"Watermark carried out all defined services professionally and thoroughly. I received proposal within 3 days after requesting one. The proposed cost and work coverage was better than others I had received. Nick came to the house once I requested a proposal and reviewed the pool area so that his proposed work would be reflective of all conditions of the pool. The overall work was carried out professionally and the end result left me with a 'new pool'. The pool is relatively large (20 X 45)- 31,000 gallons and I now have a pool that is something I am proud. Nick stayed on top of all work in progress and kept me informed of each step and what was expected of each step. There were no hidden costs or surprises during the job or at completion."

"This company is absolutely wonderful. We had a new vinyl pool/salt water system installed. They are professional and a joy to work with. Our pool turned out beautifully and would recommend them to everyone. We had a pool at our old house and the pool that Louis and Chris installed was just as great. We couldn't be happier."

"Dave (the owner ) was very prompt in responding to my request for an estimate, looking at my pool resurfacing issue, and providing his quote. His price was very reasonable compared to other quotes. His team worked very hard and efficiently. They completed the work in two days. I strongly recommend Allegro Pool Service for your pool needs."

Pool and Spa Servicing questions, answered by experts

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

Many people find saltwater tubs worth the upfront expense. They cost less to maintain than traditional hot tubs, so you can save in the long term. Maintenance is also easier, typically involving balancing the pH and cleaning the tub rather than adding chemicals. They’re also gentler on sensitive skin, and you won’t walk away with a strong chlorine odor.

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.

To refill a hot tub after winter, start by opening up the tub and giving it a quick cleaning. If you use antifreeze, drain out the water then grab a hose and thoroughly clean the tub shell out, spraying water into each jet of the tub. 

Reconnect the hot tub and turn the power back on. When it’s time to fill the tub again, insert the hose into the filter well (if available). Avoid trapping too much air in the water lines, which can cause the pump to lock up when it starts again. Add the necessary chemicals and start the heating process. It will take some time—most of a full day—for the water to heat up again.

Yes, they provide full-service inspections, identifying and resolving any potential equipment problems.
