Electrical Panel Upgrade & Replacement in North Texas

What Is an Electrical Panel Upgrade?

An electrical panel upgrade — also called a breaker box replacement or service upgrade — is the process of replacing your home's main electrical panel with a larger, safer, code-compliant unit capable of handling your home's current and future power demands.

The electrical panel is the command center of your home's power. Every circuit in your house runs through it. When it's undersized, outdated, or failing, everything downstream suffers — and in the worst cases, it becomes a fire hazard.

S&M Electric handles panel upgrades and replacements for homeowners from West Fort Worth to Weatherford — permitted, code-compliant, and backed by our work guarantee.

9 Signs Your Electrical Panel Needs to Be Replaced

You don't need to be an electrician to spot these warning signs:

Breakers that trip repeatedly under normal household load
Lights that flicker or dim when the AC, dryer, or refrigerator kicks on
A panel that feels warm or hot to the touch — never normal, always a concern
Burning smell near your breaker box — call immediately, do not wait
You still have a fuse box — these predate modern safety standards and are often uninsurable
Your panel is 25+ years old — even panels that "seem fine" degrade internally over time
Rust or corrosion on or inside the panel — moisture and electricity are a dangerous combination
An inspector or insurance company flagged your panel — during a home sale or policy renewal
You're adding a major load — EV charger, hot tub, home addition, or large appliance — and your current panel can't support it

If any of these apply, you don't need to wait for a failure. A free on-site assessment tells you exactly where you stand.

* Federal Pacific and Zinsco Panels — A Special Warning *

Are Federal Pacific panels dangerous?

Yes. Federal Pacific Stab-Lok breakers fail to trip properly more than 60% of the time when overloaded or a short circuit occurs. If your home has a Federal Pacific panel — often flagged during home inspections — it should be replaced. This is not a "monitor it" situation.

What about Zinsco panels?

Zinsco panels, common in homes built between the 1950s and 1970s, have a known design defect where breakers can melt and fuse to the bus bar — meaning they stop functioning as safety devices entirely. If your home was built in this era, have your panel inspected.

What the Job Actually Looks Like

No mystery. No surprises. Here's what to expect when S&M Electric shows up:

Step 1 — Free On-Site Estimate

We assess your current panel, calculate your home's actual load, and tell you exactly what size upgrade you need — and why. No upselling. No guesswork. If you don't need a full replacement, we'll tell you that too.

Step 2 — Permit Pulled, Utility Coordinated

Every panel replacement in Texas requires a permit from the local authority having jurisdiction. We pull it — you don't have to navigate any of that. If your utility provider needs to coordinate a service disconnect, we handle that communication as well.

Step 3 — Code-Compliant Installation

Every panel we install meets current National Electrical Code (NEC) standards and Texas state electrical requirements. Your job is signed off by a TECL-licensed electrician (TECL# 40674) — that's your guarantee of compliance.

Step 3 — Clean Worksite, Same-Day Power

We protect your home, remove all debris, and restore your power the same day in the majority of cases. Before we leave, we walk you through exactly what was done and what changed.

Do You Need 100-Amp, 200-Amp, or 400-Amp Service?

Most modern homes require a 200-amp panel as a baseline. Here's a quick reference:

100-amp — Adequate only for smaller older homes with minimal appliances. No longer sufficient for most households.

200-amp — The current standard for most Fort Worth single-family homes. Supports modern appliances, EV chargers, and HVAC without overload.

400-amp — Recommended for larger homes, homes with multiple EV chargers, whole-home generators, or significant workshop/outbuilding loads.

We calculate the right size for your home during the free estimate — not after we've already started the job.

Electrical Panel FAQs — Answered Straight

How much does an electrical panel upgrade cost in Fort Worth?

A residential panel upgrade in Fort Worth typically costs $1,500 to $4,000. The final price depends on the amperage upgrade required, permit fees, whether utility coordination is needed, and any additional wiring work identified during the assessment. We give you an exact number after the free estimate — not a range to manage expectations.

How long does a panel replacement take?

Most residential panel replacements take 4 to 8 hours. Your power will be off during the work. In the majority of cases, power is restored the same day before we leave.

Will my homeowner's insurance go up after a panel upgrade?

In most cases, a panel upgrade reduces your insurance risk profile — and some insurers require it before they'll write or renew a policy on older homes. Contact your insurance provider after the upgrade; many will request documentation of the permit and inspection, which we provide.

Does a panel upgrade require a permit in Texas?

Typically, yes — and we pull it for you. Any licensed electrician in Texas is required to pull a permit for panel replacement work. If a contractor offers to skip the permit to save money, that is a serious red flag. An unpermitted panel is a liability that affects your home's insurability and resale value.

Can I stay home during the panel replacement?

Yes, though your power will be off for most of the job. We recommend having a plan for temperature (especially important in DFW summers), and ensuring any medical equipment that requires power has a backup plan in place. We'll give you a clear timeline at the start of the job.

What brands of electrical panels do you install?

We install panels from reputable manufacturers including Square D, Siemens, and Eaton — brands known for reliability, safety features, and long-term performance. We do not cut corners on materials.

My home is older — does that change anything?

Older homes in the Fort Worth area often have aluminum wiring, undersized service entrances, or panels that no longer meet current code. We assess all of it during the free estimate so there are no surprises mid-job. In some cases, additional wiring or grounding upgrades are needed — we identify this upfront and price it accordingly.

What happens if I don't upgrade my panel?

An undersized or failing panel is one of the leading causes of residential electrical fires. Beyond the safety risk, an outdated panel can limit your ability to add EV chargers, major appliances, or home additions — and can complicate the sale of your home when an inspector flags it.

Get Your Free Panel Assessment — No Obligation

If your panel is aging, undersized, flagged by an inspector, or simply hasn't been looked at in years — the smartest move is a free, no-obligation estimate from a licensed Fort Worth electrician who will tell you the truth about what you need.
