My pool needed pretty much a rework of all the filtering and pump equipment due to age.

Contacted several companies for quotes.  BJ's was in the middle ground pricewise, but 2 of the companies were also sky high on their estimates.

These guys removed all the old equipment, put in a new concrete pad, & installed all new equipment.

They started on schedule and finished when they said they would.

Bill from BJ's did a great job and is very professional as is everyone else there at BJs.

Bob (the owner of BJs) even found me a replacement for my outdated fiber optic light which had not worked in years and had been discontinued by the manufacturers for years as well. Talk about finding a needle in a haystack!

Thanks to all at BJs for the great job!

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

A swimming pool pump has to have water in it to run properly. If the pump isn’t primed and tries to run when it’s dry, the components will overheat which can cause the pump to seize up and can even damage the PVC pipes that carry the water into and out of it. Essentially, running a pump that isn’t primed can lead to having to replace the entire pump.

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

If you want to get rid of an aboveground pool, one option is to hire a pool removal service to disassemble and dispose of it. However, you might also be able to sell it depending on the pool's condition and age, as well as the demand in your area.

When looking into fiberglass vs. concrete pools, you will notice a big price difference. A fiberglass pool costs $15,000 to $75,000, whereas a concrete pool costs $35,000 to $100,000. While concrete pools are customizable, fiberglass is faster to install and requires less maintenance. Additionally, you can expect to pay $25,000 to maintain a concrete pool over a ten-year span. On the other hand, a fiberglass pool only requires basic maintenance like testing water levels and cleaning.

Yes, it’s possible to put too much salt in your saltwater pool, and doing so can cause a number of problems, including corroding metal parts and causing the chlorinator to stop working correctly. In general, slightly elevated salt levels won’t cause serious problems beyond salty-tasting water, but you should dilute the water in a pool with extremely high salt levels to prevent damage to its components.
