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"

Pool and Spa Servicing FAQs, answered by experts

Though a hot tub has many benefits, there are a few cons. Mainly, hot tubs require a lot of maintenance. You’ll need to deep clean yours quarterly, test the pH at least once or twice a week, and add sanitizing chemicals once a week. They also have relatively high ongoing costs since you’ll need to pay for electricity and repairs. 

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

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.

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.

Biofilm growth can cause a hot tub to feel slimy. Hot tub biofilm is a slimy substance that’s typically due to natural contaminants like makeup, soaps, skin oils, deodorants, or lotions. A hot tub can also have a slimy interior or slimy water if the tub’s filters are old or damaged, or if the hot tub isn’t properly cleaned. You should drain your hot tub, wipe away any slimy residue, then refill the water and use a spa purge product that prevents the buildup of biofilm.
