Plumbing Services in Philadelphia, PA

Philadelphia plumbing runs the full range, from century-old supply lines to modern fixtures. We handle the whole trade, and we tell you what is actually wrong before any work starts.

The plumbing in a Philadelphia home does more work than most people realize. According to the U.S. Geological Survey, the average American uses roughly 80 to 100 gallons of water a day at home, and every gallon of it moves through supply lines, fixtures, and drains that age year after year. In a city where much of that plumbing predates living memory, small problems become expensive ones quickly, which is why having one plumber who handles the whole system matters.

Guaranteed Plumbing & Heating has run the full plumbing trade across Philadelphia, Bucks County, and Montgomery County since 1990. From a single dripping faucet to a whole-home repipe, from a failed water heater to a gas line, we diagnose the actual problem and fix it right the first time. Below are the plumbing services we run most often, how we approach the work, and what to expect when we arrive.

Why plumbing in Philadelphia is its own kind of job

Two things make plumbing in this city different from plumbing in a newer suburb.

Old supply and drain systems. Much of Philadelphia’s housing was plumbed with materials that have since reached the end of their service life: galvanized supply lines that narrow with internal rust, cast iron drain stacks that scale and lose diameter, and original gas piping with fittings that loosen over decades. The Philadelphia Water Department maintains more than 3,000 miles of sewer across the city, much of it serving neighborhoods where the homes are as old as the mains. A plumber who works mostly on newer suburban housing is not equipped for what is behind these walls. We are.

Small problems waste a lot of water. The leaks people ignore add up faster than they think. The EPA’s WaterSense program estimates that household leaks waste close to a trillion gallons of water nationally each year, and that one in ten homes has leaks running 90 gallons a day or more. A dripping faucet, a running toilet, or a pinhole in an aging supply line is not just an annoyance, it is money going down the drain and, in an old house, often a sign of a larger problem developing. We find the source rather than chasing the symptom.

This is why a patch is not always a repair. Stopping today’s drip is easy. Understanding why an old galvanized line is failing, whether a single fixture is the problem or the whole system is near the end, is the part that saves you from paying twice.

Plumbing services we run in Philadelphia

We handle the full residential and small-commercial plumbing trade rather than specializing in one piece of it. The services we run most often:

  • Plumbing repair and service

    The everyday problems, leaks, drips, running toilets, low pressure, faulty fixtures, diagnosed and repaired. The bread and butter of keeping a home running.

  • Water heater repair and replacement

    Tank and tankless, repair when it makes sense and replacement when it does not, sized correctly for your home and your hot water demand.

  • Leak repair

    From a dripping fixture to a hidden line leak to a ceiling stain spreading from the floor above, we locate the source and repair it rather than guessing.

  • Water line repair and replacement

    Aging supply lines and underground water service runs that leak or lose pressure, repaired or replaced with excavation when the line cannot be saved.

  • Gas line service

    Inspection, pressure testing, repair, and installation of gas lines for heating equipment, water heaters, and appliances, done under the proper permit.

  • Bathroom and kitchen plumbing

    Fixture replacement, rough-in for remodels, and code corrections on older installs, coordinated with your contractor when needed.

  • Whole-home repiping

    When galvanized supply lines have corroded past the point of patching, we replace them and bring back both pressure and water quality.

  • Plumbing code violations

    Correcting failed inspections and bringing older installs up to current code, with the documentation you need.

  • Emergency plumbing

    Burst pipes, major leaks, and backups, routed for fast dispatch through our 24/7 answering service.

Pricing, coupons, and financing

We do not publish flat plumbing prices, because the right diagnosis and the right scope are different on every job. Pricing is confirmed on-site after diagnosis and before any work begins. We do not change the price after the fact.

We run rotating coupons on services like water heater work and other repairs. Coupons must be mentioned at the time of scheduling, are limited to one per household, apply Monday through Friday between 8 a.m. and 4 p.m., and cannot be combined with other offers. See the full list on our coupons page.

  • Repair or replace.

    When a repair on aging plumbing runs into real money, we lay out the honest comparison rather than steering you toward the bigger ticket. Sometimes a repair is the right call, and sometimes replacing a failing system saves you from paying for the same problem twice.

  • Financing.

    For larger jobs like repipes, water line replacements, and water heater conversions, we offer instant approval financing through GoodLeap.

What to expect when we arrive

When you call 215-342-7200, this is how a typical plumbing call runs.

  • 1. Triage on the phone.

    We ask what the problem is, when it started, and whether anything, age of the home, recent work, recurring history, might be relevant. That tells us what to bring.

  • 2. Diagnostic on arrival.

    Before any work, the plumber looks at the actual problem and the system around it, rather than fixing the symptom and missing the cause. In an old house, the visible problem is often not the whole story.

  • 3. The real cause, explained.

    We tell you what is wrong and why, in plain terms, and what it takes to fix it. If we find a bigger underlying issue, you hear about it straight rather than after the fact.

  • 4. The work, done right.

    We carry the common parts and fittings on the truck, including the transition fittings older Philadelphia homes need, so most jobs finish in a single visit. When a part has to be ordered, we tell you the timeline up front.

  • 5. Clean cleanup and paperwork.

    We do not leave a mess behind, and you get an itemized invoice describing exactly what was done.

Credentials that matter for plumbing in Philadelphia

You should not let an unlicensed plumber work on your supply lines, drains, or gas in this city. Per the Philadelphia Department of Licenses and Inspections, a licensed Master Plumber must oversee plumbing work, hold an active license, be current on City taxes, and carry current insurance on file with L&I. We have been operating under that standard since 1990.

  • BBB accredited

    Listed as accredited on the Better Business Bureau.

  • Insured for the work we do

    Liability and workers’ compensation coverage on file with L&I.

  • Family-owned and operated

    In business in the Philadelphia area since 1990.

Frequently asked questions about plumbing services in Philadelphia

Do you handle both small repairs and big plumbing jobs?+

Yes. We run the full trade, from a single dripping faucet or running toilet to a whole-home repipe or a water line replacement. Having one plumber who knows your home across all of it saves you from re-explaining the house every time something comes up.

Can you work on older Philly row homes with galvanized and cast iron?+

Yes. That is the majority of what we do. We carry the transition fittings and the cabling and jetting tools these older systems need, and we know how galvanized supply lines and cast iron drains fail so we can diagnose them correctly.

My water pressure is weak upstairs. What causes that?+

In older Philadelphia homes, weak upstairs pressure is frequently corroded galvanized supply lines that have narrowed from the inside. We confirm the cause and tell you whether it is a localized repair or whether the supply lines are due for replacement.

Do you give free estimates?+

Yes. We run free estimates and confirm pricing on-site after diagnosis, before any work begins. The price does not change after the fact.

Do you offer emergency plumbing service?+

Yes. Burst pipes, major leaks, and backups are routed for fast dispatch through our 24/7 answering service, where a real person answers the call.

How do I know whether to repair or replace?+

It comes down to the age and condition of the system and what the repair costs against the cost of replacement. We give you the honest comparison and let you make the call, rather than pushing the bigger job.

Do you pull permits for plumbing work?+

Yes. Most plumbing work in Philadelphia requires a permit pulled by a licensed Master Plumber. We pull the permits as part of the work, not as an upcharge after the fact.

Do you serve plumbing in Bucks County and Montgomery County?+

Yes, both, with the same crews dispatched out of our Northeast Philadelphia office on Cottman Avenue. Suburban systems differ from city row homes, but the full plumbing trade is the same, and we handle all of it.
