"Working with Raul at Diamond Pools was truly a five-star experience. We were away on vacation during much of the renovation, and Raul went above and beyond to send us detailed daily updates with photos and videos so we always knew exactly what was happening. He even added thoughtful touches we hadn’t requested, all as a courtesy, and still managed to finish the project in record time to meet the aggressive timeline I gave him. His professionalism, communication, and dedication to quality set him apart from anyone else in this industry. The results speak for themselves: our pool looks brand new, and our backyard has been completely transformed. Raul and his team didn’t just renovate—they left everything spotless, even washing every piece of patio furniture and the floor with soap so the area looked “newer than new.” The craftsmanship, care, and pride in their work exceeded every expectation. Don't look elsewhere, call Raul. "

Braz Masonry handles all aspects of your brick paver installation, maintenance, and repair, also including, erosion control and pool coping.

"I typically do not deal with contractors as I do the majority of my home construction projects myself. Main reason for this is that I do not trust contractors and I feel there is the element of not getting the value for the money paid. Here's where Braz Masonry impressed me the most. Pool replastering is not something I would/could take on myself and therefore needed to get bids from different companies. Braz Masonry offered the best price and I decided to go with them, not only for the price but because I just got a good vibe from Roberto the owner. I was a little worried because I thought that, because of the lower quote, I would get hit with hidden extras to make up for the underbid estimate. The opposite actually happened. There was an unforeseen issue with my coping and there was an opportunity for him to make some extra money as I was already well into the project. Instead, I believed I got an extremely reasonable quote for this extra where I don’t think Roberto made any "

Pool and Spa Servicing questions, answered by experts

You can and should use a hose to fill a hot tub. There shouldn’t be anything special about the hose other than it shouldn’t be damaged. Kinks or leaks could slow down the filling process. Attach the hose to the nearest spigot and get the water flowing.

Shocking your hot tub means adding extra chemicals to the water. Most spa experts recommend doing this once a week for proper hot tub maintenance, but you can do it more if needed. Shocking has multiple benefits, including preventing the water from becoming murky and it’s essential in removing harmful bacteria from the water.

Using bubble bath, bath oils, bath salts, or moisturizing products that contain butters or oils can damage your jetted tub. Because of the water pump and jet mechanism, you need to be more selective with products for a jetted tub than you would for a traditional bathtub in order to keep it functioning properly and avoid expensive repairs. These products also leave residue that can feed mildew and mold, so it’s best to avoid them.

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.

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.
