Key Takeaway
A Toronto homeowner hired a plumber for an $8K bathroom reno. Two months later, the bill hit $40K. Here's the story — and how to make sure it never happens to you.
I want to tell you about Sarah.
She's not a name you'll recognize. That's intentional. But her story? You might recognize that.
She's in her early 40s. Owns a semi-detached in East York. Two kids, a husband, a dog named Biscuit. Normal life. Solid home. One bathroom that had been slowly falling apart for three years — chipped tiles, a leaky faucet that dripped every night, a vanity from 2004 that she'd repainted twice to avoid dealing with it.
She finally decided: enough. Time to fix the bathroom.
What followed was six months she'll never forget. And not in a good way.
It Started With a Google Search
Sarah did what every homeowner does. She searched "hiring a plumber Toronto" and scrolled through the results. She found a guy — let's call him Mike — with a small business, a clean website, and 4.6 stars on Google. Twenty-three reviews. Most of them glowing.
"Fast, reliable, great price.""Did an amazing job on our basement bathroom.""Would definitely recommend."
She called him. He showed up on time. He was friendly. He walked around the bathroom, nodded at the right moments, and gave her a number: $7,800 for a full bathroom gut and renovate. New tile, new fixtures, updated plumbing.
Sarah thought: that sounds reasonable.
That thought cost her $32,000.
The First Red Flag She Missed
Mike didn't bring a contract.
Sarah asked about paperwork and he waved it off. "Don't worry, I'll send something over." He never did. She followed up once. He said he was busy, would get to it. She let it go.
This is the part where I wish I could go back and shake her. Not because she was naive — but because she was normal. Most homeowners don't know that a vague verbal agreement is basically no agreement at all.
No written scope. No line-item breakdown. No payment schedule. Nothing.

