I absolutely love my new pool and spa. It is gorgeous. What a transformation! My yard went from ugly and disgusting to beautiful and relaxing.

I met Greg at the County Fair and liked him immediately. He wasn't a pushy salesman and knew a lot regarding their pools. I wanted one but unfortunately, I had to wait. Two years later, yes two years later I still wanted my pool and called Greg. He had the same number and agreed to meet at the County Fair ( the deals are unbelievable during that time). I left the fair a few hours later a proud owner of a new pool, jacuzzi with a gazebo and bar.

The crew broke ground on Oct. 24th 2019 and they were completely finished by Jan. 24th 2020. Chris was my contact person in the office and he was nothing but professional the entire few months. We had a few hiccups but nothing major and the small issues were corrected immediately.

Thanks Secard Pools for my beautiful backyard.

Everything about my experience with Secard Pools & Spa's has been positive.  From the front end, where Rachel, Edna and the entire sales team in the Orange County Store made me feel welcome and answered my questions... to the delivery team coordinated by Chris and consisting of Jason, Carlos, Michael, Jesus, and Hector; the Seacard team is as customer focused as they come.  Because of some problems finishing the rehab on my house, I asked Secard to store my spa for a couple of months.  They were very gracious and professional... and easily scheduled the delivery when my slab was poured and ready to go.  I would use them again and again!  Keep up the great work!

I highly recommend Secard Pools in Hesperia. I was lucky enough to get out of an agreement with Lifetime Solutions, and was very hesitant to enter in to an agreement with any other company selling spas. Laurie at Secard is amazing! Talk about no pressure sales! The only questions she asked us was about our preferences and what we thought we might want, and then she showed a number of different products.

There was never any pressure and after we did select a spa and gazebo, the set up was quick and efficient and very clean. We received our products in a reasonable time. We got an excellent price on both the Cal Spa and the beautiful gazebo.

Do not make a decision about buying a spa without first going into Secard Pools and Spa. You will be doing yourself a disservice if you ignore this advice. I am now a very enthusiastic and satisfied customer.

Thanks for the awesome spa, Laurie. And thank you to the three gentlemen who set it up; you are fast, polite and efficient!

After buying our new home we knew we wanted a swim spa for our enjoyment, relaxation, and entertainment with family and friends. After doing some online research I went to our local Secard Pools and Spa. The guys there were amazing to work with. It was low pressure and they had the spa I wanted. We coordinated with delivery and set up and they're very flexible with their time. Over the past two years I've had nothing but the best help and service with them. I still buy all of my supplies from there and enjoying paying them a visit and saying hi.

We were looking for a new spa this year and after much research and many trips to the show room to ask only about 99 questions, Jeremy always was polite and had great knowledge of all the spas. True old school customer service . A real customer first salesman. We are truly thankful for all of your help. Great delivery team. Was on time and placed the spa right where we wanted at. We have no complaints.
