Top Questions to Ask Before Hiring a Plumber in Toronto

Plumbing problems are stressful and can cause a lot of damage if not fixed timely. A leaking pipe, a clogged drain, or a broken water heater can cause big trouble. But fixing plumbing issues is not just about fixing it fast. It’s about fixing it the right way. That is why you need to hire a professional and reliable plumber.

If you live in Toronto, there are many plumbers to choose from. Some are skilled and honest. Others are not. Knowing the right questions to ask a plumber before you hire will help you find the right one. 

Here is a quick checklist before you hire a plumber in Toronto:

• Confirm licensed and insured plumbers status.
• Check proof of insurance and bonding.
• Learn about plumber’s experience and years in business.
• Ask about specialized plumbing services if needed.
• Read plumbing company reviews and speak to past customers.
• Get a detailed plumbing estimate with transparent pricing / no hidden fees.
• Ask about the plumbing warranty and what it covers.
• Confirm emergency plumbing service details.
• Ask who will do the work and if clean-up after the job is included.
• Make sure they know Toronto plumbing codes and permits.
• Compare quotes carefully.

Why Ask Questions Before Hiring a Plumber in Toronto?

When a pipe bursts or your toilet overflows, it’s easy to panic. Many people call the first plumber they find online. But rushing can be a mistake. If you choose the wrong plumber, you may end up with poor work, hidden costs, or even damage to your home.

Asking questions helps you:

• Find a licensed plumber who meets Ontario standards.
• Avoid surprise bills with transparent pricing and no hidden fees.
• Choose someone with the right plumber’s experience for your problem.
• Make sure your plumber will offer a fair plumbing warranty.
• Check plumbing company reviews before you decide.

The best plumbers are happy to answer your questions. They show respect, explain clearly, and make you feel at ease.

Top 9 Questions to Ask a Plumber in Toronto Before Hiring

1. Are You Licensed and Insured?

Your first question should always be about licensing. In Ontario, all plumbers must be certified by the Ontario College of Trades (now under Skilled Trades Ontario). This certification ensures they have completed the necessary training and testing to meet provincial standards.

Ask for the plumber’s licence number and verify it through the Skilled Trades Ontario public registry. A legitimate plumber will be happy to provide it. If someone hesitates or refuses, that’s a red flag, move on to the next candidate.

Equally important is insurance. A reputable plumber should carry both liability insurance and Workplace Safety and Insurance Board (WSIB) coverage. This protects you from being held responsible for injuries or damages that occur during the job. Before work starts, ask to see proof of current insurance.

2. How Many Years Have You Been in Business? What Do You Specialize In?

Plumber’s experience matters. A plumber who has worked for many years has seen more problems and knows how to solve them fast. Ask how long they have been in business and what kind of jobs they do most.

Some plumbers work on homes (residential plumbing). Others focus on commercial plumbing. Many also have specialized plumbing services, like:

• Drain cleaning service
• Sewer line repairs
• Water heater installation
• Backflow prevention systems
• Bathroom and kitchen renovations

Choose a plumber whose skills match your needs. For example, if you have a clogged main drain, hire someone with camera inspection and hydro-jetting tools.

3. Can You Share Customer Reviews or References?

A plumber’s reputation tells you a lot. Ask for recent customer testimonials and reviews. Check online plumbing company reviews on trusted sites. Look for:

• Many positive reviews
• Details about good communication and service
• Repeat customers
• Comments about clean-up after the job

If a plumber refuses to share references, be careful. A good plumber is proud of their work and happy to show proof. They often show it on their website as well, for example, on the Yess Boss Plumber website, their reviews are posted for full transparency:

4. How Do You Price the Job? What’s in the Estimate?

Unexpected costs are one of the biggest frustrations homeowners face when hiring tradespeople. The best way to avoid surprise bills is to get a clear, written estimate before work begins.

Your estimate should break down:

• Labour costs
• Materials
• Timeline for completion
• Additional fees (permits, disposal, clean-up)

Ask whether they charge a flat rate or an hourly rate, and clarify how after-hours or weekend work is billed. If a deposit is required, find out the amount and when the balance is due.

Also, ask how they handle unexpected issues, will they pause the job and seek your approval before adding costs, or simply proceed? A trustworthy plumber will always communicate before changing the agreed-upon scope or price.

5. Do You Offer a Warranty?

A solid warranty is a sign that a plumber stands behind their work. It gives you peace of mind that if something goes wrong soon after the repair or installation, you won’t be stuck paying for it again.

Ask for a written warranty covering both parts and labour. Clarify how long it lasts, 30 days, six months, a year, or more, and whether there are any exclusions. For example, will improper use void the warranty? Are parts covered under the manufacturer’s warranty only?

A professional plumber should be confident enough in their skills and materials to guarantee them.

6. Do You Offer Emergency Plumbing Service?

Plumbing emergencies rarely happen at convenient times. A burst pipe at midnight or a sewer backup on a holiday needs immediate attention.

Ask whether the plumber offers 24/7 emergency service and what their typical response time is. Also, inquire about after-hours rates, so you know what to expect if you need urgent help.

Knowing in advance that your plumber can respond quickly, and what it will cost, will save you from panic in a crisis.

7. Who Will Do the Work? Will You Clean Up?

Ask if the plumber you speak to will do the work or if they will send someone else. If it’s someone else, ask if they are licensed and insured.

Also ask if they include clean-up after the job. A professional plumber will wear boot covers, protect your floors, and leave your home clean.

8. Do Plumbers in Toronto Need Permits and Follow Local Plumbing Codes?

Toronto has specific plumbing codes. Some jobs need a permit. Ask if your plumber knows these rules and will handle any needed permits.

This is important for safety and for meeting the Ontario Building Code. It can also protect your home’s value if you sell later.

9. Should You Get Multiple Quotes from Toronto Plumbers?

Yes. Comparing quotes from multiple plumbers is smart. It helps you see the average cost and spot prices that are too low or too high.

But do not look at price alone. Check what is included:

• Quality of materials
• Warranty terms
• Years of experience
• Reviews and references

Sometimes a higher price is worth it if it comes with better parts, longer warranties, and skilled work.

Extra Tips for Hiring the Best Plumber in Toronto

Here are a few more smart steps:

• Visit their physical location vs. PO box if you can. This shows they are an established business.
• Test their communication and customer service skills before hiring. Do they answer calls quickly? Do they explain things clearly?
• Ask if they work on both residential vs. commercial plumbing.
• If you need specialized plumbing services, make sure they have the tools and training.
