Older homes in Marysville have charm.
They also hide serious electrical risks.
If your home was built decades ago, you may face electrical problems in older homes that modern systems no longer support.
These issues affect safety, comfort, and resale value.
This guide shows what goes wrong, why it happens, and how you fix it the right way.

Your home now runs more devices than ever.

These older home electrical problems often stay hidden until failure occurs.

- Balance electrical loads
- Upgrade panel capacity
DIY fixes make this worse.
A licensed electrician solves it safely.
Flickering or Dimming Lights
Flickering lights are not normal.
Possible causes include:
- Loose wiring
- Failing switches
- Panel overload
- Aging fixtures
These electrical problems in older homes can signal fire risk.
A professional inspection finds the cause fast.
Faulty Outlets and Switches
Worn outlets fail quietly.
Watch for:
- Loose plugs
- Sparking
- Cracked plates
- Hot switches
These electrical issues in older houses often hide behind walls.
Replacing outlets restores safety and reliability.
Ungrounded or Two-Prong Outlets
Two-prong outlets lack grounding.
They increase shock risk.
Modern homes require grounding for:
- Appliances
- Electronics
- Surge protection
How to fix older home electrical problems here:
You install grounded outlets and GFCI protection.

Lack of Modern Safety Devices (GFCI / AFCI)
Older homes rarely include these devices.
Why GFCI and AFCI Matter
- GFCI protects from shock
- AFCI prevents electrical fires
- Both are code-required today
Without them, your home stays vulnerable.
Our team upgrades these systems quickly and cleanly.
