Why DIY Electrical
Work is Riskier
Than You Think
The satisfaction of a completed home project is real — but not all projects are created equal. Electrical work sits in a category of its own. What looks simple from a YouTube video can create invisible hazards that take months or years to cause a fire, shock, or failed home inspection.

The Training Behind
Every Licensed Electrician
We completely understand the appeal of DIY home projects — they can be rewarding, cost-effective, and give you a real sense of ownership over your home. But electrical work exists in an entirely different category of risk than painting a room or replacing a faucet.
The electricians on our team didn’t just watch a few tutorials. Becoming a licensed journeyman electrician in Texas requires a minimum of 8,000 hours of supervised apprenticeship — roughly four years of on-the-job training — plus classroom coursework and a state licensing exam administered by the Texas Department of Licensing and Regulation (TDLR). Master electricians must go even further.
That depth of training exists for a simple reason: the electrical system in your San Antonio home is genuinely dangerous, and the consequences of a mistake aren’t always immediate. A wire connected incorrectly in your wall today might not cause a problem for six months — right up until it starts a fire at 2 a.m.
Below, we walk through the five most significant risks of DIY electrical work so you can make a truly informed decision before picking up a screwdriver.
What It Takes
The Path to Becoming a Licensed Texas Electrician
-
Apprenticeship Coursework 300–1,000+ hours of classroom instruction covering theory, code, and safety
-
8,000 Hours On-the-Job Training Approximately 4 years of supervised field experience across residential and commercial projects
-
Texas State Licensing Exam Passing a state-administered exam through TDLR covering NEC code and TX regulations
-
Ongoing Continuing Education Texas licensed electricians must maintain CE hours to stay current with code updates
Household Voltage
Can Kill You
Here’s a fact that surprises many homeowners: the static shock you feel touching a doorknob can carry upward of 20,000 volts — yet it doesn’t seriously hurt you. Why? Because voltage without adequate current doesn’t cause significant injury. A standard 110-volt household outlet, by contrast, delivers enough current to cause cardiac arrest, severe burns, and death if handled incorrectly.
The danger isn’t just touching a live wire. Capacitors in appliances can hold a lethal charge long after being unplugged. A “de-energized” circuit can become re-energized unexpectedly if another switch or breaker is operated. Moisture on hands or a concrete floor dramatically lowers your body’s resistance, making even a minor contact far more dangerous.
According to the Electrical Safety Foundation International (ESFI), approximately 400 Americans die from electrocution annually, and thousands more suffer non-fatal electrical injuries — many of which happen in the home during attempted repairs.
Our licensed San Antonio electricians follow strict lockout/tagout procedures, use insulated tools rated for the voltages they’re working with, and test circuits with calibrated meters before touching anything. That protocol comes from years of hands-on training — not a tutorial.
Electrocution Risk
Severity: Critical
- Never assume a circuit is off without testing it
- Wet hands multiply electrocution risk dramatically
- Capacitors retain charge after power is cut
- Licensed pros use insulated, rated tools
Unpermitted Work Creates
Long-Term Problems
San Antonio follows the National Electrical Code (NEC), and most electrical work beyond replacing a fixture requires a permit pulled with the City of San Antonio Development Services Department. Skipping the permit process might feel like a shortcut in the moment, but it creates a paper trail problem that surfaces at the worst possible time — usually when you’re trying to sell your home.
During a real estate transaction, a home inspection will often flag unpermitted electrical work. Buyers can — and do — walk away or negotiate heavily for the cost of bringing the work up to code. In some cases, the city may require the work to be torn out and redone entirely by a licensed contractor, at your expense.
The NEC is updated every three years. What was code-compliant in 2005 may not meet today’s standards. Our electricians stay current with every revision — and we pull all required permits so your work is fully documented and inspectable.
Good Times Electric handles the entire permit and inspection process on your behalf. You’ll never have to navigate the City of San Antonio permitting system yourself — we take care of it so your completed job is 100% above board, documented, and insurable.
