Repiping a house is one of the larger projects a homeowner authorizes, and most of the anxiety around it comes from not knowing what the sequence looks like. People imagine open walls for weeks and a house they cannot live in. The reality is a defined series of stages, most of which are shorter than expected, with the decisions that matter concentrated at the beginning rather than the middle. Knowing what happens at each stage also tells you what to confirm before signing, which is where the difference between two whole house repiping quotes usually lives.
Short Answer
Seven stages: the estimate and walkthrough, scope and contract, preparation, access and installation, pressure testing and inspection, restoration, and final walkthrough. The pipe work itself is typically a matter of days. The decisions that determine how well it goes are made in the first two stages, particularly whether drywall repair, texture matching, and paint are inside the scope and what the warranty actually covers.
Stage 1: The Estimate and Walkthrough
A proper estimate starts with someone in your home rather than a number over the phone.
What they are assessing: the number of fixtures and bathrooms, whether the home is one story or two, the foundation type, attic access and clearance, where the water heater sits, what the existing pipe material is, and how accessible the runs are. Each of those changes the scope, which is why quotes produced without a visit are estimates of a house the estimator has not seen.
If the failing system has not been positively identified, diagnostics belong here too. Supply-side and drain-side problems present similarly to a homeowner and call for completely different work, and hydrostatic testing settles that before anyone commits to a scope.
Ask what the quote includes and, more usefully, what it excludes. That single question surfaces most of the difference between competing proposals.
Stage 2: Scope, Contract, and Permit
This is the stage that determines everything downstream, and it is the one homeowners move through fastest.
Confirm in writing: the pipe material and brand being installed, whether every supply line is being replaced or only selected runs, whether fixture shutoff valves are included, who pulls the permit, whether drywall repair and texture matching and paint are in scope, the warranty terms and duration and whether it transfers to a future owner, whether the crew is in-house or subcontracted, and the payment schedule tied to milestones.
Two quotes that look similar frequently differ on restoration and warranty rather than on the plumbing. A proposal ending at the pipe means hiring a second trade and coordinating them yourself.
Permitting happens here as well, and inspection is part of the process rather than an optional extra.
Stage 3: Preparation
Your part is straightforward and worth doing properly, because it speeds everything after it.
Clear the areas under sinks and inside the water heater closet, empty closets backing onto plumbing walls, make sure attic access is reachable, take down wall hangings in work areas, move valuables, and plan for pets to be somewhere quiet. Agree access and working hours in advance.
The crew’s part is floor protection along traffic paths, plastic sheeting for dust containment, and a plan for when water will be off each day.
Stage 4: Access and Installation
The stage that looks most alarming and is the most routine.
Existing lines are located and marked so access points are cut where pipe actually runs. A competent repipe opens a series of targeted openings rather than removing whole wall surfaces, which surprises people who expected the house to be gutted.
New supply lines are then run to every fixture. On a slab home the routing generally goes overhead through the attic rather than under the foundation, which is why repeated slab leak repair eventually gives way to a repipe. Rather than tunneling under the slab again, the under-slab lines are abandoned in place and the house is fed from above, removing the failure point instead of patching it.
Valves are replaced as part of the work, which cheaper quotes sometimes omit and which matters the first time you need to isolate a fixture.
Stage 5: Pressure Testing and Inspection
Nothing gets closed up until the new system has been tested and held.
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 point, and 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.
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.
Stage 6: Restoration
The stage that separates proposals that looked identical.
Access points are patched, taped, and floated, then textured to match the surrounding surface. Texture matching is genuinely skilled work, and a mismatched patch stays visible for as long as you own the house. Paint follows once the compound has cured, which is why this stage sometimes runs a day or two past the pipe work rather than finishing alongside it.
If restoration was excluded from the scope, this is where you find out what that means in practice.
Stage 7: Final Walkthrough and Warranty
The stage most often skipped, and worth insisting on.
Walk the house with the contractor. Run every fixture, check hot and cold at each, look at every patched area, and confirm water pressure at the furthest fixture from the heater. Note anything unresolved as a punch list rather than mentioning it later by text.
Collect the documentation: the permit and inspection record, warranty paperwork and how to make a claim, the material and brand installed, and any as-built information about routing. Store it with your house records, because a future buyer’s inspector will ask and a transferable warranty is worth something at resale.
For the first few weeks, watch for damp spots around patched areas and any change in pressure. Problems are rare after a passed pressure test, and they are far easier to address while the relationship is fresh.
How Long Repiping a House Takes
Pipe work on a typical home is generally a matter of days rather than weeks, with restoration adding a day or two after that. Most households stay in the home throughout, with water off during working hours and restored each evening.
What extends it: square footage and bathroom count, a second story, difficult attic access, real property that needs a separate proceeding, ceiling textures that take longer to match, and permit or inspection scheduling, which is frequently the least predictable element.
Key Takeaways
- The decisions that matter are concentrated in the estimate and contract stages, not during the work.
- An estimate should follow a walkthrough, since scope depends on layout, access, and foundation type.
- Confirm in writing whether drywall repair, texture matching, and paint are included.
- A repipe opens targeted access points rather than removing whole walls.
- Slab homes are generally rerouted overhead, abandoning the under-slab lines.
- Pressure testing and inspection happen before anything is closed up.
- Texture matching is skilled work, and a poor patch is visible permanently.
- Insist on a final walkthrough and collect the permit, warranty, and material documentation.
Frequently Asked Questions
How long does repiping a house take?
Pipe work is usually a matter of days, with restoration adding a day or two. Two-story homes, difficult attic access, and permit scheduling are what extend it.
Do I need to move out?
Usually not. Water is off during working hours and restored in the evenings, and most households stay in the home for the duration.
How much drywall gets opened?
Less than most people expect. Access points are cut where the lines run, producing a series of openings rather than removed wall sections. The number depends on layout and fixture locations.
What should I confirm before signing?
Pipe material and brand, whether all supply lines are included, whether valves are replaced, permit responsibility, whether restoration and paint are in scope, warranty terms and transferability, and whether the crew is in-house.
What happens to the old pipes?
Accessible lines may be removed, while under-slab lines are typically abandoned in place. Excavating a slab to remove abandoned pipe adds cost and risk without benefit.
Is a transferable warranty worth anything?
Yes, at resale. A warranty that follows the home gives a buyer confidence about the plumbing, and it is documentation their inspector will note.
Conclusion
Repiping a house follows a predictable sequence, and the parts homeowners worry about most are the shortest. Access and installation look dramatic and pass quickly. Testing and inspection happen before anything is concealed. What determines whether the project goes well is settled long before the first wall is opened, in the estimate and the scope, which is why the most useful question you can ask a contractor is what their quote does not include.
