"I needed a total re-plumb of my in-ground pool and talked with a few companies. Andrew from Bay Side was extremely courteous and answered all my questions. His price was very fair so I decided to go with them. I was very concerned about the destruction to my landscaping. Andrew's team did the job with surgical precision and I ended up not losing one shrub and minimal damage to the lawn. I will be using Bay Side from here on out for all my pool needs."

"I had a great experience with this company. From my first conversation with the owner, they were friendly, honest, knowledgeable and incredibly helpful. They took the time to answer all of my questions and were very transparent throughout the process, which I really appreciated. I originally reached out because I needed help putting together a new above-ground pool, but a family member ended up doing the installation instead. Even though I didn't become a customer, I was impressed by the professionalism and excellent customer service. Based on my experience, I wouldn't hesitate to recommend them or use them for future repairs when needed. Highly recommend"

Install Above Ground Pools FAQs, answered by experts

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.

The formula you’ll use to measure your pool will differ based on the shape of your pool. For a rectangular pool, you’ll use the following formula to find the size in gallons: length x width x depth x 7.5. If the depth changes from one end of your pool to the other, take the average by finding the depth at the deepest and most shallow points and dividing that number by two. Circular and oval pools require different, more complicated formulas, which can be found in this article.

You shouldn’t swim in a pool with algae. When there’s algae, there’s also bacteria that’s feeding on the algae. Also, algae-infested pool water is often chemically imbalanced, which means germs like Cryptosporidium, Giardia, and E.coli could be present. These germs can cause a range of illnesses from gastrointestinal issues, to rashes, and respiratory problems.

The best thing to do is to get rid of the algae first, test and balance the water, and then you can enjoy swimming without any worries.

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.

A pool builder can advise you on the best design for your property and vision, and can walk you through the process from design to a swim-ready pool. Knowing which questions to ask a pool builder can help ensure you choose the right person for the job.