Work started two weeks later. Mike and one helper. The old tiles came down. The vanity came out. The bathroom was gutted in two days.
And for a while, it looked great.
The Price Starts Climbing
Week two, Mike called Sarah at 6:30 PM.
"Hey, so we opened up the wall and there's some old galvanized pipe in here. It's gotta come out. That's going to be extra."
How much extra?
"Probably around $1,200."
She said okay. What else could she say? The wall was already open.
Week three, another call. The subfloor had some rot. Another $800. Then the shower pan needed to be rebuilt from scratch — not the cheap kind — because the original framing wasn't level. Another $1,600.
Every week, a new "discovery." Every week, a new invoice.
Sarah started keeping a running total in her phone's notes app. It was already past $11,000. Mike kept saying they were almost done.
They were not almost done.
The Moment Everything Changed
It was a Tuesday morning in November.
Sarah's husband was in the kitchen making coffee when he noticed a soft spot in the ceiling below the bathroom. He pressed it. The drywall gave slightly. He looked at Sarah. She looked at him.
They called Mike.
Mike came over, looked at it, and said what no homeowner ever wants to hear:
"Yeah. That's water damage. Looks like it's been leaking for a bit."
A bit. The understatement of the year.
The pipe behind the wall hadn't been installed correctly. Water had been slowly seeping into the subfloor and ceiling below for weeks. Not a flood. A slow, invisible drip. The kind that doesn't make noise. The kind that destroys everything quietly.
Sarah stood in her kitchen staring at her ceiling and felt something she described to me as "a cold door closing in my chest."
The Part That Breaks You
This is where the renovation gone wrong stops being a renovation story and becomes something harder to talk about.
They called a water damage remediation company. The guy showed up with moisture meters and probed every wall in the bathroom and the room below. He handed them a report with numbers that didn't make sense.
Mold. Behind two walls. In the subfloor. Starting in the ceiling of the room below.
Full remediation quote: $18,500.
Sarah sat in her car in the driveway and cried for twenty minutes.
Her husband wanted to call a lawyer. They fought about it that night. They fought about who had approved the work, who had trusted Mike, who had been too busy to read the warning signs. It wasn't a clean fight. It was the kind that has too much in it — stress and money and fear and exhaustion all coming out sideways.
The bathroom wasn't done. The remediation hadn't started. And they were already past $29,000.
Sarah told me she stopped sleeping around that time. Not fully — she'd drift off and then snap awake at 2 AM running numbers in her head, trying to figure out what they could cut. She started skipping lunches to save money. Her husband started working weekends.
The dog, Biscuit, seemed confused by all the tension. He'd try to sit in Sarah's lap while she did the math again, like maybe that would help.
It didn't help.
The Full Picture
By the time it was over, the total cost was $43,200.
That included:
Mike's final invoice: $14,400 (from an original $7,800 quote)
Water damage remediation: $18,500
New contractor to finish the bathroom correctly: $8,200
Two hotel nights during remediation: $340
A lawyer's letter to Mike that ultimately went nowhere: $750
Mike's response to the lawyer's letter was to say the water damage was pre-existing. He had no documentation to prove that. Neither did Sarah — because there was no contract, no scope, no before-photos, no inspection sign-off. Nothing.
Without a paper trail, you have no case. That's just the truth.
What Sarah Learned — And What I Want You to Understand
Here's the thing. And I need you to really hear this.
Mike wasn't some cartoon villain. He wasn't deliberately running a scam. He was a guy who probably did okay work on simpler jobs, had some decent reviews, and was in over his head on this one.
That's almost worse.
The problem wasn't that Sarah hired a "bad" plumber. The problem was that there was no system in place to protect her when things went sideways.
No license verification. No insurance check. No written contract. No permit pulled for the plumbing work. No inspection at key stages. No accountability.
When any of those systems fail — or worse, when none of them exist — you're just hoping. And hope is not a renovation plan.
Sarah told me she's not angry at Mike anymore. She's angry at herself, a little, for not knowing what she didn't know. For trusting a Google review when she should have trusted a process.
"I didn't know what questions to ask," she said. "I didn't know there were questions."
How to Protect Yourself: The Non-Negotiables
I'm not going to give you ten steps and a checklist. Here's what actually matters when hiring a plumber in Toronto or anywhere in Canada:
1. Verify the license. Every time.
In Ontario, plumbers must be licensed through the Ontario College of Trades. You can check online. Takes two minutes. Do it every single time, no exceptions.
2. Demand a written contract before a single nail is touched.
This document should include: full scope of work, payment schedule, what happens if unexpected issues arise, timeline, and warranty terms. If they push back on this, that IS your answer.
3. Check insurance — and ask for proof.
They should carry general liability insurance and WSIB coverage. Ask for a certificate. A legitimate contractor will have it ready.
4. Get at least three quotes.
Not to find the cheapest — to understand the range and what's actually being offered. A quote that's dramatically lower usually means something is being left out.
5. Ask how permits and inspections are handled.
In Toronto, most significant plumbing work requires permits. If your contractor says you don't need one — ask why. Then verify independently.
6. Never pay more than 10-15% upfront.
A common contractor scam is a large deposit that disappears with the contractor. Progress payments tied to milestones protect you.
7. Take photos before, during, and after every stage.
If anything goes wrong, documentation is everything. Before the walls close up, photograph every pipe, every connection, every material used.

When you hire through GetAHomePro, you're not hoping. You're choosing from a pool of tradespeople who have already been checked.
Sarah rebuilt her bathroom. She loves it now. But she told me something that stuck with me: "I wish I'd had a place that did the homework for me. I didn't know I needed it until I really, really needed it."
You don't have to learn this lesson the hard way.

FAQ
How do I verify a plumber's license in Ontario?
You can check through the Ontario College of Trades website at collegeoftrades.ca. Enter the contractor's name or registration number to confirm their license status. It takes two minutes and could save you tens of thousands.
Is a written contract legally required for home renovations in Ontario?
For contracts over $50, Ontario's Consumer Protection Act requires a written agreement for specific types of home services. But even where it's technically optional, you should always demand one. A verbal agreement is nearly impossible to enforce.
What should I do if I discover water damage during a renovation?
Stop work immediately. Document everything with photos and video. Get an independent moisture assessment before any remediation begins. Contact your home insurance provider — water damage from contractor error may be partially covered depending on your policy.
How do I know if my contractor pulled the right permits?
You can check with your local municipality. In Toronto, visit the City of Toronto's building permit status portal and search by address. Unpermitted work can cause serious problems when you sell your home or make an insurance claim.
