Bay Area Pricing
What a Whole-House Repipe Costs, by Home Size
Bathroom count is the best single predictor of repipe cost, because it tracks how many fixtures and how much pipe the job involves. The bands below are the Bay Area baseline: PEX-A, crawl space, single storey. Adjust with the factors underneath, or run the calculator for your exact house.
| Home size | Typical range | What this covers |
|---|---|---|
| 1–2 bathrooms | $6,100 – $12,000 | Most cottages, condos and smaller single-storey homes. Usually a one-day install. |
| 3–4 bathrooms | $10,500 – $16,500 | The typical Bay Area family home. One to two days depending on access. |
| 5–6 bathrooms | $14,900 – $22,000 | Larger and custom homes with long runs and multiple zones. Two days is normal. |
What moves your number off the baseline
- Copper instead of PEX-A — adds roughly 18–22%. Buys a 30-year parts and labour warranty rather than 25.
- Slab foundation instead of a crawl space — adds roughly 30–38%. Lines reroute through walls and attic instead of running underneath.
- A second storey — adds roughly 12–18%. Three or more storeys, 22–30%. Upstairs lines route through the first-floor ceiling.
- Permit fees — $500–$1,500 depending on the city, and not included in the bands above. We pull the permit and schedule the inspection either way.
Worked example: a 3-bathroom, two-storey home on a slab lands around $15,300–$22,800 — the 3–4 bathroom band, plus the slab and second-storey adjustments.
Other plumbing projects
| Project | Typical range | What moves the price most |
|---|---|---|
| Whole-house gas repipe | $1,800 – $18,000+ | Appliance count and run length first, then black iron versus CSST, slab versus raised, and storeys. |
| Sewer line replacement | $3,500 – $21,500+ | Line length and bathroom count, then cast iron versus ABS, and whether the run is under a slab. |
| Sewer lateral replacement | $4,500 – $18,000+ | Length and diameter, trenchless pipe bursting versus open cut, and the condition of the existing lateral. |
| Water service line | $3,200 – $16,000+ | Run length from meter to house, depth, poly versus copper, and obstacles such as driveways and mature trees. |
| General plumbing repairs | $100 – $8,000+ | Spans 9 categories and 50+ services, so run the calculator — a hose bib and a tankless conversion sit at opposite ends. |
What these estimates include
Every range is an installed price, not a materials quote: labour, fittings, and drywall patch and texture where walls are opened. Repipes carry our parts and labour warranty, 25 years on PEX and 30 on copper. Permit fees are the one thing quoted separately, because they are set by your city.
Getting from a range to a firm number
These bands are built from the same pricing model behind the calculators above, so running your own house takes about a minute and narrows things considerably. For a fixed written price a specialist walks the job, confirms scope and puts it in writing, with no obligation.
Common Questions
Cost Calculator FAQ
How accurate are these calculators?
Our calculators use real market data and typical job conditions to give you a reliable range. Final pricing is confirmed during your free in-home assessment — but most estimates land within the range shown.

Which calculator should I use?
If you're replacing water pipes throughout your home, start with the Repipe Calculator. For gas lines, use the Gas Repipe Calculator. For traditional sewer issues, choose the Sewer Repipe Calculator.
