"After other businesses failed to respond to my requests for help, Commercial Pool & Spa was prompt to respond. It got better from there. Both the office representative and the service technician communicated effectively by phone and text. The tech visited within hours, reviewed the site, quoted the work, and scheduled work for the following day. The tech was delayed but communicated by text to keep me informed. The work was started and completed in a timely manner. The spa now looks fantastic, and I am extremely pleased with the results and the overall experience provided by this service. I'll use them again and can recommend them to others."

"Wish I could receive this kind of customer service from all companies!! Professional, courteous, dependable, easy to work with. He replied to my repair request in a very timely manner. His prices were very reasonable. After the diagnostic, he ordered the needed parts and had my spa repaired within just a few days. So pleased I am now having his business maintain the chemicals in our spa. Very down to earth and easy to work with. Highly recommend him!!"

"Absolute Pool Resurfacing did a fantastic job. I had interviewed 3 companies to resurface my pool and I definitely picked the right one for the job. They are the best..The work was done professionally and in a timely manner. The price was very fair. We also had tile work done on spa wall and coping repair, also had them back to clean entire pool and spa tiling and it looks like a brand new pool.. if you want it done correctly Noe,Chris and his crew are the best.. I highly recommend this company"

"Scott just came out to service my pool heater, which wasn't working. My pool man said he didn't know why the heater wasn't working and to call a professional. I have been paying my poolman to clean my pool filter every other month. Scott came out and in seconds diagnosed that the pool filter was very dirty, needed cleaning and that's why the pool heater wasn't working. In less than 1/2 an hour he cleaned the filter and had the heater up and running! Obviously, I need a new poolman! Another plus: Scott came out and then gave me the estimate, vs. 2 other firms, which both mentioned $$ up front before coming out and assessing the situation. One of these companies quoted $430 to come out and repair the heater, sight unseen - unbelievable! Scott is professional, reliable and extremely honest. When I need pool work, he's the one I am turning to, without a doubt. Thanks so much, Scott!"

"Encore Builders did an amazing job with our pool remodel. The project included new plaster, waterline tile, coping, and upgrading the pool lights. What stood out to me was their professionalism, they communicated clearly, gave us realistic timelines, and delivered on them. The crew was polite, worked hard, and left everything tidy. When we finally filled the pool, the transformation blew us away. The water sparkles, and the whole backyard feels like a private oasis now. If you?re thinking about remodeling your pool, I wouldn?t hesitate to recommend Encore Builders!"

Pool and Spa Servicing FAQs, answered by experts

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.

Similar to a hot tub, swim spas last anywhere from five to 20 years, depending on quality and your attention to maintenance. The best way to increase the lifespan of your swim spa is to carefully maintain it—including draining it around every six months to deep clean the parts.

Yes, but only if it is a freshwater tub (not saltwater) and if you make sure the chlorine and bromine levels are below 1 ppm.

Follow these general safety tips for spas and hot tubs:

  • Keep your exterior electrical receptacles covered and dry, especially around your hot tub and pool during periods of use.

  • Make sure you have a GFCI (ground fault circuit interrupter) properly installed to ensure no one gets accidentally shocked or injured by electrocution. 

  • Don’t use the hot tub or your pool during a thunderstorm. 

  • Before using the hot tub, have a certified electrician thoroughly inspect your hot tub and its wiring to make sure you’re in full compliance with all applicable local building codes. 

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.
