Ken was really accommodating to find time in his schedule. He came over and we initially thought we may need a new pump but after additional and thorough testing he noticed that the one of tubes were not supposed to be full and solved the problem. I wouldn't hesitate giving him a call if you need your hot tub repaired. 5 stars. read more

Ken was wonderful. Everything from start to finish was spectacular. He explained everything in detail and fixed my pump and jet issues. My hot tub is now up and running. He is fair and honest with reasonable fees. It's refreshing to work with someone who is qualified and does everything they say they will do. Get it done right the first time. He is your guy. I'm thrilled to have had the opportunity to work with him. read more

My entire experience with Ken from Flowmaster was 5 star. From contact to appointment, to repair everything was done professionally and economically. The spa had a leak in one of the main lines and looked like an expensive repair. Ken performed a practical repair that worked like a charm! He explained the system and taught me how to fix leaks like it in the future. Great workmanship and reasonably priced! Now I have a friend in the spa business!! read more

Ken was great - he returned my calls and texts, made an appointment in short order, showed up when he said he was going to, diagnosed my hot tub problem quickly, and came back a couple days later and did the repair. His fees were very reasonable as well. read more

I'll open with Ken is a true Godsend of a human being. We started a repair with our original hot tub company and it was like pulling teeth from a wild grizzly bear to get the manufacturer to own up to bad parts in manufacturing and design. Ken absolutely saved our sanity by fighting with the company for us and just getting it up and working again. As long as it took, Ken got the job done. Parts finally in hand and couple of hours of work it's operational and running better than originally did. I'm grateful for work Ken and the services he provided. Not only did he install and get my hot tub running but he went extra to explain how it works. He even sat down with me to explain basic mechanics of the hot tub system and helped me understand what was wrong with it, defective parts, difference in systems and sanitizing systems and helped me be more prepared the future should anything ever go wrong. More than fair pricing for the amount of work and energy Ken put into getting my hot tub up and running again. He made a horrible situation better in the end, for that. I am forever grateful. Definitely 5 star would recommend 10/10 parts, services, labor, and guarantee of work. read more

Ken is great- a few years ago he responded over text and phone to help me fix an issue myself. It was a simple fix, and he was kind and extremely helpful. About a year ago Ken came by and replaced a blower motor for a jet on my hot tub that wasn't working. Again, great service at a great price. Very impressed. Look no further than Ken for hot tub maintenance! read more

Ken was amazing!! He first spent 25 minutes on the phone with me trying to problem solve my issue and see if I could fix it myself. Then when I could'nt he came out the next morning and went and got the parts and came back that afternoon, even though he had said it would be a week until he could make it back. He understood how important my hot tub is to me, and said he'd make it back that same afternoon. He fixed the issue and his charges are very reasonable. He's been doing this for thirty years, and I felt I could totally trust him. I highly recommend him!! read more

Ken came out and replaced the circulation pump in our hot tub and then came out to replace one of our jet pumps a month later. He was on-time, professional and affordable. I will absolutely be calling him again if the need arises. read more

Amazing customer service. Owner came out to my home twice to do find out why my Hot Tub was leaking. Offered solutions that included no-cost do-it-yourself options. Glad that I selected Flowmaster. Prices were exceptionally reasonable and he explained what he was going to do prior to starting work. Would use again without hesitation!! read more

Ken was prompt. He got the job done quickly and was even flexible to work with our schedule and come back a second time because we weren't ready the first time. The pump we needed had doubled in price due to Covid related circumstances, This was unexpected and a difficult situation. Ken went above and beyond to it right and even taking a hit on his end to make it right with the customer. I will only do business with Flomaster in the future when I need a repair. I highly recommend the Flomaster team read more

I requested a quote through Yelp and got a near instant response. Ken understood the problem quickly and fixed it. The price was fair. He's in my phonebook for repeat business when I need him again. read more

Quick response. Good communication and very fair pricing. Ken even provided guidance to make sure the problem did not happen again.

