Sewer Repair & Inspections in Sammamish, WA
Trenchless lining, camera-first diagnosis, and straight answers since 2005
Sammamish sits on a plateau that grew fast, and that growth left a patchwork underground. Some streets tie into municipal sewer through Sammamish Plateau Water and Sewer District, while plenty of older lots on the east side still run on a private septic system. Either way, when a line backs up or a septic-to-sewer conversion goes sideways, Seattle Select Sewers sends a team that has spent two decades working nothing but sewer systems across the Eastside.
We do not guess at what is wrong underground. A camera goes down the line first, so you see the actual problem before anyone talks about a repair path. From there, most jobs get fixed with trenchless lining that leaves your landscaping alone, not a trench across the yard.
Whether it is a slow drain on Sahalee Way or a persistent backup near Pine Lake, Sammamish homeowners get the same straight answer and a written estimate before any work begins.
A plateau still catching up to its own growth
Mixed sewer and septic infrastructure, heavy tree cover, and clay-rich soil
Sammamish only incorporated in 1999, and its utility footprint reflects that patchwork history. Neighborhoods closer to the plateau’s core run on municipal sewer, while a meaningful share of properties, especially on larger wooded lots near Pine Lake and the eastern edge of the Plateau, are still on private systems. We see both regularly, and we handle the conversion work when a septic system finally gives way to a sewer connection.
The tree cover that makes Sammamish desirable is also what stresses sewer lines here. Mature cedars and firs send roots toward any source of moisture and nutrients, and an aging clay or cast iron line is exactly that. Root intrusion is the single most common failure mode we diagnose on the Plateau, and it rarely announces itself until a drain backs up during a holiday dinner.
Homeowners here call us for camera inspections before buying or selling a home, root removal on lines running under mature landscaping, and full trenchless lining when a line has deteriorated past a simple clean-out. For the rare case where lining is not the right fit, we also handle full-line replacement as a last resort.
Where we are: Sammamish, Redmond, Issaquah, Bellevue, and communities throughout the Eastside and greater Puget Sound region.

Why Homeowners Choose Us
Camera-first diagnosis, trenchless-first repairs
Honest timelines, no unnecessary work Nobody budgets for a sewer backup, and a plateau community full of mature trees and mixed infrastructure sees more than its share of surprise root intrusion and line failures. We built our approach around one idea: tell the homeowner exactly what is wrong before recommending anything, and never sell a repair that is not necessary.
Sewer-only specialists
No HVAC, no general plumbing, no landscaping crews. Every technician on our team has spent years working exclusively on sewer systems in the Puget Sound area
Camera inspection before any repair talk
You get a documented look at your line's actual condition before we ever discuss a fix.
Trenchless-first approach
Full sewer replacement is rarely the answer. Cure-in-place-pipe lining restores a damaged line from the inside and can add 40 or more years of service life.
Written estimates, not vague ranges
You get a clear estimate before work starts, walked through in person.
Realistic timelines
Most repairs wrap up in a single day, and we tell you that upfront instead of hedging with "it depends."
Fully licensed and bonded
Licensed and bonded with Washington State Labor & Industries, carrying full liability coverage on every job.
Homeowners who call us once for a Highlands inspection or an Olde Town repair tend to call us again, because the answer we give the first time turns out to be the right one. When the issue turns out to be root intrusion rather than a structural failure, we clear it and confirm the line’s condition on camera before calling the job done, and when it is a single failed joint rather than a full-length problem, a targeted patch is often faster and less costly than relining the entire run.
What We Do
A Full Range of Sewer Services
From routine maintenance to full trenchless rehabilitation
General Sewer Maintenance
A line that gets checked and cleared on a schedule rarely turns into an emergency call. Our general sewer maintenance service covers the routine upkeep that keeps a Sammamish line flowing year-round, especially on wooded lots where root pressure builds steadily rather than all at once.
Trenchless Sewer Repair
When a camera inspection turns up a genuine problem, trenchless sewer repair is almost always the better path on a wooded Sammamish lot. Cure-in-place-pipe lining creates a new, seamless pipe inside the old one without tearing up mature landscaping or a driveway. Most residential jobs finish in a couple of days while keeping the sewer in service.
Sewer Camera Inspections
Root intrusion, pipe pitch problems, and joint separation all hide underground until a backup forces the issue. Our sewer inspections and locating service runs a high-definition camera through the line so you get a clear picture of the exact condition and location of any damage. This is also the service most Sammamish real estate transactions call for, since a sewer scope report gives buyers and sellers a documented, defensible look at the line before closing.
Sewer Line Replacement
When pipes are severely damaged or deteriorated, sewer line replacement provides a long-term solution to restore proper drainage and reliability.
Sewer Pipe Replacement
When a line has deteriorated past what lining or patching can fix, full sewer line replacement remains an option. We treat it as the exception rather than the rule, and only after a camera confirms there is no less invasive path.
Sewer Pipe Patches
Not every problem needs a full liner. For a localized crack or a single failed joint, sewer pipe patches fix the specific weak point without the cost of relining the entire run. We only recommend a patch when the rest of the line checks out clean on camera.
Sewer Cleanout Installation
Older homes on the Plateau sometimes have no accessible cleanout at all, which turns a routine service call into a harder job than it needs to be. We install proper cleanout access so future maintenance is faster and less invasive.
Clogged Sewer Repair
A clog that keeps coming back is rarely just a clog. Our clogged sewer repair service clears the immediate blockage and checks for the underlying cause, whether that is grease buildup, a sagging section of pipe, or roots working their way in.
Sewer Root Removal
Sammamish's mature tree canopy is beautiful and expensive to the sewer line underneath it. Sewer root removal clears roots that have worked into joints and cracks, and we always pair it with a camera check afterward, since a line bad enough to grow roots inside it is often a candidate for lining before the problem returns.
Hydro Jetting Services
Grease, scale, and years of buildup narrow a pipe's usable diameter long before anyone notices a slowdown. Hydro jetting clears that buildup with high-pressure water instead of chemicals, restoring full flow without wearing on an aging pipe wall the way repeated chemical treatments can.
Inspections for Home Builders
New construction on the Plateau still needs a verified, code-compliant sewer connection before anyone signs off. Our inspections for home builders service gives builders and developers a documented camera pass on new lateral runs.
Inspections for Home Buyers
Buying an older Sammamish property sight-unseen underground is a real risk. Our inspections for home buyers service gives buyers, sellers, and their agents a clear picture of the line's condition before closing.
Water Line Installation
A failing or undersized water line is a different problem than a sewer line, but it runs through the same trenches and often gets diagnosed on the same visit. We handle water line installation for properties that need a new or upgraded supply line.
Septic-to-Sewer Conversion
As Sammamish continues to extend municipal sewer service into previously septic-only areas, septic-to-sewer conversion becomes a real project for a growing number of homeowners. We handle the tie-in properly the first time, since a botched connection point is one of the more common and costly mistakes we get called to fix later.
Robotic Cutting Inside Pipes (IMS Machine)
Some obstructions, like an intruding tap or a collapsed section, cannot be cleared with a jetter or a snake. Our robotic cutting service uses an IMS machine to cut and clear obstructions from inside the pipe without excavation.

