Electrical Safety Tips Every Denver Homeowner Should Know
Electrical safety isn’t something most homeowners think about until something goes wrong. But in the Denver metro area — where aging homes in Centennial, Aurora, Englewood, and Littleton are common — electrical hazards are more frequent than you might expect. The good news: most electrical safety issues are easy to prevent with a little awareness and the right habits. Here’s what every Denver homeowner should know to keep their family safe and their home protected.
Test Your GFCI Outlets Every Month
GFCI (Ground Fault Circuit Interrupter) outlets are the ones with the TEST and RESET buttons — required by code in kitchens, bathrooms, garages, and outdoor areas. They’re designed to cut power instantly if they detect a dangerous current leak, preventing electrocution. Test yours monthly by pressing the TEST button — it should cut power to that outlet. Press RESET to restore it. If an outlet doesn’t respond or won’t reset, it’s failed and needs to be replaced. Mallard Electric can replace faulty GFCI outlets quickly and make sure all the right areas of your home have them.
Don’t Overload Circuits or Extension Cords
One of the most common causes of residential electrical fires is overloaded circuits. Plugging too many high-draw appliances into one circuit — think space heaters, hair dryers, and air fryers — trips breakers at best and starts fires at worst. Extension cords are meant to be temporary, not permanent solutions. Using them long-term, especially with high-wattage appliances, is a fire hazard. If you find yourself relying on power strips or extension cords throughout your home, the real fix is adding dedicated circuits or more outlets. Mallard Electric can add circuits exactly where you need them — in your kitchen, home office, garage, or anywhere else.
Know the Warning Signs of Faulty Wiring
Faulty wiring is responsible for thousands of house fires every year nationwide. The problem is it’s often hidden inside walls where you can’t see it. But there are warning signs you can spot: outlets or switches that feel warm to the touch, lights that flicker or dim for no reason, a burning smell anywhere near outlets or your electrical panel, outlets with scorch marks or discoloration, or breakers that trip repeatedly on the same circuit. Any one of these is a reason to call a licensed electrician immediately. In older Denver metro homes — especially those built before 1980 — aluminum wiring or knob-and-tube wiring can be present, both of which carry significant safety risks. If your home was built in that era and hasn’t been inspected recently, it’s worth scheduling an electrical safety check.
Keep Your Electrical Panel Clear and Accessible
Your electrical panel needs to be accessible at all times — never store boxes, shelving, or anything else blocking it. In an emergency, you need to reach it fast to shut off power. Electrical code actually requires 36 inches of clear space in front of the panel. Also make sure each breaker in your panel is clearly labeled so anyone in the household can identify and shut off a specific circuit quickly. Unlabeled or mislabeled breakers are more than just annoying — they’re a real safety problem in emergencies. If your panel labels are outdated or missing, Mallard Electric can do a proper panel audit and labeling as part of any service call.
Install Whole-Home Surge Protection
Colorado’s afternoon thunderstorms are among the most frequent in the country, and every lightning strike nearby can send a power surge through your home’s electrical system. A single surge can destroy your refrigerator, HVAC system, smart TV, computers, and other expensive appliances in seconds. Power strip surge protectors help at the outlet level, but the real protection comes from a whole-home surge protector installed at your main panel. One device protects every outlet, appliance, and circuit in the home simultaneously. It’s a one-time installation — typically under $300 including labor — that can save thousands in appliance replacement costs. It’s one of the smartest electrical upgrades any Denver metro homeowner can make.
Childproof Your Outlets If You Have Young Kids
Plastic outlet covers are better than nothing, but they’re easy for curious toddlers to remove. The safest solution is tamper-resistant outlets (TRRs), which are now required by the National Electrical Code in all new construction. TRRs have built-in spring-loaded shutters that only open when equal pressure is applied to both slots simultaneously — exactly what a plug does, but not what a child’s finger or a bobby pin does. Replacing standard outlets with tamper-resistant ones throughout your home is an inexpensive upgrade that provides real, lasting protection. If you have young children at home, it’s one of the best electrical investments you can make.
Know When to Call a Licensed Electrician — and When Not to DIY
Some electrical tasks are reasonable for a handy homeowner — replacing a light switch, swapping out a light fixture, or installing a ceiling fan where wiring already exists. But anything that involves your electrical panel, new circuit runs, adding outlets to walls, or diagnosing mysterious electrical problems should always be handled by a licensed electrician. In Colorado, unlicensed electrical work can void your homeowner’s insurance, fail a home inspection, and — most critically — create hazards that put your family at risk. The permit process exists for good reason: it ensures the work is done correctly and inspected by a professional. If you’re ever in doubt, call Mallard Electric for a free consultation before you start any project. We’re happy to tell you exactly what’s safe to DIY and what needs a licensed electrician.
