"Larry and his crew upgraded our under cabinet lighting with new LED lighting, and specialized outlet. Not only was our home and its contents treated as if they lived here, the job was done professionally. So much so, that the only issue we had was when the switch/outlet face plate screws came loose. I didn’t even bother calling Larry, I tightened them myself. The lighting is on, literally 24 hours per day since the install, with zero issues. Love these guys."

"My pool couldnt even be called a pool at the time an estimate was provided. The previous owner of my home atempted to turn a liner pool into a concrete pool and use kitchen tiles along the wall. Needless to say the base of the pool cracked, broke and I could literally see dirt. The service manager at Subcomm pools communicated their concerns and the quoted price along with their plan of action. They communicated consistently and always kept me abreast of what was going on. They are very courteous and will go the extra mile to ensure I was satisfied. They took the time to answer any questions that I had. They also directed me to reading material that assisted with the maintenance of my pool. Very courteous staff and hard working. They were in the heat of the sun and still kept driving on. I would bring them a pitcher of water and ice everyday and they were very grateful."

"The owner of this company serviced our pool for over 15 years.  He was extremely responsible and professional.  He always responded to my calls promptly and made whatever repairs were necessary as quickly as possible.  He was always sensitive to costs of replacement items.  He also spent the off season going to classes and manufacturer training to be current in the industry.  His rates were reasonable.   When we were remodeling our pool deck and pool, he coordinated with the pool and deck contractors.  When our heater needed servicing he was knowledgeable enough to conduct the service himself.  Our pool was always crystal clear.  If he hadn't cut back with servicing our area, I would still have his company service our pool. "

Pool and Spa Servicing FAQs, 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.

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.

Properly maintaining your hot tub will prevent serious issues from occurring down the road. You should replace the filter once a year, regularly look for and repair small cracks in the shell, and test the water quality every few months. You can do this yourself for less than $100 per year.

You can also hire a hot tub service to service your hot tub annually to identify problems early, which could save you money in the long run. They cost about $100 to $200 per call.

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.
