"Water Mark Pools did an amazing job replacing our pool tile, regrouting, and recoating the pool to ensure there were no cracks or grout issues. The entire crew showed up every day, worked hard, and paid close attention to every detail. The quality of the workmanship was truly top notch, and the finished product looks absolutely fantastic. Customer service was exceptional from start to finish. Nick provided first-class service, he came out personally, explained the entire process clearly, gave us a fair price, and handled everything professionally. He also followed up with the company to coordinate filling the pool with water, which made the whole process seamless and stress-free. It’s hard to find companies this reliable, efficient, and professional anymore. I highly recommend Water Mark Pools to anyone looking for high-quality pool work! Patti Miller Chesapeake Beach MD"

"At first my experience with Dystempool was not good. I made an appointment for a Monday, waited at home all day and they never showed up. Tuesday morning I sent them an unhappy email. Nick answered it, apologizing that he was out of town and his technician had suffered an injury. He promised to get there that day. Nick arrived late in the day and worked all by himself into the night and did a very thorough job. He spent a lot of time clearing the line for my waterslide. I was especially impressed that he was able to install my Loop-loc cover all by himself. The next day I noticed he had replaced one of the cover anchors and didnâ t charge me for it; didnâ t even mention it. His fee was $100 less than my usual company charges and they couldnâ t get me in until November. I am more than satisfied with the work Nick did and I plan to hire him for my spring opening. This is the kind of hard working small business that America is famous for. I heartily recommend Systempool for your pool service needs."

"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."

Great, Two technicians showed up and began work. I was called in to view the original builders work. Really! My builder did not even have an electrical box to feed the lights just a wire. I was told some drywall would be removed to feed the wires for the 2 lights. OK.. Well they cut the wall ran the wires set the boxes and replaced the piece of drywall with the scraps. I now have 2 perfectly centered and level locations for my lights. They even left me some drywall scarps from the holes they cut to fill the hammer holes the original builder left.

A great job from a great crew. My wife loved the  sound of the Vac when they cleaned up whatever mess they made. I never saw the mess. Great! Great! Great!

I/m looking for more electrical work just to have them back.....

"My pond is the healthiest it's ever been, I don't know if it's because of backyard ponds, or whatever? But I now have baby fish about 12 of them and I am going to hire them to do my winterization. I got a very professional reminder from backyard ponds in the mail today, and I really appreciate the reminder. Sometimes things like this slip your mind, but it's very nice that they remind you that winter is coming up, and you need to plan for the future. My fish are not expensive, because this is a newly renovated pond. But I'm very happy with the job that they did, and I will recommend them in the future. And I will be using them very soon"

"Thanks again to Hydro Pool for another great year. As always these past 10 years, George ensured last week's pool closing and cover installation went smoothly. Kudos to the service department, including those like Dave who always answer my calls in a friendly manner and make scheduling hassle free. Thanks again, until next year's pool opening Hydro Pool!"

"Called about leak Sunday morning. Plumber came out Monday, determined it needed replacement and notified Choice, who approved claim and permitted plumber to order new water heater. Thursday new water heater was installed. Was kept updated every day by both Choice and the plumber. Workers left my garage clean and I have hot water. Very satisfied and have recommended Choice Home Warranty on the Nextdoor app."

FAQs for swimming pool heaters installation and replacement projects in Ellicott City, 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.
