"Everything was excellent. The team identified the hole in our pool liner. On the day of replacing the liner, identified a potentially severe issue with the structure of the pool. Provided a recommendation for a replacement pool. Proceeded to remove the old pool and excavate the land in preparation for construction of the new pool. Once the new pool arrived, they constructed the pool and constructed new outline landscaping around the pool. We are now the envy of our neighbors who have all watched and gazed in amazement at our new backyard oasis. For all of your pool needs, this is who you need to contact ASAP."

"They did a pretty thorough job. We've been pleased with them so far. Everybody has been very nice. They've pretty much been reliable. When they say they're going to come, they come. They get back to you. It's a good recommendation. They showed up on time, cleaned up after themselves and seemed to work pretty steadily. They were friendly. We didn't have any problems. They did what they were supposed to do and their prices were reasonable for what we thought they did. They said it would take about a day and they did it in about a day. They were upfront. There's not that many companies that do what they do, so we didn't do a lot of comparison shopping, but we thought the price was fair. I've been using them for maintenance work."

"I highly recommend this business since they did such a fantastic job installing our patio pavers. They used a laser to ensure that the patio was perfectly level and also ensured it drained properly when it rained. They also recommended a quality paver and went the extra mile to make sure that we were happy with our patio. They are definitely professionals at what they do and are highly skilled. In addition, they were always professional and friendly and worked very hard. We would definitely hire them again!"

"BJ Pool & SPA is a first rate company. Bob, the owner, has been working with pools for decades and knows everything about pools. He is actually willing to try to repair equipment, unlike many other lesser companies that merely put in new stuff. If you have any issues with your pool and spa, these are the people to call: they will fix anything and will always provide you with the best options. Bill, the specialist who came to work on the unusual configuration of equipment for my small indoor pool and spa, demonstrated a great deal of experience, ability and honesty. BJ Pool & Spa might not seem cheap, however, given their vast knowledge, experience and technical ability, they will provide you with quality service and advice that will save you money in the long run. Their competence and integrity is extremely reassuring. It isn't always easy to find a good pool company (this industry isn't as regulated as other professions), and it took me a while to find this one. BJ Pool will be the company I call when I want honest and reliable service

"Hristo did everything possible to get the job done. This particular June 2016 was filled with many rain days and made his schedule hectic. He kept me in the loop and was up front and honest about the delay noting vinyl liners must be installed in dry, sunny weather - none of which came for a few weeks.
The job was handled quickly and professionally while his team made several visits to complete the job. During this time we got even more rain but the liner was installed by then and they finished all well within the timeframe.
I write all this because Hristo kept me informed which I appreciated and which has earned him and his team my respect and gratitude.
A job more than well done! Also, within budget :)
