"Watermark carried out all defined services professionally and thoroughly. I received proposal within 3 days after requesting one. The proposed cost and work coverage was better than others I had received. Nick came to the house once I requested a proposal and reviewed the pool area so that his proposed work would be reflective of all conditions of the pool. The overall work was carried out professionally and the end result left me with a 'new pool'. The pool is relatively large (20 X 45)- 31,000 gallons and I now have a pool that is something I am proud. Nick stayed on top of all work in progress and kept me informed of each step and what was expected of each step. There were no hidden costs or surprises during the job or at completion."

"Wound up getting in touch with this guy on a lark through home advisor the day he started on here. Has great reviews on thumbtack. Give him a call, set some stuff up and he was able to come out in the dead cold and wind to do the diagnosis. Got the parts, about a week and a half later he showed up in a little better temperature and got everything taken care of. Pro seemed very fair, seemed to be very knowledgeable. Would definitely call them again for issues with my hot tub."

"C&D were really impressive. I had used them some years ago and (through no fault of theirs) I had to install a new liner. They came out promptly, did the work in a timely manner and I was swimming again once the pool had been refilled. I would heartily recommend them to anyone who needs any kind of pool work done."

"This is the second time that Dig M Pools did and installation for us. Again we were very happy with the job they did. We purchased our pool from them and it is a well made product. The owners wife was very helpful when we were deciding what pool to purchase. I would recommend Dig M Pools as first choice. Excellent job. Thanks Dig M."

"Happy with pool surface...mini-pebbles with glass beads. Weekly maintenance during pool season since 2016. Paul and his team are professional, courteous, caring, hardworking and kind. Paul even came over on Labor Day weekend when our pump was not working...now that is above and beyond! Paul really cares about his clients and their satisfaction. Prices are fair and comparable. The water is always crystal clear and thankfully no one has ever gotten sick from swimming in our pool. Thank you, Paul and VIP Crew!"

FAQs for swimming pool heaters installation and replacement projects in Upper Marlboro, MD

Yes, you can add a heater to an existing pool. A pro can retrofit a heater to nearly any in-ground or above-ground pool. Adding a heater allows you to start the swim season earlier, finish it later, and maintain a steady water temperature in between. Many owners schedule the job during a larger pool upgrade, but it also works as a standalone project. Professional installation ties the new unit into the existing pump and plumbing for safe, efficient operation.

Most owners switch the heater on a day or two before they plan to swim, then shut it down afterward. Reaching the target temperature can take 24 to 72 hours, depending on pool size and outdoor conditions. Using a cover while the heater is off helps hold the heat and keeps energy costs in check.

Pool heaters can freeze if left exposed to extreme conditions. Freezing can damage internal heater components, potentially leading to costly pool repairs. Cycling water, covering the heater, and regular maintenance help prevent freezing. Sealing or winterizing your heater also protects it during the season—this involves draining water from the heater and its components.

Pool heaters operate with lifespans spanning from seven to 30 years. Gas and propane models last seven to 12 years, while electric and solar heaters perform efficiently for up to 30 years. Consistent professional maintenance and routine inspections extend the heater’s life and improve its performance, ensuring a safe and reliable heating system for your pool.

Before hiring a pool heater installation contractor, conduct thorough research by reviewing online feedback and gathering recommendations from trusted sources. Contact multiple professionals to discuss pricing, request references, and understand the complete installation process. This careful evaluation ensures you select a qualified contractor who delivers high-quality service and a successful installation.
