Home Electrical Upgrades & Improvements Services in Marshall, TX
Many homes in Marshall, TX and across Harrison County were built decades before modern appliances, central HVAC systems, and home offices became the standard. Older panels rated at 60 or 100 amps were designed for a simpler time. If your breakers trip when the AC kicks on, your outlets are ungrounded two-prong, or your lights dim when you run the microwave, your electrical system is not keeping up.
At Shilowe Electric and Data LLC, we handle home electrical upgrades and improvements for homeowners across Marshall, Longview, Hallsville, Gladewater, Jefferson, Kilgore, and the surrounding East Texas area. Every job is completed by a licensed, insured electrician and brought to current National Electrical Code (NEC) standards. We are guided by faith and driven by quality — that means honest work, upfront pricing, and no shortcuts.

Signs Your Marshall Home Needs an Electrical Upgrade
Most homeowners do not know their electrical system is outdated until a problem shows up. These are the warning signs we see most often in homes across Harrison County:
- Breakers that trip regularly, especially when running the AC, dryer, or multiple appliances at once
- Lights that flicker or dim throughout the house
- Outlets that only have two prongs, feel warm, or show scorch marks
- A fuse box still in place rather than a modern breaker panel
- No GFCI-protected outlets in the kitchen, bathrooms, garage, or outdoors
- You are planning a kitchen or bathroom remodel, a room addition, or want to add a smart home system
- Your panel is over 20 years old and has not been inspected recently
If any of these match your home, a consultation with our team can tell you exactly what needs to be done and what it will cost before any work begins.
What Home Electrical Upgrades Services We Handle in Marshall, TX
Electrical Panel Upgrades and Breaker Replacements
Most older Marshall homes run on 60 or 100-amp panels that cannot handle today's AC units, dryers, and appliances. We replace outdated panels, swap failing breakers, and coordinate any required Oncor shutoff. All work is done to NEC standards.
GFCI and AFCI Outlet Upgrades
Texas NEC code requires GFCI protection near water sources and AFCI protection in living areas. Many older Harrison County homes are missing both. We install the correct outlets in the correct locations so your home is code-compliant and your family is protected.
Dedicated Circuits for Appliances
Dryers, refrigerators, microwaves, and HVAC units need their own circuit. Running them on shared circuits is why breakers keep tripping. We install dedicated circuits for any high-draw appliance or equipment that needs clean, uninterrupted power.
Lighting Upgrades and Fixture Installation
We install recessed lighting, under-cabinet lights, bathroom fixtures, and exterior security lighting. Circuits are run correctly and boxes are properly rated — no flickering, no overheating.
Outlet and Switch Upgrades
We replace two-prong ungrounded outlets with modern three-prong versions, add USB-integrated outlets, and swap out worn switches and dimmers throughout the home.
Whole-Home Surge Protection
East Texas storms and Oncor grid events can damage your electronics in seconds. A whole-home surge protector at the panel stops surges before they reach your devices. We install it as a standalone service or alongside any panel job.

Frequently Asked Questions: Home Electrical Upgrades in Marshall, TX
What home electrical upgrades are most common in Marshall, TX?
The most common upgrades we handle in Harrison County homes are panel replacements from 100-amp to 200-amp service, GFCI outlet installation in kitchens and bathrooms, dedicated circuit additions for new appliances, and whole-home surge protection. Homes built before 1990 often need several of these at the same time.
Do I need a permit for electrical upgrades in Marshall, TX?
Yes. Panel replacements, new circuit installations, and most wiring work requires a permit from the City of Marshall or Harrison County, along with a follow-up inspection. We pull the permit before any work begins and coordinate the inspection as part of the job. You receive the documentation after completion.
How do I know if my panel needs to be replaced or just repaired?
If your panel is tripping breakers regularly under normal loads, feels warm to the touch, has scorch marks, or is still a fuse box, replacement is almost always the right answer. Panels that are 20 or more years old should be inspected. Shilowe Electric can assess your panel and tell you clearly whether a repair handles the issue or whether a full replacement is needed.
What is the difference between GFCI and AFCI outlets?
GFCI outlets protect against electrical shock by shutting off power when a ground fault is detected. They are required near water sources. AFCI breakers or outlets protect against arc faults, which are a leading cause of house fires. Texas follows the NEC, which requires both in specific locations depending on when the work was done and where the outlets are located. We install both correctly and explain what is required versus what is recommended.
How long does a panel upgrade take?
Most panel replacements are completed in a single day. The power to your home is off for a portion of that time while the new panel is installed and connected. We coordinate the Oncor shutoff in advance so the outage window is as short as possible.
Is it safe to keep living in my home during an electrical upgrade?
Yes in most cases. Panel upgrades require a temporary shutoff for a few hours. Outlet and circuit work is done one area at a time. We keep disruption to a minimum and communicate clearly so you know what to expect before we arrive.
Can you add outlets to an older home in Marshall?
Yes. Adding outlets to older Harrison County homes is one of the most common jobs we take on. We assess your panel’s available capacity, run new wiring through the walls, and install the outlets to current code. Many older Marshall homes have two-prong ungrounded outlets that no longer meet NEC standards. Upgrading them is a smart move before any renovation.
What should I do if I smell burning from an outlet or panel?
Shut off the circuit breaker for that area immediately and do not use the outlet. A burning smell from an outlet or panel can signal overheating wires, a loose connection, or an arcing fault, all of which are fire hazards. Call a licensed electrician the same day. Do not open the outlet box or panel cover yourself.