I had just gotten a new above ground pool and needed help with connecting the filter plus other questions. While a handyman had set up the pool, I really wanted a knowledgeable person to look it over. Plus I had bought a huge sand filter as a back up. Ever try getting pool help on a hot Seattle summer day? No dice. Everyone was busy or wouldn't come out. I called Ken and he was instantly helpful. He knew who I should call and what I might do. When I followed up with him a day later, he made time in his busy schedule to stop by, get the filter set up, assess the situation, and give me his honest opinion. It was a huge relief. He is polite, patient, and helpful. I recommend him, and I will use his services in the future. read more

Thrilled to have found Ken. We'd purchased a house with a hot tub. We have all of the paperwork and parts purchased for the tub. It was purchased in 1983 and has had the pump and heater replaced many years ago. We had an impeller shear off of our hot tub pump. Phoned Ken, received a timely call back. He correctly diagnosed the issue over the phone, informed me that he had the part in his truck. Quoted me the parts and labor over the phone. I was floored. Was totally prepared to get beat up by the sticker price of this repair. This wasn't the case, I was giddy about how well this was working out. Following the call, I was confident that my problem was soon to be resolved by quality work at a reasonable rate. He actually repaired the issue was going to replace the part not try to sell me a new pump. I couldn't believe it. He promptly visited my house to confirm the issue and even came by during the day so I didn't have to take time off of work! Phoned me with the issue (correctly diagnosed over the phone) and left me an invoice! I may not be happy about the next time we need to phone Flomaster but when we do, we won't need to worry about price gouging or surprise expenses. Originally found Flomaster on the Insider Pages when there weren't a lot of options through yelp in our area so we knew we had to add him here. There are deeper reviews on the other sites for a broader history. read more

Ken was a pleasure to work with, very knowledgeable and fair. I purchased a new home with a 20 yr old hot tub that needed some diagnosing. After running some electrical tests Ken had me up and running that same day -- he was even kind enough to take my call later that evening to answert some questions I had as I finished setting up the tub for use. I highly recommed Flowmaste Spa & Pool Service! -- it's nice to know I have a knowledgeable, friendly and fair hot tub repair technician I can call oin in the future! read more

I wanted to provide a follow-up for Ken based on our most recent experience. Our wireless controller stopped working so we called Ken and he came out promptly to take a look. Our control system is new to the market and the industry so some hiccups were to be expected. Ken had it working again right away. He also took the time based on my previous review to explain the cost associated with our initial spa refurbishing work. I'm happy to say that after he itemized the cost for us regarding the increase and associated electrical work, I feel like we got a great deal, especially since he cares about the work he did so much that the additional visit and calibration was free of charge! I changed my review from A-OK, to five stars. We'll keep Ken's business card at the ready in case we need future work. Don't hesitate to hire him and support a local guy who cares about his craft. Previous post: Ken does great work, but price is a big ???. If you can nail him down or track him across the project, do it. Unfortunately, Ken said he "stood by" his verbal estimate of about 2K "at the most" to refurbish the tub we inherited on an old property. His last verbal estimate which he insisted he "stood by" was a little over 2K because of needing a 140 dollar electrical part. We just got the invoice today, 2800K. That's quite a bit over the initial and secondary "stood by" estimate. We'll pay it without too much fuss because the work is good, but it is a surprise. We might hire Ken again cuz the work is great, but not without something in writing before hand and any change orders documented. read more

Ken is super professional! He did excellent job to solve our problems that the previous service didn't find (after 3 visits! and a lot of money). Ken was extremely reasonable in his pricing, knowledgeable, dependable and informative. He is also great guy and very friendly! Thank you Ken! read more

I had a wonderful experience working with Ken. I really appreciated his quick feedback (and free estimate) after assessing what needed to be replaced on my hot tub. He had the hot tub fixed and running very quickly. Ken is an honest and wonderful person. He helped me out on an unrelated emergency issue that I encountered which illustrates how amazing of a person he is, stepping in when he didn't need to. We appreciate his above and beyond customer service and will only work with him in the future! read more

Ken managed to come around quickly given it was the holiday weekend. He very quickly found the issue with a shorted heating element and had it replaced before I could even blink. On top of that he is hilarious too. Glad we called him. Prices very reasonable, quick service and no fuss. We so rarely have good experiences with contractors and handymen but this was one. Thanks Ken. read more

