  • I would recommend this business

We switched Pool Services last season: very inconsistent cleaning from a large Gaithersburg Pool Service. Brent and Derrick Marth offer the advantage of consistent service, high standards and diligent attention to the details of water management. I recommend the twins of Twin Pool!

From Our Website

Twin Pool and Spa wants YOU to attain the quality pool experience YOU desire. By asking what you want and showing you what is possible, we provide that poolside lifestyle of your dreams. Our swimming pool company logs photos of your pool and equipment to help eliminate problems before they occur, minimizing down time and cost. We analyze your pool and equipment, recommending only what is best for your needs. Your pool is personal. So is our service! Extend the life of your pool mechanics by improving efficiency and reducing your Spring 2021 down-time.


There are different types of pool service companies. Some are retail chemical and equipment companies that also service pools. There are pool builders who also service pools. Finally, there are those who try to do it all. The Twins of Twin Pool and Spa saw a need to perform service and repairs exclusively in a truly professional manner. We fill the void for homeowners who want pool service and attention to detail unmatched by other companies. Our mission is to provide superior service that allows you to relax and enjoy your leisure time.


A 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.
