If your lights flicker every now and then, you might not think much of it.

But here’s the truth…

Sometimes it’s minor
Sometimes it’s a warning sign of something bigger

We see this all the time in homes across Thornton, Northglenn, Westminster, Brighton, Commerce City, and Broomfield — especially in older homes or homes with upgraded appliances.

Let’s break down what’s really going on.

What Causes Lights to Flicker?

There’s always a reason — lights don’t flicker randomly.

Here are the most common causes we run into:

1. Loose Bulb or Fixture (Simple Fix)

Sometimes it’s as simple as:

• A loose bulb
• A worn-out fixture

Always check this first.

2. Circuit Overload

If lights flicker when something turns on (microwave, AC, etc.)…

That usually means your circuit is overloaded.

3. Voltage Fluctuations

This is more serious.

If lights dim or flicker when larger appliances start:

• HVAC system
• Washer/dryer
• Refrigerator

Your system may be struggling to distribute power properly.

4. Loose Wiring (DANGEROUS)

This is where things can get risky.

Loose wiring can cause:

• Intermittent flickering
• Heat buildup
• Fire hazards

This needs to be checked immediately.

5. Electrical Panel Issues

If your panel is outdated or overloaded:

It can’t supply consistent power throughout your home.

This ties back to a lot of what we see in older homes in this area.

When Flickering Lights Are a Warning Sign

Call an electrician if:

• Flickering happens in multiple rooms
• Lights dim when appliances turn on
• You notice burning smells
• It’s getting worse over time

These are not “wait and see” issues.

Why This Happens in Homes Around Here

Homes in Thornton, Westminster, and Northglenn were built with different electrical demands in mind.

Back then:

• Fewer appliances
• Smaller panels
• Less load

Now?

Everything pulls power — and older systems struggle to keep up.
