With a crew carrying decades of combined experience in waterline work, the first question is never 'replace or repair' — it's where the leak actually is. Acoustic listening equipment and ground radar locate it without digging up the yard to find out, and trenchless technique keeps the excavation to the section that actually needs it rather than the whole run. Modern Drainage's own administrative staff handle the permit and the coordination with the utility, because a service line repair touches infrastructure that isn't only yours.

Dom and his team are absolute stars. The water supply piping failed to our strata yesterday evening. They identified the problem, got the parts and fixed by noon today. I've used them several times and always had a great experience. First rate

What to check, and what to ask

General guidance for homeowners, not specific to your system — worth knowing before you book anyone, including us.

  1. Low pressure everywhere and one weak fixture are different problems

    Pressure that has dropped house-wide points toward the service line itself. A single fixture that has always been weak more often points at that fixture or its own supply line. Note which one you actually have before a diagnosis is quoted.

  2. Sound-based leak detection exists before excavation

    Acoustic equipment can often locate a leak in a buried water line by listening for it along the pipe's length, narrowing where a dig actually needs to happen rather than opening the whole run. Ask whether this step is offered before a location is quoted.

  3. Trenchless repair is not available for every situation

    Depending on the pipe material, depth and what is above it, a water line can sometimes be repaired or replaced without a full open trench. Ask what makes a property a trenchless candidate rather than assuming it always applies.

  4. The utility side of the paperwork is not yours to chase

    A water main repair or replacement generally needs a permit, and the utility itself may need to be involved at the property line. A contractor who manages that coordination is handling work that is genuinely hard for a homeowner to do alone.

Try these first

  1. 1. Read the water meter with everything off

    Turn off every fixture in the house, wait a few minutes, then check the meter's leak indicator. If it is moving, note it — that is real evidence of where to start looking.

  2. 2. Check a hose bib with a pressure gauge, if you have one

    An inexpensive gauge threaded onto an outdoor tap gives an actual number. Whether it is low everywhere or normal at some fixtures and not others is useful to know before anyone arrives.

  3. 3. Look for a wet patch on the lawn or driveway

    A soft, unusually green patch, or water pooling on pavement with no obvious source, can point at roughly where a buried leak is. Note the location without digging.

  4. 4. Work out whether it is one fixture or the whole house

    Low pressure at a single tap points one way; low pressure everywhere, all at once, points another. This is one of the fastest things to establish yourself.

  5. 5. Check your water bill against a typical month

    An unexplained jump with no change in usage is a real signal for a hidden main leak, and it is already sitting in your account if you look.

Before you call

Why do I have water bubbling up in my front lawn?
If you notice water bubbling or a large wet spot on your property it is most likely the result of a leaking waterline.
Should I repair or replace my water line if it's leaking?
Replacing your line is not always necessary, nor recommended. Depending on the age and composition of your pipe, and the location and the severity of the leak, it can often be repaired for a smaller cost. Our estimators will provide honest advice about which solution is best for your situation.
