"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!"

"We were in a jam. We are attempting to buy our first home. We had our inspection scheduled and on the morning of, we learned of a potential plumbing issue. There was a report filed with the city stating that a couple of years ago there was some kind of sewer back up. This house is old, so I wanted to make sure we weren't signing up for any potential problems. I called around to local plumbers in the area. NONE of them were able to accommodate our need on this shortened time frame. I got Zach's number from a contractor friend of mine and in a last ditch effort gave him a call. Unlike some of the other plumbers I'd spoken with, Zach validated my concerns and informed me that he would recommend that I have my system inspected. He was very patient with my partner and I, making room for us that evening to show up in exemplary fashion. He did a full inspection of our sewer lines with a camera and explained to us what the different piping meant. He then tested our water pressure and advised us to request that the seller offer concessions to cover the cost of putting in a pressure reduction valve. He explained the reasoning behind his recommendations and took time to insure that we understood why he was recommending these services. He also took the time to explain and answer questions about potential upgrades as my partner wants to upgrade the hot water tank. He outlined different product options and explained with great knowledge and detail the differences between the products. I would highly recommend this company. If we get the home we will definitely be having this company come back and preform the necessary work that is needed for our new home."

"I went to Mad Pipers for a second opinion after getting a vague and uninformed assessment of my drain issues from a different company. Ragen and Zach not only took the time to figure out the extent of the problem, but they made sure I understood and knew what my options were, without pressuring me to hire them. I respected both their attention to detail and integrity so decided to hire them for the job. Rather than replace the entire drain system as recommended by another company, they discovered the problem areas where roots were growing into the pipes and were able to replace just the necessary sections effectively and efficiently. This included excavating and trenching the line from a tiny crawl space, redirecting the line to a much more practical location outside the house, adding gravel around the new pipe, reconnecting the line to the unaffected section, and complete and tidy cleanup of my yard, all in two days. I have complete faith in these guys and would definitely hire them again for any future plumbing needs."

"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."

"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."

"Diagnostician/Estimator and Plumbing team were just excellent. Sewer work and team very good, but also very pricey. Repairs on system were well done - crawlspace access area was damaged to extract the old sewage tank. Damage is still being repaired by homeowner. Harts rebated some cost to cover access damage. All Harts team members were fully vaccinated, wore masks, and were great to work with. Harts completed work within 1 day within quoted costs. New sewer pump alarm system system malfunctioned right after the install was finished - Harts sent a repair tech out to fix it on next day - excellent service - fixed the twisted tank float problem - no charge. Building inspector noticed new sump pump was tilted and alarm wiring was not properly affixed to the house - minor issues, I would hire Harts again but negotiate hours and pricing ."

"We put this off longer than we wanted. Ross stayed in touch from time to time and ultimately came in significantly less than most other bids. Bruce (Ross' twin brother) and his crew of two additional laborers showed up at 9AM (on-time) and got straight to work. They politely answered all my ridiculous home-owner questions and finished up at 3PM. It was pretty much just digging, breaking up and removing old pipe, fitting new pipe and replacing the dirt. I had a bump out from the house that caused me great concern. As it turns out, Bruce has a background in general contracting. He stayed far away from the bump out and explained why it wasn't at risk. I'm a Realtor and have seen enough sewer problems that I prepared myself for the worst; however, what I got was the best. The best option for my problem, the best price and the best company. I would not hesitate for a moment to use or recommend Seattle Select LLC."

FAQs for sewer main install, replace or repair projects in Sammamish, 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.
