Pro Services installed a 6 inch clean out and placed a lateral liner in our sewer line. What can I say, they did and excellent and professional job from start to finish. They're a great company.

After what started off as a horrible day we had plumbing issues on top of it. Cody came in and fixed it without hesitation and had the best attitude. I know it’s something small but he was a breath of fresh air. Thank you

Cody is the greatest person I have ever encountered!!! I was panicked about a sump pump issue and he contacted me right away and assured me all would be OK. He was prompt, knowledgeable and friendly.

Sags, low spots & standing water

Tell us what keeps happening.
We'll show you why.

A belly doesn’t announce itself. It shows up as the same clog, in the same stretch of pipe, a few months apart — and it doesn’t get better on its own.

Second opinions welcome

“Another plumber told me I have a belly.”

A belly is a section of pipe that has settled below grade, so waste sits in it instead of running out. Whether that matters depends on how much of the pipe the standing water fills. We re-camera the line, locate the low spot, and measure it — then tell you whether it’s a maintenance job or a dig.

Before we start

“It clogs in the same spot every few months.”

Rodding punches through and the house works again — then it fills back in. When the same stretch of pipe clogs on a schedule, the pipe usually isn’t the problem. The grade is. Standing water in a sag collects grease and paper until it closes up again.

“The sewer scope came back with a sag.”

Inspection reports rarely say how bad. We re-run the line, locate the low spot to the foot, and measure how much of the pipe it actually holds — so you can price the repair or negotiate it with footage to back you up.

 

How it works

We don't recommend a dig
until we've measured the sag.

You can’t see a belly from inside the house. So we put it on a screen, mark it on the ground, and let you decide from there.

  1. An expert picks up.

    Describe what keeps happening, or read us what the last camera report said. We'll tell you whether this needs a truck today or an inspection next week — even if the honest answer is that it can wait.

  2. We camera the line and find the low spot.

    You watch the screen with us. Standing water sitting in pipe that should be running clear is the belly — and we locate it from the surface, so you know exactly where it sits and how deep before anyone quotes a repair.

  3. You get the options in writing.

    Jet it and monitor it, spot-repair the sagging section, or replace the run — each with a price and how long it buys you. If maintenance will hold it for now, that's on the list too. The number doesn't move once you've signed it.

  4. We re-camera it when we're done.

    Same camera, same line. You watch the water run out instead of pooling, and you keep the footage. If it's still holding water, we haven't finished.

Not sure yours needs fixing yet?

Call and ask. We’d rather talk you out of a repair than sell you one you didn’t need.

our customer service.

Whether it’s a backup at midnight or a sag you’ve been putting off, you get the same straight answer and the same upfront price. 

DIAGNOSIS

We measure the sag before we price it

A camera goes down the line, the low spot gets located from the surface, and we measure how much of the pipe is actually holding water. You watch the screen with us.

STRAIGHT TALK

Sometimes the answer is to leave it alone

A shallow belly can run for years on jetting alone. When that’s what yours is, we say so — we’d rather lose the job than sell you an excavation you didn’t need.

We’ll tell you when it can wait 

PRICING

The number doesn’t move

Quoted in writing before we start, and it holds once the ground is open.

YOUR YARD

We dig where it sags

The low spot is marked from the surface first, so it’s a small opening — not a trench across the lawn.

Concrete and restoration quoted up front 

PAPERWORK

You keep the video

Footage and a written report — what insurers and real estate attorneys ask for.

The questions
you might be asking

What does fixing a belly actually cost?

Depends on how deep the sag is, how far down the line it sits, and what’s sitting on top of it — which is why we camera and locate it before quoting. The honest ranges:

Camera inspection & locate (free with service)

$XXX – $XXX

Hydro jetting, main line

$XXX – $XXX

Spot repair, sagging section

$XXX – $XXX

Full line replacement, per foot

$XXX – $XXX

The pipe itself is usually fine — the ground underneath it moved. Poor bedding or loose backfill at the time of install is the most common cause; the pipe settles into it over the years. Soil that shifts with the water table, freeze-thaw cycles, heavy loads driven over the line, and nearby excavation all do the same thing. Older clay and cast lines show it more often simply because the ground has had longer to give.

The measure that matters is how much of the pipe the standing water fills. A shallow belly — one holding roughly a third of the diameter or less — often behaves for years with jetting on a schedule, and we’ll tell you when that’s the case. Once the water fills more of the pipe than that, or the clogs start arriving faster than maintenance can stay ahead of, you’re paying repeatedly for something a repair would end. We’ll show you the footage and tell you which side of that line you’re on.

Usually not, and anyone who tells you it will is worth a second opinion. A liner rebuilds the inside of the pipe and follows whatever shape the pipe is already in — including the dip. It’s the right tool for cracks, roots and deteriorated clay. It doesn’t lift a sagged run back to grade. Correcting grade means re-bedding the pipe, and that means opening that section of ground.

Only over the sag, and only if it needs it. We locate the low spot from the surface before anything is opened, so the dig is a marked area rather than an exploratory trench — usually a few feet of it, not the whole run. If the belly sits under a driveway, patio or finished slab, we price the concrete work up front with everything else, so it isn’t discovered halfway through.

Get it re-scoped by a plumber rather than working off the inspection summary. “Belly noted” and a located, measured sag are two different pieces of information, and only one of them has a number attached to it. We’ll run the line, mark the low spot, and put the repair cost in writing — that’s the document that moves a negotiation, whichever side of the table you’re on. We work around closing timelines.

Usually not for the pipe itself. Standard policies typically exclude damage from settling, wear and normal deterioration — which is exactly what a belly is. What some policies do cover is the water damage caused by a backup, and many insurers sell a separate sewer backup rider for a modest annual cost. We’re plumbers, not adjusters, so call your carrier for a real answer. What we can do is give you a written report and camera footage documenting the failure, which is what they’ll ask for.

Still not sure how bad yours is?

Read us the camera report, or just describe what keeps happening. We’ll tell you what it probably is and what it’d cost — before anyone gets in a truck.
