"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 :)

Install Above Ground Pools FAQs, answered by experts

Calcium hypochlorite, or cal-hypo, tends to be the best shock for an above ground pool. It is widely available, affordable, and powerful. Cal-hypo shock is typically 65% to 75% chlorine and is very effective at ridding a pool of bacteria or other contaminants.

Your contractor will need several days to several weeks as far as a timeline to install your semi-inground pool goes. Adapting an aboveground pool to be semi-inground by excavating and partially burying the liner, for example, will only take three to five days, while installing an in-ground pool with a poured concrete liner and building up the land around it will require several weeks. Keep in mind that the process of hiring a pool contractor and applying for permits can add several additional weeks to the total timeline.

The number of gallons in your pool will determine how much chlorine you’ll need to add to your pool for the first time. Chlorine levels should fall between 1 and 3 ppm. It's crucial to read the instructions on your chlorine packet to determine the number of tablets to put in the water based on your pool's capacity.

Completely refreshing the water in an aboveground pool every five to seven years helps keep it free of bacteria and algae. Emptying the pool also allows you to clean, repair, or replace the pool liner. Schedule your water change when the weather is mild, as intense heat or cold can damage the pool liner when the pool is empty.

Costs range from $25,000 to $50,000, depending on size, design, and additional features.
