PEX Repipe Cost in 2026: Price Per Square Foot
PEX repipe cost is the number every homeowner with aging pipes wants first: in 2026, a whole-house PEX repipe typically runs $1.50 to $4.00 per square foot, or roughly $4,500 to $15,000 for most single-family homes. PEX (cross-linked polyethylene) has become the default repipe material in America because it costs 40-60% less than copper while installing faster and resisting the freeze bursts and pinhole leaks that kill older pipe. This guide breaks down exactly what drives the price, how PEX compares to copper dollar-for-dollar, and how to read a repipe bid without getting burned.
What a PEX Repipe Includes
A "repipe" means replacing all the hot and cold water supply lines in your home — not the drains. A complete PEX repipe bid should include:
- All new PEX tubing (usually PEX-A with expansion fittings, the premium method) run to every fixture
- New shutoff valves at each fixture and a new main shutoff
- New supply lines to water heater, washing machine, ice maker, and hose bibs
- Permits and inspections
- Drywall/ceiling patching to "paint-ready" (or at least "texture-ready" — confirm which)
What is usually not included: the water heater itself, fixture replacement, full repainting, and drain line work. Get these exclusions in writing. For the broader repiping picture, see our repiping hub and the full cost to repipe a house guide.
PEX Repipe Cost Per Square Foot
Per-square-foot pricing is how most repipe specialists estimate jobs. In 2026:
| Home type | Typical range per sq ft |
|---|---|
| Single-story, crawlspace or basement | $1.50 - $2.50 |
| Single-story, slab foundation | $2.00 - $3.50 |
| Two-story, any foundation | $2.50 - $4.00 |
| Home with many bathrooms (4+) | Add $0.50 - $1.00 per sq ft |
Why the spread? Access is everything. A single-story ranch with a crawlspace lets plumbers run PEX quickly through open framing. A two-story on a slab means fishing lines through finished walls and ceilings — more labor, more patching. Slab homes often route new PEX through the attic instead of breaking concrete, which adds material but saves the slab.
Cost by Home Size and Bedrooms
Square footage alone doesn't set the price — fixture count does — but these 2026 ranges are realistic for standard 2-bath homes:
| Home size | Typical PEX repipe cost |
|---|---|
| 1,000 sq ft (2 bed / 1-2 bath) | $4,500 - $7,500 |
| 1,500 sq ft (3 bed / 2 bath) | $6,000 - $10,000 |
| 2,000 sq ft (3-4 bed / 2-3 bath) | $8,000 - $13,000 |
| 2,500+ sq ft (4+ bed / 3+ bath) | $10,000 - $15,000+ |
Each additional full bathroom typically adds $800-$1,500 because of the extra fixture runs, valves, and wall access needed.
PEX vs Copper Repipe Cost
This is the comparison every homeowner asks about:
| Factor | PEX repipe | Copper repipe |
|---|---|---|
| Typical whole-house cost | $4,500 - $15,000 | $8,000 - $25,000+ |
| Material cost | ~$0.50-$1.50/ft of tubing | ~$3-$8/ft of pipe |
| Install time (typical home) | 2-4 days | 4-8 days |
| Freeze resistance | Expands; resists bursting | Bursts when frozen |
| Corrosion / pinhole leaks | Immune | Susceptible in aggressive water |
| Expected lifespan | 40-50+ years | 50-70+ years |
| Water taste | Neutral once flushed | Neutral |
Copper still wins on proven lifespan and fire resistance, and some homeowners prefer it for resale perception. But for most homes, PEX delivers 90% of the benefit at roughly half the price — and its freeze resistance alone prevents the burst-pipe disasters copper suffers every winter. Our PEX vs copper repipe cost guide goes deeper on the tradeoffs.
What Drives the Price Up or Down
- Foundation type. Crawlspace/basement = cheapest access. Slab = most expensive (attic reroutes or concrete cutting).
- Number of stories. Two-story homes cost 25-40% more than single-story at the same square footage.
- Fixture count. More bathrooms, wet bars, and laundry rooms mean more runs and more wall openings.
- Wall finishes. Plaster and tile cost more to open and patch than drywall.
- Local labor rates. Coastal metros run 30-50% above national averages; rural areas run below.
- Permit fees. Typically $100-$500 depending on jurisdiction — a legitimate line item, not padding.
- Drywall repair scope. "Patch to texture" vs "paint-ready" vs "you handle the drywall" can swing the bid by $1,000-$2,500. Clarify before signing.
- Water quality. Aggressive or acidic well water may call for additional treatment or push the recommendation toward PEX-A specifically, since PEX is immune to the pinhole corrosion that plagues copper in low-pH water.
- Code upgrades. Many jurisdictions now require pressure regulators, expansion tanks, or seismic straps on the water heater when the system is opened up — legitimate add-ons that typically add $200-$600 total.
One more pricing note: some companies quote suspiciously low, then discover "unforeseen issues" mid-job. A reputable repipe specialist does a thorough walkthrough — attic, crawlspace, water heater area — before quoting, and puts the drywall scope in writing. If a bid is 30% below the others with no explanation, something is missing from it.
How Long Does a PEX Repipe Take?
For a typical 1,500-2,000 sq ft home: 2-4 days for the plumbing work, plus 1-3 days for drywall patching and texture. You usually keep water service each evening — crews cap lines and restore water at day's end. Whole timeline from signed contract to painted walls: about 1-2 weeks. Copper repipes take roughly twice as long because every joint is soldered individually while PEX connections take seconds.
Reading a Repipe Quote
Compare bids line by line, not just the bottom number. A trustworthy quote specifies: PEX type (A is best, B is fine, avoid bargain-bin brands), fitting system (expansion vs crimp), number of fixtures covered, drywall repair scope, permit responsibility, warranty length (10+ years on labor is standard from repipe specialists), and a firm start/completion window. Red flags: a quote given without opening any walls or checking the attic, "today only" pricing, or no license number on the paperwork. Verify the license with your state board before paying a deposit. Also ask whether the warranty covers both materials and labor — manufacturer warranties cover the pipe, but only the installer's labor warranty protects you if a fitting fails in year three.
PEX-A vs PEX-B: Does the Type Matter?
Not all PEX is equal, and your quote should name the type. PEX-A (made with peroxide cross-linking, e.g. Uponor/Wirsbo) is the most flexible and uses expansion fittings — the fitting actually gets stronger as the pipe contracts around it, and the pipe can be repaired with heat if kinked. It's the premium choice and what most repipe specialists install. PEX-B (silane cross-linking) is stiffer, uses crimp or clamp fittings, and costs less — perfectly serviceable, and the most common type in big-box stores. PEX-C (electron-beam) is the least common in the US. For a whole-house repipe you're living with for decades, PEX-A with expansion fittings is worth the modest premium (typically 10-20% more than PEX-B on the total job). Whatever type you choose, insist on fittings from the same manufacturer as the pipe — mixing brands voids most warranties.
Is a PEX Repipe Worth It?
If your home has galvanized steel supply lines (common pre-1960), polybutylene (1978-1995), or copper with recurring pinhole leaks, a repipe isn't optional — it's a matter of when, not if. Galvanized pipes strangle water pressure and rust from the inside; polybutylene can fail catastrophically. A PEX repipe typically pays for itself in avoided leak damage, and it removes the single biggest plumbing red flag on a home inspection. Need a quote? Call (877) 762-1902.
