The other day, I called Underwater Poolmasters (UPM) about a problem priming my pool pump. What a surprise that Steve (the owner) answered the phone! Although I know he was very busy with customers, Steve patiently answered my questions and gave advice to resolve the problem. As we talked, we realized that my family has used UPM for almost 30 years!

I can still remember the day Steve came to educate me about the pool operation. Over the years, Steve and his crew have been incredibly helpful with information, troubleshooting, service calls, and reassurances. I feel like I am very knowledgeable about maintaining our pool because of Steve's tutelage--he's a marvelous teacher! (Pun intended!) We're very lucky to have UPM service our pool. The swimming season is so short, and we are able to take advantage of each Sunny day thanks to Steve and his staff at UPM!

First impressions are very important, i called to ask a simple question and the tone from the lady that answered immediately made me want to take my business somewhere else.

We have been customers of Underwater Pool Masters for 9 years. As new pool owners, they helped us learn how to care for our pool, and did a great job with opening, closing, and maintaining our pool all season. They have also done a fantastic job with large pool projects that have come up over the years. Steve, Phil, now Eric, and all the crew are truly pool experts. We are grateful for their knowledge and expertise.

Kudos many times over to Underwater Pool Masters. I purchased a home in Hopkinton in 2011. UPM had performed the pool inspection that summer as part of the home purchase. I live in Hopkinton which is a little outside of their normal service area - so when another pool company left me hanging because this particular pool was "too much work" (it has a spa, heating system ) - I was truly stuck.

I called Steve White (the owner who had performed the inspection) a bit embarrassed that I had even listened to the urging of my neighbor to go with the other pool company for the opening and explained to him what happened. He was as gracious and re-assuring as one might be. What a relief and what a class act. They came down, got the pool, spa and heater up and running without issue and without any complaints that it was "too much work".

I am forever grateful. Steve, Phil, Eric and Lisa (I hope I am not leaving anyone out!) go so far above and beyond that they feel like old friends. I mean that. Little things.tile replacement, filter and pump issues, troubleshooting questions are never seen as an annoyance. In an era where service is not what it used to be, they're a breath of fresh air. They simply have a customer for life.

I can't say enough good things about Steve and the staff at Underwater Pool Masters. I stumbled upon Underwater Pool Masters after calling numerous places near where I live (south of Worcester) over the course of many weeks, I guess my pool situation was not attractive enough for them. I am a new pool owner and knew nothing about pools so I was of zero help.

I'm about 40-45 minutes away from Underwater Pool Masters and I wasn't sure they would even consider it. They did, and they came out as fast as possible, fixed my leak, fixed my pump, educated me on everything I need to know, and got my pool running. Fast and efficient! Thank you Steve and the team at Underwater Pool Masters, you guys ROCK!

Great place, great prices! It would be 5 stars, with the exception being different clerks interpret the pool water readings differently. But, I wouldn't go anywhere else.

Underwater Pool Masters rocks! I tried contacting many pool service companies in the Worcester area before reaching Steve at Underwater Pool Masters and couldn't get any help. I had a couple of the other guys come out to analyze my pool situation, then bill me for analyzing it but no one could/would actually help fix the problems. Then Steve came out took care of my leak in the first visit and guided me to getting my pool up and operating flawlessly and within a reasonable price. I will never contact anyone other than Underwater Pool Masters. Thank you!

Today I visited the West Boylston store for the first time. The owner Steve and his staff were amazing! Extremely knowledgeable, they use the newest technology to test your water and generate a "to do list" which is easy to follow. Underwater Pool Masters has all the chemicals and supplies you need at reasonable costs. Steve is nationally accredited and offers training courses to other professionals and takes the time to teach his customers! Over-all the service was above and beyond what I expected! Do yourself a favor and visit the store with your water sample, you will not be disappointed! Thank you Steve and staff!

If I could give them negative stars I would! We are new pool owners and were looking for a local pool company to work with as the place we bought it from was out in Pepperell. Not only did they give us the wrong opening date but when my husband called to complain they told him it must have been his hearing as to why there was the wrong date given!

They then told me once I filled the pool all the way up I was good to run it. Not knowing how to open it at all we didn't realize that there was no DE in the filter. (That's not included in the opening package) our pump was leaking (not due to the lack of DE but because of how they installed it) they then told us that was another service call. They came back to "fix" it after we complained again and ended up messing it up again.

I will NEVER use this company again. We basically paid $265 for them to dump all the leaves in our pool, take the cover off and connect the components. I recommend Snyder Pools if you want good quality people and service, we have since switched to them. Don't waste your money on the services here. It's a joke.

I went to 4 different pool stores and received very little help! 11 days with a green pool and way too many chemicals that were doing nothing. One visit to Underwater Pool Masters and my pool was crystal clear. Libby told me exactly which products I needed and explained step by step what I needed to do. She was wonderful! F ound my pool place finally!

The worst service ever. I went to the store 5 weeks before memorial day weekend to make sure my skimmer and return could be replaced. I supplied pictures of the parts needed, I called 2 times and left messages for Steve but never got a call back.the third time I called his own employee stated "I can't believe you haven't cancelled this appointment by now". Terrible, terrible, terrible customer service.

I would have rated them zero stars if it let me. STAY AWAY FROM UNDERWATER POOL MASTERS! One of the worst experiences I have ever had. I have used Underwater Pool Masters for years to open and close my pool. I have also used them to purchase products. Up until this year I have always had a great experience with them. Apparently, they now let their service guys (ERIC) do their own scheduling. Well, Eric never showed up on the day he was supposed to open my pool.

Then I was rescheduled to a week later. Again, Eric never showed up (no phone call or anything). When I called yet again to see what was going on, I was told that they can't even get in touch with Eric to find out where he is or what is going on with his appointments. I asked if I would be scheduled for the following day since this is now twice that Eric never showed up to my house.

I was told that Eric's schedule looked full for the following day and that he would most likely not make it. Are you kidding me?! How was my pool not a priority at this point? I was bumped twice with no phone call or anything and yet I was not going to be squeezed in? Completely insane. How do they even think this makes sense? I called again the following day to get an update and nothing.

They couldn't tell me when Eric would be out to open my pool. I then left a voicemail for the owner, Steve. Waiting for his call back and explanation. How could he let this guy Eric ruin the reputation of his business? I can't wait for an explanation.

Great place - very helpful! I was referred here by another pool place which didn't feel like answering my new pool owner questions several years ago and boy am I glad they sent me there! The people are friendly and knowledgeable and go out of their way to help you I recently had an emergency with a leaking hose and the owner stopped by to fix it on his way home rather than making me wait a few days for an appointment during their really busy pool opening season since it was a quick fix. They know me by name and greet me as a friend.

Local folks with good products at the store for easy convenience, prices are ok, there prices for coming to house are crazy high though, $150 just for a truck roll, plumbers electricians etc don't charge nearly this much : decided to try and fix myself
