"Our pool is 35+ years old. Watermark Pool Services updated our pool with new tile, new coping and new plaster about 10 years ago. This year, we needed a few repairs, plus my husband always wanted sky blue plaster. This company's work crews are knowledgeable, efficient and courteous. I wouldn't want any other company but Watermark doing the work on my pool! We absolutely love our "new" pool and the blue plaster looks amazing!"

"This company is absolutely wonderful. We had a new vinyl pool/salt water system installed. They are professional and a joy to work with. Our pool turned out beautifully and would recommend them to everyone. We had a pool at our old house and the pool that Louis and Chris installed was just as great. We couldn't be happier."

Pool and Spa Servicing questions, answered by experts

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.

Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

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.

Regular water testing, filter cleaning, and chemical balancing are essential for keeping water clean and equipment functional.
