Electricians Who Know Arnold Homes

When something goes wrong with the electrical system in your Arnold home, you want an electrician who answers the phone and shows up when they say they will. Exceptional Electric has served Jefferson County and the greater St. Louis area since 2004, and our Arnold shop sits right on Telegraph Road — Arnold hasn’t been a service area to us so much as a home base.

Arnold’s housing mix runs from the ranches and split-levels that went up along Jeffco Boulevard and Richardson Road decades ago to the newer construction filling out the subdivisions south of I-55. Older homes tend to hide the same headaches — undersized panels, aluminum branch wiring, ungrounded two-prong outlets — while newer households are adding load the original builder never planned for, like EV chargers and hot tubs. And running underneath all of it is something no other city we serve has to think about the same way: the river.

Water and Your Electrical System: What Arnold Homeowners Should Know

Arnold sits where the Meramec meets the Mississippi, with the river forming the city’s northern and eastern edge. In 1993 the Meramec crested around 45 feet and damaged more than 225 properties here. What Arnold did next became a model for the rest of the country — a voluntary buyout program, starting with federal hazard mitigation money in 1994, that eventually acquired roughly 500 homes and let that land go back to wetland.

It worked. Today’s Arnold is far less exposed than 1993’s Arnold was, and the wetlands do real work absorbing high water. But the river hasn’t retired: the December 2015 crest hit 47.26 feet, higher than 1993. And a basement doesn’t need a hundred-year flood to take on water — a bad storm, a failed sump, or a saturated water table will do it.

Which makes two things worth understanding, because most homeowners learn them the expensive way.

If it went under water, it gets replaced — not dried out

This is the one that costs people money, and it’s counterintuitive enough that it’s worth being blunt about: electrical equipment that has been submerged should be replaced, not dried and put back into service. That’s not a contractor upselling you. It’s the industry’s standard guidance, and it applies to panels, circuit breakers, fuses, receptacles, switches, GFCIs, and AFCIs alike.

The reason is that the damage is invisible. Floodwater isn’t clean water — it carries silt, sewage, and dissolved contaminants that get inside sealed devices and stay there. As things dry, those contaminants corrode contacts and gum up the mechanical linkages that make a breaker trip. The panel looks fine. The lights come on. And the breaker that’s supposed to save your house during a fault has a mechanism that’s quietly seized. It fails silently, and you find out during the one event it existed to prevent.

Circuit breakers are the sharpest example, because a breaker is a mechanical device pretending to be a solid-state one. It has springs and a bimetallic strip inside. Silt in that assembly doesn’t announce itself. If your panel took on water, the honest answer is that it’s finished, regardless of how it looks — and the warning signs a failing breaker gives you are worth knowing even if your basement has stayed dry.

If you’re dealing with water damage, an electrical safety inspection documents exactly what was affected and what has to go. That documentation matters for your insurer, and it matters for getting your power turned back on.

Your sump pump is the most important circuit in your house

Almost nobody treats it that way, and that’s the problem.

Think about how the failure actually plays out in Arnold. A storm rolls through. The water table comes up, the sump kicks on, and at the exact moment it matters most, the power goes out — because the same storm that filled your sump took down the line. Or the pump is sharing a circuit with the freezer and a dehumidifier and the breaker trips at 2 a.m. with nobody awake to hear it. Or it’s plugged into a GFCI that nuisance-tripped three weeks ago and nobody noticed, because a tripped GFCI in an unfinished basement is completely silent.

Every one of those is an electrical problem, not a plumbing problem. And every one is preventable:

• A dedicated circuit. The sump shares with nothing. Nothing else can trip it, and nothing else’s fault can take it down.
• Correct GFCI handling. Current code requires GFCI protection for basement receptacles, and that protection is genuinely a good idea around a wet sump pit — but it has to be installed where you’ll actually notice a trip, not buried behind a shelf.
• Battery backup, or a standby generator. A generator sized to carry the sump means the storm that knocks out your power doesn’t also fill your basement. In Arnold, that’s not a luxury item — it’s the whole reason to own one.

We’ll walk your basement, look at what the sump is actually connected to, and tell you what it would take to make that circuit dependable. It’s a small job that prevents a very large one.

