I am very happy with the work American pools does. I had them replace my liner last year and it came out beautiful. I had them close my pool, they did it on time and well. I just had them open my pool last Thursday and this is where I am most pleased. I have a safety cover on my pool that allows water through and every year it opens green. When I hired them to close my pool I asked if there was anything I can do to prevent the green. The kid told me there are some chemicals that can help prevent the green. They did it, and for the first time in 7 years my pool opened clean. This company does very good work. I strongly recommend them.
