"This sewer line project required a few days from camera work to excavation, replacement of pipe, installation of an additional clean-out, backfill and clean up of not only our excavation area, but consideration of our neighbor's shrub close to the work area. Chris and Ryne, the company supervisors/representatives, provided knowledgable and detailed information prior to, during and upon completion of the work. They were professional and exceptionally courteous in person, to our neighbors, and over the phone. This was especially important as one of us was out of state during the project, and the other had to leave early for another trip out of state. That meant the final inspections and details were handled by the guys for us. Excellent work, start to finish!"

"Donnie came all the way to Kent late. We had a water line break that flooded out front yard and our crawl spaces. Our sump pump had quit working. He gave us a quote well under others and they were here the next day. They ran into several other issues as well. Donnie said it was the most difficult repair he had ever run across, but they got the job done and we couldn't have been happier. He even helped us figure out the on line financing and never complained. We would highly recommend Jet City Plumbing and have already told others with plumbing problems, to get in touch with them. You will not go wrong. If we have other issues with our old home, we will be sure to call them for help Thanks guys, you're the best!! J & F June Kent, WA."

"David and team replaced a section of my sewer line and added a liner. I talked to 3 other companies and chose David due to his diagnostic review of my issue, competitive bid, and professionalism during the estimate bid process. David was communicative and friendly through the entire repair process. He showed up when he said he would and worked efficiently. He was always conscious of the quality of his work and how he left the area each day. He walked me through what he did and was clear about what he was doing and why. Highly recommended for all your sewer needs!"

"Jerry was very enjoyable and professional in replacing a bent lead toilet connection which had leaked at the toilet. He replaced the old lead connection to the cast iron sewer pipe with modern ABS pipe and installed a flange to attach the new toilet to when the floor is completed."

"What I thought was a simple clogged shower drain turned into much more after having Pipers Drain come out and access the problem. Patrick came out on a Sunday and found out that tree roots had clogged and damaged my pipe that took the waste water to the sewer. He explained the whole process to repair the pipe and also check the rest of my pipes with his camera. His team came out the next week to excavate part of the driveway to reach the broken pipe. The workers arrived on time, were considerate and cleaned up the area before they left. Patrick returned to view the rest of the pipes and found that some of them had channel rot from tree roots which compromised the pipes. Luckily, the damaged pipes were salvageable and a liner was installed in about 25 feet of pipe. Patrick kept in constant communication with me every step of the way and responded quickly whenever I had questions. I’m very happy with the repair and highly recommend Patrick and his team."

FAQs for sewer main install, replace or repair projects in Seattle, WA

Most trenchless sewer line replacements can be completed within one to three days, though this varies based on your situation. Simple repairs on accessible lines might be finished in hours, while complex systems or challenging soil conditions could extend the timeline. The reduced excavation requirements result in faster completion compared to traditional trenching methods.

Trenchless pipe lining may reduce the interior diameter of your pipes, which could affect flow capacity in already narrow lines. This method also requires the existing pipe to maintain sufficient structural integrity to support the new liner. Severely collapsed sections, major joint separations, or completely misaligned pipes might not be suitable candidates for lining and could require alternative approaches.

Trenchless sewer pipe liners are rated to last up to 50 years when properly installed and maintained. Actual longevity depends on installation quality, usage patterns, and environmental factors like soil movement or tree root intrusion. Regular maintenance and avoiding problematic disposal practices (like flushing non-biodegradable items) can help maximize your system's operational lifespan.

Trenchless technology availability varies by region, with greater accessibility in metropolitan and suburban areas where specialized contractors operate. Some rural locations may have limited access to trenchless equipment and expertise. Local regulations and soil conditions also influence availability. A professional assessment of your property and local contractor options will determine if trenchless methods are feasible for your specific location.

Professional video inspection provides the most reliable assessment of whether your sewer issues suit trenchless repair. Generally, pipes with moderate damage, like small cracks, minor leaks, or partial blockages, respond well to trenchless techniques. Completely collapsed sections, severe misalignments, or extensive structural failures might require traditional excavation. Consulting with contractors who offer both methods ensures you receive unbiased recommendations.

Quality trenchless sewer replacement often includes a workmanship guarantee from the contractor. The specific terms vary by company and region, but many professionals stand behind their installation for at least one year. Material warranties may extend longer, depending on the pipe products used. Always request written warranty information before hiring, and understand exactly what's covered and what might void your protection.
