Nassau County’s housing landscape ranges from decades-old Capes in Levittown to waterfront properties in Oyster Bay, and every one of them depends on working plumbing. A burst pipe, a failed boiler, or a needed gas conversion: these problems don’t wait for a convenient moment. Knowing which plumbers in Nassau County actually show up, do the job right, and stand behind their work before an emergency happens can save real time, money, and stress.
Our team evaluated ~30 plumbing companies serving Nassau County homeowners and property managers. We assembled a dataset on each company using the following five criteria:
- Service Quality Score: Our 1.0–5.0 evaluation system measures customer satisfaction, technical skill, and verified professional credentials
- Year Founded: Plumbers with deeper roots in Nassau County’s diverse mix of postwar homes, colonial builds, and newer construction diagnose unfamiliar systems faster and tend to keep the right parts on hand for fewer return trips
- 24/7 Emergency Availability: Whether the company provides a true around-the-clock response, not just a voicemail
- Average Response Time: How quickly a technician typically arrives after the first call
- Service Range: Whether the company covers a broad scope of plumbing work, plus additional home services
Based on our algorithm, we rank-ordered these companies and identified the five best plumbers in Nassau County. The table below breaks down where each stands, with in-depth reviews following.

Scheblein
What separates Scheblein from most Nassau County plumbing companies starts with credentials: Eric Scheblein is a licensed Master Plumber holding NYC Department of Buildings license #1783 with over 35 years of hands-on experience, a level of verified expertise that most local contractors can’t match on paper or in the field. That technical depth translates directly to fewer return visits, faster diagnosis of older or unusual systems, and the ability to handle jobs that a general handyman or smaller operation simply won’t take on. Equally important, Scheblein guarantees a technician on site within 3 hours, any hour of the day or night, every day of the year.
The other thing that sets Scheblein apart in Nassau County is range. Their team handles the full scope of residential plumbing and heating: gas boiler and water heater installation, gas line repair and installation, oil-to-gas conversions, water main repair, backflow preventer testing, new construction plumbing, frozen pipe repair, and complete kitchen and bathroom renovations. When a job reaches beyond plumbing, customers also gain access to HVAC, electrical, and other home services through Skaggs-Walsh, making Scheblein a single point of contact for nearly every system in the home.
Service Quality Score: 4.9
Year Founded: 2006
24/7 Emergency Service: Yes
Avg Response Time: Under 3 Hours
Service Range: Full Residential Plumbing, Heating & All Home Services
Contact: Scheblein website
| Summary of Online Reviews |
| Customers call Eric Scheblein “a master plumber who will do whatever it takes to get the job done right,” praising “comparable pricing, knowledgeable, courteous, on time, and clean” service and calling it “wonderful to have such a reliable plumber you can always count on.” Some reviewers note it can be “tough to get on the schedule” during the busy heating season. |
Gramman Plumbing & Heating
Few Nassau County plumbing companies can claim the kind of track record Gramman has built. Family-owned through three generations since 1948, the company has spent more than 75 years working on Nassau County homes, which means their technicians have seen virtually every variation of postwar boiler, prewar steam system, and mid-century pipe configuration the county has to offer. That institutional knowledge shows up in faster diagnosis, more accurate parts estimates, and a reputation for careful workmanship that has compounded across thousands of local jobs.
Their services cover a wide range of residential and commercial needs, including oil-to-gas conversions, steam and hot water heating systems, radiant heat, boiler installation, water heater replacement, sewer and water main work, drain cleaning, bathroom renovations, pool heaters, fire sprinkler repairs, and backflow testing. Where Gramman falls short of the top spot is emergency coverage: their availability is described as nights and weekends rather than a guaranteed around-the-clock response with a defined arrival window. For a pipe that bursts at 2 AM on a Wednesday, that distinction matters.
