"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."

"Kevin is fantastic. He saved us thousands of dollars on an unneeded repair leak. Other pool companies told me it would be a week before they could get me but Kevin was their the next day. Kevin came back multiple times to insure the leak was fixed. Kevin fixed a pipe leak for free."

Pool and Spa Servicing FAQs, answered by experts

Hot tub heaters typically last seven to 10 years, though some might only last five years if not properly maintained. You can maximize your hot tub heater’s lifespan by ensuring the water’s pH level is properly balanced.

You should drain your hot tub three to four times a year to give it a thorough cleaning. This should take about an hour, but it depends on the size of your tub.

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.

Hot tub repair costs are less expensive than purchasing a new one, especially if your warranty is still intact. You can shop for a secondhand unit or find a deal for a trade-in. If the price to repair your hot tub is higher than the cost of a new one, consider replacing your unit.

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.
