"BEWARE! I had an inground pool and spill over spa installed this summer. The project in question stretched painfully over four to five months despite timely payments, raising initial concerns about the contractor's management skills. It appears the contractor, Carlos, simultaneously juggled multiple projects--likely in an attempt to secure more business--which translated to delays and compromised focus on this particular job. After the pool's completion, I discovered a variety of defects requiring repeated repairs. These included bulging and loose liners (3x) just one week post-install, plumbing problems, excessive leaking from the pool heater, and untidy workmanship such as messy silicone application around corners and stairs. What exacerbated the situation was the contractor's poor customer service. When approached for assistance, Carlos responded with rude behavior and a lack of professionalism. Instead of honoring the warranty he advised to go on youtube. Do not use"

Pool and Spa Servicing questions, 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.

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.

Properly maintaining your hot tub will prevent serious issues from occurring down the road. You should replace the filter once a year, regularly look for and repair small cracks in the shell, and test the water quality every few months. You can do this yourself for less than $100 per year.

You can also hire a hot tub service to service your hot tub annually to identify problems early, which could save you money in the long run. They cost about $100 to $200 per call.

Hot tub maintenance can cost between $240 and $900 annually. These costs include deep cleaning the tub, refilling the tub several times a year, and keeping the water's chemical balance. Keeping up with regular maintenance and cleaning tasks can help to keep your costs down, as you'll avoid more complicated and expensive repairs.

No, you cannot clean your hot tub filters in the dishwasher. While it may seem like a good idea, the dishwasher soap isn’t gentle enough for hot tub filters and can damage them. Gentle cleaning is better when cleaning the hot tub filters and keeping them intact.