FAQ
Frequently Asked Questions About Sewer Repair in Issaquah
Is my Sammamish property on municipal sewer or septic?
It depends on where you are on the Plateau. Many neighborhoods closer to the developed core run on municipal sewer through the local water and sewer district, while a number of larger, older lots, especially near Pine Lake and the eastern edge of the Plateau, still rely on private septic systems.
If you are not sure which applies to your property, call us and we can help you sort that out, along with whether a septic-to-sewer conversion makes sense for your situation.
Why do Sammamish homes see so much root intrusion?
The mature tree canopy that defines the Plateau is the same reason root intrusion is the most common sewer problem we diagnose here. Cedars and firs send roots toward any source of consistent moisture, and an aging clay or cast iron line qualifies.
Once roots find a joint or a hairline crack, they widen it over time, which is why a line with visible root intrusion on camera often needs more than a simple mechanical clearing.
Can you fix a sewer line without digging up my yard?
In most cases, yes. Trenchless lining creates a new pipe inside the damaged one using existing access points, which matters on a Sammamish lot with mature landscaping or a driveway you do not want torn up.
A camera inspection always comes first, since confirming exactly what is wrong underground determines whether lining, a patch, or full replacement actually fits the specific line.
How long does a sewer camera inspection take?
Most residential camera inspections on the Plateau take under an hour, and you get a clear picture of the line’s condition and any problem areas before we discuss next steps.
This is also the same inspection many Sammamish real estate transactions request, since a documented sewer scope gives both buyer and seller a defensible record of the line’s condition.
What does a septic-to-sewer conversion involve?
The conversion connects your existing plumbing to the municipal sewer line running past your property, which requires a properly sized tie-in and compliance with local utility and county requirements.
We handle that connection point directly, since an improperly done tie-in is one of the more common and expensive problems we get called out to correct after the fact.
Do you offer a warranty on repairs?
Yes. A 20-year warranty backs most of our trenchless and lining work, and we spell out the specific coverage in writing before anyone picks up a tool.
Are you licensed to work in Sammamish and the greater Eastside?
Yes. We are fully licensed and bonded with Washington State Labor & Industries and carry full liability coverage on every job, including work throughout Sammamish, Redmond, Issaquah, and the surrounding Eastside communities.
That licensing covers every service we perform, from routine camera inspections to full trenchless rehabilitation.
Why Local Homeowners Choose Professional Sewer Repair
Sewer systems in Sammamish can be affected by tree root intrusion, shifting hillside soil, and aging pipe in the city's older neighborhoods, all of which can lead to blockages and structural damage over time if left unaddressed.

By using modern techniques like trenchless sewer repair, hydro jetting, and sewer camera inspections, Sammamish homeowners can restore proper sewer function while reducing the need for extensive excavation. Reliable sewer service protects both the plumbing system and the property above it from unexpected, costly failures.
