Recommended Customer Reviews

I honestly can't think of a single thing that Phil could have done to make things better. I would recommend Alki Sewer to anyone in need of sewer help.

I have a clogged downspout next to my 1912 house and wanted someone to take a look at it. Phil came out the next morning and not only gave me a bit of history about my house, but advised that I just reroute the downspout instead of digging a 60 foot trench.. no charge and a free history lesson. What a sweet guy.

I hate to give someone a single Star but Phil has gone off radar in recent weeks. I had a quote and a general time to start the work but has gone completely AWOL over the last month - emails, phone calls etc without response.
I really hope Phil is okay and if someone close to him knows of any issues please let me know.
Otherwise it feels like there's a complete lack of responsibility from this business and I would not recommend them.

We purchased our 1909 Craftsman in January of this year. We had the sewer scoped at the time and knew that we had a new sewer in our not too distant future. In December, we finally decided to be proactive rather than waiting for it to fail. After doing our due diligence and contact several service providers, we decided to go with Phil of Alki Sewer. His rate was competitive, but above all, he was the most responsive and comprehensive in developing his estimate. We got the feeling that he understood the scope of the issues and would provide a resolution that was permanent.
Phil arrived promptly on the start of the job, and his crew persevered through temperatures in the 20's to get the job done. There was minimal to no intrusion on our regular routine, and he kept us well updated throughout the job with regular e-mails and calls. I stopped by the house several times during the few days that work was going on, and Phil was always on the job site making sure that everything went according to plan.
He has a good relationship with the city inspectors which made the completion of the job a breeze. He's a down to earth friendly guy, and a family owned local business on top of that.
Bottom line, if I could give more than 5 stars I would, but since I'm limited, suffice it to say that Phil and Alki Sewer are your guys for any sewer repair/replacement job you could want.
The neighbor was so impressed by what she saw she scheduled Phil to replace her sewer line the following week!
Quick edit, forgot to add that, at the end of the job, everything was put back to normal.

We bought our first home in July, knowing that we were looking at a full replacement to the street. We called Phil, who came out promptly for an estimate. He was thorough and professional. He explained in full detail the process and how everything would go. He encouraged us to get other estimates, and we followed his advice; however, Phil's estimate was very competitive in cost and offered a much longer warranty than either of the other two bids.
The work went flawlessly, was quite high-tech, was complete in two and a half days, and we couldn't be any more satisfied! Everything is working fine now and we shouldn't ever have to worry about the sewer again.
I highly recommend bringing in Phil for your sewer repair needs. Prompt, professional, knowledgable, and extremely high quality work. Call Phil, get your other bids, and then bring him in. You won't be disappointed. Sewer repair is no small job for which we were quite nervous. Phil made it all right!

Phil from Alki Sewer came out to unclog my toilet after hours the night before Thanksgiving and was at my home in a matter of minutes. He was fast, friendly, and solved my problem in no time. I recommend him wholeheartedly.

