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:
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 A water main that has failed in multiple spots, or one made from outdated materials prone to repeat problems, is usually a better candidate for full replacement, since patching an old line again and again ends up costing more over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.
