Business hours clearly say 6pm, got here at 533pm and closed with no one in sight. Knocked on the glass door, no answer. Awesome. So far this location is 1 star worthy. 5.2.25 read more

Been going to this location since 1995 and was just told that they've never carried pool tablets (the large size) to a customers car. Give me a break! In fact I've never once carried the pool tablets to my car. I purposely went there because of the service - as I am unable to carry the large heavy bucket myself. 30 years and a new employee ruins the customer relationship. And it's not as though it's not a $200 purchase or more depending on what all I'd buy. Very disappointing. read more

As a assistant manager, I would've expect some great customer service but what I received was I don't wanna be here vibes. As a new pool owner and unexperienced, I asked a lot of questions and he gave me blunt answers without any explanation nor steps by steps or any tips. read more

Went by the store yesterday to get some pool tile grout , as I entered the store I said hello to the guy behind the register he replied with a very non happy greeting. I asked him where the grout was located and he replied WE DON'T HAVE ANY, I asked him when will you be getting some in , he replied I DON'T KNOW. I believe he's the store manager ,tall heavy set Hispanic guy with long sideburns.this guy has no business working with the public . I'll be taking my business elsewhere as long as he's working there. read more

I experienced exceptional customer service from Danielle this weekend. She went over and beyond her customer service to help me with my lead hose for my pool vacuum. I'm very thankful! read more

If there was a 0 star for these guys at 222S Diamond Bar Blvd, I would give them a "0". The manager is confrontational and argues instead of providing advice or assistance. By the way, he does not honor veteran discounts if you but some chemical that may say 10 % sale. He will also not ask if you need any help with administering chemicals. It just feels like these guys want to be left alone and not bothered by customers. Find another pool service facility guys. Horrible sales people and horrible customer service. Stay away! Horrible customer care. read more

We're newbie at cleaning pool by ourselves; therefore, me and my husband decided to pay a visit at this Diamond Bar location. It's not our first time to Leslie's Pool Supplies but Bethany L has made the differences. We're dealing with Algae and high pH and phosphate level in our house. Bethany doesn't even mind to stay and help to guide us how to deal with the pool. I highly recommend this place for whom who need help with your pool. read more

Come in for the free water testing today, we got the best help from Bethany and Cameron. They assisted us to get the right chemicals for our pool and explain everything in details. Good customer service, I'll recommend this location for those who needs their best help read more

Definitely the worst Leslie's location that I have been too. Special ordered a part, and went to pick it up. The part was given to me without hesitation in a previously opened, stapled shut bag. I looked further, the part was scavenged for the o-rings. Mind you, this was handed to me by the manager with a straight face. I looked at him, explained I patiently waited a week for the part. Look on his face said it all. I will gladly drive out of my way to go to Malins in Chino! By the way, to the manager...you telling the person to pour 1 gallon of acid into their 20k gallon pool and further telling them that it will be safe to swim in after about an hour...YOU HAVE KNOWN IDEA WHAT YOU ARE TALKING ABOUT. Your going to get someone hurt. read more

Very happy with the service. Friendly and helpful. Gives great information and with their help haven't needed a pool man.

Been going here for years, but Bethany's the one who finally made me feel inclined to leave this place a review. Consummate professional, great attitude, provides great insight and advice. read more

Zero star would have been appropriate! I am done supporting small local business! Especially this Leslie store. The service is awful, the knowledge pitiful. I gave the store one more chance to earn my business today. I have a broken directional flow fitting. I walked in and was directed to an aisle of the store where the fitting would be. They had only 3 kinds and none exactly like mine. But one looked like it would have worked and needed to open the package to make sure it was the same size as my broken one. I politely asked if I could open the plastic bag, and was denied.. I was told I need to buy it first.. I was ready to pay twice the amazon price...I told the idiot mending the store and walked away. Don't go there.... poor customer service, no business common sense. Find another provider or just buy off amazon. read more

I am a 20 year resident and homeowner here in DIAMOND BAR and I've been coming into Leslies Pool supplies here the entire time. I have seen several managers and staff come and go, but I've got to admit that the staff that is there now is pretty good. However, Bethany L is the best! She always greets and takes her time with each she serves with a positive attitude and smile. Not only does she multi task seamlessly, but She is a straight shooter that is extremely knowledgeable about her chemicals and products and she has always recommends the appropriate steps to take to correct your pool issues. Thanks Beth, Robert, and the rest of the team. read more

Were you ever not a fan of a business and then after time you realized hey it's not so bad after all. Well this Leslies and it's amazing staff have come to grow on me. It's quite simple, buy the necessary supplies to keep your pool blue and you will not have any problems. From Robert to Bethany they are truly a pros pro when it comes to taking care of your pool. Even though prices are a high you can always depend on Leslie's pool supplies to perform when it comes to treating your pool. I will definitely continue to shop and buy all my pool needs at this wonderful store. Special thanks to Bethany for assisting me with what I needed today. read more

Great Service Bethany rocks ,she's very helpful . Had pool water tested and all her recommendations worked . It's nice when you walk in and get greeted with a smile . read more

