"John from Clearwater Spa Company was very responsive to our home improvement job inquiry. After he found out that our Jacuzzi hot tub would be too old to replace the parts and be worth the money, he advised us to simply replace the Jacuzzi tub with a non-jacuzzi one and hire a local plumber to get it done. We greatly appreciate his detailed suggestions and very helpful consultation. Additionally, he explained to us all of the detailed diagnosis in great patience and truly put the customer first."

Born from a simple idea: the world's healthiest cultures don't just chase wellness — they live it together.\n\nCape Sauna Club is not an attempt to copy Norway, Japan, or Germany and drop it onto Cape Cod. That would miss the point entirely. This is about taking the essence of what makes those traditions so meaningful and shaping it into something that feels right here, on the Cape.\n\n"I'm not going to pretend we built something identical to what I found in those places. We didn't. We're on Cape Cod. We're in a barrel sauna, not a century-old Nordic longhouse. But the thing underneath it — the reset, the silence, the connection — that's exactly what we're bringing here."

"My original contract with O Donnell Pools was 2 years ago to have them remove all tiles, resurface and paint my gunite pool and install all new tiling. When they completed the work the 25 year old pool looked brand new. I then contracted with them for opening, closing and weekly service and have been extremely pleased with the services provided."

Pool and Spa Servicing FAQs, answered by experts

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

Hot tub repair costs are less expensive than purchasing a new one, especially if your warranty is still intact. You can shop for a secondhand unit or find a deal for a trade-in. If the price to repair your hot tub is higher than the cost of a new one, consider replacing your unit.

The best thing with which to clean a hot tub is whatever the manufacturer recommends; in most cases, this is a gentle surface cleaner and a soft cloth. Recommended hot tub cleaners can include specially formulated cleaning agents, mild dish soap, baking soda, vinegar, or diluted bleach. For your hot tub exterior, choose wood or vinyl cleaner (depending on the casing material).

You should never use household cleaning products, harsh chemicals such as undiluted bleach or acids, or abrasive cleansers or cloths, as these can scratch or etch your hot tub’s coating or shell and cause permanent damage.

Yes. If you test the water and the alkalinity is too low, you can raise it by adding an alkalinity increaser, which likely came with your hot tub’s chemical kit. In a pinch, you can use baking soda to raise the hot tub’s alkalinity. Raising the alkalinity will prevent the hot tub water from becoming too acidic.

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.
