ONG Plumbing & Heating was founded right here in the Lehigh Valley in 2019. We’re not a national franchise dispatching whoever’s available — we’re a local company staffed by local plumbers who live and work in the same communities you do. We know the housing stock, the common pipe materials in older neighborhoods, the local codes, and the municipal requirements that vary from one borough to the next.
That local knowledge matters. It means faster response times, more accurate diagnoses, and work that’s done to the right code the first time — without delays caused by unfamiliarity with local permit processes or inspection requirements.
Allentown is ONG’s largest service market and home base. From the older row homes in the West End to newer construction in the surrounding townships, our team handles plumbing, heating, cooling, and drain service for Allentown homeowners and businesses every day of the week. With five trucks on the road, response times in Allentown are among our fastest — often well under 60 minutes for emergency calls.That local knowledge matters. It means faster response times, more accurate diagnoses, and work that’s done to the right code the first time — without delays caused by unfamiliarity with local permit processes or inspection requirements.
Bethlehem’s mix of historic homes in the South Side and Northside neighborhoods and newer development across the broader township means a wide range of plumbing challenges — from aging cast iron and galvanized pipe in older properties to modern systems in newer builds. ONG serves residential and commercial customers throughout Bethlehem and Bethlehem Township with the same licensed, guaranteed service we deliver across the Valley.
Easton’s older housing stock — particularly in the historic downtown and College Hill neighborhoods — means sewer line issues, aging water lines, and outdated pipe materials are common calls for our team. ONG provides full plumbing, heating, and drain services to Easton homeowners and businesses, including pre-purchase sewer inspections for buyers in one of the Lehigh Valley’s most active real estate markets.
ONG was built from the ground up in the Lehigh Valley. When you call us, you’re supporting a locally owned business that employs local plumbers, pays local taxes, and is invested in the reputation it has built in this community since 2019. We’re not going anywhere — and every job we do reflects directly on our name.

Yes. ONG provides plumbing, heating, cooling, and drain services to commercial properties, businesses, restaurants, multi-unit buildings, and property managers throughout all of our service areas in the Lehigh Valley.

In outlying communities, response times may be slightly longer but we always provide a confirmed ETA when you call.
The clearest sign is multiple drains slowing down or backing up at the same time. If flushing your toilet causes water to back up in a sink or shower, your main sewer line is almost certainly the issue. Call ONG before it becomes a full sewage backup.
Most straightforward drain clearing jobs take between 30 minutes and an hour. Jobs that require camera inspection or main sewer line clearing typically take one to two hours. We'll give you a realistic time estimate when you call.
Yes. ONG services commercial drains, floor drains, and sewer lines for businesses, restaurants, multi-unit properties, and commercial buildings across the Lehigh Valley.
Yes — and it's more common than most homeowners realize, especially in older neighborhoods. Tree roots naturally seek out moisture and can work their way into small cracks or joints in sewer and drain lines over time. Once inside, they grow and eventually cause a full blockage or pipe collapse. Camera inspection is the only reliable way to confirm root intrusion.
Avoid pouring grease down the drain, use drain strainers to catch debris, and schedule routine drain cleaning to maintain proper flow.
Yes, all technicians at ONG Plumbing are trained professionals and fully licensed and insured for your safety and peace of mind.
You can schedule a service by calling our team directly or by submitting a service request through our website contact form.
