House Repiping Cost Calculator [2026]
Estimate 2026 costs for full-home water line replacement (PEX vs. Copper).
House Repiping FAQs (2026)
Common 2026 indicators include **persistent low water pressure**, discolored (rusty) water, a metallic taste, or frequent pinhole leaks. If your home was built before 1990 and still has galvanized steel or polybutylene pipes, a full repipe is highly recommended to avoid catastrophic water damage.
PEX (Cross-linked Polyethylene) is roughly **40% cheaper** to install because it is flexible and requires fewer joints. In 2026, PEX-a is the standard because it can expand significantly during freezes without bursting, whereas copper is rigid and prone to cracking in cold snaps.
A standard 3-bedroom, 2-bathroom home usually takes 3 to 5 days. The water is typically only shut off during work hours (8 AM – 5 PM) and restored each evening. Drywall patching and painting usually add another 2–3 days to the total timeline.
Yes. A “whole-house repipe” is a major selling point in 2026 real estate listings. It provides buyers peace of mind regarding water quality and insurance eligibility, often yielding a **60-80% Return on Investment (ROI)**.
If your pipes run underneath a concrete slab foundation, a leak requires expensive jackhammering or “rerouting” pipes through the attic/walls. Rerouting is the preferred 2026 solution as it prevents future slab issues and is often cheaper than repairing the concrete.
