What Our Customers Say
Four years in and this pool still delivers on every promise made at the start. From the first consultation through swim day, the process was smooth and the crew was great to work with. They built exactly what we envisioned — the right shape, the right features, and a bubbler the kids love. When our pool light went out years later, they replaced it at no charge with a smile. Best decision we ever made.
I hired Ultimated Pools by Fetter and they did an amazing job!! My pool looks beautiful. Sargon and his crew are fantastic. Not only they built my pools with no issues and on record time. But also it was extremely affordable compared to the competitors. Am very happy with my pool and will recommend Ultimate Pools by Fetter to anyone! Thanks Sargon and Ultimate pools by fetter!
My wife and I are very happy we went with Ultimate pools by Fetter for our pool. We talked to a couple of other companies and were impressed by Fetter because they didn’t try to talk us into anything we didn’t want. They were patient with us during our design phase as we started out wanting a spa and water feature and then changing our minds to just getting a pool. At no time did they try to talk us into into getting a particular pebble finish or plaster finish for the interior. Ross was straight forward about what he thought would work best for us and told us the pros and cons for every decision we made. He was great at explaining the process and what to expect each step of the way. Once the pool was complete, they have been great at answering all of our questions about pool chemistry too! We would definitely recommend using them to put in your pool! We went with a French Gray plaster and love the way the water color turned out.
