Backed by 5-Star Reviews and trusted across San Diego, we’re the team to call when it’s time to repipe with confidence.
With over 40 years of experience, we replace old under-slab lines with durable copper piping for stronger water flow and long-lasting reliability.
Why Older San Diego Homes Need Copper Repiping
In San Diego, most homes built before the mid-1990s have under the slab copper or polybutylene (Quest) or early-generation PEX piping. These materials degrade quickly in our region’s hard water and coastal air, leading to pinhole leaks, rusty water, and frequent pressure fluctuations.
We’ve repiped homes across neighborhoods like Clairemont and Chula Vista, where pipes failed early even after leak repairs. New Copper solves the root of the issue for 40-50 years:
- Hard water resistant — Copper stands up to scale, unlike PEX.
- Corrosion-proof — No rust, no buildup, no flakes in your tap
- Stable pressure — No more surging water or uneven faucet flow
- Better longevity — A proper copper repipe lasts for years or more, with fewer emergency repairs.
Copper isn’t a trend. It’s what lasts
Signs You Need a Repipe in San Diego?
Most homeowners in San Diego are unaware that they need a full repipe until the damage is already done. Pipe leaks, weak pressure, and rusty water are just symptoms of a larger issue. Here’s how to spot the real problem before it costs you thousands in repairs:
1. You're Fixing Leaks Every Year
If you’ve experienced more than one leak in the past 12 months, especially from PEX or old Quest plastic piping, your plumbing system Leaks may not be isolated. It’s failing. Temporary repairs won’t hold forever.
2. Water Pressure Drops Without Warning
Inconsistent or low water pressure typically indicates corrosion or mineral buildup within old copper pipes. The issue won’t clear up with a new low-flow showerhead..
3. Your House Was Built Before the 1990s
Most homes built before 1990 used under-the-slab or plastic piping (Quest plastic piping), which degrades faster than modern copper piping. If you’re seeing signs and your house is approaching 40 years old, don’t ignore it.
4. Discolored, Metallic-Tasting Water
Is brown or yellow water coming from the taps? That’s internal pipe corrosion. If you’ve ruled out the water heater, it’s the pipe walls themselves flaking into your water.
5. Your Slab Has Been Jackhammered Before
Have you already gone through a slab leak repair? That’s a warning shot. When underground pipes fail once, the rest usually follow copper repiping to avoid future breakage and water damage.
6. Water Heater and Fixture Problems Keep Returning
Scaling, clogs, and early water heater burnout are often traced back to failing pipes. If you’ve replaced your toilet, water heater, or shut-off valves more than once, it’s time to check what’s feeding them.

Resistance to corrosion and pinhole leaks

How Our Copper Repipe Works Start to Finish
When it’s time to repipe, precision matters. We don’t just rip out old pipes and replace them with copper; we follow a clean, efficient process designed to minimize disruption and maximize long-term performance. Here’s how a typical copper repipe works when you hire us in San Diego:
Copper vs PEX
Most San Diego homeowners are unaware of the type of piping running through their walls until a leak forces them to discover it. Here’s a clear breakdown of the three most common pipe types we find during repipe jobs and why copper wins every time:
PEX and Polybutylene:
Polybutylene: Installed from the 1980s to the early 2000s, these flexible plastic pipes fail at fittings and degrade when exposed to chlorine. We frequently encounter leaks in attics, walls, and behind fixtures, particularly in flipped homes and tract housing throughout Clairemont and La Mesa. Temporary repairs are common, but long-term reliability is poor.
Copper:
We install Type L and Type M copper piping, which is rigid, pressure-resistant, and non-reactive. It doesn’t scale, doesn’t corrode, and holds up for 50+ years. It’s the only material we use for full-home repipes in San Diego because it consistently outlasts plastic and steel, even under high-pressure, challenging water conditions.

Frequently Asked Questions – Copper Repiping
Q 1: . How do I know if my home needs a full repipe?
If you’re dealing with repeated leaks, discolored water, or low pressure, and your home was built before the 1990s, you’re likely due. Older homes in San Diego were built with under-the-slab copper or plastic piping that breaks down fast in our water conditions.
Q 2: Will I need to move out during the repipe?
Nope. We work in sections and restore water at the end of each day, so you can stay home while we work. Most full-home repipes take 2–3 days, depending on the size and layout.
Q 3: What if I’ve already repaired a few leaks? Do I still need a repipe?
Yes, if you’ve had more than one leak in the same system, more are likely to follow. A copper repipe costs less in the long run than repeated leak repairs, wall damage, and mold remediation.
Q 4: Can you also replace shut-off valves and water heater connections during the repipe?
Absolutely. We’ll replace failing toilet shut-offs, angle stops, and water heater lines as part of the job, ensuring your entire system is solid from the inlet to the fixtures.
Q 5: How long does a full copper repipe take?
Most single-family homes are completed in 1–2 days, depending on layout and size.
Q 7: Will copper repiping improve my water pressure?
Yes — replacing old galvanized lines greatly increases water pressure and flow.
Q 8: What type of copper do you use?
We use Type L copper, the industry standard for durability and long life.
Q 9: Do you repair walls after repiping?
Yes — wall access is patched and sealed as part of the service.
Q 10: How long does copper piping last?
High-quality copper piping can last 40–50+ years with proper installation.
Q 11: Should I replace all pipes at once or just sections?
A full repipe is the most reliable solution. Patching old piping leads to more leaks later.