I'm not sure if there is anything that Ken cannot fix. He is very knowledgeable and is very fair with his pricing. I had a problem with my hot tub that no one could figure out what the problem was;.. Ken fixed it over the phone. He's my go to guy for any problems and he should be yours. read more

I live in Bainbridge Island and was having a lot of trouble finding someone to service our Pentair Pool Heater. I called Flomaster in Kent - as a long shot. Ken was kind enough to call back to let me know that during summer the island was out of his service area. That was not surprising but what he did next was truly remarkable. He walked me through troubleshooting the heater for over and hour without charging me! In fact, he refused to take any payment when I offered. He showed a deeper understanding of how these heaters and complex pool and spa systems work than anyone who has serviced our spa and equipment for the 10 years we have owned it. I would highly highly recommend him and Flomaster. I intend to use them when I can get them to the island!! read more

My husband called and made an appointment and knew what was wrong with our hot tub, and asked for quote and and he told him the price of the part. He came and replace the part and again I asked how much it would cost and he quoted the price of the part and told me he would send me a bill and that he only took cash no credit cards. When we received the bill the part price was almost $150 more than he had quoted both my husband and I. My husband called and he did make a small price adjustment to the part. He did a good job fixing the hot tub, but be sure you get the bill before he leaves and be prepared to not charge it. read more

Right at the nicest part of summer our pool heater failed. The issue was intermittent and those things are the toughest to diagnose. But, Ken is a wizard when it comes to pool equipment. He was able to quickly diagnose the problem in an electronic component and knew exactly what to do. He fixed the issue quickly and completely and saved summer for our kids. He was responsive to calls and questions, showed up right when he said he would and completed the project on time and for exactly what he said he would charge. Flomaster is the best type of service provider. They do just what they say they will and they do it right the first time. I will use Flomaster for any future repair needs. I would recommend Ken to anybody that asks. read more

Ken is a great guy. Honest, and helpful. I have a calspa which he could not repair, however he referred me to some folks he thought could. Very friendly. Would highly recommend his services! Thx Ken! read more

Ken did an excellent job servicing our leaky hot tub. Shopping around we received multiple exorbitant price quotes including one company offering to fix our leaky tub for a whopping $1000. Ken was extremely reasonable in his pricing, knowledgeable, dependable and informative. He came by our house three different times to solve our challenging hot tub problem. Each time he worked quickly and efficiently. In the end he made the necessary fixes and now we have a fully functional tub. Because of his quality work, pricing and efforts he has a life long customer in us. Good work ken! read more

We bought a house that came with an old hot tub that worked for a couple months before giving out. We called Ken after reading the other yelp reviews and also the not so great yelp reviews of service by bigger places like aquaquip. within 15 min of looking at our hot tub he was able to figure out what was working and what wasn't. He got the parts within a few days and had it all installed within a couple hours. The parts are obviously expensive but his labor was reasonable and he was very knowledgeable about hot tubs and we did not feel like he was trying to sell us or replace stuff we didn't need. Although overall more money we wanted to spend bc the previous owners really hadn't maintained the parts, he has it working like new and it's much cheaper than buying a new spa when he says the body of the spa is in pretty good condition! Would definitely recommend! read more

Ken has been my "spa guy" for many years. Besides being great guy to work with, Ken's knowledge of hot tubs is expansive. When the pump broke a while back on my old Marquis tub, and a new one was not available, Ken rebuilt the motor himself. Recently, the controller gave out, and Ken made my tub "internet ready." Now, I can control my hot tub from my smartphone! My friends are very impressed. This was no small task, as Ken had to cut my old panel in two and match it to the new control panel. What a professional job -- it looks like the new panel was always been there! The plumbing was also a nightmare, but Ken made it all work. Great job! He comes highly recommended. read more

we recently bought a home with a 'vintage' hot tub (circa 1985). the heater/ pump unit was a rusted heap of junk. we got several quotes to get the spa up and running and contemplated tearing it out when ken offered a solution almost 1/3 less than anyone! once running he discovered some jets not working properly and many leaks in the original plumbing. he made several attempts at just fixing them and because parts were no longer available he retrofitted the entire spa. works great, he said he could bring that hot tub back to life and he did. good guy, sincere in making things right. thumbs up. read more
