"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"Ricardo was meticulous and very professional. Work done was excellent and they attended to all details. They provided ideas to improve the project and helped me because the conscious. They cleaned up the area very well when they were done. Sod was installed in the areas that were dug up around the project. They gave me an update each day as to what was going to be done that particular day. Would definitely use them again and highly recommend them."

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Bob (the owner of BJs) even found me a replacement for my outdated fiber optic light which had not worked in years and had been discontinued by the manufacturers for years as well.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

When designing your dream pool, it's important to leave enough room for safe walkways, patios, and extras such as outdoor kitchens and fire pits. Your local building codes may specify the minimum space between your pool and your house, utility lines, and property line. In most cases, the area of the patio around the pool should be equal to or greater than the surface area of the pool.

A few factors influence the time it takes for a pool to heat up, including the size of your pool, the temperature outside, and how much direct sunlight is hitting the water in the pool. With these factors in mind, it takes 12 to 72 hours to raise the temperature in a pool by 20 degrees Fahrenheit.

While you can run a pool heater all day, it is advised only to run it during the day, as it is more energy efficient. At night, it is better to purchase a solar pool cover to retain the heat within the pool.

It can take 24 to 48 hours to fill a 15,000-gallon pool with a garden hose. A hose will pump out anywhere from 4 to 12 gallons per minute, with the average hose resting somewhere between 8 to 9 gallons per minute. If you want to speed up the process, a water delivery service can fill your pool in a few hours or less.

Once you use a pH decreaser, you can expect the pH to adjust in two to four hours. If you use a strong chemical like muriatic acid, it could take as little as an hour. Either way, it’s best to wait for a full turnover cycle before retesting. You want to make sure the chemical is completely dissolved and evenly distributed or you won’t have a stable pH level.

It’s best to avoid draining your pool onto your lawn for several reasons. Most importantly, your local municipality may not allow homeowners to drain pools in areas where it can seep into groundwater. Additionally, draining pool water on your lawn can cause erosion and damage your grass.
