Monroe County has a lot of older housing stock — homes built in the 1940s, 50s, and 60s that were wired for a completely different era of electrical use. Many of these homes carry risk that homeowners don't know about until something goes wrong. Here are the signs to watch for.
8 Warning Signs to Watch For
Flickering or Dimming Lights
Occasional flicker when appliances kick on can be normal. Persistent flickering — especially throughout multiple rooms — often signals a wiring issue in the circuit or at the panel connections.
Burning Smell
A burning smell from an outlet, switch, or your electrical panel is a serious warning sign. This indicates wiring is overheating. Turn off the circuit and call an electrician immediately.
Discolored Outlets or Switch Plates
Yellowing, browning, or charred outlet covers mean the outlet has overheated. This is a fire precursor. Stop using the outlet and call for service.
Buzzing or Crackling Sounds
Electrical wiring should be silent. Buzzing from outlets, switches, or the panel indicates loose connections or arcing — a direct fire risk.
Two-Prong Outlets Throughout
Two-prong (ungrounded) outlets throughout the home indicate pre-1960s wiring that lacks the ground conductors required by modern code. This also means your home likely has other outdated wiring.
Knob and Tube Wiring
Common in Monroe County homes built before 1950. Knob and tube isn't necessarily dangerous if it's intact and not covered with insulation, but it can't be extended, has no ground conductor, and most insurance companies won't cover homes with it.
Aluminum Wiring at Connections
Homes built from 1965–1975 sometimes have aluminum wiring, which expands and contracts differently than copper. Connection points can loosen and arc. This requires a specific fix — not just replacing outlets.
Frequently Tripping Breakers on Normal Loads
If your breakers trip regularly under normal household use, your wiring may be undersized for your current electrical load — a sign the system needs upgrading.
Does Your Whole House Need Rewiring?
Not necessarily. A full rewire is needed when wiring is dangerously degraded throughout the home, or when a complete update is more economical than patching multiple problem areas. Often, targeted work — replacing a few circuits, updating connection points on aluminum wiring, or upgrading the panel — addresses the risk without a full rewire.
Premier Alarms and Electric assesses what's actually needed — no overselling, no recommending a $15,000 rewire when $2,000 of targeted work solves the problem. You'll get an honest assessment and a clear recommendation before any commitment.

How do I know if my home has knob and tube wiring?
Knob and tube wiring is visible in unfinished attics and basements as ceramic knobs and tubes running along joists with cloth-covered wires. It was common in homes built before 1950. A licensed electrician can confirm whether your Rochester home has it during an inspection.
Is aluminum wiring dangerous in Rochester, NY homes?
Aluminum wiring used in homes built from the late 1960s to mid-1970s can be a fire hazard at connection points. It's not always an emergency, but it does require specific attention — either replacement of connection points with CO/ALR-rated devices or full replacement. Have a licensed electrician assess it.
How much does rewiring a house cost in Rochester, NY?
Full rewiring costs vary widely by home size and complexity. A typical 1,500–2,500 sq ft Rochester home runs $8,000–$20,000 depending on accessibility. Partial rewiring (updating specific circuits) is significantly less. Call Premier Alarms and Electric at (585) 371-8893 for a free assessment.
Will homeowners insurance cover my Rochester home with old wiring?
Many insurance companies in Monroe County surcharge or deny coverage for homes with knob and tube wiring, Federal Pacific panels, or aluminum wiring. Updating these systems often reduces premiums enough to partially offset the cost.
