"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."

"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"Great work and service by Eric, Ricardo and the crew. They went above and beyond with fixing the fireplace stone, power washing the patio, installing our grill, running the gas line from the house to the grill, and reporting the patio and stone wall. Highly recommend their service."

Pool and Spa Servicing FAQs, answered by experts

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.

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.

You can drain a hot tub very quickly by using a submersible pump rather than the hose-sized drain at the bottom exterior of the tub. A pump can move up to 30 gallons per minute, draining your hot tub in no time. Using the regular drain can take up to two hours.

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.

You should have your spa or hot tub inspected and serviced yearly to prevent more costly repairs. Regular hot tub maintenance can save money and help keep you safe from hazards such as faulty wiring. Call a professional hot tub repair specialist, who will know what common issues to look for and have the parts and tools on hand to fix them immediately.
