Montgomery County housing stock runs old in places. Cast iron drain stacks in Ambler and Lansdale, galvanized supply lines in older Pottstown rowhomes, and sump pumps working overtime near the Schuylkill all generate steady plumbing calls. The companies below handle that mix day in and day out.

1. Len the Plumber Heating & Air, LLC

Based at 207 Witmer Rd in Horsham (19044), Len the Plumber Heating & Air is the largest operation on this list by review volume, with 4.8 stars across 3,957 reviews. They cover plumbing, drain and sewer work, heating and air conditioning across Southeastern Pennsylvania and the Delaware Valley. Their own site points to more than 30 years of service and same-day availability seven days a week, which matters when a main shutoff fails on a Sunday. For Horsham, Hatboro and Upper Dublin homeowners, they’re one of the few names with that kind of bench depth.

• Same-day service offered seven days a week
• Plumbing, drain and sewer, heating and cooling under one roof
• 4.8 stars from 3,957 Google reviews

Best for: Emergency plumbing and drain calls that can’t wait until Monday.

2. Carney All Seasons

Carney All Seasons works out of 900 Old Bethlehem Pike in Line Lexington (18932), just over the county line but well within reach of Lansdale, Hatfield and North Wales. They hold a 4.9 rating from 2,736 reviews, the strongest combination of score and volume on this list. The company describes itself as “the plumber that other plumbers recommend,” and the work spans plumbing, heating, air conditioning, geothermal and generators. Their Maintenance Club bundles three annual visits covering heating, cooling and whole-home plumbing, plus a discount on repairs.

• Maintenance Club with three visits a year and 10% off repairs
• Plumbing paired with geothermal and generator work
• 4.9 stars from 2,736 Google reviews

Best for: Upper Montgomery County homeowners who want plumbing and HVAC handled by one contractor.

3. Best Choice Plumbing & Heating

Best Choice Plumbing & Heating has been operating since 1996 and carries 4.8 stars across 2,704 reviews. They serve Pennsylvania and New Jersey with plumbing, HVAC, drain cleaning, excavation and water heater work, and they advertise 24/7 service with free estimates. Excavation capability is worth noting, since buried lateral replacements in older Montgomery County neighborhoods usually need a company that owns the equipment rather than subbing it out. Financing is available through their site.

• In business since 1996, serving PA and NJ
• Excavation and sewer lateral work in house
• 4.8 stars from 2,704 Google reviews

Best for: Sewer line replacement and larger jobs that need digging.

4. Avanti Plumbing & Drains Inc

Located at 284 B W Ridge Pike in Royersford (19468), Avanti Plumbing & Drains holds a 4.9 rating from 1,626 reviews. Google lists them under plumbing, drainage service and gas installation, so gas line work sits alongside the usual drain and fixture calls. Their Ridge Pike location puts Collegeville, Phoenixville-adjacent addresses and the western townships inside a short drive. Gas appliance hookups are a permit item in most municipalities, so having a plumber who does them routinely saves a round of scheduling.

• Gas installation service listed alongside plumbing and drainage
• Western Montgomery County base on Ridge Pike
• 4.9 stars from 1,626 Google reviews

Best for: Gas line runs for ranges, dryers and outdoor grills.

5. PlumbPRO Services

PlumbPRO Services sits at 250 Railroad Ave in Ambler (19002) and rates 4.9 stars over 1,141 reviews. They present themselves as a neighborhood plumbing and HVAC company with decades of service and deep ties to the Ambler area. Their Service Partner Plan is the maintenance option for homeowners who’d rather catch a weeping valve than mop a basement. Ambler, Blue Bell, Whitpain and Upper Dublin addresses are their core territory.

• Service Partner Plan for ongoing maintenance
• Plumbing and HVAC from one local crew
• 4.9 stars from 1,141 Google reviews

Best for: Ambler-area homeowners who want a long-term relationship, not a one-off visit.

6. Total Plumbing & Drain Cleaning

Total Plumbing and Drain Cleaning is locally owned and covers residential and commercial properties across Southeastern Pennsylvania and New Jersey, with a 4.9 rating from 985 reviews. The detail that stands out on their site is emergency coverage seven days and seven nights a year-round, billed at non-emergency pricing. A midnight burst pipe in an unheated Pottstown basement is exactly the scenario that pricing policy is written for. They also handle sewer and drain work for commercial buildings.

• Emergency service 365 days a year at non-emergency pricing
• Residential and commercial sewer and drain work
• 4.9 stars from 985 Google reviews

Best for: After-hours emergencies where overtime billing would otherwise hurt.

7. Valdel Plumbing

Family-owned Valdel Plumbing operates from 2431 Potshop Ln in Norristown (19403) and holds 4.8 stars across 1,086 reviews. They serve Montgomery, Bucks, Chester and Delaware counties, concentrating on residential work: drain cleanings, garbage disposals, toilet repairs, leaks and no-hot-water calls. That everyday repair focus suits the older Norristown and West Norriton housing stock, where small fixes outnumber full repipes. If your list of problems is three minor items rather than one large project, they’re a sensible first call.

• Family-owned, Norristown based
• Everyday residential repairs: drains, disposals, toilets, leaks
• 4.8 stars from 1,086 Google reviews

Best for: Routine residential repairs around Norristown and the 19403 area.

