"Greg and his team were excellent to work with. We put in a kidney shaped, gunite, salt water pool with a slide and a dive rock. It came out great. We use the team to open and close the pool each year too. We recommend Greg and team for your pool install and maintenance."

"Well, the first time the replacement was ordered it was the wrong one, which of course, delayed the installation a week. When it was finally installed I had to pay an additional $850 for code upgrades. This I was not informed of by Home Shield. Then we noticed that there was water on the garage floor and found that the pipe coming in from the wall was leaking at the wall so had to call the plumbing company back out to fix it. They first tried to say it was not their fault but since there wasn't a leak before they installed they did fix it. I have used Home Shield a few times before and never had a problem. Some of the companies they use are not the best so you have to research them before you commit. I have found HS service to be good if you do your homework. At the end of the day I was without hot water for almost 3 weeks but it was do to the plumbing company they sent out."

Pool and Spa Servicing FAQs, answered by experts

No. In fact, some owners prefer to “summerize” their hot tubs and use them primarily over winter to enjoy the contrast of cold and hot water. It’s possible to keep the tub filled and running year-round, and some pros may even recommend this method compared to the work and risks of a full winterization every year.

However, keeping the hot tub running will require additional resources. You’ll use more power and more chemicals to keep it in good shape. Weigh the pros and cons of your situation before making a decision.

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.

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.

If your hot tub is well-maintained, covered tightly, and the water is balanced and sanitized correctly, it can remain unused for up to two weeks without significant issues. Beyond this period, the water quality may start to deteriorate, potentially leading to the growth of algae and bacteria. However, it's crucial to note that this timeline can change due to factors like water temperature, sanitation levels, and the quality of your hot tub cover. Regular maintenance and water testing are essential to ensure the water remains safe and clean during periods of inactivity.

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.
