How Long Does It Take to Repipe a House?
Homeowners facing recurring pinhole leaks, rusty tap water, or failing galvanized pipes urgently ask how long it takes to repipe a house. For an average single-family home measuring 1,500 to 2,500 square feet with two bathrooms, professional whole-house repiping typically takes two to four days of plumbing labor. However, factoring in city plumbing inspections, drywall patching, texturing, and painting means the entire restoration spans one to two weeks.
Material Selections: Flexible PEX versus Rigid Copper
The primary factor dictating repiping duration is the piping material selected. Modern residential repiping predominantly utilizes flexible cross-linked polyethylene (PEX) tubing. PEX can be threaded through wall cavities and floor joists like electrical wiring, dramatically reducing the number of drywall cutouts required. An experienced plumbing crew can complete a whole-home PEX repipe in two to three days.
In contrast, repiping an entire home with rigid copper piping requires substantially more labor and structural access. Plumbers must cut continuous trenches across drywall, meticulously measure rigid pipe lengths, and sweat hundreds of copper elbow fittings using open-flame torches. Copper repiping generally requires three to five days of intensive plumbing labor and results in significantly more drywall damage throughout the home.
Compare whole-home repiping timelines and characteristics across piping materials:
| Piping Material System | Plumbing Installation Time | Drywall Access Cutouts | Expected Service Lifespan |
|---|---|---|---|
| PEX-A / PEX-B Tubing | 2 to 3 Working Days | Minimal (Small access holes) | 40 to 50+ Years (Scale resistant) |
| Type L Rigid Copper | 3 to 5 Working Days | Extensive (Large wall openings) | 50+ Years (Subject to acidic pinholes) |
| CPVC Plastic Piping | 3 to 4 Working Days | Moderate (Glued rigid fittings) | 20 to 25 Years (Becomes brittle) |
| Commercial Multi-Story PEX | 5 to 8 Working Days | Significant shaft penetrations | 50+ Years (Heavy manifold layout) |
Water Availability and Daily Plumbing Crew Workflow
A common concern for families during a whole-home repipe is whether they must vacate the residence. Professional repiping companies structure their workflow so occupants rarely need to relocate to a hotel. Plumbers begin by running the new trunk and branch lines alongside the existing plumbing system while keeping the old pipes pressurized and fully functional.
The household water main is typically shut off only during daytime working hours—usually between 8:30 AM and 4:30 PM. At the end of each workday, plumbers activate temporary water tie-ins or complete zonal transitions so the family has running cold and hot water overnight. The definitive transition from the old plumbing lines to the new PEX system takes only four to six hours on the final plumbing day.
Review the phased operational sequence executed during a professional 4-day residential repipe:
| Day of Repiping | Operational Plumbing Focus | Household Water Status | Key Milestone Achieved |
|---|---|---|---|
| Day 1 (Full Day) | Covering floors & cutting drywall access holes | Water on all morning; brief off mid-day | Access holes cut; main PEX trunk line run |
| Day 2 (Full Day) | Routing branch lines to fixtures & manifolds | Water off 9am-4pm; restored by 5pm | All bathroom & kitchen fixtures stubbed out |
| Day 3 (Full Day) | Final tie-in, valve hookups, pressure test | Water off 9am-3pm; full service restored | System pressurized; city inspection requested |
| Day 4 & 5 (Subsequent) | City plumbing inspection & drywall patching | Water fully operational | Inspected, insulation replaced, drywall patched |
Municipal Inspections, Pressure Testing, and Drywall Restoration
Once all new piping runs, shutoff valves, and fixture supply lines are installed, the plumbing system must undergo an official air pressure decay test before walls can be closed. Plumbers cap all lines, pump the system with fifty to one hundred PSI of compressed air, and leave gauges attached for municipal building inspectors to verify that zero pressure drops occur over twenty-four hours.
Following inspector sign-off, the restoration phase commences. Specialized drywall contractors install backing blocks, screw sheetrock patches into all access holes, tape seams, apply two to three coats of joint compound, and match existing wall textures (such as orange peel or knockdown). After compound cures and dries, painters apply primer and finish paint, returning the living space to immaculate condition within three to five days.
How to Prepare for a Whole-House Repipe in 5 Steps
Follow these five practical homeowner preparation steps to facilitate a smooth, efficient residential repiping project.
Clear Under-Sink Cabinets Completely
Empty all cleaning supplies, toiletries, and storage items from beneath bathroom vanities and kitchen sinks to give plumbers clear access.
Move Furniture Away from Plumbing Walls
Pull beds, dressers, and sofas at least three to four feet away from walls containing plumbing pipes and fixture valves.
Store Bottled Water for Daytime Hours
Fill pitchers and keep bottled water on hand for drinking, cooking, and flushing toilets during daytime water shut-off windows.
Secure Household Pets During Work Hours
Keep pets secured in an unaffected bedroom or off-site to protect them from loud tool noise, dust, and open exterior doors.
Coordinate Municipal Inspection Times
Ensure someone is home to grant the municipal plumbing inspector access to inspect pressure gauges before drywall repair begins.
Frequently Asked Questions (8 Questions Answered)
Q1: Can you live in the house while it is being repiped?
Yes, professional repiping crews ensure water service is restored every evening, allowing families to comfortably remain in their home overnight.
Q2: How long is water turned off during a house repipe?
Water is typically shut off during active work hours from approximately 9:00 AM to 4:30 PM, and turned back on each evening.
Q3: Is PEX repiping faster than copper repiping?
Yes, PEX is flexible and can be snaked through wall studs with minimal drywall cutting, cutting installation time by nearly half compared to rigid copper.
Q4: Does repiping a house include replacing outdoor sewer lines?
No, repiping refers exclusively to clean pressurized freshwater supply lines; sewer line replacement is a separate drainage service.
Q5: How much does it cost to repipe a 2,000 square foot house?
Whole-home repiping typically ranges from four thousand to ten thousand dollars for PEX, and eight thousand to fifteen thousand dollars for copper.
Q6: How many drywall holes are made during repiping?
A typical 2-bath home requires twenty to forty small drywall access cutouts, which are patched, textured, and painted upon completion.
Q7: How long do new PEX water pipes last?
High-quality PEX-A and PEX-B plumbing systems have an expected lifespan of forty to fifty years or more, resisting corrosion and scale.
Q8: Does homeowners insurance cover whole-house repiping?
Insurance covers water damage resulting from sudden pipe bursts, but age-related whole-house pipe replacement is considered maintenance.
