When something goes wrong with your home’s plumbing system, your first instinct might be to fix it yourself—or hire the first available contractor. But plumbing is more complex (and more important) than many people realize. A poor repair job can lead to water damage, mold, and costly repeat work. So, how do you hire a professional plumber you can actually trust?

This guide walks you through what to look for, how to compare your options, and why choosing a licensed local plumber is one of the best decisions you can make for your home and peace of mind.

Why Hiring a Licensed Plumber Matters

Hiring a licensed plumber means you’re working with someone who’s been officially trained, tested, and certified to handle plumbing tasks in your area. Licensing ensures the contractor follows local plumbing codes and safety regulations.

A licensed plumber has:

• Passed provincial or municipal certification exams

• Liability insurance to protect you in case of damage

• A commitment to doing the job safely and properly

• The legal authority to perform major repairs and installations

A licensed plumber in Ontario typically completes a multi-year apprenticeship and technical training, as outlined by Skilled Trades Ontario. This makes them far more qualified than general handymen or unlicensed contractors.

Unlicensed or underqualified plumbers may offer cheaper rates, but they can create expensive problems down the line—especially if work isn’t up to code or if a warranty becomes void.

Why a Local Plumber Is Often the Best Choice

If you’re wondering how to hire the right plumber, one of the best things you can do is hire local.

A local plumber:

• Responds quickly to emergencies

• Understands your region’s plumbing systems and common issues

• Relies on reputation and repeat business in the community

• Is more accessible for follow-up service or maintenance

At Best Plumbing and Drainage Contractors, we believe that choosing a licensed, local expert gives you the fastest, most reliable results—along with the peace of mind that comes from working with someone who truly cares about your home.

How to Hire a Professional Plumber: Step-by-Step Guide

1. Verify Licensing and Insurance

This is non-negotiable. Ask the plumber for their license number and check that it’s valid in your province. Also ask for proof of insurance so you’re not liable if anything goes wrong during the job.

Tip: In Ontario, you can verify a plumber’s license through the Skilled Trades Ontario website or by contacting your municipality. In other provinces, check with your provincial trade authority or confirm if the plumber holds a Red Seal Certification, which is recognized nationwide.

2. Ask About Experience

Find out how long they’ve been in business and whether they specialize in residential, commercial, or both. More experience usually means faster diagnosis, better workmanship, and fewer surprises.

3. Read Online Reviews and Ask for References

Search Google, Yelp, or local directories for honest reviews. Pay attention to how the company responds to feedback. You can also ask for direct references from past clients.

4. Request a Detailed Estimate

A professional plumber will offer a clear, written quote before any work begins. It should include labor, materials, timelines, and any applicable warranties. Avoid vague pricing or verbal-only quotes.

5. Check What’s Included in the Service

Some plumbing jobs might involve permits, disposal of old materials, or testing after installation. Make sure these are included—or at least discussed—up front.

What Services Should a Licensed Plumber Offer?

Whether you’re hiring a plumber for a small leak or a full system upgrade, they should be able to handle:

• Drain cleaning and unclogging

• Leak detection and repair

• Fixture installation (sinks, toilets, tubs)

• Water heater repair or replacement

• Pipe repair or repiping

• Sewer line services

• Sump Pump installation or repair

• Emergency plumbing services

Many homeowners start with a small issue—like a slow drain—and end up discovering deeper concerns. That’s why a skilled licensed plumber is so valuable: they can spot and solve problems before they escalate.

Common Plumbing Problems That Require a Professional

Persistent Leaks

Even a slow drip can waste hundreds of litres of water per month and lead to water damage.

Toilet Running Constantly or Backing Up

This may indicate a worn-out flapper, a faulty fill valve, or a deeper clog in your sewer line.

Low Water Pressure

This often signals corroded pipes or hidden leaks—something a professional can diagnose with specialized tools.

Hot Water Issues

Fluctuating temperatures or a lack of hot water may point to a failing water heater or sediment buildup.

Foul Smells from Drains

This could mean a blocked vent pipe or sewer gas leak—both issues that require expert attention.

Long-Term Benefits of Hiring a Licensed Local Plumber

Hiring a licensed local plumber isn’t just about solving today’s problem. It’s about protecting your home long-term. Here’s why it pays off:

Reliable Workmanship

Licensed plumbers follow code and best practices, so their work lasts longer and performs better.

Preventative Advice

Professionals can help you prevent future issues with regular maintenance tips or early detection of warning signs.

Increased Home Value

A well-maintained plumbing system adds value to your home, and buyers feel more confident knowing a professional handled the work.

Reduced Risk of Water Damage

Mistakes from amateur repairs can lead to water leaks behind walls, mold growth, and costly cleanup. Professionals help you avoid that risk entirely.

When to Call a Plumber Immediately

If you experience any of the following, don’t delay:

• A burst pipe

• A backed-up sewer line

• No hot water

• A sudden drop in water pressure

• Water stains on walls or ceilings

These are emergency situations where hiring a licensed plumber immediately can save you thousands of dollars in repairs and damage.

Final Thoughts: Hiring the Right Plumber Starts with Knowing What to Look For

When it comes to your home’s plumbing system, cutting corners just isn’t worth it. By hiring a licensed local plumber, you’re ensuring the job is done right, safely, and up to code. You’ll save time, reduce stress, and avoid future issues that could cost you much more in the long run.
