Whole Home Repiping in Lawrenceville
What repiping is and when it makes sense
Repiping means replacing the water supply pipes inside a house. The old pipes come out or are abandoned in place, and new pipe is run to every fixture. This is different from fixing a single leak: it is the answer when the pipe itself is failing or when repeated repairs are adding up.
This site is a referral line. We do not employ plumbers and do not do the work. Call (770) 285-5619 and we connect you with an independent local plumber who handles repiping. The plumber walks the house, explains the plan and gives you the price. Ask for the price before any work starts.
Signs your home may need repiping
- Repeated leaks in different spots, not just one
- Gray, blue or black flexible plastic pipe (polybutylene)
- Rusty or brown water, especially after the water has sat unused
- Low pressure at several fixtures, not just one
- Pipes that are gray steel with threaded joints (galvanized)
- Green or blue stains and pinhole leaks on copper
- An inspection or insurance company that flagged the pipe
What Is in the Walls: Pipes by Era in Gwinnett Homes
Housing age tells you where to look
Lawrenceville has homes from several different building booms, and each used different supply pipe. Your house may not match the general pattern, but this is a good starting point.
Early 1900s to the 1960s
Older houses near downtown Lawrenceville and the older streets around it often have galvanized steel supply pipe, sometimes with cast iron drains. Corrosion inside the pipe slowly cuts flow.
1970s
A mix. Copper was common, but polybutylene began showing up in late 1970s homes. Some houses have both.
1980s to mid 1990s
Gwinnett grew quickly in these years. Polybutylene shows up in some builds of this period, with copper in others. Houses with PB pipe often have it in the manifold and under sinks.
Late 1990s to 2000s
Copper and CPVC were widely used. Copper from this era can start to pinhole where the water chemistry is aggressive. CPVC can become brittle with age.
2010s and newer
PEX is the standard. These houses rarely need repiping, and problems are usually isolated fittings.
Polybutylene in Gwinnett Homes
The pipe that gets flagged at closing
Polybutylene (PB) is a gray, sometimes blue or black flexible plastic pipe. It was installed in many homes from the late 1970s to the mid 1990s because it was cheap and quick to put in. It has a reputation for failing at fittings, especially the crimped joints, and for splitting without warning. Many insurers ask about it and many home inspectors flag it.
- How to spot it: flexible gray, blue or black pipe, often stamped PB2110, with metal crimp rings or plastic fittings, where the line enters the house, near the water heater and under sinks.
- What it does: fittings can fail, and the pipe can become brittle on the inside from water chemistry. A leak in the wall can be sudden.
- What to do: have a plumber confirm what you have and look at how much is in the house. If it is throughout, repiping is the lasting answer. Related: burst pipe repair.
Galvanized Pipe in Older Lawrenceville Houses
Rust you cannot see
Galvanized steel pipe is coated with zinc. The coating wears away and the steel rusts from the inside. That narrows the opening, reduces flow and flakes rust into the water. In older Lawrenceville houses, galvanized lines may still be in the walls and crawlspace, often mixed with newer copper from past repairs.
- Signs: low pressure that gets worse over time, rusty or brown water when you first turn on a tap, leaks at threaded fittings.
- The mixed-metal problem: connecting galvanized to copper without proper fittings speeds up corrosion at the joint.
- The test: a magnet sticks to galvanized steel but not to copper or plastic. A plumber can also show you the inside of a cut section.
PEX or Copper: Choosing the New Pipe
What to ask the plumber
PEX
Flexible plastic pipe that runs through walls and attics with fewer fittings. It is common in newer Gwinnett builds, resists freezing damage better than rigid pipe, and does not corrode. It should not be left in sunlight and some connectors are a weak point.
Copper
A long track record, rigid, fire-resistant and reliable where installed well. Copper can pinhole in some water conditions and takes more time to install than PEX.
CPVC
A rigid plastic sometimes used in newer homes. It can become brittle with age and temperature, so many plumbers prefer PEX or copper for a repipe.
What to ask
Why they chose that material for your house, what the fittings are, where the manifold or valves will go, and how the lines will be supported and protected.
What a Repipe Involves
From the walkthrough to the final test
- Walkthrough and plan. The plumber looks at the attic, crawlspace or basement, counts fixtures and decides how to route new lines.
