What electrical safety checks should I do before buying an older home in New Brunswick?

Before buying an older NB home, hire a licensed electrician for a dedicated electrical inspection beyond the standard home inspection — it costs $200-$400 and can save you thousands in unexpected repairs.

Why the standard home inspection isn't enough:

A general home inspector checks visible electrical components but typically doesn't open panels, test individual circuits, or evaluate wiring behind walls. In New Brunswick's older housing stock — particularly pre-1980 homes common across Moncton, Fredericton, and Saint John — hidden electrical issues are among the most expensive surprises for new homeowners.

Critical checks for NB homes by era:

Pre-1950 homes (common in Saint John, Fredericton downtown):

• Knob and tube wiring: Still energized in many older NB homes. Not inherently dangerous if untouched, but cannot contact insulation and may need full replacement. Cost to rewire: $15,000-$30,000


• 60-amp fuse panel: Severely undersized for modern use. Panel upgrade: $2,500-$4,500


• Cloth-wrapped wiring: Insulation deteriorates, exposing conductors. Urgent replacement needed if crumbling

1965-1976 homes:

• Aluminum wiring: Very common in NB homes from this era. Check every connection point for signs of overheating (discoloured outlets, melted plastic). Pigtailing remediation: $2,500-$5,000


• 100-amp panels: May be adequate but check available capacity — electric baseboard heat often maxes these panels

1970s-1990 homes:

• Federal Pacific Stab-Lok panels: Known fire hazard — breakers fail to trip during overcurrent. If present, budget $3,000-$5,000 for replacement. This is non-negotiable


• Zinsco/Sylvania panels: Similar concerns to Federal Pacific


• Backstab wiring connections: Quick-connect terminals on outlets loosen over decades, causing arcing

All older homes — check for:

• Panel capacity: Is it 100A or 200A? What's the available capacity after existing loads?


• Grounding: Are outlets properly grounded? Two-prong outlets throughout means ungrounded wiring


• GFCI protection: Required in bathrooms, kitchens, outdoors, garages. Often missing in pre-2000 homes


• AFCI protection: Required on bedroom circuits. Missing in pre-2015 installations


• Permit history: Check with TSANB if electrical work was done — unpermitted work is a red flag


• Visible hazards: Open junction boxes, exposed wires in basement or attic, double-tapped breakers, oversized fuses

How to use findings in negotiations:

• Get the electrician's report in writing with estimated repair costs


• Request a price reduction or have the seller complete repairs before closing


• Major electrical issues (full rewire, panel replacement) can justify $10,000-$30,000 in price negotiation


• Some NB mortgage lenders require panel replacements (especially Federal Pacific) before funding

Insurance implications:

• Many NB insurers won't cover homes with knob and tube, aluminum wiring, or Federal Pacific panels without remediation


• Get insurance quotes BEFORE making an offer — you may discover the home is uninsurable without significant electrical upgrades


• Ask the insurer specifically about known panel brands and wiring types

Your action plan: Make your purchase offer conditional on a satisfactory electrical inspection by a licensed electrician. This costs you $200-$400 and provides ammunition for negotiation or a clear exit if the issues are too severe.
