Start with the scope, not the number
Your quote depends on the size and layout of your house, the pipe material and what the plumber includes. Until you know those three things, a single total tells you very little, so the rest of this page breaks them down.
What’s inside a repipe quote
A complete quote for a Whittier home usually covers these items, and a good one lists them separately:
- New supply lines from the main to every fixture, in PEX or copper
- New shutoff valves at sinks and toilets, plus connections at the water heater
- The city plumbing permit and inspection
- Opening the walls or ceilings where lines need to reach fixtures
- Drywall patching, and sometimes texture and paint
- Haul-away of old pipe and debris
The item most often left out is wall repair. If a quote says “patching by others,” you’ll need a separate drywall contractor, and that cost belongs in your comparison.
What makes one house cost more than another
Number of bathrooms and fixtures: each fixture needs its own run, so a three-bath house has far more pipe and fittings than a one-bath house of the same size.
One story or two: lines to an upstairs bathroom have to travel through floors and walls, which takes more time and more openings.
Foundation and access: a raised foundation with a roomy crawlspace is usually the easiest to work from. Slab houses route the new lines through the attic, which is fine when the attic is accessible and slower when it’s tight.
PEX or copper: copper costs more in materials and labor because every joint is soldered, while PEX bends around corners with fewer fittings.
The main line: replacing the pipe from the meter to the house adds digging, but it’s often the same age as the pipes inside.
Reading two quotes side by side
Put the quotes in a simple table with one row per item from the list above, and mark what each includes. Then compare these points:
- Is the pipe material and brand named, along with the pipe sizes?
- Who pulls the permit, and is the fee in the price?
- Is drywall patching included, and does that include texture and paint?
- What’s the warranty on labor and materials, and is it written?
- How many days will the work take, and will you have water each evening?
If one quote is double the others, it’s worth a second look. But if it’s half, check what’s missing, because the gap is usually a permit, wall repair or the main line.
Paying for a repipe
California limits the down payment on a home improvement contract to $1,000 or 10 percent of the price, whichever is less. Progress payments should match work that’s actually been done. Never pay the full amount before the final inspection passes.
