Residential · Franklin County & St. Louis, MO
A professional electrical safety inspection is the fastest way to know exactly what's safe, what's outdated, and what could start a fire in your home's wiring. CAS Electric performs full home electrical inspections across Franklin County and the Greater St. Louis area — Pacific, Washington, Union, Sullivan, St. Clair, Eureka, Wildwood, Villa Ridge, and Marthasville. You get a licensed electrician on-site, a written report with photos, and a clear list of what (if anything) needs attention.
An electrical safety inspection — sometimes called a home electrical audit or electrical inspection — is a top-to-bottom review of every part of your home's electrical system: the service drop and meter, the main panel and any subpanels, grounding and bonding, branch circuits, outlets and switches, GFCI/AFCI protection, smoke and CO detectors, and visible wiring in the attic, basement, and crawlspace. The goal is simple: identify anything that's unsafe, out of code, or about to fail — before it causes damage.
Most Franklin County and St. Louis homeowners call us for an inspection in one of four situations: they're buying or selling a home and want more depth than the general home inspector provided, their insurance carrier flagged the panel at renewal (Federal Pacific Stab-Lok, Zinsco, or Challenger), they're seeing warning signs like flickering lights, warm outlets, or breakers that trip repeatedly, or they simply own an older home (pre-1980) and want peace of mind before adding an EV charger, hot tub, or addition.
CAS Electric is a licensed, insured, owner-operated electrical contractor with 17 years of experience across Missouri residential and commercial work. The electrician who inspects your home is the electrician who would perform any recommended repairs — no upsell handoff, no commission-based sales reps. If your system checks out clean, we'll tell you that in writing and you'll walk away with a documented safety report you can hand to an insurer, a buyer, or your real estate agent.
Every inspection follows the current National Electrical Code (NEC) plus the local amendments used by Franklin County, St. Louis County, and each municipal jurisdiction we work in. We check for the code items that most commonly show up as insurance or resale issues: proper grounding electrode conductor and bonding, GFCI protection in kitchens/baths/garages/exterior/basements, AFCI protection in bedrooms and living areas, proper working clearance around the panel, tamper-resistant receptacles, and correct wire sizing and overcurrent protection.
Electrical safety inspection pricing depends on home size, number of panels, and access. Point-of-sale inspections and insurance re-certifications are quoted flat before the visit — no hourly meter. We provide a free written estimate.
Call or request a quote online. Most whole-home electrical safety inspections take 1.5–3 hours depending on home size and panel complexity. We give you a flat price up front.
We check the service drop or lateral, meter base, service entrance conductors, grounding electrode(s), and exterior receptacles/lighting for damage, corrosion, and code compliance.
We open every panel to inspect the bus, breakers, neutral/ground bonding, torque on lugs, breaker/wire size match, double-tapped breakers, and any signs of arcing or overheating.
We test outlets for correct polarity, ground, and GFCI/AFCI operation; check junction boxes, switches, hardwired appliances, smoke/CO detectors, and visible attic/basement/crawlspace wiring.
You get a documented report with what's safe, what's borderline, and what needs attention — prioritized so you know what's urgent vs. eventual. Usable for insurance, resale, or lender requests.
A CAS Electric home electrical safety inspection covers the service drop and meter, main panel and subpanels, grounding and bonding, breaker sizing and condition, branch circuits, every accessible outlet and switch, GFCI/AFCI protection, smoke and CO detectors, and visible wiring in the attic, basement, and crawlspace. You get a written report with photos and a prioritized list of any issues found.
Inspection cost depends on home size and how many panels are involved. We quote a flat rate before the visit so there's no hourly surprise. Point-of-sale and insurance re-certification inspections are also flat-priced. Contact us for a free written estimate.
For most homes, every 8–10 years is a reasonable interval. Older homes (pre-1980), homes with aluminum branch wiring, homes with Federal Pacific/Zinsco/Challenger panels, or homes about to be sold or purchased should be inspected sooner. Any home should be inspected after a major electrical event — a lightning strike, a flood, a fire, or a partial power loss.
In Missouri the inspection should be done by a licensed electrical contractor — not a general home inspector. General home inspectors are qualified to flag visible issues, but they can't open panels, torque-check lugs, or evaluate code compliance the way a licensed electrician can. CAS Electric is fully licensed and insured for both residential and commercial electrical inspection work.
It's not required by law in Missouri, but it's strongly recommended for homes built before 1980, homes with visible panel issues, or homes where the general home inspection flagged electrical concerns. A licensed electrical inspection gives you (or the buyer) a documented, actionable list — and can be used to negotiate credits or repairs before closing.
Yes. Insurance carriers most commonly flag Federal Pacific (Stab-Lok), Zinsco/Sylvania, and Challenger panels, plus knob-and-tube and ungrounded aluminum branch wiring. We inspect the system, document what's present, and either provide a written safety certification or recommend the specific repair or panel replacement needed to satisfy the carrier.
Yes — CAS Electric performs commercial electrical inspections for landlords, tenant-finish projects, warehouse and shop buildings, and small-office spaces across Franklin County and Greater St. Louis. Commercial inspections include the service, main and subpanel breakdown, distribution equipment, emergency lighting, and life-safety circuits.
Call for an inspection if you see any of the following: breakers that trip repeatedly on the same circuit, flickering or dimming lights, warm or discolored outlets or switches plates, a burning smell near an outlet or panel, sparking when plugging in, a two-prong (ungrounded) outlet where you need a three-prong, or visible aluminum branch wiring. Any of those are safety concerns and should not wait.
