Whole House Repipe Fremont

Whole House PEX Repipe: Fremont, CA

This whole house repiping project in Fremont replaced deteriorating polybutylene pipes in a 2,200 sq ft two-story home in the Mission San Jose neighborhood. Polybutylene piping, common in homes built between 1978 and 1995, is known to fail without warning, and this home had already experienced two slab leaks within 18 months.

The Problem

The homeowners contacted us after their second slab leak in under two years. Their insurance company was threatening non-renewal due to the repeated claims. A whole-home inspection confirmed that the original polybutylene supply lines were brittle throughout, with multiple sections showing stress fractures. It was no longer a question of if the pipes would fail: it was a matter of when.

Our Solution

We recommended a complete Uponor PEX-A repipe in Fremont, the fastest, most cost-effective solution for two-story homes with polybutylene. PEX’s flexibility means fewer fittings, less wall disruption, and faster installation per floor. Our crew completed the full repipe in two days, patched and textured all drywall access points, and restored water both evenings before leaving.

The project was permitted through the City of Fremont and passed city inspection on the first visit. See our guide to what to expect from Fremont’s repipe permit and inspection process for more detail on how that works. We also provided full documentation for the homeowners’ insurance carrier confirming the polybutylene had been completely removed and replaced.

Results

No leaks, full pressure, and the homeowners’ insurance was renewed without issue. The Uponor PEX-A system carries a 25-year manufacturer warranty backed by our 30-year labor warranty, one of the strongest warranty packages available for a whole house repipe in the Bay Area.
