This repipe cost calculator gives a Philadelphia-area budget for replacing the water piping in a rowhouse, twin, detached house or larger building, with the L&I permit fee and the pipe material the code allows. No contact details needed, and the result changes as you answer.

## Estimate your building

The range depends only on the building, how much of it is repiped and, for PEX, the material. Floors, bathrooms and plaster show where in the range a home tends to land; permits and add-ons are shown as their own lines.

## How the estimate works

The ranges are typical Philadelphia-area ranges for a whole-house repipe, drawn from local and regional project figures. They are budgeting figures, not a quote. No answer you give changes them: there are no multipliers and no square-foot scaling, and the upper end stays open because larger and copper jobs run past it. Floors, bathrooms and plaster are shown as drivers that push toward the high end.

The permit line comes from the City of Philadelphia Department of Licenses and Inspections [summary of construction permit fees](https://www.phila.gov/media/20260729134349/PG_012_INF_Summary-of-construction-permit-fees-Eff-1.1.2025-Rev-7.2026.pdf) and its [plumbing permit page](https://www.phila.gov/services/permits-violations-licenses/apply-for-a-permit/building-and-repair-permits/get-a-plumbing-permit/), worked out from the fixture count you enter. The material rule comes from L&I's [summary of Philadelphia plumbing code amendments](https://www.phila.gov/media/20240226150355/PB_022_FAQ_Summary-of-2018-Philadelphia-plumbing-code-amendments.pdf). The service line figure, curb stop charges and programs come from the [Philadelphia Water Department](https://water.phila.gov/service-line/) and its [Rates and Charges](https://www.phila.gov/media/20260702162035/PWD-Exhibit-1A-Final-Rates-and-Charges-Clean.pdf). Suburban permit fees are set by each township or borough, so none are shown.

For context on labor: the Bureau of Labor Statistics puts the median wage for plumbers in the Philadelphia metro at $35.99 an hour against $30.67 nationally, about 17% higher ([Philadelphia metro](https://www.bls.gov/oes/current/oes_37980.htm), [United States](https://www.bls.gov/oes/current/oes472152.htm)). A wage is not a billing rate, but it moves every labor-heavy job.

## What you get for each building

| Your answers | The calculator shows |
| --- | --- |
| Whole rowhouse, twin or detached house | $4,000 to $15,000+, a typical Philadelphia-area range. Larger homes and copper jobs can pass $20,000. |
| The same, with PEX chosen | About $4,000 to $10,000 for a typical home in PEX; large homes run higher. |
| 2 to 4 units, mixed-use, or 5+ unit apartment building | No range. The drivers for that building, and a price after a walk-through. |
| Any partial repipe | No range. Which lines are replaced and where new meets old decide the price. |
| Water service line, City of Philadelphia | $3,000 to $12,000, the Philadelphia Water Department estimate, shown as its own line. |
| Main shutoff | No range. Priced after a walk-through. |

### Never inside the range

- The L&I permit, shown as its own line ($50 for up to 7 fixtures in a one- or two-family dwelling)
- A replacement water heater, and new fixtures
- Patching and painting, unless the quote lists it
- Sewer and drain lines, which are a separate job
- The water service line, which is its own project and permit

## Questions about the calculator

### Why does the calculator show a range for a rowhouse or single house but not for a 2 to 4 unit building?

A range is shown only where local project figures support one: $4,000 to $15,000+ for a whole rowhouse, twin or detached house, with larger homes and copper jobs able to pass $20,000. Multi-unit, mixed-use and apartment buildings, and any partial repipe, vary too much with risers, unit shutoffs and access, so the calculator lists what drives the price and leaves the number to a walk-through.

### How is the L&I plumbing permit fee for a repipe worked out?

L&I charges by fixture count. For a one- or two-family dwelling the alteration permit is $50 for the first 7 fixtures and $22.50 for each one after that, so 10 fixtures come to $117.50. Other occupancies start at $189. A $3 city and $4.50 state surcharge are added, and the $100 filing fee is applied toward the final fee.

### Should the service line and the repipe be priced as one job?

Price them as two lines, even when one contractor does both. Inside the city the owner is responsible for the whole service line, and the Philadelphia Water Department estimates $3,000 to $12,000 for a private plumber to replace it, more with a street opening. Check the PWD pilot and main-project programs first, and plan the order so the new line and new piping meet at a new main shutoff.
