"I have used other plumbers before...none of whom did the work entirely to my satisfaction, and many of whom found ways to increase their "firm" quotes. I chose Drain Pro because of their almost perfect 5-star rating. I now know why they have that rating. The man who took my call was Raymond or Raman (Ramandeep Singh), the company president. He was pleasant, friendly, and gave me a reasonable ballpark quote (assuming no major problems). It was not the lowest estimate to do the job, but I wanted it done right. He arrived right on time. The only part of the job that went smoothly was the bathroom faucet replacement, and it went quickly. The kitchen sink partial-clog turned out to be several heavy accretions of hardened grease in one eight-foot section of pipe that had become CONcretions over the years -- some of the grease had come from previous owners...and likely some from us. He tried the big power-snake twice, but couldn't force the gizmo (heavy steel screw-spring) through the blockage. He slithered into the crawlspace to see if there were some abnormality in the pipes...nope. So up he came -- he took off the gizmo, and forced the bare cable-end through the blockages, back and forth several times -- ran the water to see if the blockage was gone...nope, even worse than before (he felt that some of the smaller blockages had moved, become a "log-jam"). He tried it again with the gizmo...nope. At this point he said there were only two good solutions: (a) cut out and replace the section of pipe with the hardened blockages; and (b) bring in the cavalry with special equipment and do a "hydro-jet" clean out -- both these processes would more than double his original bid. But just to be sure, he tried it once more with just the bare snake-end. And lo & behold, the blockage was gone! ...I hope. Raman said it could come back, and we could do the hydro-jet operation, if needed. Then he rebuilt a toilet (several small problems). The bolts holding the tank on were so bad he had to use a sawzall to cut them off. He replaced all the parts, installed the new flush mechanism, and it is now as silent as can be. Hallelujah! With all the problems he encountered, I expected a demand (or request) for more money. Nope. He stuck with his original bid. As I said at the top, his wasn't the low bid. But he did all the work correctly, kept everything spotless clean, and was friendly and cheerful throughout. Without any hesitation, I strongly recommend this company in general, and Raman in particular."

"The plumber arrived with all parts required to replace the hot water heater and accessories. He completed the job, including draining the old tank, installing a new shutoff valve and new water lines. He lit the heater and checked to be sure the system started with no leaks. He came on a Saturday, with no extra charge. Excellent job!"

"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."

"All Pro Plumbing completed a rebuild of three toilets. After Home Advisor recommended them, All Pro provided an estimate within a day, and completed the project within a week. They were on time, very polite, and knowledgeable. Of the three estimates I received for these repairs, they were the least expensive and most professional of the companies I received estimates from. I would definitely hire All Pro Plumbing again and am happy to recommend hiring them."

"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."

"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."

"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 ."

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

When installing a sewer line, you should consider extra costs like tree removal, driveway repairs, or patio resurfacing. Hiring a professional plumber is essential, and you may need additional specialists if landscaping or heavy excavation is involved. Addressing these potential extras up front helps ensure accurate budgeting and prevents sudden cost overruns.

To calculate the length of sewer piping you need, measure the distance from your house to the main sewer line, adding the depth of the city main to this distance. Be sure to account for any obstacles like tree roots or utility lines that may require additional piping.

City sewer lines are installed at a lower elevation to prevent unwanted backflow and water damage. This lower positioning ensures enhanced performance and long-term safety, meeting all technical and safety standards.

With trenchless methods, a plumber inserts a smaller pipe within the existing plumbing, avoiding full excavation. It can be more cost-effective and less disruptive than traditional methods, but it's not suitable for all homes.

Yes, you must secure permission from your local water authority before connecting to a public sewer line. This approval ensures your connection meets all regulatory requirements.

Sewer lines are buried between 18 inches and 8 feet deep, with most systems placed between 18 and 30 inches. In colder regions, pipes are set deeper to remain below the frost line.
