Expect to pay roughly $6,600 to $12,100 to repipe a 2-bath house in Missouri using new PEX pipe. Missouri plumbers earn about $36.06 an hour, a bit more than the US average, so local prices sit a little higher than what you'd pay elsewhere. Just over a quarter of the state's homes (27.2%) went up before 1960, and the typical one dates to 1979, years when galvanized steel water pipe was common. Age alone cannot tell you what pipe is there now. The call puts you through to a repipe company serving your area. It is free for you, and after the company looks at the house, it gives you a fixed price.
Old pipes a repipe replaces
Galvanized steel pipe shows up in a lot of homes built before 1960, since it was the standard material back then. That covers 27.2% of the homes in Missouri.
Another 24.4% went up between 1980 and 1999. Those years overlap the polybutylene era (1978 to 1995) and the first years of Kitec (1995 to 2007). A further 24.0% of homes date to 2000 or later.
When low pressure, discolored water, or leaks turn up in more than one spot around the house, a repipe is generally worth doing, according to a national guide.
Repipe prices for Missouri houses
These numbers are ballpark figures produced by this site's Missouri calculator. PEX is a bendable plastic pipe, with red usually marking the hot lines and blue the cold ones. A crawl space is the low open area you get when a house is built up off the ground on a raised foundation.
| House | Pipe | Rough cost |
|---|---|---|
| 1,200 sq ft, one bath, crawl space | PEX | $4,200 to $7,900 |
| 1,800 sq ft, two baths, crawl space | PEX | $6,600–$12,100 |
| 1,800 sq ft, two baths, crawl space | CPVC | $7,600–$13,100 |
| 1,800 sq ft, two baths, crawl space | Copper | $9,700–$19,300 |
| 2,400 sq ft, three baths, two floors, crawl space | PEX | $8,300–$16,600 |
CPVC is stiff plastic pipe in a cream or tan shade. Copper is a metal pipe joined together with solder.
For this estimate, use your home's size and number of bathrooms rather than its number of bedrooms. A 3-bedroom house usually comes with 2 bathrooms, so use the 2-bath price as your guide.
Slab houses cost more
A slab means a concrete floor poured right onto the ground, with pipes running underneath or inside it. Getting to those pipes takes extra labor, so a house of that same 1,800 sq ft size runs about $8,500 to $16,700 rather than $6,600 to $12,100.
What's inside the quote?
Roughly 70% of what you pay for a repipe goes to labor, according to Angi. Permit fees land somewhere between $50 and $800, a national guide says, so check that your quote covers yours.
For the same job, quotes can swing by $2,000 to $5,000, that guide also found. Get a fixed price for your own house: call, and we will connect you with a repipe company near you. It costs you nothing.
Staying home while the work happens
Most families remain in the home the entire time, Repipe Solutions notes. A house of 1,800 sq ft with 2 baths and PEX usually needs two to three days of work.
Making sure your plumber is licensed
In Missouri, your city or county building department licenses plumbers (Missouri Division of Professional Registration). Before work starts, check the plumber's license with your city or county building department.
Plumbing rules in Missouri for cities and counties
Local governments in Missouri set their own plumbing rules. Building codes there are mostly adopted at the local level. Under state law, any city of 15,000 or more people must set its own plumbing rules and require a permit. A county plumbing law can be adopted by some large counties that are called first class counties. If that county law applies, the work must be done by a licensed plumber, even if you own the house. The exception is minor repairs. If a city has its own plumbing ordinance, it keeps that ordinance.
Private wells supply about 13.5 percent of Missourians, a little below the national figure of roughly 15 percent. Test your well water at least once a year, the state health department advises, and again once the well has been serviced.
