Recurring leaks, rusty water, and weak pressure often mean the pipes themselves are done. We repipe San Marcos homes in PEX or copper with clean, permitted work and a written material specification — not a patch that fails again next year.
When a home has pinhole leaks in more than one place, discolored water, or pressure that never quite recovers, you’re usually looking at supply pipe that has reached the end of its life. Repiping replaces the aging galvanized or thinning copper throughout the house with modern PEX or new copper — solving the whole problem instead of chasing leaks one fitting at a time.
A good repipe is planned, not improvised. We provide a written material specification, an access plan that minimizes wall openings, permits and inspection, a restoration scope, and pressure testing. Our crews protect your home, work cleanly, and patch access points, so the disruption is far less than most homeowners fear.
Signs your home needs repiping
- Pinhole leaks appearing in more than one location
- Rusty, brown, or metallic-tasting water
- Low water pressure throughout the house
- Galvanized supply pipe in a 1950s–70s home
- Repeated slab leaks in aging copper
- Water temperature swings when another fixture runs
Our Process
- 1
Assess the system
We inspect pipe material, condition, pressure, and leak history to confirm repiping is the right call.
- 2
Specify materials
You get a written spec — PEX or copper — with the reasons it fits your home and California code.
- 3
Plan access
We map the routing to minimize wall and ceiling openings and protect your home during the work.
- 4
Repipe & permit
The crew installs new supply lines, we pull the permit, and the work is inspected.
- 5
Test & restore
We pressure-test the system and patch access points, leaving a clean, documented job.
What’s Included
Every repiping job with North County Pro Plumbing of San Marcos covers:
- A full assessment of pipe material, condition, pressure, and leak history first
- A written material specification — PEX or copper — with the reasons it fits your home
- An access plan that minimizes wall and ceiling openings and protects your home
- Clean staged installation so you keep water for as much of the project as possible
- Permits pulled, inspection scheduled, and a whole-system pressure test
- Drywall access points patched and the job left clean and documented
PEX vs. copper for San Marcos homes
Both are excellent when installed correctly. PEX is flexible, resists the scale and corrosion that hard Vallecitos water inflicts on metal, installs with fewer fittings, and often costs less and finishes faster. Copper is time-proven and rigid, preferred by some homeowners and required in certain conditions. We explain why the selected material fits your building and code requirements rather than defaulting to one — because the right choice depends on your home.
Why get multiple written quotes
Whole-house repiping is a significant project — published ranges reach $4,000–$15,000, and one local source reports copper whole-house repipes averaging around $10,073. That’s exactly why you should compare at least three written quotes with a clear scope: material spec, number of fixtures, access and restoration, permits, and warranty. A low first price that excludes patching or permits isn’t actually the lower total cost.
What Affects the Cost
Repiping cost in San Marcos depends on home size, fixture count, material, access, and restoration. Published ranges run $4,000–$15,000; we give you a written, itemized scope.
- Home size and number of fixtures and bathrooms
- Material — PEX vs. copper
- Single vs. two-story and slab vs. crawlspace access
- Wall/ceiling openings and drywall restoration
- Permits, inspection, and pressure testing

Whole-House Repiping FAQs
Most San Marcos homes are repiped in a few days depending on size, stories, and access. We give you a firm timeline in the written scope, and our crews work in stages so you keep water service for as much of the project as possible.
Both perform well installed correctly. PEX resists hard-water scale, installs faster, and usually costs less; copper is rigid and time-proven. We recommend based on your home and code requirements and explain the reasoning — there’s no one-size answer.
Often yes, when testing confirms corroded, scaled, or undersized supply pipe is the cause. We run a pressure test and check the regulator first so you’re solving the real problem — sometimes low pressure is a regulator or a single restriction, not the whole system.
Almost never. Most San Marcos repipes are done in a few days with water restored each evening, and we stage the work so you keep service for as much of the project as possible. We give you the realistic timeline and daily plan up front so you can plan around it — no surprises.
Usually, yes. We map the routing to reach fixtures through as few openings as possible — often using attic, crawlspace, and closet runs — so a two-story repipe doesn’t mean cutting every wall. The written access plan shows exactly where we’ll open and patch before we start.
