Sewer Cleanout

The Easy Door Into Your Sewer Line

Why Your Line Needs a Way In

A sewer cleanout is the capped pipe that lets a technician reach your sewer line straight from the yard. Without one, clearing a clog means pulling a toilet or working down a roof vent, which turns a simple job into a bigger, messier one. If your Seattle home was built before cleanouts were standard, or someone paved over the one you had, a sewer cleanout is the fix that makes every visit after it faster and cheaper.

Aces Four has installed and repaired cleanouts across Seattle since 1978. We are family-owned, licensed, insured, and bonded, and as a drainage and sewer contractor, exterior cleanout work on the line is squarely our trade. We run our own excavation crew instead of handing your yard to a subcontractor, so one team finds the line, sets the fitting, pulls any permit the job needs, and puts the ground back.

No Hatch, No Easy Fix

Reasons Homeowners Finally Add One

Most people never think about a cleanout until a backup forces the issue. These are the situations that bring the call:

✓No Cleanout Anywhere on the Property
A plumber has to reach the line through the house itself. Every clog becomes a bigger job than it should be.

✓The Cleanout Is Buried
Landscaping, a patio, or a concrete pour covered it. It exists, but no one can reach it when the line backs up.

✓The Cap Is Broken or Cemented Shut
A cracked or stuck cap lets in dirt and roots and defeats the access. A fresh cap restores a clean, sealed entry.

✓A Backup Keeps Returning
If the line clogs on a schedule, an accessible cleanout makes each clearing quicker and gives us a camera port to find the cause.

✓The Riser Sits Below Grade
A cleanout that ends underground fills with mud and standing water. Raising it to the surface keeps it dry and usable.

✓The City or an Inspection Requires One
Some code requirements and permit conditions call for an accessible cleanout. Adding one keeps the property compliant.

✓A Home Sale Flagged It
Inspectors and buyers note a missing or buried cleanout. Installing one clears the report before it stalls a closing.

Backed up right now and no way to reach the line? Our emergency sewer service can add an accessible cleanout as part of clearing the line, after hours or on a weekend when it can't wait.

Not sure whether you already have one? We locate the line first and confirm whether a cleanout exists before we scope the work.

Find It Before the Shovel Moves

How We Locate the Line

Half the work is knowing where the sewer runs before anyone digs. Guess wrong and you get a bigger hole and a bigger bill, so we find the line first, then choose where it goes.

Site walk and camera. We start with a visual search, then send a camera down the line and track the sonde from the surface to trace the exact path.
Electronic locating and depth marking. A locator maps the pipe across the yard with no trial holes, and we flag how deep it sits so we know the dig size and riser length up front.
City records check. Where they exist, we pull side-sewer records and as-builts to establish line direction and slope before we commit.
811 utility locate. Before any excavation we call in the public locate so gas, power, and water lines are marked and avoided.
Written summary with photos. You get a record of what we found and where, not just a verbal rundown.

Once the line is mapped, we confirm the plan and show you the spot before we open the ground. For a full look inside the pipe, our sewer camera inspection uses the same gear to check condition and slope.

From Locate to Clean Lid

What a Sewer Cleanout Install Covers

A sewer cleanout installation is a single focused job, and many run start to finish in a day. Here is the shape of it:

Locate and mark the line, agree the placement with you, clear the 811 locate.
Excavate a narrow access hole down to the pipe, hand-digging near marked utilities and roots.
Cut into the line, fit the cleanout tee, and set the riser to grade.
Add the box, cap, and lid, plus a backwater valve if you want one.
Run a flow test and a camera check to confirm it seats and drains.
Backfill, compact, restore the surface, then show you how to open and use it.

What stretches a job is the locating, not the fitting. If the line sits deep or hides, finding it takes the time. Financing is available through GreenSky if you would rather spread the cost.