Ok well stay waiting for part been over 3 months haven't heard a word from Leslie Pool Supply many promises but no action.Last repair man left his tool here.Not a good pool supply to do business with. There will be no more pool heater bought from this business I can't believe this is so unprofessional to leave a customer who's been loyal to Leslie Pool Supply for last 15 years hanging. Really sad!! read more

I love the new manager I think her name is Cynthia it appears to me that this business has improved since I have been coming here for one year. She is patient knowledgeable and always eager to help. I have received so many suggestions from Cynthia that have really helped my Jacuzzi. I buy all my products from them now. read more

I come here about once a week to have my water tested. Today Kay was super helpful! She not only helped me understand the results of my water test, she helped me find what I needed to make my pool sparkle! Next time I will ask for Kay. read more

The guys- Matt and Joe- are so helpful! I just started taking care of the pool when last summer completely walked me though what I chemicals I need and should buy because apparently I didn't have any which is why the water was green. They only sold me what I needed and always steered me away from buying stuff that I really didn't need but I could buy if I wanted. My pool has been looking great for months now. I wouldn't have been able to do it without Matt and Joe. They have patience when I come in and ask tons of questions about new products or just want to come in and chat about my pool. If you are a first timer taking care of your pool I'd definitely advise you to take your pool water to this Leslie's and to pick the brains of these 2 extremely knowledgeable guys. read more

I tried to purchase a swimming cap this week and tag on the product said $2.99. I thought, cool! Not too expensive for end of summer and limited time to swim. Rang it up and they said it's $5.45. I mentioned that the price on the item says $2.99. He goes to check with someone, comes back, and tells me that's the suggested retail price. They didn't give it to me for $2.99 even though that's the price the item is labeled with. UNPROFESSIONAL!!! It's their fault for not tagging their products effectively and well. They should have honored the $2.99. read more

Went there twice to inquire about pool equipment and parts. For both times I was disappointed at their service. The employee there was trying to be helpful but he doesn't know what's he's talking about. If it's just a simple you have this, yes we do or nope we don't, then he's good for that. But when it comes to more complicated stuff like what brand and size of a heater I should get for my pool and why, you will have no idea what's he's talking about. When you are not sure about something, just check with your manager or look up in your system, don't just try to bs it through. Customer can be knowledgeable enough (Note: "Internet") to tell the difference between a piece of real advice and bs. The manager knows his stuff but was never friendly. Was even rude to his employee too. He's always seems to be in haste of something or somewhere else. I'd say go to the Leslie's pool in Chino Hills, and ask for Jeff or John. You'll get the 5-star service there. Never coming back here. read more

Been using Leslie's for maybe ten years. Not sure how long, but I've been consulting with Robert -- sometimes once a week when my pool gets "moody" -- for the past 2-3 years at least. Gotta say, this guy knows his stuff. I learn something new nearly every time I go in! I no longer give Yelp reviews unless I'm impressed at a 5-Star level. Leslie's (and especially Robert) have earned each star. read more

Best place to go to for Pool supplies and advice!! Cameron is the person to go he is very helpful and will give you the pros and cons of every product to use for your pool. He is also very patient as well and I bought all my stuff from him because of his amazing customer service he gave me and my family. Also, this Leslie's location was very clean and tidy which was another plus as well. Overall, amazing experience as being a first time pool owner from Cameron and his staff! Would definitely recommend him to any pool owner!!! read more

Bethany from this store have given me the hope that I can do the maintenance to my in-ground pool. I been going to this store for years and she was the first one who have walk me through step by step to resolve my algae problem for months. It took only four days and my family enjoying swimming. I hope Leslie's Pool have more people like her that know how to have a great customer service. read more

After recently having my pool replastered I was fortunate to have Bethany do the testing on the water sample that I provided. I've been back to the store a couple of times since then and luckily Bethany was working. She's extremely thorough with the tests, the advice she's given has been right on. If you live in the Diamond Bar area I would suggest asking for her when you go into the store. She's very knowlegable. read more

