Whole-House Repipe in Rancho Peñasquitos, CA

Copper has a proven 50+ year track record and is highly durable, but costs 30-40% more than PEX and is susceptible to pinhole leaks from San Diego's hard water over time. PEX is flexible, resistant to mineral scale, handles freeze conditions better, and is significantly less expensive. Both carry 25-year or lifetime warranties depending on the brand. We recommend PEX for most San Diego homes due to its hard water resistance and cost advantage.

A whole-house repipe in San Diego typically costs $4,000-$10,000 depending on the size of the home, number of fixtures, pipe routing complexity, and whether you choose PEX or copper. A 1,500 square foot home with two bathrooms runs $4,000-$6,000 with PEX. Larger homes with more complex layouts are at the higher end of the range.

Most Rancho Peñasquitos homes were built between the late 1980s and early 2000s on slab foundations with copper supply lines run beneath the slab. After 25-35 years, those copper lines develop pinhole leaks from gradual corrosion, soil contact, and pressure cycling. The leaks often go undetected for months because they're under the slab, the first sign is usually a warm spot on the floor, an unexplained jump in your water bill, or moisture appearing at a wall edge. We use acoustic and thermal imaging equipment to pinpoint the exact location before any concrete is opened.

Probably yes. Water hardness along the I-15 corridor through PQ runs significantly higher than coastal San Diego, and the buildup damages water heaters, dishwashers, fixtures, and shower valves over time. A whole-house softener typically pays for itself within five to seven years through reduced fixture replacement, extended water heater life, and lower soap and detergent use. We install salt-based and salt-free softener systems and can quote a proper sizing based on your household's actual water consumption.
