"Amazing Customer Service!! Taylor and Jacob both did a great job closing our pool this past year. Both of them were friendly and very knowledgeable with any questions I had. They texted me before showing up to close my pool and throughout the entire experience there was great communication which is very hard to come by. I 100% recommend this company. We are already scheduled for our pool opening this fall :)"

"I just had a three man crew move my hut tub today. They showed up on time, loaded everything including the cover, stairs and cover lift, and within minutes they were moving to the new house. They were very professional and friendly, and set up the hot tub exactly how I wanted it. The whole process was less than an hour, not including drive time. The pricing was exactly as quoted. I would highly recommend Two Men and a Spa Dolly."

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.

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

Most hot tubs will experience leaks due to wear and tear in the plumbing or the shell itself. The second most common issue is a heater malfunction due to the ongoing heat stress on moving parts. Finally, clogs happen in hot tub jets, especially when it’s time to change the filter.

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.
