WHOLE-HOUSE FIX
Repiping in Dallas, GA
A home with three or more pinhole leaks in the same few years usually needs a full repipe, not another one-off patch.
Repiping means replacing a home's aging supply lines, typically galvanized steel or old copper, with modern PEX or copper throughout, rather than patching each new leak as it appears. For a lot of Dallas-area homes, especially those built before the mid-1990s closer to the original downtown square, repeated pinhole leaks are a sign the whole system has reached the end of its service life, not a run of bad luck.
We assess the whole home's plumbing before recommending a repipe, since a partial repipe of just the worst-affected sections is sometimes the more sensible and affordable option compared to replacing every line in the house.
Why older Dallas homes reach this point
Galvanized steel pipe corrodes from the inside over decades, gradually narrowing its interior diameter with rust buildup until water pressure drops noticeably, and it eventually develops pinhole leaks at random points along its length as the corrosion works all the way through. Homes built before the 1990s around Dallas's older core are the ones most likely to still have original galvanized lines, and once one leak shows up, more are usually close behind since the corrosion is uniform along the whole line's age, not isolated to one spot.
Copper doesn't corrode the same way, but it does work-harden and become brittle at points where Paulding County's expansive clay soil has flexed it repeatedly over years, which is the same mechanism behind a lot of the slab leak calls in newer copper-plumbed homes built through the 1990s and 2000s.
Is it time to repipe? A quick guide
| Situation | Usual recommendation |
|---|---|
| Original galvanized pipe, home built before 1990 | Full repipe, corrosion is uniform along the line's age |
| Two or more pinhole leaks in copper within a couple of years | Full or partial repipe depending on which sections are affected |
| One isolated leak, otherwise sound system | Targeted repair, repipe not yet necessary |
| Visibly low water pressure throughout the house | Worth inspecting for galvanized pipe corrosion |
Worth knowing
PEX versus copper for a repipe today
For most Dallas-area repipes today, PEX is the more common choice, since it flexes with the same clay-soil ground movement that eventually cracks a rigid copper joint, and it costs less to install throughout a whole house. Copper is still a reasonable choice for homeowners who prefer it, and we quote both options honestly rather than steering every job toward one material.
A full repipe also goes through Paulding County's permitting and inspection process, which is worth factoring into the timeline, and it's genuinely useful for resale on an older home near Dallas's downtown square, since a documented, permitted repipe answers the exact question a buyer's inspector is likely to raise about original galvanized plumbing before it ever becomes a negotiating point.
Signs a home may need repiping
- Rusty or discolored water, especially right after the water's been off for a while
- Noticeably low water pressure across multiple fixtures, not just one
- More than one pinhole leak discovered within a year or two

One more thing worth knowing: a home already dealing with repeated slab leak detection and repair calls on the same aging copper line is often a strong candidate for a full repipe instead of continuing to patch the same system.

Asked about repiping in Dallas
How do we know if our house has galvanized pipe?
A visual inspection at an accessible section, often in a basement, crawlspace, or utility area, usually confirms it. Galvanized pipe has a distinct gray, threaded appearance different from copper's reddish color or PEX's flexible plastic tubing.
Does a whole house need to be repiped at once, or can it be done in sections?
It depends on the home's layout and how the existing lines are run. Some homes repipe cleanly in stages, while others are more efficient to complete in one pass, and we walk through both options before recommending either.
Is PEX actually as durable as copper long-term?
Yes, PEX has a strong long-term track record and, in a market like Dallas with expansive clay soil, its flexibility is a genuine advantage over rigid copper, which is more prone to stress fatigue from repeated ground movement.
How disruptive is a repipe to daily life in the house?
It's a bigger job than a single repair, typically requiring access through walls or ceilings in stages, but a well-planned repipe keeps water off for only short windows at a time rather than the whole project.
