Recommended Customer Reviews

A positive plumbing experience....I know, right? These guys were on time, on price, no surprises. The guy running the crew had 21 years experience, not even a hint of the stereotypical stuff you hear about plumbing projects. Our 100 year old pipes AND the section under the street are done and our tree root nightmare is over. I got 7 estimates, they varied wildly. Seattle pipe works was on the lower side, I did my research, they have 5 stars for a reason. Do your research, get estimates, hire these guys.

Tim was very helpful, sincere, and respond e-mails and phone calls very quick. I know the job was too small for Seattle Pipeworks, but Tim took it very seriously and I felt like I could really trust him. He was very patient with me answering all my questions. I would highly recommend this company.

Tim is honest, fair, and took the time to make sure we found the best and least expensive solution to our problems. He never tried to ""sell"" us, and he even connected us with a plumbing contractor when it turned out there was a less expensive way to solve our problem than relining a whole sewer. He has great integrity.

Pipeworks cleaned out our sewer line last summer. Tim was a great communicator and they did a great job. The hole we dug collapsed after they did their work and knocked the clean out sideways. Tim sent a guy out that Saturday to move it back and make sure everything was ok so we could fill it back in.

Disclosure: I did not go with Seattle Pipeworks for my side sewer work, this rating is with my experience with the owner Tim Walsh.
Tim was great to work with. I didn't know much about side sewer Repair, but Tim did a great job with answering all my questions about Perma Liner repair, delivery of a quick quote, and coming to my place to take a look at my side sewer. The customer experience Tim gave was 5 star.

I got wonderful service. Efficient. I had water on my basement floor and knew right away what had happened because many houses in our area had had the same broken sewer problem. I started with another plumber that sent a camera down the drain, found the break and recommended Seattle Pipeworks. Since they were so highly recommended I knew I was going to hire them but I did get another bid just to make me feel better. Everything about the way they worked was reassuring. They had to dig down 9 feet to find the broken pipe and when they were done, they left my yard is really great shape.

A little late on this review, but better late than never. Last year I had the joy of sewage coming up my basement shower drain. After a a scope, turned out to be a big break in my sewage line about 6 feet out. Not only were they the lowest bid by about 20% they didn't try to rip me off by trying to convince me to replace the entire line like most shady plumbers do. They dug out and replaced 12 ft an the best part was they had to dig up rockery and grass and put everything back perfectly. I did have to wait about a week because he was backed up like most people are but was worth the wait. He also said, it's ok to still use water sparingly, when others tried to scare me into needing to fix it the same day just to get the job. Plumbers are worse than used car salesman (northwest plumbing) so if you can find a good one like Tim, you're lucky! Also, if you just need drains snaked like I do like once a year because my 2 teenagers put I don't know what down the drain all the time, then Fritz drain service is awesome and the cheapest.

My wife and I worked with Shawn on a backed up outside sewer drain and had an absolutely fantastic experience. He let us know all of our options, was fair, honest and patient with us, and providing ongoing support as questions came up. I would absolutely recommend Seattle Pipeworks.

If I could give Tim and Seattle Pipeworks a sixth star, I would. Tm provides a level of professionalism and integrity that is almost unheard of these days. We had been in denial about some chronic plumbing issues for quite a while, treating regular backups and not wanting to have to dig up the yard to address the real issue - until there was no longer a choice. Another plumber came out and gave us an ""estimate"" that had an $8,000 range between the possible low and high end costs, and said he wasn't available for five weeks. Tim came out, offered a fixed bid (towards the low end of the other estimate) and said they could start right away. Anyone who has ever worked with contractors knows to be skeptical of a ""fixed"" bid (and mentally add 50% to the estimate) but Tim clearly outlined the scope, the day rate and costs for parts and permits. Tim's crew was hard-working, friendly and professional. They did a great job making the repairs, keeping us informed of what was happening, dealing with unexpected issues, and replanting bushes and flowers and cleaning up the mess after the dig. They took a bit longer than they had expected but Tim, true to his word, stuck to his original bid. These are the people you want to work with.

We called Seattle Pipeworks to get a second estimate on a 6"" liner for the last 35' of our sewer line. Tim Walsh, the owner, came out and talked to us, and then he sent Peter over here to run a camera down the line. In doing the filming Peter said he thought the line looked fine, which surprised him, and he said let Tim look at the film and he will let you know. Tim emailed me back to say ""the line is currently entirely in function condition (with normal wear)"". I am so glad we found an honest company! The other bid we got, for a ton of money, never actually said ""your pipe is broken and needs fixing"" even though they also put a camera down it. They just said ""yeah, we can line it"". Tim did not charge us, and treated us honestly. No higher praise.
