"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."

"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."

"BJ Pool & SPA is a first rate company.  Bob, the owner, has been working with pools for decades and knows everything about pools. He is actually willing to try to repair equipment, unlike many other lesser companies that merely put in new stuff.  If you have any issues with your pool and spa, these are the people to call: they will fix anything and will always provide you with the best options.  Bill, the specialist who came to work on the unusual configuration of equipment for my small indoor pool and spa, demonstrated a great deal of experience, ability and honesty.  BJ Pool & Spa might not seem cheap, however, given their vast knowledge, experience and technical ability, they will provide you with quality service and advice that will save you money in the long run.  Their competence and integrity is extremely reassuring.  It isn't always easy to find a good pool company (this industry isn't as regulated as other professions), and it took me a while to find this one. BJ Pool will be the company I call when I want honest and reliable service

"Backyard Ponds is magic. I have a small backyard pond,stream and waterfall that have been
leaking for years. Various workmen had poured concrete into it, slathered mortar
between stones and sprayed special waterfall foam all over the sides of it. My
pond, stream and waterfall continued to leak. Hilary of Backyard Ponds looked at it for a while, moved one
stone and fixed the leak. How did you do that! I yelled. Well after you work on
enough of these things you get an eye for what the problem could be. Then she
vacuumed all the mud that had been clogging the pum , reattached the waterline
and pump that I could never get to stay together, restacked the rocks along the
edge of the stream so they actually sat on top of each other instead of sliding
down at all angles, and added a few strategically placed rocks to hide the pump
and waterline and cover the rubber sides of the stream. She added a regulator to
the water line so I could make the water run fast and slow. And more. I have had
a pond and stream for fifteen years, and many people have worked on it, from
expensive professioanl landscapers to guys I would swear the contractor picked
up off the street corner. The difference in using someone who specializes in
ponds is stunning. Backyard ponds is
magic.

FAQs for swimming pool heaters repair or service projects in Upper Marlboro, 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.