One Access Point or Two

Cleanouts come in a few configurations, and the right one depends on your line and how you expect to use it:

One-way reaches the line from a single direction. Simple and low-profile, common on short runs.
Two-way opens both directions from one spot, toward the house and toward the main. A two-way cleanout near the property line is common on longer runs, and many local jurisdictions want one point near the building and another out toward the city main.
At-grade with box and lid finishes flush with the lawn or driveway and takes foot or vehicle traffic.
With a backwater valve lets waste out and blocks it from flowing back in, for properties prone to main-line backups.

We tell you the least you can install and still solve the problem, not the most we can sell.

Fixing a Cleanout That Stopped Working

Not every call is a new install. Plenty are cleanouts that used to work and quit. Sewer cleanout repair covers the common failures:

A broken sewer cleanout cap. Cracked, missing, or cemented shut, it lets in grit and roots. We fit one that seals and opens cleanly.
A crushed or offset riser. Soil movement or a passing vehicle can collapse the riser above the line. We dig it out and replace the damaged section.
A cleanout lost under new surface. Landscaping or a concrete pour swallowed it. We locate it, expose it, and raise it back to grade so it is usable again.

If the pipe itself is failing rather than the fitting, that is a different job, covered on our sewer pipe replacement page.

The Crew and Gear That Show Up

A cleanout is small compared to a full dig, but it still takes the right equipment to do it clean and safe:

Mini-excavator for a tight, controlled access hole, with hand-digging near marked utilities and roots.
Concrete saw and core drill for cutting through a driveway, slab, or patio over the line.
Camera, sonde, and locator to map the line going in and verify the fitting going out.
Compaction and pipe-fitting tools to backfill solid and seat the connection right.

We run the core of every job in-house, so the crew that locates your line is the one that fits the cleanout and restores the ground. Every dig starts with a utility locate, and we contain and haul off the spoils rather than leaving a pile behind.

Permits and Inspections, Handled

Some cleanout jobs need a permit and a city inspection, and the rules shift from one jurisdiction to the next across the Seattle area. We handle that side end to end:

The permit application where the work requires one.
811 utility locates before we dig.
Right-of-way or street-opening permits if the access point falls near the roadway.
Scheduling the city inspection and meeting the inspector on site.

You get a clean, compliant cleanout and the paperwork to prove it, without spending your week on the phone with a permit office.

We locate before we dig

The worst job is one that tears up a yard because no one found the line first. We trace and mark the pipe, then dig one small opening in the right place.



One in-house crew, front to back

The people who find your line fit the cleanout and fill the hole. Nothing is lost in a handoff to a subcontractor.



Small hole, full restoration

We dig only what the access point needs and put the surface back, lawn, gravel, or concrete. No scar left for you to fix.

We stand behind the work

If something isn't right with the cleanout we installed, we come back and fix it. No claim forms, no third party, the same crew that did the work handles it.

What is a sewer cleanout?

A capped access point on your sewer line, usually a short vertical pipe in the yard, that lets a technician clear, camera, or jet the line. Without one, reaching the line means going through a fixture or a roof vent, which costs more and takes longer.

How do I find my sewer cleanout?

Look for a capped pipe a few inches across near the house, along the path to the street, or in a basement or crawlspace. On older Seattle homes it may be buried under landscaping. If you cannot find one, we locate the line and tell you whether a cleanout exists at all.

What if my house has no cleanout?

Plenty of older homes were built without one. We locate the line, pick the best spot with you, and install a cleanout so future service is simple. It is one of the most useful upgrades an older sewer line can get.

What does a sewer cleanout cost?

There is no flat price. Depth, distance from the house, the surface over the dig, whether the line needs locating first, and a one-way versus two-way setup all move the number. We scope the job and give you a written estimate at no charge rather than posting a guess.

Do I need a permit for a cleanout?

Sometimes, depending on the work and the jurisdiction. When a permit or inspection applies, we handle the application, the locates, and the inspection as part of the job, so you are not sorting it out yourself.

Do you guarantee the work?

Yes. We guarantee our workmanship and will come back and fix any issue with a cleanout we installed.

Can you add a cleanout during other sewer work?

Often, yes. If we are already on site for a repair, lining, or cleaning, adding a cleanout at the same time usually costs less than a separate trip.