Aluminum Wiring: Arnold’s 1960s and ’70s Legacy

Arnold grew up fast in the late 1960s and early ’70s — which is unfortunate timing, because that’s precisely the window when copper prices pushed builders to wire homes with aluminum branch circuits.

Aluminum isn’t a bad conductor. The trouble is at the connections. Aluminum expands and contracts more than copper as circuits heat and cool, so over decades the connections at your outlets and switches work themselves loose. It also oxidizes, and unlike copper oxide, aluminum oxide doesn’t conduct — so resistance climbs at the joint, which makes it hotter, which loosens it further. It’s a feedback loop that runs for thirty years behind a wall plate. The U.S. Consumer Product Safety Commission has found that homes wired with aluminum branch circuits before 1972 are far more likely to have connections reach fire-hazard conditions than comparable homes wired in copper.

Here’s what Arnold homeowners should know: this is a fixable problem, and you almost certainly don’t need to rewire the house. The connections are the issue, not the wire in the walls. There are approved repair methods that treat each connection properly — and there are shortcuts that don’t. Simply twisting aluminum and copper together under a standard wire nut is a common, cheap “fix” that isn’t recognized as a permanent repair, and it can leave you worse off than before, because now you believe it’s handled.

If you have aluminum branch wiring — warm wall plates, flickering that comes and goes, a faint smell of hot plastic near an outlet, or just a house built in the right years — get it looked at. We’ll tell you what you have and what the real options are.

Electrical Services We Provide in Arnold

Whatever the electrical need, there’s a good chance we handle it. Our Arnold customers call us most often for:

• Electrical Panel Upgrades & Replacement — If your Arnold home still runs on a 100-amp panel or a brand with a known safety history, upgrading to 200 amps clears the way for modern appliances and gives you room to grow.
• Electrical Wiring & Rewiring — New circuits, troubleshooting, aluminum connection repair, and full rewires for older Arnold homes with wiring that’s no longer up to code.
• Breaker & Fuse Repair — Breakers that trip for no clear reason usually point to a real problem underneath. We find the cause instead of just resetting it.
• Outlet & Circuit Installation — GFCI outlets for kitchens, baths, and basements, dedicated circuits for sump pumps and home offices, and repairs for outlets that have quit.
• Home Generator Installation — Standby generators sized to your home’s real load, including the circuits that actually matter when the power goes out.
• Whole-Home Surge Protection — Missouri storms are hard on electronics. A panel-mounted surge protector guards everything downstream.
• Grounding Corrections — Ungrounded two-prong outlets are common in Arnold’s older homes. We add proper grounding or code-approved protection so your circuits are what they appear to be.
• EV Charger Installation — Level 2 home charging installed cleanly, sized to your vehicle and your panel’s available capacity.
• Ceiling Fans & Lighting — Fixture swaps, recessed lighting, LED upgrades, and fans installed and balanced right.
• Code Corrections — Inspection report flagged open junctions, missing grounds, or unprotected circuits? We correct the items and document the work.
• Electrical Safety Inspections — Buying, selling, recovering from water, or just want a professional read on an older home? We’ll inspect the system and give you a clear report.

Running a business in Arnold? We also handle commercial electrical work and tenant finish-outs for the offices and retail spaces along Jeffco Boulevard, Telegraph Road, and the surrounding commercial corridors.

Permits and Inspections in Arnold

Panel upgrades, service changes, rewires, and new circuits require a permit and an inspection before the utility will reconnect. After water damage, that inspection isn’t a formality — it’s the gate between you and having power again, and it’s the reason “we dried the panel out” is not a plan.

We pull the permit, schedule the inspection, and coordinate the reconnect. You don’t file anything and you don’t spend a day waiting on hold. If a previous owner did unpermitted work that surfaces mid-project, we’ll tell you plainly what it means before it becomes a surprise.

Why Arnold Homeowners Call Exceptional Electric

We’re based here. Our Arnold shop is on Telegraph Road. When we say we know the local housing stock, we mean we’ve been driving past it every morning since 2004.

Two decades in Jefferson County. We’ve worked in Arnold neighborhoods long enough to know the quirks that come with them — the aluminum years, the panel brands, what water does to a basement. That experience means faster diagnosis and fewer surprises on your invoice.

