Plumbing & Repipe Cost in Texas (2026)

Plumbing repipe in Texas typically runs $4,800–$12,400 for a whole-house 2-bath PEX repipe, with PEX-A or PEX-B cross-linked polyethylene the dominant retrofit choice and the Uniform Plumbing Code (UPC) as the adopted enforcement basis. Buried service-line trench depth must clear the 12-inch design frost line. Winter Storm Uri (February 2021) collapsed Texas residential plumbing across the Plains, ERCOT-grid, and Gulf-coast climate zones simultaneously when sustained sub-freezing temperatures penetrated uninsulated attic supply lines, generating an estimated 1.7-million-plus burst-pipe insurance claims — TX SB 1281 and SB 3 mandate winterization disclosure and have driven near-universal adoption of attic-pipe insulation and freeze-protection valves on Texas single-family retrofits.

Texas water-quality & freeze drivers

  • IECC climate zone: 2A-2B-3A-3B-4B — drives freeze-protection scope on supply lines
  • Frost-line trench depth: 12-inch design minimum for buried water service
  • Water hardness profile: Very hard (10.5+ grains/gallon) — whole-house softener standard on most repipes
  • Dominant retrofit supply material: PEX-A or PEX-B cross-linked polyethylene — dominant on whole-house repipes since 2005
  • Adopted plumbing code basis: Uniform Plumbing Code (UPC) — IAPMO model adopted statewide
  • Lead service line risk tier: Moderate — partial pre-1986 service line inventory under utility review

Texas licensing & permits

  • License status: Statewide license required
  • License board: Texas State Board of Plumbing Examiners (RMP / Master / Journeyman / Tradesman) (official site)
  • Permit: city plumbing permit required; on-site sewage through TCEQ in unincorporated areas

How plumbing and repipe costs vary in Texas

State-specific code or insurance rule: The Texas State Board of Plumbing Examiners (TSBPE) is the oldest standalone state plumbing board in the United States — established in 1947 — and uniquely operates a four-tier credential system: Tradesman Plumber-Limited (TX-only entry credential), Journeyman, Master, and Responsible Master Plumber, with each company required to designate one RMP whose license number appears on every permit — a chain-of-responsibility model not used elsewhere.
