Have you ever noticed your lights flickering when you turn on the microwave? Or maybe you felt a warm spot on a wall near a plug?

When the wires in our homes get old or weak, it can become a real danger. That is why many families choose Firefly Electric Service to keep their lights on and their families safe. Why take a chance with old wires when help is just a phone call away?
Why Home Wiring Matters for Your Safety
We often forget about the wires in our house because we cannot see them. They hide behind the drywall and run through the attic. But just like a car or a roof, your electrical system wears down over time. In older houses, the wires might not be strong enough for today’s big TVs and fast computers.
If your wiring is too old, it can get hot and start a fire. According to the National Fire Protection Association, electrical failures or malfunctions cause more than 40,000 home fires each year. That is a very big number. We want to help you make sure your home is not part of that group. Have you thought about how much more power we use now compared to thirty years ago? We use more gadgets than ever, and our wires need to keep up.
The Signs of Bad Wiring in Your House
We want you to know what to look for so you can stay safe. Your house usually tries to tell you when something is wrong.
- Flickering Lights: This often means a wire is loose somewhere.
- Tripping Breakers: If your power goes out often, your system is overloaded.
- Burning Smells: This is a big emergency. It means a wire is melting.
- Popping Sounds: If you hear a click or a pop when you plug something in, that is a spark.
We suggest checking your outlets every few months. If they look charred or black, stop using them. We want to help you fix these small problems before they turn into big ones. Is it worth waiting for a total power failure to call a pro?

How the Rewiring Process Works
We know that the idea of “rewiring” sounds like a big mess. You might think we have to tear down every wall. But we use special tools to fish wires through the walls with very little damage.
First, we check your electrical panel. This is the heart of your system. If the panel is too small, we update it. Then, we run new copper wires to every room. We also install GFCI outlets in kitchens and bathrooms. These outlets turn off the power instantly if they get wet. This stops people from getting a bad shock. We take our time to make sure every connection is tight. We want you to feel good every time you flip a switch.

The Advantages of a Contemporary Electrical Board
Your electrical panel is similar to your home’s brain. It informs electricity about its destination. If your panel is older, it might have fuses versus breakers. Fuses are not as safe as breakers as they don’t trip when they’re supposed to.
When we update your panel, we give you more “amps.” Amps are like the width of a pipe. A wider pipe allows more water to flow. A larger panel allows for more power to flow. This means you can have your air conditioning, dishwasher, and hair dryer all running at once with no problems at all. We want to make your daily life easier and safer.
Keep electronics safe
We all invest significant amounts of money on our gadgets and mobile phones. A power surge can damage these devices in one second. An unexpected spike in electricity is a power surge. A storm, or the starting of a large machine close by, can set this off.
A whole-house surge protector can be installed at your main panel. Your whole home is covered with this like an umbrella. It prevents the large surges from getting to your outlets. Your fridge, your television and even your chargers are protected. It may seem like a tiny addition, but it saves you a lot of money later on. Have you ever had a computer killed by lightning? We can assist in preventing a recurrence of that.
DIY is not a Solution to Your Problem.
We see videos on the internet that help you fix things yourself. However, electrical work is not like painting walls or fixing shelves. If you err, you can hurt yourself or start a fire that is nonetheless not visible for weeks afterwards.
Professional electricians attend school for years to learn the rules. We have devices that can inform us if a wire is energized, or if a ground is missing. We understand how to obtain the correct permits from the city as well. It’s vital for your insurance. If you experience a fire due to unprofessional wiring, your insurance may refuse to pay for any associated damage. Our aim is to spare you of such troubles.

No, generally you will not have to move out. We work during daytime hours and attempt to keep the noise and dust to one area at a time. We ensure you have power to run your fridge and essential light during night. It is easy for most families to remain indoors while we work on the wires.
What’s the best way to check my outlets?
A grounded plug fits an outlet with three holes. The third hole is for the ground wire, which directs any extra electricity away in case of a fault. Nonetheless, sometimes a three-hole outlet is installed without connecting the ground wire. We can check your outlets with a special tester to see if they are really safe and grounded.
