What to Expect During a Whole House Repipe

Wondering what to expect during a repipe of your whole house? Most homeowners picture weeks of chaos, torn-apart walls, and no running water. The reality is far less dramatic: a professional crew typically finishes a residential repipe in 2 to 5 days, restores your water every evening, and cuts far fewer holes than you would guess. This day-by-day walkthrough covers the timeline, the noise, the water shutoffs, and exactly how to prepare your home so the project runs smoothly.

How Long a Repipe Takes

Timeline depends on home size, number of bathrooms, pipe material, and how many stories the crew must navigate. These are realistic 2026 ranges from working repipe companies.

• 1-bath home or condo: 1 to 2 days
• 2-bath single-story home: 2 to 3 days
• 3-4 bath two-story home: 3 to 5 days
• Large or complex homes: 5 to 7 days

PEX repipes run faster than copper because the flexible tubing pulls through framing with fewer joints and fittings. Two-story homes take longer because the crew must route pipes between floors. Homes on slabs add time if lines must be rerouted through attics instead of under the foundation. Your contractor's written schedule should break the job into these phases so you know what happens each day.

Before the Crew Arrives: Prep Checklist

A little preparation saves hours of disruption. Do this the evening before day one.

• Clear work areas. Move furniture, boxes, and belongings at least 3 feet away from walls in bathrooms, kitchens, laundry rooms, and anywhere pipes run. Empty under-sink cabinets completely.
• Clear attic and crawl space access. The crew needs to get into attics, crawl spaces, and utility closets. Move stored items away from access hatches.
• Protect valuables. Cover furniture near work zones with sheets. Vibrations from cutting and drilling can knock pictures off walls, so take down anything fragile or valuable near bathrooms and kitchens.
• Plan water needs. Fill a few jugs and the bathtub with water for toilet flushing during daytime shutoffs. Stock paper plates to cut down on dishwashing.
• Arrange pets and kids. Doors will be propped open and strangers will be moving through the house. Board pets or keep them in a closed room away from work areas.
• Confirm the details. Verify start time, pipe material and brand, permit status, and whether drywall patching is included or handled separately.

Day 1: Shutdown, Demo, and New Runs

Day one starts early. The crew shuts off the main water supply, drains the existing lines, and lays down floor protection along their work paths. Then the cutting begins: small access holes in drywall at strategic points where new pipes need to pass through walls and ceilings. Expect rectangular openings roughly 1 to 2 feet square, not entire missing walls.

Next, the crew starts running the new pipe. With PEX, they feed flexible tubing through the framing, up walls, and across attics, connecting runs with fittings as they go. With copper, they cut, clean, and solder rigid sections in place, which is slower and noisier. Old pipes are usually abandoned in the walls rather than removed, which avoids massive demolition.

By end of day one on a typical 2-bath home, the main runs are usually in place and the crew restores water service for the evening, sometimes through temporary connections. You will have water overnight in most cases.

Days 2-3: Rough-In and Connections

The middle days are about connections. The crew ties the new lines into each fixture: sinks, toilets, showers, tubs, washing machine, dishwasher, water heater, and outdoor hose bibs. Each fixture gets new shutoff valves, which is a welcome upgrade if your old valves were frozen or corroded.

This is also when the water heater gets reconnected or replaced. If you planned a water heater swap with the repipe, it happens now while the plumber and the open walls are already there, saving you a separate service call later.

Expect the most noise during these days: reciprocating saws, drills, and soldering torches if the job is copper. The crew works room by room, so you can usually retreat to a finished part of the house. Water goes off during working hours and comes back on each evening.

Day 4-5: Inspection and Water Restoration

Before any drywall gets patched, the new system must pass inspection. The crew pressurizes the lines, typically with air at around 100 psi or at full water pressure, and the system must hold that pressure with zero loss for the required test period. The city or county inspector then checks the rough-in: proper pipe supports, nail plates protecting pipes through studs, correct fittings, and code-required shutoffs.

This step is exactly why repipe permits and inspections matter. The inspector is your independent quality check, and nothing gets buried behind drywall until it passes. If anything fails, the crew fixes it and calls for re-inspection, which can add a day.

Once the rough-in passes, the system is fully charged with water and every fixture is tested: faucets run, toilets flush, showers get checked for hot and cold, and the crew walks the house listening and looking for any drip. Only after a clean test does patching begin.

After the Crew Leaves: Patching and Paint

Drywall patching is the phase homeowners ask about most, and it is usually less painful than feared. A good repipe crew cuts clean, minimal openings, often 10 to 30 holes in a whole house, each small enough to patch in minutes.

Patching itself may happen the same week or a few days after the plumbing work, depending on whether your contractor handles it in-house or uses a drywall subcontractor. The patches get taped, mudded, sanded, and textured to match the surrounding wall. Texture matching is the trickiest part on older homes with heavy orange-peel or knockdown finishes, so ask your contractor how they handle it.

Paint is typically the homeowner's responsibility unless your contract says otherwise. Even with good texture matching, fresh patches usually need paint to disappear completely. Budget a weekend or a painter's visit to finish the job. Confirm in writing before work starts whether patching and paint are included in your quote, because this is the most common source of repipe billing disputes.

Living Through It: Water, Noise, and Pets

Water. Plan on no running water from roughly 8 a.m. to 5 p.m. on work days. Evenings and mornings are normally fine. Keep drinking water on hand and fill the tub for toilet flushing. If anyone in the household has medical needs requiring constant water access, discuss the schedule with the contractor in advance.

Noise and dust. Expect sawing, drilling, and banging during the day. Dust is moderate since the crew is cutting drywall, not demolishing rooms, but it travels. Close bedroom doors, cover electronics, and run your HVAC fan with a fresh filter after the job to clear airborne dust.

Pets. The combination of strangers, noise, open doors, and open wall cavities is stressful and unsafe for pets. The best plan is daycare or a friend's house during work hours. At minimum, confine pets to a finished room far from the work zone with the door closed.

Security. Crews come and go, and doors stay propped for equipment. If that bothers you, ask the foreman to keep a door attendant system or install a temporary lockbox arrangement. Reputable companies are used to the question.

A repipe is one of the highest-value upgrades you can make to an older home, and the disruption is measured in days, not weeks. For material choices that affect the timeline, see our guide to the best pipe for a whole house repipe, and browse the full repiping hub for cost and planning resources.
