"Amazing work and amazing service! Alvaro did an excellent job installing my swimming pool pump. He is very knowledgeable about electricity and went above and beyond by repairing the entire electrical panel as well. Everything was done professionally, safely, and with great attention to detail. I highly recommend Alvaro for any electrical or pool equipment work!"

"Diamond did an excellent job. Arrived on time, worked efficiently, high quality for the price. Replaced our spa, raised it and built a beautiful stone and tile wall around it. Replaced heater, filter and liner. Pool looks brand new. Even arranged for water delivery the day after liner went in. Good communication throughout."

"Our sales woman Lucia was very helpful and supported us through the entire process. Timing was an issue because of a party we had after being promised a finished date and it couldn’t happen. The distributor was blamed for being backed up on delivering our liner… then the installer promised to be done by Thursday so we could fill and put chemicals in Friday and it wasn’t done until Friday. So we made it by the skin of our teeth. Just didn’t appreciate the installer knowing the time line and promising it, then not standing by his word. It was weird. Liner is beautiful but there is a spot that is pulling and you can see a gap. I hope this won’t cause any future issues."

Pool and Spa Servicing FAQs, answered by experts

For a fully-foamed hot tub, freezing typically occurs when the temperature drops below 28 degrees Fahrenheit and remains at or below this level continuously for a minimum of 36 hours. If your hot tub and pumps are still operational, however, the water circulates, and this continuous movement helps prevent freezing, even in very cold conditions. This circulation, along with the insulation provided by the foam, helps maintain the water temperature and prevent it from freezing during extended cold periods. Still, if you’re not planning to run it regularly, be sure to winterize the hot tub properly to prevent damage from freezing.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.

Whether you can repair a hot tub depends on the severity of the problem and the location. With the right tools and knowledge, you can fix problems like small leaks or switching out a dirty filter. However, electrical and plumbing issues require a licensed professional due to the inherent risk, particularly when mixing water with electricity.
