St. Louis, MO, homeowners face some of the region’s most damaging severe weather every year, and a residential electrician can help you protect your home’s electrical system before and after a storm. From spring supercell thunderstorms to winter ice storms that snap overhead lines and knock out power for days, the metro area’s weather patterns create real, recurring electrical hazards. This guide covers surge protection, post-storm safety steps, backup power basics, and the critical question every homeowner asks after a major outage: who do you call first?
How St. Louis Storms Put Your Home’s Electrical System at Risk
Severe weather stresses every part of your home’s electrical system. St. Louis sees roughly 45 thunderstorm days per year, with wind gusts regularly exceeding 60 mph. In winter, ice storms have a long history of downing lines and causing widespread outages across St. Louis City, St. Louis County, St. Charles, and Jefferson County. North St. Louis County has repeatedly been identified as one of the hardest-hit areas during major storm events, partly because of mature tree cover over older overhead service lines.
Older homes in neighborhoods like Dogtown, The Hill, Bevo Mill, and the north side carry additional risk. Many were built with wiring and panels sized for a much smaller electrical load. When a storm surges power through the grid or when the utility restores power after an outage, aging infrastructure may not absorb the spike as well as a modern panel. A licensed electrician can assess whether your panel and wiring are up to the demands St. Louis weather routinely places on them.
Do I Need Whole-Home Surge Protection?
Do I Need Whole-Home Surge Protection?
Whole-home surge protection is worth serious consideration for most St. Louis homeowners. A panel-mounted surge protective device intercepts large voltage spikes at the source before they spread through your circuits, protecting hardwired equipment like your HVAC system, refrigerator, and smart appliances. Plug-in surge strips only guard whatever is physically connected to them and may not handle a large lightning-related surge effectively.
The recommended approach uses both layers. A whole-home device mounts at the panel and handles large incoming surges. Plug-in strips near computers, televisions, and other sensitive electronics add a second line of defense against smaller residual spikes. During an active storm, unplugging high-value electronics is still a smart step. Installation of a panel-level surge protector is a job for a licensed electrician because the connections carry live voltage even when breakers are off.

After the Storm: Safe Steps Before You Touch the Panel
Do not re-enter your home or touch any electrical component until you have checked for visible hazards. Here is a safe sequence to follow after a significant storm:
- Stay away from any downed power line and call Ameren Missouri immediately at 800-552-7583 to report it.
- From a safe distance, look at your meter, service mast, and weatherhead for visible damage such as broken conduit, pulled wires, or a leaning mast.
- If water has entered your home and reached outlets, the panel, or any wiring, do not touch the electrical system. Call a licensed electrician before restoring power.
- Check your breaker panel for tripped breakers. If a breaker has tripped, flip it firmly to off, then back to on, and repeat three times to fully reset it. If it will not hold or trips again immediately, do not force it.
- If you smell burning, see scorch marks near the panel, or hear buzzing from outlets or the panel, turn off the main breaker if it is safe to do so and call for a professional inspection.
Is It Safe to Use My Electrical Panel After Flooding or Storm Damage?
No. A flooded or water-exposed panel should not be used until a licensed electrician has inspected it. Moisture inside breakers, on the bus bars, or along wiring can cause shorts, arcing, or fires that may not appear immediately. This is true even if the water has dried before you return home. An electrician will evaluate whether components need to be dried, tested, or fully replaced before power is safely restored.
Ameren or an Electrician? Who to Call and When
Ameren Missouri owns and is responsible for the lines running to your home and the utility side of the meter. An electrician handles everything on the home’s side.
Ameren handles: The overhead utility lines, the transformer, and the service drop running from the utility pole to your home’s weatherhead connection point.
A residential electrician handles: The service mast and weatherhead, the meter base, the entrance cable running from the weatherhead into the panel, the main panel itself, and all interior wiring and circuits.
If your service mast has been bent or broken by a fallen tree branch, that is your responsibility, not Ameren’s. Ameren will not reconnect service until a licensed electrician has repaired the homeowner’s side of the connection and, in many cases, until an inspection has been completed. You can review a detailed breakdown on the electrical repairs after storm damage page.
Generators and Backup Power: Doing It Safely
A portable generator can keep critical appliances running during a multi-day outage. Safe use depends on two non-negotiable rules: keep it outdoors and never connect it directly to a wall outlet.
Portable generators produce carbon monoxide, a colorless, odorless gas that is deadly at high concentrations. Always operate a generator at least 20 feet from the home with the exhaust pointed away from doors, windows, and vents. Never run one in a garage, even with the door open. Install battery-powered carbon monoxide detectors on every level of your home and test them before storm season arrives.
Plugging a generator into a household outlet without a proper transfer switch is called backfeeding. It can send dangerous voltage back into utility lines where Ameren crews may be working, and it is illegal. The safe, code-compliant solution is a power inlet box and a manual transfer switch installed by a licensed residential electrician. A transfer switch isolates your home from the grid so only one power source energizes your circuits at a time. Local electricians familiar with St. Louis, MO, permit requirements can size and install this equipment correctly.
