A Clear View of the Line That Carries Everything Out of Your Home

The main sewer line is one of the oldest, longest, and least-seen pieces of the home’s plumbing, which is exactly why a periodic inspection of it is so worthwhile.

A sewer line runs from the house out to the municipal main or the septic system, often under landscaping, driveways, and the yard, and it usually does decades of quiet work before anything about its condition becomes visible from the surface.

A sewer inspection is the scheduled point where a licensed plumber evaluates that line and produces a clear read on its condition, so the homeowner has accurate information about what is actually happening underground. Princeton Air’s licensed plumbers have been performing sewer inspections across New Jersey for years. Schedule your sewer inspection with Princeton Air today.


Licensed Plumbers With Experience Across New Jersey’s Sewer Lines

Sewer inspection is a service that draws on experience with the specific sewer conditions, pipe materials, and root patterns that are common in homes across the region.

Our licensed plumbers have inspected sewer lines in homes across New Jersey for years, including properties in Old Bridge Township, Sayreville, and Trenton. Older homes in the region often use materials like clay or cast iron, each with its own wear patterns, and our team knows what to look for in both.

Where Orangeburg piping does exist, we account for its structural limitations, but itโ€™s far less common than the others. Newer construction presents a different set of conditions, and we adjust our approach accordingly.

What a Sewer Inspection Produces for Your Home

A sewer inspection turns the invisible question of “what is my sewer line doing?” into documented, actionable information.

Every sewer line is different, and the inspection reflects what is actually installed and what is actually happening in the line being reviewed. What stays consistent is the value: a homeowner comes out of the inspection knowing what they have.

Without an inspection, homeowners know whether water is moving through drains, which is a narrow view of a line that can be silently developing significant issues. A proper inspection produces a fuller picture: the material and condition of the pipe, the presence of any blockages, root intrusion, scale accumulation, or pipe damage, and the general state of the line as a whole.

Most sewer line problems develop gradually. Roots enter through a crack or joint over several seasons before they grow dense enough to cause a backup. Scale accumulates in cast-iron lines over years before flow becomes noticeably slower. Pipe sections sag or separate over decades. An inspection is the moment when those developing issues are identified, while the options for addressing them are still relatively manageable.

An inspection gives the homeowner the information needed to make sensible decisions about next steps. Some lines show conditions that point to sewer cleaning as the appropriate response. Others show localized damage that warrants a focused repair. Some older lines reveal the kind of broader deterioration that makes full replacement the right long-term call. Without an inspection, those decisions become guesses.

A documented sewer inspection is useful in several situations beyond day-to-day homeownership. For a home being sold, it reassures buyers. For a home being purchased, it reveals issues before they become the new owner’s problem. For insurance or warranty conversations, documentation of the line’s condition is often valuable.

If issues develop later, or if the line needs cleaning or repair at some point after the inspection, the same plumbers have context on what the line looked like during the assessment. That continuity matters for deciding what has changed and what the appropriate response is.

Our Tech Dominic was Awesome!! Thank you so much!!
On time. Completed work on all units … Heater, air conditioner, and hot water heater … Within the time frame.
After a few mishaps, Princeton Air came through and got my AC system running when the temperatures are soaring.

Thanks to Will and my technician, Alberto, for getting everything fixed.
Responsive, knowledgeable, dependable, & honest. Thank you for getting out heat up & running!

Update:10/12/18
Chris S got the heat last year and remembered when he arrived today, asked if it had a problem since. He came back to do a PM on the heater and while he was waiting for me to arrive, he opened up the air conditioner to inspect it and saw the coils were filthy. Took out his hose and cleaned them. Then when done, did the heater PM and then โ€œsaid I just want to verify that ringing noise went away. Your house will cool much faster now!โ€ I really like what Princeton air offers, quality and care, diagnose and fix. Not rushing to get to the next job. Theyโ€™re so good I got the year round service plan.

