Most Houston homeowners don't think about their pipes until something goes wrong. A slab leak, rust-colored water in the morning, or weak pressure at every faucet — these are signs your supply lines may be near the end of their life. A whole-house replumb replaces all of them at once, so you stop patching problems one at a time.
If you got a quote and you're not sure what actually happens next, you're not alone. Knowing the process helps you plan around the work and ask the right questions before a crew ever steps foot in your home.
Below, we cover timeline, pipe material, drywall, permits, and what the finished job feels like. If you're already ready to talk next steps, our team handles plumbing repair in Houston around the clock at (713) 812-7070.
A whole-house replumb in Houston typically takes one to three days for a standard home. The crew shuts off your water supply, removes the old pipes, and runs new PEX or copper lines through your attic, walls, or both. Expect some drywall cutting — this is a normal part of the process. Once the new lines are in, your plumber restores water, pressure-tests the system, and schedules a city inspection. The City of Houston requires permits and inspections for repiping work. Ask upfront who handles drywall patching and whether that cost is included in your quote.
For most Houston homes around 2,000 square feet, a whole-house replumb takes one to three days of active work. Larger homes or those with more complex layouts may run longer. Your water will be off during work hours each day and restored each evening when possible.
Slab homes — which are common across Spring, Kingwood, Humble, and The Woodlands — can add time depending on how the new lines are routed. Attic rerouting is often faster than tunneling under the slab. Ask your plumber for a daily work schedule before the job begins so you can plan accordingly.
| Home Type | Estimated Time |
|---|---|
| 2,000 sq ft, single-story slab | 1–2 days |
| 2,000 sq ft, two-story | 2–3 days |
| Complex layout or slab tunneling required | 3+ days |
PEX is the most common choice for whole-house replumbs in Houston today. It runs through attics with fewer joints than copper, which means fewer points where a leak can develop. It also handles Houston's hard, mineral-heavy water well and typically costs less in both materials and labor.
Copper still has a long track record and meets Texas code. Some homeowners prefer it for its history of durability. The right choice depends on your home's layout and your plumber's assessment — not habit or assumption.
A few things worth knowing about each option:
In our experience repiping Houston homes, attic rerouting with PEX reduces long-term callbacks. Fewer joints in the line mean fewer spots that can fail years down the road.
Some drywall cutting is always part of a whole-house replumb. This is not a sign of poor workmanship — it is how the crew accesses your existing lines and routes new ones. Access points are typically small and placed strategically, not full-wall removal.
Attic rerouting, which is common in Houston slab homes, reduces the number of wall cuts needed. Your crew works from above whenever the layout allows. This keeps disruption to your living space as low as possible.
Before work starts, ask your plumber two questions:
Here is what falls within normal range during a replumb versus what should raise a question:
| Normal | Worth Asking About |
|---|---|
| Small access cuts at fixture locations | Large sections of wall removed without explanation |
| Attic access for new line routing | No photo documentation before walls close |
| Dust and debris in work areas | Drywall closed before city inspection |
Most homes across Spring, Kingwood, Humble, The Woodlands, and Atascocita sit on a concrete slab. Your drain lines run under or through that slab. When supply lines age or drain lines fail, the slab becomes the central challenge of any replumb.
Houston's clay soil shifts with moisture changes throughout the year. That movement puts constant stress on pipe joints and connections beneath the slab. Many homes built in the 1970s through 1990s already have weakened joints long before any visible leak appears.
When slab work is involved, your plumber has two main options:
| Option | What It Means | Trade-Off |
|---|---|---|
| Tunnel under the slab | Crew digs access beneath the foundation | More labor and equipment; slab stays intact |
| Attic reroute | New supply lines run through the attic instead | Avoids slab disturbance; fewer wall cuts |
We see the tunneling vs. reroute decision come up frequently in homes across Spring and Kingwood. Slab movement in these areas has often already stressed the joints before a homeowner notices anything. Local experience with Houston slab construction changes how a crew approaches the job.
The difference is noticeable from the first morning. Consistent water pressure at every fixture, no rust or discoloration when you run the tap, and no more slow drains traced back to deteriorating pipes. Most Houston homeowners say the job was less disruptive than they expected going in.
A completed replumb also changes your position at resale. New pipes are a documented selling point. Buyers and their inspectors respond differently to a home with a permitted, inspected replumb on record versus one with aging polybutylene or corroded copper still in the walls.
Here is what life looks like on the other side of the job:
A homeowner in The Woodlands told us after their replumb that they didn't realize how much they had adjusted to the low pressure — until the morning after the job was done.

Most Houston homes around 2,000 square feet take one to three days. Slab homes in areas like Spring, Kingwood, or The Woodlands may run longer depending on whether attic rerouting or tunneling is required.
PEX is the most common choice for Houston replumbs today. It handles the city's hard water well, runs through attics with fewer joints, and costs less in materials and labor. Copper is still code-compliant and durable — your plumber's recommendation should be based on your home's layout, not habit.
Some drywall cutting is normal and expected. Attic rerouting reduces wall cuts significantly in Houston slab homes. Ask your plumber before work starts who handles patching and whether restoration is included in your quoted price.
Yes. A permit is required in Houston and most surrounding municipalities. Your plumber pulls the permit before work begins and a city inspector signs off after pressure testing — before any drywall is closed. Unpermitted work creates complications at resale.
Most Houston homes sit on a concrete slab, which means drain lines run under or through the foundation. When those lines fail, your plumber will either tunnel beneath the slab or reroute new supply lines through the attic. Clay soil movement across Houston accelerates joint stress, especially in homes built between the 1970s and 1990s.
