What our sewer line replacement includes
Every sewer line replacement we do starts with a camera inspection and ends with video proof the new line is clean.
Work order
Sewer Line Replacement- Full camera inspection: We run a RIDGID SeeSnake camera the full length of the lateral and record it. You watch the screen with us and see every crack, root, and offset before we quote a price.
- Written scope and firm price: The scope names pipe material, diameter, length, depth, and method. The price is firm and in writing. If a spot repair would honestly solve it, we say so instead of upselling a full replacement.
- Permits and utility locates: We pull the City of Longview right-of-way permit and call 811 for locates. Gas, water, power, and fiber get flagged before excavation, which protects you and your neighbors.
- New pipe and proper bedding: We install new PVC or ABS pipe bedded in compacted gravel at the correct 1/4 inch per foot minimum slope. No reusing old fittings, no shortcuts on grade.
- Surface restoration: Backfill goes in lifts, gets compacted, and the surface is restored. Plywood protects the lawn during the job, and we magnet-sweep for nails and screws at the end.
- Final camera pass and footage: We camera the finished line and hand you the video. You see clean pipe, correct slope, and no roots. The job is not done until the footage proves it.

Sewer Line Replacement longview WA explained
A sewer line is the one pipe you cannot see and cannot afford to guess about. We camera it, show you the problem, and replace it so waste moves downhill the way it should. Then we camera it again to prove the job is done.
Sewer line replacement longview WA is the full excavation or trenchless swap of the private lateral running from your home or business to the city main. We cut out the failed section, or the entire run, and install new PVC pipe, pipe fittings, and properly bedded gravel. A drain snake or auger only buys time on a collapsed line. Replacement fixes the actual pipe, so waste moves downhill the way the code intends.
Most Longview laterals we open are 40 to 80 years old. Cast iron cracks, Orangeburg crushes, and clay tile joints separate. Add our wet winters, heavy clay, and the willow and cottonwood roots that chase moisture, and you get root intrusion, repeat clogs, and sewage backing into a basement floor drain. If you have been searching for sewer line replacement in longview WA near me after a third snaking, that is usually the signal to stop patching and replace.
- What it is
- Full swap of the private lateral from building to city main.
- When it helps
- Repeat backups, collapsed pipe, root intrusion, offset joints.
- What you get

When Longview homeowners replace a sewer line
A 1948 bungalow near Downtown Longview has backed up three times in two years, and snaking only buys a few months.
We camera the lateral, find the root mass and offset joints, and quote a trenchless pull through the existing alignment.
HomesA rental in North Longview has sewage backing into the basement floor drain, and tenants are threatening to leave.
We respond the same day, stop the backup, and camera the line. The scope shows a collapsed section under the front yard.

How sewer replacement runs in Longview
Longview sits on heavy clay soil that swells in our wet winters and shrinks in dry summers, and that movement is hard on buried pipe. Laterals from the 1940s and 1950s are usually clay tile or cast iron, both of which crack and offset over decades.
Downtown Longview
Older commercial and residential blocks with clay tile laterals and tight right-of-way access. Trenchless pulls are often the only practical option here.
Longview Heights
Mid-century homes on sloped lots where grade and soil movement cause offset joints. We laser-check fall on every replacement.
North Longview
A mix of 1950s ranches and newer builds. Cast iron and clay tile are common, and roots from mature street trees are a frequent culprit.

PhotoTrenchless pull saves a Downtown driveway
Before: A 1948 bungalow near Downtown Longview had clay tile laterals with root intrusion at four joints and a belly holding water. The driveway sat directly over the line, and the homeowner did not want it torn out.
After: We pulled new HDPE through the old alignment from two access pits, disturbing about 10 square feet of ground instead of 300. The finished camera pass showed clean pipe at correct slope. The driveway was untouched.
Collapsed cast iron replaced in North Longview
Before: A 1955 ranch had sewage backing into the basement floor drain. The camera showed a collapsed cast iron section under the front yard and heavy scale buildup through the rest of the run.
After: We excavated the failed section, replaced the full lateral with PVC bedded in compacted gravel at 1/4 inch per foot, and restored the yard. Three days total. The final camera pass showed clean flow end to end.
Commercial grease line rebuilt on Commerce
Before: A restaurant off Commerce Avenue had a grease-bound lateral that clogged monthly despite regular jetting. The camera showed a belly holding water and grease-packed pipe through a 40-foot section.
After: We replaced the run with correctly sloped PVC sized for the actual kitchen load and scheduled the work around open hours. Monthly emergency calls stopped. The restaurant now runs a normal quarterly cleaning schedule.
Roots invading clay tile joints
Roots grow into the joint gaps, catch paper and grease, and cause repeat backups every few months. Snaking cuts roots but leaves them alive to regrow.
Collapsed or crushed pipe
A collapsed section blocks flow completely. Sewage backs into the lowest drain in the house, often a basement floor drain or laundry standpipe.
Bellied line holding water
A sag in the pipe traps water and debris. The line drains slowly, smells, and clogs constantly because waste never fully clears the low spot.
Orangeburg or failing cast iron
Orangeburg pipe deforms and collapses with age. Cast iron cracks and scales shut from the inside. Both fail without warning and cannot be reliably patched.
Offset joints from soil movement
Longview's clay soil shifts with wet winters and dry summers, pushing pipe sections out of alignment.
Why replace instead of patch
A repaired pipe fails again. A replaced pipe is new from end to end, sized correctly, and bedded so Longview's soil movement does not crack it.
No more repeat backups
Root intrusion returns within one or two seasons when roots are only cut, not removed with the pipe.
Trenchless saves the yard
Trenchless sewer replacement longview pulls new pipe through the old line from two small access pits instead of a 60-foot trench.
Correct slope, correct code
Sewer must fall at a minimum 1/4 inch per foot. Old Longview lines often sag, bellies, or were pitched wrong from the start.
Higher resale value
A documented sewer replacement is a selling point in Cowlitz County. Buyers ask for the camera footage and the receipt.

What Longview customers say
Third backup in 18 months and I was done snaking it. They cameraed the line, showed me a root mass the size of a basketball at the 32-foot mark, and quoted a trenchless pull. Two days later the new pipe was in and the driveway was untouched. Camera footage at the end showed clean pipe. Worth every dollar.
Our 1952 house had clay tile that was offset at three joints. They explained the whole thing on the screen, gave me a written price, and stuck to it. The crew laid plywood over the lawn and swept for nails before they left. No backups since, and that was last winter.
We manage six rentals and one had sewage backing into the basement. Longview Riverbend handled the emergency, then scheduled the full replacement the following week. They pulled the city permit, kept the tenants informed, and finished in three days. I have used them on two more properties since.

(360) 886-3111Length, depth, pipe material, and whether the city sidewalk or street has to be cut are the big swing factors. We camera first, then quote a firm number in writing.
Replace when the camera shows collapsed pipe, offset joints, a belly holding water, or root intrusion that returns within a season. Three or more clogs in two years is the classic signal. If your lateral is Orangeburg or 1950s clay tile, plan the replacement before it fails, not after sewage backs into your basement on a Sunday.
Yes. We pull or burst new HDPE or PVC through the existing alignment from two small access pits, which protects driveways, patios, and root systems. Trenchless works when the old pipe still has enough structure to guide the new line. If the camera shows a fully collapsed run, we tell you and trench instead.
A typical 50-foot residential lateral takes one to three working days, including excavation, pipe installation, backfill, and the final camera pass. Trenchless pulls often finish in one or two days. Longer runs, deep lines, or city right-of-way work can stretch to four or five days. We give you a day-by-day schedule before we start.