DO NOT SHOP ANY @ Leslie's Pool Supply. Yesterday I visited the DIAMOND BAR Leslie's to see if I could return an item I had purchased at another Leslie's store. I was told that the girl working could not return pool equipment and that I would need to come back the next day to deal with the manager. I thought okay I will just go to a different Leslie's Pool and so I think I will call before I show up, maybe it is a policy that clerks cannot take back pool equipment (stupid policy but oh well). So I call the CHINO HILLS location, and the gentleman who answered the phone said he would need to talk to his manager and would call me back. I gave him the information from the receipt, and my contact information. He called me back and said they can take it, but it would cost me 15%, because they cannot sell it as new. I informed him that I did not open the box, that the store it was purchased from had opened it so I could see the product before I bought it. He said sorry the policy is that if the box is open 15% restocking fee. So I called the store the item was purchased from and asked if this is the policy, I was informed that they just do not want to take the item back and if he was willing to be called to confirm he opened the box, because he did, and that I might want to escalate the situation and talk to the manager. Why should I have to talk to a manager to return an item that was never used, three days after purchasing the item? Sorry Leslie's you are not the only pool supply place around hence I needed to return the item. I had the receipt, the product was purchased less than 3 days before, never was used; this is just bad policy and reflects poorly on Leslie's. I WILL NOT SHOP at Leslie's again because of this. Imagine if I had bought more than this $300 pump, $50 to return an item that they can turn around and sell for full price with one piece of tape. NO WAY! Let's say I bought a whole new filter system and brought it home and found out it will not work with my pipes or something. NO THANK YOU! Not a risk worth taking. Leslie's may be the closest game in town, but they are not the best in pricing, they suck at customer service (See my Hacienda Height review) and they have a crap-tastic return policy. I get better customer service from the internet then I did here and from the WEST COAST POOL SERVICE who installed the pump I ended up with. I would rather wait for the item on the internet than give one more dime to this company. SILVER LINING: Had it not been for the nice customer service oriented store in Lancaster (Cody was the sales guy there) I would have been stuck. Yes I had to drive from the Diamond Bar to Lancaster (96 miles one way) to return an item, hard lesson to learn, but I am done with Leslie's for all my pool supplies, no fault to Cody and the Lancaster store. read more

I wish I could give zero stars. I recommended Leslie's to a friend. What a mistake. I am humiliated because they exhibited the worst customer service and she hadn't even purchased anything from them yet. What a bunch of losers. Don't even waste your time with these jokers, you will regret it. First of all, over two weeks to come out and give an estimate on what was needed. OK, whatever. She made an appointment anyway. They could not narrow the time down to less than 4 hours (we will be there between noon and 4:00, you know the drill). Then after taking the day off from work, they never showed. No calls, nothing. After she called in, they said the technician called in "sick" and they would call back to reschedule. Great. A wasted vacation day, and she had to call them to find out what happened. Then they auto rescheduled, but was not on a day when she could be home. Was not able to get through to cancel or reschedule. But it didn't matter, because they did not show that time either. If they were this bad before she bought anything from them, imagine what they would be like after she gave them some of her hard earned $$$. I guess they don't need any new business. So take it elsewhere. Will never go back. Too bad, I liked the place before. But they showed their true colors. Move on. read more

Just spoke to someone named Robert trying to buy some paint for a fountain. While he was very polite, he just rushed me as fast as he could. His favorite words today were "I don't know"...Not a good way of treating customers, IMHO. read more

First time at a Leslie's pool. New pool owner. Bethany was very helpful and informative.

Matt was awesome. First time owning a pool, he gave me a full water analysis and helped us solved the pool problem for $13!

Needed some products to get my pool started up after being empty for a few months so I called these guys,,,oh my GOD simply the rudest people ever, Bob you were no help what so ever . Get some customer service skills bud,,,I won't be spending and penny here!!!!! read more

don't seem to care kind of attitude. I've been to other stores where the ppl in the store will chat and help you carry out the heavy stuff. not this one. read more

Just tried calling them right now to inquire about variable pool pumps. Before I could even finish my sentence the store rep Robert said : "I'm right with a customer do you want to hold or do you want to call me back?" At least let me finish my sentence or let me know that you're putting me on hold at the beginning of the call. You sound like you're trying to rush my call. Shows how you take care of your customers read more

I was here a few days ago right before closing to test my water. Bethany was very helpful at answering my questions because I was having issues with my pool. Definitely will be back. Great customer service. read more

Visited this store many times. This is one of the better locations I have visited. Staff very knowledgeable and helpful. Robert the manager was extremely helpful. Receive some great advice on fixing a persistent green algae pool problem and haven't had that issue in about 2 years Also took my pool cleaner there recently for major repair which was completed in about 30 minutes read more

Bethany was a great help to us! She's always super patient and willing to help in any way possible. Also, she's a great conversationalist :) would recommend coming to this store for great service read more

Went in yesterday for some advice on the pool in the home we rent. Our landlord is out of town for a few weeks and I needed some immediate help. They tested my pool water and told me how to fix it. I was very appreciate for the friendly assistance especially since I didn't buy anything. Joe was very helpful! read more

Staff was very friendly and knowledgeable. Use to drive to Rowland Heights, but now there is one in Diamond Bar. Yea!!!! Free water testing too. read more

I came in for a water test. I was next in line and the person helping me started the test and then walked away to help another customer. My sample was left mid test and the other employees started tests for the people behind me. Essentially, I was pushed to the back of the line when the employee took my sample and walked away. When I addressed my concerns, they seemed apathetic and unapologetic. Perhaps because this is a free service, they feel my time is not worth their efforts. I didn't bother to purchase anything since I was there. Out of principle. Thanks for nothing. read more

Joseph was awesome. He was able to help four customers at the same time and get us all out of the store in a relatively short time. His knowledge of the different pool vacuum systems made it easy for him to repair my system. He did the repairs while I waited and had the system apart and back together in no time. I will definitely go back there again. J. Radtke read more
