Whole-house repipes are the kind of plumbing project nobody plans for. Most Antelope Valley homeowners learn the term after their second slab leak in three years, when the plumber finally says the magic words: it is time to repipe. The decision is real, the cost is significant, and getting the right answer the first time saves you tens of thousands of dollars over the life of the house.
What makes a repipe necessary
Three signs that should put repipe on the table: multiple leaks on the same vintage of pipe within a short window (two slab leaks within five years), visible corrosion or pinhole leaks on accessible copper, or persistent low water pressure that pressure-boosting cannot fix. Antelope Valley homes built between 1960 and 1990 frequently have original copper supply lines now reaching end of life.
Galvanized steel is overdue
If you have galvanized steel supply lines (anything pre-1960), repipe was already overdue. Galvanized rusts from the inside, restricts flow, and contaminates water. The EPA drinking water guidance notes that corroding metallic pipes are a recognized source of contamination — iron, lead, and other metals leach into water.
Copper vs PEX
The two real choices for a modern repipe: Type L copper or PEX-A tubing. Copper is proven and code-compliant. Downside: about 50% more than PEX, and Antelope Valley soils plus hard water are aggressive enough that copper installed today faces the same corrosion risk over a 40-year horizon. PEX-A is flexible, faster to install, less expensive, and immune to most corrosion modes. Most reputable plumbers recommend PEX-A for whole-house repipes today.
What the work involves
A whole-house repipe runs new supply lines from the meter to every fixture. Stages: planning (1 week), permits (1-2 weeks), demo and access cuts (1-2 days), new pipe installation (2-4 days), pressure testing and inspection (1 day), drywall patching (2-3 days), paint (1 day). Most repipes complete in 5-7 working days inside the house. You can usually stay during the work.
Cost ranges
For a 2,000 square foot single-story slab-on-grade Antelope Valley home, expect $8,000-15,000 for a PEX repipe with drywall patching. Two-story homes run 30-50% more. Custom or large homes can run $25,000-40,000+.
Bundling with other plumbing work
A whole-house repipe addresses supply-side issues. It does not fix drain or sewer problems, which are separate scope. For related needs, we recommend comprehensive residential and commercial plumbing services in the DFW region.
Permits and inspections
Whole-house repipes require permits in every Antelope Valley jurisdiction. Two inspections: rough-in (after pipe is run, before drywall closes) and final (after fixtures are reconnected and pressure tested). Permits add $300-800 depending on jurisdiction and house size. Skipping permits jeopardizes resale and homeowner insurance.
