Out with the Old: Electrical Red Flags in Older Homes

There’s no denying the charm that comes with older homes, the character, the craftsmanship, the history, but these beauties often also house outdated electrical systems that can pose serious risks. At Platinum Power Solutions, owned and operated by Logan Kaisser, we’ve seen firsthand how architectural allure can come hand-in-hand with hidden electrical dangers. Whether you're buying an older home or living in one, it’s critical to recognize the electrical red flags, and know when to call in a pro.

Platinum Power Solutions.

1. Knob-and-Tube Wiring

• What it is: An insulated copper conductor system popular from the late 1800s to about 1940–1950, installed without a ground wire and relying on porcelain knobs and tubes.

• Why it’s risky:

  • Lacks grounding, increasing shock and fire risk.

  • Insulation becomes brittle over time.

  • Cannot handle modern electrical loads.

  
  

• Watch for: Loose wires hanging from ceilings or walls, frayed cloth insulation, missing porcelain supports.

• DIY safety step: If exposed, shut off power and cover until a licensed electrician can assess.

• When to call us: Always. Any knob-and-tube wiring needs professional evaluation and likely replacement.

2. Aluminum Wiring

• What it is: Used between the 1960s–70s as a cheaper alternative to copper wiring.

• Why it’s risky:

  • Oxidizes easily, loosening connections.

  • Expands and contracts more than copper, causing stress at terminals.

  
  

• Signs to know: Flickering, buzzing, blackened or warm outlets; missing ground on three-prong plugs.

• DIY approach: Don’t attempt to fix, any aluminum angle work needs trained professionals.

• Trusted repair: We use standard pigtailing methods with proper connectors or full rewiring to copper.

3. Outdated Fuse Boxes or Panels

• Symptoms:

  • Frequently blown fuses

  • Outlets & breakers that don’t trip during overloads, classic in older panels.

  
  

• Why it matters: Modern homes need more capacity. Old 60A–100A systems can overheat and start fires.

• DIY caution: Label breakers and don’t overload circuits.

• Homeowner alert: Consider a panel upgrade to modern breaker systems, ask us about service capacity and safety enhancements.

4. Missing GFCIs & AFCIs

• What are they?

  • GFCIs (Ground Fault Circuit Interrupters) shut off when detecting imbalance, critical near water.

  • AFCIs (Arc Fault Circuit Interrupters) prevent fires from arcing faults.

  
  

• The warning signs: Older homes often built before these devices existed, no bathroom or kitchen GFCIs, living room circuits lack AFCI protection.

• Is this DIYable?: Replace an outlet? OK, but proper installation and labeling is safest with help.

• Our work: We can retrofit GFCIs and AFCIs to meet Manitoba and Canadian Electrical Code.

5. Overloaded Circuits & Extension Cord Dependence

• What to watch:

  • Power strips, heaters, space heaters, small appliances on one circuit, all overload circuits.

  
  

• Signs to look for: Lights flickering, outlets or switches heating up, frequent breaker trips.

• DIY solution: Spread devices out or run extension cords temporarily.

• When to call: If you rely on extension cords daily, it’s time for additional outlets or upgraded circuits.

6. Frayed Wires, Open Junction Boxes & DIY Modifications

• What they are:

  • Exposed junction boxes, backstabbed outlets, homemade pigtails behind switches.

  
  

• Why they’re risky: Loose wiring can arc and cause fires.

• Moderate fix: Tighten screws or add covers, but only if comfortable and safe to isolate the circuit.

• Time to call: Any improper wiring needs a licensed electrician to fix and re-box correctly.

7. Buzzing, Warm or Discolored Outlets & Switches

• What to watch for:

  • Dimming lights, buzzing sounds, heat or a burning smell from switches or outlets.

  • Dark marks, flicker, loose sockets, dangerous ahead of fire risk.

  
  

• What to do: Shut off the circuit and leave it off.

• Our service: Available 24/7 to troubleshoot and replace defective components.

8. Lack of Proper Grounding

• Why it matters:

  • Uncovered outlets or appliances may lack a real grounding path, risking shock and damaging electronics.

  
  

• You can test: Use an outlet tester or plug in a grounded device.

• Pro tip: Only electricians should rewire grounding or install subpanels, leave it to us.

9. Old Appliances & Overlamping

• What it is:

  • Electric blankets, untested kettles, or lamps pulling more wattage than safe .

  
  

• DIY tip: Replace dimmers and bulbs with correct wattage; upgrade unsafe appliances.

• Professional help: We can add dedicated circuits for high-draw items (ACs, EV chargers, hot tubs).
