Customers say: Quality work

"If you are looking to resurface or refinish your pool, you have come to the right place! I have not had any pool work done in 20+ years, so it took a bit of investigating to find the right place. When I called Shamrock Pool Fiberglass, the owner Jan Moreno set up an appointment. He went into great detail regarding what it would take to make my pool look new again and better than before. My wife wanted the pool to look blue. He explained the fiberglass and the gel will be a bright white, but the color of the sky will make the pool look baby blue. We worked out a deal and I signed the contract. This was back in December 2020. He said all his people follow COVID-19 rules such as wearing masks and using a bathroom at another location (not at my house). The men were very nice about everything. If I had a question about something, they explained it, and we all kept our distance. The work that was being performed was something special to see. All of the work was done to my liking and very professional just as Jan Moreno said it would be. Jan even came on the last two days to spray the fiberglass in the pool. The pool resurfacing came out great and now the water looks baby blue! Our friends that come over just love the look of the pool and at night with the pool light on it is great. Many thanks again to Jan Moreno and his company Shamrock Pool Fiberglass."

"We hired McCormick for a bathroom remodel, and the whole process was smooth and professional. Khaled helped us make smart choices on design and materials that worked for both our budget and style. Now, our bathroom feels like a spa every time we step in. I appreciate the quality and attention to detail. These folks definitely know what they?re doing!"

Pool and Spa Servicing FAQs, answered by experts

If you want to have a chemical-free spa, or if you are wondering how to keep your hot tub clean naturally, there are several options. Some individuals choose to run their hot tub without treatment at all and simply clean it more often (although you risk bacteria, fungi, and algae growth if you take this route); others use natural products like vinegar or Borax. Ozone, ultraviolet light, and electrolysis systems are also eco-friendly ways to have a clean hot tub without chemicals. Saltwater hot tubs are popular with people who are sensitive to chlorine, bromine, and other traditional hot tub chemicals.

How often you change the water in your swim spa depends on how often you use it. Most manufacturers recommend changing the water every three to six months. If you use your swim spa throughout the seasons, it’s a good idea to set up a quarterly deep cleaning schedule. The ideal instructions should be in the owner’s manual.

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. 

In most cases, it is safe to clean a hot tub with vinegar. You will want to verify that your hot tub manufacturer lists vinegar as a safe cleaning product; however, given that vinegar is chemical-free, cleans, deodorizes, and is safe for people and pets, it is usually a good option. You can use vinegar to clean the hot tub shell, interior and exterior spa surfaces, hot tub jets, hot tub filter, and other parts. It is considered a strong, safe, and natural cleanser that can kill bacteria, remove mold and mildew spores, erase water spots, and remove hard water stains.

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.
