Customers say: Quality work

"????? Reliable, hardworking, and goes the extra mile Domingo with DM North Bay Pool Service has taken care of our pool in Kentfield for over a year and a half, and I can say without hesitation that he is one of the most patient, loyal, and motivated service providers I have worked with. He took on our pool when it needed a full startup ? initial deep cleaning, filter work, booster pump installation, and chemistry rebuild ? and got it dialed in quickly. From there, he handled monthly service consistently, communicated well via text, and always made time to talk through what the pool needed. When we had to pause service for several months while the property sat empty, the pool fell into rough shape ? algae bloom, heavy debris, neglected hot tub. Domingo came back without complaint, brought the right equipment, and restored the pool to swim-ready condition. He treated it like his own. That?s the kind of work ethic you don?t find easily. A few things that stand out about"

Customers say: True professional

"We hired McCormick to remodel our master bathroom, and the process couldn’t have been smoother. Khaled guided us through everything, and his team was skilled and respectful. They handled the job efficiently, stayed within budget, and kept our home tidy. Now, our bathroom feels like a relaxing oasis, with high-quality finishes and a modern touch we love. McCormick’s attention to detail really made the difference, and I’d gladly hire them for future remodels. This experience was everything we hoped for."

Pool and Spa Servicing FAQs, answered by experts

It’s easy to keep your hot tub clean and safe for all to enjoy by following a few simple tips:

  • Make sure anyone who uses the hot tub rinses themselves and their swimsuits off, perhaps in an outdoor shower near the hot tub. 

  • Don’t add anything to your hot tub’s water. Bath oils and bubble bath liquids might seem like a fun addition to your hot tub experience, but these substances will turn the water in your tub foamy and its surfaces hard to clean. 

  • Restrict eating in the tub to light snacks that you can easily clean out if there’s any spillage. Crumbs from crackers and chips can be difficult to pick up. 

  • Make it a no-pet zone. Pet fur and dander can pose a cleaning issue, but it’s also not a great idea for your pet’s health and safety. 

Most hot tub motors can last between five and 10 years; however, hot tub motors can burn out sooner if the hot tub water is not maintained or if the motors themselves are not maintained or protected from the elements. Since hot tub motors (also referred to as spa pumps) power the jets and circulate the water, they are important for the functioning of your spa. Buying a quality motor, keeping the hot tub filter clean, and keeping the wet end of the motor wet and the dry end dry can help them last longer.

Algae-related green hot tub water is generally safe to use, as algae aren't usually harmful to your health. However, if the conditions in the hot tub are hospitable to algae growth, they may also be hospitable to the growth of other types of microorganisms, including Pseudomonas aeruginosa, bacteria that can cause hot tub rash, or Legionella bacteria, which can cause respiratory illness.

Generally, it is more cost-effective and energy-efficient to leave your hot tub on all the time rather than turning it on and off. Reheating a hot tub from a cold temperature consumes a significant amount of energy, so maintaining a constant temperature is usually more economical, especially with frequent use.

For daily or weekly use, it's recommended to keep the water at a constant, reduced temperature, such as between 80 and 95 degrees Fahrenheit, and then increase it to your desired temperature before getting in. If you know you won't be using the hot tub for an extended period, you can lower the temperature to save on energy costs. However, if you use it very infrequently, you can turn it off completely, as long as there is no risk of the water freezing.

You should put chlorine in your hot tub on a regular basis. To keep bacteria away, keep the chlorine level in your hot tub at between 3-5 mg/l, which may mean you need to add chlorine daily or at least every two to three days. Don’t add chlorine to your hot tub water more than once per day.
