We started in 2012 with a simple idea: Reading needed an electrical contractor that would treat every job, big or small, with the same level of care. What began as a small operation has grown into a trusted name across the county, built on referrals, repeat customers, and a reputation for doing the work right the first time.
We are locally owned and operated electricians. Every call that comes in is handled by someone who lives and works in this community. That means faster response, better local knowledge, and a genuine stake in the outcome of every job we take on.
Whether it is a single outlet or a full panel upgrade, we approach every service call the same way: we find the actual cause of the problem before we touch anything.
The most common calls we get involve dead outlets, flickering lights, breakers that keep tripping, and circuits that will not reset. These are not always simple fixes. A tripping breaker could point to an overloaded circuit, a failing breaker, or a wiring fault deeper in the system. A flickering light might be a loose connection at the fixture or a sign of a more serious issue in the panel.
We diagnose the root cause, not just the symptom. Where code requires it, we install GFCI and AFCI outlets and breakers as part of the repair, so the fix also brings the affected area up to current standards. The wiring done right the first time means fewer callbacks and a safer home. We make the fix and leave it tidy.
Fourteen years of work across Reading and Berks County means we have handled just about every electrical situation a residential or commercial property can present. Our team works on older homes with outdated wiring, newer builds with modern panel requirements, and everything in between.
All work is performed by licensed electricians who understand Pennsylvania's electrical code and how it applies to properties in this area. That matters when you are dealing with a safety issue, preparing for a home sale, or making improvements that need to hold up to inspection.
Property managers trust us to keep their buildings powered, and panel work is often at the center of that. Older panels simply were not built to handle the electrical load that modern homes and commercial spaces demand. If your breakers are tripping regularly, your lights dim when appliances run, or you are planning a renovation, a panel evaluation is a good starting point.
We handle residential upgrades from 100-amp to 200-amp service, commercial panel replacements, and subpanel installation for garages, additions, and outbuildings. Every upgrade starts with a load calculation so you know exactly what the new service needs to support. We also coordinate the service-entrance and meter work that goes along with a full service upgrade.
We show up on time and ready to wire, and we keep the job moving so your property is not left without power any longer than necessary. We'll get the job wired and finished.
These are the jobs homeowners call about most, and we handle all of them. Outlet and switch installation, GFCI and AFCI upgrades, dimmer switches, recessed LED lighting, ceiling fan wiring, interior fixture replacement, and outdoor lighting are all part of our regular work.
Recessed and LED lighting upgrades are one of the most popular requests we get. They improve the look and function of a space while reducing energy use, and the wiring work involved is a good opportunity to check the condition of nearby circuits at the same time.
We also install weatherproof exterior outlets and outdoor fixtures for front entries, back patios, and garage areas. All outlet and switch work is done to current code, with GFCI and AFCI protection installed wherever required. Call us and we'll walk you through the fix.
Every job we complete is held to current electrical code. That is not a marketing line. It is how we protect our customers and make sure the work holds up over time.
We pay attention to grounding and bonding, proper circuit sizing, and the specific code requirements that apply to different areas of a home or commercial property. When we find something that is out of compliance during a repair or installation, we let you know clearly and explain your options before we proceed.
This approach matters especially in older Berks County homes, where the wiring may predate current safety standards. We handle those situations with care, not pressure.
Getting your electrical problem handled starts with a quick call. But some jobs go deeper than a single repair, and we are equipped for those as well.
Dedicated circuits are essential for kitchens, laundry rooms, workshops, and major appliances. Running a refrigerator, dishwasher, or electric dryer on a shared circuit creates ongoing problems. We size and install dedicated circuits to match the load and run them back to a panel that can support them properly.
Reading and the surrounding area have a significant stock of older homes, and some of them still carry knob-and-tube or aluminum wiring. These are genuine safety and code concerns, not scare tactics. We handle full and partial rewiring projects, replacing outdated wiring with modern materials and bringing the affected circuits up to current standards.
Whole-home surge protection is worth mentioning here as well. A single surge event can damage appliances, electronics, and HVAC equipment throughout a property. A whole-home surge protector installed at the panel intercepts those events before they reach your devices. It is a straightforward installation that offers real protection, and it is something we recommend for most homes and commercial properties. We offer prompt response, even for last-minute electrical calls, so if a surge event has already caused damage, call us and we will assess what needs attention.
We know schedules shift, so we keep booking flexible, and that applies to newer services like EV charger installation and generator hookups as much as it does to standard repairs.
