The call came on a Tuesday. A woman in Nassau had paid a contractor $14,000 to renovate her kitchen. New wiring, new fixtures, new everything. Three weeks in, her outlets started buzzing. Then the breaker tripped every time she used the microwave. The contractor had vanished — phone disconnected, no forwarding address.
She called me to fix the paint after another crew rewired the kitchen. What I saw when I walked in made my stomach turn. Live wires buried behind drywall. Junction boxes hidden in the ceiling with no access panel. A ground wire twisted around a drywall screw and called "good enough."
I've been painting and renovating in the Bahamas since 1992. I've walked into the aftermath of bad electrical work more times than I can count. And here's the thing most homeowners don't realize: the electrical problems you can't see are the ones that burn your house down.
Here's what nobody in the trade will tell you about electrical safety during a renovation.
Contractors know that homeowners don't check their work. They know you won't open a junction box. They know you won't test an outlet beyond plugging in your phone charger. They count on it. The bad ones, anyway — and there are enough of them to make the whole trade look dirty.
The good ones? We want you to check. We want you to ask questions. A homeowner who knows what to look for is a homeowner who won't get taken.
So here are four things every homeowner should do before, during, and after a renovation — things that take minutes but save thousands.
1. Test every outlet before you pay the final invoice.
Not with your phone charger. With a real voltage tester. Plug something into every single outlet. Flip every switch. If an outlet is dead, if a switch controls nothing, if a GFCI won't reset — that's not "a minor thing." That's incomplete work, and you don't pay for incomplete work.
This is exactly why I tell every homeowner I know to keep a non-contact voltage tester in their kitchen drawer. The Klein Tools NCVT-1 costs about $27. You hold it near an outlet or a wire and it lights up and beeps if there's voltage present. No contact, no risk, no skill required. If your contractor says an outlet is live and the tester says it's dead — you just caught something before it became a problem.
2. Ask to see the junction boxes before drywall goes up.
This is the moment. Once drywall is hung, you will never see that wiring again for 30 years. Ask your contractor: "Can I see the junction boxes before you close the walls?" A good contractor says "of course." A bad one gets uncomfortable. Watch their face when you ask — that reaction tells you more than any reference check.
What you're looking for: boxes that are accessible (not buried), wires that are capped and organized, no exposed copper. You don't need to be an electrician to spot a mess.
3. Map your breaker panel before the project starts — and after it ends.
Take a photo of your breaker panel on day one. Label every circuit yourself — don't trust the contractor's labels. After the renovation, do it again. If new circuits were added and they're not labeled, that's a red flag. If breakers trip constantly after the job is done, that's not "just how it is" — that's a problem they left behind.
4. The one question that exposes a bad contractor instantly.
Ask this: "Who's doing the electrical work — you or a licensed electrician?"
In most jurisdictions, electrical work requires a licensed electrician. A general contractor who says "I do it all myself" without an electrical license is either cutting corners or breaking the law. Either way, you don't want them in your walls.
What the uninformed homeowner does: Signs the contract, writes the check, and trusts that everything behind the walls is done right because the contractor seemed nice at the estimate.
What you'll do now: Walk through with a $27 voltage tester, ask to see the junction boxes before drywall, map your breakers, and ask who's doing the electrical work. Four steps. Maybe 30 minutes total. The difference between a home that's safe for 30 years and one that's a fire hazard.
I've spent 34 years fixing what other tradesmen left behind. The electrical problems are always the scariest because you can't see them until something goes wrong — a fire, a shock, a fried appliance. A non-contact voltage tester like the Klein NCVT-1 won't make you an electrician. But it will tell you in 30 seconds whether an outlet is live or dead, whether a wire is hot when it shouldn't be, whether your contractor did what they said they did.
For bigger checks — verifying voltage, testing continuity, diagnosing why that new circuit keeps tripping — I use the Klein MM400 multimeter. It's the next step up. But start with the voltage tester. It's the tool that gives you the confidence to ask the right questions.
You didn't hire a contractor to gamble with your family's safety. Stop gambling. Start checking.
