When something goes wrong fast in a Allentown home, it's usually one of these. Here's what to do first.
- Sewage backing up into the basement: stop using water in the whole house. See sewer backup.
- Pipe frozen or burst: close the main shutoff and open a faucet. See burst pipe.
- Leak in a rowhouse wall: shut the main and tell the neighbor on that side.

Common Plumbing Problems in Allentown Homes
Allentown's water system is run by Lehigh County Authority. LCA does not soften the water and notes that calcium and magnesium are prevalent in the Lehigh Valley's groundwater sources, so hardness depends on your service area. It publishes reports by address on its quality map.
The median Allentown home was built in 1952. Permits come from the city's Bureau of Building Standards and Safety, which began enforcing the 2021 International Plumbing Code on January 1, 2026.
Checking Hardness at Your Allentown Address
Lehigh County Authority leaves softening to the customer and publishes water quality by address on its quality map. Look yours up before buying equipment. If scale is a steady problem, LCA's own advice is to talk to a plumber about a water softener.
Before a Lehigh Valley Cold Snap
- Shut off and drain outdoor faucets from the inside valve before the first hard freeze.
- Insulate pipes along outside basement walls and in crawl spaces.
- In a rowhouse, pay attention to pipes on the end wall and in the rear addition.
- Find the main shutoff, usually where the water line enters the basement. See frozen pipes.
Old Cast Iron and Galvanized Pipe
With a median home built in 1952, corroded stacks and narrowed supply lines are common.
What Affects Plumbing Costs in Allentown
No plumber can quote a firm price before seeing the problem. These are the things that move the cost of plumbing work in Allentown.
- Old pipe. Repairs on 1950s and older plumbing often extend past the failed section.
- Rowhouse access. Tight basements and shared walls add labor.
- Finding the problem. Leak locating and camera inspections are separate steps, but they keep the repair itself small.
- Time of day. Many companies charge an after-hours, weekend or holiday fee.
- Permits. When a job needs one, it comes from City of Allentown Bureau of Building Standards and Safety, and the plumber usually pulls it.
- Ask for the arrival fee before the plumber heads out, and for the repair price in writing before work starts.
How to Find a Licensed Plumber in Allentown
These checks take a few minutes and prevent most bad experiences, whichever Allentown plumber you end up hiring.
Check the Allentown License
Pennsylvania does not license plumbers statewide. The City of Allentown licenses journeyman and master plumbers through its Plumbers' Licensing Board, and a plumbing permit has to be applied for by a licensed master plumber. Ask for the Allentown license number before work starts.
What Allentown Exempts From a Plumbing Permit
In Allentown, no permit is needed to repair the working parts of a faucet or valve, clear a stoppage, or replace a defective faucet or valve, as long as the piping is not altered. Other plumbing work needs a permit from a licensed master plumber, or from the owner-occupant of a single-family home.
What to Ask on the Phone
- What is the arrival window?
- Is there a service, trip or after-hours fee?
- For an emergency, will you stop the damage first and quote the permanent repair before starting it?
- What is your license number?
