Question 1

Are you licensed and insured?

Accepted Answer

Yes. Every Jumbo Plumbing technician is fully licensed, insured, and background-checked. We do not cut corners on credentials any more than we cut corners on the job.

Question 2

What areas do you serve?

Accepted Answer

We serve St. Thomas, London, and Southwestern Ontario including Aylmer, Woodstock, Tillsonburg, Dutton, Mount Brydges, and surrounding communities.

Question 3

How quickly can you respond?

Accepted Answer

For emergencies, we aim to be on-site within the hour. For scheduled service, we offer same-day and next-day appointments in most cases.

Question 4

Do you offer warranties on your work?

Accepted Answer

Yes. All our work comes with a workmanship warranty. Parts warranties vary by manufacturer. We will explain everything before we start.

Question 5

What makes Jumbo Plumbing different from other plumbers in St. Thomas and London?

Accepted Answer

A few things. We answer the phone ourselves — 24 hours a day. We charge a transparent dispatch fee instead of burying travel costs in inflated job prices. Every technician is licensed, insured, and background-checked. We offer protection plans that actually cover repairs. And we back everything with a real workmanship warranty. We are not a call centre that dispatches strangers. We are a local team that shows up and stands behind the work.

Question 6

Do your plumbers show up on time?

Accepted Answer

We respect your time. You will always receive a heads-up call before we arrive and a clear arrival window when you book. For emergency calls, we move fast — most of the time you will see us well within the hour.

Question 7

Are Jumbo Plumbing technicians background-checked?

Accepted Answer

Yes. Every technician on our team is thoroughly background-checked before they set foot in a customer home. You are letting us into your house — that matters to us as much as it matters to you.

Question 8

How does your pricing work?

Accepted Answer

We provide upfront, transparent quotes before any work begins. No hidden fees. No surprise charges. You approve the price, then we work.

Question 9

What is the $79 dispatch fee?

Accepted Answer

Our $79 dispatch fee covers a licensed technician traveling to your home and performing a thorough assessment. Not a 30-second look, but a proper, professional diagnosis of the issue with a clear, fair quote. Here is the key part: the fee is only charged if you decide not to move forward with the service. If you book the repair, it is on us. You only pay for the job itself.

Question 10

Why do you charge a dispatch fee at all?

Accepted Answer

Because a real diagnosis takes real time. Sending out a licensed professional, properly assessing your plumbing, and giving you an accurate quote is work that deserves to be done properly. Fake free estimates often lead to inflated job prices. We would rather be honest: $79 for a professional assessment, waived completely if you move forward. Most of our customers consider it the best $79 they almost spent.

Question 11

How much does it cost to fix a leaking pipe in Ontario?

Accepted Answer

Every leak is different. The location, severity, and accessibility all affect the scope of work. A minor accessible pipe repair is a very different job from a hidden leak inside a wall or under a slab. That is exactly why we send a licensed technician to properly assess before quoting — the only accurate price is one based on what our tech actually sees in person. You will always have a firm written quote before we touch anything.

Question 12

Do you offer any discounts?

Accepted Answer

Protection Plan members receive 15% off all service calls. We also offer senior discounts. Just ask when you call. Additionally, qualifying water heater upgrades (tankless and heat pump units) may be eligible for rebates through federal and utility programs — check current amounts directly with the providers below.

Question 13

What payment methods do you accept?

Accepted Answer

We accept all major credit cards, debit, e-transfer, and cash. Payment is due upon completion of work.

Question 14

Is there a 24-hour plumber in St. Thomas or London, Ontario?

Accepted Answer

Yes — that is us. Jumbo Plumbing answers the phone 24 hours a day, 7 days a week, every single day of the year including holidays. When you call at 2am with a burst pipe or a flooded basement, a real person picks up and we get moving. No voicemail, no call centre, no waiting until morning.

Question 15

Do you really answer 24/7?

Accepted Answer

Yes. A real person answers the phone 24 hours a day, 7 days a week, 365 days a year. No voicemail. No answering service. Just us.

Question 16

What counts as a plumbing emergency?

Accepted Answer

Burst pipes, major leaks, sewer backups, flooding, no hot water, gas line concerns. Anything that cannot safely wait until morning.

Question 17

What should I do if my basement is flooding?

Accepted Answer

First, shut off your main water valve immediately — it is usually near your water meter or where the main line enters the home. If the flooding is from a sewer backup, do not use any drains or toilets. Do not use electrical devices near standing water. Then call us right away. We will talk you through next steps on the phone while we get a technician moving to your location.

Question 18

Is there an extra charge for after-hours calls?

Accepted Answer

After-hours and weekend rates may apply. We will always tell you the rate before dispatching so there are no surprises.

Question 19

What should I do while waiting for you to arrive?

Accepted Answer

Shut off the main water valve if there is a major leak or burst pipe. For gas issues, leave the building and call 911 first, then us.

Question 20

Can a burst pipe cause serious damage to my home?

Accepted Answer

Absolutely — and fast. A single burst pipe can release hundreds of litres of water in minutes, causing structural damage, mold growth, and ruined flooring, drywall, and belongings. That is why speed matters. Shutting off your main water valve immediately limits the damage, and having a plumber on-site quickly makes a huge difference in what you will face afterward.

