"I hired this company to close my pool over the winter. They were kind enough to come and take a look at my pool while I was trying to get it together for the summer. They were kind enough to give me some tips on what to do to get my pool looking sparkling clean. They are very nice and I would highly recommend their services! I'm glad I found this company! Thank you for your time!"

Pool and Spa Servicing FAQs, answered by experts

Hot tub repairs cost between $200 and $500 on average. You can minimize those costs by maintaining your hot tub and keeping necessary supplies on hand. An elevated shelf in the garage is a great place to store your water care chemicals so that kids and pets will stay safe and you’ll always have them around. 

Your hot tub should be drained of existing water, cleaned, and refilled every three to four months at a minimum. Follow your tub manufacturer’s recommendations for cleaning, and rinse thoroughly when finished to eliminate any residue from the cleaning products. This is also a good time to inspect your tub’s cover in good lighting for any leaks, tears, or other damage that might cause problems. 

Using your hot tub manufacturer’s suggested cleaners and methods, keep your hot tub filters clean to avoid a loss of water heat. This will help extend the filter’s useful life and efficiency. If the filter is more than two to three years old, replace it with a new one and buy a second filter to keep around as a spare.

Vinegar can be used as an all-purpose cleaner for many things, including hot tub filters. Soaking hot tub filters in vinegar and water for up to 24 hours can remove dirt and oil, and as a bonus, it won’t cause the water to foam after you reinstall it if there’s vinegar left on it. But make sure you still rinse it to remove any debris, dirt, or grime stuck on it.

A hot tub cover's lifespan is typically between three and seven years, with an average of five to seven years for a well-maintained one. The quality of the cover is a major factor; lower-quality polyester or vinyl soft covers can tear easily with regular use.

To extend the life of your cover, proper maintenance is key. This includes:

  • Keeping the cover clean, dry, and out of the sun. Use a soft cloth and mild dish soap for cleaning.

  • Applying a vinyl protectant spray.

  • Cleaning the underside with a chlorine spray.

  • Using a cover lift to prevent damage from rough handling.

  • Protecting it from harsh weather.

  • Keeping children and pets off the cover.

Investing in a high-quality cover and checking for a warranty at the time of purchase can also contribute to its longevity.

You’ll know you need to replace the pump in your hot tub if you hear loud or unusual noises when the machine is running or notice a significant decrease in water pressure. A leak or altogether failure of the hot tub may also indicate a problem with the pump, but you’ll need a professional to investigate the source of the issue.

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.
