Welcome to Gibraltar Pools & Spas. If you live in New England or Eastern New York, you have probably seen a Gibraltar Pool. From the Long Island Sound to Mt. Katahdin, from the Adirondacks to Cape Cod, chances are, there is a Gibraltar Pool in your neighborhood. Our years of experience, and our family-owned leadership in the New England swimming pool industry, are the key reasons for you to own a Gibraltar Pool. We feel you must buy from someone you are willing to be "married" to for a long time. We make a good lifelong partner.What we need prospective pool buyers to know is: WE ONLY INSTALL POOLS PURCHASED FROM GIBRALTAR POOLS WE DO NOT INSTALL OTHER TYPES OF POOLS. OUR POOL IS A RECTANGULAR ONGROUND POOL. WE DO NOT SELL ROUND OR OVAL ?TIN CAN? STYLE POOLS.

"I have had the best experience with Gibraltar, and I cannot say enough about the people who work there and the product itself; we love our pool!! Itâ s given us a lot of joy this summer with friends and family. But foremost for my review is the people who I have interacted with since we purchased the pool in the summer of 2020- they are awesome. Really the best. I have not seen customer service like this at another company in a long time. We put in our new pool last November for a deeply meaningful reason for our family and I ended up talking with the CEO and shared with him the reason. He was so awesome and wrote me such a sincere, kind, and genuine note. From the CEO to the college kid on the floor and everyone in between- I have been so impressed with their patience, knowledge, friendliness, and professionalism. Iâ m so appreciative to Peter, Ellen, Grace, Ana, Jason, Keith, Jim, Ryan, Wayne and Jim. They have all been so incredibly awesome to deal with, and I feel like I am working more with a family than a huge company. Itâ s amazing they employee so many people who are each individually so helpful. You can tell the owners really care about how their store is represented and that they care about the quality of their work. We (like several other families) decided to build our pool during quarantine in 2020. There were delays that no one could have foreseen because the supplies were impossible to get for months- but that was no oneâ s fault, no one could have guessed we would be in a pandemic, and that the demand for pools would go up so much. So, even though there were delays, we understood, and Gibraltar did everything the could to get our pool built as quickly as possible and to make sure it was open for the summer season of 2021- and it was. I was sad to see reviews that said they took too long- I honestly just donâ t think it was fair. Who could have foreseen the impacts of a pandemic? So, for us, the delays were what they were, and we appreciated that they did all they could, with what they had to work with, and kept up updated along the way. I would highly recommend Gibraltar to anyone who wanted to put in an awesome above ground pool and have superior customer service."

Heavenly Heat Infrared Saunas are made for the chemically sensitive. That means that our infrared saunas create an ideal, safe, and effective detoxification environment for anyone seeking to eliminate toxic substances from their body.

"Terrible! Wish I had gone with another company. Here is the issue with Heavenly Heat. If your sauna arrives damaged or and issue arrives -- they have zero technical support. Your repairs will be done by any "joe" that heavenly heat finds to do the repair in your area. They will have no experience with Sauna's and are given no instructions regarding the chemical free aspect of these sauna's. The worst part is the buyer, me, was treated as if I was the problem for wanting my sauna repaired correctly. I would have refused the delivery had I realized I was receiving a damaged sauna and would have to spend hours and days trying to get this resolved. The owner, Bob Morgan, is extremely responsive before he has your money but after, is a different story. When inquiring about the sauna he would respond generally within 10 minutes. After you purchase, and particularly if you have a problem with it, you are treated as if you're a nuisance. My sister bought a competitors sauna around the same time and the service she received from knowledgable representatives was a world of difference from my experience. My other issue was that there were shipping delays and Bob would never communicate them. I would have to pursue him to get information. I think they make a decent sauna but I would not recommend for reasons stated above."

Pool and Spa Servicing questions, answered by experts

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.

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.

It’s easy to keep your hot tub clean and safe for all to enjoy by following a few simple tips:

  • Make sure anyone who uses the hot tub rinses themselves and their swimsuits off, perhaps in an outdoor shower near the hot tub. 

  • Don’t add anything to your hot tub’s water. Bath oils and bubble bath liquids might seem like a fun addition to your hot tub experience, but these substances will turn the water in your tub foamy and its surfaces hard to clean. 

  • Restrict eating in the tub to light snacks that you can easily clean out if there’s any spillage. Crumbs from crackers and chips can be difficult to pick up. 

  • Make it a no-pet zone. Pet fur and dander can pose a cleaning issue, but it’s also not a great idea for your pet’s health and safety. 

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.

Most hot tub cracks can be repaired unless they have gone beneath the acrylic. If so, you may need a professional to determine if the crack is repairable or if you should consider hot tub replacement instead.
