"I was very happy with Anthony. He messaged me his eta, looked over my pool, was thorough and found some issues I was not yet aware of. Unclogged my pool line and gave me some very good tips that I plan to put to use/work on. I do plan on calling Anthony for any of my future pool/spa needs"

"Pool resurfacing as done quickly and cleanly. Price was better than others. They were very happy to explain the steps to me and did great work. The only reason I did not give them 5 stars is because their communication are lacking. They were not great at keeping me informed of their schedule. I had to email them a number of times to find out when they were coming."

"Greg was on time for the first appointment. He demonstrated knowledge of pool maintenance during our discussion. He then cleaned the pool and added chemicals. Greg returned the following day to replace a broken part for the purpose of re-installing the pool vac. I feel confident that he will provide the service to which we agreed."

FAQs for pool construction and installation projects in Thornton, CA

While it is possible to put a pool on a concrete slab, it’s not recommended. This can damage the liner of your pool and creates a rough floor that’s not pleasant. Professional installers use a sand base to create a level surface and ensure that your pool floor is comfortable.

Sand is a fine material that creates a smooth bottom for your pool. Other materials, such as dirt, could contain rocks that damage your pool liner.

Pool sand is also known as mason sand. The different types include concrete sand, yellow mason and white sand.
