How Long Does Whole House Repiping Take

Timeline by Pipe Material

The replacement material is the single biggest factor in how long the job takes. PEX installs significantly faster than copper because of how connections are made and how the pipe is routed through the house.

PEX repiping takes 2 to 3 days for a typical single-story home with two bathrooms. PEX connections use crimp rings, expansion fittings, or push-fit connectors that take 10 to 20 seconds each. The flexible tubing can be snaked through wall cavities in long continuous runs from the manifold to each fixture without intermediate joints. A two-person crew can complete 15 to 25 fixture connections per day with PEX, which means most homes finish within two full working days, with the third day reserved for final testing and cleanup.

Copper repiping takes 3 to 5 days for the same home. Every copper connection requires cleaning the pipe end, applying flux, heating the joint with a torch, applying solder, and allowing it to cool before testing. Each joint takes 3 to 5 minutes. Copper pipe is rigid, so every change of direction requires a fitting, and every straight run must be cut to precise length. A two-person crew working with copper typically completes 8 to 15 fixture connections per day, roughly half the rate of PEX. For a detailed comparison of the two materials, see the copper vs PEX cost comparison.

Timeline by Home Size

Larger homes have more fixtures, longer pipe runs, and more wall access points, all of which add to the project duration. Here are typical timelines using PEX, which is the most common choice for residential repipes in 2026:

• Under 1,000 sq ft (1 bathroom): 1 to 2 days
• 1,000 to 1,500 sq ft (1 to 2 bathrooms): 2 to 3 days
• 1,500 to 2,500 sq ft (2 to 3 bathrooms): 2 to 4 days
• 2,500 to 3,500 sq ft (3 to 4 bathrooms): 3 to 5 days
• Over 3,500 sq ft (4+ bathrooms): 4 to 7 days

For copper, add 1 to 2 days to each of these ranges. The fixture count matters more than the raw square footage because the number of connections determines the labor hours. A 2,000 square foot home with one bathroom will repipe faster than a 1,500 square foot home with three bathrooms.

How Home Layout Affects the Timeline

Single-Story vs Two-Story

Two-story homes add 1 to 2 days compared to a single-story home of the same size. The extra time comes from routing vertical pipe runs between floors, drilling through fire blocking, and accessing second-floor wall cavities from below. Working overhead from ladders or through first-floor ceilings is slower than ground-level work. For full details on multi-story considerations, see the two-story repiping cost guide.

Slab Foundation vs Crawl Space or Basement

Homes with crawl spaces or basements allow the plumber to route most horizontal pipe runs below the floor, which is the fastest access method. The plumber works in an open space beneath the house without cutting into walls for horizontal runs, only needing wall access at the vertical points where pipes rise to fixtures.

Homes on slab foundations have no below-floor access. The existing pipes run through or under the concrete slab, and the new pipes must be rerouted through walls and the attic instead. This rerouting adds complexity and time because every pipe run that would have gone under the floor now goes up into the attic and back down through the walls to each fixture. Slab foundation repipes typically add 1 to 2 days compared to the same home with a crawl space.

Finished vs Unfinished Walls

Homes with unfinished basements, exposed studs in utility areas, or open wall cavities from an ongoing renovation are faster to repipe because the plumber has direct access to pipe routes without cutting drywall. If your home is undergoing a renovation that opens walls, the repipe timeline can overlap with the renovation work and add minimal extra days to the overall project.

What Happens Each Day of the Repipe

Understanding the daily progression helps you plan around the disruption. Here is what a typical 3-day PEX repipe of a 1,500 square foot, two-bathroom home looks like:

Day 1: Preparation and rough-in. The crew shuts off the main water supply, protects floors and furniture with drop cloths, and cuts access openings in walls and ceilings where pipe routes are needed. They begin installing the PEX manifold (if using a manifold system) and running the main supply lines from the water entry point to the manifold location. By the end of day one, the main trunk lines are in place and some fixture lines may be partially routed. Water is typically restored through a temporary connection at the end of the work day.

Day 2: Fixture connections. The crew runs individual PEX lines from the manifold to each fixture location, threading tubing through wall cavities and connecting to existing fixture shutoff valves or installing new ones. This is the highest-activity day, with the crew moving from room to room connecting each sink, toilet, shower, bathtub, dishwasher, washing machine, and outdoor hose bib. The old pipes are disconnected and capped as the new lines take over.

Day 3: Testing, inspection, and cleanup. The crew pressure-tests the entire new system to check for leaks at every connection point. If a municipal inspection is required (it usually is, since a repipe requires a plumbing permit), the inspector visits during this phase. After the test passes, the crew patches the wall access openings with temporary covers or basic drywall patches, cleans up debris, and restores full water service permanently. Detailed drywall finishing, texturing, and painting are typically handled separately by a drywall repair contractor.

How Long Is the Water Off

This is the question most homeowners care about most. The water is shut off during active work hours, typically 8:00 AM to 5:00 PM. Most plumbers restore water service at the end of each work day through either the new lines (for sections already completed) or a temporary bypass connection. You will have water each evening and overnight.

During the active work hours, no fixtures in the house will have running water. Plan for this by filling containers with water before the crew arrives each morning, using a neighbor's bathroom if needed, and scheduling laundry and dishwashing for evenings. For more practical tips, see the guide to living in your house during a repipe.

On the final day, once the pressure test passes and the inspection (if required) is complete, water service is fully restored through the new system. From that point forward, every fixture in the house runs on the new pipes.

What Can Delay a Repipe

Several factors can push the timeline beyond the initial estimate:

• Unexpected pipe routing obstacles. Hidden structural elements, HVAC ducts, or electrical wiring in wall cavities can force the plumber to reroute pipes, adding time for additional wall openings and longer pipe runs.
• Permit and inspection scheduling. In busy jurisdictions, the plumbing inspector may not be available on the day the crew finishes. This does not extend the work itself, but it can delay the final signoff and the switch to permanent water service.
• Old pipe removal complications. Galvanized steel pipes that are heavily corroded may be difficult to remove from wall cavities, especially at threaded fittings that have fused together from decades of corrosion. This adds removal time that is not always predictable in advance.
• Asbestos-containing materials. Homes built before 1980 may have asbestos insulation on pipes or in surrounding wall materials. If asbestos is discovered, work must stop until a certified abatement contractor handles the removal, which can delay the repipe by several days to a week.
• Scope changes during the project. Once walls are open, the plumber or homeowner may discover additional problems (a corroded water main, a failing shutoff valve, a water heater connection that needs updating) that add work to the original scope.

Does Drywall Repair Add to the Timeline

The repipe itself and the drywall repair are usually separate projects with separate timelines. The plumbing crew finishes their work, and then a drywall contractor comes in afterward to patch, tape, texture, and paint the wall openings. Drywall repair adds 1 to 3 days of work depending on the number of openings, but it can be scheduled at your convenience after the repipe is complete. There is no requirement to do it immediately. Many homeowners wait a few weeks to confirm no leaks before closing up the walls. The drywall repair cost guide covers what to budget for this phase.
