Plumbing Companies in Philadelphia, PA — How to Find and Verify One (2026)

How to find licensed plumbing companies in Philadelphia, PA — what state and city licenses to require, what Philly plumbing companies charge, and how Philadelphia's old building stock shapes local plumbing work.

Quick Answer: Plumbing companies in Philadelphia must hold a Pennsylvania plumbing license and a City of Philadelphia plumbing license — both are required for permitted work within city limits. Rates run $95–$170 per hour for standard residential work. Philadelphia’s extensive stock of pre-war rowhouses and twins, aging lead and galvanized pipe, and cold winters create plumbing issues that require companies with specific Philadelphia experience.

What Licenses Should a Philadelphia Plumbing Company Hold?

Philadelphia has a two-tier licensing structure similar to Chicago:

Pennsylvania state plumbing license — issued by the Pennsylvania State Plumbing Board under the Department of Labor and Industry. This covers Master Plumber and Journeyman Plumber classifications.

City of Philadelphia plumbing license — issued by the Philadelphia Department of Licenses and Inspections (L&I). Philadelphia requires its own license for contractors working within city limits and pulling Philadelphia permits.

Ask for both license numbers before scheduling. Verify the Pennsylvania state license at the Department of Labor and Industry license lookup, and the City license through Philadelphia L&I. A company that holds only the state license cannot legally pull Philadelphia permits.

How to Find a Licensed Plumbing Company in Philadelphia

Step 1: Use a directory filtered to Philadelphia. The Philadelphia metro includes the surrounding counties — Montgomery, Delaware, Bucks, and Chester — but the city itself has distinct licensing and permit requirements from the suburbs. Browse licensed plumbing companies in Philadelphia at PlumberLocator.us — Philadelphia Plumbers.

Step 2: Confirm both licenses before scheduling. Ask for the Pennsylvania state license number and the City of Philadelphia license number. Verify both before committing. For any permitted work inside city limits, both are required.

Step 3: Ask about rowhouse and pre-war construction experience. The vast majority of Philadelphia’s residential housing stock is attached rowhouses and twins built between 1880 and 1960. Working in these structures requires experience with narrow access, shared walls, cast iron drain stacks, and original supply configurations that don’t follow modern layouts.

Step 4: Confirm permits are included. Philadelphia L&I requires permits for water heater replacement, sewer line work, gas line work, and drain relocation. Permit fees vary by job scope. Confirm this is factored into any estimate before signing.

What Services Do Philadelphia Plumbing Companies Offer?

Lead and galvanized pipe replacement. Philadelphia has a very high concentration of homes with lead service lines — the pipe connecting the home to the water main — and galvanized steel interior supply lines. Homes built before 1950 in Philly should be tested for lead. The City of Philadelphia has a Lead Service Line Replacement program; ask any plumbing company you hire about enrollment. Galvanized interior lines corrode from the inside out, reducing pressure and discoloring water, and should be replaced with copper or PEX.

Frozen and burst pipe repair. Philadelphia winters regularly drop below 15°F. Supply lines in exterior rowhouse walls, unheated basements, and uninsulated crawl spaces are vulnerable. If a pipe freezes, shut off the main immediately — thawing often reveals a crack that was hidden while frozen.

Sewer camera inspection and lateral repair. Philadelphia’s older rowhouse neighborhoods have clay tile sewer laterals prone to root intrusion and joint failure. Camera inspection before buying any pre-1960s Philadelphia property is standard. The City of Philadelphia also has a specific sewer lateral program — ask your plumbing company whether your block is eligible for any assistance. For what camera inspection involves, see what is a sewer camera inspection and what does it cost.

Rowhouse and twin drain stack work. Philadelphia’s attached housing stock shares walls with neighbors. Drain stacks run vertically through the house and connect multiple floor drains. Working on these requires care to avoid disturbing shared wall penetrations. Experienced Philadelphia plumbing companies understand these configurations and know when neighbor access or coordination is required.

Water heater replacement and boiler service. Many Philadelphia rowhouses have basements that house both water heaters and boilers. Companies experienced with Philadelphia housing work on both regularly.

Frequently Asked Questions About Philadelphia Plumbing Companies

Does Philadelphia require a permit to replace a water heater?

Yes. The City of Philadelphia Department of Licenses and Inspections requires a permit for water heater replacement. The permit must be pulled by a contractor holding both the Pennsylvania state plumbing license and the City of Philadelphia license. An unlicensed or unpermitted installation creates code violations that surface during property sales.

How do I know if my Philadelphia home has a lead service line?

Homes built before 1950 in Philadelphia are most likely to have lead service lines. You can check the Philadelphia Water Department’s lead service line map at the PWD website, or ask a licensed plumbing company to inspect the service line where it enters the home. If the pipe is dull grey and a magnet does not stick to it, it is likely lead.

What is the Philadelphia L&I license lookup?

The City of Philadelphia Department of Licenses and Inspections maintains a contractor license lookup at licensephila.com. Search by company name to verify active licensure, license type, and any violations on record.

How quickly can a Philadelphia plumbing company respond to an emergency?

Most Philadelphia-area plumbing companies with 24/7 service aim for 1–2 hours within city limits. During severe winter weather when freeze events hit multiple properties simultaneously, response times extend. Call multiple companies simultaneously for emergencies rather than waiting for a callback. For emergency guidance, see how to find a 24-hour emergency plumber near you.