- Permit. Whole-house repipes normally need a permit and an inspection through the city or county, depending on your address.
- Water off. The water is shut off while lines are swapped. Ask about the schedule and plan for no water during the work.
- Rough-in. New lines are run to each fixture, usually through attic, crawlspace or garage areas, with some wall openings where needed.
- Reconnect and test. Fixtures and the water heater are reconnected, and the system is pressure tested.
- Inspection and patching. The inspector checks the work. Drywall repair and paint are often a separate step. Ask who handles them.
In slab-on-grade houses, new lines are often run overhead and the old slab lines are abandoned. See slab leak repair for how that works.
Repiping Cost: What Moves the Number
What changes the price
- Size of the house and number of bathrooms and fixtures
- Pipe material chosen
- Access: open attic and crawlspace versus finished walls
- Slab versus crawlspace construction
- Drywall, paint and flooring repairs
- Permit and inspection requirements
- Whether the water heater lines and shutoffs are updated at the same time
This site does not set prices and does not promise how a plumber prices. Ask for the price before any work starts, in writing, and ask what is included for drywall repair.
Repipe or Repair: How to Decide
A short checklist
- Repair if one leak, in good pipe, in an easy spot.
- Consider a partial repipe if one section, such as a crawlspace run, is the problem.
- Consider a whole home repipe if the pipe is polybutylene or galvanized, if you have had three or more leaks, or if you plan to stay in the house for years.
- Before you decide, ask for a written description of what the plumber found and why they recommend it. Compare it to the signs in our guide signs you need to repipe your Lawrenceville home.
If the leak is outside the house, it may be the water service line instead. See water line repair. To find where a leak is hiding first, see leak detection.
Repiping in Lawrenceville and Gwinnett County
Where the independent plumbers on this line work.
Water Supply
Gwinnett County Department of Water Resources supplies most of the county, including most Lawrenceville addresses. Buford runs its own water system. After a repipe, the plumber works on the house side of the meter.
Insurance and Resale
Many insurers ask about polybutylene and some price policies around it. Home inspectors also flag it. Keep the plumber's written description of what was found and what was replaced.
Crawlspace and Slab Houses
Crawlspaces make repiping easier, with open access to the lines. Slab houses are usually repiped overhead through the attic.
Hard Freezes
Georgia does not freeze for long, so many supply lines run in attics and exterior walls. PEX is more freeze-tolerant than rigid pipe, but insulation still matters.
Frequently Asked Questions
Polybutylene is flexible plastic pipe, usually gray, sometimes blue or black, with markings such as PB2110 stamped on it. Look at the pipe where it enters the house, near the water heater and under sinks. It was used in some homes built from the late 1970s into the mid 1990s. A plumber can confirm it quickly.
In older houses, yes. Galvanized steel corrodes from the inside, so the opening narrows over the years. Signs are low pressure, rusty or brown water, and leaks at threaded joints. If your house predates the 1970s and the plumbing has never been updated, check what is in the walls and crawlspace.
Both are used. PEX is flexible, goes through walls and attics with fewer joints and is common in newer Gwinnett builds. Copper has a long track record, is rigid and can pinhole in some water conditions. Ask the plumber why they are recommending one over the other for your house.
It depends on the size of the house, how many bathrooms it has, how much of the plumbing is accessible and how much drywall has to be opened. Many repipes take several days; large or finished homes can take longer. Ask the plumber for a schedule and when the water will be off each day.
Some openings are usually needed, but a good plan keeps them small. New lines can often run through attics, crawlspaces, closets and garages, and access holes are typically patched. Ask the plumber which walls will be opened and who handles drywall and paint.
There is no single number. The cost depends on the size of the house, number of fixtures, the material, how easy the access is, and how much repair work the walls need afterward. This site does not set prices. Ask the plumber for the price before any work starts, and ask for it in writing.
Permits and inspections are normally part of a whole-house repipe, through either the city or the county depending on where the house is. Ask the plumber who pulls the permit and when the inspection happens.
Yes. A plumber can replace one run, such as the line to a bathroom or the lines in a crawlspace. A partial repipe makes sense if the rest of the pipe is in good shape. If the pipe is polybutylene or galvanized, replacing only part of it often leaves the next failure close by.
