Sean and Alliant pool services just completed an installation of new pool equipment for an inherited home pool. My grandsons were able to use the pool and spa for the first time in years! Sean is friendly, knowledgeable, responds to questions quickly and fair in pricing. We were glad we got the referral to his company! read more

Very honest and straightforward. He gave me my options and explained everything I would need to do with the new pool heater.

Had an issue with a jacuzzi and Sean talked me through potential fixes and then followed up with me the next morning with more insight on fixing the issue. If you're in need of his services I highly recommend him. read more

I am very happy that I switched my pool service to Alliant Pool. Sean in always on-time on the day he is scheduled on and takes care of pool in the best way. He is always available for us and so responsive to all questions and concerns we have regarding our pool. This gives me a peace of mind that I always have him around for any issue. He is very responsible, polite, professional and we are all very happy with him. Pool is always clean and he is always available for any question we might have :) I recommend him to all my friends and family. Thank you Sean read more

When I moved into my home the water feature connected to our pool stopped working I had called a couple of pool technicians to come out-one never showed up and the other never followed through after the first visit. Sean is a true professional he showed up to my home right away ordered parts and installed them as soon as they came in he checked in a few days later and is always available to answer questions or come by if you have any concerns. I highly recommend Sean for any pool services you may need! read more

Very glad I found Sean here on yelp. I texted him this morning as my spa heater wasn't working, he called right back and came right out. He assessed the problem and was able to fix it right then! I will be using him again! read more

Quick response, courteous and efficient service - Sean provided professional repair at a reasonable price in very short order. I liked that he was able to re-use a spare part from another system. I highly recommend this company. read more

Sean lived up to his reputation. He responded to my request quickly and was able to assess my pool pump issue within a couple days. To his credit, he gave me an honest review and even some items to watch out for. As it turned out I didn't need a repair or replacement at this time but when I do I will undoubtedly contact him for the work. This is 5-star service. read more

I recently purchased a home with an in ground pool and have been pulling my hair out trying to figure out how air was getting into the system. Sean offered to come over within 24 hours to inspect and diagnose the issue. He was straight forward, open, and even sent me the links of what parts I needed if wanted to do the work myself. Sean's willingness to share knowledge without charging an arm and a leg speaks volumes to his company values. I will give him a call next time I need help with my pool! read more

Sean is a lifesaver! Our pool was leaking presumably when we purchased it and when we finally realized it a week or so in, we panicked and called 10 leak detection companies scared that we had something major on our hands. Sean was one of those calls and after hanging up with him, I called my husband immediately, so excited I had found someone who would stop by and take a look without charging us $500! He was able to locate the leak and fix it within 12 hours of calling him, and all for far less than any leak detection company! We are so thankful we found Sean and will be calling him for all of our future pool needs! read more

We just bought our first house and were very excited to have a pool for the kids to swim in all summer. We had planned on doing the maintenance ourselves but 3 days after moving in I started to panic when the water became cloudy and the bottom was full of debris. Sean came over within 30 minutes of contacting him and he went right to work, not only solving the problem but teaching me how to do the full spectrum of service myself. I was so grateful to have a pro on board to get us started but also really appreciative he was willing to show me how to continue with the goal of maintaining the pool myself. He sent me links to all the items I should purchase to keep things running smoothly and has offered to consult via text anytime I have a question. I was very impressed with his prompt attention, knowledgeable instruction and friendly demeanor. Sean was a lifesaver and will get my quick recommendation for all things related to pool care. read more

Sean is great! He came out to service our spa last minute on a Sunday. He's very friendly and knowledgeable. He offers weekly pool/spa treatments at an affordable rate. We will definitely be using Alliant Pool Services for our spa needs going forward. read more

Seans awesome. Couldn't give a higher recommendation. It's hard to find someone you can trust to not rip you off and also respect your property like it was their own, Sean is the right guy for the job. read more

