"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."

"Hands down System Pools is the BEST pool service in the area! In the past 7 years we have used three other pool service companies with System Pools being the 4th. Their price is very reasonable considering the high level of customer service they give and the great job they do on keeping our pool crystal clear. For years we had to top off the water in our pool every other week. We were told it was because the water evaporated. Nick came in and immediately told us that a crack in our skimmer needed to be replaced which was done in 24-hours. Since then we have not had top off our pool, not once. The new skimmer saved us hundreds on our water bill! My advice- don't use those big pool companies who really don't want to provide pool maintenance, but want to charge you big money on repair jobs. Use System Pools they will take great care of your pool!"

"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."

"This is the 4th year we have hired G Pro but the first year we used them for painting. They did an excellent job painting our shutters and porch trim. The price quoted for the services were reasonable and the quality of painting was excellent. Don’t hesitate to hire G Pro. The quality of their work is superior. Scheduling was easy and Ricardo and Eric are friendly and accommodating to your budget."

"I have a fish pond in the backyard with a water fall and it was in desperate need of repair. It was not done properly and had a lot of erosion so I had them redo it. They did a really nice job. I really liked them. They were there when they said they would be there. I don't know about the price, my husband does. I feel like I can call them up if there's a problem. They are really attentive. I got two different estimates and they came in at roughly the same price. I've been happy with them. It's a woman owned and it was kind of neat as far as I was concerned. I grew up in that Beltsville area so it was nice to have somebody from the neighborhood and a local girl do a good job for me. Her recommendations were very good. They ran into more trouble than they thought they were, but they dealt with it. They didn't expect to find this concrete in the soil. I don't know if it got there from the guy who did the pond work a while ago or it was in the soil from way back even before we moved here. It was like a big surprise and not a pleasant one because it was a lot more work to do. They were excellent. I only had two different prices and they were both very similar. I liked these folks better. They were very responsive and very professional. I would use them again in the future. I just called them a little while ago about doing a pond clean up in the spring. I'm going to watch how they do it and try to do it myself next year. I trust them and believe that they don't make me pay for something that I don't need. They are also good at giving advices. I can just call them and get advice. I had my heater go out in the middle of the winter and that I had fish in there so I didn't want them to die and I got some advice. They may have all died, but I got some advice about that."

"They have been out for the electrical. They have been out for the pool. They have been out for the sump pump. Its the fee for the service call. We have used them for the last 3 years. If you have an appliance that you think needs replaced they will not replace it they will repair it to death. They are very responsive. Some of the people they send out are great, some are okay."

"Let me start off by saying, we have had some very bad experiences with swimming pool companies, however, the experiences we've had with this company have been nothing but positive!  
Glenn has always been prompt at responding to my calls and inquiries, always replying within 24 hours.  He has been honest and forthcoming with information.  He has called in experts to back him up when needed and his prices are very reasonable.

FAQs for swimming pool heaters repair or service projects in Glenwood, MD

Replacing a pool heater costs $3,000 on average. Final pricing depends on the type of heater (gas, electric, or solar) and your pool's size. Factor for swimming pool repair costs, at an average of $3,800. When you start experiencing issues with your pool heater, other equipment and structural failures often follow. Installation is often the least expensive for electric and gas heaters. Heat pumps and solar panels often cost several thousand dollars more to install.

A pool heater’s lifespan is determined by its type and proper upkeep. Solar heaters last 20 to 25 years, electric heat pumps perform for five to 10 years, and gas heaters remain effective for 5 years. Regular pool maintenance safeguards performance and prevents premature failure. Ensuring that you adhere to a strict annual service schedule protects your investment and maintains consistent heating efficiency.

Depending on the size of your pool, location, climate, and current energy prices, you’ll spend up to $20 per hour to heat a pool using propane, $9 per hour using natural gas, and $1 to $2 per hour for a heat pump. Northern climates require more energy and can double the price. Standard estimates allow homeowners to easily estimate the cost of heating a pool for a month. Propane heaters, for example, are known to burn around 1 gallon per hour per 100,000 BTUs.

An electric or gas heat pump will take eight to 14 hours to heat a pool, while a solar heat pump takes 24 to 72 hours. Multiply the number of gallons by 8.34 to get your total pounds of water. Divide this figure by your heater's BTU rating to determine how many hours it takes to raise the water temperature by 1 degree Fahrenheit.

If your pool heater is not raising the water temperature to the desired level, the issue is caused by cold ambient conditions rather than a malfunction. The best solution is to install a solar cover that locks in heat and boosts efficiency. A solar cover costing $120 to $250 enhances heat retention, ensuring your heater performs at its peak. Additionally, verify that all settings—such as thermostat calibration and water circulation—are properly adjusted to support optimal heating.

Regular annual maintenance is crucial to keep your pool heater running efficiently and to avoid high repair costs. Investing $100 to $200 in yearly maintenance prevents issues such as excessive noise, surging energy bills, and malfunctioning controls. This proactive care not only prolongs your heater’s lifespan but also ensures reliable performance throughout the season. Always refer to your warranty guidelines to follow the required maintenance procedures.
