Water Main Repair in Greater Vancouver

A damaged water main can cause serious disruption, from low water pressure to flooding on your property, and it is not always obvious where the problem is coming from. Gold Star Plumbing and Heating diagnoses and repairs water main problems across Metro Vancouver, including Burnaby, Coquitlam, Port Coquitlam, Port Moody, and the North Shore. Whether your water main has a small leak or has failed completely, our licensed plumbers can find the source of the problem and get your water supply back to normal.

Water main repair is one of the services included in our full range of plumbing services.

Signs of a Water Main Problem

A cracked or collapsed water main can cause discoloured or gritty water throughout your home, since sediment and debris can enter the line through the damaged section. If you notice more than one of these signs together, it is worth having a plumber inspect the line before the problem gets worse.

Watch for these signs:

  • Sudden drop in water pressure throughout the home
  • Water pooling in the yard with no clear source
  • An unusually high water bill
  • The sound of running water near your water meter
  • Discoloured or gritty water coming from taps
  • A soft or sunken area in the lawn near the water line

What Causes Water Main Damage

Water mains can fail because of age, corrosion, ground shifting, tree root intrusion, or extreme temperature changes. Older homes with original water main pipe, often made of galvanized steel or early plastic materials, are more likely to run into problems as the pipe ages and weakens over time. Nearby construction or excavation work can also disturb or damage a water main that was previously in good condition. Cold winters can be particularly hard on water mains that are not buried deep enough, since freezing ground can shift and stress the pipe until it cracks.

Repair or Full Replacement

Depending on the location and extent of the damage, some water mains can be repaired, while others need to be replaced. We diagnose the problem first and explain your options clearly, including cost and expected timeline, before recommending a path forward. A small, isolated leak in an otherwise sound line can often be repaired without disturbing the rest of the pipe. A water main that has failed in multiple spots, or one made from outdated materials prone to repeat problems, is usually a better candidate for full replacement, since patching an old line again and again ends up costing more over time.

How We Locate the Problem

Finding the exact location of a water main issue is often the hardest part of the job. We use a combination of pressure testing, listening equipment, and camera inspection to trace the line and pinpoint where the damage is, rather than digging blindly and hoping to find it. This approach saves time and limits how much of your yard or driveway needs to be disturbed. Once we know exactly where the problem is, we can give you an accurate quote and a realistic idea of how much excavation, if any, the repair will require.

Water Main Materials and Upgrades

If your water main needs to be replaced, we typically recommend modern materials such as copper or high density polyethylene pipe, both of which resist corrosion and last significantly longer than the older galvanized steel commonly found in older homes. Upgrading your water main is also a good opportunity to increase pipe size if your home has always struggled with low water pressure, since an undersized line can be a hidden cause of pressure problems throughout the house.

Our Water Main Repair Process

We start by locating the source of the problem, which may involve checking pressure, tracing the line, or a camera inspection. Once we know what is wrong, we give you a clear quote and complete the repair or replacement with as little disruption to your property as possible. Depending on the repair method, this may involve a small excavation, a trenchless repair technique, or, in less common cases, a full dig along the length of the line. We restore your yard or driveway as close to its original condition as we can once the plumbing work is complete.

1. Diagnose the Problem

We check pressure and symptoms to understand what is happening with the water main.

2. Pinpoint the Damage

We trace the line and use appropriate inspection tools to locate the damaged section.

3. Explain Options and Quote

We review whether repair or replacement makes sense and provide a clear quote.

4. Complete the Work

We repair or replace the line using the least disruptive practical method for the property.

5. Test and Restore

We test the water supply and restore the affected yard or driveway as close to its original condition as possible.

Our main water line that goes from the street to our home burst and was flooding the yard and pooling against the house. Within about 1.5 hours of calling Gold Star Plumbing they were able to have someone on site to deal with it. Mo knew exactly what to do and was able to resolve the problem, replace the pipe and get our water running again the same day. This was a big job that took the whole day so I was impressed by how quickly they were able to respond.
Response from the owner:Thanks for the great review! We’re glad we could respond quickly and get your water main line repair completed the same day. The trenchless repair worked like a charm!

Moe and Ethan from Goldstar did an amazing job for us. We had a major plumbing emergency right before we were having guests over, and Moe went above and beyond to make sure everything was finished in time so we wouldn't have any issues. Moe unclogged our bath tubs, replaced our boiler/hot water tank, and also swapped out our bathroom faucets, shut-off valves, and shower cartridges. He was extremely reliable, walked us through the limitations, and always checked in with us before moving forward with any work. When we still had a small heating hiccup after the initial install, Moe sent Ethan right over. Ethan tested everything thoroughly and replaced a faulty part under warranty with zero extra charges. Thanks to both of them, we had zero hot water interruptions and our guests had a wonderful stay. Highly professional team — 5 stars all around!
Response from the owner:Geraldo it was a pleasure serving your household! From beginning to end we at gold star plumbing and heating take pride in our Troubleshooting, repair and installation of hot water heaters. We’re glad we would explain everything step by step for you and work hard to resolve all issues. Thanks for the great review!

My main water line was leaking, and I initially hired another plumbing company to begin the repair. As the work progressed, I became increasingly concerned about some of their recommendations and felt that I might be paying for additional repairs that were not actually necessary. That’s when I called Mo at Goldstar Plumbing. Even though it was late in the evening, Mo came to my home with his tools and camera equipment and took the time to thoroughly inspect the problem. He carefully explained what he found and gave me the reassurance I needed to make an informed decision. I found Mo to be knowledgeable, honest, and trustworthy. I really appreciated that he took the time to properly assess the situation rather than simply recommending more work. I would definitely recommend Mo and Goldstar Plumbing to anyone looking for a reliable and honest plumber.
Response from the owner:Hi Chris, thank you for the kind review! We’re glad we could help out with your broken water main line leak and provide our expertise. We take pride in thorough plumbing repairs and inspections. We truly appreciate your trust and recommendation

Gold star plumbing completely saved my basement during the recent thunderstorms in Vancouver. My basement started flooding due to all the rain and Gold Star was able to come to my house at 2am and found that my sump pump stopped working. They replaced it and got rid of all the excess water super quick. I tried calling a couple other plumbers but none were able to make it as fast as these guys were. I Highly recommend their services!!
Response from the owner:Happy to say we got there in time before there was too much damage! Goodluck to you Mr.Kwan and thank you for the review means a lot to work in the Killarney area

Frequently Asked Questions

A sudden drop in water pressure throughout the home, pooling water in the yard, or a spike in your water bill are all signs that point toward the water main rather than a single fixture.

It depends on the location and type of repair needed. Some repairs use trenchless methods that limit digging, while others require a small excavation. We will explain what to expect for your specific situation before starting any work.

A leaking or damaged water main can get worse over time and lead to more water loss and property damage, so it is worth having it looked at promptly rather than waiting.

We use pressure testing, listening equipment, and camera inspection to trace the line and pinpoint the damage before we start digging, which helps limit disruption to your property.

We typically recommend copper or high density polyethylene pipe, since both resist corrosion and last significantly longer than older galvanized steel lines.

In most cases, yes, for the duration of the repair. We will let you know how long to expect your water to be off before we begin.
