Hired John last fall to clean and perform a water change in the spa that came with the house I bought. (water was yellow and smelled like ammonia) He insisted the water just needed chemicals to "clean it", I finally convinced him to actually replace the water, he also "cleaned" the spa before adding water and chemicals. At that time we agreed on a maintenance contract where he was supposed to perform spa maintenance weekly. At first the water looked and smelled great, however I soon found out that he only spot cleaned the surface, there was a lot of slime and mildew behind the headrests, lining the jet tubes, etc. so the spa became smelly pretty quickly. After 30 days without him coming back to perform any maintenance, I contacted him, apparently he forgot we had an agreement to maintain the spa. He came out a couple weeks later and dumped some chemicals in the water. The entire time he "maintained" my spa he never cleaned it or performed a water change. He only showed up 1 or 2 times a month, sometimes not at all. I gave 2 stars instead of 1 because he only charged me for the work he actually did. He might be a good choice for a repair, but he is completely unreliable and does the minimum to get by. My spa has been unusable for over a month while I looked for another spa company. read more

I hired John for weekly pool service in 2018 to replace our previous tech who retired. John was originally supposed to come every week on Monday mornings like the previous guy did. After a few Mondays going past without John showing up, I called John and asked him to tell me what day and time he would be servicing our pool. John's response was that he was very busy and he was trying to figure out what his routine for our pool would be. His story seemed reasonable at the time, so I let it go. I recently stayed at home two weeks straight and noticed John didn't show up either week. I phoned John on Aug 23rd to ask why he hadn't been coming. He told me he was super busy and had not been able to get to us. He told me that the last time he had serviced our pool was July 30th and he would make an effort to come service our pool during the week of August 26th. I phoned John on the next day and fired him. I took a pool water sample to a local pool supply company and had the water tested. Chlorine was way over safe levels - 11.28 ppm instead of 2 - 4 ppm. I would not recommend Diamond Pool & Spa under any circumstances. read more

I was referred to John at Diamond by another local pool and spa repair guy whom was too booked to get to us in a reasonable time. He was out within a few days, found the pesky issue, and fixed our problem in timely manner. So glad to have a working spa/pool heater once again. Thank you John! read more

Nice guy. Super unreliable. Does good work when he is around. Had to figure out our system and learn how to do it anyway. So I fired him. I would NOT recommend. read more

John is an honest guy who fit us into his schedule to come out a look at a hot tub we had inherited with the purchase of the house. Fair pricing for the service call and parts. If need someone to come service your pool or spa give him a call. read more

John was great in his service call. Thought I was looking at 300.00- 500.00 for a new pump (or Repair) and a bad ozinator. John fit me in to his day and fixed my problems without major expense. He was able to fix the leaking pump and found a very small air fitting that was plugged. He only charged me for a service call and my wife is very happy. Thanks John. read more

My mother in-law had passed away and we had to get her house in order to sell and knowing the pool was a selling point we needed expert help; the pool was in need of an overhaul it looked like a swampy mess. We called many pool companies and Diamond Pool and Spa was prompted in answering the call, asked important questions, addressed our concerns and came out immediately. The owner came out that day and he made that pool look like new! It was beautiful! We really appreciate John's expertise. We would hire him in a heartbeat. Thank you John. read more

DO NOT WASTE YOUR TIME WITH THIS GUY! John is the most unreliable spa service tech I've EVER used. I scheduled an appointment on April 4th to fix a spa leak. He didnt show at 3pm so I call him at 3:15 and he gives me an unconvincing story about running behind and that he'd be there by 4pm. Well, 4pm comes and goes and no John. I call his number at 4:15 and get his voicemail, hmmm. So, the next day I call him twice more and get his voicemail both times. The guy NEVER returned any of my calls and now the underside of my spa is a lake! I'm fed up with this clown and will have one of his competitors out to fix it tomorrow. DON'T USE HIM! read more

I 've been using this service for years and think it's great. John takes care of everything for me and charges very reasonably. He comes on his own schedule but is always there for me. Isabel G. read more
