What sets our electricians apart is straightforward: 16 years of hands-on electrical work in Bethlehem, a team of licensed electricians on every job, and a commitment to being personally accountable to every customer we serve.
We are a locally owned business. When you call, you reach someone who knows this area, knows the housing stock, and knows what it takes to get your electrical system working the way it should. We pick up the phone and get it handled.
We work with all kinds of customers: homeowners dealing with a tripping breaker at midnight, landlords managing rental properties across Northampton County, property managers keeping commercial spaces up to code, and small business owners who need reliable power to keep things running. Whatever your situation, you get straight answers about your panel and wiring, no surprises, and a clear picture of what the job involves before any work begins.
We'll get your lights back on fast.
Some homes need a full rewire. Others just need one outlet fixed. We handle both, and everything in between.
Our residential electrical work covers the full range of what Bethlehem homeowners run into day to day:
Repairs and Troubleshooting - Flickering lights, dead outlets, sparking receptacles, burning smells, loss of power to a room - Tripping breaker diagnosis and circuit breaker replacement - Fuse box issues and panel faults
Outlet, Switch, and Lighting Work - Outlet and switch installation and replacement - GFCI outlet installation in kitchens, bathrooms, and garages - Recessed lighting installation, ceiling fan installation, light fixture replacement - Outdoor and security lighting, under-cabinet lighting
Panel and Wiring - Breaker panel upgrades, including 200-amp service upgrades - Dedicated circuits for dryers, ranges, kitchen appliances, and laundry rooms - Whole-home rewiring, knob-and-tube wiring replacement, and aluminum wiring remediation - Partial rewiring and code-correction wiring for older homes - AFCI and GFCI breaker installation for arc-fault and ground-fault protection
Safety and Inspections - Electrical safety inspections for older homes and pre-sale checks - Grounding and bonding assessments - Basement and sump-pump circuits
Bethlehem has a lot of older housing stock, and we know what that means in practice: panels that have not been touched in decades, knob-and-tube wiring that was never updated, and aluminum branch circuit wiring that needs careful remediation. We have done this work in homes all over the area, and we know how to handle it safely and to code.
We'll have your outlets working again in no time.
Whether this is your first repair or your tenth, we bring the same level of care and attention to every commercial job we take on.
We work with offices, retail spaces, warehouses, multi-unit buildings, and commercial properties of all sizes across Northampton County. Our commercial electrical services include:
When a business has a power problem, downtime costs money. We respond quickly, communicate clearly, and make sure the wiring done right the first time so you are not calling us back for the same issue twice.
Call and we'll get the current flowing right.
Electric vehicle ownership is growing steadily across the Lehigh Valley, and more Bethlehem homeowners are looking to charge at home rather than rely on public stations. A Level 2 home EV charger is the practical solution: faster charging overnight, no scrambling for a public spot, and a setup that works with your schedule.
We install Level 2 EV chargers for home garages and driveways, including Tesla home charging stations and other major brands. Every installation starts with a panel capacity check to make sure your existing service can handle the new 240-volt dedicated circuit. Older Bethlehem homes often need a panel assessment or a small upgrade before installation, and we will walk you through exactly what is needed and what it will cost before any work begins. All work is permit-ready and code-compliant.
A single voltage spike can damage appliances, electronics, and the wiring throughout your home. Whole-home surge protection installs directly at your main panel and catches surges before they reach your devices.
Northampton County's mix of older and newer housing stock makes this one of the more practical upgrades a homeowner can make. Older panels may need a quick evaluation before a whole-house surge protector can be added, and we will let you know upfront if that is the case. Proper grounding and bonding is part of every surge protection installation we do, because the protection is only as good as the system it is tied into.
Ready to get the power sorted?
Electrical problems do not wait for a convenient time. A tripping breaker, a dead outlet, or a complete loss of power to part of your home needs attention now, not next week. We offer same-day scheduling for electrical repairs and emergency availability for situations that cannot wait.
