Flickering Lights in Home

Loose wiring is the most serious reason for flickering lights and a main cause of house fires. Shut off the light at the circuit breaker before removing the fixture to double check the wiring. If the fixture looks like it might be loose or insecure, it’s time to call an electrician.

What Causes Flickering?

Flickering light bulbs are a common problem.
Flickering is a simple drop in voltage that causes your lights to dim. A variety of around-the-house issues can cause your lights to flicker.

How you can fix flickering bulbs around your home?

Bulb type.

Glowing/Flaming lights are more susceptible to flickering than LED and other bulb types. Temperature, bulb age, and warm-up cycles are common causes of fluorescent flickering. Small amounts of flickering aren’t a cause for concern. Replace your flaming bulb to address severe flickering or dimming.

Dimmer switches.

Dimmer switches are a common source of flickering with LED bulbs. Most dimmers are manufactured for higher electrical loads. As a result, low-voltage LEDs can flicker and dim on high-powered dimmer switches. It’s a good idea to check the bulb compatibility of your dimmer before purchasing new bulbs.

Loose bulbs.

Unseated bulbs rattle in their sockets, resulting in inconsistent wiring connections and regular flickering. Tightening the bulb will ensure a solid connection and eliminate any dips in the current.

Faulty connections.

A bad connection in your lamp or fixture’s on-off switch can result in flickering. Troubleshoot the connections by wiggling the on-off switch. If your lights dim, you have a bad switch. Replacing switches can be difficult. Call a professional if you’re unsure how to tackle this project. Plugs can also cause bad connections. Pull the plug out and straighten the prongs. Sometimes, bent or damaged prongs can create a bad connection.

Large current draws.

Larger appliances can pull 100 or more amps when cycling on. This surge in power can cause your lights to dim and flicker. Call an electrician to ensure your appliances are wired correctly and aren’t overworking your home’s circuit.

Problematic Flickering

Flickering lights are normally not cause for alarm. But sometimes they can indicate a more serious problem. Constant or severe drops in lighting can result from loose connections. Faulty wiring connections create points of high resistance, which can generate unsafe levels of heat. Old breakers can also cause flickering. Similar to your home’s electrical systems, the wiring in your breakers can go bad over time. Faulty breaker wiring can short and overheat, which can cause flickering. Always call a pro to address these problems.

Installing a New Fixture

Old or damaged fixtures can cause a variety of problems, including flickering. Here’s how to install a new fixture in your home:

    Step 1. Turn off the power. Locate your breaker box and turn off the breaker that controls the power to the room where you’ll be working. Turn off your power main if you’re unsure which breaker controls your room.

    Step 2. Remove the fixture. Remove the fixture cover to reveal the set screws. Loosen the set screws to remove the fixture’s trim. After the trim is gone, disconnect and untwist the wires from the old fixture. This should expose the electrical box.

    Step 3. Check the electrical box screws. Ensure the screws holding your electrical box in place are tight enough to support your new fixture.

    Step 4. Connect the wires. Always match the black (hot), white (neutral) and ground wires together. Ground wires are usually bare copper or green. Some fixtures contain a grounding screw instead of a wire. If your electrical box has a ground wire, connect it to the screw. Most grounding screws are green.

    Step 5. Secure the base. Fold the wires into the electrical box and push the fixture toward the ceiling. Attach the fixture to the ceiling.

    Step 6. Install the light bulbs. Screw in the light bulbs and install the globe or glass cover.

    Step 7. Power on. Flip the breaker to restore power to your work-space.

Installing basic light fixtures is a simple job. But updating large or ornate models isn’t always a DIY-able job. Call a pro if you’re unsure about tackling this project yourself.

Overall excellent service, from beginning to end, we called STS Electric and got the information we needed in terms of the scope of the job, pricing and time it will take to complete it. It was within our budget and time frame so we decided to hire them for the job. They were super efficient, no headache, came in, scoped everything and start the work, they were done in a few hours and everything worked out perfect. Thanks.
I highly recommend STS Electric. The guys were great. They explained everything to us & did the job in a timely fashion.
⁠The team came to install my ev charger. They were fast and very kind. Would definitely call them again.
If you live in the Chicago area, I strongly suggest you look no further for your electric needs but to go with the best company I have ever worked with. From the office staff, supervisors and technicians are rated 10 out of 5 if that was possible. An amazing service rendered and as a very satisfied customer they will stay with me for all future projects.The detailed and precision of this service was unbelievable. Knowledgeable, courteous and detailed customer care was a plus for me. I had no worries when worked began because I felt I was in safe hands. The results were flawless. I am a very satisfied customer and recommend to all.
STS Electric arrived on time and quickly resolved our electrical problems, and replaced 2 Ring camera/lights devices. I will continue to use him when I need help with electrical issues.
Being first time EV owners, we had quite a bit to learn about the process of getting an EV charger installed in our home garage. Ana was very responsive and arranged for a same day in person consult. Our project manager, Sam, was both friendly and extremely knowledgeable, we appreciated that he took his time with us as we had many questions. After we decided to proceed, they scheduled us within the same week. Our electrician Francisco did great work and finished the project in one day. He even performed the drywall himself. Highly recommend this company!
Sam and the team were great and promptly completed the outlet installation and integration
My STS electrician experience was fantastic, I had them come in to do a few different projects and they were great. I love how the communication (for me, from Ana) is clear, kind, and concentrated on my needs; I love how the guys who came (for me, Francisco and Juan) were talented, kind, listened to my concerns, and just plain got the job done! I'm getting these guys back to do more work, but for now I'll say: You're in good hands.

STS Electric has been a life savior for me! Their electricians are attentive, friendly, and dedicated, always going above and beyond to address the customers needs. I called on a Monday, and was able to get 2 - 3 electricians on the job on Tuesday, the very next day and scheduled throughout the week.

They've done all my rewiring for me, and they do the job in a timely manner. When they work, they put plastic everywhere to make sure my belongings stay clean and not so dusty.

The supervising electrician, Sam, has been absolutely wonderful. He explains everything step by step to me in laymans terms that I can easily understand. Ana who schedules and deals with the finances is super nice and dedicated as well! And the electricians Francisco and José were also very communicative about what work they were going to do and ensured that all my outlets, switches, and new fixtures were located exactly where I wanted them to be with electrical code compliance in mind.

STS Electric is the type of business I know I can rely on in a pinch. Just a really great team with high quality workmanship. I highly recommend this company!