I unexpectedly found myself with some sewer problems resulting in water and sewage backing up into my basement after a shower and brushing my teeth one morning. I had a sewer snake performed by Raymark and subsequent video inspection showed that my 70 year old cement pipes were full of well-established tree roots and crumbling. Based on the condition of my pipes, I decided to have them replaced.
I obtained quotes from five different sewer repair shops including Raymark and Metropolitan Sewer. When I called Phil for a quote, I was looking for some general numbers based on previous quotes provided by competitors, but he was adamant about coming out to review the property in person and talking me through what the repairs would involve. During his visit to my property Phil walked me through everything that needed to be done and even discovered some additional items that other competitors had missed - for example my gutters were running into a PVC pipe that dumped underground a few feet from my house.
Phil's quote came in several thousand dollars cheaper than the other sewer companies and he was the only person who guaranteed the quoted price would not increase. My joint sewer line was unfortunately located under my neighbor's beautifully landscaped brick wall and to help diffuse the concern of having to take the wall apart, Phil guaranteed the wall would look exactly the same after as before, including a warranty for future problems with the section of the wall that was impacted. Again, he was the only person to guarantee this. I ended up selecting Alki Sewer to replace my sewer line with the pipe bursting method as well as stub a pipe underneath my foundation for a future bathroom in my basement.
Work lasted around a week and Phil and his guys were very communicative about the times that my sewer would be unavailable. Typically the sewer was only off from 9AM-1PM each day which was convenient because it allowed me the use of it in the morning and after work. When I had concerns or feedback for Phil, he immediately addressed the items with his team. During the course of work, there were two key examples of the type of hard work and honestly that Alki Sewer brings that I'd like to highlight:
1. I had originally asked for a pipe to be stubbed underneath my basement slab for a future bathroom next to where the sewer pipe comes out of my house. After digging the hole to fix the sewer line, Phil discovered that a future bathroom could connect to my original sewer line without the need to stub an extra pipe. This ended up saving me a good chunk of money and the key take away is that Phil was honest about not trying to take my money for a service that I didn't need. He could have put the pipe in and charged me for the work and I would never have known the difference.
2. During the pipe bursting, Phil discovered that my tree roots were so bad that it almost broke their equipment. To successfully pull a new sewer line, the team had to dig an additional, unanticipated hole about 5 feet x 12 feet x 9 feet deep. This surprise ended up adding an extra day of work to the job, but true to his word, the quoted price that I paid did not increase, despite Phil having to pay for extra day of work for his guys. Once again, Phil demonstrated his integrity by keeping his word.
When the job was all done, the guys spent a day getting the yard back to normal, restoring the wall and cleaning up. I had some friends over for dinner about a week after the work and they commented that ""you can't even tell that any work was done."" I consider this a high compliment for the work that Phil and his team have done. Thanks again to Alki Sewer for the quality work they put in and I'd recommend them to anyone looking for sewer repair.

Fantastic! He just came by to inspect my sewer and gave me an honest opinion. He was knowledgable about potential problems and educated me on the best way to fix them. More importantly, he wasn't trying to sell me services to fix my sewer like another company did. The other company wanted to charge me $17,000 for something he thought looked fine. I appreciate his honesty and his no-nonsense approach. I would definitely recommend Alki Sewer and I intend to use them if we decide to do any work.

Phil is phenomenal! He gave me free, good advice, saved me over 5k.
I had a backed up sewer line. A major pluming company came out and wanted 369 to snake it, did a bad job and told me I had a collapsed sewer line and wanted $6700 on the spot to dig it up and fix it. Yea yelp!!! I saw SWP had bad reviews and Alki Sewer had good reviews so I got a second opinion from Phil. He looked at it for free and recommended I have it power jetted because of some special situations (the line runs under a stream and it looked like dirt in the line) he recommended a company that would do it right for a fair price, he had them call him after they were done and he came back out to review and confirm everything worked. He never charged me a dime and saved me from needlessly having to replace the line. Phil is honest, smart, knows plumbing and likes helping people.

If you want someone PASSIONATE about sewers, Phil is your guy! We live in a 100 year old house and as our neighbors started replacing their sewers one by one, we knew we were living on borrowed time with our old clay sewer that from one DVD I saw had roots growing inside. I got 4 bids from different companies, but after walking around with Phil, I knew he would be our sewer guy. Quite a character, he was the most thorough in assessing the drainage system from the side sewers on, even removing an upstairs toilet just to make sure it was not tied into the gutter/sewer system. Only until he was satisfied with understanding the way the whole sewer system worked (seemingly for his own edification), was he comfortable drawing up a proposed solution. He explained to me what he found (I now know far more about sewers than I ever thought I would!). He gave us a detailed outline of our options from the most expensive and complete fix, to the least expensive solution of what absolutely should be done to avoid a sewage backup, and what could get by with a maintenance program of regular clean outs.
He told me that he because he spends so much time with the diagnosis aspect, he never goes over his proposed $amount. I believe him! The other companies spent less than half the time and the proposed cost even had vagueness worked into the proposal. A bad sign!
We chose almost a complete fix. This was a big job, but our sewer was repaired within the allotted time (5 days) with several people working during the day. We were able to use the sewer every night. We're a family of 6, so this was much appreciated! A rival company even told on Phil, so a city inspector showed up during that time (the nerve!), but Alki Sewer came up shining! Phil even threw in 2 Toto Drakes (""plumbers toilets"") for free to replace the leaky toilet he had checked out during the diagnostic phase (also, our master toilet was not great either). They work great!
I would highly recommend Phil with Alki Sewer in a heartbeat. He gave us a lifetime warranty on his sewer work for as long as we live in this house to boot!