When you call, we give you a clear picture of what the work involves and what it will cost before we start. No vague estimates, no surprise charges added after the fact. If the job turns out to be more involved than expected, we tell you before we proceed, not after. Common questions we hear include what a panel upgrade costs, what rewiring a room runs, and what EV charger installation typically involves. We answer all of those honestly, based on what we actually see on the job.
We answer the phone. We dispatch the electrician. We keep it simple.
We are based in Bethlehem and serve customers throughout Northampton County and the wider Lehigh Valley. Our service area includes:
If you are nearby and need an electrician, there is a good chance we have already worked in your neighborhood. Call to confirm we cover your area.
Every electrical job we complete is done to current code. That matters for a few reasons. First, code-compliant work is safe work. Electrical fires, shock hazards, and equipment damage are almost always the result of wiring that was installed incorrectly or never updated to meet current standards. Second, code-compliant work protects you when you sell your home or file an insurance claim. Inspectors and insurers look at the electrical system, and work that was done right holds up under scrutiny.
We do not cut corners to save time, and we do not leave a job until it meets the standard it is supposed to meet. That applies to a single outlet replacement and a full panel upgrade equally.
We work with homeowners, landlords, property managers, and small business owners across Bethlehem and Northampton County. Our residential customers range from owners of older South Side row homes dealing with aging wiring to newer homeowners adding EV chargers or upgrading their panels. On the commercial side, we serve offices, retail spaces, warehouses, and multi-unit rental properties.
We have been working in Bethlehem since 2010, which means we know the neighborhoods and the kinds of electrical systems that come with them. Older homes on the South Side and throughout the surrounding area often have knob-and-tube or aluminum wiring, undersized panels, and grounding issues. We have seen these systems up close for over sixteen years and know how to handle them correctly.
We stand behind every job we complete. If something we did is not right, we come back and make it right. We do not consider a job finished until the work meets code and performs the way it should.
Yes. When a job requires a permit, we handle the permit process as part of the work. Code-compliant, permitted work protects you when you sell your home, file an insurance claim, or have a buyer's inspector look at your electrical system. We do not skip that step to save time.
It means the people you talk to and the people who show up at your door are part of this community. We pick up the phone and get it handled, and when we take on a job, we are personally accountable for how it turns out. That accountability is built into how we work.
If an issue comes up with work we performed, call us and we will come back out to address it. We do not pass the problem off or make you explain it to someone who was not there. We track our jobs and stand behind them.
We treat your home the way we would treat our own. That means covering work areas, cleaning up at the end of the job, and being careful with walls, floors, and finishes when running new wiring or accessing existing circuits. We leave the space the way we found it, minus whatever problem we came to fix.
DER Electric has been the electrician Bethlehem homeowners and businesses have counted on since 2010. Sixteen years in this area means we know the neighborhoods, the housing stock, and what it takes to do the job right.
We live here. We wire here. We stand behind our work.
If you have an electrical problem to solve or a project to get started, call (484) 916-4289 for a quote. We will talk through what you need, give you an honest answer on cost, and get a licensed electrician out to you as soon as possible.
From a single dead outlet to a full panel upgrade, we handle the electrical work that keeps Bethlehem homes and businesses running safely. The table below covers every service we offer in this area, who it is best suited for, and what you should know before scheduling. If you have questions about a specific job, call us and we will walk you through it.
