already closed or finishes are in place, some of what would have been straightforward becomes a much more involved job. Fishing wire through finished walls takes longer and may require more access points. Involving us before the walls close is always the more efficient approach.
A panel upgrade sometimes reveals that the service entrance conductors or the meter base are also undersized or deteriorated. When that is the case, we address the full path from the utility connection to the panel so the completed work is safe and code-compliant throughout, not just at the panel itself.
Some older breaker types are no longer manufactured, and sourcing a direct replacement can be difficult. In those cases, we assess whether a compatible replacement is available from the original manufacturer or whether the panel itself should be replaced. Using an incompatible breaker is not a safe workaround, and we will not do it.
In many cases, yes. A phased rewire lets us work through the home section by section, which can make the project more manageable for occupied properties. We assess the wiring condition and talk through what order makes the most sense based on where the greatest safety concerns are and how the home is being used.
Coordination with the utility is part of a service entrance or meter upgrade. We handle the electrical work on the property side and communicate with the utility about what needs to happen at the meter or the service drop. You do not have to manage that conversation yourself.
It often does. Older multi-unit buildings in Cambridge frequently have wiring that was installed in stages, with different systems running through the same walls. That can mean more time for diagnostics, more materials for a rewire, or a panel upgrade that needs to happen before a new circuit can be added. We assess what is in place and explain the scope before the quote is finalized.

Cambridge's housing stock runs from pre-war triple-deckers to newer commercial builds, and the electrical work each one needs is different. We handle everything from a single outlet replacement to a full service upgrade, and we bring the same attention to code compliance and workmanship to every job. Below is a plain-language look at what we do, who each service fits, and what is worth knowing before you call.
| Service | What's Included | Best For | Things to Know |
|---|---|---|---|
| Ceiling Fan Installation | fan and wiring installationceiling box upgradescircuit load check | rooms where the existing box was never rated for a fan | A standard light fixture box cannot safely support a ceiling fan. We upgrade the box as part of the installation when needed. |
| Electrical Repairs & Troubleshooting | flickering lightsdead outletstripping breakerscircuit diagnostics | homeowners and landlords dealing with an active electrical problem | A symptom like a flickering light or a dead outlet often points to a deeper wiring issue. We diagnose before we repair so the fix addresses the actual cause. |
| Basement & Sump-Pump Circuits | finished basement wiringdedicated sump pump circuitGFCI protection in wet areas | homeowners finishing a basement or adding reliable sump pump power | A sump pump should run on its own dedicated circuit so a tripped breaker elsewhere cannot take it offline during a storm. |
| Backup Generator Installation | transfer switch installationgenerator-to-panel wiringgrounding and bondingpost-installation inspection | homes and businesses that need essential circuits running when the grid goes down | A transfer switch is a code requirement that prevents the generator from back-feeding the utility line. We inspect the completed hookup after installation to confirm everything is operating correctly. |
| Wiring & Circuit Installation | new circuit runshome addition wiringgarage and basement circuitssubpanel installation | renovations, additions, and finished spaces that need circuits wired from scratch | Permit and inspection requirements apply to most new wiring work. We handle that as part of the job. |
| Lighting Installation | recessed lightingpendant and chandelier fixturessecurity and motion lightsweatherproof exterior outlets | interior upgrades and exterior security lighting on single-family and multi-family homes | Exterior lighting circuits require proper grounding and weatherproof materials. All outdoor installations are checked against code before sign-off. |
| Breaker & Fuse Repair | breaker replacementfuse box repairpanel fault diagnosis | homes where a breaker will not reset or a fuse keeps blowing | A breaker that trips repeatedly is signaling an overloaded or faulted circuit. Replacing the breaker without finding the cause does not solve the problem. |
| Electrical Safety Inspections | panel and wiring condition reviewGFCI and AFCI coverage checksmoke and CO detector inspectionpre-sale and rental compliance | home buyers, sellers, landlords, and property managers who need a full system review | We perform inspections for home purchases, pre-sale preparation, rental compliance, and renovation sign-off. Hard-wired smoke and carbon monoxide detectors are part of what we inspect and install where required. |
| Electrical Panel & Service UpgradesMost Popular | 200-amp service upgradespanel replacementload calculationsfuse box conversions | homes with older 60- or 100-amp service that can no longer carry modern electrical loads | We run a load calculation before any upgrade to size the panel correctly for existing and planned circuits, including EV chargers and dedicated appliance runs. |
| Outlet & Switch Installation | GFCI outlet upgradesUSB outletsdimmer switchesstandard outlet additions | homeowners, landlords, and property managers keeping units functional and code-compliant | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor areas. Older units often lack it entirely. |
| Knob-and-Tube & Aluminum Rewiring | knob-and-tube identification and replacementaluminum branch circuit remediationwhole-home rewiringcode-correction wiring | pre-1950s Cambridge homes with original wiring or aluminum branch circuits from later renovation eras | Knob-and-tube wiring has no ground and cannot support GFCI or AFCI protection. Aluminum branch wiring loosens at connections over time, which creates a fire risk at outlets and fixtures. |
| Dedicated Appliance Circuits | dryer and range circuitsrefrigerator and dishwasher circuits240-volt runssump pump circuits | kitchens and laundry rooms where appliances share circuits they were never meant to share | A dedicated circuit means one appliance, one circuit. We size the wire and breaker to match the appliance's actual rated draw. |
| EV Charger Installation | Level 2 charger installationdedicated 240-volt circuitpanel capacity checkpermit coordination | EV owners who want reliable home charging without relying on a standard 120-volt outlet | A Level 2 charger requires a dedicated 240-volt circuit and a panel that can carry the added load. We confirm panel capacity before any circuit work starts. |
| Whole-Home Surge Protection | panel-mounted surge deviceprotection from lightning and utility spikesappliance and electronics coverage | homeowners who want to protect electronics, appliances, and wiring from voltage events | A whole-home surge device is installed at the main panel and protects every circuit in the building.