EV charger installation is a dedicated circuit job. We evaluate your panel, confirm available capacity, run the circuit, and install the outlet or hardwired unit. If the panel needs an upgrade to support the load, we handle that as part of the same project. We work with homeowners adding a charger for personal use and commercial clients outfitting parking areas for tenants or employees.
Generator hookups are about the transfer switch and the wiring connection, not selling you a unit. We install manual and automatic transfer switches, run the wiring from the switch to the panel, and make sure the system is set up to operate safely when the power goes out. Both services require a panel evaluation first, and we include that as part of the planning conversation.
Quick response. Straight pricing. No surprises at the panel.
An electrical inspection is useful in more situations than most people realize. Home buyers use them to understand what a property's electrical system actually looks like before closing. Sellers use them to catch issues before they surface during a buyer's inspection. Landlords and property managers use them to stay ahead of code requirements and keep tenants safe.
We inspect wiring, panels, outlets, grounding, bonding, and the condition of visible circuits throughout a property. We also check smoke detector and carbon monoxide detector wiring as part of a safety visit. After 14 years of working in Reading-area homes and commercial buildings, we know what to look for and how to explain what we find in plain terms.
Inspections often catch issues before they become emergencies. That is the point.
We are based in Reading and serve the full Berks County area, including Wyomissing, Shillington, Muhlenberg Township, Exeter Township, Birdsboro, and Kutztown. Whether you are a homeowner in a city row house, a landlord managing a multi-unit building, a property manager overseeing a commercial space, or a small business owner dealing with an electrical issue, we are close by and ready to help.
Our customers include homeowners, contractors, property managers, and small businesses throughout the county. We know the area well, and that local knowledge shows up in how we approach every job.
Getting your electrical problem handled starts with a clear conversation. When you call, describe what you are experiencing and we will tell you what kind of visit makes sense. Before any work begins, we provide a clear estimate that covers what we are doing and what it will cost. No surprise fees. No work started without your approval.
We offer same-day scheduling when availability allows, and we are reachable for after-hours and emergency calls as well. All work is performed by licensed electricians, and we keep the job site clean and organized throughout.
We know schedules shift, so we keep booking flexible. Whether the job is a quick repair or a full-day installation, we work around your availability and keep you informed at every step.
We have been working in Reading and Berks County since 2012, and older housing stock is a regular part of our work. We have handled knob-and-tube wiring, aluminum branch wiring, and outdated panel configurations across the city and surrounding townships. That experience means we know what to look for and how to address it safely.
We work with homeowners, landlords, property managers, and small businesses throughout Reading and Berks County. Whether the job is a single-family home, a multi-unit rental, or a commercial space, we approach it the same way: diagnose accurately, fix it properly, and leave it code-compliant.
We are available every day from 6:00 AM to 9:30 PM. If you have an urgent electrical issue outside standard business hours, call (484) 926-6495 and we will work to get someone out as quickly as possible.
We provide a clear quote before any work begins, and we do not start until you have approved it. If a diagnostic uncovers something that changes the scope, we explain it and get your sign-off before we proceed. What we quote is what you pay.
All work is performed by licensed electricians who are part of our local team. The people you speak with and the people who show up at your door are the same operation. We are a locally owned business, and that accountability runs through every job we take on.
We keep work areas organized and take care around finished surfaces, especially when running new wiring or opening walls. We clean up before we leave and do not treat your home as a job site to be left in disarray. The goal is to leave the property in better shape than we found it.

We handle everything from a single tripped breaker to a full panel replacement, from a ceiling fan installation to a whole-home rewiring project. Whatever you need, we are ready to help.
We power your home. We protect your circuits. We earn the call.
From a tripped breaker to a full service upgrade, we handle the electrical work that keeps Reading homes and Berks County businesses running safely. Every job gets a clear quote before work begins, and licensed electricians handle the wiring start to finish. The table below covers what we do, who each service fits best, and what is practical to know before you call.