Code & Permit Risk
Severity: High
- We pull all required San Antonio permits
- City inspection scheduled and managed by us
- All work documented for future home sale
- Current with 2023 NEC code requirements
Faulty Wiring Can
Smolder For Months
This is the risk that most DIY enthusiasts genuinely don’t consider: an electrical mistake doesn’t always announce itself immediately. A loose wire connection, an undersized wire gauge for the load it’s carrying, or a missed ground can create an arc fault inside your wall — a small, intermittent spark that generates heat over time, slowly charring the surrounding wood framing until a fire ignites.
The NFPA reports that electrical fires account for an estimated 51,000 home fires annually in the United States — causing over 500 deaths, 1,400 injuries, and $1.3 billion in property damage. A significant portion of these fires start in wiring that was improperly installed and had been quietly failing for a long time before igniting.
Arc-Fault Circuit Interrupter (AFCI) breakers are specifically designed to detect the erratic electrical signatures of arcing wires and shut the circuit down before a fire starts. Good Times Electric installs AFCI protection throughout San Antonio homes as part of both new work and safety upgrades.
Our electricians know proper wire gauge selection, correct connector types, minimum bend radii for cables, and how to properly terminate wires at every connection point. These details — invisible inside a finished wall — are exactly what separate a safe installation from a fire risk.
Electrical Fire Risk
Severity: Critical
- Arc faults can smolder inside walls for months
- Wrong wire gauge = heat buildup over time
- AFCI breakers detect and stop arc faults
- We install AFCI protection on all circuits
Your Policy May Not
Cover Unlicensed Work
Most standard homeowner’s insurance policies in Texas contain a clause that allows the insurer to deny claims resulting from work that was performed without a required permit or by an unlicensed contractor. This means that if a fire or electrical damage event is traced back to unpermitted DIY work, you may be left covering the entire loss out of pocket — even if you’ve been faithfully paying premiums for years.
Beyond insurance, consider what happens when you sell your home. Texas real estate law requires sellers to disclose known defects. Unpermitted electrical work is a known defect. Buyers and their inspectors are increasingly sophisticated — and unpermitted work that’s been hiding in a wall for years tends to surface right when you need the closing to go smoothly.
Every job Good Times Electric performs is fully permitted, inspected, and documented. That paper trail protects your insurance coverage, satisfies buyers during resale, and gives you complete peace of mind that the work was done right.
The math is simple: the cost of hiring a licensed electrician is almost always a fraction of what unpermitted work costs you when something goes wrong. Call us for a free, no-obligation quote and see what professional electrical work actually costs in San Antonio — you may be pleasantly surprised.
Insurance & Resale Risk

Jobs That Require a
Licensed Pro in San Antonio
There are some home projects where DIY is perfectly reasonable — painting, landscaping, minor carpentry. Electrical work generally isn’t one of them. Here are the jobs we see San Antonio homeowners most commonly attempt themselves, and why each one should be left to a licensed electrician.
Panel Replacement or Upgrade
Working inside a live electrical panel is extremely dangerous. The main breaker does not de-energize the incoming service wires. This job requires pulling a permit and a licensed electrician every time.
Adding New Circuits or Outlets
Running a new circuit from the panel requires correct wire gauge, proper breaker sizing, and in San Antonio, a permit. Undersized wiring is a leading cause of electrical fires.
EV Charger Installation
A Level 2 EV charger requires a dedicated 240V circuit. Incorrect installation can damage your vehicle, void its warranty, and create a serious shock or fire hazard in your garage.
Rewiring Old or Damaged Wiring
Replacing aluminum wiring, knob-and-tube wiring, or damaged cable behind walls involves working in energized spaces and requires proper splicing techniques and inspectable work.
Outdoor or Underground Electrical
Outdoor circuits must use weatherproof boxes, GFCI protection, and correct burial depth for underground cable. Improper outdoor wiring creates shock and fire risks unique to Texas weather conditions.
GFCI & AFCI Upgrades
While replacing a GFCI outlet looks simple, ensuring the correct load/line wiring orientation and testing downstream protection requires a working knowledge of circuit topology most homeowners don’t have.