Licensed, and it shows in the work. Our master and journeyman electricians handle the complex jobs — service upgrades, code corrections, new circuits — that shouldn’t go to a handyman.

Upfront, per-item pricing. You approve the price before we start. No hourly meter running while you watch the clock.

Highly rated by our neighbors. Hundreds of St. Louis-area homeowners have reviewed us, and the reviews keep coming back to the same things: on time, clean work, and technicians who explain what they’re doing.

Financing available. Bigger projects like a panel replacement or generator install don’t have to wait. We offer financing through Wisetack so you can move forward on your timeline.

Serving All of Arnold and Jefferson County

We cover Arnold end to end — from the neighborhoods near Arnold City Park to the newer developments off Highway 141, the corridor along Jeffco Boulevard and Richardson Road, and the homes out toward the Meramec bottoms.

Arnold is also our base for the rest of Jefferson County. We regularly serve Imperial, Barnhart, Pevely, High Ridge, and House Springs, along with Fenton, Oakville, and Mehlville just across the county line. If you’re just outside city limits, call anyway — you’re probably still in our range.

Frequently Asked Questions

Do you offer emergency electrical service in Arnold?

Yes. Burning smells, warm outlets, sparking panels, and sudden loss of power get priority dispatch — we hold openings in the daily schedule specifically for them. Call (636) 296-7789 and tell the office what you’re seeing, and we’ll get a technician to your Arnold home as quickly as possible. If you smell burning or see smoke, shut off the main breaker if you can safely reach it and call the fire department first. Never wade into standing water to reach a panel.

My basement flooded. Can the panel be dried out and reused?

No — and this is worth being direct about. Electrical equipment that has been submerged should be replaced, not dried and returned to service. That covers panels, breakers, fuses, receptacles, switches, and GFCIs. Floodwater carries silt and contaminants that get inside sealed devices and corrode the contacts and mechanical linkages as they dry. The equipment can look and behave completely normal while a breaker’s trip mechanism is quietly seized — and you’d only discover it during the fault it was supposed to interrupt. If your basement took on water above the level of any electrical equipment, have it inspected before you reconnect anything.

My Arnold home has aluminum wiring. Do I need to rewire the whole house?

Almost certainly not. With aluminum branch wiring, the problem is at the connections rather than in the wire itself, so the fix targets each connection rather than replacing everything behind the walls. What matters is that it’s done with an approved method — twisting aluminum and copper together under an ordinary wire nut is a common shortcut that isn’t recognized as a permanent repair and can leave you with a false sense of security. We’ll assess what you have and lay out the real options and what each costs.

Should my sump pump have its own circuit?

Yes, and in Arnold we’d call it one of the better small investments you can make. On a shared circuit, anything else on that circuit can trip the breaker and take your sump down with it — usually at night, during the storm, with nobody awake to notice. A dedicated circuit removes that entire category of failure. If you want the sump to survive an outage as well as a trip, that’s a battery backup or a standby generator sized to carry it.

How much does it cost to upgrade an electrical panel in Arnold?

Cost depends on your current setup, the amperage you’re moving to, and whether the meter and service entrance need work. We give you a firm, itemized quote before any work begins, so you’ll know the full price up front.

My older Arnold home has two-prong outlets. Is that a problem?

Ungrounded two-prong outlets are common in Arnold’s older homes and can be a safety and code issue, especially near water. Where a ground path isn’t available, code permits replacing them with GFCI-protected three-prong outlets, labeled to show there’s no equipment ground — that gives you shock protection without rewiring the house. It’s an honest interim step, though: surge protectors still won’t function properly without a real ground. We’ll tell you which rooms genuinely need rewiring and which are fine with GFCI protection.

Do you install EV chargers?

Yes. We install Level 2 home chargers and run a load calculation to confirm your panel has the capacity to support one before we begin — an important step in older homes running smaller service.

Are your electricians licensed?

Yes. Every job is performed or supervised by licensed electricians, and our master and journeyman electricians handle all panel, service, and code work. We pull the permits ourselves.

Can you help with financing?

We can. Through our financing partner, Wisetack, you can spread the cost of larger projects over time. Ask us about it when you schedule.