8. Platinum Plumbing and Heating, Inc.

Platinum Plumbing and Heating is at 319 W Ridge Pike in Royersford (19468) with a 4.9 rating from 900 reviews. Google categorizes them as an HVAC contractor, air conditioning contractor and repair service alongside drainage work, so cooling season calls sit next to plumbing on their schedule. Two strong Ridge Pike options in Royersford gives western county homeowners a real second quote without driving the search outside the area. Remember that any technician handling refrigerant needs EPA certification, covered further down.

• Plumbing, heating, air conditioning and drainage in one shop
• Royersford location serving the western townships
• 4.9 stars from 900 Google reviews

Best for: Combined plumbing and AC repair at the same address.

9. Plumb it Heat it Cool it

Based at 2117 W Main St in Norristown (19403), Plumb it Heat it Cool it carries 4.9 stars from 850 reviews. The listing covers plumbing, air conditioning installation and repair, and drainage service, which is a practical mix for homes with aging systems on both sides. West Main Street puts them close to Jeffersonville, Audubon and the Norriton townships. Smaller review counts aren’t a knock here, since the rating has held near the top of the range.

• Plumbing plus air conditioning repair and installation
• Central Norristown location
• 4.9 stars from 850 Google reviews

Best for: Homeowners replacing an older system and fixing plumbing in the same visit.

10. TLC Drain, Sewer, and Water Cleanup

TLC operates from 241 King Manor Dr in King of Prussia (19406) and rates 4.8 stars across 854 reviews. Their categories are different from everyone else on this list: water damage restoration, drainage, fire damage restoration and septic system service. That makes them the name to know when a failure has already flooded a finished basement, because the cleanup and the drain repair come from the same crew. Septic service also matters in the county’s less densely sewered townships.

• Water damage cleanup paired with drain and sewer repair
• Septic system service for properties off public sewer
• 4.8 stars from 854 Google reviews

Best for: Flooded basements, sewer backups and septic problems.

What Plumbing Work Typically Costs in Montgomery County

Prices move with access, materials and how fast you need someone, so treat these as planning ranges rather than quotes. Most local plumbers charge a diagnostic or trip fee that’s often credited toward the repair.

• Service call or diagnostic: typically $59 to $150, frequently waived if you approve the work
• Drain cleaning (single fixture): usually $150 to $450, more if a main line cleanout is involved
• Standard 40 to 50 gallon water heater replacement: commonly $1,600 to $3,200 installed; tankless runs higher
• Toilet replacement: often $350 to $800 including the fixture
• Sewer lateral repair or replacement: frequently $4,000 to $15,000 depending on depth, length and whether a street cut and restoration is needed
• Sump pump replacement: generally $600 to $1,500

Overnight, weekend and holiday calls carry a premium at most companies, though a few advertise flat pricing around the clock. Get the fee structure in writing before the truck rolls.

Questions to Ask Before You Hire a Plumber

1. Are you registered with the Pennsylvania Attorney General’s office, and what’s your registration number?
2. Does my municipality license plumbers, and are you licensed there?
3. Can you send a certificate of insurance showing coverage that’s current today?
4. Who pulls the permit, and which inspection agency covers my township or borough?
5. Is the quote flat-rate or time and materials, and what happens if you open the wall and find more?
6. What’s the warranty on labor, and separately on the parts you install?
7. If refrigerant is involved, does the technician hold EPA Section 608 certification?

Pennsylvania Rules Worth Knowing Before Work Starts

Pennsylvania does not issue a statewide license for plumbing, HVAC or electrical work, though individual municipalities may license locally, so the answer changes between Lower Merion and Limerick. Under the Home Improvement Consumer Protection Act, contractors doing home improvement work must register with the Attorney General’s office, and any job over $500 needs a written contract. Permits are issued under the Uniform Construction Code by each municipality or its appointed inspection agency, not by the state.

If a technician is handling refrigerant on an AC or heat pump, they need EPA Section 608 certification. Rules change, so confirm current requirements with the agency and your municipality before signing anything.

Frequently Asked Questions

Do Plumbers in Montgomery County Need a State License?

No, Pennsylvania does not issue a statewide plumbing license. Licensing happens at the municipal level, so some boroughs and townships require a local plumbing license and others do not. Every home improvement contractor still has to register with the Attorney General’s office, and a written contract is required for jobs over $500.

How Much Does an Emergency Plumber Cost After Hours?

Expect a premium of roughly 1.5 to 2 times standard rates at most companies, though a few advertise the same pricing around the clock. One company on this list states it bills emergency calls at non-emergency pricing, 365 days a year. Always confirm the after-hours fee on the phone before dispatch.

Who Issues the Plumbing Permit for My Job?

Your municipality or its appointed third-party inspection agency issues permits under the Uniform Construction Code. Water heater swaps, gas line work, repipes and sewer laterals commonly require one. Your plumber usually pulls it, but confirm that in the contract so the inspection doesn’t get skipped.

How Many Quotes Should I Get for a Sewer Line Replacement?

Three is the practical number for a job in the $4,000 to $15,000 range. Ask each contractor to include a camera inspection recording, the repair method (open trench versus trenchless) and who handles street restoration if a cut is needed.
