When Your Home Needs Repiping

Pipe Types That Need Replacement

  • Galvanized Steel: Common in homes built before 1960. Corrodes from the inside, causing rust-colored water and restricted flow.
  • Polybutylene: Used from 1978 to 1995. Known to crack and fail without warning. Most insurance companies will not cover homes with polybutylene pipes.
  • CPVC: Becomes brittle over time, especially in hot water lines. Prone to cracking at joints.
  • Copper (40+ years): Develops pinhole leaks from corrosion, especially with San Antonio's hard water.

Repiping as Part of a Larger Project

Repiping is often most cost-effective when combined with other work. If you are planning a home remodel, the walls are already open — making it the ideal time to replace old pipes. Homes with frequent slab leaks often benefit from a full repipe that reroutes supply lines through the attic or walls, eliminating the under-slab pipes entirely. After repiping, installing a water softener protects your new pipes from San Antonio's hard water.

Repiping Cost in San Antonio

ServiceTypical Range
PEX Repipe — Average Home (6–12 fixtures)$4,000 – $8,000
PEX Repipe — Larger Home (13+ fixtures)$6,500 – $15,000
Copper Repipe — Average Home$8,000 – $15,000
Galvanized or Polybutylene Replacement$4,500 – $8,000

Most San Antonio homes are repiped with PEX, which resists hard water and clay soil movement better than copper. Water restored by end of day. Most projects 1–2 days. Permit and inspection included. Financing available.

Frequently Asked Questions

Whole-house repiping in San Antonio typically costs $4,000 to $15,000 depending on the size of the home, number of fixtures, pipe material (PEX vs copper), and accessibility of existing pipes. A 1,500 square foot home with standard access usually falls in the $5,000 to $8,000 range. C.S.W. Power Solutions provides a detailed, itemized estimate before any work begins.
Signs your home needs repiping include frequent leaks in different locations, discolored or rusty water, low water pressure throughout the house, visible corrosion on exposed pipes, pinhole leaks, water that tastes or smells metallic, and pipes that are older than 40 years (galvanized steel) or 50 years (copper). If your San Antonio home was built before 1980, the pipes should be inspected.
Most whole-house repiping projects take 2 to 5 days depending on the size of the home and complexity of the plumbing system. A typical 3-bedroom home is completed in 2 to 3 days. Water is usually off for only portions of each day, and we coordinate to minimize disruption. C.S.W. Power Solutions handles all permitting, inspection, and drywall patching as part of the project.
Both PEX and copper are excellent choices. PEX is more affordable, faster to install, resistant to corrosion and scale buildup, and flexible enough to reduce the number of joints. Copper is more durable long-term, has a proven track record, and adds value to the home. For most San Antonio homes, we recommend PEX for its cost-effectiveness and resistance to the area's hard water. C.S.W. Power Solutions installs both materials and can advise based on your specific situation.
You do not need to move out during repiping. Water is turned off during active work hours but is restored each evening. There will be some noise from cutting drywall and running new pipe, and some areas of the home will have temporary openings in walls. Most homeowners stay in the home during the project without significant inconvenience.
Yes. Whole-house repiping requires a plumbing permit from the San Antonio Development Services Department. The work must be performed by a licensed plumber and pass city inspection. C.S.W. Power Solutions (License RMP46592) handles all permitting and scheduling of inspections as part of every repiping project.