I highly recommend Sean from Alliant Pools. Always professional, informative and courteous. This was our first pool and Sean explained everything and even told me how to save money if I wanted to clean my pool filter on my own. He is always willing to answer questions and is willing to be flexible with his schedule for abnormal requests. He has kept our pool in great shape and is always proactive. I never have to worry about anything. Also competitive on pricing. read more

I found these guys on Yelp and called them based on their reviews. I had a nasty spa to drain and clean and didn't have the time to do it myself. Sean came out the next morning and went right to work and did a GREAT job! Bad poll service companies are a dime-a-dozen but the good ones are hard to find and Sean was a diamond in the rough. I highly recommend Alliant for all of your pool/spa needs! read more

I highly recommend Sean for all your pool repairs and services. I had a problem with my heater Sean gave some ideas that might fix it over the phone. When the trouble shooting didn't work he came right over and fixed it in about two minutes. Then he tried to not charge me. Totally professionally and knowledgeable. This is the guy I call when I have a problem with my pool. read more

When my pool pump unexpectedly broke, Sean from Alliant Pool Services was quick to respond and come by for a quote. He was very friendly, took the time to explain my options and provided a very reasonably priced solution. He fixed the internal motor instead of forcing me to replace the whole system. I have referred my friends to Alliant and they will definitely be my first call to fix/replace my aging equipment. read more

Alliant pool services offers beyond a doubt the best pool service I have experienced. After a recent home purchase with a new pool, I felt the previous pool service company was over charging me. Sure enough they were. I called around to different companies but none offered me the price and service that Sean from Alliant pools did. After helping me for a few months keep my pool sparkling fresh through the summer. He recommended and installed for me a way to save some serious money with a new variable speed pump. This pump has single handed saved me lots of money this year and on top of that had let me run my pool longer which has let me keep the pool clearer! Sean did a stellar job installing the pump and continues to service all my pool needs and questions. I can't recommend him enough!!! read more

Sean came by to fix my pool today. Its Sunday. It took him 5 minutes to get here. Who is this guy, superman? Simply amazing. He is a down to earth and very nice person. Gives an honest assessment and got me up and running. Super impressed and highly highly recommend. Did I mention you should call him? I thought I would have to wait till who knows when. Still amazed im watching football with pool working and it was very reasonably priced. I will be using him for everything I need in future. He made a great first impression! read more

Sean from Alliant Pool services does a great job he's honest quick and knows his stuff. Anyone with a pool needs to use him. My pool has never looked better! read more

I just moved into a new house and the pool was not looking very great. Sean came straight to our place and got to work. After 2 weeks out pool looks beautiful! He is very knowledgeable, friendly and punctual and is happy to answer any and all questions. He offers weekly pool service that is comparable to others in town. I highly recommend him for any and all of your pool needs. read more

I highly recommend Sean from Alliant Pool Services!! We recently bought a home with a pool and quickly realized that our electrical bill was taking a hit with running our older pool pump. Sean recommended a high efficiency pump and he installed it a few months ago and our electric bill has gone done significantly. We did some searching around to find someone of quality, but that didn't cost an arm and a leg. He had extremely reasonable rates and obvious knowledge of pool maintenance and pump installation. I recently recommended to my mother and he was able to fix their pool issues as well. Without a doubt, hands down, go with Sean (Alliant Pool Services)! read more

Recently I changed my weekly pool service provider and I went with Sean of Alliant Pools. Sean has been so nice and so professional, and my pool looks great. But here is why I am writing this review. Today when I said hello to Sean he said "Look at this." He pointed to my pool light, which has not worked for a DECADE, and was working! Sean diagnosed and fixed the problem for me, all while I was away on vacation. I am thrilled to know I have a pool light again for night swimming and entertaining this summer. AND, he never lets my cats out of my backyard! I highly recommend Alliant Pools (and Sean). read more

Sean is awesome. He did a great job on my pool cleaning and fixed my light for a huge discount over my pool remodeling company. I would definitely recommend him! read more

Sean is very knowledgeable when it comes to pool maintenance. I've known Sean personally for over 20 years, he's always been honest. If you're in the coastal area of San Diego and are looking for a pool guy, Sean Williams is your man! read more

