Pipe Burst & Collapse Repair in Seattle, WA
A burst or collapsed sewer pipe can lead to significant damage and unsanitary conditions. These issues can result from shifting soil, corrosion of old cast iron or clay pipes, or heavy vehicle traffic above the line. FHN Plumbing offers emergency repair services to quickly address these critical failures. We accurately locate the damaged section and provide durable repair or replacement options, often using trenchless methods where appropriate to minimize disruption.

We prioritize these critical issues so your home's plumbing is quickly brought back to safe operating condition, even outside of regular business hours.
Video Camera Sewer Inspection in Seattle
Before any repair, we use high-resolution video camera inspection to accurately locate and assess sewer line damage. This involves inserting a flexible rod with a camera into your sewer line, allowing us to see blockages, cracks, root intrusion or pipe collapses in real time. This non-invasive method prevents unnecessary digging and helps us provide a precise diagnosis and repair plan. It's key for understanding issues in older homes in Seattle and identifying problems like bellied pipes or collapsed sections.
Sewer Camera Inspection in Seattle
Every sewer repair starts with a look inside the pipe. We run a self-leveling camera from your cleanout or a pulled toilet and record the full length of the line. A sonde in the camera head lets us mark the exact location and depth of every problem on the surface. You get a copy of the video and a plain-language summary of what we found. This step alone often saves homeowners from paying for repairs they do not need.
Sewer Line Backups & Blockages in Seattle
Sewer backups are usually caused by severe blockages from grease buildup, foreign objects or heavy tree root intrusion. Our team uses advanced sewer camera inspections to identify the exact cause and location of the blockage. We then use hydro-jetting or mechanical snaking to clear the obstruction, restoring proper flow to your system and preventing further damage. This approach is highly effective for the stubborn clogs often found in older Washington homes.
Root Intrusion Removal in Seattle, WA
Tree roots are a leading cause of sewer line blockages and damage, especially with the mature trees found in many Seattle neighborhoods. Roots can work into tiny cracks, expand and eventually crush or clog pipes. We use specialized augers and hydro-jetting to cut through and remove roots, followed by inspection to assess pipe integrity. For ongoing issues, we may recommend trenchless repair or pipe replacement to prevent future root problems.
Orangeburg and Cast Iron Sewer Replacement in Seattle
Some older homes still have Orangeburg pipe, a tar-paper material that flattens and blisters over time. Cast iron from the same era corrodes from the inside and scales up until little flow remains. When a camera shows widespread failure, patching is a waste of money. We replace the line in sections or end to end with PVC, and we can often use trenchless methods to avoid tearing up the whole yard.

Frequently Asked Questions About Sewer Repair in Seattle
The cost of sewer repair in Seattle, WA can vary widely, typically ranging from $300 for a simple clog removal to $6,000 or more for extensive line replacement using trenchless methods. Factors include the extent of damage, pipe material, accessibility and whether excavation is needed. We provide a detailed estimate after a thorough inspection.
FHN Plumbing stands behind our work with solid warranties on parts and labor for sewer repair services. The warranty period can vary based on the type of repair and materials used, but we always make sure our customers have lasting peace of mind. Details will be provided with your estimate.
Sewer repair is complex and best left to licensed professionals due to the specialized equipment required, potential health hazards and strict local plumbing codes. Attempting DIY repairs can lead to further damage, costly mistakes and even safety risks. Always consult with a professional plumber.
Yes, weather can impact sewer lines. Washington has two very different climates, with long, wet and mild seasons in the west and hot, dry summers and cold winters in the east. Heavy rains can saturate the ground, putting pressure on pipes and widening existing cracks. Dry spells can cause soil to shift, leading to pipe misalignment or breaks.
Common signs include recurring drain clogs, multiple fixtures backing up, foul odors coming from drains or the yard, gurgling noises from toilets, unusually lush patches of grass in your yard or dips in your lawn. If you notice any of these, especially combined with slow drains, it's wise to call for a professional inspection soon.
Most spot repairs are completed in one day, including excavation and backfill. Larger replacements or jobs that need a city right-of-way permit can take two to four days. We give you a timeline before we start.
Standard policies often exclude wear, tear and root damage to the sewer line itself, though they may cover resulting water damage inside the home. Some insurers offer a service line endorsement. We provide video and written documentation if you file a claim.
To prevent future sewer line problems, avoid flushing anything other than toilet paper, dispose of grease properly and be mindful of what goes down your drains. Consider having annual professional drain cleaning or sewer inspections, especially if you have older pipes or mature trees near your sewer line. Regular maintenance can catch small issues before they become major problems.
