Homeowners approving a whole-house repipe usually imagine weeks of disruption, an unlivable house, and walls left open indefinitely. The reality is considerably shorter and more contained than that, but only when the scope is clear from the beginning. Knowing what happens on each day removes most of the anxiety, and it also makes it obvious when a quote for whole house repiping has left something out.
Short Answer
A typical Houston repipe runs three to five days for the pipe work, with restoration adding a day or two after that. Day one is protection and access, day two is installing the new lines, day three is pressure testing, inspection, and tie-in, and the remaining days are drywall and paint. Most households stay in the home throughout, with water shut off during working hours and restored each evening. Home size, number of bathrooms, two stories, and attic access are what move the timeline.
Before Work Begins
The work that happens before anyone opens a wall determines how smoothly the rest goes.
A walkthrough establishes the number of fixtures, the routing available, and the condition of what is there now. Where the failing system has not been positively identified, diagnostics come first, since supply-side and drain-side problems look similar to a homeowner and call for entirely different work. Hydrostatic testing settles that question before anyone commits to a scope.
Permitting follows, along with material selection. The comparison between PEX and copper matters here because the material affects routing, the number of concealed fittings, and how the system handles foundation movement.
Your preparation is straightforward. Clear the areas under sinks and inside the water heater closet, empty closets that back onto plumbing walls, make sure attic access is reachable, move valuables and wall hangings out of work areas, and plan for pets to be somewhere quiet.
Day One: Protection, Access, and Opening Walls
The first day is mostly preparation and demolition, and it looks more dramatic than it is.
Crews lay floor protection along traffic paths and hang plastic sheeting to contain dust. The existing lines are located and marked so that access points are cut where the pipe actually runs rather than across whole walls. This is the part homeowners misjudge most: a competent repipe opens a series of targeted access points, not the entire wall surface.
Water is shut off for portions of the day. By the end of day one the house looks worse than at any other point in the project, which is worth knowing in advance.
Day Two: Installing the New Lines
New supply lines are run to every fixture in the home. In Houston, that routing usually goes overhead through the attic rather than under the slab.
That overhead approach is the standard answer for slab foundations, and it is why repeated slab leak repair eventually gives way to a repipe. Rather than tunneling under the foundation again to fix another failure, the under-slab supply lines are abandoned in place and the house is fed from above, which removes the failure point entirely rather than patching it.
Lines are run to each bathroom, the kitchen, the laundry, and the water heater, with connections made at every fixture. Valves are replaced as part of the work, which is frequently overlooked in cheaper quotes and matters the first time you need to isolate a fixture.
Day Three: Pressure Test, Inspection, and Tie-In
Before anything gets closed up, the new system is pressure tested and held to confirm it is sound. Testing before restoration is not optional, because finding a problem after the drywall is patched means opening it again.
Permitted work is inspected at this stage. Once the system passes, it is tied into the service, and the lines are flushed to clear debris introduced during installation. Every fixture in the house is then run and checked, including ones nobody uses.
Full water service is restored at the end of this stage. For most households, this is the day normal life resumes even though the project is not finished.
Days Four and Five: Restoration
Restoration is the stage that separates quotes that looked similar on the pipe work.
Access points are patched, taped, and floated, then textured to match the surrounding surface. Texture matching is genuinely skilled work, and a mismatched patch is visible from across the room for as long as you own the house. Paint follows once the compound has cured, which is why this stage sometimes spills past the pipe work by a day or two rather than finishing alongside it.
Confirm before signing whether drywall repair and paint are included or excluded. A quote that ends at the pipe leaves you hiring a second trade and coordinating them yourself.
What Changes the Whole-House Repipe Timeline
- Square footage and bathroom count. More fixtures means more runs and more connections.
- One story versus two. Second-floor fixtures require vertical runs through walls, which adds both time and access points.
- Attic accessibility. Low pitch, heavy insulation, or ductwork in the way slows the routing considerably.
- Foundation type. Slab homes generally route overhead, while pier and beam allows work from below.
- Ceiling texture. Matching some textures takes longer, and older homes with popcorn ceilings need to be evaluated before disturbing them.
- Permit and inspection scheduling. Frequently the least predictable element, and it varies across Houston and the surrounding municipalities.
Because those variables move the number substantially, a range from a repipe cost estimator is a starting point rather than a quote, and a firm number should follow an on-site assessment.
Living in the House During the Work
Most households stay put. A few practical expectations make it easier.
Water is off during working hours and generally restored before the crew leaves each day, so evenings function normally. Fill a few containers each morning for convenience. Expect noise during access and installation, dust despite containment, and crews moving through the house rather than staying in one room. Plan around it the way you would any renovation, and keep pets out of work areas for their safety as much as the crew’s.
What Should Be in the Scope
- Every supply line replaced, not selected runs
- The specific pipe material and brand being installed
- Fixture shutoff valves replaced as part of the work
- Permits and inspections
- Drywall repair, texture matching, and paint
- Pressure testing before restoration
- Warranty terms, duration, and whether it transfers to a future owner
- Whether the crew is in-house or subcontracted
Two quotes that differ substantially usually differ on restoration and warranty rather than on the plumbing itself.
Key Takeaways
- Pipe work typically takes three to five days, with restoration adding a day or two.
- A proper repipe opens targeted access points rather than entire walls.
- Houston slab homes are generally rerouted overhead through the attic, abandoning under-slab lines.
- Pressure testing and inspection happen before anything is closed up.
- Most households remain in the home, with water restored each evening.
- Two stories, difficult attic access, and texture matching are the main timeline variables.
- Restoration and warranty terms are where similar-looking quotes actually diverge.
Frequently Asked Questions
Do I have to move out during a repipe?
Usually not. Water is off during working hours and restored in the evenings, and most households stay in the home for the duration. Families with young children sometimes choose to be elsewhere during the noisiest days, but it is rarely necessary.
How much of my drywall gets opened?
Less than most people expect. Access points are cut where the lines actually run, which means a series of openings rather than removed wall sections. The number depends on layout and fixture locations.
Will the patches be visible afterward?
Not when texture matching is done properly and the area is repainted. Visible patches are a restoration quality problem, which is why it is worth confirming that restoration is included and who performs it.
What happens to the old pipes?
Lines that are accessible may be removed, while under-slab lines are typically abandoned in place. Leaving them is standard practice, since excavating a slab to remove abandoned pipe adds cost and risk without benefit.
Does a repipe include my water heater?
Connections at the water heater are part of the work, though replacing the unit itself is separate. If the heater is near the end of its life, doing both at once avoids opening the same connections twice.
Do I need to be home during the work?
Access is required, so arrangements need to be made, but you do not need to supervise. Agree in advance on access, working hours, and how questions during the day will be handled.
Conclusion
A whole-house repipe is a shorter and more orderly project than its reputation suggests. Access on day one, new lines on day two, testing and inspection on day three, and restoration after that covers most Houston homes. The variables worth asking about before you sign are attic access, story count, and whether drywall and paint are inside the scope or outside it.