Update may 2025&2026
Maurice is fantastic.
Prompt and knowledgeable. Great technician.
There was an urgent need for a mold problem to be handled in a bathroom. They quickly identified the problem, tested the seriousness, and took care of it – in a very timely fashion. They communicated with me all along the way so I could fully comprehend what was going on. All the people were very knowledgeable, pleasant and accommodating. My experience with them was excellent, and I would highly recommend them.
Eric M. was prompt, professional, courteous and quite helpful. I become a better consumer when I understand the problem & possible solutions. Eric was willing to answer my questions and made me feel secure that he would follow up to help fix our problem.

New review: 2/6/2018
Notice a problem with the humidity in my home, called and got a service appointment in the same day. Will D came out and sure enough, confirmed there was a problem, explained what exactly was happening, why it was happening and how to check that it was working correctly. His demeanor was pleasant, he was professional and seemed to be quite knowledge!
Great service. Domenic was so helpful and explained everything done.
Jermaine Richmond was very knowledgeable and explained my plumbing issue throughly. Thank you.
Pretty micron air was quick to fix my sewer
Friendly and efficient. Quick response service

Installation of water heater hvac and furnace – very professional and process oriented –
The technician who came was Jonathan Redondo. He was very knowledgeable and did an excellent job! I would highly recommend him .
Christian and Mike were professional, thorough, patient, and kind throughout my heating boiler installation.
Always excellent service with McAllister.
Robert came to check my 2 carbon monoxide detectors, which were very old. I decided to have him go ahead and replace them with smoke detector/ carbon monoxide combination units. He was very polite and efficient .
Jihmy and Asterson did an outstanding job and were extremely professional during a recent installation of a mini split and air handler. They communicated well, kept the house clean and did the job with a level of professionalism and expertise that was refreshing.
Good job
Maurice Gaines who cleaned and serviced my air conditioner was fantastic! He was fast, respectful and very fast with the repairs.

He made me feel like I was getting the full respect and honesty I so needed for something so important and really appreciated the time he took to explain every and answer all my millions of questions. Also Princeton Air communications were fast and accurate , leaving no question unanswered as to timing and confirmation of appointment. Iโ€™m so happy with their staff and with Maurice- heโ€™s a gem!
Thank you!
The young man who came out to fulfill our annual service contract was extremely professional and was very thorough. Although he told us we needed a new ac unit I felt confident that he knew what he was talking about and took the right amount of time in order to make his recommendation. I want him back every year. Unfortunately I forgot his name because Iโ€™m old.

He then had Ricky call us with replacement ac unit recommendations. He was just as professional. He then took the time to visit our condo, take measurements himself and then made recommendations on what size unit to purchase. I really feel he saved us money. He was amazing.

We then were contacted by a gentleman named Steve who was a manager in the service and installation department. Itโ€™s hard to believe but he was just as good as the first two representatives and was an absolute pleasure to work with. He was a true professional and a real asset to your organization. I will always use your company if I can work with this team. Keep up the great work. Thanks for allowing me to spend $8,000.its hard to believe I didnโ€™t even get other quotes because I was so happy with your team.

Recently Princeton Air did a routine maintenance check on our HVAC UNIT. The technician was Dominic McGinley. I must say Mr. McGinley was outstanding. After performing the maintenance and evaluation, he sat down with us and explained his findings in precise detail. He has also taken pictures of everything he found. Dominic was a pleasure with whom to interact. He was professional, friendly, and extremely knowledgeable. He explained everything in terms that we could definitely understand. He is one of the finest technicians that has ever performed preventative maintenance on our equipment. In my estimation he has all of attributes of a first rate Service Technician. Hopefully Princeton Air just what a valuable asset he is for the company. I certainly hope to interact with him many times in the future.
We recently used Princeton Air to install a new heater. They gave us lots of options, explained each one thoroughly, they arrived promptly on installation day and did a great job. The price was the lowest of three companies I contacted for estimates. Five stars!
Always professional and informative.

Why New Jersey Homeowners Trust Princeton Air for Sewer Inspections

A sewer inspection is only as useful as the plumber doing it.

