Why Does My House Smell Like Fish? Dealing with Electrical Issues in Casselberry
You’re sitting in your living room in Secret Lake, finally relaxing after a long week, when you catch a whiff of something strange. It’s not dinner, and it’s not the trash. It smells distinctly… fishy. If you haven’t cooked seafood recently, that smell isn't just a nuisance; it’s a serious warning sign. Electrical contractors in Casselberry, Florida, know that a fishy odor is often the first indicator of overheating electrical components before they spark a fire.
Ignoring this smell can lead to dangerous consequences. Overheating plastic insulation on wires releases chemicals that mimic the scent of fish or urine. It’s your home’s way of screaming for help. At Spectrum Electric, we've seen firsthand how quickly a small melting wire can turn into a major emergency. This guide explains why that smell happens, why you shouldn't ignore it, and how a professional can fix it safely.
What Causes That "Fishy" Smell?
That distinct fishy odor comes from the heat-resistant chemicals used in the plastic insulation of electrical wires and components. When these plastics overheat or melt, they release a gas that smells like fish or urine. It’s not rotting food; it’s burning plastic.
The danger here is imminent. If the plastic is melting, the heat source is already critical. This usually means an electrical connection is loose, arcing, or overloaded. According to the National Fire Protection Association (NFPA), electrical failures or malfunctions were the second leading cause of U.S. home fires between 2015 and 2019, accounting for 13% of home structure fires [1].
In Casselberry homes, especially older properties near Lake Howell with original wiring, this is a common issue. The smell tends to drift. It might be strongest near a specific outlet, switch, or even coming from the air conditioning vents. If you smell it, don't try to mask it with air freshener. You need to find the source.
Common Culprits Behind Electrical Odors
Identifying exactly what is overheating can be tricky for a homeowner, but there are three usual suspects we see most often in Central Florida homes.
Overloaded Circuits
We put a lot of demand on our electrical systems today. Between high-powered gaming PCs, large HVAC units fighting the humidity, and modern kitchen appliances, circuits can easily get overwhelmed. When a circuit draws more current than it can handle, the wires heat up. If the breaker doesn't trip immediately (or if it's an old, faulty breaker), that heat melts the insulation.
Failing Electrical Components
Everything wears out eventually. In older Casselberry neighborhoods, we often find outlets and switches that have simply reached the end of their lifespan. Connections inside the wall become loose over time due to thermal expansion and contraction—basically, the wires expanding in the heat and shrinking in the cool AC. A loose connection creates resistance, resistance creates heat, and heat creates that fishy smell.
Malfunctioning Appliances
Sometimes the issue isn't inside the walls, but plugged into them. An old dishwasher, dryer, or refrigerator with a failing motor can draw too much power or have internal shorts. If the smell is localized strictly around one appliance, unplug it immediately.
Why You Need Electrical Contractors in Casselberry
You might be tempted to hop on YouTube and try to fix this yourself. Please don't. Electrical repair is dangerous, and "fishy smell" calls are often complex.
The Dangers of DIY
Unlike painting a wall or fixing a leaky faucet, electrical mistakes can be fatal or cause property loss. If you don't tighten a wire correctly, it arcs. If you use the wrong gauge wire, it overheats. Even turning off the breaker might not cut power to the exact wire you're touching if the home's wiring is messy.
Professional expertise and tools
Licensed contractors like Spectrum Electric use thermal imaging cameras and specialized voltage meters to pinpoint the heat source without tearing apart your drywall unnecessarily. We can see heat signatures behind walls that your eyes can't detect.
Codes and Regulations
Casselberry and Seminole County have specific building codes designed to keep you safe. Florida Building Code requirements change, and professional contractors stay updated on these changes. For example, recent code updates often require Arc-Fault Circuit Interrupters (AFCIs) in many rooms, which are specifically designed to detect the kind of arcing that causes fires.
Spectrum Electric: Your Local Casselberry Experts
When you call Spectrum Electric, you aren't getting a random subcontractor from a national chain. You’re getting a local team that understands Casselberry’s unique housing mix.