Question 21

Can you fix a dripping faucet or running toilet?

Accepted Answer

Yes — and it is worth fixing sooner than most people think. A running toilet can waste thousands of litres of water per month, and a dripping faucet adds up fast on your water bill. These are quick jobs for us, and we will give you an honest quote before we start.

Question 22

Do you offer drain cleaning and clog removal in St. Thomas and London?

Accepted Answer

Yes. We handle everything from slow drains and kitchen blockages to main sewer line clogs. We use professional-grade equipment to clear the line properly, not just punch a temporary hole through the buildup. We serve St. Thomas, London, and all surrounding areas in Southwestern Ontario.

Question 23

Can you find a hidden water leak without tearing up my walls?

Accepted Answer

In many cases, yes. We use leak detection equipment to locate the source of a leak before recommending any repairs. This often saves significant time and cost compared to exploratory cutting. We will always tell you what we found and what it will take to fix it before any work begins.

Question 24

Do you install and service sump pumps?

Accepted Answer

Yes. We install, repair, and replace sump pumps for residential properties across St. Thomas, London, and Southwestern Ontario. If your sump pump is failing or you want a backup unit for added protection, we can assess and handle it same-day in most cases.

Question 25

Are there city grants available for sump pump installation in St. Thomas or London?

Accepted Answer

Yes — and they are significant. Both the City of St. Thomas and the City of London run basement flooding grant programs that reimburse up to 90% of eligible work. St. Thomas offers up to $5,750 total (up to $4,000 for sump pump and weeping tile disconnection, up to $1,800 for a backwater valve). London's program covers up to 90% across multiple eligible work categories including sump pump installation, backwater valves, and window well covers. Important: you must apply and receive approval before any work begins — retroactive applications are not accepted. Our full guide walks through both programs, eligibility rules, and how to apply.

Question 26

Can you do new construction plumbing?

Accepted Answer

Absolutely. We work with builders and contractors on new residential construction projects throughout the region.

Question 27

Do you do sewer camera inspections?

Accepted Answer

Yes. We use professional-grade camera equipment to diagnose sewer and drain issues with precision before recommending any repair.

Question 28

Can you install a new water heater?

Accepted Answer

Yes. Same-day installation in most cases. We carry major brands and can recommend the right unit for your home or building.

Question 29

Do you offer fixture installation and upgrades in St. Thomas and London?

Accepted Answer

Yes. We install and replace faucets, toilets, showers, bathtubs, sinks, and all related fixtures. Whether you are doing a bathroom renovation or just upgrading an old fixture, we handle the installation properly so it is done once and done right.

Question 30

What is a Protection Plan?

Accepted Answer

A Jumbo Protection Plan is a monthly membership that gives you preventative maintenance, priority service, and repair savings. We offer three tiers: Silver, Gold, and Platinum.

Question 31

What are the Protection Plan tiers?

Accepted Answer

We offer three tiers: Silver, Gold, and Platinum. Silver is our entry-level plan and includes discounts on minor repairs and all services, VIP priority scheduling, annual water heater flushing, camera inspection, annual plumbing inspection, and unlimited evaluation and diagnostics. Gold (most popular) upgrades to free unlimited minor repairs, unlimited waived after-hours fees, VIP scheduling, and special member pricing on all services. Platinum adds free mid-tier repairs on top of everything in Gold. Visit our Protection Plans page for current pricing on each tier.

Question 32

What qualifies as a minor or mid-tier repair?

Accepted Answer

Minor repairs include things like toilet flapper replacements, faucet cartridge swaps, minor drain clearing, and small fixture adjustments. Mid-tier repairs covered under Platinum include more involved work such as supply line replacements, valve replacements, and similar repairs. A full list of qualifying repairs by category is available. Just ask when you enroll.

Question 33

Is a plumbing maintenance plan worth it for homeowners in Ontario?

Accepted Answer

For most homeowners, yes. A single avoided emergency call pays for months of membership. Beyond the cost savings, the real value is catching problems before they become expensive — a cracked supply line, a corroding valve, a failing water heater. Our annual inspections give you a written report of your entire plumbing system so nothing sneaks up on you.

Question 34

How often should I have my plumbing inspected?

Accepted Answer

At minimum, once a year. Plumbing in Ontario deals with hard water, freezing temperatures, and aging infrastructure. An annual inspection by a licensed plumber catches early signs of corrosion, pressure issues, water heater wear, and sewer line buildup before they turn into emergencies. All Jumbo Protection Plan members receive a full annual inspection included in their membership.

Question 35

Can I cancel my Protection Plan?

Accepted Answer

Yes. Plans are monthly and can be cancelled with 30 days notice. There are no long-term contracts. We earn your membership every month.

Question 36

What is included in the annual inspection?

Accepted Answer

A full plumbing system check including water heater flush and safety valve test, sewer camera inspection, all supply and drain lines, fixtures, shutoff valves, and water pressure. We catch problems before they become disasters and provide a written report after every visit.