| Type of Work | What's Included | When You Need It | Worth Knowing |
|---|---|---|---|
| Code-Correction Wiring |
| homeowners who received a failed inspection, an insurance requirement, or a notice from a home sale | Code corrections are often straightforward once we know exactly what is flagged. We give you a clear scope before any work begins. |
| Electrical Panel & Service UpgradesMost Popular |
| older homes adding appliances, EV chargers, or generators, and any property with a fuse box still in service | A properly sized panel is the foundation of a safe electrical system. We size the new panel to your actual demand and handle the permit and inspection process. |
| Knob-and-Tube & Aluminum Rewiring |
| owners of Bethlehem homes built before 1980 with original or partially original wiring | Many insurers restrict or surcharge coverage on homes with knob-and-tube or aluminum branch wiring. Work is performed by licensed electricians and brought fully up to current code. |
| Dedicated Appliance Circuits |
| homeowners adding a large appliance, workshop equipment, or any load that needs its own circuit | Dryers, ranges, and large appliances require a dedicated 240-volt circuit. Running one from an already-loaded panel may require a capacity evaluation first. |
| Wiring & Circuit Installation |
| homes being renovated, additions, or any property that needs new circuits added | Northampton County's older housing stock means rewiring projects are common here. We handle targeted rewiring of one section or the whole house. |
| Outlet & Switch Installation |
| homeowners updating older receptacles, adding outlets, or bringing a circuit up to code | Every outlet job includes proper grounding and bonding. GFCI protection is required in kitchens, bathrooms, garages, and outdoor areas. |
| Backup Generator Installation |
| homeowners and businesses preparing for nor'easters and extended outages in Northampton County | The transfer switch is the critical safety component. It isolates your home's wiring from the utility line so power cannot back-feed onto the grid during an outage. |
| Whole-Home Surge Protection |
| any homeowner with sensitive electronics, smart home devices, or appliances worth protecting | One device installed at the panel protects every circuit in the house. It is a straightforward addition during any panel or service visit. |
| Electrical Repairs & Troubleshooting |
| any homeowner or business owner with an unexplained electrical problem | We trace the source of the problem, not just the symptom. A thorough diagnosis prevents the same issue from coming back. |
| Lighting Installation |
| homeowners updating interior lighting or adding outdoor security and landscape fixtures | Outdoor wiring requires weatherproof-rated fixtures and GFCI protection to meet Pennsylvania code and hold up to local weather. |
| Basement & Sump-Pump Circuits |
| homeowners finishing a basement or adding a sump pump, dehumidifier, or workshop in the lower level | Sump pumps should be on a dedicated circuit so a tripped breaker from another load does not leave the pump without power during a storm. |
| EV Charger Installation |
| Bethlehem homeowners adding a home EV charger for daily charging | A Level 2 charger requires a dedicated circuit and enough panel capacity to support it. Many homes in the area need a panel evaluation before installation. |
| Breaker & Fuse Repair |
| homes or businesses with breakers that trip repeatedly or a fuse box still in service | A breaker that trips repeatedly is a warning sign, not a nuisance. We find out whether the issue is the breaker, the circuit load, or the panel itself. |
| Electrical Safety Inspections |
| buyers, sellers, landlords, and homeowners who want a clear picture of their system's condition | In older Bethlehem properties, inspections regularly turn up issues that have been quietly present for years. Knowing what is there is always better than guessing. |
| Ceiling Fan Installation |
| homeowners adding or replacing ceiling fans in any room | Older ceiling boxes are often not rated for fan weight. We check the box and brace before installation so the fan is mounted safely. |
How do I know if my panel needs to be upgraded?
Common signs include breakers that trip repeatedly, lights that dim when a large appliance starts, a fuse box still in service, or a panel that simply does not have enough open slots for the circuits you need. If you are planning to add an EV charger, a generator hookup, or significant new load, a panel evaluation should come first. We look at the panel, assess your current demand, and give you a straight answer about whether an upgrade makes sense.
What causes breakers to trip over and over?
Repeated tripping usually points to one of three things: a circuit that is carrying more load than it was designed for, a failing breaker that no longer holds its rated current, or a wiring problem somewhere on the circuit. Occasionally it signals that the panel itself is undersized for the home's demand. We diagnose the actual cause rather than just resetting the breaker and hoping it holds.
Is the work permitted and inspected?
For jobs that require a permit under Pennsylvania and local Bethlehem codes, we handle the permit process as part of the job. Permitted work is inspected by the local authority, which gives you documentation that the installation meets current code. That matters for insurance, for home sales, and simply for knowing the work was done correctly.
