Delaware County homeowners hunting for a plumber in 2026 have deep options between Boothwyn and Media. The ten companies below are ordered by Google rating and review volume, starting with Len The Plumber Heating & Air (4.6 stars, 5,876 reviews) and finishing with Mr. Fix It Plumbing & Heating LLC (5 stars, 303 reviews), with notes on what each one actually handles.

1. Len The Plumber Heating & Air, LLC

Rated 4.6 stars across 5,876 reviews, Len The Plumber Heating & Air runs its local operation out of 7 Chelsea Pkwy #709 in Boothwyn, PA 19061. The company has served Southeastern Pennsylvania and the Delaware Valley for more than 30 years, and it pairs plumbing with drain, sewer, heating and air conditioning work under one roof. Its review count is the largest on this list by a wide margin, which generally reflects a big dispatch footprint rather than a one-truck shop.

Same-day service available seven days a week
Plumbing, drain and sewer, furnace repair and AC under one company
Covers the Delaware Valley from a Boothwyn base near the Route 322 corridor

Best for: homeowners who want a seven-day dispatch option for a burst line or dead water heater.

2. Dream Team – Plumbing, Heating, Cooling, & Electric

At 4.9 stars from 2,429 reviews, Dream Team works out of 436 S Lansdowne Ave in Lansdowne, PA 19050. The company handles plumbing, HVAC, electrical and ongoing maintenance for homeowners across Lansdowne and nearby Delaware County boroughs and townships. Its listed service area reads like a map of the county’s older inner-ring communities, including Havertown, Drexel Hill, Media, Springfield, Broomall, Newtown Square and Wallingford.

Three trades in one call: plumbing, HVAC and electrical
Online booking plus phone scheduling
Strong rating held across a large review volume

Best for: older homes where a plumbing problem turns out to involve the panel or the heater too.

The crews cover emergency calls, drain cleaning, water heater repair, sewer line repair, sump pumps and well pump service. Pricing is quoted flat-rate and approved by the homeowner before any work begins, which removes the meter-running anxiety some people feel with hourly billing.

5. Do It Right Plumbing 610

Rated 4.9 stars across 1,001 reviews, Do it right Plumbing 610 is based at 114 Ridge Ave in Darby, PA 19023 and markets itself squarely as a Delaware County draining and plumbing team. The crew takes both residential and commercial work, from urgent repairs to planned upgrades, and keeps a 24/7 emergency line running. Core services include drain cleaning for slow or backed-up lines, water heater repair and replacement, and leak detection and repair.

Residential and commercial jobs
Work backed by a company guarantee

Best for: eastern Delaware County rowhomes and twins in Darby, Collingdale and Yeadon with recurring drain backups.

6. McLoughlin Service Experts

McLoughlin Service Experts carries 4.8 stars from 770 reviews and works from 8649 West Chester Pike in Upper Darby Township, PA 19082. The company is listed as a plumber, air conditioning contractor, air conditioning repair service and furnace repair service, so a single visit can cover both the water side and the comfort side of a house. Its location on West Chester Pike puts it minutes from Drexel Hill, Havertown and Broomall.

7. Advanced Drains And Underground Solutions

At 4.8 stars from 755 reviews, Advanced Drains And Underground Solutions specializes in the underground work most general plumbers subcontract out, from its base at 122 Baltimore Pike Ste 2R, Springfield Township, PA 19064. The team does hydro jetting, sewer lateral camera inspections, trenchless repair, excavating and septic work. Their own explanation of the problem is useful: cabling a line pokes a hole through the clog, while jetting scours grease, roots and scale off the full pipe wall, then the camera shows you what the pipe actually looks like.

Hydro jetting and camera inspection of sewer laterals
Every estimate and plan given in writing and explained plainly
Text and email communication accepted, which helps deaf and hard-of-hearing customers

Best for: a sewer lateral that keeps backing up every few months instead of staying clear.

8. Walsh Brothers Plumbing and Mechanical Services, Inc.

Walsh Brothers holds 4.9 stars from 610 reviews and operates at 500 Abbott Dr Ste A in Broomall, PA 19008. Google lists the company under HVAC contractor, air conditioning contractor, bathroom remodeler and furnace repair service, a mix that points toward planned mechanical projects as much as emergency calls. The Broomall base sits close to Marple, Newtown Square and Havertown. For a bathroom gut job that needs new supply and waste lines plus mechanical work, that combination of trade categories keeps the coordination in one company.

Best for: bathroom remodels where the rough plumbing and the heating both need touching. See walshbrothersinc.com for current services.

9. R F Bondurant Plumbing & Heating

R F Bondurant Plumbing & Heating earns 4.9 stars from 437 reviews and works from 228 Brooke St in Media, PA 19063, a short walk from the State Street business district. The company is categorized as a plumber, heating contractor and bathroom remodeler, which fits the mix of Victorian-era and early twentieth century homes around Media borough and Nether Providence. A smaller review count usually signals a smaller crew, so scheduling for non-emergency work may take longer than it would with the large dispatch outfits higher on this list.

Media base covering the 19063 area and surrounding townships

Best for: Media-area homeowners who want the same familiar plumber on repeat visits.

10. Mr. Fix It Plumbing & Heating LLC

Mr. Fix It Plumbing & Heating LLC carries a perfect 5-star rating across 303 reviews, the only unblemished score in this group. It is listed simply as a plumber and service establishment, with no storefront address published on its profile, which is common for owner-operated outfits that run from a truck. A clean rating at that review volume is a meaningful signal, though you should still confirm current insurance and any municipal registration before booking.

Plumbing and heating service
Small-operation scheduling, so call early for non-urgent jobs

Best for: straightforward repairs where a single accountable tradesperson matters more than 24/7 dispatch.

Why Local Knowledge Matters for Plumbing in Delaware County

A large share of Delaware County housing was built before 1960, so plumbers here work on cast iron stacks, clay sewer laterals and galvanized supply lines far more often than in newer suburbs. That changes the diagnosis, the repair method and the cost.

Clay and cast iron laterals in Upper Darby, Lansdowne, Darby and Media attract tree roots at every joint, which is why jetting and camera work show up so frequently on local invoices.
Tight rowhome and twin layouts near the Philadelphia line limit access, so repairs often involve basement excavation or trenchless methods rather than open trenching.
Low-lying ground along Darby Creek and Ridley Creek keeps sump pumps and backwater valves in steady demand after heavy storms.
Township-by-township permitting means a plumber who works in Haverford one week and Chester the next has to know two different inspection processes.

What Pennsylvania’s Rules Require Before the Work Starts

Pennsylvania does not issue a statewide license for plumbing, HVAC or electrical work, so licensing happens at the municipal level. Contractors doing home improvement work must still register with the state Attorney General’s office and put any job over $500 in a written contract.

The Home Improvement Consumer Protection Act requires Attorney General registration and a written contract for work over $500.
Permits are issued under the Uniform Construction Code by each municipality or its appointed inspection agency, not by a single state office.
Any technician handling refrigerant needs EPA Section 608 certification, which matters when the same company services your heating and cooling.
Rules change, so confirm current requirements with the agency and your municipality before signing.

Red Flags to Avoid When Hiring a Plumber

The clearest warning signs are a refusal to put the price in writing and pressure to decide on the spot. Both show up in complaints far more often than bad workmanship does.
