Water Line Repair Lawrenceville, GA
The main line between your meter and your house is the one pipe that takes the whole home down when it fails. We locate, repair, and replace water service lines across Lawrenceville and Gwinnett County.
Main Water Service Line Repair
From the meter to the house, diagnosed properly
Your water service line is the single pipe carrying every gallon from the meter at the street into the house. When it develops a leak you often do not see water at all. Instead you get a water bill that jumped for no reason, pressure that dropped across the whole house, or a soft green patch in the yard that stays wet through a dry week.
Older Lawrenceville homes frequently still have galvanized steel or early plastic service lines that corrode and split with age. Gwinnett County's red clay also shifts with wet and dry cycles, which stresses buried joints. We locate the failure point precisely before digging, so you are not paying for an excavated yard to find a leak by trial and error.
Signs Your Water Service Line Is Failing:
- A sudden jump in the water bill with no change in usage
- Low water pressure throughout the entire house
- A wet, soggy, or unusually green strip across the yard
- Rusty or discolored water at every fixture
- The meter dial still moving with all fixtures shut off
- Sinkholes or soft depressions along the line's path
Our Water Line Services
Locate the fault, then fix only what needs fixing.
Underground Leak Location
Acoustic and pressure testing to pinpoint the break before any digging starts.
Spot Repair
When the line is otherwise sound, we repair the single failure point rather than replacing everything.
Full Line Replacement
Complete meter to house replacement in modern PEX or copper when the old line is past saving.
Trenchless Replacement
Where conditions allow, we pull new line through the old path and leave your yard largely intact.
Pressure Diagnosis
Low pressure is not always a leak. We test and check the regulator before recommending excavation.
New Line Installation
New service lines for additions, detached structures, irrigation, and outbuildings.
Water Lines in Lawrenceville & Gwinnett County
Local soil, local pipe age, local utility coordination.
Red Clay and Buried Pipe
Gwinnett County's clay soil expands when saturated and contracts hard in dry spells. That seasonal movement works on buried joints year after year, which is why service line failures here often show up after a wet spring followed by a dry summer rather than during a freeze.
Older Lawrenceville Homes
Homes built before the 1980s frequently still run galvanized steel service lines. Galvanized corrodes from the inside, narrowing the bore until pressure drops noticeably even before it leaks. If your home is that era and pressure has faded gradually, the service line is the first thing to test.
Where Responsibility Splits
In most cases the water utility owns the line up to and including the meter, and the homeowner owns everything from the meter to the house. We help you establish which side the leak is on before you pay for work that is not yours, which occasionally saves the entire cost of the job.
Locating Before Digging
We locate the failure acoustically and confirm with pressure testing before excavation, and we arrange utility marking first. Precise location is what keeps a service line repair to a small dig instead of a trench across the whole front yard.
Why Choose Pro Plumber Lawrenceville?
Diagnosis before excavation, every time
We Locate First
Precise electronic and acoustic location means a targeted dig, not an exploratory trench through your lawn.
Repair When Repair Is Right
If a spot repair will hold, we quote a spot repair. We do not default to full replacement because it bills more.
Yard Restoration
We backfill and restore the work area properly rather than leaving a mound of clay for you to deal with.
Permitted & Warrantied
Licensed, insured, permitted where required, and warrantied so the repair is documented for resale.
Frequently Asked Questions
Common questions about water line repair in Lawrenceville, GA.
A targeted spot repair on a water service line in Lawrenceville typically runs $500 to $1,800 depending on depth and access. A full meter to house replacement generally runs $2,500 to $6,000, with trenchless methods at the higher end but far less yard restoration. We locate the fault first and quote against what we actually find.
Shut off every fixture and appliance in the house, then check the meter. If the dial or leak indicator is still moving, water is escaping somewhere between the meter and the house. Other signs are an unexplained bill increase, whole house pressure loss, and a wet or unusually green patch in the yard.
Generally the utility owns the line up to and including the meter, and the property owner owns the line from the meter to the house. We help confirm which side the leak falls on before work starts, because if the fault is on the utility side you should not be paying for it at all.
Often yes. Where the path and soil allow, we can pull a new line through the existing route, which limits excavation to a small pit at each end instead of an open trench. We assess whether your line is a candidate during the initial location visit.
A spot repair is usually completed in a single day. A full service line replacement typically takes one to two days including utility marking, excavation, the new line, pressure testing, and backfill. We give a realistic schedule once we have located the fault and confirmed the route.
Whole house pressure loss usually points to the service line, a failing pressure regulator, or a partially closed main valve. Corroded galvanized line is a common cause in older Lawrenceville homes. We test pressure at the meter and at the house to isolate which it is before recommending any excavation.