Work Performed by Licensed Electricians
Every job we take on is handled by licensed electricians from start to finish. That means the work meets code, holds up to inspection, and gives you documentation you can rely on for insurance and home sales.
How do I know if the wiring in my older Bethlehem home is safe?
Homes built before 1980 may have knob-and-tube wiring, aluminum branch wiring, or both. Neither is automatically a crisis, but both require an honest assessment. Knob-and-tube lacks a ground conductor and was not designed for modern electrical loads. Aluminum branch wiring can loosen at connections over time and create heat at those points. An inspection gives you a clear picture of what is in the walls and what, if anything, needs to be addressed.
What does a Level 2 EV charger installation involve?
A Level 2 charger runs on a dedicated 240-volt circuit, similar to a dryer outlet. The installation involves running that circuit from your panel to the charger location, mounting the charging unit, and confirming the panel has enough capacity to carry the added load. Many homes in the Bethlehem area need a panel evaluation before the charger goes in, and some need a panel upgrade to make the load work safely. We handle the full electrical side of the job.
How does backup generator hookup work, and why does the transfer switch matter?
We connect the generator to your home's electrical system through a transfer switch, which is the component that makes the whole setup safe and legal. The transfer switch isolates your home's wiring from the utility line whenever the generator is running, which prevents power from back-feeding onto the grid and endangering utility workers. Without a proper transfer switch, a generator hookup is a code violation and a genuine safety hazard. We size the circuit, install the transfer switch, and integrate everything with your existing panel.
Experienced With Older and Newer Homes
We work regularly in Bethlehem's older housing stock, where knob-and-tube wiring, aluminum branch circuits, and undersized panels are common. We also wire new construction and additions. Whatever the property, we know what we are looking at.
Do I need to be home while the work is being done?
For most jobs, yes. We need access to the panel, the affected circuits, and often multiple rooms. For larger jobs like rewiring or panel replacement, someone should be available for the duration. When you call to schedule, we will let you know what access we need so you can plan accordingly.
When should I call an electrician instead of trying to fix it myself?
Anything beyond replacing a light bulb or a plug-in device is worth a call. Outlet and switch replacement, breaker issues, wiring work, and anything inside the panel are jobs for a licensed electrician. The risk with electrical DIY is not just a shock hazard in the moment. Improper wiring can create fire risk that shows up weeks or months later. If you are not certain, call and describe what you are seeing. We will tell you honestly whether it is something we need to handle.
Same-Day and Emergency Availability
Electrical problems do not wait for a convenient time, and neither do we. We are available for same-day service and after-hours emergencies for both residential and commercial customers across Northampton County.
Are warm or buzzing outlets something to worry about?
Yes. A warm outlet usually means there is resistance at a connection, which generates heat. A buzzing sound from an outlet or switch often points to a loose wire or a failing device. Both are worth addressing promptly. Left alone, a loose or overheating connection can damage wiring inside the wall or become a fire hazard. Call us and we will get a look at it.
What does GFCI protection do, and where is it required?
A GFCI outlet or breaker monitors the circuit for a ground fault, which is an unintended path for current, and cuts power in a fraction of a second if it detects one. That response time is fast enough to prevent a serious shock. Code requires GFCI protection in kitchens, bathrooms, garages, unfinished basements, outdoor areas, and anywhere near water. If your home does not have GFCI protection in those locations, we can add it as a standalone job or as part of any other electrical visit.
How long does a panel upgrade or whole-home rewire take?
A panel upgrade typically takes most of a working day. A whole-home rewire depends on the size of the house and the condition of the existing wiring, but plan on multiple days for a full rewire of an average-sized home. When you call, we will ask about the property and give you a realistic time estimate before we schedule. We confirm the details once we are on-site and have seen the full scope.
Every property is a little different, and the right solution depends on what is actually in your walls. Call us at (484) 916-4289 and we will give you a straight answer about what the job involves and what it will cost.
