Sewer Line Repair & Replacement FAQ
How do I know if my sewer line is damaged or failing?
Common signs include slow drains throughout the home, frequent backups, gurgling sounds, foul odors, or water pooling outside. Many older homes in West Seattle have aging sewer lines that can fail over time. A camera inspection is the best way to confirm the condition.
Do I need a sewer repair or full replacement?
It depends on the condition of the pipe. Minor issues may be repaired, but older or heavily damaged sewer lines often require full replacement to prevent ongoing problems. We’ll inspect the line and recommend the most reliable long-term solution.
Do you offer sewer camera inspections?
Yes. We perform sewer camera inspections to locate blockages, breaks, root intrusion, and other issues. This allows us to accurately diagnose the problem before recommending any work.
How much does sewer line repair or replacement cost?
Sewer work can vary significantly depending on the depth of the line, access, and overall condition of the pipe.
• Sewer camera inspections are typically $500
• Spot repairs can range from $3,000 to $5,000 in the Seattle area
• Trenchless sewer replacements may range from $8,000 to $10,000 depending on complexity
• Full sewer line replacements typically range from $8,000 to $15,000 or more depending on depth, access, and site conditions
We provide a clear evaluation after inspection so you understand the exact scope and cost before any work begins.
Can sewer repairs be done without digging?
In some cases, trenchless methods may be an option depending on the condition of the pipe and layout. Not all sewer lines qualify, but we can evaluate and explain the best approach for your situation.
How long does sewer work take?
Most sewer repair or replacement projects take one to several days depending on the scope of work, access, and site conditions.
Will my yard or driveway be affected?
Traditional sewer replacement may require excavation, which can impact landscaping or hard surfaces. We take care to minimize disruption and restore areas as cleanly as possible.
Do you work on side sewers?
Yes. We repair and replace side sewer lines connecting your home to the city main and can help identify issues within that system.
Can tree roots damage my sewer line?
Yes. Root intrusion is one of the most common causes of sewer line failure, especially in older Seattle homes. Roots can enter through joints or cracks and cause blockages or pipe damage.
What type of pipe do you install for sewer replacement?
We install durable, code-approved piping such as PVC designed for long-term performance and reliability.

Yes. If you’re experiencing a backup or urgent issue, contact us and we’ll help determine the fastest way to address the problem.
