Plumbing Repair Budget Calculator

From a leaky fixture to a whole-house re-pipe, plumbing cost spans three orders of magnitude. This calculator scopes the job by material, linear feet, and access to produce a defensible budget range.

How the math works

Whole-house re-pipe with PEX runs $4,000–$10,000 on a typical 2,000 sq ft home; copper is 2×. Sewer line replacement is usually $4,000–$15,000 depending on length and whether trenchless methods work. Slab homes and finished second floors inflate cost because of restoration work.

Insurance sometimes covers sudden failures (burst pipe) but not gradual decline. Many policies exclude water/sewer line leaks outside the foundation — a separate service line rider covers that gap for $50–$100/year.

How to Use

Pick the scope. Fixture-level is $500–$1,500; sewer replacement can exceed $15,000.
Pick material. PEX is the cost-effective modern choice; copper is the premium; cast iron is drain-only.
Enter linear feet for whole-house or line-replacement jobs.
Choose access difficulty. Slab homes and finished multi-story homes add 40–90%.
Apply a regional multiplier — labor varies heavily by metro.

Frequently Asked Questions

Copper vs PEX — what should I choose?

PEX is flexible, faster to install, and immune to pinhole leaks that plague copper in hard-water areas. Copper has a longer proven track record and may provide slight resale appeal. PEX-A is the premium grade for long runs.

What causes pinhole leaks?

Thin-wall copper (Type M) plus aggressive water chemistry (low pH, high chloramine) causes pitting corrosion. PEX repipe often makes sense once a home hits three pinhole leaks in a year.

Trenchless sewer vs traditional dig?

Trenchless (pipe bursting or lining) avoids yard destruction and adds $2,000–$5,000 but saves landscaping and driveway restoration. Lining works if the line has structure; bursting works if the old line can be destroyed in place.

Does homeowner insurance cover this?

Generally only sudden, accidental damage. Gradual deterioration, corrosion, and wear are excluded. Add a service-line rider ($50–$100/yr) to cover water and sewer lines between the house and the street.
