Buying or selling a home: the electrical inspection

Residential · Commercial · Industrial — Montréal, Laval & North Shore

Electrical issues are among the most frequent deal-breakers in a real-estate transaction. Here’s what the inspection reveals, what a buyer or insurer can demand, and how to prepare.

The context

Electrical issues carry weight

Whether you’re buying or selling, the state of the electrical installation can lower a price, delay a transaction or complicate insurance. A check by our team puts the cards on the table — before things stall.

In the field

The top defects we find

Aluminum wiring

By far the most important component to evaluate. It changes everything in a negotiation (see below).

Panels that need replacing

Some brands should simply be changed for safety reasons (list just below).

Service entrances

Frequently at issue: an aging entrance, rusty mast, or capacity too low for the house.

Small fixes

Missing GFCI outlets, unsafe installations… Often small things that are fixed fairly easily.

Red flags

The panels we recommend replacing

As soon as we see one of these panels, we strongly recommend changing it:

  • Federal Pioneer / Stab-Lok
  • Commander
  • Fuse panels
  • Old GE panels
To understand why, see our article on aluminum wiring and our coverage of dangerous panels.
The heaviest bargaining chip

Aluminum wiring

Aluminum wiring is a very, very important component. It doesn’t “kill” a sale by itself — but it’s a considerable negotiating argument. Because if the buyer wants to rewire everything, it’s a major undertaking.

≈ $40,000

A real case: a house entirely wired in aluminum. The buyer wasn’t comfortable with that type of wiring and wanted to rewire it all — a bill of about $40,000. He was very glad to have paid for our inspection to know that before signing, and to adjust his offer accordingly.

In practice

About 2 hours, checking everything that matters

An inspection takes about two hours. We genuinely check everything that could pose a risk to occupant safety and building integrity — from the panel to the service entrance, through the wiring and protections.

Not to be confused

Pre-purchase inspection ≠ certificate of conformity

Pre-purchase inspection

An inspection with a quote attached, so you can negotiate your purchase price with full knowledge.

Certificate of conformity

A document required by an insurer. Not the same thing, and not the same purpose.

Federal Pioneer / Stab-Lok, Commander, fuse panels and old GE panels. We generally recommend replacing them.
