"This is our second time hiring WaterMark Swimming Pool Service, and once again, they did not disappoint! This most recent project was more extensive, as we needed our pool completely replastered. Not only was WaterMark’s quote thousands of dollars less than other companies, but their team was also professional, fast, and extremely efficient. Nick and his crew did an amazing job from start to finish. They had our pool completely finished and back up and running in just a week and a half! We couldn’t be happier with the quality of their work and the overall experience. If you’re looking for a reliable, professional, and affordable pool company, we highly recommend WaterMark Swimming Pool Service! ⭐⭐⭐⭐⭐"

"Had a pool liner replaced and what a GREAT EXPERIENCE!!! From Sara and Christy in the office to Mike, Gavin and Yoti of the install crew. Just a fantastic group of professional, knowledgeable, hard working people. The girls went above and beyond in researching the correct liner and supplies that I needed to provide and the install crew weathered a 100 degree heat factor and provided the ultimate install. Refreshing to experience genuine A-1 customer service. Pardon me if I have any names misspelled. I sincerely appreciate the fantastic effort of everyone involved!"

Pool and Spa Servicing FAQs, answered by experts

When your hot tub is completely dry, there is typically no need to introduce antifreeze into the plumbing. However, if you desire an extra layer of protection against potential freeze damage, you can consider adding some RV antifreeze to your hot tub lines. Just ensure that you use RV antifreeze specifically, as automotive antifreeze is highly toxic and should be avoided.

Hot tubs don’t necessarily add value to a home—but they don’t take it away either. It depends on the potential buyer. A well-landscaped in-ground hot tub is attractive to buyers who prioritize relaxation and fun. Others would rather not deal with the maintenance. 

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

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.

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.