| Service Type | Scope of Work | When You Need It | Worth Knowing |
|---|---|---|---|
| Ceiling Fan Installation | fan wiring and mounting, switch and dimmer wiring, box replacement for fan-rated support, existing fixture swap-out | homeowners adding ceiling fans to bedrooms, living rooms, or covered porches | A standard light-fixture box is not rated for a ceiling fan. We check the box and replace it if needed so the fan is mounted safely. |
| Electrical Safety Inspections | panel and wiring review, outlet and grounding check, code violation identification, pre-sale and pre-renovation inspections | home buyers, sellers, landlords, or anyone with wiring that has not been inspected in years | An inspection before a sale closes or a renovation starts can surface issues that are cheaper to correct now than after the work is done. |
| Knob-and-Tube & Aluminum Rewiring | knob-and-tube assessment and replacement, aluminum branch wiring correction, AFCI and GFCI breaker installation, full or targeted rewiring to current code | owners of pre-1960 homes with original wiring or 1960s-70s homes with aluminum branch circuits | Berks County has some of the oldest housing stock in the country. Knob-and-tube lacks a ground conductor and was never designed for modern loads. Aluminum wiring loosens over time and raises arcing risk. We replace the affected wiring with modern copper and install updated protection as part of the same job. |
| Dedicated Appliance Circuits | dryer and range circuits, refrigerator and dishwasher circuits, workshop and garage circuits, sump pump and basement circuits | homeowners adding a major appliance or finishing a basement or garage workspace | Large appliances need their own circuit to run safely and efficiently. Sharing a circuit with other loads causes trips and shortens equipment life. |
| Whole-Home Surge Protection | panel-mounted surge protection, appliance and electronics coverage, lightning and utility spike protection, installation during any panel visit | homeowners with sensitive electronics, smart-home devices, or major appliances they want to protect | A panel-mounted surge protector guards every circuit in the home, not just the outlets with plug-in strips. It is a straightforward addition during any panel visit. |
| Code-Correction Wiring | failed inspection repairs, permit and code violation correction, grounding and bonding upgrades, documentation for insurers or buyers | homeowners dealing with a failed inspection, an insurer request, or a code violation flagged during a sale | We do the correction work after an inspection identifies violations. Once the repairs are complete, the work is ready for re-inspection. |
| Outlet & Switch Installation | standard and GFCI outlets, AFCI and USB outlets, dimmer and smart switches, weatherproof outdoor receptacles | homeowners adding outlets, replacing outdated receptacles, or upgrading to GFCI or smart controls | GFCI protection is required by code in kitchens, bathrooms, garages, and outdoor areas. We bring existing outlets up to current standard during the same visit. |
| Electrical Repairs & Troubleshooting | dead outlets and switches, flickering or dimming lights, tripped breakers and blown fuses, tracing wiring faults to the source | any homeowner or tenant dealing with an electrical problem that needs a diagnosis | A proper diagnosis finds the root cause, not just the symptom. We trace the fault before we repair it so the problem does not come back. |
| Lighting Installation | recessed and can lighting, exterior and security fixtures, motion sensor and landscape circuits, under-cabinet and accent lighting | homeowners remodeling, adding outdoor security lighting, or upgrading interior fixtures | Exterior lighting adds both security and curb appeal. We run the circuit, mount the fixture, and test everything before we leave. |
| Backup Generator Installation | transfer switch installation, dedicated generator circuit, utility back-feed protection, panel integration and testing | homeowners and businesses in areas prone to nor'easters, ice storms, or summer outages | Pennsylvania winters and summer storms can knock out power for hours or days. We handle the electrical side of the installation completely, including the transfer switch and circuit, so the generator cannot back-feed the utility line. |
| Basement & Sump-Pump Circuits | dedicated sump pump circuit, basement outlet and lighting circuits, GFCI protection in wet areas, circuit sizing for pump load | homeowners finishing a basement or adding a sump pump in a home without a dedicated circuit | A sump pump on a shared circuit can lose power at the worst moment. A dedicated circuit with GFCI protection keeps the pump running and the basement dry. |
| Electrical Panel UpgradesMost Popular | 200-amp service upgrades, main panel and subpanel replacement, load calculation and sizing, service entrance and meter upgrades | homes with undersized panels, frequent breaker trips, or plans to add large appliances or EV chargers | Older Berks County homes were built for a fraction of the electrical load a modern household puts on a panel. A service upgrade is the right fix when the panel runs warm, breakers trip regularly, or you are adding significant new load. |
| Breaker & Fuse Repair | breaker replacement, fuse panel assessment, circuit reset and testing, overload diagnosis | homes where breakers trip repeatedly or a fuse blows without an obvious cause | A breaker that trips regularly is telling you something. It may be a failing breaker, an overloaded circuit, or a wiring fault that needs correction. |
| Wiring & Circuit Installation | new circuit runs, rewiring targeted areas, code-compliant wire sizing, junction box installation | additions, renovations, workshops, or any space that needs new circuits run from scratch | We size wire and breakers to the actual load, not just the minimum. Proper sizing prevents nuisance trips and reduces heat buildup in the walls. |
| EV Charger Installation | Level 2 charger circuit and installation, 240-volt dedicated circuit, panel capacity check, commercial multi-station installs | EV owners who need faster overnight charging at home or businesses adding employee and customer charging | A standard 120-volt outlet can take days to fully charge a modern EV. A dedicated 240-volt Level 2 circuit handles most vehicles overnight. We check panel capacity first and upgrade if needed. |
How do I know if my panel needs an upgrade?
