Plumbers in Chester County, PA: borough licenses, wells and septic permits
Updated · KeystoneProGuide editorial team
What should Chester County homeowners know before hiring a plumber?
That the county is large and its rules are split. Chester County has 73 municipalities: one city, 15 boroughs and 57 townships, spread over 750.5 square miles. Plumber licensing, where it exists, is set by those municipalities. Wells and on-lot septic systems, used by homes that are off public water or sewer, are permitted by the county health department. The two together decide who you call.
Who licenses plumbers in Chester County?
The municipality, if it chooses to. Pennsylvania has no state plumbing license, and the Department of Labor and Industry says that local requirements, typically for plumbers, electricians and home improvement contractors, can be learned only from the municipality where the work is done.
West Chester Borough is one that does. Its plumbing chapter adopted the International Plumbing Code for, among other things, the licensing of all plumbers in the borough, and says no one may work there as a master or journeyman plumber without proof of an earlier borough license or of passing an International Code Council examination. A township next door may have no such rule. Ask the code office for your address, and ask the plumber which local license they hold.
The state registration applies regardless. The Attorney General's office says master plumbers doing repairs and installations on private homes are home improvement contractors who must register, and its contractor search can be narrowed to Chester County.
What does the county health department do?
It permits the systems that sit outside many Chester County houses. The Chester County Health Department issues permits for individual and small community on-lot sewage systems and for well construction, and enforces the state's Act 537 rules when an on-lot system is in violation. Its environmental health specialists are assigned by municipality, and the office is on 610-344-6225.
That division is worth knowing when a problem straddles the line. A blocked drain inside the house is plumbing work; a failing drainfield or a new well is a county permit matter, handled with a septic contractor or a well driller.
What if your home has a private well?
Then nobody tests your water but you. Penn State Extension says that, apart from a few county or local ordinances, Pennsylvania has no statewide construction standards for private wells, that most wells have at least one water quality problem, and that owners should test every year for coliform bacteria and every three years for pH and total dissolved solids. It warns against relying on in-home tests by water treatment sellers. The common nuisance problems it names, corrosivity, hardness and iron, are ones that show up in a home's pipes and water heater.
Buying a house with a septic system?
Penn State Extension recommends a real estate septic inspection by a certified inspector, which it says is more detailed than a typical home inspection. It puts the cost in south-central Pennsylvania in 2026 at about $625 to $1,200 with the required pumping, and warns that problems found after closing can cost $10,000 to $60,000 or more to fix.
What do Census figures say about Chester County homes?
That a good share are new. The Census Bureau counts 10.7 percent of the county's 212,491 homes as built since 2010, the highest share of the five counties in this directory, and 12.6 percent as first built in 1939 or earlier. Three in four occupied homes, 75.1 percent, are owner-occupied.
Whatever a house's age, plumbing work done on it today is measured against the state construction code, which now adopts the International Plumbing Code of 2021. The older houses in the county's boroughs and villages are the ones where pipe material is worth checking before any large job.
Who issues plumbing permits, and where do you complain?
Permits come from your municipality: Labor and Industry says more than 90 percent of Pennsylvania municipalities enforce the construction code locally, with their own staff or a certified third-party agency. Complaints about a plumber can go to the Attorney General's Bureau of Consumer Protection through its online complaint forms.