Princeton Air approaches sewer inspections with the care the service deserves: licensed plumbers, real experience with sewer lines across the region, and honest assessment of what the inspection actually reveals.

Every sewer inspection is performed by a licensed plumber. The license is a state-awarded credential that reflects training and accountability, and sewer work is exactly the category where credentials matter.

New Jersey’s housing stock includes homes built across many decades, with sewer lines in clay, cast iron, orangeburg, and more recent PVC installations. Our plumbers have inspected all of them, and they understand how each material ages and what each line’s typical issues look like.

Princeton Air has serviced residential plumbing across the state for more than 50 years. Sewer inspection is one piece of that broader practice, and the perspective we bring to each inspection is informed by decades of seeing how sewer lines actually perform across the region.

After the inspection, your plumber walks through what was observed and what it means. If the line is in good shape, that is what you hear. If issues are developing, you hear that with a realistic sense of timing and what the options look like. No alarm, no upsell.

If the inspection surfaces conditions that warrant cleaning, repair, or replacement, the same licensed plumbers handle the follow-up work. One company, one relationship, from inspection through any follow-through the line may need.

Other Plumbing Services Princeton Air Handles

A sewer inspection often connects to other plumbing services, and the same team handles each of them.

Depending on what the inspection finds, the next step may be a closer look with a camera, a cleaning of the line, a focused repair, or no action at all.

When a sewer inspection warrants a direct visual review of the line’s interior, a camera sewer inspection provides that footage. The camera is the most precise tool for seeing what is actually happening inside the pipe, and it is often the method we use as part of a broader sewer inspection when the situation calls for it.

Many sewer lines benefit from periodic cleaning to remove scale, grease, and minor root intrusion before those accumulations cause larger issues. Our team handles sewer cleaning as both a scheduled service and as a response to specific findings.

For homeowners who want a broader assessment of the home’s plumbing beyond just the sewer line, our licensed plumbers perform whole-home plumbing inspections that cover fixtures, water heaters, shutoff valves, visible plumbing, and drainage across the system.

For blockages or flow issues in specific drains within the home rather than in the main sewer line itself, our team handles drain cleaning and repair as a focused service.


Schedule Your Sewer Inspection

An inspection of the sewer line is one of the clearer home services a homeowner can book for the information it produces.

If the home’s sewer line has not been inspected, or if it has been long enough that the homeowner is not sure of its current condition, our licensed plumbers are ready. Call Princeton Air today to schedule your sewer inspection.

Sewer Inspection FAQs

When should I schedule a sewer inspection?

For most homes, a sewer inspection is worth scheduling every few years, with more frequent review for older homes, homes with a history of sewer issues, or homes where nearby trees have aggressive root systems. A sewer inspection is also a strong idea before buying a home, before a significant landscaping or excavation project, or after any event that might have affected the line.

What does a sewer inspection involve?

The scope depends on the specific line and what the inspection is trying to establish. A typical inspection evaluates the line’s condition, identifies any obvious blockages, root intrusion, scale, or damage, and produces documentation of the findings. Your licensed plumber discusses the appropriate approach with you based on the home and the reason for the inspection.

Is a camera sewer inspection the same as a sewer inspection?

A camera sewer inspection is one common method within the broader category of sewer inspection. A sewer inspection is the overall evaluation of the line’s condition, and camera inspection is one tool that makes that evaluation more precise. Some inspections use a camera throughout, some use it selectively, and some rely on other methods depending on the situation.

What happens if the inspection finds a problem?

You get an honest explanation of what was found and what the realistic options are. Some conditions are addressed with cleaning. Some warrant a focused repair. Some older lines benefit from full replacement. The inspection produces the information; the decision about next steps is the homeowner’s.

How long does a sewer inspection take?

Typically one to two hours, depending on the length of the line, the home’s access points to the sewer, and the condition of what is being reviewed. Inspections that involve camera work or that require establishing access for the first time can take longer. Our plumbers give the inspection the time it deserves.