A few signs point clearly to a panel that has reached its limit. Breakers that trip regularly under normal use, a panel that feels warm to the touch, a fuse box that has not been updated in decades, or a home where you cannot run the dishwasher and microwave at the same time are all signals. If you are planning to add an EV charger, a new appliance, or a home addition, a load calculation will tell you whether the existing panel can carry it. We walk through that with you before any work begins.
What causes breakers to keep tripping?
A breaker trips when the circuit draws more current than it is rated to carry. That can mean too many devices on one circuit, a failing breaker that trips at a lower load than it should, or a wiring fault somewhere on the circuit. It can also mean the circuit was undersized for the load it is being asked to carry. We diagnose the actual cause rather than just resetting the breaker, because a breaker that trips repeatedly is protecting you from something.
Is the electrical work permitted and inspected to code?
Work that requires a permit under local code is pulled and inspected. That includes panel upgrades, service changes, new circuit installations, and rewiring projects. We handle the permit process as part of the job. Code-compliant work protects you when you sell the home and keeps your insurance coverage intact.
Work Performed by Licensed Electricians
Every job, from a single outlet to a full rewire, is handled by licensed electricians who know Berks County housing. We do not cut corners on the basics, because the basics are what keep the work safe.
How do I know if the wiring in an older home is safe?
Homes built before the 1960s often have knob-and-tube wiring, which lacks a ground conductor and was not designed for modern electrical loads. Homes from the 1960s and 1970s sometimes have aluminum branch wiring, which loosens at connections over time and raises the risk of arcing. An electrical safety inspection is the practical first step. We assess what is in the walls, explain what we find, and give you a clear picture of what needs attention and what can wait.
What does an EV charger installation involve?
We start by checking your panel's available capacity. If the panel can support a new 240-volt circuit, we run the dedicated circuit and install the Level 2 charger at the location that works best for your garage or parking area. If the panel is already at capacity, we discuss a service upgrade as part of the same conversation. Most residential installations are completed in a single visit. Businesses adding multiple stations get the same process scaled to the number of chargers needed.
Do I need to be home when the electrician is there?
Someone needs to be present to provide access and answer questions about the work. You do not need to supervise the job, but having an adult available when we arrive and when we finish is helpful. If you have questions about scheduling around a work day or other commitment, we work with you to find a time that fits.
Upfront Quotes With No Surprise Fees
We give you a clear number before we start, and that is the number that sticks. You will know what the job involves and what it costs before we touch anything.
What happens if the inspection turns up problems I did not expect?
We walk you through what we found before any work begins. If a diagnostic or safety inspection surfaces a code violation, a wiring fault, or a panel issue, we explain the options clearly and give you a quote for the correction work. Nothing proceeds without your approval. You will know the scope and the cost before we start.
Why would outlets or switches stop working?
A dead outlet is usually a tripped GFCI somewhere upstream, a loose connection at the device or in the box, or a wiring fault on the circuit. A switch that stops working is often a failed switch, a loose wire, or a problem at the fixture it controls. We trace the issue to its source rather than replacing parts until something works. That approach saves time and gives you a repair that holds.
Experienced With Older and Newer Homes
Reading and Berks County carry some of the oldest housing stock in the country. We have worked in homes with knob-and-tube, aluminum wiring, and panels that have not been touched in decades, and we know what to look for.
What does flickering or dimming light mean?
Occasional flickering when a large appliance starts up is normal. Persistent flickering, dimming that happens without an obvious trigger, or lights that flicker across multiple rooms can point to a loose connection at the panel, a failing breaker, a wiring fault, or a service entrance issue. These are worth having looked at, because loose connections generate heat and can become a fire risk over time.
Can you add a circuit for a workshop, appliance, or sump pump?
Yes. Dedicated circuits for dryers, ranges, refrigerators, workshop equipment, and sump pumps are a regular part of what we do. We run the circuit from the panel, size the wire and breaker to the load, and test the circuit before we leave. If the panel does not have capacity for the new circuit, we discuss a subpanel or service upgrade as part of the same conversation.
How long does a panel upgrade or rewiring project take?
A standard 200-amp panel upgrade is typically a full day of work. Whole-home rewiring takes longer and depends on the size of the home and the condition of the existing wiring. Targeted rewiring of specific areas is faster. We give you a realistic time estimate as part of the quote so you can plan around the job.
Call (484) 926-6495 and tell us what you are dealing with. We will ask a few questions, give you a clear quote, and get the work scheduled.