We know the electrical quirks found in the mid-century homes in South Seminole Heights and the specific demands of newer constructions near Red Bug Lake Road. Our technicians are fully licensed, insured, and certified to handle residential and commercial electrical issues.
We pride ourselves on transparency. When we arrive, we inspect, diagnose, and explain the problem in plain English. We’ve helped hundreds of neighbors in this area sleep soundly knowing their wiring is safe. One resident in Deer Run recently told us, "I thought I was going crazy smelling fish in the bedroom. Spectrum found a melting outlet behind the dresser that could have caught the curtains on fire."
Preventative Measures and Maintenance
You don't have to wait for a smell to take care of your home's electrical health. A little prevention goes a long way in our humid climate.
Regular Inspections
We recommend a professional electrical inspection every 3 to 5 years, or immediately if you buy a home over 20 years old. We check the panel, tighten loose connections, and test your grounding system.
Don't Overload Outlets
It’s easy to plug a power strip into a power strip, but that’s a fire hazard. Try to spread high-wattage appliances (like space heaters or air fryers) to different circuits. If you’re constantly tripping breakers, it’s time for a panel upgrade, not another power strip.
Florida Weather Factors
Our humidity is tough on everything, including metal wires. Oxidation (rust) on wires increases resistance. Plus, our frequent lightning storms can send surges through your system that damage insulation over time. Consider installing a whole-home surge protector to guard against Casselberry’s summer storms.
The Cost of Electrical Repairs in Casselberry
One of the first questions homeowners ask is, "How much will this cost?" While every job is different, knowing the ballpark helps you plan.
Typical Repair Costs
For a standard diagnostic call where we investigate a smell or tripping breaker, you’re usually looking at $150 to $300. If the issue is a single melted outlet or switch, replacement and wiring repair typically runs $150 to $250.
However, if the damage has spread inside the wall or requires a new circuit run, costs can range from $500 to $1,200. Panel replacements, if your old panel is the root cause, generally cost between $1,500 and $3,500 depending on the amperage.
Price Factors
The complexity drives the price. Fixing a switch is fast. Rewiring a kitchen circuit because the insulation melted all the way back to the panel takes time and materials. Emergency service calls (nights or weekends) will also carry a premium.
DIY vs. Professional Savings
It seems cheaper to buy a $5 outlet at the hardware store. But if that DIY fix fails and causes a fire, the cost is incalculable. Even a minor mistake that fries your computer or TV costs more than the professional service call would have.
Real-Life Examples in Casselberry
We recently visited a home near Lake Concord Park where the owners complained of a persistent fishy smell in the laundry room. They had replaced the dryer vent, thinking it was a lint issue.
When we used our thermal imaging tool, we found a "hot spot" inside the wall behind the washing machine. It turned out a wire nut had come loose inside a junction box, and the arcing was slowly melting the plastic connector. We cut out the damaged wire, replaced the connector, and verified the circuit was safe. The smell vanished instantly.
Another case involved a home closer to Semoran Boulevard. The homeowner kept smelling fish whenever they ran the microwave. It turned out the microwave was on the same circuit as the living room lights, and the load was too high, cooking the insulation at the breaker panel. We installed a dedicated circuit for the microwave, solving the problem for good.

Frequently Asked Questions
Is the fishy smell toxic?
While the smell itself is mostly just unpleasant, the fumes from burning plastic can be harmful if inhaled in large quantities. More importantly, the smell indicates a fire hazard. Ventilation helps, but stopping the melting is the priority.
Can I just turn off the breaker?
Turning off the breaker is a great first step to stop the heat generation. However, you still need a professional to find where the damage is and repair it before turning the power back on.
How long does a repair take?
Most diagnostic and repair jobs for these odors take between 1 and 3 hours. If we need to run new wires or replace a panel, it could take a full day.
Do you offer emergency services?
Yes, Spectrum Electric offers emergency services because we know electrical fires don't stick to business hours. If you smell burning or see smoke, call 911 first, then call us.
