read moreI live in Bethesda, MD and have been searching for a locally owned pool service company that has a wide-ranging set of support. My search is OVER! I cannot say enough about Twin Pool & Spa. The twins Derrick & Brent (yes, they really are twins) visited my home, saw my pool and said "let us handle this please." The rest is history! Our pool is now in good hands hopefully for a very long time. This is a family-owned and run business. When you call, ask for Martha (that's the mom) who is awesome too. I highly recommend Twin Pool & Spa!!

read moreTwin Pool & Spa is one of those service companies that you hope beyound hope you will run into in your life time.

I was in a bad spot in mid- August when my filter pump went out and my then pool service company of which I had been a cutomer for 23 years said they could not get out for two weeks. Reluctantly, I agreed to wait but asked if when they came to make sure they had the appropriate pump on their truck. They assured me they would. On Friday the day of the service call they came determined it was in fact the pump and told me it would be another four days at the earliest before they could return and fix the problem.

At this point I started calling around to find someone who could come out. Thank God I found Twin Pool & Spa they got the pump and came out on Sunday and fixed my pool. Subsequently I have swiched my pool services to Twin Pool & Spa. My closing in October was the smoothest least intrusive closing I have been through in 23 years.

read moreA pool heater or a pool heat pump are the most common heating solutions that allow you to maintain a continuous temperature in warm and cooler weather. Both enable energy-efficient heating for every budget. Brent and Derrick Marth have the manufacturer training to help you consider the various factors and recommend the best heating solution for your pool. A pool heat pump takes heat from the air and transfers it into your pool water. They are extremely energy-efficient to operate and deliver savings of up to 70% versus a gas heater.
Pool Pumps
read moreJust as an engine is the heart of a vehicle, the pump is the lungs of a pool. It's the key component of the filtration system that keeps your water clean. For installations, we recommend a medium head, variable speed, high efficiency pool pump, right-sized for your pool. The incremental cost of the variable-speed pump is now low enough that the transition becomes a no-brainer and the payback is quick. The DOE's Energy Conservation Standards for Dedicated-Purpose Pool Pumps sets July 19, 2021 as the deadline by which variable-speed pumps will become mandatory for powering pool and spa filtration systems.
read moreThe pool filter works with your pump to clear oil, debris, dirt, and algae spores as part of the filtration system. A high quality Pool Filter is the key to creating and maintaining a healthy and sanitary swimming environment. We typically recommend Cartridge Filters as they catch smaller dirt particles, clean more rapidly, require less pump pressure, and are easy to maintain. When purchasing a new Cartridge Filter, bigger is always better. We do not usually recommend DE filters or sand filters for an optimal sanitary pool environment.
