Clogged Drain? We Clear It Completely — Not Just Temporarily
Most people reach for a bottle of chemical drain cleaner and hope for the best. It works — for a few days. Then the drain slows down again, because the real problem was never actually fixed.
A persistent clog is your plumbing system trying to tell you something. It could be years of grease buildup in a kitchen line, a tree root working its way into your sewer pipe, or a collapsed section of drain that no amount of liquid cleaner will ever clear. ONG Plumbing & Heating gets to the root cause — literally and figuratively — and fixes it properly so you’re not calling us again for the same problem next month.
Most drain problems give plenty of warning before they become emergencies. If you’re noticing any of the following, it’s time to call ONG before a slow drain becomes a full backup or a sewage overflow.
Why Choose ONG
Any plumber can run a snake down a drain. ONG goes further. When a clog is persistent or keeps coming back, we use camera inspection to find out exactly what’s causing it — so the fix actually lasts.
The cost of professional drain cleaning in Bethlehem typically ranges from $200 to $300 for common household drains such as sinks, tubs, or toilets. If the blockage is deeper in the plumbing system or in the main sewer line, the cost may range from $250 to $600 or more, depending on the severity of the clog and the equipment required.
Yes, ONG Plumbing offers emergency plumbing services to quickly resolve urgent issues such as burst pipes, severe leaks, and overflowing fixtures.
Recurring clogs usually mean there's an underlying issue that a standard clearing isn't addressing — heavy grease buildup further down the line, root intrusion, a partial pipe collapse, or a belly in the pipe that traps debris. Camera inspection is the most reliable way to find out exactly what's causing it.
Slow drains are usually caused by buildup of grease, soap, hair, or debris inside the pipes. Professional drain cleaning can safely remove these blockages.
Repeated use of chemical drain cleaners can corrode older pipes over time, particularly older metal pipes. They also rarely address the root cause of a clog — they dissolve just enough to restore flow temporarily, which is why the same drain blocks again weeks later. Professional clearing is safer for your pipes and more effective long-term.
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.