Service Quality Score: 4.8
Year Founded: 1948
24/7 Emergency Service: Yes (Nights & Weekends)
Avg Response Time: Same Day
Service Range: Residential & Commercial Plumbing & Heating
Contact: Gramman website
| Summary of Online Reviews |
| Customers praise “on time and dependable” service and consistently note the team “left things cleaner than when they arrived.” Those who have needed after-hours weekday service, however, report that Gramman “isn’t always available for true middle-of-the-night calls,” making them a stronger fit for planned work than unplanned emergencies. |
Platinum Plumbing Service
Platinum Plumbing Service earns its place on this list through consistently strong customer feedback and a reputation for honest, competitively priced residential work in Massapequa and across Nassau County. Owner Pete is hands-on and involved in both the work and customer communication, which tends to produce the kind of accountability that larger operations can struggle to deliver. They are open 24 hours, offer same-day service, and cover a solid range of residential plumbing and heating work, including water heater installation and repair, boiler installation and service, gas conversions, drain cleaning, pipe repair and replacement, bathroom remodeling, backflow preventer installation, and whole-house water filtration.
The main limitation is scope. Platinum is a plumbing and heating specialist, and customers who need HVAC or electrical work handled at the same time would need to source a separate contractor. There is also no verifiable master plumber license or formal credential information publicly available, which can be a meaningful factor for homeowners evaluating complex gas or heating system work.
Service Quality Score: 4.7
Year Founded: 1996
24/7 Emergency Service: Yes
Avg Response Time: Same Day
Service Range: Residential Plumbing, Heating & Water Heater Service
Contact: Platinum Yelp listing
| Summary of Online Reviews |
| Customers praise “affordable, reliable plumbing and heating from certified professionals” and describe the owner as “hands-on, honest, and upfront about pricing.” Those who also needed HVAC or electrical work noted they had to “call a separate company” to handle those trades alongside their plumbing job. |
Varsity Home Service
Varsity has built a strong, long-term reputation across Long Island, earning multiple Best of Long Island awards and maintaining an exceptionally high volume of reviews over more than 60 years in business. For Nassau County homeowners who need both plumbing and HVAC addressed by a single company, Varsity offers a legitimate full-service option, covering emergency plumbing repairs, gas line installation and leak detection, water heater installation and repair, leak and burst pipe repairs, sump pump service, oil-to-gas and electric-to-gas conversions, and full HVAC. They are BBB Accredited and carry 24/7 emergency availability.
The primary drawback for Nassau County customers is geography. Varsity’s home base is in Bohemia, Suffolk County, which puts them at a structural travel disadvantage for calls in western Nassau or near the Queens border compared to companies operating out of Nassau itself. For some jobs and some locations, that added drive time is negligible. For a heating emergency on a cold night, it can be the deciding factor.
Service Quality Score: 4.6
Year Founded: 1962
24/7 Emergency Service: Yes
Avg Response Time: Same Day
Service Range: Full Residential Plumbing & HVAC
Contact: Varsity website
| Summary of Online Reviews |
| Customers describe technicians as “professional, pleasant, and thorough” and praise the team for being “friendly, knowledgeable, and clear about what needs to be done.” Some Nassau County homeowners report experiencing “longer wait times than expected,” pointing to Varsity’s Suffolk County base as the likely cause. |
Tragar Home Services
Tragar fills a specific niche that few Nassau County companies occupy: a single account that bundles heating oil delivery, HVAC service, and plumbing under one roof. That’s convenient for homeowners who want to consolidate home services and have been Tragar oil customers for years. They have operated in Hicksville since 1956, know the local area well, and offer 24/7 availability for HVAC installation and repair, plumbing inspection and installation, water heater service, boiler work, and heating oil delivery.
The reason Tragar sits at the bottom of this list comes down to consistency. Their Yelp rating reflects a meaningful number of customers who reported that emergency calls went unanswered, scheduled appointments were missed or rescheduled multiple times, and warranty issues on installed equipment were slow to resolve. When everything goes right, Tragar customers report solid service. The problem is that enough customers report it not going right, particularly during high-demand winter months, to make reliability a legitimate concern.
Service Quality Score: 4.5
Year Founded: 1956
24/7 Emergency Service: Yes
Avg Response Time: Same Day
Service Range: HVAC, Plumbing & Heating Oil
Contact: Tragar Yelp listing
| Summary of Online Reviews |
| Customers who had positive experiences report that Tragar “called back within 10 minutes and arrived quickly,” with technicians described as “professional and thorough.” A notable share of reviews, however, describe “no emergency service at all” and appointments that “got rescheduled multiple times before the technician never showed up” during high-demand winter periods. |
