A whole-house repipe is one of the biggest plumbing decisions a homeowner makes - often triggered by failing polybutylene or galvanized pipe. Enter your home's square footage and pick a pipe material to see a modeled cost range, built from HomeAdvisor's and Angi's published 2026 cost data.
PEX full-repipe estimate
$5,850-$11,250
PEX is flexible, freeze-resistant, and the material most DFW plumbers now install for a full repipe, including when replacing failed polybutylene.
Modeled from HomeAdvisor's published $4.50/sq ft average repipe rate (2026 data), with a low/high spread sized the same way Angi's own national average-to-range ratio is sized.These are planning estimates only, not a quote - the number of fixtures, whether your home is slab or pier-and-beam, attic/crawlspace access, and any drywall repair all move the real number. A licensed plumber's walkthrough is the only way to get an exact price.
DFW has a large stock of homes built during the 1978-1995 window when polybutylene supply pipe was standard, plus older neighborhoods still running galvanized steel. Both materials fail with age, and unlike a single leak repair, the fix is usually a full repipe rather than a patch. Our polybutylene pipe guide covers how to identify PB pipe, the insurance implications, and the real-world DFW cost range this calculator's estimates are checked against.
Whether your home falls in that higher-risk construction window - and what your city's typical housing stock looks like - is covered in our DFW housing age by city guide.
The copper-vs-PEX multiplier above is a modeled estimate derived transparently from these sources' per-linear-foot figures and labor-share data, not a directly published total-cost figure - see the calculator's own notes for the exact derivation.
Modeled estimates from this calculator typically land between $3,000 and $20,000 depending on home size and pipe material, which lines up with the real-world DFW range of $4,000-$15,000 for a full repipe already documented in our polybutylene pipe guide - smaller or limited-scope jobs tend toward the low end, larger homes or harder attic/crawlspace access toward the high end.
PEX is what most DFW plumbers install for a repipe today - it's flexible, freeze-resistant, and runs roughly 3x-4x cheaper per linear foot in materials than copper. Copper is more traditional and has a longer track record, but the material-cost gap is the main reason most homeowners replacing failed polybutylene or galvanized pipe choose PEX instead.