Sean came to clean my filter for the first time. I was very impressed. He knows above and beyond pool maintenance. He is very intelligent, he is still learning of the internet electrical repair. I am planning to hire someone for weekly cleaning in the near future, I definitely will call him. I highly recommend Allient Pool Services for all your pool needs. read more

Sean is a really honest and knowledgeable guy. I had him out to evaluate a situation and he was gracious enough to refer me to another company and did so without charging me. I was so impressed with him that I will be using him going forward for our weekly pool service. read more

I was amazed how hard it was to find the right technician. You figure, it's just a pool and I'm sure everyone would do the same job...WRONG! I don't consider myself a picky guy and when you pay for a service you should get that service. I am so glad we finally found Sean. My pool gets used often, I have 2 kids and 3 dogs who all love to swim (sorry about the dogs Sean), and it has never been cleaner or better. My pool pump was old and Sean installed a high efficiency pump and I've noticed a marked decrease in my electricity bills. Sean is a super friendly guy, very professional, and seems to take pride in the work which is HUGE for me. Honestly you are making a mistake if you read this review and choose anyone else but Sean. I don't review much but feel sometimes that if I can save someone time and hassle, it's worth it. The prices are more than fair and there doesn't seem to be anything Sean can't do in the pool world. Our pool now is the central point to our backyard and outside use and I am incredibly thankful to have found Sean and this company. Stop reading now and set up an appointment. read more

Don't call anyone else! Alliant Pool Services has to be the most reliable and reasonably priced pool service out there! I was visiting my mom and saw her pool was a mess. She said she her pump was broken and it cost too much to repair it. I called Alliant and Sean was at my mom's door within an hour and fixed it for less than half the price my mom had been quoted. Sean was fast, smart and friendly. My mom will only call him for all of her pool needs from here on out! I guess he's part of the family now! read more

Called Sean based on the Yelp reviews and he lived up to the five star reviews. Tried to input a 10 but the rating would not take! Knowledgeable dependable and got back to me right away after I cold called him with some issues I had with my in ground spa. Sean came right over, you can definitely tell he is a local Carlsbadian. Found me an awesome affordable solution to both of my pool pumps going out at the same time as well as an issue with my heater, after my last pool guy could not or would not diagnose even though supposedly repairs were included in my monthly fee. read more

This is my very first Yelp review. I've never felt compelled to write a review until now. My family and I took a quick family trip to Carlsbad, CA during one of the hottest weekends of the summer, so of course we were all looking forward to jumping into the pool as soon as we arrived at our rental house. When we got there, we were extremely disappointed when we saw how filthy the pool was. I quickly called the management company as well as their emergency number and no one called back. With time slowly ticking away, we decided to take matters into our own hands and call a pool service company. I went to Yelp and called Alliant Pool Services, since they had great reviews. Well the reviews weren't lying! I explained to Sean our situation and he was at our house in 10 minutes on a Friday night after 6:00 PM! Wow!! He was very knowledgeable about pools, not to mention courteous and friendly. Also, considering it was such a last minute emergency, we expected to be charged at a premium, however, his pricing was very reasonable. He even came the next morning at no extra charge to ensure the pool was clean and everything was working properly. Alliant Pool Services saved our family vacation and we are extremely appreciative of Sean and his excellent customer service! read more

Thanks to Sean at Alliant Pool Services our family enjoys a crystal clear and perfectly balanced swimming experience all year. He has gone above and beyond to keep our system working top notch. He is a true technician of his craft . read more

Sean fixed a broken pump super quick. He's super easy to deal with and knows his stuff. Would use him again in a heartbeat

Last winter, Sean of Alliant Pool Service was recommended to me, when my pool heater broke down. Sean took a lot of time to correctly diagnose the problem and recommend a range of repairs/replacements that fit my budget. Recently my pump stopped "sucking" and we had a pool party planned for the following day. Not wanting to host a green pool party I texted Sean at 6:30 AM. and he texted me back within the hour. He offered a suggestion for me to try, and it worked! read more
