"I called Rescue Rooter to come out and clear out a blockage in my sewer line. Chad and Albert came out quickly and got to work. They also put a camera down into the sewer line and had me watch as they went through the line. I saw the various problems in our one hundred year old sewer line. They spent a good deal of time examining the sewer line and also identifying the spot where it becomes a shared line with our neighbor. They presented a number of options of how to repair the deteriorating sewer line along with the different prices for that work. Chad and Albert both explained the different options clearly to my wife and I. They were very friendly and professional."

"Drain Pro plumbing installed a new Toto flush mount toilet for us which requires a bit more work and effort than standard toilet installations. The technician was extremely knowledgeable, professional, and friendly. They have done other projects for us in the past such as convert a single vanity in the master to a dual vanity and redo plumbing in the kitchen to accommodate our IKEA drawer. I would hire them again for any future projects."

"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."

"Shawn and his crew replumbed our entire house in 3 days while keeping our home useable. We are blown away by their professionalism, work ethic, friendliness, and quality of install. All new water lines in the house, new fixtures, new waste lines, they did a complete system replacement in our home. Shawn and his team explained every step in the process and walked us through what was done and what was left to do at the end of each work day. An amazing 3 man crew in a company full of amazing talent. Harts had previously lined our 100 yr old sewer line and that crew was amazing as well."

"Seatown Electric did a great job and I will call them again when I have electrical repair or installation needs. They were very responsive - even on the weekend. They returned messages and calls promptly. They provided status updates of where my technician was by text message regularly. My technician, Taylor, was prompt, professional and helpful. Everyone that I spoke with at Seatown was equally professional and helpful."

"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 ."

"Veteran-owned business. Honest, reputable and on time for the appointment. Ross and David spent all afternoon clearing out two clogged drain spouts and replaced/repaired a badly cracked PVC pipe after hydro jetting them. They inserted a snake with a camera and showed me the problem. They also provided a veteranâ  s discount! Thank You. Brad Pesek"

"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 Mercer Island, 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.
